Garage door opener with remote safety sensors
First Claim
1. An automatic door opening safety system for operating on a door, said door being moved along a path, comprising:
- means for controlling movement of said door being electrically coupled to a controlling infrared receiver;
means for detecting whether an obstruction is located in said path and providing a signal to indicate that said obstruction has been detected;
said detecting means including a first and a second infrared transmitter and a detection infrared receiver, said first infrared transmitter and said detection infrared receiver cooperating to detect said obstruction, said second infrared transmitter being optically coupled to said controlling infrared receiver and receiving an input from said detection infrared receiver to generate said signal for said controlling infrared receiver.

Abstract
An automatic door opening safety system particularly for use with garage doors is provided. The garage door includes a leading edge that moves from the open position, where the leading edge defines the top of the opening and a closed position, where the leading edge contacts the ground. A controller is provided for controlling movement of the door. An activation member provides an input to the controller to initiate movement of the door. A detection member is provided for detecting obstructions in the path of the garage door. The detection member includes an infrared transmitter for transmitting an infrared signal to the infrared receiver of the controller.

14. An automatic door opening safety system for operating on a door, said door being moved along a path, comprising:
-
means for controlling movement of said door being electrically coupled to an infrared receiver; means for detecting whether an obstruction is located in said path and providing a first signal to indicate no obstruction is detected and a second signal to indicate that said obstruction has been detected; said detecting means including an infrared transmitter, said infrared transmitter being optically coupled to said infrared receiver of said controller means, so that said controller means receives said first signal from said infrared transmitter means when no obstruction is detected, and said controller means receives said second signal when an obstruction is detected; said detection means having a first state wherein said detection means does not detect obstructions and operates at a low power level, and a second state, wherein said detection means does detect said obstruction and operates at a higher power level.

15. An automatic door opening safety system for operating on a door, said door being moved along a path, comprising:
-
means for controlling movement of said door being electrically coupled to a controlling infrared receiver; means for detecting whether an obstruction is located in said path and providing a first signal to indicate no obstruction is detected and a second signal to indicate that said obstruction has been detected; said detecting means including a first infrared transmitter, said first infrared transmitter being optically coupled to said controlling infrared receiver of said controller means, so that said controller means receives said first signal from said first infrared transmitter means when no obstruction is detected, and said controller means receives said second signal when an obstruction is detected; said detection means further including a second infrared transmitter and a detection infrared receiver optically communicating with said second infrared transmitter.
