Abstract:
A movable barrier operator (10) can control a plurality of light sources (12) via corresponding light drivers (11) to effect various lighting schemes in response to facilitating various operating modes and/or operational states of the operator. Preferably such lighting schemes are both selectively assignable by a user to specific modes/states and themselves uniquely definable by a user.
Abstract:
An asymmetrical drive motor and apparatus with the asymmetric drive motor driving a barrier. The asymmetric drive motor drives the barrier at different drive powers according to direction, time of travel, safety requirements or speed. The drive power is controlled by electrically changing the capacitance value for a permanent split capacitor motor.

Abstract:
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.
Abstract:
A system and method for decoupling a barrier from a barrier movement apparatus for the manual operation of the barrier. Advantageously, the decoupling is performed in response to a wireless signal and may be done only when the barrier is determined to be in a safe position.
Abstract:
A system for detecting objects includes a digital image device such as CCD camera to control a defined area for unauthorized intrusions. The digital imaging device views a predetermined pattern positioned across the defined area from the device. A processor periodically compares an image stored in the memory with a digital representation of the predetermined pattern, and a signal is sent to a control unit when the correlation is missing as a result of the object entering field of vision of the digital imaging device and obscuring said predetermined pattern.
