A system for monitoring pressure change within at least one compartment of an aircraft is provided. The system includes a primary pressure sensor for providing a signal corresponding to a pressure within a primary compartment of the aircraft, a primary monitoring channel coupled to the primary pressure sensor, and an output driver coupled to the primary monitoring channel. The primary monitoring channel includes a band pass filter for receiving and filtering the primary pressure signal, a pressure change circuit for determining a change in the filtered pressure signal and for providing a pressure change output signal corresponding to the change in pressure, and a threshold logic circuit for determining whether the pressure change output signal meets a predetermined threshold and for providing a threshold output signal indicating that a decompression event has occurred if the pressure change output signal meets the predetermined threshold. The output driver receives the primary threshold output signal and outputs a notification signal.

Rapid decompression detection system and method

A method and apparatus for an automated waste receptacle includes a waste flap, a motor positioned on a side of the waste flap and an actuator located in proximity of the top side of the waste flap. The actuator is configured to operate the motor and subsequently move the flap between open and closed positions.
