TL;DR: In this article, a wireless operating system utilizing a multi-functional wall station for a motorized door/gate operator includes an operator ( 50 ) for controlling the movement of a door/gates between various positions.
Abstract: A wireless operating system ( 10 ) utilizing a multi-functional wall station ( 12 ) for a motorized door/gate operator includes an operator ( 50 ) for controlling the movement of a door/gate ( 54 ) between various positions The system has an operator with a receiver ( 56 ) and a wall station transmitter ( 12 ) for transmitting a signal ( 42 ) to the receiver The signal initiates separate operator functions in addition to opening and closing of the door/gate A remote transmitter ( 70 ) may send a remote signal ( 74 ) received by the receiver, wherein the receiver is capable of distinguishing between the wall station signal ( 42 ) and the remote signal ( 74 ) The wall station includes a transmitter programming button ( 24 ), wherein actuation of the transmitter programming button places the wall station transmitter in a learn mode, and wherein subsequent actuation of the remote transmitter positively identifies the remote transmitter for use with the wall station A light ( 66 ) powered by the operator and a light actuation button ( 18 ) provided by the wall station transmitter is included in the system Actuation of the light actuation button ( 18 ) functions to switch the light on or off A pet height button ( 22 ), provided by the wall station transmitter, selectively positions the height of the gate/door ( 54 ) from its fully closed position to allow ingress and egress of a pet A delay-close button ( 20 ) closes the door/gate after a predetermined period of time Actuation of a door installation button ( 28 ) sequences the door/gate and said operator through various operational parameters to establish a door operating profile A keyless entry transmitter ( 80 ) and a second wall station may also control the operator

TL;DR: In this paper, a gate operator for moving a gate between two fixed end positions such as a gate opened position and a gate closed position and minimizing the possibility of impact with a fixed structure at either of these end positions is described.
Abstract: A gate operator for moving a gate between two fixed end positions such as a gate opened position and a gate closed position and minimizing the possibility of impact with a fixed structure at either of these end positions. The operator relies upon measuring the number of electrical pulses or so-called counts representative of a distance between the two fixed end positions. The gate operator includes a controller in which the number of counts are measured between movement from an open position to a closed position, or a closed position to an open position, and the count is automatically readjusted to eliminate any hard contact of the gate at a fixed closed or open position. In one of the important embodiments of the invention, the gate operator utilizes a controlled coasting system. In this case, the gate is driven from one end position toward the other end position by a motor and the motor is de-energized by a preselected number of counts at a coasting position in advance of the end position toward which the gate is moving. If the gate still strikes the end position or overdrives the end position, the operator automatically compensates so that the gate automatically reaches the end position to which the gate is moving and automatically stops.

TL;DR: An automatic gate operator includes an electric drive motor coupled by a drive train to a movable gate, and includes provisions for sensing an actual or impending obstruction or blockage of the movement of the gate by a human, object, or animal as mentioned in this paper.
Abstract: An automatic gate operator includes an electric drive motor coupled by a drive train to a movable gate, and includes provisions for sensing an actual or impending obstruction or blockage of the movement of the gate by a human, object, or animal, for example. In response to such an actual or impending blocking of the gate's movement, the drive motor is shut off and the gate is braked to a stop. Then the gate is reversed to move a short distance away from the actual or impending blockage or obstruction, and is braked again to a stop. Next, the gate is freed from its connection with the drive motor, allowing manual movement of the gate to allow clearance of the actual or impending blockage or obstruction from the path of the gate. This stop-reverse-stop-release sequence of movements for the gate may release any entrapped person or object which may have been contacted by the moving gate. Also, after the gate is released for free movement it can be moved manually. This release of the gate allows an entangled person, object, or animal to free themselves, or to be freed by a bystander, for example. The gate operator also includes a control circuit which senses traffic conditions and responds by incrementing or decrementing a timer which controls a pause interval of the gate in its fully-opened position.

TL;DR: In this article, an automatic gate opening device consisting of two arm members pivotally attached to form a link is presented, one end of the link is fixedly attached to a hinge post supporting the gate.
Abstract: An automatic gate opening device consisting of two arm members pivotally attached to form a link. One end of the link is pivotally attached to one end of a standoff. The second end of the standoff is fixedly attached to a hinge post supporting the gate. The second end of the link is pivotally attached to the gate. An electrically powered linear actuator is pivotally attached to the post arm and gate arm through levers. The solar panel charges a battery which, through a receiver unit, powers the actuator. Gate operator actuates gate with a portable transmitter.

TL;DR: In this paper, the authors describe a learning mode for a gate operator to learn desired acceleration, deceleration, and acceleration profiles for the gate movement in each direction of movement between opened and closed positions.
Abstract: A powered gate operator includes an electric motor coupled by a drive train to a movable gate in order to drive the gate between opened and closed positions. The gate may also be moved manually between these opened and closed positions, or may be moved by powered operation of the gate operator under manual input control of velocity and acceleration of the gate. The gate operator includes a control system with a learning mode allowing a human to move the gate either manually or under powered operation with manual control, and during which the control system learns desired accelerations, deceleration's, pauses, etc., along with start and finish positions for the gate movement in each direction of movement for the gate between opened and closed positions. Thereafter, during powered operation of the gate by the operator the desired movement profile taught by a human to the operator during a learning mode experience is replicated. In the event that no preferred gate movement profile is available to the gate operator from a learning mode experience, it uses a default gate movement profile. Various default profiles of gate movement may be stored in memory and may be selected by an owner of the gate.
