The transceiver communicates with an electronic device located external to the transceiver using a Bluetooth communications standard.

Abstract: A method for compensating for frequency shifts during transmission of an RF control signal includes receiving a request to enter a transmission mode from a user. A carrier signal having a frequency is generated and the frequency of the carrier signal is measured. The measured frequency of the carrier signal is compared to a desired frequency to determine if there is a difference between the measured frequency and the desired frequency. If there is a difference, it is determined if data is being modulated on the carrier signal. If data is not being modulated on the carrier signal, a correction is applied to the carrier signal frequency.

Abstract: A transmitter for transmitting an RF control signal to a remote system includes a user input device, a memory and a transmitter circuit. The memory includes control data associated with the remote device. The control data includes a first frequency and a second frequency. The transmitter circuit is coupled to the user input device and memory. In response to a single user input, the transmitter circuit generates a rolling code signal, transmits the rolling code signal at the first frequency for a predetermined amount of time, and, upon expiration of the predetermined about of time, transmits the rolling code signal at the second frequency.

Abstract: A wireless control system is configured to be trainable to control any number of remotely controlled devices. The system can be configured to gather and learn information relating to a signal transmitted by the original transmitter in a manner that is blind to a user of the system. The system can be designed to learn signals automatically such that fewer steps are necessary for a user to train the system to control a particular remotely controlled device. The system can train to remotely controlled devices in this manner with little or no user action required.

Abstract: A method for correcting a vehicle compass measurement for an interfering magnetic field generated by a vehicle accessory, where the interfering magnetic field has an intensity sufficient to cause a compass measurement error, includes monitoring the operation of the vehicle accessory and detecting a characteristic of operation of the vehicle accessory. A measurement or timing signal is then generated based on the characteristic of operation. A magnetic field for direction is measured in response to the measurement signal and an offset or correction value is determined based at least one the measured magnetic field and the characteristic of operation of the vehicle accessory.

Abstract: A method for training a receiver of a remote control system to a trainable transmitter includes receiving a control signal from an original transmitter associated with the remote control system. A first period of time is started in response to receipt of the control signal. During the first period of time, a learn message is received from a trainable transmitter. In response to the learn message, the receiver begins a receiver training mode. During the training mode, a rolling code control signal is received from the trainable transmitter and the trainable transmitter is enrolled by storing an identifier of the trainable transmitter.

Abstract: A method for training a trainable transmitter in a vehicle includes receiving a request to enter a training mode of the trainable transmitter from a user. In response to the request, default mode data is retrieved from a memory and transmitted for a predetermined time. Upon expiration of the predetermined time, the trainable transmitter begins a training mode.
