  • Patent number: 7501621
    Abstract: A data acquisition system and method are described that may be used with various spectrometers. The data acquisition system may include an ion detector and a processing circuit. The processing circuit may include an initial processing module and a spectra processing module. According to one embodiment, the spectra processing module generates stick spectra and supplies the stick spectra to an external processor. The stick spectra comprise a peak intensity, resolution, and a location in the spectra for each detected peak. The initial processing module may contiguously sample the ion detection signals at a rate matched to the capabilities of the ion detector (up to at least 1.5 GHz) over a full spectral range. The spectra processing module may receive the processed signals and generate spectra from the processed signals at a rate matched to the time response of the separation techniques (up to 200 spectra/second).

  • Patent number: 7500706
    Abstract: A spring assist raising assembly includes a pivot pin with a noncircular cross section which is mounted to either a pivoted panel, such as a tailgate, or a stationary member, such as a vehicle body adjacent the tailgate. A spring-loaded rotatable socket is rotatably mounted to the other of the panel or member section and is keyed to receive the pivot pin and rotate with the rotation of the tailgate by such interconnection. The socket is coupled to a spiral torsion spring, in one embodiment of the invention, such that, as the panel or tailgate is lowered, the spiral torsion spring is loaded to provide a restorative force for assisting in the raising of the panel or tailgate.

  • Patent number: 7502446
    Abstract: A soft x-ray generator includes a unique pulse trigger assembly which reliably and reproducibly provides a plasma to initiate the discharge between a cathode and an anode, and having a cone-shaped geometry. The soft x-ray generator of the present invention also includes a rotating anode which is generally disk-shaped with an outer circumferential edge which can be rotated with respect to the cathode to expose different sections of the anode to the plasma discharge, thereby reducing anode wear and providing longer term operation. Anode erosion is also reduced by the liquid cooling of the anode during use. The generator utilizes a relatively low capacitance for the cathode-to-anode discharge and a relatively high voltage and pulse repetition rate (frequency) to achieve continuous reproducible results.

  • Patent number: 7497450
    Abstract: A method for making a vehicle suspension assembly includes forming a beam having a forward end defining a pivot, and a rearward end having an axle-receiving opening therethrough defined by a surface. At least a portion of the surface is generally cylindrical, and the surface defines a first diameter when the beam is at a first temperature. The method further includes providing an axle defining an axis and having a generally cylindrical outer surface portion defining a second diameter when the axle is at the first temperature, and wherein the second diameter is larger than the first diameter. The method further includes raising the temperature of the beam to expand the axle-receiving opening. The axle is then inserted into the axle-receiving opening while the opening is expanded due to the elevated temperature. The temperature of the beam is then lowered to provide a tight interference fit between the beam and the axle member.

  • Patent number: 7497044
    Abstract: A magazine for a firearm includes an elongated containing body and a closure member adapted to hold cartridges. The closure member longitudinally slides on the containing body and is extendable to open a side of the containing body for cartridge loading. The closure member has opposing sidewalls forming an integral handle surface that can be grasped for moving it. A follower and spring bias cartridges toward one end of the magazine. A latching mechanism is provided for holding the follower in a disengaged position when the closure member is extended, and is configured to release when the closure member is closed. Preferably, the containing body and closure member are constructed to include integrally formed features that cooperate with an automatic latching mechanism, thus minimizing parts.

  • Patent number: 7494165
    Abstract: A bumper system includes a tubular beam (21) and a thermoformed energy absorber with crush boxes (23) formed into a base flange, such as by vacuum or thermal forming processes. The crush boxes have planar energy-absorbing sidewalls a depth of about 10 mm to 35 mm, wall thickness of about 1 mm to 3 mm, and are formed from polyethylene or other thermoform materials having a memory. The base flange can include thermoformed features engaging recesses in the beam, and is combinable with injection-molded or foam energy absorbers for design flexibility. In one form, the energy absorber includes a thermoformed first sheet forming crush boxes and a second sheet bonded to the first sheet to define apertured air pockets. Related methods of manufacture and impacting are also disclosed.

  • Patent number: 7494192
    Abstract: A vehicle wheel and overlay assembly having an overlay that extends radially outward to cover substantially the entire outboard surface of the wheel, without wrapping around the periphery of the wheel. The assembly includes a wheel having a flangeless or minimum functional flange height rim flange or alternatively a truncated rim flange that terminates in a flange lip having a radially outermost edge. An overlay is attached to and closely contours the wheel outboard surface and radially terminates in a peripheral flange that has a peripheral lip with a radially outermost edge that is aligned with the outermost edge of the wheel flange lip within a predetermined circumferential margin so that the peripheral flange covers at least a portion of the wheel flange lip. This configuration gives the visible impression that this is a one-piece wheel, where the outboard surface of the overlay appears to be the outboard surface of the wheel, and not a separate component.

  • Patent number: 7490392
    Abstract: A cushion subassembly includes a support, a cushion of non-woven polymeric (PET) or PETE fibers with a formed edge that wraps over an edge of the support, and an upholstery sock pulled onto and covering the support and the cushion. The formed edge has sufficient structure to retain the cushion in place on the support as the upholstery sock is pulled onto the support. A back support shell supports the cushion assembly, and has first fasteners that engage in a first direction and second fasteners that prevent disengagement. The cushion assembly is stressed during assembly, especially at corners, but is thermally stress-relieved after assembly to relax the polymeric fibers and the upholstery sock to a state of minimized balanced tension. The back support shell includes a shallow depression on its face. The cushion fills the depression sufficient to eliminate loose fabric but provides a same force deflection curve across its shape.
