    Abstract: A system controls opening/closing of a power swinging door, e.g., in a vehicle, and includes a rotary actuator, position sensor, and controller. In a controller-executed method, the actuator applies torque to the door in response to control signals. The controller uses a measured raw angular position from the sensor to determine wind- or grade-based external forces acting on the door during opening or closing, and adjusts the actuator torque in response to the external forces. The sensor may be a rotary encoder, with the actuator being an electric motor. Lookup tables contain data relating oscillation to the external forces. The controller may induce door oscillation and to relate oscillation decay to the external forces. An obstacle-based current threshold may be adjusted in response to the external forces.

    Abstract: A foldable panel gate includes an inner panel section and an outer panel section foldable relative to one another between open and closed positions of the gate. An operating linkage controls displacement of the outer panel section relative to the inner panel section as the inner panel section is driven by a suitable drive between the open and closed positions. The linkage includes a pivotal body coupled to the inner panel section, a first connecting link pivotally coupled between the gate post and the pivotal body, and a second connecting link pivotally coupled between the pivotal body and the outer panel section to fold the outer panel section relative to the inner panel section through a range of 180 degrees as the inner panel section is driven through a range of 90 degrees between the open and closed position.

  • Patent number: 8827041
    Abstract: Carrier car door assemblies respectively comprising a carrier car comprising a body, a door, a drive mechanism, a driven mechanism, and a magnetic release mechanism are disclosed herein. The carrier car travels along a track system between teller and customer stations to transport materials there-between. The door is connected to the body and movable between a door-closed position and a door-open position. The drive mechanism is connected to the body and to the driven mechanism so that the drive and driven mechanisms synchronously move between respective door-closed positions and door-open positions. The magnetic release mechanism is connected to the driven mechanism and moves from a magnetically coupled state to a magnetically de-coupled state when a user manually moves the door from the door-open position to the door-closed position. The magnetic release mechanism in the magnetically coupled state synchronously moves with the driven mechanism between door-closed and door-open positions.

  • Patent number: 8827155
    Abstract: An access control gate with a mechanical guide forms one or more access lanes for patrons. A contactless access reader which is connected to a software controlled verification system identifies access right of patrons shortly before the person approaches a gate threshold formed by two motor driven flaps which when closed protrude into the access lane from left and right of the lateral lane boundaries. A verification system activates the flaps when an access right has been granted. Two or more photoelectric barriers define a detection zone behind the gate threshold and detect the passage of patrons through the gate threshold and the exit of the detection zone. The flaps are closed with highest possible speed after the patron has left the detection zone regularly, and are moved with low speed if an irregular passage is detected.

  • Publication number: 20140173988
    Abstract: A system for opening and closing a motor vehicle, the flap is swivalably mounted along one of its edge areas at a stationary structural component part about a horizontal swiveling axis. A first drive device and a second drive device act in parallel to more like flap from a closed position into an open position. The first drive device is a non-self-locking drive device, and the second drive device comprises a cylinder filled with a fluid under pressure. An interior of the second drive device is divided by a piston into a first work chamber and a second work chamber, wherein a piston rod of the piston is guided outward through the first work chamber. A valve arrangement in the piston closes a flow connection between the first work chamber and the second work chamber in a stationary operating state of the flap.

  • Patent number: 8499495
    Abstract: A drive mechanism for a door operator comprises a drive member and a driven member. The drive member is adapted to be operably connected between a motor assembly for rotating the drive member and a door closer assembly rotating with the driven member. The drive member and the driven member both include a protrusion. The driven member protrusion moves in the free space defined by driving surfaces of the drive member protrusion. Rotation of the drive member from a first angular orientation to a second angular orientation causes rotation of the driven member for powered opening of the door. The driven member protrusion moves in the free space without engaging the protrusion surfaces when the door is opened manually and allowed to close.
