Abstract: Systems and apparatus to generate electrical power from aircraft engine heat are described herein. An example aircraft engine described herein includes a gas turbine engine having an engine housing. The engine housing defines a flow path through a combustion chamber and a core exhaust cavity. The example aircraft engine also includes an energy-generating cell coupled to a portion of the engine housing defining the core exhaust cavity. The energy-generating cell is to generate electrical energy from high temperature fluid in the core exhaust cavity.

Abstract: A system for delivering oxygen enriched air to a selected location on an aircraft may include: a gas separation system configured to output a flow of the oxygen enriched air; an environmental control system configured to output a flow of conditioned air; and/or first, second, and third ducts. The first duct may be configured to direct the flow of the oxygen enriched air to the third duct. The second duct may be configured to direct the flow of the conditioned air to the third duct. The conditioned air and the oxygen enriched air may be mixed in the third duct. The third duct may be configured to direct the mixed conditioned and oxygen enriched air to at least one dispensing station at the selected location that is configured to dispense the mixed conditioned and oxygen enriched air to users of the at least one dispensing station.

Abstract: Systems and methods provide for a nitrogen generation and oxygen distribution system. According to one aspect, the system includes an NGS and an oxygen distribution processor coupled to the NGS. The NGS creates nitrogen enriched air as the primary product for fuel tank use, and oxygen enriched air as a secondary product. The oxygen distribution processor is operative to determine a number of flight parameters, and from those parameters, provide an oxygen distribution command to an oxygen distribution valve in order to prevent the oxygen enriched air from being distributed, to route the oxygen enriched air to the ambient environment, or to route the oxygen enriched air to an aircraft engine to increase combustion efficiency.

Abstract: A system and method for a customized ambient lighting environment for individuals in vehicles travelling rapidly across multiple time zones, that can be automated and/or based on user input and which allows each user to be exposed to light in accordance to selected preferences and circumstances, in order to begin acclimating the user to a new time zone, or avoid acclimating to a new time zone, and/or otherwise mitigate circadian desynchrony.
