[0182] The following description is of the best presently contemplated mode of carrying out the present invention. This description is not to be taken in a limiting sense but is made merely for the purpose of describing the general principles of the invention. For example, each description of random access memory in this specification illustrates only one function or mode in order to avoid complexity in its explanation, however, such description does not mean that only one function or mode can be implemented at a time. In other words, more than one function or mode can be implemented simultaneously by way of utilizing the same random access memory. In addition, the figure numbers are cited after the elements in parenthesis in a manner for example ‘RAM 206 (FIG. 1)’. It is done so merely to assist the readers to have a better understanding of this specification, and must not be used to limit the scope of the claims in any manner since the figure numbers cited are not exclusive. There are only few data stored in each storage area described in this specification. This is done so merely to simplify the explanation and, thereby, to enable the reader of this specification to understand the content of each function with less confusion. Therefore, more than few data (hundreds and thousands of data, if necessary) of the same kind, not to mention, are preferred to be stored in each storage area to fully implement each function described herein. The scope of the invention should be determined by referencing the appended claims.

[0183] FIG. 1 is a simplified block diagram of the Communication Device 200 utilized in the present invention. Referring to FIG. 1, Communication Device 200 includes CPU 211 which controls and administers the overall function and operation of Communication Device 200. CPU 211 uses RAM 206 to temporarily store data and/or to perform calculation to perform its function, and to implement the present invention, modes, functions, and systems explained hereinafter. Video Processor 202 generates analog and/or digital video signals which are displayed on LCD 201. ROM 207 stores the data and programs which are essential to operate Communication Device 200. Wireless signals are received by Antenna 218 and processed by Signal Processor 208. Input signals are input by Input Device 210, such as a dial pad, a joystick, and/or a keypad, and the signals are transferred via Input Interface 209 and Data Bus 203 to CPU 211. Indicator 212 is an LED lamp which is designed to output different colors (e.g., red, blue, green, etc). Analog audio data is input to Microphone 215. A/D 213 converts the analog audio data into a digital format. Speaker 216 outputs analog audio data which is converted into an analog format from digital format by D/A 204. Sound Processor 205 produces digital audio signals that are transferred to D/A 204 and also processes the digital audio signals transferred from A/D 213. CCD Unit 214 captures video image which is stored in RAM 206 in a digital format. Vibrator 217 vibrates the entire device by the command from CPU 211.

[0185] When Communication Device 200 is in the voice communication mode, the analog audio data input to Microphone 215 is converted to a digital format by A/D 213 and transmitted to another device via Antenna 218 in a wireless fashion after being processed by Signal Processor 208, and the wireless signal representing audio data which is received via Antenna 218 is output from Speaker 216 after being processed by Signal Processor 208 and converted to analog signal by D/A 204. For the avoidance of doubt, the definition of Communication Device 200 in this specification includes so-called ‘PDA’. The definition of Communication Device 200 also includes in this specification any device which is mobile and/or portable and which is capable to send and/or receive audio data, text data, image data, video data, and/or other types of data in a wireless fashion via Antenna 218. The definition of Communication Device 200 further includes any micro device embedded or installed into devices and equipments (e.g., VCR, TV, tape recorder, heater, air conditioner, fan, clock, micro wave oven, dish washer, refrigerator, oven, washing machine, dryer, door, window, automobile, motorcycle, and modem) to remotely control these devices and equipments. The size of Communication Device 200 is irrelevant. Communication Device 200 may be installed in houses, buildings, bridges, boats, ships, submarines, airplanes, and spaceships, and firmly fixed therein.

[0186] FIG. 2a illustrates one of the preferred methods of the communication between two Communication Device 200. In FIG. 2a, both Device A and Device B represents Communication Device 200 in FIG. 1. Device A transfers wireless data to Transmitter 301 which Relays the data to Host H via Cable 302. The data is transferred to Transmitter 308 (e.g., a satellite dish) via Cable 320 and then to Artificial Satellite 304. Artificial Satellite 304 transfers the data to Transmitter 309 which transfers the data to Host H via Cable 321. The data is then transferred to Transmitter 307 via Cable 306 and to Device B in a wireless fashion. Device B transfers wireless data to Device A in the same manner.

[0187] FIG. 2b illustrates another preferred method of the communication between two Communication Devices 200. In this example, Device A directly transfers the wireless data to Host H, an artificial satellite, which transfers the data directly to Device B. Device B transfers wireless data to Device A in the same manner.

[0188] FIG. 2c illustrates another preferred method of the communication between two Communication Devices 200. In this example, Device A transfers wireless data to Transmitter 312, an artificial satellite, which Relays the data to Host H, which is also an artificial satellite, in a wireless fashion. The data is transferred to Transmitter 314, an artificial satellite, which Relays the data to Device B in a wireless fashion. Device B transfers wireless data to Device A in the same manner.

The voice recognition function can be performed in terms of software by using Area 261, the voice recognition working area, of RAM 206 (FIG. 1) which is specifically allocated to perform such function as described in FIG. 3, or can also be performed in terms of hardware circuit where such space is specifically allocated in Area 282 of Sound Processor 205 (FIG. 1) for the voice recognition system as described in FIG. 4.

[0191] FIG. 5 illustrates how the voice recognition function is activated. CPU 211 (FIG. 1) periodically checks the input status of Input Device 210 (FIG. 1) (S1). If the CPU 211 detects a specific signal input from Input Device 210 (S2) the voice recognition system which is described in FIG. 2 and/or FIG. 3 is activated. As another embodiment, the voice recognition system can also be activated by entering predetermined phrase, such as ‘start voice recognition system’ via Microphone 215 (FIG. 1).

[0192] <<Voice Recognition—Dialing/Auto-Off During Call Function>>

[0193] FIG. 6a and FIG. 6b illustrate the operation of the voice recognition in the present invention. Once the voice recognition system is activated (S1) the analog audio data is input from Microphone 215 (FIG. 1) (S2). The analog audio data is converted into digital data by A/D 213 (FIG. 1) (S3). The digital audio data is processed by Sound Processor 205 (FIG. 1) to retrieve the text and numeric information therefrom (S4). Then the numeric information is retrieved (S5) and displayed on LCD 201 (FIG. 1) (S6). If the retrieved numeric information is not correct (S7), the user can input the correct numeric information manually by using Input Device 210 (FIG. 1) (S8). Once the sequence of inputting the numeric information is completed and after the confirmation process is over (S9), the entire numeric information is displayed on LCD 201 and the sound is output from Speaker 216 under control of CPU 211 (S10). If the numeric information is correct (S11), Communication Device 200 (FIG. 1) initiates the dialing process by utilizing the numeric information (S12). The dialing process continues until Communication Device 200 is connected to another device (S13). Once CPU 211 detects that the line is connected it automatically deactivates the voice recognition system (S14).

[0194] As described in FIG. 7, CPU 211 (FIG. 1) checks the status of Communication Device 200 periodically (S1) and remains the voice recognition system offline during call (S2). If the connection is severed, i.e., user hangs up, then CPU 211 reactivates the voice recognition system (S3).

[0195] <<Voice Recognition Tag Function>>

[0196] FIGS. 8 through 12 describes the method of inputting the numeric information in a convenient manner.

[0197] As described in FIG. 8, RAM 206 includes Table #1 (FIG. 8) and Table #2 (FIG. 9). In FIG. 8, audio information #1 corresponds to tag ‘Scott.’ Namely audio information, such as wave data, which represents the sound of ‘Scott’ (sounds like ‘S-ko-t’) is registered in Table #1, which corresponds to tag ‘Scott’. In the same manner audio information #2 corresponds to tag ‘Carol’; audio information #3 corresponds to tag ‘Peter’; audio information #4 corresponds to tag ‘Amy’; and audio information #5 corresponds to tag ‘Brian.’ In FIG. 9, tag ‘Scott’ corresponds to numeric information ‘(916) 411-2526’; tag ‘Carol’ corresponds to numeric information ‘(418) 675-6566’; tag ‘Peter’ corresponds to numeric information ‘(220) 890-1567’; tag ‘Amy’ corresponds to numeric information ‘(615) 125-3411’; and tag ‘Brian’ corresponds to numeric information ‘(042) 645-2097.’FIG. 11 illustrates how CPU 211 (FIG. 1) operates by utilizing both Table #1 and Table #2. Once the audio data is processed as described in S4 of FIG. 6, CPU 211 scans Table #1 (S1). If the retrieved audio data matches with one of the audio information registered in Table #1 (S2), CPU 211 scans Table #2 (S3) and retrieves the corresponding numeric information from Table #2 (S4).

[0198] FIG. 10 illustrates another embodiment of the present invention. Here, RAM 206 includes Table #A instead of Table #1 and Table #2 described above. In this embodiment, audio info #1 (i.e., wave data which represents the sound of ‘Scot’) directly corresponds to numeric information ‘(916) 411-2526.’ In the same manner audio info #2 corresponds to numeric information ‘(410) 675-6566’; audio info #3 corresponds to numeric information ‘(220) 890-1567’; audio info #4 corresponds to numeric information ‘(615) 125-3411’; and audio info #5 corresponds to numeric information ‘(042) 645-2097.’FIG. 12 illustrates how CPU 211 (FIG. 1) operates by utilizing Table #A. Once the audio data is processed as described in S4 of FIG. 6, CPU 211 scans Table #A (S1). If the retrieved audio data matches with one of the audio information registered in Table #A (S2), it retrieves the corresponding numeric information therefrom (S3).

[0199] As another embodiment, RAM 206 may contain only Table #2 and tag can be retrieved from the voice recognition system explained in FIGS. 3 through 7. Namely, once the audio data is processed by CPU 211 (FIG. 1) as described in S4 of FIG. 6 and retrieves the text data therefrom and detects one of the tags registered in Table #2 (e.g., ‘Scot’), CPU 211 retrieves the corresponding numeric information (e.g., ‘(916) 411-2526’) from the same table.

[0200] <<Voice Recognition Noise Filtering Function>>

[0201] FIGS. 13 through 15 describes the method of minimizing the undesired effect of the background noise when utilizing the voice recognition system.

[0202] As described in FIG. 13, RAM 206 (FIG. 1) includes Area 255 and Area 256. Sound audio data which represents background noise is stored in Area 255, and sound audio data which represents the beep, ringing sound and other sounds which are emitted from the Communication Device 200 are stored in Area 256.

[0203] FIG. 14 describes the method to utilize the data stored in Area 255 and Area 256 described in FIG. 13. When the voice recognition system is activated as described in FIG. 5, the analog audio data is input from Microphone 215 (FIG. 1) (S1). The analog audio data is converted into digital data by A/D 213 (FIG. 1) (S2). The digital audio data is processed by Sound Processor 205 (FIG. 1) (S3) and compared to the data stored in Area 255 and Area 256 (S4). Such comparison can be done by either Sound Processor 205 or CPU 211 (FIG. 1). If the digital audio data matches to the data stored in Area 255 and/or Area 256, the filtering process is initiated and the matched portion of the digital audio data is deleted as background noise. Such sequence of process is done before retrieving text and numeric information from the digital audio data.

[0204] FIG. 14a describes the method of updating Area 255. When the voice recognition system is activated as described in FIG. 5, the analog audio data is input from Microphone 215 (FIG. 1) (S1). The analog audio data is converted into digital data by A/D 213 (FIG. 1) (S2). The digital audio data is processed by Sound Processor 205 (FIG. 1) or CPU 211 (FIG. 1) (S3) and the background noise is captured (S4). CPU 211 (FIG. 1) scans Area 255 and if the captured background noise is not registered in Area 255, it updates the sound audio data stored therein (S5).

[0205] FIG. 15 describes another embodiment of the present invention. CPU 211 (FIG. 1) routinely checks whether the voice recognition system is activated (S1). If the system is activated (S2), the beep, ringing sound, and other sounds which are emitted from Communication Device 200 are automatically turned off in order to minimize the miss recognition process of the voice recognition system (S3).

[0206] <<Voice Recognition Auto-Off Function>>

[0207] The voice recognition system can be automatically turned off to avoid glitch as described in FIG. 16. When the voice recognition system is activated (S1), CPU 211 (FIG. 1) automatically sets a timer (S2). The value of timer (i.e., the length of time until the system is deactivated) can be set manually by the user. The timer is incremented periodically (S3), and if the incremented time equals to the predetermined value of time as set in S2 (S4), the voice recognition system is automatically deactivated (S5).

[0208] <<Voice Recognition Email Function (1)>>

[0209] FIGS. 17a and 17b illustrate the first embodiment of the function of typing and sending e-mails by utilizing the voice recognition system. Once the voice recognition system is activated (S1), the analog audio data is input from Microphone 215 (FIG. 1) (S2). The analog audio data is converted into digital data by A/D 213 (FIG. 1) (S3). The digital audio data is processed by Sound Processor 205 (FIG. 1) or CPU 211 (FIG. 1) to retrieve the text and numeric information therefrom (S4). The text and numeric information are retrieved (S5) and are displayed on LCD 201 (FIG. 1) (S6). If the retrieved information is not correct (S7), the user can input the correct text and/or numeric information manually by using the Input Device 210 (FIG. 1) (S8). If inputting the text and numeric information is completed (S9) and CPU 211 detects input signal from Input Device 210 to send the e-mail (S10), the dialing process is initiated (S11). The dialing process is repeated until Communication Device 200 is connected to Host H (S12), and the e-mail is sent to the designated address (S13).

[0210] <<Voice Recognition—Speech-to-Text Function>>

[0211] FIG. 18 illustrates the speech-to-text function of Communication Device 200 (FIG. 1).

[0212] Once Communication Device 200 receives a transmitted data from another device via Antenna 218 (FIG. 1) (S1), Signal Processor 208 (FIG. 1) processes the data (e.g., wireless signal error check and decompression) (S2), and the transmitted data is converted into digital audio data (S3). Such conversion can be rendered by either CPU 211 (FIG. 1) or Signal Processor 208. The digital audio data is transferred to Sound Processor 205 (FIG. 1) via Data Bus 203 and text and numeric information are retrieved therefrom (S4). CPU 211 designates the predetermined font and color to the text and numeric information (S5) and also designates a tag to such information (S6). After these tasks are completed the tag and the text and numeric information are stored in RAM 206 and displayed on LCD 201 (S7).

[0213] FIG. 19 illustrates how the text and numeric information as well as the tag are displayed. On LCD 201 the text and numeric information 702 (‘XXXXXXXXX’) are displayed with the predetermined font and color as well as with the tag 701 (‘John’).

Relays R1 through R20 are preferably located on ground, however, are also permitted to be installed in artificial satellites as described in the foregoing patents and the references cited thereof in order to cover wider geographical range. The Relays may also be installed in houses, buildings, bridges, boats, ships, submarines, airplanes, and spaceships. In addition, Host H may be carried by houses, buildings, bridges, boats, ships, submarines, airplanes, and spaceships. In stead of utilizing Cables C1 through C5, Relays R1 through R20 (and other relays described in this specification) may be connected to Transmitter T in a wireless fashion, and Transmitter T may be connected to Host H in a wireless fashion.

[0225] FIGS. 21 through 26 illustrate how the positioning system is performed. Assuming that Device A, Communication Device 200, seeks to detect the position of Device B, another Communication Device 200, which is located somewhere in the matrix of Relays illustrated in FIG. 20b.

[0226] As described in FIG. 21, first of all the device ID of Device B is entered by utilizing Input Device 210 (FIG. 1) or the voice recognition system of Device A installed therein (S1). The device ID may be its corresponding phone number. A request data including the device ID is sent to Host H (FIG. 20a) from Device A (S2).

[0227] As illustrated in FIG. 22, Host H (FIG. 20a) periodically receives data from Device A (S1). If the received data is a request data (S2), Host H, first of all, searches its communication log which records the location of Device B when it last communicated with Host H (S3). Then Host H sends search signal from the Relays described in FIG. 20b which are located within 100-meter radius from the location registered in the communication log. If there is no response from Device B (S5), Host H sends a search signal from all Relays (from R1 to R20 in FIG. 20b) (S6).

[0228] As illustrated in FIG. 23, Device B periodically receives data from Host H (FIG. 20a) (S1). If the data received is a search signal (S2), Device B sends a response signal to Host H (S3).

[0229] As illustrated in FIG. 24 Host H (FIG. 20a) periodically receives data from Device B (S1). If the data received is a response signal (S2), Host H locates the geographic position of Device B by utilizing the method described in FIGS. 20a and 20b (S3), and sends the location data and the relevant map data of the area where Device B is located to Device A (S4).

[0230] As illustrated in FIG. 25, Device A periodically receives data from Host H (FIG. 20a) (S1). If the data received is the location data and the relevant map data mentioned above (S2), Device A displays the map based on the relevant map data and indicates the current location of Device B thereon based on the location data received (S3).

[0231] Device A can continuously track down the current location of Device B as illustrated in FIG. 26. First, Device A sends a request data to Host H (FIG. 20a) (S1). As soon as Host H receives the request data (S2), it sends a search signal in the manner illustrated in FIG. 22 (S3). As soon as Device B receives the search signal (S4), it sends a response signal to Host H (S5). Based on the response signal, Host H locates the geographic location of Device B with the method described in FIGS. 20a and 20b (S6). Then Host H sends to Device A a renewed location data and a relevant map data of the area where Device B is currently located (S7). As soon as these data are received (S8), Device A displays the map based on the relevant map data and indicates the updated location based on the renewed location data (S9). If Device B is still within the specified area Device A may use the original relevant map data. As another embodiment of the present invention, S1 through S4 may be omitted and make Device B send a response signal continuously to Host H until Host H sends a command signal to Device B to cease sending the response signal.

[0232] <<Positioning System—Automatic Silent Mode>>

[0233] FIGS. 27a through 32g illustrate the automatic silent mode of Communication Device 200 (FIG. 1).

[0234] In FIG. 27a, Relay R1 is connected to Cable C1, Relay R2 is connected to Cable C2, Relay R3 is connected to Cable C3, and Relay R4 is connected to Cable C4. Cables C1, C2, C3, and C4 are connected to Transmitter T, which is connected to Host H by Cable C5. The Relays (R1 through R 20) are located throughout the predetermined area in the pattern illustrated in FIG. 27b. The system illustrated in FIGS. 27a and 27b is designed to pinpoint the position of Communication Device 200 by using the method so-called ‘global positioning system’ or ‘GPS.’ As stated hereinbefore, such function can be enabled by the technologies primarily introduced in the inventions in the foregoing patents and the references cited thereof. The Relays R1 through R20 are preferably located on ground, however, are also permitted to be installed in artificial satellites as described in the foregoing patents and the references cited thereof in order to cover wider geographical range. In addition, Host H may be carried by an artificial satellite and utilize the formation as described in FIGS. 2a, 2b, and 2c.

[0235] As illustrated in FIG. 28, the user of Communication Device 200 may set the silent mode by Input Device 210 (FIG. 1) or by utilizing the voice recognition system installed therein. When Communication Device 200 is in the silent mode, (a) the ringing sound is turned off, (b) Vibrator 217 (FIG. 1) activates when Communication Device 200 receives call, and/or (c) Communication Device 200 sends an automatic response to the caller device when a call is received (S1). The user may, at his discretion, select any of these predetermined functions of the automatic silent mode.

[0236] FIG. 29 illustrates how the automatic silent mode is activated. Communication Device 200 periodically checks its present location with the method so-called ‘global positioning system’ or ‘GPS’ by using the system illustrated in FIGS. 27a and 27b (S1). Communication Device 200 then compares the present location and the previous location (S2). If the difference of the two values is more than the specified amount X, i.e., when the moving velocity of Communication Device 200 exceeds the predetermined value (S3), the silent mode is activated and (a) the ringing sound is automatically turned off, (b) Vibrator 217 (FIG. 1) activates, and/or (c) Communication Device 200 sends an automatic response to the caller device according to the user's setting (S4). Here, the silent mode is automatically activated because the user of Communication Device 200 is presumed to be on an automobile and is not in a situation to freely answer the phone, or the user is presumed to be riding a train and does not want to disturb other passengers.

[0237] As another embodiment of the present invention, the automatic silent mode may be administered by Host H (FIG. 27a). As illustrated in FIG. 30, the silent mode is set in the manner described in FIG. 28 (S1) and Communication Device 200 sends to Host H a request signal indicating that it is in the silent mode (S2).

[0238] As described in FIG. 31, when Host H (FIG. 27a) detects a call to Communication Device 200 after receiving the request signal, it checks the current location of Communication Device 200 (S1) and compares it with the previous location (S2). If the difference of the two values is more than the specified amount X, i.e., when the moving velocity of Communication Device 200 exceeds the predetermined value (S3), Host H sends a notice signal to Communication Device 200 indicating that it has received an incoming call (S4).

[0239] As illustrated in FIG. 32, Communication Device 200 receives data periodically from Host H (FIG. 27a) (S1). If the received data is a notice signal (S2), Communication Device 200 activates the silent mode (S3) and (a) the ringing sound is automatically turned off, (b) Vibrator 217 (FIG. 1) activates, and/or (c) Communication Device 200 sends an automatic response to the caller device according to the user's setting. The automatic response may be sent from Host H instead.

[0240] As another embodiment of the present invention, a train route data may be utilized. As illustrated in FIG. 32a, a train route data is stored in Area 263 of RAM 206. The train route data contains three-dimensional train route map including the location data of the train route. FIG. 32b illustrates how the train route data is utilized. CPU 211 (FIG. 1) periodically checks the present location of Communication Device 200 by the method described in FIGS. 27a and 27b (S1). Then CPU 211 compares with the train route data stored in Area 263 of RAM 206 (S2). If the present location of Communication Device 200 matches the train route data (i.e., if Communication Device 200 is located on the train route) (S3), the silent mode is activated in the manner described above (S4). The silent mode is activated because the user of Communication Device 200 is presumed to be currently on a train and may not want to disturb the other passengers on the same train.

[0241] As another embodiment of the present invention, such function can be delegated to Host H (FIG. 27a) as described in FIG. 32c. Namely, Host H (FIG. 27a) periodically checks the present location of Communication Device 200 by the method described in FIGS. 27a and 27b (S1). Then Host H compares the present location with the train route data stored in its own storage (not shown) (S2). If the present location of communication 200 matches the train route data (i.e., if Communication Device 200 is located on the train route) (S3) Host H sends a notice signal to Communication Device 200 thereby activating the silent mode in the manner described above (S4).

[0242] Another embodiment is illustrated in FIGS. 32f and 32g. As illustrated in FIG. 32f, Relays R 101, R 102, R 103, R 104, R 105, R 106, which perform the same function to the Relays described in FIG. 27a and FIG. 27b, are installed in Train Tr. The signals from these Relays are sent to Host H illustrated in FIG. 27a. Relays R 101 through R 106 emit inside-the-train signals which are emitted only inside Train Tr. FIG. 32g illustrates how Communication Device 200 operates inside Train Tr. Communication Device 200 periodically checks the signal received in Train Tr (S1). If Communication Device 200 determines that the signal received is an inside-the-train signal (S2), it activates the silent mode in the manner described above (S3).

[0243] <<Positioning System—Auto Response Mode>>

[0244] FIG. 32d and FIG. 32e illustrates the method to send an automatic response to a caller device when the silent mode is activated.

[0245] Assume that the caller device, a Communication Device 200, intends to call a callee device, another Communication Device 200 via Host H (FIG. 27a). As illustrated in FIG. 32d, the caller device dials the callee device and the dialing signal is sent to Host H (S1). Host H checks whether the callee device is in the silent mode (S2). If Host H detects that the callee device is in the silent mode, it sends a predetermined auto response which indicates that the callee is probably on a train and may currently not be available, which is received by the caller device (S3). If the user of the caller device still desires to request for connection and certain code is input from Input Device 210 (FIG. 1) or by the voice recognition system (S4), a request signal for connection is sent and received by Host H (S5), and the line is connected between the caller device and the callee device via Host H (S6).

[0246] As another embodiment of the present invention, the task of Host H (FIG. 27a) which is described in FIG. 32d may be delegated to the callee device as illustrated in FIG. 32e. The caller device dials the callee device and the dialing signal is sent to the callee device via Host H (S1). The callee device checks whether it is in the silent mode (S2). If the callee device detects that it is in the silent mode, it sends an predetermined auto response which indicates that the callee is probably on a train and may currently not be available, which is sent to the caller device via Host H (S3). If the user of the caller device still desires to request for connection and certain code is input from Input Device 210 (FIG. 1) or by the voice recognition system (S4), a request signal for connection is sent to the callee device via Host H (S5), and the line is connected between the caller device and the callee device via Host H (S6).

[0247] <<Positioning System—Summary>>

[0248] The foregoing inventions may be summarized as the following.

[0249] (1) A positioning system comprising a first device, a host, and a second device wherein a device ID of said second device is input into said first device, said device ID is sent to said host, said host sends a search signal to which said second device responds, said host sends to the first device location data indicating the location of said second device, and said first device displays the location of said second device thereby enabling said first device to identify the location of said second device. Where said first device is a communication device, said first device includes an antenna, said antenna sends positioning signal to identify the location of said second device, and said antenna also sends communication signal thereby enabling the user of said first device to identify the location of said second device as well as utilizing said communication device for means of communication.

[0250] (2) A communication device wherein the moving velocity of said communication device is checked and when said moving velocity exceeds a predetermined value said communication device refrains from emitting sound thereby preventing other persons being present near said communication device from being disturbed.

[0251] (3) A communication device wherein the location of said communication device is compared to a route data and said communication device refrains from emitting sound if said location of said communication device is determined to match said route data thereby preventing other persons being present near said communication device from being disturbed.

[0252] (4) A communication system comprising a first communication device and a second communication device wherein said first communication device receives an automatic response if said second communication device is in a certain mode and said first communication device is enable to be connected to said second communication device upon said second device sending a request thereby preventing other persons being present near said first communication device from being disturbed.

[0253] (5) A communication system comprising a communication device and a plurality of signal emitter wherein said communication device refrains from emitting sound upon receiving a certain signal from said signal emitter thereby preventing other persons being present near said communication device from being disturbed.

[0254] <<Auto Backup System>>

[0255] FIGS. 33 through 37 illustrate the automatic backup system of Communication Device 200 (FIG. 1).

[0256] As illustrated in FIG. 33, RAM 206 (FIG. 1) includes areas to store the data essential to the user of Communication Device 200, such as Area 278 for a phone list, Area 279 for an address book, Area 280 for email data, Area 281 for software A, Area 282 for software B, Area 283 for software C, Area 284 for Data D, Area 285 for Data E. RAM 206 also includes Area 264, i.e., the selected data info storage area, which will be explained in details hereinafter.

[0257] As described in FIG. 34, the user selects data by utilizing Input Device 210 (FIG. 1) or the voice recognition system which he/she intends to be automatically backed up (S1). The selected data are written in Area 264, the selected data info storage area (S2).

[0258] The overall operation of this function is illustrated in FIGS. 35a and 35b. First of all, a timer (not shown) is set by a specific input signal produced by Input Device 210 (FIG. 1) or by the voice recognition system (S1). The timer is incremented periodically (S2) and when the incremented value equals the predetermined value (S3), CPU 211 (FIG. 1) initiates the dialing process (S4). The dialing process continues until Communication Device 200 is connected to Host H explained in FIG. 37 (S5). Once the line is connected, CPU 211 reads the information stored in Area 264 (S6) and based on such information it initiates to transfer the selected data from RAM 206 to Host H (S7). The transfer continues until all of the selected data are transferred to Host H (S8), and the line is disconnected thereafter (S9). This backup sequence can be initiated automatically and periodically by using a timer or manually. As another embodiment of the present invention, instead of selecting the data that are to be backed up, all data in RAM 206 (FIG. 1) can be transferred to Host H.

[0259] FIG. 36 illustrates the basic structure of the data transferred to Host H. Transferred data 601 includes Header 602, device ID 603, selected data 604 and Footer 605. Device ID 603 is the identification number of Communication Device 200 preferably its phone number, and selected data 604 is a pack of data which is transferred from RAM 206 to Host H based on information stored in Area 264. Header 602 and Footer 605 indicates the beginning and the end of the Transferred Data 601 respectively.

[0260] FIG. 37 illustrates the basic structure of Host H. Host H includes backup data storage Area 401 which is used to backup all of the backup data transferred from all Communication Devices 200. Host H stores the Transferred Data 601 (FIG. 36) to the designated area based on the device ID included in Transferred Data 601. For example, Transferred Data 601 transferred from Device A is stored in Area 412 as Backup Data A. In the same manner Transferred Data 601 transferred from Device B is stored in Area 413 as Backup Data B; Transferred Data 601 transferred from Device C is stored in Area 414 as Backup Data C; Transferred Data 601 transferred from device D is stored in Area 415 as Backup Data D; Transferred Data 601 transferred from device E is stored in Area 416 as Backup Data E; and Transferred Data 601 transferred from device F is stored in Area 417 as Backup Data F.

[0261] <<Auto Backup—Summary>>

[0262] The foregoing invention may be summarized as the following.

[0263] A communication system comprising a host and a plurality of communication device wherein said host includes a plurality of storage areas and each of said plurality of communication device includes a storage area, and data stored in said storage area of said communication device are manually and/or periodically transferred to one of the designated storage areas of said host thereby enabling the users of said plurality of communication device to retrieve data when said plurality of communication device are lost or broken.

[0264] <<Signal Amplifier>>

[0265] FIG. 38 illustrates a signal amplifier utilized for automobiles and other transportation carriers, such as trains, airplanes, space shuttles, and motor cycles.

[0266] As described in FIG. 38, Automobile 835 includes Interface 503, an interface detachably connected to Communication Device 200, which is connected to Amplifier 502 via Cable 505. Amplifier 502 is connected to Antenna 501 via Cable 504 and Connector 507 as described in this drawing. The signal produced by Communication Device 200 is transferred to Interface 503. Then the signal is transferred to Amplifier 502 via Cable 505 where the signal is amplified. The amplified signal is transferred to Antenna 501 via Cable 504 and Connector 507, which transmits the amplified signal to Host H (not shown). The receiving signal is received by Antenna 501 and transferred to Amplifier 502 via Connector 507 and Cable 504, and then is transferred to Interface 503 via Cable 505, which transfers the amplified signal to Communication Device 200.

[0267] <<Signal Amplifier—Summary>>

[0268] The foregoing invention may be summarized as the following.

[0269] A transportation carrier which is primarily designed to carry person or persons comprising an interface which is detachably connectable to a communication device, an amplifier which is connected to said interface and which amplifies the signal produced by said communication device, and an transmitter which is connected to said amplifier and which transmits said signal amplified by said amplifier.

[0270] <<Audio/Video Data Capturing System>>

[0271] FIGS. 39 through 44 illustrate the audio/video capturing system of Communication Device 200 (FIG. 1).

[0272] Assuming that Device A, a Communication Device 200, captures audio/video data and transfers such data to Device B, another Communication Device 200, via a host (not shown). Primarily video data is input from CCD Unit 214 (FIG. 1) and audio data is input from Microphone 215 of (FIG. 1) of Device A.

[0273] As illustrated in FIG. 39, RAM 206 (FIG. 1) includes Area 267 which stores video data, Area 268 which stores audio data, and Area 265 which is a work area utilized for the process explained hereinafter.

[0274] As described in FIG. 40, the video data input from CCD Unit 214 (FIG. 1) (S1a) is converted from analog data to digital data (S2a) and is processed by Video Processor 202 (FIG. 1) (S3a). Area 265 (FIG. 39) is used as work area for such process. The processed video data is stored in Area 267 (FIG. 39) of RAM 206 (S4a) and is displayed on LCD 201 (FIG. 1) (S5a). As described in the same drawing, the audio data input from Microphone 215 (FIG. 1) (S1b) is converted from analog data to digital data by A/D 213 (FIG. 1) (S2b) and is processed by Sound Processor 205 (FIG. 1) (S3b). Area 265 is used as work area for such process.

[0310] <<Timer Email Function>>

[0311] FIGS. 53a and 53b illustrate the method of sending emails from Communication Device 200 (FIG. 1) by utilizing a timer.

[0312] Address data, i.e., email address is input by utilizing Input Device 210 (FIG. 1) or via voice recognition system explained in FIG. 3, FIG. 4, FIG. 5, FIG. 13, FIG. 14, FIG. 14a, FIG. 15, FIG. 16 and/or FIG. 17 (S1) and the text data, the text of the email message is input by the same manner (S2). The address data and the text data are automatically saved in RAM 206 (FIG. 1) (S3). The sequence of S1 through S3 is repeated (i.e., writing more than one email) until a specified input signal is input from Input Device 210 (FIG. 1) or by utilizing the voice recognition system explained above. Once inputting both the address data and the text data (which also includes numeric data, images and programs) are completed a timer (not shown) is set by Input Device 210 or by utilizing the voice recognition system (S5), and the timer is incremented periodically (S6) until the timer value equals the predetermined value specified in S5 (S7). A dialing process is continued (S8) until the line is connected (S9) and the text data are sent thereafter to email addresses specified in S1 (S10). All of the emails are sent (S11) and the line is disconnected thereafter (S12).

[0313] As another embodiment of the present invention a specific time may be input by Input Device 210 and send the text data on the specific time (i.e., a broad meaning of ‘timer’).

[0317] <<Call Blocking Function>>

[0318] FIGS. 54 through 56 illustrates the so-called ‘call blocking’ function of Communication Device 200 (FIG. 1).

[0319] As illustrated in FIG. 54, RAM 206 (FIG. 1) includes Area 273 and Area 274. Area 273 stores phone numbers that should be blocked. In the example illustrated in FIG. 54, Phone #1, Phone #2, and Phone #3 are blocked. Area 274 stores a message data, preferably a wave data, stating that the phone can not be connected.

[0320] FIG. 55 illustrates the operation of Communication Device 200. When Communication Device 200 receives a call (S1), CPU 211 (FIG. 1) scans Area 273 (FIG. 54) of RAM 206 (S2). If the phone number of the incoming call matches one of the phone numbers stored in Area 273 (S3), CPU 211 sends the message data stored in Area 274 (FIG. 54) of RAM 206 to the caller device (S4) and disconnects the line (S5).

[0321] FIG. 56 illustrates the method of updating Area 273 (FIG. 54) of RAM 206. Assuming that the phone number of the incoming call does not match any of the phone numbers stored in Area 273 of RAM 206 (see S3 of FIG. 55). In that case, Communication Device 200 is connected to the caller device. However, the user of Communication Device 200 may decide to have such number ‘blocked’ after all. If that is the case, the user dials ‘999’ while the line is connected. Technically CPU 211 (FIG. 1) periodically checks the signals input from Input Device 210 (FIG. 1) (S1). If the input signal represents a numerical data ‘999’ from Input Device 210 (S2), CPU 211 adds the phone number of the pending call to Area 273 (S3) and sends the message data stored in Area 274 (FIG. 54) of RAM 206 to the caller device (S4). The line is disconnected thereafter (S5).

[0322] FIGS. 57 through 59 illustrate another embodiment of the present invention.

[0323] As illustrated in FIG. 57, Host H (not shown) includes Area 403 and Area 404. Area 403 stores phone numbers that should be blocked to be connected to Communication Device 200. In the example illustrated in FIG. 57, Phone #1, Phone #2, and Phone #3 are blocked for Device A; Phone #4, Phone #5, and Phone #6 are blocked for Device B; and Phone #7, Phone #8, and Phone #9 are blocked for Device C. Area 404 stores a message data stating that the phone can not be connected.

[0324] FIG. 58 illustrates the operation of Host H (not shown). Assuming that the caller device is attempting to connect to Device B, Communication Device 200. Host H periodically checks the signals from all Communication Device 200 (S1). If Host H detects a call for Device B (S2), it scans Area 403 (FIG. 57) (S3) and checks whether the phone number of the incoming call matches one of the phone numbers stored therein for Device B (S4). If the phone number of the incoming call does not match any of the phone numbers stored in Area 403, the line is connected to Device B (S5b). On the other hand, if the phone number of the incoming call matches one of the phone numbers stored in Area 403, the line is ‘blocked,’ i.e., not connected to Device B (S5a) and Host H sends the massage data stored in Area 404 (FIG. 57) to the caller device (S6).

[0325] FIG. 59 illustrates the method of updating Area 403 (FIG. 57) of Host H. Assuming that the phone number of the incoming call does not match any of the phone numbers stored in Area 403 (see S4 of FIG. 58). In that case, Host H allows the connection between the caller device and Communication Device 200, however, the user of Communication Device 200 may decide to have such number ‘blocked’ after all. If that is the case, the user simply dials ‘999’ while the line is connected. Technically Host H (FIG. 57) periodically checks the signals input from Input Device 210 (FIG. 1) (S1). If the input signal represents ‘999’ from Input Device 210 (FIG. 1) (S2), Host H adds the phone number of the pending call to Area 403 (S3) and sends the message data stored in Area 404 (FIG. 57) to the caller device (S4). The line is disconnected thereafter (S5).

[0326] As another embodiment of the method illustrated in FIG. 59, Host H (FIG. 57) may delegate some of its tasks to Communication Device 200 (this embodiment is not shown in drawings). Namely, Communication Device 200 periodically checks the signals input from Input Device 210 (FIG. 1). If the input signal represents a numeric data ‘999’ from Input Device 210, Communication Device 200 sends to Host H a block request signal as well as with the phone number of the pending call. Host H, upon receiving the block request signal from Communication Device 200, adds the phone number of the pending call to Area 403 (FIG. 57) and sends the message data stored in Area 404 (FIG. 57) to the caller device. The line is disconnected thereafter.

[0333] As illustrated in FIG. 60, Host H includes account data storage Area 405. All of the account data of the users of Communication Device 200 who have signed up for the online payment service are stored in Area 405. In the example described in FIG. 60, Account A stores the relevant account data of the user using Device A; Account B stores the relevant account data of the user using Device B; Account C stores the relevant account data of the user using Device C; and Account D stores the relevant account data of the user using device D. Here, Devices A, B, C, and D are Communication Device 200.

[0334] FIGS. 61a and 61b illustrate the operation of the payer device, Communication Device 200. Assuming that Device A is the payer device and Device B is the payee device. Account A explained in FIG. 60 stores the account data of the user of Device A, and Account B explained in the same drawing stores the account data of the user of Device B. As illustrated in FIG. 61a, LCD 201 (FIG. 1) of Device A displays the balance of Account A by receiving the relevant data from Host H (FIG. 60) (S1). From the signal input from Input Device 210 (FIG. 1), the payer's account and the payee's account are selected (in the present example, Account A as the payer's account and Account B as the payee's account are selected), and the amount of payment and the device ID (in the present example, Device A as the payer's device and Device B as the payee's device) are input via Input Device 210 (S2). If the data input from Input Device 210 is correct (S3), CPU 211 (FIG. 1) of Device A prompts for other payments. If there are other payments to make, the sequence of S1 through S3 is repeated until all of the payments are made (S4). The dialing process is initiated and repeated thereafter (S5) until the line is connected to Host H (FIG. 60) (S6). Once the line is connected, Device A sends the payment data to Host H (S7). The line is disconnected when all of the payment data including the data produced in S2 are sent to Host H (S8 and S9).

[0335] FIG. 62 illustrates the payment data described in S7 of FIG. 61b. Payment data 620 is composed of Header 621, Payer's Account Information 622, Payee's Account Information 623, amount data 624, device ID data 625, and Footer 615. Payer's Account Information 622 represents the information regarding the payer's account data stored in Host H (FIG. 60) which is, in the present example, Account A. Payee's Account Information 623 represents the information regarding the payee's account data stored in Host H which is, in the present example, Account B. Amount Data 624 represents the amount of monetary value either in the U.S. dollars or in other currencies which is to be transferred from the payer's account to the payee's account. The device ID data represents the data of the payer's device and the payee's device, i.e., in the present example, Device A and Device B.

[0336] FIG. 63 illustrates the basic structure of the payment data described in S7 of FIG. 61b when multiple payments are made, i.e., when more than one payment is made in S4 of FIG. 61a. Assuming that three payments are made in S4 of FIG. 61a. In that case, Payment Data 630 is composed of Header 631, Footer 635, and three data sets, i.e., Data Set 632, Data Set 633, Data Set 634. Each data set represents the data components described in FIG. 62 excluding Header 621 and Footer 615.

[0337] FIG. 64 illustrates the operation of Host H (FIG. 60). After receiving payment data from Device A described in FIGS. 62 and 63, Host H retrieves therefrom the payer's account information (in the present example Account A), the payee's account information (in the present example Account B), the amount data which represents the monetary value, and the device IDs of both the payer's device and the payee's device (in the present example Device A and Device B) (S1). Host H, based on such data, subtracts the monetary value represented by the amount data from the payer's account (in the present example Account A) (S2), and adds the same amount to the payee's account (in the present example Account B) (S3). If there are other payments to make, i.e., if Host H received a payment data which has a structure of the one described in FIG. 63, the sequence of S2 and S3 is repeated as many times as the amount of the data sets are included in such payment data.

[0341] <<Navigation System>>

[0342] FIGS. 65 through 74 illustrate the navigation system of Communication Device 200 (FIG. 1).

[0343] As illustrated in FIG. 65, RAM 206 (FIG. 1) includes Area 275, Area 276, Area 277, and Area 295. Area 275 stores a plurality of map data, two-dimensional (2D) image data, which are designed to be displayed on LCD 201 (FIG. 1). Area 276 stores a plurality of object data, three-dimensional (3D) image data, which are also designed to be displayed on LCD 201. The object data are primarily displayed by a method so-called ‘texture mapping’ which is explained in details hereinafter. Here, the object data include the three-dimensional data of various types of objects that are displayed on LCD 201, such as bridges, houses, hotels, motels, inns, gas stations, restaurants, streets, traffic lights, street signs, trees, etc. Area 277 stores a plurality of location data, i.e., data representing the locations of the objects stored in Area 276. Area 277 also stores a plurality of data representing the street address of each object stored in Area 276. In addition, Area 277 stores the current position data of Communication Device 200 and the Destination Data which are explained in details hereafter. The map data stored in Area 275 and the location data stored in Area 277 are linked each other. Area 295 stores a plurality of attribution data attributing to the map data stored in Area 275 and location data stored in Area 277, such as road blocks, traffic accidents, and road constructions, and traffic jams. The attribution data stored in Area 295 is updated periodically by receiving an updated data from a host (not shown).

[0344] As illustrated in FIG. 66, Video Processor 202 (FIG. 1) includes texture mapping processor 290. Texture mapping processor 290 produces polygons in a three-dimensional space and ‘pastes’ textures to each polygon. The concept of such method is described in the following patents and the references cited thereof: U.S. Pat. No. 5,870,101, U.S. Pat. No. 6,157,384, U.S. Pat. No. 5,774,125, U.S. Pat. No. 5,375,206, and/or U.S. Pat. No. 5,925,127.

[0345] As illustrated in FIG. 67, the voice recognition system is activated when the CPU 211 (FIG. 1) detects a specific signal input from Input Device 210 (FIG. 1) (S1). After the voice recognition system is activated, the input current position mode starts and the current position of Communication Device 200 is input by voice recognition system explained in FIG. 3, FIG. 4, FIG. 5, FIG. 13, FIG. 14, FIG. 14a, FIG. 15, FIG. 16 and/or FIG. 17 (S2). The current position can also be input from Input Device 210. As another embodiment of the present invention, the current position can automatically be detected by the method so-called ‘global positioning system’ or ‘GPS’ as illustrated in FIGS. 20a through 26 and input the current data therefrom. After the process of inputting the current data is completed, the input destination mode starts and the destination is input by the voice recognition system explained above or by the Input Device 210 (S3), and the voice recognition system is deactivated after the process of inputting the Destination Data is completed by utilizing such system (S4).

[0346] FIG. 68 illustrates the sequence of the input current position mode described in S2 of FIG. 67. When analog audio data is input from Microphone 215 (FIG. 1) (S1), such data is converted into digital audio data by A/D 213 (FIG. 1) (S2). The digital audio data is processed by Sound Processor 205 (FIG. 1) to retrieve text and numeric data therefrom (S3). The retrieved data is displayed on LCD 201 (FIG. 1) (S4). The data can be corrected by repeating the sequence of S1 through S4 until the correct data is displayed (S5). If the correct data is displayed, such data is registered as current position data (S6). As stated above, the current position data can be input manually by Input Device 210 (FIG. 1) and/or can be automatically input by utilizing the method so-called ‘global positioning system’ or ‘GPS’ as described hereinbefore.

[0347] FIG. 69 illustrates the sequence of the input destination mode described in S3 of FIG. 67. When analog audio data is input from Microphone 215 (FIG. 1) (S1), such data is converted into digital audio data by A/D 213 (FIG. 1) (S2). The digital audio data is processed by Sound Processor 205 (FIG. 1) to retrieve text and numeric data therefrom (S3). The retrieved data is displayed on LCD 201 (FIG. 1) (S4). The data can be corrected by repeating the sequence of S1 through S4 until the correct data is displayed on LCD 201 (S5). If the correct data is displayed, such data is registered as Destination Data (S6).

[0348] FIG. 70 illustrates the sequence of displaying the shortest route from the current position to the destination. CPU 211 (FIG. 1) retrieves both the current position data and the Destination Data which are input by the method described in FIGS. 67 through 69 from Area 277 (FIG. 65) of RAM 206 (FIG. 1). By utilizing the location data of streets, bridges, traffic lights and other relevant data, CPU 211 calculates the shortest route to the destination (S1). CPU 211 then retrieves the relevant two-dimensional map data which should be displayed on LCD 201 from Area 275 (FIG. 65) of RAM 206 (S2).

[0349] As another embodiment of the present invention, by way of utilizing the location data stored in Area 277, CPU 211 may produce a three-dimensional map by composing the three dimensional objects (by method so-called ‘texture mapping’ as described above) which are stored in Area 276 (FIG. 65) of RAM 206. The two-dimensional map and/or the three dimensional map is displayed on LCD 201 (FIG. 1) (S3).

[0350] As another embodiment of the present invention, the attribution data stored in Area 295 (FIG. 65) of RAM 206 may be utilized. Namely if any road block, traffic accident, road construction, and/or traffic jam is included in the shortest route calculated by the method mentioned above, CPU 211 (FIG. 1) calculates the second shortest route to the destination. If the second shortest route still includes road block, traffic accident, road construction, and/or traffic jam, CPU 211 calculates the third shortest route to the destination. CPU 211 calculates repeatedly until the calculated route does not include any road block, traffic accident, road construction, and/or traffic jam. The shortest route to the destination is highlighted by a significant color (such as red) to enable the user of Communication Device 200 to easily recognize such route on LCD 201 (FIG. 1).

[0351] As another embodiment of the present invention, an image which is similar to the one which is observed by the user in the real world may be displayed on LCD 201 (FIG. 1) by utilizing the three-dimensional object data. In order to produce such image, CPU 211 (FIG. 1) identifies the present location and retrieves the corresponding location data from Area 277 (FIG. 65) of RAM 206. Then CPU 211 retrieves a plurality of object data which correspond to such location data from Area 276 (FIG. 65) of RAM 206 and displays a plurality of objects on LCD 201 based on such object data in a manner the user of Communication Device 200 may observe from the current location.

[0352] FIG. 71 illustrates the sequence of updating the shortest route to the destination while Communication Device 200 is moving. By way of periodically and automatically inputting the current position by the method so-called ‘global positioning system’ or ‘GPS’ as described hereinbefore, the current position is continuously updated (S1). By utilizing the location data of streets and traffic lights and other relevant data, CPU 211 (FIG. 1) recalculates the shortest route to the destination (S2). CPU 211 then retrieves the relevant two-dimensional map data which should be displayed on LCD 201 from Area 275 (FIG. 65) of RAM 206 (S3). Instead, by way of utilizing the location data stored in Area 277 (FIG. 65), CPU 211 may produce a three-dimensional map by composing the three dimensional objects by method so-called ‘texture mapping’ which are stored in Area 276 (FIG. 65) of RAM 206. The two-dimensional map and/or the three-dimensional map is displayed on LCD 201 (FIG. 1) (S4). The shortest route to the destination is re-highlighted by a significant color (such as red) to enable the user of Communication Device 200 to easily recognize the updated route on LCD 201.

[0353] FIG. 72 illustrates the method of finding the shortest location of the desired facility, such as restaurant, hotel, gas station, etc. The voice recognition system is activated in the manner described in FIG. 67 (S1). By way of utilizing the voice recognition system, a certain type of facility is selected from the options displayed on LCD 201 (FIG. 1). The prepared options can be a) restaurant, b) lodge, and c) gas station (S2). Once one of the options is selected, CPU 211 (FIG. 1) calculates and inputs the current position by the method described in FIG. 68 and/or FIG. 71 (S3). From the data selected in S2, CPU 211 scans Area 277 (FIG. 65) of RAM 206 and searches the location of the facilities of the selected category (such as restaurant) which is the closest to the current position (S4). CPU 211 then retrieves the relevant two-dimensional map data which should be displayed on LCD 201 from Area 275 of RAM 206 (FIG. 65) (S5). Instead, by way of utilizing the location data stored in 277 (FIG. 65), CPU 211 may produce a three-dimensional map by composing the three dimensional objects by method so-called ‘texture mapping’ which are stored in Area 276 (FIG. 65) of RAM 206. The two-dimensional map and/or the three dimensional map is displayed on LCD 201 (FIG. 1) (S6). The shortest route to the destination is re-highlighted by a significant color (such as red) to enable the user of Communication Device 200 to easily recognize the updated route on LCD 201. The voice recognition system is deactivated thereafter (S7).

[0354] FIG. 73 illustrates the method of displaying the time and distance to the destination. As illustrated in FIG. 73, CPU 211 (FIG. 1) calculates the current position wherein the source data can be input from the method described in FIG. 68 and/or FIG. 71 (S1). The distance is calculated from the method described in FIG. 70 (S2). The speed is calculated from the distance which Communication Device 200 has proceeded within specific period of time (S3). The distance to the destination and the time left are displayed on LCD 201 (FIG. 1) (S4 and S5).

[0355] FIG. 74 illustrates the method of warning and giving instructions when the user of Communication Device 200 deviates from the correct route. By way of periodically and automatically inputting the current position by the method so-called ‘global positioning system’ or ‘GPS’ as described hereinbefore, the current position is continuously updated (S1). If the current position deviates from the correct route (S2), a warning is given from Speaker 216 (FIG. 1) and/or on LCD 201 (FIG. 1) (S3). The method described in FIG. 74 is repeated for a certain period of time. If the deviation still exists after such period of time has passed, CPU 211 (FIG. 1) initiates the sequence described in FIG. 70 and calculates the shortest route to the destination and display it on LCD 201. The details of such sequence is as same as the one explained in FIG. 70.

[0356] FIG. 74a illustrates the overall operation of Communication Device 200 regarding the navigation system and the communication system. When Communication Device 200 receives data from Antenna 218 (FIG. 1) (S1), CPU 211 (FIG. 1) determines whether the data is navigation data, i.e., data necessary to operate the navigation system (S2). If the data received is a navigation data, the navigation system described in FIGS. 67 through 74 is performed (S3). On the other hand, if the data received is a communication data (S4), the communication system, i.e., the system necessary for wireless communication which is mainly described in FIG. 1 is performed (S5).

The activation signal is sent to both Emergency Center EC and Communication Device 200. In lieu of Airbag 838 any equipment may be used so long as such equipment prevents from or minimizes physical injuries of the persons in Automobile 835.

[0386] FIG. 87 illustrates the overall process of the automatic emergency calling system. Detector 837 (FIG. 86) periodically checks the status of Activator 840 (FIG. 86) (S1). If the Activator 840 is activated (S2), Detector 837 transmits an emergency signal via Transmitter 836 in a wireless fashion (S3a). The emergency signal is transferred via Network NT and received by Emergency Center EC (FIG. 86) and by Communication Device 200 in a wireless fashion (S3b).

[0387] As another embodiment of the present invention, the power of Detector 837 (FIG. 86) may be usually turned off, and Activator 840 (FIG. 86) may turn on the power of Detector 837 by the activation of Activator 840 thereby enabling Detector 837 to send the emergency signal to both Emergency Center EC (FIG. 86) and to Communication Device 200 as described above.

[0388] This invention is also applicable to any carriers including airplanes, space shuttles, ships, motor cycles and trains.

[0389] Having thus described a presently preferred embodiment of the present invention, it will not be appreciated that the aspects of the invention have been fully achieved, and it will be understood by those skilled in the art that many changes in construction and circuitry and widely differing embodiments and applications of the invention will suggest themselves without departing from the spirit and scope of the present invention. The disclosures and the description herein are intended to be illustrative and are not in any sense limiting of the invention, more preferably defined in scope by the following claims.
