Abstract
A of using an ultraviolet (UV) light emitter is disclosed herein. The method includes measuring, by a processor, a first distance from the UV light emitter to a target surface, activating, by the processor, the UV light emitter, and recording, by the processor, a second distance from the UV light emitter to the target surface. The method further includes calculating, by the processor, an accumulated dose of UV light on the target surface based at least in part on the second distance and deactivating, by the processor, the UV light emitter in response to the accumulated dose reaching a target dose.

A method of using an ultraviolet (UV) light emitter, comprising:
- measuring, by a processor, a first distance from the UV light emitter to a target surface;
- activating, by the processor, the UV light emitter;
- recording, by the processor, a second distance from the UV light emitter to the target surface;
- calculating, by the processor, an accumulated dose of UV light on the target surface based at least in part on the second distance;
- and
- deactivating, by the processor, the UV light emitter in response to the accumulated dose reaching a target dose.
A system for using an ultraviolet (UV) light emitter in an aircraft lavatory, comprising:
- a UV light source;
- an occupancy sensor;
- a UV light source driver including:
- a power source configured to power the UV light source;
- a processor;
- and
- a memory coupled to the processor, the memory comprising instructions when executed by the processor cause the processor:
- measure a first distance from the occupancy sensor to a target surface;
- activate the UV light source;
- record a second distance from the occupancy sensor to the target surface;
- calculate an accumulated dose of UV light on the target surface based at least in part on the second distance;
- and
- deactivate the UV light source in response to the accumulated dose reaching a target dose.
