  • Patent number: 10337230
    Abstract: During opening and closing actions of a window glass, the presence or absence of pinching of a foreign object in a window is determined on the basis of an amount of change in the movement speed of the window glass and a threshold value stored in a storage unit, and a drive direction of a motor is reversed in order to release a foreign object if it is determined that pinching is present. A threshold value update unit updates threshold values for pinching determination on the basis of the amount of change in the movement speed of the window glass for specific ranges of an entire movement range of the window glass. In addition, a threshold value for pinching determination for a range other than the specific ranges is set to be a preset fixed value.

    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.

  • Patent number: 8669878
    Abstract: A carbon monoxide activated garage door opening system including a garage door opening system connected to an existing garage door and a user interface communicatively coupled to the garage door opening system for toggling the garage door between open and closed positions based upon receiving a corresponding user input at the user interface. Such a user interface preferably has a first carbon monoxide detector located therein for detecting an initial carbon monoxide level in the ambient air surrounding the user interface. A second carbon monoxide detector is attached to a rear side of the user interface for confirming whether the initial carbon monoxide level is an unsafe carbon monoxide level. In this manner, upon validating the unsafe carbon monoxide level, the user interface is adapted to automatically override the user input and thereby open the garage door.

  • Patent number: 8635809
    Abstract: The invention specifies an anti-trapping device, comprising a motor for driving a pivotable actuating element of a motor vehicle, a sensor for contactlessly identifying an obstacle in the way of the actuating element with an electrode, which has a plurality of segments for producing an external electrical field with respect to a mating electrode and a control unit. The electrode extends in a radial direction with respect to the pivotable actuating element and is split in the radial direction into the plurality of segments, which can each be evaluated separately for the purpose of generating an interference signal. The control unit is designed to drive the motor as a function of an interference signal from one of the segments. Such an anti-trapping device has particularly high flexibility when driving the pivotable actuating element if an obstacle in the way of the pivotable actuating element has been detected.

  • Patent number: 8390219
    Abstract: A door operator with an electrical back check feature is disclosed. Embodiments of the present invention are realized by a motorized door operator that electrically creates a back check force for an opening door. The door operator simulates the back check normally created by hydraulic means in convention door closers, but without the use of pistons, springs or hydraulic fluid. The door operator includes a motor disposed to operatively connect to a door so that the door will open when the motor moves, and a position sensor to determine a position of the door. A processor is programmed to exert a closing force on the door in the back check region. In some embodiments, the closing force is exerted by injecting a voltage into the electric motor of the door operator.
