Abstract: An oxygen concentrator system that includes or can be expanded to include more than one compressor is provided. The system utilizes a controller that is adapted to selectively activate or deactivate one or more of the compressors to optimize system performance and efficiency. Multiple compressors can be selected to operate at the same time, thereby enabling the system to operate at a higher peak pressure, increase the recovery of the PSA cycle, and expand the product rate. The additional compressors can also be removed when not in use so as to reduce weight of the system. In some implementations, the system housing reserves a certain amount of space for accommodating additional compressors and related components, which can be added to the system as after market parts. In other implementations, the additional compressor can be located external to the system.

Abstract: In an embodiment, the invention is an improved interface to a conserver for therapeutic gas delivery. The improved circuit allows for fine control of the frequency response of a feedback element, which permits a high gain interface. The result is excellent compensation of transducer drift with little distortion of the frequencies of interest for breath detection, even for low breath pressure scenarios.

Abstract: A variable speed wind turbine employing a rotor connected to a multiplicity of synchronous generators with wound field or permanent magnet rotors. A passive rectifier and an inverter are used for power transfer back to the grid. A Turbine Control Unit (TCU) commands a required generator torque based on rotor speed and power output of the turbine inverters. Torque is controlled by regulating the DC current by control of the inverter. A main-shaft-damping filter is provided by measurement of the DC bus voltage. In high winds the turbine remains at a constant average output power through a constant torque command and a varying pitch command to a rotor pitch servo system. A set point is fixed at the inverter output such that output VAR load is minimized running the turbine at very nearly unity power factor. Dynamic VAR and power factor control is provided by a separate VAR apparatus.
