A lighting system for an aircraft including a light source configured to emit light and a refractive optical element configured to receive light from the light source and to redirect the light to produce light beams each directed to illuminate a specific surface of the aircraft or ground near the aircraft. The lighting system may be used in a method to monitor ice accretion on a surface of an aircraft.

Systems, devices, and methods for presenting information in the sky using drones are disclosed. The presentation of information includes navigating one or more drones to locations in the sky where the locations are associated with an image, emitting light signals at the locations, capturing the light signals with a user device, processing the captured signals to identify the image, capturing a background image including at least one of the locations associated with the image, and presenting simultaneously, on the user device, the identified image and the background image.

In some implementations, in an emergency in the vehicle, an emergency evacuation path is illuminated using the light emitted from the emergency evacuation rope where at least a portion of the emergency evacuation path extends to a location outside the vehicle. Egress of occupants along the emergency evacuation path is enabled using an emergency evacuation rope.

The invention relates to an airfield light comprising a body, a medium intensity lighting arrangement, and a high intensity lighting arrangement. The medium intensity lighting arrangement provides an omnidirectional light source, and the high intensity lighting arrangement provides a unidirectional or bidirectional light source. The invention is energy efficient compared to conventional airfield lights, and has particular application to temporary airfields. LEDs may be used as the light sources.

An intelligent rescue method applied to a vehicle-mounted device and an airborne rescue device to enable semi-automatic warning and rescue of a broken-down, crashed, drowned, or stranded vehicle, enables communication between the vehicle-mounted device and the rescue device. The vehicle-mounted device determines by sensors a type of emergency of a vehicle, and performs a first assistance action and sends the rescue device a distress signal corresponding to the type of the emergency of the vehicle. The rescue device receives the distress signal and takes off from an initial position of the vehicle to a target position in response to the distress signal. Once the rescue device reaches the target position, the rescue device performs a second action for assistance.
