Mobile disinfectant device and methods
First Claim
1. A mobile device that provides ultraviolet light for sanitizing or sterilizing a target surface that comprises:
- an ultraviolet light source, a distance detector that measures a distance from the device to the target surface, an indicator, and a microprocessor that receives the distance from the distance detector,with the microprocessor comprising programming tocalculate an intensity of the light from the source on a target surface, with the calculated intensity on the surface used for calculating a dosage of the light on the target surface, andto compare the calculated dosage to a predetermined dosage to provide a signal to the indicator when the predetermined dosage is achieved.

Abstract
Ultraviolet light is an effective sterilization agent. Convenient mobile sterilization devices are described herein that, in certain embodiments, provide indications to a user of how much sterilizing light is required for a given sterilization goal and how much light has been applied to a surface towards that goal. Users can move the devices across a target surface as needed to sterilize or disinfect the surface, with the device tracking the dosage applied to the surface. One embodiment of a mobile device that comprises an ultraviolet C (UVC) light source, a distance detector, an indicator, and a microprocessor that receives data from the distance detector for calculating an intensity of the light from the source on a target surface and for calculating a dosage of the light on the surface to provide a signal to the indicator when a predetermined dosage is achieved.
