Abstract:
1. A tire monitor comprising an in-tire controller that stores a target inflation pressure representing the pressure to which said tire should be inflated when said tire is at a standard temperature; and a communication link for coupling said in-tire controller to a processor external to said tire, wherein said in-tire controller transmits said target inflation pressure to said external processor when said external processor is connected to said in-tire controller; a sensor array comprising a pressure sensor and a temperature sensor mounted in said tire; and a memory that stores sensor readings including said pressure and temperature values generated by said pressure sensor and temperature sensor, respectively, wherein said in-tire controller causes said temperature and pressure values to be stored in said memory and wherein said in-tire controller transmits said stored pressure and temperature readings to said external processor; and a motion sensor for generating a motion signal when said tire is moving.
