  • Patent number: 6976307
    Abstract: An accelerated vehicle development process includes establishing a common, standardized interface system whereby different types of vehicle bodies may be attached to a single chassis design. Chassis and bodies are designed, manufactured and validated independently of each other in accordance with the standardized interface system, thereby accelerating the development process. As new bodies are designed to mate with the previously manufactured and validated chassis, the newly designed bodies may be developed more quickly in response to market demand and attached to the previously validated chassis.

  • Patent number: 6976565
    Abstract: An axial positioner capable of yielding to absorb energy under compression or tension loads. The positioner includes an outer tube having first and second ends, a threaded actuator rod extending between the first and second ends and a drive to rotate the actuator rod. A threaded member threadably engaging the actuator rod moves axially between the ends of the outer tube as the actuator rod rotates. The member includes a radial flange extending toward the outer tube. A radially extending load ring spaced axially from the flange is connected to a plurality of axially extending force transmitting elements. A spring positioned between the flange and a load ring expands radially outward against the outer tube when compressed between the flange and the load ring. Loading of the spring against the tube absorbs energy of axial motion of the flange under excessive loads transmitted by the force transmitting elements to the load ring.

  • Patent number: 6959538
    Abstract: A sidestream located hyper-plasma reactor having an axially discrete pattern of alternating regions of active and passive electric field along the axial direction. The hyper-plasma reactor has great efficacy in terms of ultra low power consumption and copious production of NOx converting aldehydes in the absence of NO by applying plasma power only to an air and hydrocarbon mix sidestream gas flow. Only a small fraction (1% to 2%) of plasma power is required as compared to that for a conventional plasma reactor to treat the full exhaust gas stream. The hyper-plasma reactor produces ozone which reacts subsequently with hydrocarbons to produce aldehydes (“ozonolysis”). The sidestream location of the hyper-plasma reactor allows for the full exhaust stream to bypass it, without significantly affecting the overall NOx conversion performance in the catalytic converter.
