Abstract: An integrated circuit assembly element formed via an additive manufacturing technique, such as mixing a conductive material with a memory metal to form a portion of a substrate in desired locations, such as along the footprint of die, are discussed herein. In operation (e.g. in response to thermal cycling of the assembly) the memory metal contracts while the conductive material expands. The result is an element having reduced thermal expansion, which can be net zero coefficient of thermal expansion and/or be catered to the coefficient of thermal expansion of a desired material, such as the silicon die.

Abstract: A method of detecting electrical arc damage includes receiving input indicative of electrical power as a function of time in an electrical arc. The method includes using the input to model an amount of damage caused by the electrical arc, and comparing the amount of damage to a predetermined threshold. The method includes flagging a warning in response to the amount of damage exceeding a predetermined threshold. The method can include breaking a circuit to stop the electrical arc. Flagging the warning can include signaling to an operator to inspect a unit potentially damaged by the electrical arc. The method can include inspecting the unit potentially damaged by the electrical arc.

Abstract: In accordance with at least one aspect of this disclosure, a system includes an airflow line, a main compressor disposed in the airflow line configured to receive a ram air flow and supply a compressed air flow to the air flow line, and a motor operatively connected to drive the main compressor. An air cycle machine is disposed in the airflow line downstream of the main compressor configured to receive the compressed airflow and supply a cooled cabin airflow to an aircraft cabin. A cooling line tap disposed in the airflow line downstream of the air cycle machine configured to communicate a flow of cooling air to the motor from the airflow line to supply a portion of the cooled cabin airflow to one or more portions of the motor as motor cooling air via a first cooling airflow line.

Abstract: A system for cooling a motor operating within an aircraft system includes an enclosure receiving ram air from a first ram air duct and discharging ram air to a second ram air duct to form a cooling path. The second ram air duct is discrete and independent from the second ram air duct. The system can discharge ram air between a heat exchanger and a fan within the second ram air duct that define a reduced or negative pressure region within the second ram air duct.

Abstract: A power feeder device can include a base having a mounting portion and a plurality of connector structures extending from the mounting portion and spaced apart relative to each other to form a respective gap therebetween. Each connector structure can be configured to receive a respective pair of terminals to electrically connect the respective pair of terminals within connector structures and to block a line of sight between an adjacent pair of terminals. The device can also include a cover configured to mate with the base to enclose each of the plurality of connector structures and to increase a length of a creepage path between each pair of terminals by at least partially inserting into each gap between the connector structures. The base and the cover can be configured to form a terminal opening on each lateral side when assembled to allow pass-through of a conductor and/or portion of each terminal.

Abstract: A hydrogen fueled power system of a vehicle includes a liquid hydrogen fuel source having a volume of liquid hydrogen fuel and a thermal engine configured to expand the liquid hydrogen fuel into gaseous form via interaction between a heated first portion of the hydrogen fuel and a second portion of the hydrogen fuel. A heat exchanger is positioned between the liquid hydrogen source and the thermal engine, and is configured to heat the first portion of the hydrogen fuel via thermal energy exchange with a relatively warm fluid. A turbine is located fluidly downstream of the heat exchanger and upstream of the thermal engine, and is driven by the heated first portion. A power generator is located fluidly downstream of the thermal engine. The power generator utilizes exhaust from the thermal engine to generate electrical or mechanical power. A compressor is operably connected to and driven by the turbine.
