Abstract: An apparatus is provided for generating power, including modules connected in a closed loop. At least one module includes a duct. A motive fluid passes through the duct from the upstream side to the downstream side. An inlet fan is mounted in the duct at the upstream side for rotation about an axis. A motor or engine drives the inlet fan. A reaction turbine wheel is mounted in the duct downstream of the inlet fan on a rear shaft. The reaction turbine wheel has a plurality of pressure chambers disposed about the periphery of the reaction turbine wheel. The reaction turbine wheel is rotatable about the axis in a first direction, and the pressure chambers are curved from an upstream portion to a downstream portion in a second direction, opposite the first direction. An exhaust stator is mounted to the duct downstream of the reaction turbine wheel. An aft fan is mounted to the duct for rotation about the axis and is operably engaged to a rear axle.

Abstract: An acupressure patch for providing a controlled pressure to a selected point on the skin of a patient for a selected period of time is disclosed. The patch includes a rigid nub fixedly mounted to a flat rigid pressure plate. The pressure plate is positioned on an adhesive disc and held in place by an adhesive ring. The nub sits in an aperture such that it is not covered with any adhesive. A cushioning pad may also be provided between the pressure plate and the adhesive disc. The acupressure patch provides a low profile apparatus which can be secured to a patient's skin to provide adequate pressure to be effective but not to irritate the skin.
