  • Patent number: 7306755
    Abstract: A strap with rotatably mounted clip fabricated in a single molding operation. The strap includes a strap retention member and a plurality of teeth. The rotatable clip includes a clip member, a pedestal and a head. The pedestal is retained in a pedestal opening formed through the strap. In fabrication, a top mold insert is slid into a top of first and second mold halves and a bottom mold insert is slid into a bottom of the first and second mold halves. Plastic is then injected into the first and second mold halves to independently and separately form the strap and the clip in a single molding process, wherein the inserts provide a space between the pedestal opening and the pedestal to allow the clip to rotate relative to the strap.

  • Patent number: 7308347
    Abstract: A frame-based occupant weight estimation apparatus for a vehicle seat includes compliant load transfer mechanisms interposed between the seat frame and floor brackets bolted to the vehicle floor. The compliant load transfer mechanisms translate the seat loads to a central location for measurement by a set of force sensors. The load transfer mechanisms preload the force sensor to enable off-loading detection, and an overload device securely anchors the seat to the floor bracket without interfering with normal load measurement.

  • Patent number: 7306871
    Abstract: A system for co-generation of electricity combining a hydrocarbon catalytic reformer, an SOFC assembly and a generator driven by a gas turbine. The fuel cell assembly recycles a high percentage of anode exhaust gas into the reformer. Oxygen for reforming is derived from water in an endothermic process. The stack exit temperature is normally above 800° C. DC power from the fuel cell assembly and AC power from the gas turbine generator are directed to a power conditioner. Anode exhaust gas including carbon monoxide and hydrogen is divided into a plurality of portions by which heat may be added to the reforming, gas turbine, and cathode air heating processes. Water may be recovered from the exhaust. A power system in accordance with the invention is capable of operating at a higher total efficiency than either the fuel cell component or the gas turbine component alone.

  • Patent number: 7305949
    Abstract: A target wheel for a camshaft phaser stamped and drawn from sheet metal stock. The hub region of the target wheel may be drawn such that it extends through the phaser cover plate and seals directly against the face of the rotor, allowing a shorter cam bolt and resulting in reduction in mass and cost of the phaser. Alternatively, a separate hub is formed and then attached to a simplified stamped and drawn target wheel, or a target wheel hub is formed integrally with the rotor and extends through the cover plate to mate with a simplified stamped and drawn target wheel. Preferably, the hub is formed having a neck extending through a central opening in the target wheel, which neck is peened over during assembly to secure the wheel to the hub.

  • Patent number: 7303936
    Abstract: A technique for forming anti-stiction bumps on a bottom surface of a micro-electro mechanical (MEM) structure includes a number of process steps. The MEM structure is fabricated from an assembly that includes a support substrate bonded to a single-crystal semiconductor layer, via an insulator layer. A plurality of holes are formed through the single-crystal semiconductor layer to the insulator layer on an interior portion of a defined movable structure. A portion of the insulator layer underneath the holes is removed. The holes are then filled with a conformal film that extends below a lower surface of the defined movable structure to provide a plurality of anti-stiction bumps. A trench is then formed through the single-crystal semiconductor layer to the insulator layer to form the defined movable structure. Finally, a remainder of the insulator layer underneath the defined movable structure is removed to free the defined movable structure.
