    Abstract: A load control system provides for automatically controlling a position of a motorized window treatment to control the amount of sunlight entering a space of a building through a window located in a façade of the building in order to control a sunlight penetration distance within the space and minimize occupant distractions. The load control system automatically generates a timeclock schedule having a number of timeclock events for controlling the position of the motorized window treatment during the present day. A user is able to select a desired maximum sunlight penetration distance for the space and a minimum time period that may occur between any two consecutive timeclock events. In addition, a maximum number of movements that may occur during the timeclock schedule may also be entered. The load control system uses these inputs to determine event times and corresponding positions of the motorized window treatment for each timeclock event of the timeclock schedule.

Furthermore, at least one coil is located between two stator pole pieces. The armature is enclosed by the stator in the radial direction and has a permanent magnet magnetized parallel to the stator which is disposed between two armature pole pieces. As a result of the reluctance forces, the armature occupies stable idle positions inside the stator in which the stator pole pieces lie opposite the armature pole pieces. By energizing the coils with a short current pulse, the armature can be displaced inside the stator between the different stable idle positions.

The raindrop sensor outputs signals when raindrop collected by the wiper blade passes above the raindrop sensor in a reciprocating wiping operation. The controller calculates the prohibition period of a second reciprocating wiping operation based on the signals of a first reciprocating wiping operation.

  • Patent number: 7960933
    Abstract: A P-range side delimiting position of a movable range of a range change mechanism is learned by rotating a motor to a corresponding rotational position, which corresponds to the P-range side delimiting position. A climb correction amount is set for a learning value of the P-range side delimiting position to correct the learning value of the P-range side delimiting position in view of presence of a relatively small angle of rotation of the motor beyond the corresponding rotational position, which corresponds to the P-range side delimiting position. The climb correction amount is set according to motor temperature information, which is one of a temperature of the motor and a temperature that relates to the temperature of the motor.

  • Patent number: 7932690
    Abstract: A system and associated method for preventing damage to an adjacent wall surface of an electrically operated bed that utilizes a normally closed/momentarily open switch assembly attached to the bed frame at a location such that when the bed fame is maneuvered toward an adjacent wall surface, a head of the switch contacts the wall surface before any other part of the bed frame or a proximity sensor switch is activated when the switch head is in the prescribed range from the wall surface. The push button switch is in electrical communication with the bed frame operational circuitry. When the switch activated from its depression from thw all surface contact or its proximity to the wall surface, the electrical circuitry in the system circuitry is interrupted thereby stopping the operation of the bed frame from being maneuvered and preventing damage to the wall surface.

    Abstract: A linear electro-mechanical actuator comprises a housing with a reversible DC-motor (1), which through a transmission (2) can move an activation element (5) between two end positions. The activation element (5) will in the two end positions cause the electrical end stop switches (17, 25) to be activated for interrupting the current for the DC motor (1) in the end positions of the activation element (5) for running the motor (1) in one direction. Parallel to the end stop switches (17, 25), an extra set of switches (21, 23) are incorporated for determining in which end position the activation element (5) is located.

  • Patent number: 7843153
    Abstract: A control system for controlling an adjustment device which is operated by electric motor in a motor vehicle includes an indirect anti-trapping system for detecting a trapping situation between an adjustment element, which is moved by the adjustment device in an adjustment movement along an adjustment path, and a vehicle element. The anti-trapping system stops or reverses the adjustment movement of the adjustment element if a defined threshold value for a mechanical running parameter—which results from the adjustment movement is exceeded. The anti-trapping system operates with an analysis unit for analyzing the adjustment movement of the adjustment element, wherein the control system is configured and embodied in such a way that by means of the analysis unit, in an analysis mode, the running parameters of the adjustment device can be checked for mechanical functional faults of the adjustment device.

  • Patent number: 7816878
    Abstract: A system and method for coordinating movement of a powered sliding door module and an access ramp for a vehicle. A system control board communicates with a current detector that can detect current on the power wires for the sliding door's motor. The current detector signals the system control board when it detects current and the system control board determines whether the ramp is stowed or deployed. If the ramp is deployed, the system control board stops and reverses the door so that the door remains open. The system control board then stows the ramp and closes the door. If the ramp is stowed, the system control board waits for the current in the door motor to return to zero and then determines if the door is completely open. If the door is not completely open the system control board does nothing. If the door is completely open, the system control board deploys the ramp.
