Abstract:
1. A combined fob having vehicle keyless entry functions and garage door (GD) opener functions, comprising: a receiver adapted to receive a GD activate signal directly from a GD opener; a processor coupled to the receiver and configured to control the operation of the fob; a user operated switch coupled to the processor, wherein the switch is adapted to permit the user to input at least ‘enter GD learn mode’ and ‘GD activate’ commands for the GD opener function and other commands for the keyless entry functions; a transmitter coupled to the processor and configured to send vehicle keyless entry signals to a vehicle and GD activate signals to a GD actuation mechanism in response to user operation of the one or more user operated switches; a memory coupled to the processor, wherein the memory is configured to store signal parameters of the GD activate signal received by the receiver, wherein the parameters are sufficient to allow the transmitter to replicate the GD activate signal under the direction of the processor; wherein in response to an ‘enter GD learn mode’ command input via the one or more user operated switches, the processor is configured to start a timer setting a period during which the receiver can receive a GD activate signal from the GD opener, wherein the received GD activate signal is analyzed to extract its signal parameters which are then stored in the memory thereby completing the learn mode; and wherein the GD activate signal parameters are thereafter retrieved by the processor in response to an ‘GD activate’ command entered by the user into the one or more user operated switches and used to control the transmitter to transmit a replica of the GD activate signal.
