    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 system for receiving data for training a trainable transmitter used to subsequently transmit a modulated RF signal having the received data includes an antenna, a capacitive detection circuit and a control circuit. The capacitive detection circuit is coupled to the antenna and configured to detect data provided in a control signal of a remote control transmitter used to remotely actuate a device. The control circuit is coupled to the capacitive detection circuit and is configured to store the received data and to generate the RF signal having the received data to be transmitted by the trainable transmitter to actuate the device.
