Abstract: A non-isolated power supply is configured to receive an input voltage and supply an output voltage, and includes a supply line, a return line, a first semiconductor switch coupled in series in the supply line, and a second semiconductor switch coupled in series in the return line. The first and second semiconductor switches are each configured to operate in an ON state and an OFF state. The differential current sensor is configured to sense differential current between the supply line and the return line. The fault detection logic is coupled to the differential current sensor, the first semiconductor switch, and the second semiconductor switch, and is configured to detect when the differential current exceeds a predetermined current magnitude, and command the first and second semiconductor switches to operate in the OFF state upon detecting that the differential current exceeds the predetermined current magnitude.

Abstract: Vehicle systems and methods are provided for visually alerting a vehicle operator to a potential obstacle in the vicinity of a vehicle using an external lighting system associated with the vehicle. An exemplary method involves identifying an analysis portion of image data captured for a region external to the vehicle based at least in part on current status information associated with the vehicle, identifying an obstacle within the analysis portion of the image data based at least in part on ranging data for the analysis portion, and in response to identifying the obstacle, automatically adjusting an illumination axis associated with a lighting system to illuminate the obstacle, determining a current value for a contrast ratio associated with the obstacle relative to the analysis portion of the image data, and automatically adjusting one or more characteristics of the lighting system based at least in part on the current value.

Abstract: An aircraft collision avoidance system includes a plurality of three-dimensional (3D) light detection and ranging (LIDAR) sensors, a plurality of sensor processors, a plurality of transmitters, and a display device. Each 3D LIDAR sensor is enclosed in an aircraft exterior lighting fixture that is configured for mounting on an aircraft, and is configured to sense objects within its field-of-view and supply sensor data. Each sensor processor receives sensor data and processes the received sensor data to determine locations and physical dimensions of the sensed objects. Each transmitter receives the object data, and is configured to transmit the received object data. The display device receives and fuses the object data transmitted from each transmitter, fuses the object data and selectively generates one or more potential obstacle alerts based on the fused object data.

Abstract: A control system in a UVC-based aircraft sanitization system for controlling the UVC-based aircraft sanitization system to maintain a desired UVC (ultraviolet C) radiation level at a target surface in an aircraft under varying operating conditions is disclosed. The control system includes a controller configured to: receive measured radiation feedback from a radiation measurement device (e.g., dosimeter) on the target surface that identifies a radiation level that is applied at the target surface by the UVC-based aircraft sanitization system; and generate a UVC source control command for UVC sources in the UVC-based aircraft sanitization system. based on the received measured radiation feedback, to control the UVC sources to increase or decrease radiation level output (e.g., identify the amount of increase or decrease from the UVC sources) to generate sufficient radiation to achieve the desired radiation level at the target surface.

Abstract: Provided systems and methods for an aircraft lighting system (ALS) include a centralized blue generator that supplies blue light to a plurality (N) of passive light-heads distributed at various locations on the aircraft. A load profile for use of the N passive light-heads during all flight phases and operational phases is developed and uploaded into the system. Each of the passive light-heads is operationally coupled to the blue light generator via a respective light transmission element that is gated with a respective one of N light switches. A light generating control unit (LGCU) is coupled to the blue light generator, and controls the generation and actuation of blue light, in addition to controlling light switch positions, as a function of navigation data and the load profile. Each of the N passive light-heads comprises a respective light conversion element to convert the blue light into red, green, or white light.

Abstract: A spherical electromagnetic machine includes a spherical stator, a plurality of longitudinal slots, a plurality of latitudinal slots, a plurality of longitudinal coils, a plurality of latitudinal coils, a first hemispherical shell rotor, and a second hemispherical shell rotor. The longitudinal slots and latitudinal slots are formed in, and are spaced evenly around, the outer surface. The longitudinal coils are disposed within a different one of the longitudinal slots. The latitudinal coils are disposed within a different one of the latitudinal slots. The first and second hemispherical shell rotors are mounted for rotation relative to the spherical stator body and have magnets on their inner surfaces. A Lorentz force causes movement of the first and second hemispherical shell rotors when electrical current is supplied to one or more of the longitudinal coils or to one or more of the latitudinal coils.
