Abstract
A vending machine for dispensing power and telecommunications access is disclosed. The vending machine has a switchable power circuit that receives power from a power source and delivers the power to the customer's equipment via a power connector under the control of a central control unit. A customer interested in purchasing power or using the telecommunications access makes a payment into the payment processing unit which forwards the payment information to the central control unit. From time to time the central control unit reports the transaction information to a central computer system via its modem which is connected to a telecommunication channel. Access to the same telecommunication channel or another channel can be made available to the customer via a switchable telecommunications access circuit which is also under the control of the central control unit. The customer connects to the telecommunications channel via the telecommunications access connector. The central control unit provides information on the progress of the vending transaction to the customer via the user interface. The central control unit determines when the transaction is completed by sensing the cessation of power usage via the power usage detection circuit or via customer action at the user interface.

Description
Background of the Invention
1. Field of the Invention
This invention relates generally to the vending of electricity, telecommunications and/or other utilities in public or semi-public places. More specifically, this invention relates to the operation of computers and other electrical and electronic devices while traveling away from home.
2. Discussion of the Related Art
In this era of communications, individuals are increasingly dependent on a variety of electronic devices to receive and send information. This dependency has resulted in a large number of battery-operated devices which allow an individual to stay in touch while traveling. A major limitation in the operation of these devices is battery life. To overcome this limitation, many of these devices can operate on and recharge from an AC power line. However, AC power for this purpose is not readily available in most public and semi-public places including airports, bus terminals, convention centers and restaurants.
Portable computers have become indispensable communications tools that are used to send and receive voice, fax, email and video messages from and to almost any point in the world. These devices access a variety of communication networks via wired, wireless or fiber telecommunications channels. However, computer compatible access to telecommunications channels is also not readily available in public and semi-public places.
Malaspina (U.S. Pat. No. 5,544,784) addresses the battery life issue and tries to solve it by vending recharged batteries. This proposed solution to the problem is complicated by the shapes, sizes, and electrical characteristics of the many batteries on the market.
A more general solution to the problem is found in those parking meters which provide AC power for an engine block heater or battery charger. Wilkinson (U.S. Pat. No. 5,263,565) defines a combination meter that can allocate a payment between an electricity account and a parking space account automatically based upon whether electricity is being used or not. However, his invention is fundamentally a parking meter and he does not provide for vending power without the parking space. Further, there is no protection from the weather as it was not contemplated that the electricity would be useful for another purpose. Furthermore, while this invention does provide for credit card payments, it does not provide for a telecommunications link for payment or other information.
Ng et al. (U.S. Pat. No. 5,103,957) defines a microprocessor-based parking meter without any power vending capability or ability to accept credit card payments. This invention includes a wireless communications interface for communications between the microprocessor and an external device. Like Wilkinson, Ng is based upon the concept of renting a parking space. The communications interface is intended to connect to a portable computer that is used to change rates within the meter.
Other combination meters have been defined for the purpose of charging electric vehicles. These meters require specific means for connecting to the vehicle, specific means of charging the vehicles batteries and/or specific means for measuring/metering the power consumed. Most importantly, these combination meters rent space for a vehicle so that the fee charged is for parking space rental and for electricity. Additionally, none of these meters is designed to operate a computer.
Some vending machines have also been defined for the purpose of charging electric vehicles. Like the combination meters, these vending machines require specific means for connecting to the vehicle, specific means for charging the vehicle's batteries, and/or specific means for measuring/metering the power consumed. Most importantly, these machines incorporate battery charging circuitry and are only capable of charging batteries, not operating customer equipment such as computers.
Some telecommunications channels that are accessible in public places may come with a communications instrument such as a payphone or pay TV. Some of these payphones used in conjunction with a telecommunications channel have an RJ11 receptacle that is intended to connect special accessories for the physically impaired and which might be able to be used for a computer connection. However, these payphone installations do not provide AC power to operate an accessory or a computer and are limited to providing access to the telephone network line connected to the payphone. These payphones cannot and do not provide fiber, cable or other types of communications channel access. Further these payphones that do accept credit cards as a means of payment still require the central office to process the transaction before the phone can be used.
Summary of the Invention
An object of this invention is to provide access to electrical power, a telecommunications channel or channels and/or other utilities or services for a fee. The customer determines the method of payment, the length of time of access and which of the utilities or services to utilize. The fee is based upon the length of time of access and which utilities or services are accessed.
This invention provides access to one or more utilities after the customer provides payment in electronic form (e.g. credit card, debit card, smart card) or, optionally, currency. The customer selects which utilities or services he requires, typically by just connecting to the appropriate connector. The transaction then begins when some form of payment is received. The transaction ends when the customer disconnects from all of the connectors or otherwise indicates that he is finished. The microprocessor controls the vending process and records the transaction information in retentive memory.
This microprocessor also communicates with the customer via a user interface to provide details on the progress of the transaction. Periodically, this microprocessor is called by a central computer system over a telecommunication channel and may be requested to call back to the central computer. This vending device then calls the central computer and transfers all transaction data, machine status and related information to the central computer. After the data has been transferred to the central computer, the central computer can download any new data, such as new rates, to the vending device. This device does not need to know the rates in effect unless it is accepting payment in currency form or from pre-paid electronic cards. The central computer summarizes the data and processes the payment information and schedules technicians to visit those units that require maintenance or have full coin/currency boxes.
When this invention is used to vend power, the power may come from an internal power source (such as a battery) or one or more external power sources. The power may also pass through a noise and surge protection circuit before it is provided to the customer's equipment. Where more than one power source is available, the customer selects the source he requires by plugging his equipment into the appropriate connector.
Vending telecommunications channel access includes providing access to the high speed data channels that are emerging for computer use as well as the typical telephone networks and cellular lines. These channels include ISDN, T1, T3, cable, SONET and other channels which do not necessarily support credit card or currency based transactions.
Current payphones require central office support to enable a transaction (call). This invention allows the transaction regardless of the capabilities of the central office. In some alternative embodiments of the invention, more than one telecommunications channel will be available to the customer. In such a case, the customer will normally choose the required channel by plugging the equipment into the appropriate connector.
Another object of this invention is to provide a secure area, such as a storage locker, in which a customer can leave their electronic and electrical devices. While the devices are in this secure area, they can recharge their batteries and/or perform autonomous operations such as upload and download messages. In this case, the invention can incorporate a storage locker or other structure with a locking cover.
Another object of this invention is portability. Using an internal power source and wireless telecommunications channels, this invention is not limited to a fixed location. In this configuration, the invention could be used at fairs, outdoor concerts and similar sites where permanent installations are not cost effective.
The invention is envisioned to have, but not limited to, the following applications:
Vending electric power at airports and other public places for any electrical device including, but not limited to, computers, cell phones, pagers and vehicles;
Vending telecommunications channel access at airports and other public places for any communications device including portable computers and special telecommunications devices for the physically impaired;
Vending the combination of power and telecommunications access onboard moving vehicles such as ships, airplanes and buses;
Vending power, communications and other utilities at rental properties, public playgrounds and camp sites;
Vending telecommunications access and electricity or other fuel to vehicles where communications is also useful for vehicle diagnostics or customer communications while refueling or while parked;
Vending power and optionally telecommunications access to electronic equipment locked in storage lockers to allow batteries to recharge and/or to allow autonomous operations such as upload and download messages while the customer is otherwise occupied.

Detailed Description of the Preferred Embodiments
While this specification concludes with claims defining the features on the invention that are regarded as novel, it is believed that the invention will be better understood from a consideration of the following description in conjunction with the drawing figures, in which like reference numerals are carried forward.
Referring now to FIG. 1, a block diagram of a preferred embodiment of a power and telecommunications vending machine 100 for vending power and telecommunications channel access is illustrated. In this vending machine, a microprocessor-based central control unit 106 controls the state of a switchable power circuit 104 and a switchable telecommunications channel access circuit 120. The switchable power circuit 104 switches power on and off at the power connector 108. The switchable power circuit 104 receives input power from an external source that has been processed by the noise and surge protection circuit 102. Similarly, the switchable telecommunications channel access circuit 120 switches the telecommunications channel on and off at the telecommunications channel access connector 122. The switchable telecommunications channel access circuit 120 provides access to an external telecommunications channel that is protected by the noise and surge protection circuit 118.
A vending transaction starts when a customer provides payment at the payment processing unit 114 and connects to the power connector 108 and/or the telecommunications channel access connector 122. Once attached and initiated, the customer can monitor the state of the vending machine and the transaction via the user interface 110.
The transaction ends when the customer disconnects from the power connector 108 and the telecommunications channel access connector 122. The central control unit 106 can detect that the customer has disconnected from the power connector 108 when power usage detection circuit 112 senses that power usage has dropped to zero. The central control unit 106 uses a telecommunications access circuit 116 (such as a modem) to determine when the telecommunications channel is no longer in use. Payment information and transaction length information are retained in retentive memory within the central control unit 106. This memory retains the data in the event of a power failure.
Periodically, a central computer calls the vending machine 100 over the external telecommunications channel. If the telecommunications channel is not busy, the central control unit 106 answers the call using the modem 116 and hangs up to prevent unauthorized access. After hanging up, the central control unit 106 uses the modem 116 to call a pre-programmed number for the central computer and then transfers all transaction and payment information in retentive memory to the central computer.
The fee charged for the transaction is a function of the convenience of the vending machine 100 and the length of time that the customer uses the machine, not on how much power is consumed. As a result, metering of power is not necessary.
In this preferred embodiment, the payment processing unit 114 can accept payment in currency, coin or electronic form. The electronic forms include, but are not limited to, credit cards, debit cards, smart cards and pre-paid cards. Modifications to this embodiment can include devices that only support electronic forms of payment and still other devices that only support currency/coin payment.
The modem 116 is only available to and used by the central control unit 106. In a modification of this embodiment, the modem 116 can also be made available to the customer. For this modification, an extra connector is present which allows the customer to connect from his serial, parallel or other I/O port to the modem 116. This extra connection can also allow high speed communications without forcing the customer to invest in his own expensive or bulky external modem.
It is possible to also have two separate telephone lines connected to his device. One line can be dedicated to the vending device and the other line can be dedicated to the customer. It is possible to provide more than one type of telecommunications channel to the device. For example, if these lines are provided, two lines can be regular phones lines and one can be an ISDN line. In such a situation, the customer would have access to connect their device to an RJ-11 connector or an RJ-45 (ISDN) connector. The remaining phone line could then be dedicated for use by the vending device.
The central control unit 106 is autonomous and controls the operation of the vending machine 100 completely. It typically does not seek preapproval for the transaction to begin. It is possible to modify this and require the central control unit 106 to contact the central computer and obtain payment approval before allowing a transaction to begin.
In FIG. 1, the vending machine 100 only vends power and telecommunications access. In a modification of this embodiment, the machine can be designed to vend one or more additional utilities or services such as natural gas or steam. This device would be used for vending utilities or services to buildings or vehicles.
In another modification of the power and telecommunications vending machine, the power usage detection circuit 112 can be removed. For this device, the user interface 110 includes a push-button which allows the customer to terminate the transaction.
Other modifications of the power and telecommunications access vending machine eliminate one or both of the noise and surge protection circuits 102 and 118 without effecting the function of the machine. It is also possible to have multiple noise and surge protection circuits 102 and 118, one for each power source and one for each telecommunication channel. Those preferred embodiments with multiple power sources are provided in markets where the customer may require different voltage/frequency operation such as 115 Vac, 60 Hz and 220 Vac, 50 Hz.
When multiple power sources are provided, multiple power connectors 108 are also provided. Multiple power connectors 108 can also be provided in certain markets where the customer may require different mechanical forms for the same power such as the many European versions of the 220 Vac, 50 Hz connector. In addition, certain preferred embodiments have an internal power source for use in markets where external power is not available. Similarly, multiple telecommunications channels are provided in certain preferred embodiments for markets where the customer may require different performance choices such as ISDN, cable and standard telephone lines. When multiple telecommunications channels are provided, multiple telecommunications channel access connectors 122 are also provided. Multiple telecommunication channel access connectors 122 are also provided in certain preferred embodiments for markets where the customer may require different mechanical forms for the same telecommunications channel such as the many European equivalents of the RJ11 connector.
Referring now to FIG. 2 where there is illustrated a simplified front view of an operating panel of one implementation of the vending machine 100 described in the preceding paragraphs. The customer sees an operating panel 101 with a user interface 110 comprising two lights referred to as READY and AVAILABLE. The operating panel 101 includes a payment processing unit 114 in the form of a credit card swipe reader; a power connector 108 in the form of a standard duplex, 115 Vac outlet; and a telecommunications channel access connector 122 in the form of a standard RJ11 telephone line connector.
When the customer first approaches the vending machine 100, the READY light is on. The customer swipes his credit card through the credit card reader 114 and plugs his equipment into the appropriate connectors 108 and/or 122. If the central control unit 106 receives valid card information from the credit card reader 114, it 1) turns on power to the duplex outlet 108 via the switchable power circuit 104, 2) turns on telecommunications channel access at the RJ11 connector 122 via the switchable telecommunications channel access circuit 120, 3) turns on the AVAILABLE light 110, and 4) and pulses the READY light 110 slowly for the remainder of the transaction.
If the central control unit 106 does not receive valid data from the payment processing unit 114, it blinks the READY light 110 quickly for several seconds without enabling power or telecommunications channel access this indicates that the customer should swipe the card again or try another card.
When the customer is finished, he merely disconnects from the connectors 108 and 122 and leaves. The central control unit 106 automatically senses this event, records the end of the transaction, turns off the AVAILABLE light 110 and returns the READY light 110 to be on continuously.
In the preferred embodiment of FIG. 2, the user interface consists of two lights which turn on and off in particular patterns to inform the customer as to how the transaction is progressing. In other preferred embodiments, these lights may be replaced or augmented by a video display unit (VDU) which provides more detailed instruction to the customer on vending machine operation and detailed information on the progress of the transaction including the accumulated charges.
In certain embodiments, the VDU could be combined with a keyboard or other push-buttons that would allow the customer to select the language for the display, the connectors to be activated and, optionally, when to terminate the transaction. In the later case, the customer could push a button which would terminate the transaction and the connection, even though he had not disconnected from the connectors.
In still other preferred embodiments, the user interface includes a printer or similar device to provide the customer with a receipt for the transaction.
The central computer can also download new operating instructions, rate information and advertisements that can be displayed at the user interface thereby removing the need for changing a sign posted next to the device that contains this information.
Referring now to FIG. 3 where there is illustrated a block diagram of a preferred embodiment of a power vending machine 200 for vending power only. This vending machine 200 is similar to the vending machine 100 of FIG. 1 and FIG. 2, except that the switchable telecommunications channel access circuit and telecommunications channel access connector are deleted. All other components of this vending machine 200 operate in the same manner as described above. In large implementations of this vending machine 200, the power connector 108 may be a bus bar or power distribution panel for distributing large quantities of power. The fee charged in this transaction is again a function of the convenience of the vending machine 200 and the length of the transaction, not the amount of power consumed.
In this embodiment, the payment processing unit 114 can also accept payment in currency, coin or electronic form. The electronic forms include, but are not limited to, credit cards, debit cards, smart cards and pre-paid cards. Certain preferred embodiments only support electronic forms of payment and still others only support currency/coin payment.
As in FIG. 1, the central control unit 106 is autonomous and controls the operation of the vending machine 200 completely. It can also be modified so that the central control unit 106 must contact the central computer for approval before allowing the transaction to continue and receive power.
In FIG. 3, the vending machine 200 only vends power. It can also be modified so that the machine vends one or more additional utilities or services such as natural gas or steam. This would allow for vending utilities or services to buildings or vehicles.
The power usage detection circuit 112 can also be removed from the vending machine. In this modification, the user interface 110 includes a push-button which allows the customer to terminate the transaction.
Like the first embodiment, the noise and surge protection circuit 102 can be eliminated without effecting the function of the machine.
It is also possible to have multiple noise and surge protection circuits 102, one for each power source. Multiple power sources are provided in markets where the customer may require different voltage/frequency operation such as 115 Vac, 60 Hz and 220 Vac, 50 Hz. When multiple power sources are provided, multiple power connectors 108 are also provided. Multiple power connectors 108 are also provided for markets where the customer may require different mechanical forms for the same power such as the many European versions of the 220 Vac, 50 Hz connector. In addition, it is possible to provide an internal power source for use in markets where external power is not available.
Referring now to FIG. 4 where there is illustrated therein a block diagram of a preferred embodiment of a telecommunications vending machine 300 for vending telecommunications channel access. This embodiment eliminates the power vending components and is particularly useful for connecting computers and other high speed telecommunications equipment to high performance telecommunications channels. All other components operate as described above.
In this preferred embodiment, the payment processing unit 114 can accept payment in currency, coin or electronic form. The electronic forms include, but are not limited to, credit cards, debit cards, smart cards and pre-paid cards. Certain embodiments only support electronic forms of payment and still others only support currency/coin payment.
In the embodiment of FIG. 4, the modem 116 is only available to and used by the central control unit 106. In a modification of this embodiment, the modem 116 is also available to the customer. For this modification, an extra connector is present which allows the customer to connect his serial, parallel or other I/O port to the modem 116. This embodiment is typically used to make high speed communications available without forcing the customer to invest in his own expensive or bulky external modem.
In one version of the device, the central control unit 106 is autonomous and controls the operation of the vending machine 300 completely. In another version, the central control unit 106 must contact a central computer for approval before allowing a transaction to begin.
Like the other embodiments, it is also possible that the machine vends one or more additional utilities or services such a natural gas or steam. This modification is used for vending utilities or services to buildings or vehicles.
It is also possible to modify this embodiment of FIG. 4 to provide power at no charge for equipment that is connected to the machine.
Other possible modifications include elimination of the noise and surge protection circuit 118 providing multiple noise and surge protection circuits 118 and providing multiple telecommunications channel access connectors 122.
FIGS. 1 through 4 show the basic components of the vending machine. A preferred embodiment for the structure of a vending machine 100 includes a work surface or other place to set up a portable computer and related items, optionally a place to sit and optionally a lockable cover to allow the customer to leave their equipment unattended.
Referring now to FIG. 5 where there is illustrated a perspective view of a preferred embodiment of a standard telephone booth style structure 500 for vending power and telecommunications access. In this embodiment, the operating panel 501 is located on the side wall 503 of a vending unit 502. Panel 501 contains electrical receptacles 508, video display unit 510, telecommunications access connectors 522, and card swipe 514. This structure 500, provides a working surface 506 and a seat 504 in each unit. All other components of the vending machine are hidden within the physical structure.
In this embodiment, no payphone or telephone is present. In other embodiments, a telephone or payphone may be present for the customer's use while the vending machine is in use. This would require that the telecommunications channel used by the vending machine be separate from that of the payphone. Still another modification is to have the vending machine and the payphone share the same telecommunications channel.
Referring now to FIG. 6 there is illustrated a perspective view of a preferred embodiment of a kiosk shaped telephone booth style structure 600 for vending power and telecommunications access. In this embodiment, the operating panel 601 is located on the side wall of a vending unit 602. Panel 601 contains electrical receptacles 608, video display unit 610, telecommunications access connectors 622 and card swipe 614. This embodiment provides a working surface 606 and an adjustable seat 604 in each unit. All other components of the vending machine are hidden within the physical structure. In this embodiment, like FIG. 5, no payphone or telephone is present. In other embodiments, a telephone or payphone may be present for the customer's use while the vending machine is in use. This embodiment requires that the telecommunications channel used by the vending machine is separate from that of the payphone. It is also possible to have the vending machine and the payphone share the same telecommunications channel.
In another preferred embodiment of the vending machine in a kiosk or standard telephone booth type structure, a lockable door or locking pull-down or pull-out cover is provided which covers the equipment on the work surface 506/606 and the connections to the operating panel 501/601. This cover mechanism allows the customer to leave their equipment operating while they are otherwise occupied. In this modification, the cover can be unlocked by a key that comes with the cover or unlocked by the same credit card that is paying for the transaction.
Referring now to FIG. 7 there is illustrated a perspective view of a preferred embodiment of a storage locker 700 for vending power and telecommunications access. In this embodiment the power connectors 708 and the telecommunications channel access connectors 722 are located on the back wall of an individual storage unit 702. The payment processing unit 714 and the user interface 110 are located at the door to the unit or can otherwise be external to the storage area. All other components are hidden within the physical structure. In this embodiment, the credit card used to pay for the transaction is also used as the key to the storage unit, while another embodiment uses a standard key lock. Other embodiments of the storage locker delete the telecommunications channel access connectors and related circuits.
An additional modification contemplated for all embodiments is a direct Internet connection that would allow the customer full, high speed Internet access without going through his Internet access provider or on-line service and without the limitations of a dial-up connection, In this case, one of the telecommunication channels available at the vending machine is connected to an Internet router, terminal server or similar function and cannot be used for other communication purposes. The customer's connection to this channel is via an ethernet or other high speed port on his computer using standard Internet software such as, but not limited to, Netscape, Microsoft Explorer, or Mosaic.
In another modification of the device it is possible that, the vending machine 100 is incorporated within the mechanical structure of a telephone or payphone. In this embodiment, the payment processing unit 114 may be used to pay for the vending of power, telecommunications channel access and phone calls. The vending machine can use the telephone line connected to the telephone as the telecommunications channel. In another embodiment the vending machine has at least one telecommunications channel separate from that of the telephone. In these embodiments, the telephone and the vending machine may share the payment processing unit and, optionally, the central control unit and user interface. Furthermore, these embodiments may function autonomously and authorize the transactions themselves, or they may require approval from a central computer or central office, or a combination thereof.
All the preferred embodiments have a telecommunications access circuit 116. When the telecommunications channel is part of the POTS (plain old telephone system) network, this circuit is generally a modem with its own intelligence and interface circuitry. Computer technology is currently changing to reduce the cost and complexity of the modem by moving the intelligence into the central control unit 106 and its program. In the future, the telecommunications access circuit may further evolve to the point where it is a built-in function within the central control unit 106.
In the preferred embodiment depicted in FIG. 2, the power provided to the customer is 115 Vac. Most of the preferred embodiments of the power and telecommunications access vending machine 100, as depicted in FIG. 1, provide at least one AC power connection and no DC power connection. However, there are some embodiments that provide at least one DC power connection without an AC power connection and still others with at least one AC power connection.
All of the embodiments of the power vending machine 200, as depicted in FIG. 3, provide at least one AC power connection. Some of these embodiments also provide at least one DC power connection.
Most of the preferred embodiments of the storage locker 700, as depicted in FIG. 7, provide at least one AC power connection and no DC power connection. However, there are some embodiments that provide at least one DC power connection without an AC power connection and still others with at least one AC power connection.
In certain embodiments of the power and telecommunications access vending machine 100 and the telecommunications vending machine 300, it is necessary for the central control unit 106 to monitor the customer's use of the telecommunications channel to determine how much to charge for the usage or to limit usage to a certain cost level. In these embodiments, the telecommunications access circuit includes circuitry that monitors the routing and address related data at the beginning of a connection. For example, if the telecommunications channel is a POTS line, the central control unit 106 monitors the call to determine the area code or country code to determine that the connection is allowed by the particular installation and, if not, to block the call by turning off the switchable telecommunications channel access circuit. Alternatively, the customer may be charged more for a call to certain locations.
Referring now to FIG. 8, which provides the flowchart for the main program that is executed by the central control unit 106, program execution starts when the vending machine of FIG. 2 is initially turned on. Upon power up, the program:
1. Initializes its internal registers and the telecommunications access circuit 116 so that that circuit is capable of answering incoming calls.
2. Turns off each of the switchable circuits.
3. Performs internal diagnostics to determine vending machine status.
4. Turns on the Ready light and waits for a customer to swipe a payment card at the card reader.
When the program receives new card data, it performs a series of validity checks to determine that the read operation was correct and that the card is one that the vending machine is programmed to accept. If the new card data is not acceptable, the program blinks the Ready light in the fast pattern to indicate to the customer that he should swipe the card again or try a different card. If the new card data is acceptable, the program starts the transaction by recording the transaction start time and turning on the switchable power circuit, the switchable telecommunications channel access circuit and the Available light.
Throughout the transaction, the program blinks the Ready light in the slow pattern and monitors the power usage and telecommunications channel usage. When the customer has stopped using both power and the telecommunications channel for six seconds, the program terminates the transaction by recording the stop time and turning off the switchable power circuit, the switchable telecommunications channel access circuit and the Available light.
When the program has completed all its steps, its returns to a waiting mode for the next customer to swipe his card.
Referring now the FIG. 9, which illustrates a flowchart for the program element that services periodic calls from a central computer, the program is activated by an interrupt generated by the modem when an incoming call is detected. The modem can only detect an incoming call if the telecommunications channel is not in use. The modem, by its nature automatically answers the call and establishes a carrier with the calling computer. The program terminates the connections as soon as it receives two characters from the caller without exchanging any information. If the two characters are not CO (Call Office) the program ignores the call and waits for another incoming call. Otherwise, if a transaction is currently in progress, the program waits for the transaction to be completed.
When the transaction ends or if no transaction is in progress, the program initiates a call to the home office computer using a phone number that is resident within the program. When the home office computer answers and the modems establish a link, the program uploads its identification number, its transaction data and its status. For security, the transaction data is encoded and a checksum is appended to the message. If any errors are indicated by the home office computer, the data is repeated. After the upload is completed, the home office computer downloads any new data or program changes that it has for the vending machine. If any errors are encountered, the information is repeated.
When the download is complete, the program clears the transaction memory and reports the successful completion of this task to the home office computer. Finally this program element terminates the call and waits for the next incoming call.
It is to be understood that although the present invention has been described with regard to preferred embodiments thereof, various other embodiments and variants may occur to those skilled in the art, which are within the scope and spirit of the invention, and such other embodiments and variants are intended to be covered by the following claims.
