  • Patent number: 7975796
    Abstract: An axle disconnect system for selectively connecting or disconnecting a wheel-side shaft and a differential-side shaft having a common axis of rotation in a drivetrain of a motor vehicle. In the axle disconnect an output gear is splined to the wheel-side shaft on an outside diameter of the wheel-side shaft, and a translatable collar is splined to the output gear on an outside diameter of the output gear. The collar is arranged to be translated along the common axis of rotation for splined connection with the differential-side shaft while retaining the splined connection with the output gear.

  • Patent number: 7922048
    Abstract: A spare tire carrier for a vehicle may structurally entail a base, a mounting flange extending from the base, a vertical support post extending from the base, a light support post attached to the vertical support post, a threaded stud that engages a front surface of the base to support a spare tire. A tether, which may be secured to the base with a fastener, may lie largely concealed within the base and have additional studs or bolts which may protrude through a front surface of the base and further support a spare tire. A plurality of strength ribs may join the mounting flange and the base, while the base, the first mounting flange, vertical support post extending from the base, and plurality of strength ribs may be a single cast magnesium part. The tether may be of another high strength material.

  • Patent number: 7914686
    Abstract: A process using an electrical signal for electrokinetic floatation of solids and semi-solids in paint sludge water includes collecting the paint sludge water into a tank. The process further includes generating the electrical signal from a bottom of the tank to separate the solids and semi-solids from the water in the paint sludge water to induce electrokinetic floatation of the solids and semi-solids to a top surface in the tank. After separating the solids and semi-solids from the water, the process includes removing the solids and semi-solids from the tank.

  • Patent number: 7898387
    Abstract: A vehicle function switch and a controller electrically are connected together. The controller has a passive mode of operation in which the controller is not responsive to activation of the vehicle function switch to transmit a vehicle function signal. The controller also has an active mode of operation in which the controller is responsive to activation of the vehicle function switch to transmit a vehicle function signal. A mode switch is associated with the controller and adapted to cause the controller to change from the passive mode of operation to the active mode of operation.

  • Patent number: 7894965
    Abstract: A transmission for a vehicle includes a first gear set and a second gear set. A first plurality of elements are operable in an applied state and a released state and a second plurality of elements are operable in an applied state and a released state. A controller toggles the first and second plurality of elements between the applied state and the released state to achieve a desired gear ratio. The controller times entry of at least one of the first and second plurality of elements into the released state with entry of at least another of the first and second plurality of elements into the applied state by controlling a hold pressure applied to the at least one element entering the released state. The controller determines the hold pressure by referencing current operating conditions of the transmission in a lookup table stored in a memory of the controller.

  • Patent number: 7891737
    Abstract: According to one embodiment of a seat assembly for a motor vehicle a seat back pivots about a hip axis, a seat bottom pivots about a knee axis, and at least one seat bottom leg is pivots about an ankle axis, so that the seat back folds down against the seat bottom and the seat bottom kneels on the floor to at least partially define a seating load floor. According to another embodiment, a seat bottom and a seat back are articulatable in a forward direction to fold the seat bottom and back down toward a floor of the vehicle to at least partially define a seating load floor.
