Abstract

A programmable remote control automatically learns characteristics necessary to generate an appliance activation signal. A sensor is positioned proximate to the appliance. A sequence of different activation signals is transmitted. A determination as to which signal activated the appliance is made based on a received sensor signal. Data representing the determined activation scheme is associated with an activation input.

Claims

1. A method for remotely activating a garage door opener, wherein the garage door opener activates to move a garage door between a closed position in which the garage door covers a garage opening and an opened position in which the garage door uncovers the garage opening upon receiving an activation signal based on one of a plurality of radio frequency (RF) fixed code and rolling code activation schemes, the method comprising:

providing a remote control and a sensor on a vehicle;

positioning the vehicle proximate to the garage opening;

transmitting energy from the vehicle toward the garage opening, whereby the energy is reflected by the garage door while the garage door is in the closed position and is unreflected while the garage door is in the opened position such that a change in the reflected energy is indicative of the garage door being moved between the closed and opened positions;

monitoring by the sensor the reflected energy;

transmitting from the remote control to the garage door opener a sequence of different activation signals, each activation signal in the sequence of activation signals based on a respective one of the plurality of RF fixed code and rolling code activation schemes;

transmitting from the sensor to the remote control a sensor signal indicating activation of the garage door opener in response to the sensor detecting a change in the reflected energy;

based on the sensor signal, determining by the remote control which of the plurality of RF fixed code and rolling code activation schemes resulted in the remote control transmitting an activation signal in the sequence of activation signals that activated the garage door opener; and

associating data representing the determined activation scheme with an activation input of the remote control.

2. The method of claim 1 wherein:

transmitting from the remote control to the appliance the sequence of activation signals comprises transmitting the activation signals based on the RF rolling code activation schemes before transmitting the activation signals based on the RF fixed code activation schemes.

3. The method of claim 1 wherein:

transmitting from the remote control to the appliance the sequence of activation signals comprises transmitting, for each of the plurality of RF fixed code activation schemes, activation signals having different fixed code values.

4. The method of claim 1 wherein:

the sensor is remote from the remote control and the sensor signal is a RF sensor signal.

5. A system for remotely activating a garage door opener, wherein the garage door opener activates to move a garage door between a closed position in which the garage door covers a garage opening and an opened position in which the garage door uncovers the garage opening upon receiving an activation signal based on one of a plurality of radio frequency (RF) fixed code and rolling code activation schemes, the system comprising:

a vehicle having a remote control and a sensor;

wherein the vehicle transmits energy toward the garage opening, whereby the energy is reflected by the garage door while the garage door is in the closed position and is unreflected while the garage door is in the opened position such that a change in the reflected energy is indicative of the garage door being moved between the closed and opened positions;

the sensor operative to monitor the reflected energy and to transmit a sensor signal indicating activation of the garage door opener in response to detecting a change in the reflected energy; and

the remote control having a transmitter, memory, and control logic, wherein the control logic is in communication with the sensor, the transmitter, and the memory;

wherein the control logic controls the transmitter to transmit to the garage door opener a sequence of different activation signals each based on a respective one of the plurality of RF fixed code and rolling code activation schemes;

wherein the control logic receives the sensor signal from the sensor and uses the sensor signal to determine which of the plurality of RF fixed code and rolling code activation schemes resulted in the transmitter transmitting an activation signal in the sequence of activation signals that activated the gargage door opener;

wherein the control logic stores data into the memory indicating the determined activation scheme.

6. The system of claim 5 wherein:

the remote control has a user activation input;

wherein the control logic controls the transmitter to transmit an activation signal based on the determined activation scheme stored in the memory upon an assertion of the user activation input.

7. The system of claim 5 wherein:

the control logic controls the transmitter to transmit the activation signals in the sequence of activation signals based on the RF rolling code activation schemes before transmitting the activation signals in the sequence of activation signals based on the RF fixed code activation schemes.

8. The system of claim 5 wherein:

the control logic controls the transmitter to transmit, for each of the plurality of RF fixed code activation schemes, activation signals having different fixed code values.

9. The system of claim 5 wherein:

the sensor transmits the sensor signal as a RF signal.
