摘要:
A windshield wiper system for motor vehicles includes an electric motor which drives at least one wiper during normal wiper operation, too and fro between two reversing positions within a wiping area. When the wiper system has been switched off by means of an operating switch, the wiper is moved to a concealed parking position outside the wiping area. Upon switching on of the wiper system and during normal operation the motor runs in one direction of rotation, but for moving the wipers into the parking position the motor runs in the other direction of rotation. A position switch is changed over by a switching member coupled with a rotating drive member of the electric motor. The position switch, after the operating switch has been switched off, releases a signal for reversing the polarity and in the parking position releases a signal for switching off the electric motor. So that the wiping cycle for entering the parking position begins in the first reversing position adjacent to the parking position and the wiper occupies the first reversing position in the dwell time interval of intermittent operation, the position switch is changed over independently of the direction of rotation of the electric motor and always in the same position of the drive member.

An electric drive unit particularly adapted for actuating windshield wiper assemblies includes a motor having it's armature shaft carrying aportion having two oppositely pitched worm threads. Two worm gear wheels are disposed each on opposite sides of the threaded portion and in engagement therewith. The axes of rotation of the worm wheels are in parallel. Two spur wheels are each concentrically seated on a respective worm wheel. The spur wheels each engage a wheel having its axis of rotation located in a plane defined by the axes of rotation of the worm wheels. The toothed wheel is connected to a drive shaft.

Systems and methods for collecting data from one or more scoring candidates, storing such data in a database, and transforming such data using various techniques and software modules to generate a personal tracking and development score that determines an individual's proficiency for skills that are mapped to a job profile are depicted. Users may be ranked or compared against each other with similar units of measure. An attribute score may be used as a benefit for career development similar to the benefit a credit score may provide in assessing a user's financial records.

A windshield wiper for motor vehicles has a parking position of the wiper arm outside the wiping area, and includes a motor having a drive shaft, a crank guide member secured to the shaft, a resiliently biased crank member adjustable longitudinally of the guide member, switching means operable to initiate a parking movement and control means included in the switching means and engageable with a cam rotated with the crank member, upon activation of the switching means, to very the crank radius against the resilient bias. The control cam has, with respect to its direction of rotation, a steep ascent surface and an extended descent surface, which are engageable by the control member. Preferably the control cam is fixedly connected to the crank member and actuates an additional contact of the switching means only in the wiper parking position, to effect final switching off of the wiper motor.

This invention describes an electric motor on whose gear housing cap are secured plug contacts for a mating plug. Pin terminals which project perpendicularly from the gear housing cap are used as plug contacts. Various pin terminals are fixed on the cap, while other pin terminals are carried by a separate structural member which may be locked on the cap.
