  • Dynamic display and control of UV source for sanitization in mobile devices
    Patent number: 8330121
    Abstract: A mobile sanitizer movable across a surface to sanitize the surface. The sanitizer may comprise an ultraviolet light source that illuminates the surface and a microprocessor control. The control may adjust the light source intensity in response to a speed of the movement of the light source relative to the surface. And, for instance, the control may drive a display indicating how movement of the device relates to sanitization settings input by a user.
