  • Power driven venting of a vehicle
    Patent number: 6169379
    Abstract: An obstruction detection apparatus is provided for use in closing a power driven vent, such as a window, that is located in an opening. When the vent includes a first closing edge that moves as the vent is closed and the opening includes a second closing edge that is contacted by the first closing edge when the vent is in a fully closed position, the apparatus includes a detector configured to detect an obstruction at points all along the second closing edge without requiring contact between the obstruction and the vent and to deliver a detection signal when an obstruction is detected. A controller is connected to the detector for receiving the detection signal and delivering a corresponding alarm signal.
    Type: Grant
    Filed: June 4, 1999
    Date of Patent: January 2, 2001
    Assignee: Prospects Corporation

  • Automatic motor vehicle visor system
    Patent number: 4874938
    Abstract: An automatic electrically operated visor or sun blocker system for a vehicle includes a sun blocker, such as a visor (81), that is automatically positioned laterally across the vehicle windshield (1) to selected azimuth (.psi.) directions, depending upon the relative azimuth direction of the sun and is automatically extended downward to selected elevation (.theta.) directions, depending upon the relative elevation direction of the sun, as required to block the sun so that it does not strike the vehicle driver's eyes. Thus, the visor (81) or sun blocker is automatically positioned depending upon the azimuth (.psi.) and elevation (.theta.) angles of the sun direction relative to the driver's eyes. Those angles are detected by photo-responsive elements (61) that produce signals indicative of the azimuth and elevation angles of the sun, that initiate positioning the sun blocker (81) laterally and extending it downward to block the sun so that it does not strike the driver's eyes.
