Abstract: Technology provides for controlling a high-energy management system for an aircraft that includes receiving sensor data from a plurality of high-energy (HE) systems, wherein each of the plurality of HE systems is located in an aircraft, determining a present state of each of the plurality of HE systems based on the sensor data, determining a target state of each of the plurality of HE systems based on the present state of each of the plurality of HE systems and a set of HE system rules, and automatically generating one or more control actions to effect control of one or more of the plurality of HE systems based on the target state of each of the plurality of HE systems. Examples further include receiving a schedule of tasks to be performed on the aircraft, where determining the target state is further based on the schedule of tasks.

Abstract: An apparatus and method for active cancellation of interference at a hearing assistive devices are presented. The apparatus includes an interference cancellation circuit for cancelling an interference component of a composite signal, and an activator circuit for enabling interference cancellation circuit. The interference cancellation circuit generates an estimated replica of the interference from an interference profile, inverts the replica to form a cancellation waveform, then adds the cancellation waveform to the composite signal to cancel the interference component. An interference profile can be provided by performing a training sequence on a composite signal to detect a repetitive signal and building a profile using its parameters, retrieving a profile stored in memory, or using an antenna to capture an RF signal.

Abstract: A method and apparatus which provide for simultaneously monitoring and controlling multiple consumer devices located in a fixed and/or mobile environment includes a handheld RF communications device having multiple controls. In addition, a transceiver device is provided which simultaneously a) receives output signals from selected ones of the consumer devices and transmits the received output signals as radio frequency signals to the handheld communications device, and b) receives control signals from the handheld communications device, and relays the control signals to an associated consumer device to control the associated consumer device.

Abstract: An insulation system for the fuselage walls of an aircraft. The insulation is a formed-in-place, sprayed-on foam that is applied against a barrier material that is draped against the inside of the exterior skin of the fuselage and over any inwardly projecting structural members attached to the exterior skin. No substantial portion of the barrier material passes underneath any laterally projecting portions of the structural members, so that the subsequently solidified, semi-flexible foam (i.e. insulation) can be removed at a later time for necessary inspections of the aircraft, without being trapped behind these lateral projections. The foam is preferably fire retardant and hydrophobic. An additional protective layer may also be sprayed on to the outside surface of the insulating foam.

Abstract: The present invention encompasses a system and method for insulating an aircraft passenger cabin from ambient temperatures without the need for insulation blankets. Hot bleed air flowing through a network of fluid passageways is directed into sealed bays formed between the outer skin of the fuselage and the wall panels of the passenger cabin. As the hot bleed air rises through the sealed bays, it insulates the interior of the passenger cabin from the outside ambient temperatures. The outer skin of the aircraft acts as a heat exchanger by removing heat from the bleed air before it is introduced into the cabin. The bleed air maintains the cabin at a comfortable temperature without the need for air conditioning when the aircraft operates at high altitude.
