摘要： This invention includes a system and method for maintaining an impeller (30) in a centrally located position in a pump cavity defined by an impeller housing (34) in order to reduce noise and vibration between the impeller (30) and the impeller housing (34). The system and method include situating an end or tip (42) of the impeller (30) in a bearing (44) which is integrally molded onto the impeller housing (34) at an inlet end (35) thereof. Another embodiment illustrates the use of a locator integrally molded at the inlet end of the impeller housing and which cooperates with a locating aperture in an impeller end of the impeller to cause the impeller end to be maintained in a substantially centrally located position in the pump cavity defined by the impeller housing.

摘要： A system and method for maintaining a washer fluid above a predetermined temperature at a point of delivery where the fluid is directed onto a windshield of a vehicle. The system and method include a washer nozzle (26) that has an internal resistance such that, when a current is passed through the nozzle, a temperature of nozzle is maintained at a predetermined temperature which is above the freezing temperature of the fluid. In one embodiment, the nozzle body (28) and its electrical terminals (36, 38) are an one-piece molded construction, with another embodiment having a plurality of metallic conductors (40, 42) insert-molded into the nozzle. The nozzle (26) has a nozzle body (28) which is molded of an electrically conductive, internally-resistive, thermo-plastic which can be energized with less than about twenty or even ten amperes so that the nozzle body temperature is maintained.

摘要： A windshield wiper system and method comprising a controller which cooperates with a single sensor (30) positioned in fixed relationship to a target (32) situated on an armature (22) of a drive motor (20) which is driven in response to the controller. The wiper motor (20) is a reversing wiper motor and changes direction in response to a change of polarity of drive signal generated by controller. An interrupt (34) is situated on a drive train (24) driven by the armature (22) of the wiper motor (20) and moves in correlation to the movement of a wiper blade. The sensor (30) generates a pulse train associated with the movement of the wiper blade, and this pulse train gets interrupted by the interrupt (34) when the wiper blade reaches a reversing position, such as an inwipe or an outwipe position. The interruption thereby gives controller an indication of when to reverse the polarity of the drive signal used to drive the wiper motor (20). The controller also uses the polarity of the drive signal to determine direction and, when used in combination with the sensor signal pulse train, to determine the velocity and position of the wiper blade. This, in turn, enables controller to control the velocity and direction of the wiper blades.
摘要翻译：一种挡风玻璃刮水器系统和方法，包括控制器，所述控制器与位于与所述驱动电动机（20）的电枢（22）上的目标（32）固定关系定位的单个传感器（30）相配合，所述衔铁（22）响应于所述控制器。刮水器马达（20）是反向刮水器马达，响应于由控制器产生的驱动信号的极性的变化而改变方向。中断（34）位于由刮水器马达（20）的电枢（22）驱动的传动系（24）上，并与刮水片的运动相关地移动。传感器（30）产生与刮水片的运动相关联的脉冲串，并且当刮水片到达反转位置（例如内向或外向位置）时，该脉冲串被中断（34）中断。因此，中断使得控制器指示何时反转用于驱动刮水器马达（20）的驱动信号的极性。控制器还使用驱动信号的极性来确定方向，并且当与传感器信号脉冲串组合使用时，确定刮水片的速度和位置。这又使得控制器能够控制刮水片的速度和方向。
