Filed:

Dec 4, 1995

Appl. No.:

8/566836

Inventors:

Keith R. Cook - Beavercreek OH

Assignee:

ITT Automotive Electrical Systems, Inc. - Auburn Hills MI

International Classification:

B60S 104

US Classification:

134 6

Abstract:

A wiping system and method for wiping a windshield is shown. The wiping system comprises frictional material or a wiper material which is applied directly to either a wiper blade or a windshield in at least one reversal area on the windshield where the wiping blade is driven from a first direction to a second direction which is generally opposite that of the first direction. The wiper material is coated or integrally formed as part of the windshield in the reversal areas to facilitate increasing the friction between an edge of the wiper blade and a surface of the windshield which, in turn, facilitates causing the blade to flip from a first wipe side to a second wipe side, thereby reducing or eliminating "chisel chatter" problems of the past.

International Classification:

F16F 950

US Classification:

267 6421

Abstract:

Pneumatic suspension system for automotive application in which sprung and unsprung masses are supported by variable volume air spring units and incorporating compressor and exhaust valve devices for supplying an exhausting pressurized air from the units to adjust the height between the masses. A Hall effect device effective across a pressure boundary senses the position of a magnet movable within one of the air spring units and reflects relative movement of the sprung and unsprung masses to effect control of the supply and exhaust of air from the units. By axial movement of the Hall device, dead band width can be established to accommodate normal ride motions between sprung and unsprung components. By rotating the Hall device at any axial position, the vehicle bumper height can be selectively increased or decreased.

Assignee:

General Motors Corporation - Detroit MI

International Classification:

F16D 1314

US Classification:

192 78

Abstract:

A power door lock actuator includes a one piece molded and centrifugally expandable brake ring that is held on a drive ring to a motor shaft within a lock lift arm driving cup that is freely pivoted to the shaft. A camming member on the drive ring fits within the brake ring so as to retain it to the shaft, to maintain it in a ready position spaced from the cup when stationary, and so as to jam it into the wall of the cup when turning.

Assignee:

International Classification:

H02P 122

US Classification:

318280

Abstract:

Motor control apparatus is disclosed for a motor driven vehicle power window mechanism including a flexible drive element, such as a drive tape, adapted to drive the window in a predetermined direction by being placed in tension by the motor. The tension of the flexible drive element is relieved by automatically reversing motor direction for a short time when the window reaches the desired position. The reverse motor rotation is accurately controlled to an amount sufficient to relieve drive tension but insufficient to produce unwanted reverse movement of the window by detecting the pulses of the armature ripple current as the successive commutator bars pass the brushes during reverse motor rotation, integrating these pulses and stopping the reverse motor operation when the integrated value reaches a predetermined reference.

Assignee:

ITT Automotive Electrical Systems, Inc. - Auburn Hills MI

International Classification:

H02P 104

US Classification:

318806

Abstract:

A windshield wiper system having variable frequency induction motor control for reducing wipe speed at reversal points includes an induction motor, a wiper and blade assembly operatively connected to the motor, a sensing means for detecting when the position of the wiper and blade assembly is within a preselected range of one of the reversal points, and a motor control responsive to the control signal generated by the sensing means for causing the motor to reduce wipe speed during the preselected range prior to the reversal point to reduce pattern growth, noise, and water expulsion. The sensing means takes the form of a cam or plate operated switch driven by the induction motor. The control signal derived from the cam operated switch is provided as an input to a voltage controlled oscillator, whose variable frequency output is used to vary the frequency of the excitation voltage applied to the windings of the three phase induction motor.

International Classification:

H02P 104

US Classification:

318443

Abstract:

A motor reversing control circuit for a motor vehicle windshield wiper has a motor driven cam with a first lobe defining a park position for the wiper and a second lobe defining, in relation to the first, a wipe angle. A park switch is actuated by either lobe to reverse the output of a flip-flop which controls motor direction. The motor is activated in response to one or more of (a) a main switch, (b) the unactuated park switch and (c) the flip-flop output signalling wiper movement toward the park position. An optional timer effective to delay the motor activation in response to the main switch provides a pause in the park position.
