  • Patent number: 9177430
    Abstract: A system includes a translator device that is configured to receive, using a pre-programmed native mode of operation, a first barrier actuation code transmitted by a transmitter according to a first code format. The translator device then analyzes the first barrier actuation code and verifies that it is a valid code. When a valid code, the translator device saves the information contained in the code, and creates a second barrier actuation code at least in part from information contained in the first actuation code and transmits the second barrier actuation code according to the second code format, which is different from the first code format. A barrier operator is coupled to the translator device and a barrier. The barrier operator has a receiver apparatus and the receiver apparatus receives the second barrier actuation code. The barrier operator determines whether the second barrier actuation code is valid, and when the barrier actuation code is determined to be valid, actuates the barrier.

  • Patent number: 7862209
    Abstract: A barrier movement operator controls movement of a movable barrier. The barrier movement operator includes a head unit, including a chassis, for commanding the movable barrier to perform movable barrier functions. A plurality of closely mounted light emitting elements are fixedly mounted onto the head unit. A heat sink is in thermal communication with the set of light emitting elements and with the chassis of the barrier movement operator to dissipate thermal energy from the set of light emitting elements. A controller is utilized for controlling the head unit to provide power to the set of light emitting elements.

  • Publication number: 20090033460
    Abstract: A system and method are provided that use at least one proximity sensor to illuminate a transmitter such that the transmitter can be seen by the user and/or to activate the transmitter so that the user can interface with the transmitter and send code to a receiver via the transmitter to effect an action, such as the opening or closing of a barrier or garage door. The transmitter can also be deactivated so that the proximity sensor is not continually triggering actions by the transmitter thereby potentially causing unwanted actions by the transmitter.

  • Publication number: 20080083167
    Abstract: A chain guide is provided for a garage door operator that reduces frictional forces on the chain guide as the chain moves along a travel path. The garage door operator includes a chain having a portion engaged with a sprocket, with a motor for electrically powering the rotation of the sprocket to thereby move the chain. A chain guide is provided in the operator, with the chain guide defining a path for movement of the chain. The friction reducing insert is disposed in the channel of the chain guide to capture and engage the chain and reduce frictional forces.
