Abstract:
In combination with a vehicle tire, a transponder for sensing, storing and transmitting vehicle tire condition parameter data comprising:a substrate mountable on a vehicle tire;an integrated circuit chip mounted on the substrate, the integrated circuit chip including a processor, a memory, a receiver means connected to the processor for receiving an interrogation signal from a remote source, and a transmitter means connected to the processor for transmitting a signal containing data representative of the sensed tire condition parameter to a remote source;sensor means, mounted on the substrate, for sensing a tire parameter at predetermined times when electrical power is applied to the sensor means, and for generating an output signal to the processor representative of the sensed tire parameter at each predetermined time;power supply means, mounted on the substrate, for supplying electrical power to the integrated circuit chip and the sensor means; andantenna means, mounted on then substrate and connected to the receiver means and the transmitter means, for communicating an interrogation signal from the remote source to the receiver means and for communicating a signal from the transmitter means to the remote source;the memory responsive to the processor for storing the output signal from the sensor means at the predetermined times.
