Garage door opener with remote safety sensors
First Claim
1. A method of operating a garage door opening system including a control circuit and a motor, said garage door opening system reducing depletion of an external energy source by including means for detecting obstructions in a path of a garage door that are selectively switchable from a first state, wherein said detection means does not detect obstructions and consumes minimal energy and a second state, wherein said detection means detects obstructions, comprising steps of:
- activating said control circuit to provide an impetus to start said motor moving said garage door;
sensing said garage door motion and providing a signal to switch said detection means from said first state to said second state; and
transmitting a control signal from said detecting means to said control circuit at intervals when said detection means is in said second state and no obstructions are detected.

Abstract
A wireless safety system for a garage door opener adapted for use at least in part with an independent energy source is provided. The wireless safety system includes a control circuit for controlling movement of the garage door. An activation member provides an input to the control circuit to initiate motion of the garage door. A detecting member detects whether an obstruction is provided in the path of the garage door. The detecting member includes a first state, wherein the detection member does not detect obstructions and consumes minimal energy, and a second state wherein the detection member detects obstructions. The detection member is selectively switchable between the first state (dormant) and the second state (active) by the control circuit.
