摘要:
A barrier movement operator is having a position sensor in a telescoping barrier control arm is described. A controller, remote from the arm, senses the barrier position to identify limits of barrier travel and to control rate of travel of the barrier between limits. The operator includes both optical and edge sensor obstruction detectors and is responsive to wireless communication for receiving user initiated command signals.

Information regarding electrical components and their use is provided with a foldable information sheet having instructions thereon. The sheet has apertures which fit over the electrical components and information is printed on the sheet in proximity to the electrical component or components to which it applies. A portion of the information sheet may be adhered to a planar surface on which the components are mounted and non-adhered portions of the information sheet may be folded over the components.

In a multiple barrier movement operator environment, one switch module for controlling all of the barrier movement operators. The switch module may be wall mounted for convenience and communicates with the barrier operator either wirelessly or through a wired interface. The switch module controls and operates movement of any barrier singly while controlling the operation of the overhead lights and response inhibit modes of all the barrier operators. A stop button also maybe provided to enable all the barrier operators to discontinue movement of their respective barriers.

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 includes an absolute position detector which provides a unique value for each position of the barrier along its path of travel. The absolute position detector employs multiple binary serial streams and one multiple clock stream. After the first five cycles of the clock stream, the binary streams can be decoded by a processor to produce an absolute position. Every clock edge produces a new absolute position along the path of travel.

A movable barrier operator comprises a pattern generator for projecting a beam across the barrier path; a CCD camera for recording a pattern produced by projected beam across the barrier path; and a controller for sensing when the pattern produced by projected beam is changed by presence of an obstacle, and generating an obstacle detection signal in response thereto. The movable barrier operator is responsive to the obstacle detection signal to control the barrier drive.
摘要:
A movable barrier operator can use (11) a first technique to prevent an excess application of force during controlled movement of a movable barrier (43) and at least a second technique (12) to similarly prevent an excess application of force during such movement. Both techniques can then be utilized to determine (13) when an application of excess force may nevertheless occur and not be reasonably avoided. In one embodiment, two techniques (21 and 22) can be used to detect force as applied during movement of the movable barrier and such information can be used to determine (23) whether applied force is being reliably indicated. In another embodiment, travel limit information (51), travel information (52) and travel history information (53) are utilized to assess whether normal operation of the movable barrier operator should be over-ridden (54) due to a possibly expression of undue force.
摘要:
In a movable object system (10) that makes use of both a maintained count (31) that corresponds to movement of a given object and passpoint events (32) as generated by a corresponding passpoint signal generator (15), count zones (34, 37, 36A, 36B) can be defined for at least one of the passpoint events. Such count zones can be used to aid in determining when significant recalibration of the passpoint event/count value relationships should be undertaken. In a preferred embodiment, such count zones include no more than a single passpoint event.
