  • Patent number: 10132739
    Abstract: A particle manipulation system uses a MEMS-based, microfabricated particle manipulation device which has an inlet channel, output channels, and a movable member formed on a substrate. The movable member moves parallel to the fabrication plane, as does fluid flowing in the inlet channel. The movable member separates a target particle from the rest of the particles, diverting it into an output channel. However, at least one output channel is not parallel to the fabrication plane. The device may be used to separate a target particle from non-target material in a sample stream. In the event that the microfabricated particle manipulation device malfunctions as a result of a particle of debris becoming lodged in the microfabricated particle manipulation device, the system may invoke a recovery algorithm, that includes vibrating the microfabricated particle manipulation device using a pulse train at a frequency near its mechanical resonance.

  • Patent number: 8668168
    Abstract: The present invention is a space vehicle valve system which controls the internal pressure of a space vehicle and the flow rate of purged gases at a given internal pressure and aperture site. A plurality of quasi-unique variable dimension peaked valve structures cover the purge apertures on a space vehicle. Interchangeable sheet guards configured to cover valve apertures on the peaked valve structure contain a pressure-activated surface on the inner surface. Sheet guards move outwardly from the peaked valve structure when in structural contact with a purge gas stream flowing through the apertures on the space vehicle. Changing the properties of the sheet guards changes the response of the sheet guards at a given internal pressure, providing control of the flow rate at a given aperture site.

  • Patent number: 8622089
    Abstract: The present invention provides a check valve 10 through which a fluid can satisfactorily open and pass when the fluid flows forward, and a bag 1a including the check valve and having a function of satisfactorily discharging a fluid. This check valve includes a one-side airtight base sheet 31, an inlet 11, a valve sheet 61, an auxiliary sheet 51, and the other-side airtight base sheet 21. The portion between the other-side airtight base sheet 21 and the valve sheet 61 serves as a valve flow channel 13, and a fluid flowing forward passes through the valve flow channel 13 from the inlet 11 and flows out from the outlet 12. The valve sheet 61 is fixed at its upstream end by the fixation portion 14, is freely movable at its downstream end. On the fixation portion 14 and the one-side airtight base sheet 31 of the inlet 11, the introduction recesses 15 are formed.

  • Patent number: 8602062
    Abstract: Compact reeds maximize flexural length by efficiently utilizing available space surrounding the port. Maximum length arms are disposed at the perimeter of the housing inlet port. Stresses at the ends of the arms are mitigated by utilizing compound radius transitions. The transitions are constructed by two or more arcs of different radii, which produce lower stresses at such junctures than if single radius transitions were used. The arms are disposed close to the reed sealing surface edge to orient the flow streamlines to be aligned with the arm width, thereby minimizing frontal drag area. The reduced frontal area reduces drag forces and related stresses on the arms, and reduces the overall flow related pressure drop across the reed. Replacing a single hole port, a port comprised of multiple passages of varying size control the velocity exiting the passages. The velocity gradient across the port provides further capability to orient the said streamlines to reduce said drag.

  • Patent number: 8590573
    Abstract: A microfabricated fluidic unidirectional valve includes a microfabricated elastomer material having a flow through channel. The microfabricated fluidic unidirectional valve also includes an elastomer flap attached to the elastomer material in the flow through channel. The elastomer flap forms a seal in the flow through channel to prevent fluid from flowing in a first direction through the flow through channel and to allow fluid flow in a second direction through the flow through channel.

  • Patent number: 8568116
    Abstract: A compressor wherein a valve plate formed with a suction hole and a discharge hole is interposed between a cylinder head and a cylinder block and a discharge valve formed as a reed valve is provided relative to the discharge hole on the valve plate. The discharge hole is formed in a U-shape having a bottom part located at the tip side of the reed valve, and the reed valve is formed as a U-shape extending in correspondence to the U-shape of the discharge hole. The cross-sectional area of flow of discharge gas can be significantly increased to drastically reduce flow path resistance, and excessive compression may be suppressed to greatly improve the efficiency of the compressor.
