Abstract: A motor assembly can include a motor shaft, a stator assembly, and a rotor assembly, and can include a cooling jacket. The cooling jacket can include an inner wall facing radially inwardly towards the stator assembly and an opposite outer wall facing radially outwardly, a circumferential internal fluid passageway for allowing a cooling fluid to be pumped through an interior of the cooling jacket, the internal fluid passageway being disposed between the inner and outer walls and extending between an inlet and an outlet, a mounting pad receiving, at an opening in the outer wall, a heat generating component associated with the motor assembly, the opening being in fluid communication with the internal fluid passageway such that the cooling fluid can provide cooling to the heat generating component.

Abstract: Systems and methods are described herein that improve grid performance by smoothing demand using thermal reserves. The smoothed demand can reduce peak loads as well as the ramp rate of demand that will otherwise require the use of inefficient, expensive generation sources. These improvements are tied to the selective switching on or off electrical loads that are coupled to thermal reserves, effectively using the thermal reserves as an energy storage mechanism. Historical data of past usage can be used to create load model and ensure that effects on customer comfort are minimized while still accomplishing the beneficial effects for the overall grid, which enables grid owners to both reduce their operational cost by avoiding expensive generation and improve system reliability by achieving more predictable power demand.

Abstract: A splice plate for a cable tray facilitates proper longitudinal spacing between first and second cable tray sections. The splice plate may include spacing indicia that indicates to a user longitudinal spacing between the longitudinal ends of the first and second cable tray sections when the splice plate is fastened to the first and second cable tray sections. The splice plate may include a window that allows at least one of the longitudinal ends of the respective first and second cable tray sections to be visible when the splice plate is fastened to the first and second cable tray sections. The splice plate may include a machine readable marking including a machine readable representation of a web address that directs a hand-held device including a processor to a webpage including instructions for using the splice plate.

Abstract: In one embodiment, a lifter assembly comprises a lifter having a latching mechanism, a slot arranged on an outer wall of the lifter and comprising an inlet that provides access to the latching mechanism, and a pin comprising a fluid channel. The latching mechanism is switchable between a latched position and an unlatched position. The pin is configured to interface with the slot such that the lifter is prevented from rotation about a lifter axis. The fluid channel is configured to be fluidly coupled to the inlet of the slot.

Abstract: Arc fault detection modules for vehicles intended to supervise circuits and detect arc fault conditions in both alternating current and direct current circuits. A number of these arc fault detection modules may be integrated into a vehicle's electrical system in strategic locations. Each arc fault module contains sensing capabilities for monitoring the circuit, and may also include signal conditioning capabilities, processing capabilities for determining the occurrence of an arc fault, contactors for disabling the supervised circuit, and communications capabilities to interact with other vehicle components and telematics systems. As a result arc fault detection odules can be customized to leverage existing features of a vehicle's electrical system or to provide fully redundant arc fault protection.

Abstract: An aircraft fuel tank inerting system may include at least one fuel tank, at least one surge tank, an inert air assembly, at least one fluid valve connected to the at least one fuel tank, the at least one surge tank, and the inert air assembly, and/or an electronic control unit. The electronic control unit may control the at least one fluid valve to provide inert air from the inert air assembly to the at least one fuel tank and/or to the at least one surge tank. The electronic control unit may control the at least one fluid valve to provide inert air from the inert air assembly to the fuel tank during a climb phase of a flight and control the at least one fluid valve to provide inert air from the inert air assembly to the at least one surge tank during a descent phase of the flight.

Abstract: A thermal management system enables fluid coupling of the cooling circuits for the battery and the propeller arrangements. More than one propeller arrangement can be serviced by the same cooling circuit, but distribution of the coolant may be finessed. Optional pathways are provided to use heated coolant for heating (e.g., de-icing, cabin heating, etc.) before cooling the coolant. Fluid coupling of conduits between and/or within the cooling circuits provide redundancy to accommodate various faults and equipment malfunctions.

Abstract: A method to provide power to a control supporting circuit includes connecting an optical power converter to the control support circuit, the optical power converter connected to a laser source via a fiber optic cable, controlling, by a controller, a laser source driver to drive a laser source providing a laser and the control supporting circuit; and supplying power to the control supporting circuit by irradiating the optical power converter with the laser via the fiber optic cable. A stray capacitance between the controller and the high voltage supporting circuit is reduced to zero or nearly zero. A method of shutting down a laser source driver providing laser energy to an optical power converter is also provided.

Abstract: A harmonic suppression method and apparatus for a three-phase three-wire cascaded power conversion apparatus is disclosed. The method can include: calculating a first current output from a full-bridge rectifier module to a floating direct current side, the first current being composed of a first current direct current component and a first current double frequency component; and generating a first injection voltage with a triple frequency, so as to inject the first injection voltage into the floating direct current side and transfer at least a portion of the first current double frequency component to a low-voltage direct current side, where total current on the floating direct current side is composed of the first current and a second current after the first injection voltage is injected, the second current is composed of a second current double frequency component and a second current quadruple frequency component, and the amplitude and the phase angle of the first injection voltage are configured so that the first and second current double frequency components are at least partially canceled. The method reduces the demand for capacitance on the floating direct current side of the power conversion apparatus, resulting in a significant increase in power density and high power conversion efficiency.
