Abstract:
A low power consumption RF receiver system that is adapted for receiving and shaping transmitted digital data signals into a digital data stream for processing by a microprocessor is provided. The receiver system comprises an integrated circuit, which includes a data slicer adapted to accept the received digital data signals, shape the signals into a digital data stream, and pass the digital data stream to the microprocessor. The integrated circuit further includes a peak detector adapted to sense ambient circuit noise when digital data signals are not present, develop a voltage reference signal representative of the peak value of the ambient circuit noise, and pass the voltage reference signal to the data slicer. The receiver system further includes a support circuit between the peak detector and the data slicer that has a voltage divider and a charge capacitor that is adapted to accept the voltage reference signal and produce a clamping reference for the data slicer thereby preventing the data slicer from responding to ambient circuit noise and passing false digital data streams to the microprocessor.
Abstract:
An IG key monitor sends out an anti-theft instruction to a GAIN switching part, in case that an IG key SW (ignition key switch) was turned to an OFF state. The GAIN switching part receives the anti-theft instruction from the IG key monitor, and then, switches detection sensitivity of an acceleration sensor to second detection sensitivity (which is detection sensitivity available for inclination judgment of a vehicle, and for example, is approximately null2 G). An inclination judgment part judges whether or not a vehicle is inclined on the basis of a detection result of the acceleration sensor whose detection sensitivity was switched as described above, and outputs an anti-theft alarm through an alarm part, in case that an output of the acceleration sensor exceeds 0.1 G.
Abstract:
A remote control vehicle security system includes a light emitter that is mounted on a vehicle. A processor for selectively turning the light on or off is electrically coupled to the light emitter. A power supply is electrically coupled to the processor. A cellular receiver for receiving cellular transmissions is operationally coupled to the processor. The processor turns on the light when the processor receives a signal from the cellular receiver.
Abstract:
A vehicle anti-carjacking and theft prevention device incorporating a disabling system for terminating operation of a vehicle whether or not the owner is present thus preventing the theft and/or hijacking of the motor vehicle. The system is passive and always activated when the vehicle is started whether by key or if it is hot-wired. A nondescript hidden touch sensor, in a location selected by the owner during installation, deactivates the system after ignition, which allows the vehicle to be driven normally. An LED light will signal operator that normal driving operation has been attained. If the touch sensor is not touched by the operator after starting the engine, in the time allowed by the manufacturer, then the system will cut the operation of the fuel pump thereby disabling the vehicle within the factory specified distance. The vehicle cannot be restarted unless it is reset. Thereby the system has a hidden reset jack/button for normal operation of the vehicle to be regained. The system also has a hidden valet plug which bypasses the disabling system as long as the plug stays inserted to avoid disclosure or explanations to those parking the vehicle. The system will automatically rearm itself every time the vehicle is turned off. With respect to the unit itself, the nondescript housing contains and protects all the electrical components and is in turn directly wired for each function.
Abstract:
An on-board unit for a vehicle is disclosed. The unit includes a primary communication system, the primary communication system being adapted to communicate with a remote location, and being further adapted to detect a stolen condition or receive an indication of a stolen condition. The unit also includes a process for determining whether communication with a central location can be effected. A secondary communication system is provided, the secondary communication system transmitting a signal including an identification of the on-board unit when communication with the central location cannot be effected. This signal is received by a receiver, which is in direct or indirect communication with the central location, so that the central location can take the appropriate steps to recover the vehicle which includes the on-board unit that is emitting the signal.
Abstract:
The present invention was achieved in order to provide an antitheft device, whereby a person who attempts to commit a theft of a vehicle can be captured, having an improved crime prevention performance to thefts of vehicles, electrical equipment mounted on vehicles, money and articles left inside vehicles and the like, comprising an expansible body system to expand an expansible body for blocking the motion of an intruder in a prescribed space inside a vehicle, which emits a substance to be a base of foaming polystyrene inside the vehicle and applies steam to the substance so that foaming polystyrene blocks the motion of an intruder, when the presence of the intruder inside the vehicle is detected.
Abstract:
A vehicle light controller that facilitates recognition of a vehicle. The controller includes a portable device having a communication function. A lighting device is arranged in the vehicle and has a vehicle entering mode and a vehicle exiting mode with changeable lighting patterns. A first controller and a second controller are connected to the lighting device and communicate with the portable device. The first controller illuminates the lighting device in the vehicle entering mode when communication with the portable device is established and changes the lighting pattern of the lighting device in the vehicle entering mode when a first condition is satisfied. The second controller illuminates the lighting device in the vehicle exiting mode when communication with the portable device is established and a second condition is satisfied.
Abstract:
A transmitter assembly includes a sheath, a closing mechanism, and a transmitter for remote activation of a receiver. The transmitter includes at least one actuator and the sheath is configured to facilitate non-actuation of the transmitter. The closing mechanism is connected to the sheath and is configured to maintain the sheath adjacent the at least one actuator when the closing mechanism is activated.
Abstract:
A vehicle security system is for a vehicle having a door lock circuit including a door lock switch, and a door lock controller responsive to the door lock switch. The security system includes a security controller for operating the door lock controller, and a multi-vehicle compatible interface module for interfacing to the door lock circuit of a given vehicle from among a plurality of different vehicles. In particular, the vehicle may include a single-wire door lock circuit having at least one of a lock resistance and an unlock resistance associated with a door switch. The multi-vehicle compatible interface module may include a circuit board carrying at least one variable resistor that is settable to match the lock/unlock resistance and thereby permit the security controller to operate the door lock controller.
Abstract:
A burglarproof and event-recording apparatus for a vehicle comprises at least one camera arranged on the vehicle to surveil an environmental image for the vehicle and store the image to an image-storing and logic-controlling unit until an alarm flag is set to 1 by the image-storing and logic-controlling unit. The apparatus will raise alarm and set the alarm flag to 1 once the vehicle is intruded. At this time, the image is stored in a currently-used memory block of the image-storing and logic-controlling unit and the intrusion condition is formed to the vehicle owner.
