Abstract:
In a power window device, a DOWN switch has first and second switches in a power window circuit located in a door for a window of a passenger's seat. A normally-closed contact of the first switch and a remote UP terminal of the power window circuit to which an UP signal is applied from a power window circuit provided near the driver's seat are connected. A normally-closed contact of the second switch and a remote DOWN terminal of the power window circuit to which a DOWN signal is applied from the power window circuit are connected. When the DOWN switch is manually operated, a signal supply line to which the UP signal and the DOWN signal are applied and a power supply line to which a power source is connected are electrically disconnected. As a result, the power window device is operable even when the signal supply line is grounded due to submerging in water.
Abstract:
An internal entrapment system for a garage door operator (30), comprising a motor (48) for transferring a garage door (12) between first and second positions; a pulse counter (62) for detecting a speed of the garage door (12) during transfer between first and second positions; a potentiometer (56) for determining a plurality of positional locations of the garage door (12) during transfer between first and second positions separate from said pulse counter (62); and a control circuit (50) for calculating a motor torque value from the speed for each of said plurality of positional locations to compare with a plurality of door profile data points, wherein said control circuit (50) takes corrective action if the difference between the motor torque value for each of said plurality of positional locations and said plurality of door profile data points exceeds a predetermined threshold, and wherein said control circuit (50) updates said plurality of door profile data points to the motor torque values for each respective said plurality of positional locations if the predetermined threshold is not exceeded. In another embodiment both speed and position are detected by a slider element (58) which is connected to the control circuit (50). A closed loop lift cable system (100) may be employed for use with the internal entrapment system. The system (100) utilizes a lift cable (164) connected between a bottom section of the door and a drum mechanism (150) and an upper cable connected between a top section of the door and the drum mechanism (150). A tension device (180, 200) ensures that the door and cables act as one and thus allow closed loop control of the door.
Abstract:
A highly dependable motor drive system capable of driving a motor with certainty even in a submersion accident and preventing overcurrent from flowing to the motor on the occasion of switching the direction of rotation. It is so arranged that, of a first and second relay for rotating the motor in the normal and reverse directions, respectively, in response to operation of associated switches, the first relay is selectively actuated and the second relay is de-energized. As the associated switch is operated, the energization of the coil of the second relay is maintained for a while by the function of a bypass circuit so that the actuation of the second relay is stopped only after actuation of the first relay with a transient motor stand-still time therebetween.

Abstract:
A device, for automatically opening a side window glass synchronously with an expansion of ESPS (electric single point sensing system) air bags, is disclosed. The device includes a window carrier movably engaging with a guide channel, and a regulator motor connected to the carrier by a cable. The device also includes a window glass module provided at the upper portion of the guide channel so as to be selectively operated by a self-diagnosis impact sensor of the air bags in the event of an expansion of the air bags, thus forcibly lowering said carrier along with the side window glass by means of the explosive power in such an expansion.
Abstract:
A circuit is provided to ensure that even when a drive circuit system for a power window is wetted with water due to the entering of water or the condensatin of water, the opening and closing of the power window can be performed without hindrance. Coils of an opening relay and a closing relay are selectively connected at one end thereof to a power source or ground through a control switch and at the other end to the power source or ground through an electronic circuit which has been subjected to a water-proofing treatment. Even if leakage current flows from a high-potential portion of the coils to ground, the leakage current is caught by electric current flowing from the power source. In addition, even if leakage current flows from the power source to a lower-potential portion of the coils, the leakage current flows to ground without passing through the coils. Therefore, the unintended excitation and de-excitation of the coils can be prevented to thereby reliably open and close the power window.
Abstract:
A method is disclosed for selective alteration and control of door movement modes utilizing an apparatus that is primarily non-hydraulic and incorporated with a known mechanism which is functional independently from the apparatus in one mode of operation and which includes a piston for controlling door closing characteristics by selected fluid flow within the mechanism. The apparatus includes a motor driven lead screw having a linearly movable shuttle unit mounted thereon, the shuttle unit being positioned relative to the piston of the mechanism to accommodate nonattached contact with the piston to urge the piston, when the shuttle unit is moved, in a direction that will at least provide selective assistance with door opening in another mode of operation. Operation of the apparatus is controlled by programming of a related controller including non-volatile memory.
Abstract:
A carbon monoxide sensing system is provided including a garage having an automatic door adapted to open only upon the receipt of an activation signal. Further provided is a carbon monoxide sensor positioned within the garage and connected to the automatic door for transmitting the activation signal upon the detection of an amount of carbon monoxide which exceeds a predetermined amount. A light beam detector is adapted to generate the activation signal only upon the detection of vehicle within the garage. Also included is a control mechanism connected between the carbon monoxide sensor, light detection and the door opener for allowing the transmission of the activation signal to the door opener only upon the receipt of the activation signal from the light beam detector.
Abstract:
A vehicle power liftgate cable drive has a cable drive housing. An electric motor with a motor housing and an output shaft is secured to the cable drive housing. A clutch pack with a first clutch driven by the output shaft and a second clutch driven by the first clutch, is mounted in the cable drive housing. One of the clutches in the clutch pack is a one way clutch and the other clutch is an electromechanical clutch. A pinion gear is driven by the second clutch. A driven gear is rotatably journaled on a fixed shaft and driven by the pinion gear. The cable drum is attached to the driven gear. A coil spring has one end fixed to the fixed shaft and its other end attached to the cable drum. The fixed shaft is rotated to preload the coil spring in a direction that tends to wind a cable on the cable drum and then the fixed shaft is fastened to the cable drive housing. A cable is attached to the cable drum and to the liftgate.
Abstract:
In event of a collision accident involving a motor vehicle having electric window regulators and power door locks, automatic and immediate door unlocking and window roll-down occurs to aid in passenger egress and emergency medical personnel access without a critical loss of time which might otherwise result in additional passenger injury and risk for the medical personnel. The electrically regulated windows may also be activated whereby their roll-down may be accomplished by operating an exterior door release handle subsequent to an accident, in lieu of automatic roll-down. Motor vehicles having inside door latch disablement setting devices, such as "child protection locks" are also "unlocked" to enable door release by a passenger from inside of the vehicle to avoid dangerous entrapment of the passenger within the damaged vehicle.
