Abstract: A system and method for heating and cooling a battery. The system includes a thermoelectric device configured to attach to the battery and operate in a heating mode to elevate the operating temperature of the battery and in a cooling mode to reduce the operating temperature of the battery. Control circuitry is configured to: determine a temperature of the battery; supply an input voltage and a polarity of the thermoelectric device; and adjust the input voltage and the polarity based on a temperature of the battery.

Abstract: An ice protection system for an aircraft includes one or more heaters configured to be coupled to a surface of a wing of the aircraft. The ice protection system also includes a controller configured to, in response to a first determination indicating presence of an icing condition, determine a setpoint temperature for a first location of an outer surface of the wing configured to be heated by a heater of the one or more heaters. The controller is also configured to control power provided to the heater based on the setpoint temperature. The setpoint temperature for the first location is determined to cause a second location of the outer surface of the wing, which is heated by the heater and is located at a particular distance from the first location, to remain above a threshold temperature based on a projected temperature profile of the outer surface heated by the heater.

Abstract: The advantageous embodiments provide a method, a computer program product, and an apparatus for monitoring a wiring system. A number of responses to signals transmitted in a portion of the wiring system are measured to form a measured signature. Design data for the portion of the wiring system is retrieved. A number of expected responses for the signals in the portion of the wiring system are identified using the design data to form a computed signature. The measured signature is compared with the computed signature.
