Abstract:
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. In one embodiment, 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 carrier frequency of a received or transmitted activation signal. In another embodiment, the trainable transceiver preferably includes a phase-locked loop circuit for providing a frequency control voltage to a signal generator to selectively adjust the carrier frequency of the signal generator. In yet another embodiment, the trainable transceiver includes an amplifying circuit for selectively controlling the gain of a modulated radio frequency carrier signal received from the signal generator and for transmitting an amplified output signal to the remotely actuated device. In a further embodiment, the trainable transceiver includes a frequency table including a list of frequencies for remote transmitters known to transmit for only a short duration and the trainable transceiver first reads the short duration frequencies from the frequency table. Some embodiments will include one or more of these various features.
Abstract:
A trainable transceiver provides an integrated trainable transmitter and control system receiver for a vehicle electrical system. The transceiver includes an input circuit and an output circuit coupled to a controller. The transceiver also includes an interface connected between the controller and the vehicle's electrical system. The input circuit which receives RF signals includes an amplitude control for adjusting the reception range of the transceiver. The transceiver also disconnects the output circuit from the antenna in a remote control training mode or a transmitter signal detection mode. The transceiver is manually controlled to enter the remote control training mode and a transmission mode for controlling a remote device. The transceiver automatically enters the transmitter signal detection mode on a periodic basis.

Abstract:
A trainable transmitter for learning the characteristics of a received RF signal and for transmitting a coded RF signal having the learned characteristics to a receiver for remote activation of a device, such as a garage door opener. The trainable transmitter includes a tunable RF circuit and a controller coupled to the RF circuit for selectively tuning the RF circuit during a training sequence. To provide a user with an early indication that a valid RF signal is being received at the initiation of the training sequence, the control circuit quickly sweeps the frequency at which the RF circuit is tuned from the lowest frequency to the highest frequency of a frequency range in which the carrier frequency of a valid RF signal would fall. If a signal is not detected during this initial fast scanning procedure, the training sequence is terminated and the user is so informed.

Abstract:
A wireless communications system and method adapted for use in automotive applications for enabling automatic, high-speed, wireless voice and/or data communications link to be established between a wide variety of external devices and various electronic subsystems of a vehicle. The apparatus includes first and second RF transceivers which are operated in accordance with a communications specification to enable a seamless, automatic communications link to be created when the two RF transceivers come within a pre-determined proximity of one another, for example, within up to 100 meters of one another. Information from one device is then automatically transmitted over the wireless communications link to the other device. In various implementations the apparatus is used to obtain information from a home PC, a work PC, a notebook PC and various other electronic devices, as well as information from the Internet, which is displayed and/or played back for the user by various subsystems of the vehicle while traveling in the vehicle. Other applications involving retail and manufacturing applications are disclosed by which the apparatus is used to facilitate and/or expedite manufacturing processes or retail transactions via one or more high-speed, secure, wireless communications links which are created automatically and seamlessly between the RF transceivers of the apparatus of the invention.
