A power management system and method for a vehicle includes a plurality of ultraviolet (UV) light sub-systems within an internal cabin of the vehicle. A power management control unit is in communication with the plurality of UV light sub-systems. The power management control unit is configured to adaptively control power supplied to the plurality of UV light sub-systems based on power usage data. The power supplied to the plurality of UV light sub-systems changes. The power usage data includes information regarding adaptable power requirements for the plurality of UV light sub-systems.

A longitudinal translatable seal includes a first compartment extending in a longitudinal direction; a second compartment extending in the longitudinal direction forming a sealing surface with the first compartment; and a carriage translatable longitudinally with respect to the sealing surface, and a port in the carriage to fluidly connect a first side of the seal with a second side of the seal.

A method and apparatus for cleaning surfaces of an object. A platform may be moved along a path relative to the object using a robotic device. A liquid may be applied onto the plurality of surfaces of the object using an applicator associated with the platform. The liquid may be worked into the plurality of surfaces using a plurality of cleaning elements associated with the platform to dislodge undesired material from the plurality of surfaces. A plurality of flexible members may be moved along the plurality of surfaces to dry the plurality of surfaces and remove the undesired material from the plurality of surfaces. An airflow may be generated that moves the undesired material into a vacuum duct in a vacuum system.

An occupancy detection system and method for an enclosed space includes a door sensor operatively coupled to a door of the enclosed space. The door sensor is configured to output a door sensor signal that indicates a status of the door. At least one presence sensor that is configured to output at least one presence sensor signal that indicates an occupancy status of the enclosed space. An occupancy detection control unit is in communication with the door sensor and the at least one presence sensor. The occupancy detection control unit is configured to receive the door sensor signal and the presence sensor signal(s). The occupancy detection control unit is configured to determine an occupancy status of the enclosed space based on the door sensor signal and the presence sensor signal(s).

A system for providing and monitoring UV illumination in an interior of an aircraft includes at least one switchable UV light source; a light detector, responsive to visible light and UV light and configured for providing sensor outputs regarding detected light; and a controller for monitoring an operational status of the at least one switchable UV light source. The controller is configured to determine the operational status of the at least one switchable UV light source by comparing a first sensor output, provided by the light detector when the at least one switchable UV light source is activated, with a second sensor output, provided by the light detector when the at least one switchable UV light source is deactivated.

A method of verifying sanitization of an area may comprise: emitting, via a sanitization system, a UV-C light towards a desired surface to be sanitized, the UV-C light including a first wavelength between 200 nm and 280 nm; and determining the desired surface is being sanitized by verifying whether the desired surface absorbs the UV-C light and re-emits a visible light.
