Abstract: A DC power plant generating DC power from a variety of engines including a Stirling cycle engine. The DC power plant includes a relatively small start-up power source that is discontinued after the engine is running. A method for producing DC power for a load including starting up an engine using power supplied by a relatively small power supply supplemented by a capacitor bank, providing output from the engine to a generator, producing alternating current (AC) power by the generator, converting the AC power to direct current (DC) power, disabling output of the DC power during a first set of pre-selected conditions, limiting a rate of change of current of the DC power during a second set of pre-selected conditions, reducing conducted and radiated emissions of the DC power, disconnecting the DC power from the load under a third set of pre-selected conditions, and providing the DC power to the load.

Abstract: A modular assembly for a portable hemodialysis system may include a dialysis unit, e.g., that contains suitable components for performing hemodialysis, such as a dialyzer, one or more pumps to circulate blood through the dialyzer, a source of dialysate, and one or more pumps to circulate the dialysate through the dialyzer, and a power unit having a housing that contains suitable components for providing operating power to the pumps of the dialysis unit. The power unit may be selectively connected to the dialysis unit and provide power (e.g., pneumatic power in the form of pressure and/or to vacuum) to the dialysis unit for the pumps when connected to the dialysis unit, but may be incapable of providing power to the dialysis unit when disconnected from the dialysis unit. The dialysis unit and the power unit are sized and weighted to each be carried by hand by a human.

Abstract: A distillation device may comprise a source fluid input and an evaporator in fluid communication therewith. The device may further comprise a compressor having an impeller coupled to a motor, the compressor having a low pressure inlet for vapor from the evaporator and a high pressure outlet for compressed vapor. The device may further comprise at least one temperature sensor configured to monitor temperature of vapor in the inlet and a condenser in heat transfer relationship with exterior surfaces of the evaporator and in fluid communication with the compressor outlet. The device may further comprise a controller configured to govern rotation speed of the impeller with an impeller motor command based on a calibrated motor speed for the distillation device. The controller may be configured to determine an adjusted motor speed for a next use of the device and overwrite the calibrated motor speed with the adjusted motor speed.
