The gas path being in communication with an exit in the container. The cavity including an opening receiving a gas accumulating within the cavity, the gas path allowing the accumulating gas to escape through the exit once the accumulating gas reaches a predetermined level proximate the trap portion.

Abstract: A system and method for autonomous distress tracking of an aircraft. An automatic dependent surveillance-broadcast transceiver is configured to transmit an automatic distress transmission. A system controller comprises a distress identifier that is configured to determine when the aircraft is in a distress condition. The system controller is configured to control the automatic dependent surveillance-broadcast transceiver to transmit the automatic distress transmission in response to a determination that the aircraft is in the distress condition. The automatic dependent surveillance-broadcast transceiver and the system controller are contained within a housing attached to the aircraft on an outside of the aircraft.

Abstract: A wastewater treatment system includes a blower providing air to an aerator and a low pressure pulsed air mixer. The invention generally relates to a wastewater treatment system and more particularly to a wastewater treatment system to eliminate biological and nutrient contaminants from wastewater.

Abstract: A system for wastewater treatment includes a container placeable in the fluid within a wastewater treatment vessel. The container comprises an inlet into which fluid from the treatment vessel can flow. In operation, compressed air is provided to aerate fluid within the container and vented from the container in such a way that fluid in the vessel external to the container does not receive aeration. Substrate within the container provides biomedia for treating wastewater. The user controls the operation of a pump that transports fluid from inside the container into fluid in the vessel external to the container. Concomitantly, fluid from outside the container flows in though the container's inlet. Thereby, the system continuously treats wastewater with aeration, intermixing treated and untreated wastewater.

Abstract: A method and an apparatus for deploying flight data from an aircraft. A bag is stored in a deflated state on the aircraft. The flight data is stored on a memory device coupled to the bag. The bag is inflated from the deflated state to the inflated state in response to a pressure level greater than a threshold pressure level to deploy the bag with the memory device coupled thereto from the aircraft.

Abstract: An example method for modifying a flight path of an aircraft includes receiving real time positioning estimates for an aircraft, receiving an actual navigation performance (ANP) of the aircraft informative of uncertainty in the position estimate, receiving a required navigation performance (RNP) instrument flight procedure for the aircraft, receiving spacing input from an air traffic controller that indicates spacing requirements between the aircraft and one or more other aircraft, receiving information relating to communities underneath the flight path, calculating, by a system onboard the aircraft, a modification to the flight path to be flown by the aircraft that causes the aircraft to remain within the containment boundaries of the RNP instrument flight procedure while reducing noise impact to the communities underneath the flight path and meeting the spacing requirements of the air traffic controller, and displaying a visual representation of a modified flight path for the aircraft.

Abstract: An example method for aircraft traffic spacing and timing control with flight path variation of an aircraft includes receiving information of aircraft traffic for an area, determining an aircraft spacing plan for the aircraft traffic for the area based on spacing requirements due to separation standards or flow management constraints for the aircraft traffic, determining that a modification to a flight path of an aircraft is required to meet a longitudinal spacing requirement between the aircraft and one or more additional aircraft of the aircraft traffic based on the aircraft spacing plan, determining a flight path modification to the flight path for the aircraft based on the modification that causes the aircraft to remain within associated margins of the RNP instrument flight procedure and alters the longitudinal spacing between the aircraft and the additional aircraft of the aircraft traffic, and assigning the flight path modification to the aircraft via a data communication link.

Abstract: An example method for flight path variation of an aircraft for noise management includes receiving noise inquiries of a community related to aircraft noise during flight over the community, receiving an output from noise sensors positioned within the community, determining a noise distribution plan for additional aircraft flying over the community so as to steer the additional aircraft and distribute additional aircraft noise in response to the noise inquiries and the output from the noise sensors, and based on flight path data of the additional aircraft and the noise distribution plan, assigning a flight path modification to aircraft via a data communication link. The flight path modification informs the aircraft to adjust the flight path to remain within associated margins of a required navigation performance (RNP) instrument flight procedure and to reduce noise impact to the community underneath the flight path.

Abstract: A method, apparatus, and aircraft tracker system for reporting state information for an aircraft. A state of the aircraft is identified using sensor data received from an aircraft sensor system in the aircraft. The state information is transmitted at a reporting rate set using the state of the aircraft identified from the sensor data, at least one of a crew command or a ground command when at least one of the crew command is received from a crew interface or the ground command is received from a ground source, and a policy defining priorities for reporting that are based on at least one of the crew command, the ground command, or the state of the aircraft identified from the sensor data.
