  • Publication number: 20100172062
    Abstract: A solid state power control module contains non-volatile memory. A switch for opening is provided to break a supply of power to a component. The switch is operable to trip (open) when an undesirable condition is detected, and further to be opened upon receiving a control signal. A status of the switch is stored in the non-volatile memory. A detector is provided for identifying when a module has been mounted in a housing, and communicates with the non-volatile memory if it is determined that the module is newly installed in a housing. A system and method are also claimed.

  • Patent number: 7710228
    Abstract: An electrical inductor assembly comprises an inductor core having a circular shape, a wire guide that surrounds the inductor core and includes a plurality of slots, at least one of the slots forming a path winding around the inductor core, and at least one wire placed in one of the plurality of slots to form a winding. A method of forming an electrical inductor assembly comprises forming an inductor core having a circular shape, surrounding the inductor core with a wire guide, winding at least one wire around the inductor core along a slot in the wire guide, and applying an insulating material to the slot containing the at least one wire to electrically insulate the at least one wire.

  • Patent number: 5911388
    Abstract: The bleed air requirements for a pressurization and environmental control system for the cabin (10) of an aircraft may be reduced by a system that includes a turbomachine (20) having a rotary compressor (22) driven by a turbine wheel (26). A ram air inlet (16) is connected to the compressor inlet (28) and the aircraft is provided with a cabin air exhaust port (18) which is connected to the outlet (34) of the turbine wheel (26). A heat exchanger (40) has a cabin inlet air flow path (42) and a cabin outlet air flow path (44) in heat exchange with one another. The cabin inlet air flow path (42) is connected to the outlet (30) of the compressor (22) and to the cabin (10) of the aircraft. The cabin outlet air flow path (44) is connected to the cabin (10) as well as to the inlet (32) of the turbine (26).

  • Patent number: 5701755
    Abstract: Improved cooling of electronic heat loads aboard aircraft is achieved in a system including a sealable aircraft cabin (10), first and second electronic heat loads (38), (40) and a means (42) for maintaining a desired pressure within the cabin (10). A rotatable turbine wheel (16) is associated with an overboard dump port (32) such that air being dumped overboard from the cabin is expanded to rotate the turbine wheel (16). A mechanical load (20) is connected to the turbine wheel (16) for harnessing the rotation thereof and means (24), (60) are employed for using the air expanded by the turbine wheel (16) for cooling at least one of the loads (38), (40).
