Abstract: In one aspect, a system includes a movable barrier operator configured to open and close a movable barrier; at least one ultra-wideband device associated with the movable barrier operator and electrically configured to receive ultra-wideband radio frequency signals; and a processor operatively connected to the at least one ultra-wideband device and configured to use the ultra-wideband radio signals to determine a status of the movable barrier.

Abstract: Controlling movable barrier movement with respect to selectively overriding a safety system includes determining whether a safety system is in an operation failure or misalignment state, the safety system being configured to detect obstruction in a path of movement of a movable barrier, receiving a state change request for the movable barrier while the safety system is in the operation failure or misalignment state, determining whether a safety override condition exists, and overriding the safety system and actuating the movable barrier if the safety system is in the operation failure or misalignment state and the safety override condition exists.

Abstract: An apparatus having a controller will initiate an obstacle detector alignment mode. An annunciation system of the apparatus effects a first annunciation mode in response to a receiving component of an obstacle detection system receiving a signal transmitted from a transmitting component of the obstacle detection system. The annunciation system effects a second annunciation mode in response to the receiving component of the obstacle detection system not receiving the signal transmitted from the transmitting component of the obstacle detection system.

Abstract: A first movable barrier operator is actuated in order to move a first movable barrier to a first predetermined position via a first movement and according to a first operating characteristic. A second operating characteristic is selected for moving a second movable barrier to a second predetermined position via a second movement. The second operating characteristic is chosen so that the second movement of the second movable barrier to the second predetermined position does not interfere with the first movement of the first movable barrier to the first predetermined position. A second movable barrier operator is actuated to move the second movable barrier to the second predetermined position via the second movement according to the second operating characteristic.

Abstract: A movable barrier that is at least partially counterbalanced by a spring is moved from a first position to a second position while substantially simultaneously monitoring at least one characteristic associated with moving the movable barrier to provide at least one monitored characteristic. The at least one monitored characteristic is compared to a predetermined criterion. When the at least one monitored characteristic does not meet the predetermined criterion, an alarm condition is set to indicate a failure of the spring.

Abstract: A moveable barrier operator is operated in response to a code transmitted from a code transmitter. A learning entering mode is entered at a moveable barrier operator. One of a plurality of functions is selected to be performed at the moveable barrier operator. A transmitter is actuated and a code is received from the transmitter at the operator. A data structure is formed that associates the received code with the selected one of the plurality of functions.
