An exterior aircraft light with cover erosion monitoring, the exterior aircraft light comprises: a support; at least one light source, arranged on the support; a light transmissive cover, arranged over the at least one light source, the light transmissive cover having a forward facing portion and a rear-ward facing portion; a first light sensor, arranged to receive light emitted by the at least one light source and reflected towards the first light sensor by the forward facing portion of the light transmissive cover; and a second light sensor, arranged to receive light emitted by the at least one light source and reflected towards the second light sensor by the rearward facing portion of the light transmissive cover.

A device includes a processor or integrated circuit package and at least one MEMS device coupled to the processor or integrated circuit package. The at least one MEMS device includes a first arm, a second arm, at least one permanent magnet, a fan structure, and a coil. The second arm is coupled to, and is spaced apart from, the first arm. The at least one permanent magnet is coupled to the first arm. The fan structure is coupled to, and extends in cantilever manner from, the second arm. The coil is disposed on or within the fan. Thus, when the coil is electrically energized, a Lorentz force is generated that causes the fan structure to vibrate relative to the at least one permanent magnet and relative to the processor, to thereby cool the processor or integrated circuit package.

Innovative peripheral bar assembly for a transportation vehicle is provided. The assembly includes a front bar housing with a front segment and a rear segment, and a through slot aligned with a diffuser operationally coupled to a first surface of an I/O PCB having a plurality of light sources emitting light that is transmitted through the diffuser and the slot. The assembly further includes a rear bar housing having a front segment and a rear segment, the front segment of the rear bar housing coupled to the rear segment of the front bar housing. A top surface of the peripheral bar assembly is coupled to a bottom of a chassis of a display system having a display module. The assembly configured to provide accent lighting through the slot of the front bar housing.

A system and a method for contactless power generation for a lighting arrangement configured on an aircraft propeller. Power is produced when a magnetic field produced by an arrangement of magnets on an airframe magnetically interacts with coils configured on an aircraft propeller. When the propeller spins, rotation of the mounted coils through the magnetic fields of the magnets generate power. Electrical wiring carrying charge from the coils to the lights is laid into grooves formed in propeller blades which connect to lights inserted in formed sockets.

An LED drone light of high power and very light weight has an LED circuit board cooled by a foamed metal matrix of copper or aluminum. Preferably bonded to a disc or puck which is thermally bonded to the back of the PCB, the foamed metal matrix can be cooled by a small fan attached to the light's housing.

An aircraft exterior light unit may comprise a magnetically controlled fluid drain valve configured to expel liquid water from the light unit. The valve may include a permanent magnet configured to induce a magnetic flux circuit that generates a magnetic force configured to close the valve. The valve may be configured to open when the pressure inside the light unit exceeds the magnetic force. As the valve opens and expels the water, the pressure within the light unit may decrease, equalizing with that of the external environment. As the magnetic force generated by the magnet increases as the valve is open and the water expelled, the magnet may be configured to close the valve once more. As such, the magnet may be configured to control a self-acting fluid drain valve in an aircraft exterior light.

An aircraft headlight comprises at least one light source and an integrated, single-piece optical structure. The integrated, single-piece optical structure includes a light transmissive protective cover portion, forming an outer light emission surface of the aircraft headlight, and at least one reflector portion, arranged for directing light that is emitted by the at least one light source through the light transmissive protective cover portion.

An exterior aircraft light comprises a housing defining an interior space; a light output generation unit comprising at least one light source; power supply electronics, coupled to the light output generation unit for driving a light out-put of the exterior aircraft light; and a draining device for draining the interior space. The draining device comprises a first drainage tube for receiving fluid, which is to be drained from the interior space; a second drain-age tube for receiving fluid, which is to be drained from the interior space; and a fluid discharge port for discharging fluid out of the housing, wherein the fluid discharge port is in fluid communication with the first drainage tube and with the second drainage tube. Each of the first drainage tube and the second drainage tube comprises a valve mechanism for selectively sealing and opening the respective drainage tube with respect to the interior space.

Systems and methods are disclosed for lighting a vehicle. A system includes a plurality of lights disposed on a vertical take-off and landing (VTOL) vehicle configured to turn on and off, change color, and/or change intensity. The system further includes a controller configured to determine a lighting scheme for the plurality of lights, the lighting scheme including a setting for the plurality of lights, the setting including one or more of turning the plurality of lights on or off, setting a color of the plurality of lights, and setting an intensity of the plurality of lights, determine a location in or associated with the VTOL vehicle, wherein the lighting scheme is configured to guide a person to the location, and transmit a signal to the one or more lights to execute the lighting scheme to guide the person to the determined location.

A light for mounting on an aircraft is fitted with a light source, an antenna for establishing radio communication between the aircraft and a ramp agent, or airport equipment, or an airport vehicle, and connection means for connecting a signal cable for linking the antenna to radio communication means of the aircraft.
