Abstract: A ground obstacle collision-avoidance system includes a plurality of radar sensor modules that each receive at a radar detector radar return signals corresponding to reflections of the emitted signal from a ground obstacle, and transmits radar information associated with the received radar signal reflections reflected from the ground obstacle, wherein each of the plurality of radar sensor modules are uniquely located on a surface of an aircraft that is at risk for collision with a ground obstacle if the aircraft is moving; a gateway unit that receives the radar information transmitted from the radar sensor module and transmits information associated with the received radar information; a processing system configured to determine a distance from the installation aircraft to a detected ground object detected; and a display configured to present a plan view indicating an aircraft icon and a graphical ground obstacle icon that is associated with the detected ground obstacle.

Abstract: In sonic examples, an obstacle detection system is configured to generate and display a graphical user interface (GUI) that includes an overhead image of an area in which a vehicle is positioned, a graphical representation of the vehicle, and graphical representations of one or more obstacles, The graphical representations of the one or more obstacles and vehicle can be arranged relative to the overhead image to indicate determined real-world positions of the one or more obstacles and vehicle, respectively, relative to other features shown in the overhead (e.g., airport structure or other buildings).

Abstract: A ground crew collision-avoidance system includes a plurality of radar sensor modules that each emit a radar signal, receives at a radar detector radar return signals corresponding to reflections of the emitted signal from a ground object, and transmits radar information associated with the received radar signal reflections reflected from the ground object, wherein each of the plurality of radar sensor modules are uniquely located on a surface of an aircraft that is at risk for collision with a ground object while the aircraft is being towed; a gateway unit that receives the radar information transmitted from the radar sensor module and transmits information associated with the received radar information; and a ground crew alert indicator that receives the information transmitted by the gateway unit and that presents a graphical alert icon on a display. The display indicates a likelihood of collision between the aircraft and the ground object.

Abstract: A controller includes a low power processor to couple to a sensor, the low power processor configured to receive data from the sensor and apply rules to the received data and provide an interrupt in accordance with the applied rules. A high power processor is coupled to receive interrupts from the low power processor in a sleep mode, to wake upon receipt of the interrupt, and to receive and process the data to determine actions to take based on the data, wherein the high power processor initiates the actions.

Abstract: A method, system, and apparatus for determining a corrective action for a diagnosable system are provided. A failure mode reasoning engine (FMRE) receives an evidence notification. The FMRE determines a plurality of evidentiary-failure-mode-probability rectangles (EFMPRs) based on the evidence notification. A candidate EFMPR in the plurality of EFMPRs is determined. The candidate EFMPR may be determined based on a distance from an origin of an evidentiary-failure-mode-probability graph. An overlap area is determined between the candidate EFMPR and the other EFMPRs in the plurality of EFMPRs. The overlap area is compared to an overlap threshold. If the overlap area is less than the overlap threshold, a reasoned failure mode (i.e., correct diagnosis) and/or a reasoned corrective action for the diagnosable system is determined, based on the candidate EFMPR. The FMRE may report and/or take the reasoned corrective action.
