  • Publication number: 20120204374
    Abstract: Apparatus for providing a heated cleaning fluid to a vehicle surface having an inlet port for receiving an amount of fluid; a housing bounding a reservoir in fluid communication with the inlet port; and an outlet port in fluid communication with the reservoir for dispensing an amount of heated fluid. A heater element heats fluid that passes from the inlet to the outlet port through the reservoir. A heat exchanger in thermal contact with the heater element for conveying heat to the fluid within the reservoir has a strut that divides fluid entering the housing through the inlet port into two flow paths and elongated fins that extend outwardly from the strut at transverse angles that bound fluid flow channels for fluid moving through said reservoir. A control circuit energizes the heater element with a voltage to heat the heating element.

  • Publication number: 20110041409
    Abstract: A vehicle assembly includes an electrically non-conductive fascia panel and an electrical conductor mounted to the fascia panel. The conductor capacitively couples to an electrically conductive object proximal to the fascia panel while the conductor is driven with an electrical charge such that capacitance of the conductor changes due to the conductor capacitively coupling with the object. The assembly may further include a controller operable for driving the conductor with the electrical charge and for measuring the capacitance of the conductor to determine whether an electrically conductive object is proximal to the fascia panel. The controller controls a vehicle function such as movement of a movable panel like a lift gate associated with the fascia panel depending on whether an electrically conductive object is proximal to the fascia panel.

  • Publication number: 20110043325
    Abstract: A keyless entry assembly includes a vehicle opening movable between locked and unlocked positions, an electrical conductor (i.e., a capacitance sensor) mounted to the vehicle opening, and a controller. The conductor capacitively couples to an electrically conductive object proximal to (or touching) the conductor while the conductor is driven with an electrical charge such that capacitance of the conductor changes due to the conductor capacitively coupling with the object. The conductor is in the shape of an emblem identifying a vehicle associated with the vehicle opening. The controller is operable for driving the conductor with the electrical charge and measuring the capacitance of the conductor to determine whether an electrically conductive object is proximal to the conductor. The controller is further operable for controlling the vehicle opening to move the vehicle opening between the positions upon determining that the object is proximal to (or touching) the conductor.

  • Publication number: 20110001722
    Abstract: A system for enabling an operator to control a vehicle accessory includes a control interface and a processor. The control interface has a display surface and a touch area defined by an electrically conductive layer adjacent the display surface. The conductive layer capacitively couples to an electrically conductive object upon the object touching or being in proximity with the touch area while the conductive layer is driven with an electrical charge. The processor drives the conductive layer with the electrical charge, detects the capacitive coupling of the conductive layer to the object upon the object touching or being in proximity with the touch area while the conductive layer is driven, generates a signal indicative of the object touching or being in proximity with the touch area upon detecting the capacitive coupling of the conductive layer to the object, and provides the signal to the accessory for controlling the accessory accordingly.

  • Publication number: 20100097040
    Abstract: A hydraulic system includes a variable displacement hydraulic pump connectable to a power source, a hydraulic motor, a fluid circuit, a pump displacement control, and a controller. The pump has an inlet for receiving fluid, an outlet for discharging pressurized fluid, and a pump displacement input. The motor has an inlet for receiving pressurized fluid and an outlet for discharging spent fluid. The fluid circuit includes a supply conduit for conducting fluid discharged by the pump to the motor and a return conduit for returning fluid discharged by the motor to the pump. The pump displacement control cooperates with the pump displacement input to vary pump displacement. The controller communicates with the pump displacement control to control the pump output such that the motor is driven at a constant speed to thereby drive a generator connected to the motor at a constant speed despite speed fluctuations of the power source.

  • Publication number: 20090198420
    Abstract: A system includes a controller and a sensor. The controller is configured to transmit a panel control signal to a motor for the motor to move a movable panel of a vehicle along a path between opened and closed positions. The sensor is configured to detect an object in the path of the panel without monitoring the motor. The sensor is further configured to generate an object signal indicative of an object detected in the path of the panel. Upon receipt of the object signal, the controller is further configured to transmit a panel control signal to the motor to move the panel along the path in an opening direction towards the opened position in order to prevent the panel from entrapping the object. The controller is further configured to communicate with at least one vehicle module over an in-vehicle local area network (LAN).

  • Publication number: 20090158857
    Abstract: An anti-entrapment system for preventing an object from being entrapped by a translating device includes a sensor positionable adjacent to or on the translating device. The sensor has a non-conductive compressible jacket with a cavity, and first and second conductors positioned within the cavity opposite from one another. In response to an object pressing against the jacket, the jacket compresses from a non-compressed state in which the conductors are not in electrical contact to a compressed state in which the conductors are in electrical contact. The sensor has a compressible support either inside or outside of the cavity. In response to the object pressing against the jacket while the jacket is compressed, the support compresses to allow the jacket to compress further in order reduce pinching of the object by the translating device when the object is between the jacket and the translating device.

  • Patent number: 7530269
    Abstract: A fuel level sensor for sensing and monitoring the level of remaining fluid in a container such as a fuel tank for a motorized vehicle is disclosed. The fuel level sensor incorporates an improved float and pivot arm member attached to a hub that rotates about a pivot base. The conventional resistor card technology, commonly found in automotive applications for translating the position of the float into an electrical signal, is replaced by a more reliable non-contact magnetic flux sensing circuit. The fuel level sensor incorporates a magnetic sensor and magnetic circuit in a commonly known and practiced rotational position sensor configuration for determining the angular position of a hub relative to its pivot base, where the hub is attached to a conventional float-arm member and the base remains stationary relative to the fuel container. The preferred embodiment includes a magnetic flux sensor positioned between two movable magnets.
