Publication number: 20080184830Abstract: A steering apparatus includes a housing defining a chamber and an aperture extending into the chamber. A rack is disposed within the chamber and moveable along a longitudinal axis. A pinion extends into the chamber for meshing engagement with the rack. A bearing supports the rack within the chamber relative to the housing. The bearing includes a wall having a continuously varying radial thickness. An adjustment mechanism includes a shaft partially disposed within the aperture in threaded engagement with the aperture and engaging the bearing for rotating the bearing about the longitudinal axis, thereby repositioning the rack relative to the pinion. A plug is disposed within the aperture. A spring is disposed within the aperture between the plug and the shaft to bias against the shaft, thereby urging rotational threaded movement of the shaft to produce linear movement of the shaft into engagement with the bearing.Type: ApplicationFiled: April 14, 2008Publication date: August 7, 2008Applicant: DELPHI TECHNOLOGIES, INC.Inventor: George E.

Patent number: 7408123Abstract: A seat occupant sensing apparatus includes a notched foam bottom seat cushion and a pressure-responsive sensor disposed between the bottom cushion and a frame of the seat. The notch is a narrow channel on the underside of the foam cushion that extends upward into the foam to limit and direct dispersion of occupant loading through the cushion. A rectangular notch smaller in dimension than a child seat frame is formed in a central region of the foam cushion, and a fluid-filled bladder or other force-responsive sensor mat is disposed substantially within the perimeter of the notch. The sensor will detect a normally seated occupant due to the relatively uniform seat load, but will not detect a cinched-down child seat because the notch limits dispersion of child seat loading in the direction of the sensor.Type: GrantFiled: November 16, 2006Date of Patent: August 5, 2008Assignee: Delphi Technologies, Inc.Inventors: Kevin J. Hawes, Duane D. Fortune, Morgan D. Murphy

Patent number: 7404540Abstract: A primary pole piece (PPP) for an electrical solenoid linear actuator includes an inner skirt portion extending axially from a radial flange portion and having a substantially uniform cylindrical thickness and a non-uniform axial length. The skirt is formed into a plurality of “saw teeth” or other axially-extending and circumferentially tapered elements separated by axially extending notches or similar axial inlets along the terminal skirt edge. Whereas in the prior art the magnetic flux is intensified radially by conical formation of the skirt, in the present invention the magnetic flux is intensified azimuthally by being collected in and directed to terminal flats of the saw teeth. The entire PPP may be net-formed by conventional powdered metal press/sintering, requiring no post-forming machining. Preferably, the molded PPP is conventionally sintered to increase density and is impregnated for plating.Type: GrantFiled: February 2, 2006Date of Patent: July 29, 2008Assignee: Delphi Technologies, Inc.Inventors: Joseph D.

The second and third transistor pair are similarly assigned. The first method also includes always starting a voltage waveform generated by the first transistor pair substantially at the beginning of the PWM period when a commutation state requires a voltage waveform from the first transistor pair but delaying starting a voltage waveform generated by the second transistor pair by substantially ? of the PWM period and delaying starting a voltage waveform generated by the third transistor pair by substantially ? of the PWM period.Type: GrantFiled: March 23, 2006Date of Patent: July 22, 2008Assignee: Delphi Technologies, IncInventors: Robert J.

Patent number: 7403848Abstract: Impending rollover events are detected based on vehicle roll rate, roll angle and lateral acceleration, and an assessment of the relative polarities of vehicle roll rate and lateral acceleration. When the vehicle roll rate and lateral acceleration are opposite in polarity, the roll rate vs. roll angle thresholds used to distinguish between rollover events and non-rollover events are more sensitive than for conditions for which the vehicle roll rate and lateral acceleration are of the same polarity. Additionally, the roll rate vs. roll angle thresholds are adaptively modified based on roll angle and lateral acceleration to provide increased detection sensitivity under conditions that typically precede a rollover event, and reduced detection sensitivity under conditions for which a rollover event is unlikely.Type: GrantFiled: August 16, 2004Date of Patent: July 22, 2008Assignee: Delphi Technologies, Inc.Inventors: Peter J. Schubert, Chad M. Aeschliman

Patent number: 7401596Abstract: The invention relates to a method of estimating the temperature of a piezoelectric actuator body for controlling the operation of a fuel injector mounted within an engine housing and supplied with fuel from a high pressure fuel pump. The piezoelectric actuator body is housed within a volume of fuel. The method comprises determining a temperature (T—INJ IN, T—PUMP IN) of fuel upstream of the fuel volume, determining a temperature (T—CYL) of the engine housing, and estimating a temperature (T—STACK STEADY STATE; T—STACK DYNAMIC) of the piezoelectric actuator body based on the upstream temperature (T—INJ IN, T—PUMP IN) and the temperature (T—CYL) of the engine housing. By considering the heat transfer between the piezoelectric actuator body, the injector and fuel within the volume, and the heat transfer due to fuel flow through the volume for an injection, the temperature of the piezoelectric actuator body can be estimated by modelling or mapping.Type: GrantFiled: January 19, 2007Date of Patent: July 22, 2008Assignee: Delphi Technologies, Inc.Inventors: Martin A. P. Sykes, Joseph R Walsh, Daniel J. Hopley
