Abstract: An aircraft and method of deterring avian species from the aircraft include a lighting system including a lighting assembly coupled to the exterior. The lighting assembly includes an ultraviolet (UV) light-emitting element that emits UV light outside of the aircraft.

Abstract: In an example, a method of operating an ultraviolet (UV) light source includes providing a supply power to the UV light source, and activating, using the supply power, the UV light source to emit UV light during a series of activation cycles. The method also includes, during at least one activation cycle in the series, sensing the UV light emitted by the UV light source to measure an optical parameter of the UV light. The optical parameter is related to an antimicrobial efficacy of the UV light. The method further includes adjusting, based on the measured optical parameter, an electrical parameter of the supply power to maintain a target antimicrobial efficacy of the UV light over the series of activation cycles.

Abstract: A method for controlling a passenger service unit includes receiving, by a personal device of a passenger, an electromagnetic (EM) signal. The EM signal includes identification information of the passenger service unit. The method also includes transmitting, by the personal device, a message for controlling operation of one or more selected devices of the passenger service unit. The message includes an identification of the one or more selected devices of the passenger service unit and a control input for each of the one or more selected devices.

Abstract: A computing device determines whether or not to authorize a network request. In particular, responsive to the computing device receiving the network request from a mobile device, the computing device controls a plurality of light fixtures to each optically transmit a respective challenge code. The computing device approves or rejects the network request based respectively on whether or not a group of the challenge codes is received from the mobile device, each challenge code in the group being optically receivable at a location authorized for approving the network request.

Abstract: In an example, a system for disinfecting a lavatory in a vehicle includes a UV light source in the lavatory and configured to emit UV light when activated. The system also includes a switch actuatable between a first state and a second state. The switch is configured to: (i) while in the first state, provide an input power from a power source of the vehicle to a lavatory device in the lavatory, and (ii) while in the second state, provide the input power from the power source to the UV light source and cease providing the input power to the lavatory device. The system further includes an activation control system configured to actuate the switch between the first state and the second state to deactivate and activate the UV light source, respectively. The input power is insufficient to simultaneously operate the lavatory device and activate the UV light source.

A lavatory may include illuminating indicators; an illuminated, folding, baby changing station; a vanity; a self-cleaning toilet; and/or an illuminated faucet.

Abstract: A system and method for identifying seats within a mobile platform such as an aircraft, bus, ship, train, etc. A sensor subsystem detects when a door of the mobile platform is opened and transmits a wireless signal to each one of a plurality of projector subsystems. Each of the projector subsystems are disposed adjacent an associated seat of the mobile platform. Each projector subsystem projects an enlarged, optical signal with seat identifying information onto the seatback of its associated seat.
