    Abstract: A gate drive topology and gate drive power supply topology designed to allow for a single Printed Wiring Board (PWB) design to be configured for two applications. In one application, select paired locations of solder pads or connector locations in the circuitry are populated with connecting “spanning” resistors for integration within the gate driver and gate driver power supply topologies. The physical manifestation of these resistors on the PWB allows paralleled gate drive switching of corresponding power transistor devices for driving a load. A common gate-source voltage is applied to all three gates and the switching devices share dynamic switching and conduction loss. In an alternate application, the select paired locations are not populated with spanning resistors thereby rendering a circuit topology permitting independent operation independent power transistor gate driving switching operations. The path across the unpopulated spanning resistors provides a high voltage creepage isolation between independent gate driver circuits.

    Abstract: A method for initializing an engine control system of an aircraft may include authenticating a boot loader, authenticating a manifest in response to authentication of the boot loader wherein the manifest contains hashes of one or more software components, and in response to authentication of the manifest, loading a first set of software components from among the one or more software components onto a non-transitory computer-readable medium, calculating a hash of each software component of the first set of software components, authenticating the first set of software components by comparing the calculated hash of each software component of the first set of software components to the hash of a corresponding software component in the manifest, and executing the first set of software components in response to authentication of the one or more software components. Devices and systems are also provided for initializing an engine control system of an aircraft.

    Abstract: A system for controlling load sharing between multiple generators mechanically coupleable to the output shaft of a prime mover is provided. The system may comprise a first processor; and at least two inverters operably connectable to at least two generators, respectively. The generators provide AC power to the respective inverter and each inverter provides DC power to a respective DC link. Each inverter may comprise a processor configured to control a respective generator. The processor may be configured to receive a common speed command from the first processor, adjust the common speed command based on a speed of the same output shaft to create a droop, determine a torque command based on the adjusted speed command and supply the determined torque command to the corresponding generator.

    Abstract: An apparatus that allows for access to any and all registers of a central processing unit in a line replaceable unit (LRU) without a need to open the housing of the LRU is provided. The apparatus may receive write or read packets from an external device and relay the same to an LRU. The apparatus may receive state information from one or more registers of the LRU in response. The apparatus may transmit or transfer the state information to an external device. The apparatus may be used to update firmware in the LRU, for diagnostics or testing.

    Abstract: A heat sink assembly includes a thermally conductive support member configured to be attached to a heat source and a heat sink. An adjustable mechanism is configured to moveably connect the thermally conductive support member to the heat sink. The adjustable mechanism permits the heat source to be moved relative to the heat sink without requiring access to the adjustable mechanism. The heat sink assembly provides a mechanically adjustable and supportive system having a thermally conductive path for heat removal from the object. The integral movable adjustment mechanism permits the thermally conductive member to translate without loss of the thermal path between the two ends. The heat source can move and become rigidly fixed in location without direct access. A compression mechanism may provide a continuous force between the support member and the heat sink as the support member is translated to permit movement of the heat generating source.

    Abstract: An insulator interface serves as both an insulator and the forming tool for a busbar. The busbar insulator interface includes a hollow riser having at least one channel extending between first and second openings at opposite ends of the riser, a busbar forming section located at one of the first and second openings of the riser and a terminal locating section extending from the busbar forming section, wherein the busbar forming section is configured for folding a busbar onto the terminal locating section. A busbar assembly includes a combination of a single piece busbar and an insulator interface. The busbar has one end pre-formed and other end straight to allow the busbar to pass through the insulator interface. The busbar insulator interface is designed to act as the forming tool with the proper bend radius for the busbar.
