摘要:
A barrier operator comprises a current limit portion and a barrier operator portion. The current limit portion is coupled to a mains supply and the barrier operator position is coupled to the mains supply and the current limit portion. The barrier operator portion actuates a movable barrier. The current limit portion regulates electrical current to at least one additional device.

A movable barrier operator system operational component includes an integral display comprising at least one of a numeric display, an alphanumeric display, and a graphics display. The display can comprise an active display or an active interactive display and can further operate in conjunction with adjacent user-input interface opportunities. So configured, numerous user interface events can be highly leveraged to contribute to ease of installation and ease and reliability of use.

A support assembly for a barrier movable between open and closed positions over an opening comprises a track. The track is attached to the wall for guiding movement of the barrier between substantially vertical closed position and a substantially horizontal open position. A jack shaft assembly is attached to the track and to the barrier for movement thereof. A mounting assembly is attached to the track for receiving a drive unit comprising a motor for supplying power to the jack shaft assembly to move the barrier and for limiting rotational movement of the drive unit.

An apparatus and a method for quick mounting of a barrier operator on a ground surface is disclosed. The apparatus includes a mounting frame positioned on the ground and mounting structure extending into the ground surface. Concrete may then be poured into the mounting frame to form an operator support on which the barrier operator is mounted. The mounting structure may be a mounting post received in an excavated portion of the ground, and the mounting post and excavated portion may then be filled with concrete. The concrete in the frame, mounting post, and mounting frame may communicate as to form a unitary mass with the mounting frame and mounting post. The mounting structure may be mounting rods secured directly with the ground. The mounting rods have a spiral flute for driving into and securing with the ground.

One or more optical signals (wherein at least some of a plurality of optical signals are at different angles of travel with respect to one another and are directed towards an area comprising a movable barrier-controlled point of passage) create reflections when striking passageway boundaries as correspond to a given movable barrier. Obstacles in the pathway also give rise to reflections. By determining a time-of-flight for such reflections, one can detect a likely presence of an obstacle in such a pathway. Pursuant to one approach, such time-of-flight information can further provide information regarding a likely size of such an obstacle.

A barrier movement or garage door operator has a jack shaft connected to an output shaft delivering power to move a barrier or garage door between open and closed positions, the jack shaft and output shaft being connected by a coupling. The coupling, jack shaft, and output shaft are fixed relative to each other. The coupling connects the jack shaft and output shaft for rotation around a common axis. The coupling receives a portion of the jack shaft and output shaft for securing the shafts within the coupling by compressing against an outer surface of each shaft. The shafts may be cylindrical, and the compressive force may be distributed around the cylindrical outer surface of the shafts. The coupling may have a portion sized to correspond to respective predetermined diameters or sizes of the shafts.

A packaging system is provided for facilitating transport of a moveable barrier operator. The packaging system comprises a generally rectangular container having a top wall, a bottom wall, a front wall, a rear wall, and two side walls defining an interior compartment. A handle is coupled to the top wall for movement between an extended position and a retracted position within the interior compartment. A wheel mount is coupled to the bottom wall, and at least one wheel is mounted on the wheel mount.
