A lighting system for use with evacuation systems for aircraft during emergency situations. The lighting system has a chasing or running light rhythm that provides the image of lights moving down the system to help provide clarity to the evacuees about the direction of descent.

A system for monitoring traffic in aircraft cabins includes conductive wire in aisle carpeting and sensors to register pressure via capacitance changes. The system identifies the volume and location of traffic in aircraft aisles via registered changes to voltage, current, and/or conductivity of the conductive wire, and sensors embedded in the carpet. Measurements over time establish changes in traffic flow and directionality which may be used to direct crew members in flight. Lighting elements may be incorporated into the carpet to provide signals to passengers and crew via the lighting elements.

A drone identification system including a drone having an LED “license plate” and an identification device is disclosed. The drone's LEDs emit a color pattern signal that is captured by the identification device, which is then used to uniquely identify the drone. Specifically, the identification device translates the color pattern signal into a unique identification code that is used to identify the drone. The identification code may be transmitted to a server to store the identification information in a directory for future use.

Technologies for drone-based cameras to detect proper wind direction for landing are described. One aerial vehicle can determine that it is in a vertical take-off and landing (VTOL) orientation and capture an image of a landing-pad device using the camera. The aerial vehicle can detect a visual marker in the image and can determine a wind direction, at a location of the landing page, from the visual marker. The wind direction is used by a propulsion subsystem to align the aerial vehicle into the wind direction for landing.

Airfield taxiway lights are described herein. One device includes a plurality of light sources, a plurality of prisms through which light emitted by the plurality of light sources is configured to pass, wherein the light emitted by each respective light source passes through a different one of the plurality of prisms, and a cover having a plurality of openings through which the light that passes through the plurality of prisms is configured to exit the airfield taxiway light, wherein each respective opening is positioned over a different one of the plurality of prisms.

Interior panels for interiors of aircraft, aircraft, and methods from making interior panels for interiors of aircraft are provided. In one example, the interior panel includes an outer covering that has a first surface. The first surface is configured to be exposed to the interior of the aircraft. A second surface is disposed opposite the first surface. The second surface has a first pattern formed therein that is hidden from the first surface. A first light source is operative to generate a first light and is disposed adjacent to the second surface generally aligned with the first pattern. When the first light source generates the first light, a first illuminated pattern corresponding to the first pattern formed in the second surface is visible on the first surface.

Disclosed are embodiments of exterior aircraft assemblies integrating compatible elements. In one example, an integrated aircraft assembly includes an aerodynamic housing attachable to an aircraft, an antenna system including at least one antenna element housed within the aerodynamic housing, and a lighting system including at least one light fixture housed within the aerodynamic housing. The at least one antenna element and the at least one light fixture may be co-located within then housing or mounted separately on the housing.

An aircraft lamp includes a light source unit, a lamp housing that houses the light source unit, and a power supply control unit that has a casing and includes a control circuit structure configured to control light emission of the light source unit. The control circuit structure is housed in the casing. The casing is disposed outside the lamp housing.

An air duct system comprising an air duct having a main body, a visible light source, an emitter configured to emit radio frequency waves, and one or more antennas. The main body of the air duct defines a passageway having a reflective inner surface. The visible light source is configured to generate visible light. The visible light source directs the visible light along the reflective inner surface of the air duct. The emitter directs the radio frequency waves along the reflective inner surface of the air duct. The one or more antennas are each connected to a corresponding power harvesting circuit, where the radio frequency waves are received by the one or more antennas and are converted into electrical power by the corresponding power harvesting circuit.

A replaceable light head for an exterior aircraft light includes a mounting structure for attaching the replaceable light head to the exterior aircraft light; a power terminal, coupleable to an internal power supply of the exterior aircraft light; at least one light source, coupled to the power terminal for receiving power from the internal power supply of the exterior aircraft light; a data interface, coupleable to a controller of the exterior aircraft light; and a memory, coupled to the data interface and configured to receive and store usage data of the internal power supply of the exterior aircraft light.
