    摘要： A trainable transceiver for learning and transmitting an activation signal that includes an RF carrier frequency modulated with a code for remotely actuating a device, such as a garage door opener. The trainable transceiver preferably includes a controller, a signal generator, and a dynamically tunable antenna having a variable impedance that may be selectively controlled in accordance with a detector circuit signal. The detector circuit provides a measurement of the transmission power and is also used to vary the applied transmission power of the transceiver in response to operating and environmental parameters.

    摘要： A method of determining the position of a tire on a vehicle using signal pulses is described. The method includes receiving a plurality of signal pulses from a transmitter associated with the tire in the time the tire completes approximately one rotation, providing at least one predetermined signal pattern associated with a unique tire position on the vehicle, and comparing the plurality of signal pulses to the predetermined signal pattern to determine the position of the tire on the vehicle.
