Abstract: A door operator for a reversibly operable door includes a frame and a carriage movably mounted on the frame and attached to a door for moving the door between open and closed positions. A drive member, specifically a roller chain, extends along the frame and moves the carriage. A drive train is provided within a housing and is connected for moving the drive member, and a control circuit is provided for controlling the drive train to open and close the door. A pair of limit switches is mounted within the housing and connected to the control circuit for stopping the drive train when the door has reached a completed position. A pair of limit cams are adjustably mounted on a limit wheel within the housing and separate from the carriage for engaging the limit switches. The limit wheel, which is separate from the drive member, is connected to the drive train to rotate when the drive train moves the carriage. The placement of limit switches and associated connecting wiring along the frame in the garage ceiling is eliminated. The limit cams can be easily and automatically positioned on the limit wheel by pushing a single switch without any manual movement of the limit switches or of the movable cams that contact the limit switches.

Abstract: A light beam transmitter and receiver are located in or near a door opener enclosure, and fiber optics connect the transmitter and receiver to the sides of the door opening. Lens arrangements are attached to the ends of the optic cables and are mounted near the bottom of the door frame. Thus, the transmitter and receiver do not need to be located near the door which eliminates the need for wiring from the enclosure to the door area and protects the transmitter and detector from physical abuse at the doorway.

Abstract: An enclosure is provided for the installation of a ceiling fan remote control circuit in a ceiling fan. A generally rectangular box encloses the circuit and is installed inside a canopy of a ceiling fan so that it rests above a support conduit and below a mounting plate. The enclosure is compact and inexpensive to manufacture and permits existing fans to be converted to remote control without requiring additional space. No adapters or additional part are needed and the appearance of the fan is not altered.

Abstract: A safety system is disclosed for universal attachment to existing garage door openers. A transmitter of infrared energy transmits a beam laterally of the door opening to detect any obstruction to door closing movement. A safety control circuit is adapted for connection to the main control circuit of the existing garage door opener, the existing push button switch is disconnected from the main control circuit and connected to the new safety control circuit, a flexible cable or cord is connected for actual movement in accordance with movement of the door and is connected to the safety control circuit at a reel on which the cord is wound, and the safety control circuit determines if there is actual door movement and actual door closing movement, as well as being responsive to an obstruction to door closing movement to apply a signal to stop the door and then apply another signal to start the door in its opening movement.

Abstract: A control unit remotely operates several different functions of a gas fireplace. The functions include ignition of a fire, control of flame height, blower control, and damper control. An RF or IR transmitter has several different switches corresponding to desired operations to be performed. Each switch or combination of switches sends different coded signals to a receiver in the control unit. The control unit operates a gas valve and an ignitor to start the fire in response to a start signal. The gas valve is further controlled to vary the height of the flame or extinguish the flame in response to corresponding signals. The blower, damper and other functions can be controlled in response to other signals.

Abstract: A door operation control system has a door opening for moving a door between open and closed positions. A door operator control circuit selectively operates the drive means to move the door between the open and closed positions. An obstruction detection device detects whether there is an obstruction in the path of the door between the open and closed positions and generates a signal in response thereto. The obstruction detection device is connected to the control circuit by wiring to permit operation of the door opener in the absence of a signal from the obstruction detection device and to prevent certain operations of the door opener in the presence of a signal from the obstruction detection device. An error detection circuit detects faults or errors in the wiring and generates a signal to prevent certain operations of the door operator when the faults or errors are detected. The error detection circuit prevents unsafe operation of the door opener if a wiring error has made the obstruction detection device inoperative.
