Publication number: 20090229630Abstract: A selectively controllable heated wash system for a vehicle surface includes a wiper system control module operatively disposed in the vehicle and may be adapted to receive at least one sensed input. A fluid heating module is controlled by the wiper system control module, the heating module adapted to heat fluid therein to a predetermined target temperature, or to a preferred temperature determined as a result of recognition and analysis of the sensed input(s). Fluid is dispensed onto the surface from the heating module manually, according to predetermined parameters, or according to predetermined parameters determined at least in part as a result of recognition and analysis of the sensed input(s).Type: ApplicationFiled: October 17, 2006Publication date: September 17, 2009Applicant: Valeo Electrical Systems Inc.Inventors: Eugene B. Porter, Daryl G. Harris

Patent number: 7190893Abstract: A fluid heater apparatus and method of making same includes a low porosity material, thermally conductive mass. A heat source is disposed in the thermally conductive mass for imparting heat to the mass. Fluid in a flow path through the mass absorbs heat from the mass. The thermally conductive mass is molded, cast or extruded from a material which, with the selected forming process, provides a low porosity mass. The mass may be formed of ceramic, aluminum and poltruded carbon. The mass can be cast from a material which is introduced into the casting mold in a semi-solid temperature state.Type: GrantFiled: June 27, 2003Date of Patent: March 13, 2007Assignee: Valeo Electrical Systems, Inc.Inventors: Karl-Heinz Kuebler, Daryl G. Harris, Lee A. Bissonnette

Patent number: 6912357Abstract: A fluid heater apparatus supplies heat to wash fluid via a continuous, labyrinthian flow path in a thermally conductive body. A heat source is disposed in the thermally conductive body for imparting heat to the body. Fluid flowing through the thermally conductive body substantially envelopes the heat source to absorb heat from the body.Type: GrantFiled: January 29, 2002Date of Patent: June 28, 2005Assignee: Valeo Electrical Systems, Inc.Inventors: Lee A. Bissonnette, Daryl G. Harris, Mark A. Pattison

Patent number: 6850699Abstract: A method and apparatus for controlling fluid temperature in a fluid heater apparatus which supplies heat to fluid from a controllable heater element(s) which includes establishing a discharge temperature range between a first high temperature and a second low temperature. The temperature of the fluid is measured and, in response to the measured temperature, activation of the heater elements is controlled to maintain the temperature of the fluid within the temperature range. The heater elements can be independently controllable for temperature control.Type: GrantFiled: February 28, 2003Date of Patent: February 1, 2005Assignee: Valeo Electrical Systems, Inc.Inventors: Karl-Heinz Kuebler, Daryl G. Harris, Mark M. Benner, Lee A. Bissonnette

Patent number: 6839509Abstract: A fluid heater apparatus has fluid discharge temperature control to prevent temperature overshoot. A plurality of heater elements are employed and at least certain of the heater elements are independently controllable. At least one of the heater elements is employed as a “finishing” heater element, with the other heating elements deactivated to enable the “finishing” heater element to more slowly elevate the temperature of the fluid in the body from a first temperature reached by activation all or most of the heater elements to the predetermined discharge temperature. One of more of the heater elements may have a different power output than the other heater elements.Type: GrantFiled: February 28, 2003Date of Patent: January 4, 2005Assignee: Valeo Electrical Systems, Inc.Inventors: Karl-Heinz Kuebler, Daryl G.

Publication number: 20040170412Abstract: A heat source is disposed in the thermally conductive mass housing for imparting heat to the mass. Fluid in a flow path through the mass absorbs heat from the mass. A fluid expansion member is mounted over open ends of the fluid flow path. The fluid expansion member, in one aspect, is formed of a compressible material to compress under the forces of fluid phase change to a solid state and expands back to a nominal shape when the fluid undergoes a reverse phase change to a liquid state. In another aspect, the fluid expansion member is a solid seal member overlaying the open ends of the fluid flow channels. The seal resists expansion under normal fluid operating pressures, but expands into an open interior chamber in a closure fixed to the mass to accommodate a phase change expansion of the fluid.Type: ApplicationFiled: February 28, 2003Publication date: September 2, 2004Inventors: Karl-Heinz Kuebler, Daryl G. Harris

Patent number: 6393653Abstract: A windshield wiper apparatus for a vehicle includes an energy absorption member coupled between the moving drive arm and stationary structure which provides an opposing force to the movement of the wiper arm to absorb a portion of the inertial energy of the wiper arm as the wiper arm approaches one of at least an outwipe end limit and an inwipe end limit of a wipe pattern to reduce the impact forces on the wiper apparatus at the point of reversal of the wiper arm. The energy absorption member is in the form of a spring or compressive member arranged to store energy during movement of the wiper arm toward one or both of the end limits and to release the stored energy back to the wiper apparatus as the wiper arm reverses direction at each end limit. The energy absorption member is actively coupled to the drive arm only during a predetermined angular portion of the angular rotation of the drive arm which coincides with the region of increased mechanical advantage in the drive linkage.Type: GrantFiled: November 19, 1999Date of Patent: May 28, 2002Assignee: Valeo Electrical Systems, Inc.Inventors: Daryl G.
