A light assembly includes a housing, a light emitting diode (LED), and a hemispherical dome. The housing has a lens mounted thereon. The light LED is mounted within the housing and operable to emit light within a predetermined range of wavelengths and at an emission intensity toward the lens. The hemispherical dome mounted is within the housing between the LED and the lens. The hemispherical dome comprises a material that attenuates the emission intensity by a predetermined magnitude, and has an aperture formed therein and through which a portion of the light emitted from the LED may pass unattenuated.

An aircraft beacon light with integrated health monitoring comprises an annular arrangement of light sources, which are configured for repeatedly emitting beacon light flashes; a light detection sensor surrounded by the annular arrangement of light sources; and at least one reflective portion arranged to reflect light emitted by the annular arrangement of light sources onto the light detection sensor.

Provided is an unmanned aerial vehicle including: a discharge port configured to discharge contents in a container; an expansion/contraction unit configured to connect the discharge port and the container and be expandable; and a discharge position control unit configured to control expansion/contraction of the expansion/contraction unit.

A light assembly may comprise a heatsink, a plurality of light emitting diodes, and a lens. The heatsink may include a first surface and a second surface opposite the first surface. The second surface may define an airflow path extending from a first end of the heatsink to a second end of the heatsink. The plurality of light emitting diodes may be coupled to the first surface of the heatsink. The lens may be located over the plurality of light emitting diodes and may contact the heatsink.

Systems and methods for an aircraft lighting system (ALS) are provided. The method includes co-locating a central light source subsystem including a blue light generator, red light generator, and green light generator, and a light generating control unit (LGCU) comprising a processor, and distributing a plurality of passive light-heads around an external surface of the aircraft. Each passive light-head of the plurality of passive light-heads is operationally coupled to a first side of a respective light switch of a respective plurality of light switches, the light switch being coupled on a second side to a light emitting output of the central light source subsystem. Controlling and actuating the light generators and the light switches in accordance with a load profile is performed by a light generating control unit (LGCU).

Systems and methods for calibrating a synthetic image on an avionic display. The method includes receiving a synthetic image frame generated by an avionic display system and a sensor image frame from a forward-facing onboard sensor system. Object recognition is performed on the sensor image frame to generate a first search region for a first Federal Aviation Administration (FAA) marking, defined as a first search region-FAA marking pair. The sensor image frame and the first search region-FAA marking pair are processed using a deep learning method (DLM) to determine for the first FAA marking of the first search region-FAA marking pair, each of: a position deviation calculation, an orientation deviation calculation, and a synthetic image distortion factor. The synthetic image frame is then updated and rendered in accordance with the position deviation calculation, the orientation deviation calculation, and the synthetic image distortion factor, thereby calibrating the synthetic image frame.
