Abstract: A dual-independent hybrid actuator system includes an actuator body defining a hydraulic chamber. The actuator system includes a hydraulic piston assembly, including a hydraulic piston disposed within the hydraulic chamber and dividing the hydraulic chamber into a first hydraulic sub-chamber in fluid communication with a first hydraulic fluid passage and a second hydraulic sub-chamber in fluid communication with a second hydraulic fluid passage. The actuator system further includes a piston rod mounted to the hydraulic piston that passes through the second hydraulic sub-chamber with a distal end that projects outward from the actuator body. The actuator system further includes an electric motor mounted to the actuator body, and a threaded axle mechanically coupled to a motor shaft of the electric motor. The threaded axle passes through the first hydraulic sub-chamber and engages with a threaded port formed in the hydraulic piston assembly.

Abstract: A gas turbine engine assembly may include a combustion chamber for igniting a fuel and air mixture that generates a core stream flow. The gas turbine engine may also include a hot section cowling for directing the core stream flow through the engine assembly. The hot section cowling may include an inside surface and an outside surface opposite the inside surface. The gas turbine engine assembly may additionally include a plurality of thermoelectric generator (TEG) assemblies that are thermally attached to the outside surface of the hot section cowling. Each TEG assembly may include a multiplicity of thermoelectric generator (TEG) devices that generate an electric current based on a temperature differential across each of the multiplicity of TEG devices. The TEG devices may include different materials that are used in different heat zones along the hot section cowling between the combustion chamber and an exhaust end of the engine.

Abstract: A battery management system (BMS) described herein determines the internal resistance for a cell that may have an internal short circuit. In one aspect, the BMS monitors the voltage across each of a plurality cells that are coupled in series. If the voltage across one of the cells differs from the voltages across the other cells, the BMS can flag the cell as potentially having an internal short circuit. Once flagged, the BMS can use a simulator that stores a model cell that has similar characteristics as the cells monitored by the BMS to determine the internal resistance of the flagged cell. In one aspect, the simulator changes the value of a surrogate resistor that is parallel with the model cell until the voltage across the model cell matches the voltage of the flagged cell. The value of the surrogate resistor indicates the internal resistance of the flagged cell.

Abstract: A method, apparatus, and computer program product is provided for configuring a microgrid. A first configuration of the microgrid having a set of microgrid elements is initialized. An address for each element in the set of microgrid elements of the microgrid is verified. In response to receiving status data from the set of microgrid elements connected in a peer-to-peer network indicating a reconfiguration of the microgrid, the set of microgrid elements is re-aligned to form a second grid configuration. The second grid configuration is executed.

Abstract: Increased DC-to-AC power conversion efficiency in a scalable, flexible, resilient, cascading inverter driver topology. Plural power cells, which include a rectifier and an inverter, are arranged in a series/parallel topology. Use of plural power cells increases efficiency by reducing voltage transition losses and by increasing duty cycle. Also, the power cells output AC to an electric motor using a forward-looking controller that responds to varying power demand while maintaining motor speed at a maximum efficiency level. Power output is varied by varying the width of rectifier output pulses to the inverters while maintaining pulse voltage. Transitions between power levels are smoothed by pulse density modulation. Pulse density, determined automatically in the inverter, begins high and gradually becomes less dense so voltage changes rapidly then slowing gradually. The topology and power cell components allow faulty power cells 10 to be isolated and bypassed.

Abstract: A system includes a battery and a power management unit connected with the battery. The power management unit controls power to the battery. A spare power unit can connect with the power management unit and the battery. The power management unit stores excess charge to the spare power unit and to divert stored charge to the battery when the battery is charged less than a determined percentage.
