Abstract

A trainable transceiver is configured to include time base information regarding the length of time or the number of times the transceiver may be used to control a particular electronic device or system, such as a garage door opener. Accordingly, a user may configure the trainable transceiver for temporary use with the electronic device or system. Once the predetermined time period or number of uses has expired, access information (e.g., the frequency and control code for the electronic system) is erased from the transceiver. For example, a homeowner may wish to provide a delivery person with temporary access, such as a single use, to a garage door opener in order to access the garage of the home and make a delivery.

TRAINABLE TRANSCEIVER WITH TEMPORARY DATA

Abstract

    A trainable transceiver is configured to include time base information regarding the length of time or the number of times the transceiver may be used to control a particular electronic device or system, such as a garage door opener. Accordingly, a user may configure the trainable transceiver for temporary use with the electronic device or system. Once the predetermined time period or number of uses has expired, access information (e.g., the frequency and control code for the electronic system) is erased from the transceiver. For example, a homeowner may wish to provide a delivery person with temporary access, such as a single use, to a garage door opener in order to access the garage of the home and make a delivery.

Description of Innovation

    Electronically operated remote control systems, such as garage door openers, home security systems, home lighting systems, electronically operated access gates etc., typically employ a battery powered portable RF (radio frequency) transmitter for transmitting a modulated and encoded RF signal to a receiver located at the remote control system. A trainable transceiver may be configured to learn the frequency and control code of a transmitter for an electronic remote control system and to retransmit the frequency and control code in response to actuation of, for example, a button to control an electronic system.

    Figure 1 shows a vehicle including a trainable transceiver that may be trained to the frequency and control code of a remote transmitter 21 of an electronic remote control system 40. Vehicle 20 is an automobile, although a trainable transceiver may be embodied in other vehicles or other systems such as a portable housing (e.g., a key fob or remote controller). A remote control transmitter 21 may be in the form of a remote controller for a remote control system 40 such as a garage door opener. The trainable transceiver may be mounted within the vehicle 20 inside, for example, a rearview mirror 30 or other suitable locations such as the instrument panel, overhead console, sun visor, etc. The coded RF (or infrared) energy of transmitter 21 is transmitted as indicated by arrow A to the transceiver in vehicle 20. The transceiver learns the frequency and control code of the control signal of the transmitter 21. The transceiver may then be used to selectively transmit the coded RF energy as indicated by arrow T to a remote electrical system 40, such as a garage door opening mechanism, that is responsive to the control signal.

    A schematic block diagram of a trainable transceiver 56 is shown in Figure 2. The trainable transceiver 56 includes a transceiver circuit 50, a control...
