Abstract: A power window apparatus is provided for detecting pinching in accordance with the opened/closed position of the window and a state of rotation of a motor, the apparatus having a position sensor which detects a safety-control suspension region of the window and which is an accurate sensor. A spiral guide groove is formed in the inner surface of a housing opposite to a rotational plate which is rotated by an output shaft of a motor which opens/closes a window. A follower which is guided by the spiral guide groove is able to move along a straight guide groove provided for the rotational plate in the radial direction. Terminals in the form of conductive films are provided for a printed circuit board accommodated in the housing. When the rotational plate has been rotated, the follower is guided by the spiral guide groove so as to be moved in the straight guide groove. Thus, a slide member provided for the follower is brought into contact with the terminals so that the terminals are conducted with each other.

Abstract: A power window apparatus for a vehicle, which can open or close a door window by manual operation of a power window switch for energizing either of window-opening and closing relays for rotating a motor in the forward or reverse direction or by automatic operation of the same switch to cause an auto-latching circuit or a control unit to maintain either of the relays in an energized state until the window becomes fully opened or closed. The apparatus is provided with a switch for deenergizing a coil of the window-closing relay by disconnecting the control circuit for latching the energized window-closing relay, thus enabling the opening of the window by manual switch operation whenever an abnormal operation of the auto-latch control system occurs with simultaneous energization of both the window-opening and closing relays in an accident such as the vehicle sinking into water.

Abstract: A rotational speed sensor generates pulses having a period proportional to the speed of a motor, while a pulse period calculator section calculates the period of the pulses. A jamming determination section calculates the motor load based on the pulse period and detects that an object is jammed when the load exceeds a predetermined threshold. Once it has been judged than an object is jammed, a drive control section stops and controls the motor for reverse rotation, thereby releasing the object. A door opening and closing detection section further detects the opening or closing operation of a door which is one disturbance factor. If the door is opened or closed, an inhibit control section inhibits jamming judgment for a predetermined period of time thereafter. This prevents an incorrect judgment due to the opening or closing of the door.

Abstract: The sudden unrolling of an motor driven overhead door is a hazardous occurrence. The invention provides a method of detection and warning of a damaged counterbalance mechanism or other defect in the door lifting assembly. The amperage readings of the drive motor are observed to increase between 5% and 30%, above that of normal operation when the function of the counterbalance assembly or similar drive assembly component is compromised. The method is reduced to practice as a number of alternative electronic circuits which are placed between the line power source and the drive motor. The circuit senses the motor amperage draw and compares the reading with a preset threshold value. Upon the sensed value exceeding the threshold value, a warning is broadcast. This method alerts one of undue strain on a damaged lifting assembly prior to its catastrophic failure.

A timer 14 for resetting time each time the pulse edge in the two-phase pulse arrives is disposed in the MCU 2.

Abstract: An automatic gate operator includes an electric drive motor coupled by a drive train to a movable gate, and includes provision for measuring the coasting distance which the gate moves after shut off of the drive motor. This coasting distance varies both with the weight and momentum of the gate in comparison to frictional drag of the gate hardware, and the drag provided by the gate operator with the drive motor shut off, and also varies in response to a great number of other variables many of which are unpredictable. These other variables include such factors as wind, weather, temperature, wear, adequacy of lubrication, time interval since last operation of the gate operator, and off-level installation of the gate, for example. However, the coasting distance is measured and recorded, and is subsequently used as a predictor of gate coast on subsequent operation of the gate operator in order to coast the gate to a stop precisely at a selected limit position.

Abstract: An automatic, self-adaptive controller for varying the interval between wipes of a windshield wiper arrangement for a vehicle measures current drawn by the windshield wiper arrangement during a forward and return portions of the windshield wiper wipe cycle and calculates an integration of the current over each portion of the windshield wiper wipe cycle to establish forward portion and return portion integration. The magnitude of the portions, which graphically appear as current lobes over time, are indicative of wiper-to-windscreen friction, and hence, wetness. The difference between the forward and return integration is representative of vehicle air speed. The windshield is characterized as wet when the first and second summation values are small, and in that case, a short interval between wipes is established. When the first and second integration values are large, the windshield is deemed to be dry, and a long interval is established between wipes.
