  • Patent number: 7290522
    Abstract: High compression ratio, homogeneous charge compression ignition engines. In one aspect the engine is dual mode utilizing spark ignition at high load levels including the addition of hydrogen or a hydrogen/carbon monoxide mixture. In another aspect, the engine operates on a high cetane fuel with the addition of hydrogen or a hydrogen/carbon monoxide mixture at low-to-mid-load levels.

  • Publication number: 20070144967
    Abstract: A method of separating a first fluid from a second fluid may include prewetting with the first fluid at least one channel defined by a separation device, the at least one channel thereby containing a column of the first fluid along its length. A combined flow of the first fluid and the second fluid may be presented to the separation device, so that the at least one channel is in fluid communication with the combined flow. Fluid pressure may be applied across the combined flow and the separation device, but the applied pressure should not exceed the capillary pressure in the at least one channel. Otherwise, the combined flow may be forced through the separation device. In this manner, the first fluid flows through the at least one channel, and the second fluid is excluded from the at least one channel, thereby separating at least a portion of the first fluid from the second fluid.

  • Patent number: 6786877
    Abstract: A self contained sensor apparatus generates a signal that corresponds to at least two of the three orientational aspects of yaw, pitch and roll of a human-scale body, relative to an external reference frame. A sensor generates first sensor signals that correspond to rotational accelerations or rates of the body about certain body axes. The sensor may be mounted to the body. Coupled to the sensor is a signal processor for generating orientation signals relative to the external reference frame that correspond to the angular rate or acceleration signals. The first sensor signals are impervious to interference from electromagnetic, acoustic, optical and mechanical sources. The sensors may be rate sensors. An integrator may integrate the rate signal over time. A drift compensator is coupled to the rate sensors and the integrator. The drift compensator may include a gravitational tilt sensor or a magnetic field sensor or both.

  • Patent number: 6176874
    Abstract: Solid free-form fabrication (SFF) methods are used to manufacture devices for allowing tissue regeneration and for seeding and implanting cells to form organ and structural components, which can additionally provide controlled release of bioactive agents, wherein the matrix is characterized by a network of lumens functionally equivalent to the naturally occurring vasculature of the tissue formed by the implanted cells, and which can be lined with endothelial cells and coupled to blood vessels at the time of implantation to form a vascular network throughout the matrix. The SFF methods can be adapted for use with a variety of polymeric, inorganic and composite materials to create structures with defined compositions, strengths, and densities, using computer aided design (CAD). Examples of SFF methods include stereo-lithography (SLA), selective laser sintering (SLS), ballistic particle manufacturing (BPM), fusion deposition modeling (FDM), and three dimensional printing (3DP).
