  • Thermal conditioning for air separation modules
    Patent number: 9089813
    Abstract: Thermal conditioning for an area surrounding one or more air separation canisters includes directing the exhaust gas of the thermal conditioning unit to the area surrounding the canisters. The area may be defined by a housing in which the canisters are positioned.
    Type: Grant
    Filed: July 8, 2010
    Date of Patent: July 28, 2015
    Assignee: Carleton Life Support Systems, Inc.

  • Architecture for dual source electric power generating system
    Patent number: 8358111
    Abstract: A dual source electric power generating system (EPGS) provides both a regulated AC output and a regulated DC output. The EPGS includes a rotating portion and a stationary portion. The stationary portion includes a plurality of windings (permanent magnet generator (PMG) armature windings, an exciter field winding, and high-voltage main generator armature windings), a voltage regulator, a rectifier, an inverter, a point of regulation (POR) sensor. The high-voltage main generator armature windings generate a high-voltage AC that is converted to a regulated, high-voltage AC by the rectifier and the inverter. The stationary portion is further characterized by circuitry for producing the regulated DC output from AC voltage produced by a winding other than the high-voltage main generator armature windings.
