摘要： An adjustable speed garage door operator which has a longitudinal rail with a trolley mounted on the rail and connected to a door to open and close it. A chain is connected to the trolley and is mounted on a front idler sprocket and can be selectively mounted on different drive sprockets which have different numbers of teeth so as to vary the speed of the door.

摘要： A movable barrier operator having improved safety and energy efficiency features automatically detects line voltage frequency and uses that information to set a worklight shut-off time. The operator automatically detects the type of door (single panel or segmented) and uses that information to set a maximum speed of door travel. The operator moves the door with a linearly variable speed from start of travel to stop for smooth and quiet performance. The operator provides for full door closure by driving the door into the floor when the DOWN limit is reached and no auto-reverse condition has been detected. The operator provides for user selection of a minimum stop speed for easy starting and stopping of sticky or binding doors.

摘要： A garage door opening and closing apparatus having improved operational safety is disclosed. The apparatus includes a control circuit which responds to a number of input stimuli to generate commands to open and close a garage door as well as to stop garage door movement. Three relays respond to the commands via drive circuitry to actually connect door operating voltages to the windings of a door controlling motor. By redundancies in the operation of the three relays, faults in the operation of those relays result in safe door operating conditions. Additionally, the control circuitry upon issuing a door stop command, performs a test to determine whether or not the door is still moving. If the door is still moving, door up commands are generated by the control circuitry to place the door in a safe position.

摘要： A door actuating system including a keypad type remote transmitter having a keypad for transmitting door open request signals generated by pressing the keys of the keypad and a stored code type remote transmitter, including a code stored in long-term storage for transmitting door open requests including the stored code. A receiver selectively opens the door responsive to the door open requests from both types of remote transmitters. The receiver includes a user settable security switch which inhibits selective door actuation responsive to door open request signals from the stored code type transmitter while permitting selective door actuation responsive to door open request signals from keypad type transmitters.

摘要： A digital radio control system comprising a transmitter and receiver wherein a plurality of two position switches may be set in a transmitter to pick a particular code which will be serially transmitted by the transmitter and in which a plurality of switches in a receiver may be set to a particular code such that if the same code is selected in the receiver as is set in the transmitter the receiver will be energized upon recognition of the code. Such transmitters and receivers are adaptable to many applications, as for example, garage door actuators; and due to the large number of possible code combinations, interference between other control units within radio frequency range will not occur.
