Patent ID: 7207142

Claim:
A method of remotely monitoring and controlling the position of a movable barrier, comprising: coupling a position measuring device to a barrier operator, wherein said position measuring device generates a barrier position signal; moving the movable barrier between limit positions with said barrier operator; detecting a position of the movable barrier between travel limit positions by said position measuring device coupled to said barrier operator; generating a barrier position signal from said position device; providing a representation by a plurality of position indicators via an interface device, said position indicators identifying the movable barrier's position at various positions between two limit positions based upon said barrier position signal; coupling a potentiometer to the movable barrier, wherein said potentiometer generates said barrier position signal; transmitting said barrier position signal to said interface device which performs said first providing step; providing an up/down button on said interface device, wherein actuation of said up/down button transmits an up/down signal to move the movable barrier; and providing a block button on said interface device, wherein actuation of said block button blocks signals received by said barrier operator from any transmitter, other than actuation of said up/down button so as to prevent movement of the movable barrier.
