摘要： Embodiments of the present disclosure include a motor controller with a processor and a machine readable medium. The medium includes instructions that, when loaded and executed by the processor, cause the processor to receive an estimated or sensed speed of a motor, extract a mechanical frequency component from the estimated or sensed speed, transform the mechanical frequency into direct quadrature (DQ) domain at the mechanical frequency, control the mechanical frequency to zero, and generate a dampening signal for torque based upon the controlled mechanical frequency.

摘要： A system is disclosed for washing a selected component and removing the selected component from a wash material. The selected component may include red blood cells that are washed to remove a rejuvenating solution. The red blood cells may then be removed with various systems, such as a standing acoustic wave system from the wash solution. Pumps and flow restrictors that provide steady flow from pumps that generate pulsed flow are also disclosed.

摘要： A scroll compressor includes a pressing mechanism, a pushback mechanism and an adjustment mechanism. The pressing mechanism applies a pressing force toward a fixed scroll to the back side of an end plate portion of an orbiting scroll. The pushback mechanism applies a pushback force separating the orbiting scroll from a fixed scroll to the front of the orbiting scroll. The adjusting mechanism has a low-pressure portion filled with a fluid of a lower pressure than the discharge pressure of the compression mechanism, and a communicating groove formed in a sliding surface of an outer peripheral portion of the fixed scroll so as to communicate with the low-pressure portion in a first rotational angle range in order to reduce an upsetting moment of the orbiting scroll, and to be blocked from the low-pressure portion in a second rotational angle range other than the first rotational angle range.

摘要： A pump assembly includes a rotating component and a stationary component coupled to the rotating component such that the stationary component substantially circumscribes at least a portion of the rotating component. A high pressure outlet extends at least partially through the rotating and stationary components. An inlet is positioned a predefined distance from the high pressure outlet. The inlet extends at least partially through the rotating and stationary components. A solid fuel flow is channeled from the inlet to the outlet as the rotating component rotates. A flow control member is coupled to the rotating and stationary components in a first predefined position. The flow control member is selectively moveable from the first predefined position to a second predefined position to form a seal within the pump assembly such that the solid fuel flow and a fluid flow are substantially restricted from being channeled back into the inlet.

摘要： A radial pump has a housing with a cylinder ring pivotally mounted therein. The cylinder ring has a circular aperture within which a cam surface is formed. A cylinder block rotates within the cylinder ring aperture and has a plurality of radially extending cylinders each having port which selectively communicates with a fluid inlet and a fluid outlet as the cylinder block rotates. A plurality of pistons is slideably received within the cylinders and engages the cam surface. The movement of the pistons within the cylinders is directly related to the magnitude of fluid flow delivered by the pump and moving the cylinder ring thereby controls the fluid flow.
