Patent number: 6859144Abstract: A system responds to detection of a vehicle situation by comparing a sensed eye gaze direction of the vehicle operator with data stored in memory. The stored data defines a first predetermined vehicle operator eye gaze direction indicating a high probability of operator desire that an alert signal be given and a second predetermined vehicle operator eye gaze direction indicating a low probability of operator desire that an alert signal be given. On the basis of the comparison, a first or second alert action is selected and an alert apparatus controlled accordingly. For example, the alternative alert actions may include (1) generating an alert signal versus not generating the alert signal, (2) generating an alert signal in a first manner versus generating an alert signal in a second manner, or (3) selecting a first value versus selecting a second value for a parameter in a mathematical control algorithm to determine when or whether to generate an alert signal.Type: GrantFiled: February 5, 2003Date of Patent: February 22, 2005Assignee: Delphi Technologies, Inc.Inventors: Timothy J.

Patent number: 6857659Abstract: A tethering restraint system is provided which restrains an inflatable air bag cushion during an extended period of inflation rather than limiting such restraint to the final stages of inflation. Maintaining tethering restraint during the inflation cycle increases the time over which energy is transferred between the air bag cushion and an occupant to be protected thereby reducing the instantaneous force transferred between the occupant and the air bag cushion as contact takes place.Type: GrantFiled: December 20, 2002Date of Patent: February 22, 2005Assignee: Delphi Technologies, Inc.Inventor: James Lloyd Webber

Patent number: 6854765Abstract: A steering shaft assembly has a tubular main body and a shaft, with a spring and a sleeve disposed at least partially therebetween. The shaft is disposed at least partially in the tubular main body and the sleeve is disposed at least partially between the spring and the main body. The sleeve acts to urge the spring into frictional contact with the shaft to impart an axial resistance force supporting the shaft against axial displacement in response to application of an axial force on the shaft less than the axial resistance force. The sleeve enables axial displacement of the shaft in response to application of an axial collapsing force exceeding the axial resistance force. In another construction of a steering shaft assembly, a shaft is disposed at least partially in the tubular main body and the spring is disposed at least partially in the tubular main body between the tubular main body and the shaft. The spring acts to impart a radial load between the shaft and the tubular main body.Type: GrantFiled: September 23, 2002Date of Patent: February 15, 2005Assignee: Delphi Technologies, Inc.Inventors: Marc William Heinzman, Michael Patrick Anspaugh

Patent number: 6856495Abstract: An improved series-pass over-voltage protection circuit includes a P-channel enhancement mode MOSFET (PFET) continuously coupling a DC voltage supply such as a motor vehicle storage battery to one or more electrical loads. The source of the PFET is connected to the positive terminal of the DC voltage supply, and in normal operation, low quiescent current draw is achieved by coupling the gate of the PFET to the negative terminal of the power supply through a low-current current sink. A gate discharge amplifier including a high current capability transistor connected across the source-to-gate circuit of the PFET is activated by a controlled current sink when an over-voltage occurs at the drain of the PFET, and the inherent high impedance of the current sinks relative to the gate discharge amplifier provides high immunity of the PFET to input voltage transients. The result is a practical and highly effective over-voltage protection circuit for continuously powered electrical loads.Type: GrantFiled: May 31, 2002Date of Patent: February 15, 2005Assignee: Delphi Technologies, Inc.Inventor: Jeffrey A. Ely
