Abstract
A security alarm device is replicated in a toy vehicle. The security device includes a remote control which also can control vehicle functions. The remote control may control alarm arm and disarm, alarm and vehicle sounds such as arm, disarm, alarm set off, engine revving, tire screeching, motor drive, and vehicle lights. The security alarm device includes an LED which indicates whether the alarm is armed or unarmed, and a motion sensor which sets the alarm off (e.g., emitting a siren sound) when the toy vehicle is moved in its armed state.

Description
Background of the Invention
The invention disclosed herein relates to a toy, such as a toy vehicle, which has a remotely controlled security alarm.
Toy designers seek to provide toys which replicate real life because realistic toys have high play value, and typically, the more realistic the toy, the greater its play value. Among the many toys for which this is evident are toy vehicles. Realism in toy vehicles has been achieved in appearance, sound and function. For example, miniature toy vehicles are sold which seek to replicate in appearance the full scale real life versions down to minute details. Some reduced scale toy vehicles even have functioning parts, such as doors that open, etc. Other reduced scale toys, somewhat larger than miniatures, provide more elaborate functioning parts and/or provide sound effects, while retaining much if not all of the detail of the miniatures. Still other toy vehicles provide functionality and/or sound effects by remote control. See, for example, the following U.S. Pat. Nos. 4,219,962; 4,242,107; 4,325,199; 4,580,994; 4,817,948; 4,946,416; 4,964,837; 5,024,626; 5,045,016; 5,195,920; and 5,306,197.

Description of the Preferred Embodiments
Referring to FIG. 1, a toy vehicle 10 includes the security alarm device 12 represented in FIG. 2. The vehicle 10 includes wheels 14 at least one of which is driven by a motor 16 (FIG. 2) in conventional fashion except for interaction between the alarm device 12 and the motor 16 (via the motor drive 18). The vehicle 10 may include head lights and tail lights 22 and 23, which may also be conventional except for any interaction with the alarm device 12. The alarm device 12 may include an indicator 26 (e.g., a lamp or a light-emitting diode "LED") which indicates whether the alarm device 12 is in an armed state or an unarmed state.
In the preferred embodiment, the alarm device 12 includes a remote control 30 and a receiver 32 (FIG. 2) carried by the vehicle 10 which are wirelessly coupled together. In the preferred embodiment, the remote control 30 includes an infrared transmitter and the receiver 32 is an infrared receiver. However, the remote control 30 may be connected to the toy vehicle by one or more conductors, in which case the receiver 32 may be omitted. Also, the remote control 30 may include a transmitter other than an IR transmitter. e.g., a radio transmitter or an ultrasonic sound transmitter, etc., and the receiver 32 will be compatible with the transmitter.
Referring to FIG. 1, the remote control 30 may control the following alarm and vehicle functions:
alarm arm and disarm (push button switch #1);
engine revving sound (push button switch #2);
motor drive (push button switch #3); and
vehicle lights (push button switch #4).
Referring to FIG. 2, the remote control 30 transmits coded signals to the receiver 32 carried by the vehicle, which detects the transmitted signals and supplies the detected signals to a controller 40. The controller 40 decodes the signals supplied by the receiver 32 and selectively activates the lamp drive 42 which drives the vehicle head lights 22 and the vehicle tail lights 23, the lamp drive 44 which drives the alarm indicator 26, the speaker drive 46 which drives the speaker 48 and the motor drive 18 which drives the motor 16. One or more sensors 50, 51 are coupled to the controller 40 to provide signals representing security violations. In the preferred embodiment, sensor 50 is a motion sensor. Additional sensors such as sensor 51 may be microswitches or magnetic switches which provide a signal to the controller 40 when the switch is activated and/or deactivated representing, for example, opening and closing a door or hood or trunk lid.
The controller 40 is preferably a programmed computer which includes a sound synthesizer, and is programmed to carry out the functions described herein and generate sound signals representing the sounds described herein in response to input signals from the receiver 32 and the sensors 50, 51. Alternatively, a separate sound synthesizer may be provided.
FIG. 3 shows an implementation of the block diagram of FIG. 2. In the remote control 30, the push button switches ##1, 2, 3 and 4 are coupled to a modulator 60, which modulates the drive to transistor 62 differently in response to activation of each of switches ##1, 2, 3 and 4, and thereby modulates the current to the IR emitter 64. The IR emitter 64 emits modulated IR light in accordance with the different current modulation patterns provided by the modulator 60. The modulator 60 may be any conventional modulator and the IR emitter 64 may be any conventional IR emitter such as an IR LED.
In the vehicle 10, an IR receiver 32 detects the modulated IR light emitted by the IR emitter 64 and supplies the detected signal to a demodulator 70, which demodulates and decodes the received signal and provides an output signal on the appropriate output Out 1, Out 2 or Out 3 depending upon the modulated signal received by the IR receiver 32. The outputs Out 1-3 of demodulator 70 are coupled to trigger inputs TG 1-3 of a controller circuit 74. The motion sensor 50 is coupled to a fourth input of the controller circuit 74. An LED alarm indicator 26 is coupled to the STA output of the controller circuit 74, and when lit indicates that the alarm is armed. In the embodiment of FIG. 3, the LED 80 replaces the separate head lights 22 and tail lights 23 of FIG. 2.
The IR receiver 32, the demodulator 70 and the controller circuit 74 may be conventional. In the preferred embodiment, the controller circuit 74 is a Series W528x integrated circuit available from Windbond Electronics Corp. (Republic of China), and includes an ADPCM (adaptive differential pulse-code modulation) voice synthesizer. The controller circuit 74 includes a programmed processor, which may be programmed by one of skill in the art to carry out the functions described herein.
While the invention has been described and illustrated in connection with preferred embodiments, many variations and modifications, as will be apparent to those of skill in the art, may be made without departing from the spirit and scope of the invention. The invention as set forth in the appended clams is thus not limited to the precise details of construction set forth above as such variations and modifications are intended to be included within the spirit and scope of the invention as set forth in the defined claims.
