    摘要: A method of protecting data in a smart card (10) from unauthorized access, the method comprising providing a housing defined by first and second housing portions (12, 13); employing a volatile memory (14) in the smart card for storing the data, and supporting the volatile memory from the first housing portion; providing a power supply (15) in the housing, the power supply maintaining the data in the volatile memory while the power supply is connected to the volatile memory; and connecting the power supply to the volatile memory using a conductor (17) supported by and movable with the second housing portion. A smart card comprising a housing including two opposing major portions that are connected together; an integrated circuit (18) supported in the housing, the integrated circuit including a microprocessor and a random access memory, the random access memory being used to store data; a battery supported in the housing and having first and second terminals, the first terminal being coupled to the integrated circuit; and a conductor coupling the second terminal of the battery to the integrated circuit to complete a circuit, the conductor being supported by the housing such that separation of one of the portions of the housing from the other portion opens the circuit and breaks connection of the battery to the microprocessor so that data held in the random access memory is erased.

    摘要: A system comprising a vehicle on-board computer; and a wireless transponder device coupled to the vehicle on-board computer. The system performs a variety of functions because of its ability to transmit and receive data from other transponders which may be remote from the vehicle or located in the vehicle at a location spaced apart from the system. Remote transponders are spaced apart from the vehicle. The remote transponders can be positioned, for example, at a gas station, toll booth, service center, dealership, parking lot, or along a roadside.

    摘要: A pseudo random number generator comprises a linear feedback shift register switchably operable in a first mode, and in a second mode. In the second mode the shift register consumes more power than in the first mode. The method of generating a pseudo random number comprises: providing a linear feedback shift register; providing an oscillator which generates clock signals used by the linear feedback shift register for shifting; and providing a first power level to the oscillator when a pseudo random number is required, and providing a second power level, lower than the first power level, to the oscillator at other times.
