Computer input device sterilization method and apparatus
First Claim
1. A computer input device sterilizer comprising:
- a box open on one side and dimensioned to fit over and entirely cover a computer input device disposed on a surface;
a switch biased to the off position and connected to the box so that the switch is actuated to the on position when the box is placed on the surface so as to cover the computer input device;
a power supply connected to the switch;
a UV light source attached to the inside of the box; and
a timer/power circuit for providing a timed application of power from the power supply to the UV light source when the switch is actuated to the on position;
wherein sterilization of the computer input device is effected when the box is place over the computer input device resting on the surface, causing the UV light source to emit ultraviolet radiation below 200 nm and create ozone gas.

Abstract
A computer input device sterilization apparatus having ultraviolet sterilization in an enclosed container to kill bacteria and other disease carrying organisms. The invention comprises a horizontal or vertical container dimensioned to fit over computer input devices such as keyboards, mice, trackballs, touchpads and the like. An ultraviolet source within the container irradiates the computer input device with UV light which, in one embodiment generates ozone gas, thereby killing any microorganisms that might reside on the computer input devices. Ultraviolet radiation below 200 nm can also be used thereby creating ozone gas having germicidal characteristics. The ozone gas is circulated in and around the input device thereby providing further sterilization together with the ultraviolet radiation. A sterilization switch turns the UV source off when the container is opened. A timer/power circuit provides the times application of power to the UV lamps to provide UV illumination consistent with the substantial sterilization of the input device in question.

7. A method for sterilizing a computer input device comprising:
-
enclosing the computer input device in a box that is open on one side and is dimensioned to fit over the computer input device resting on a surface, the box comprising;
a UV light source that emits UV light below 200 nm and is attached to the inside of the box;
a timer/power circuit for providing a timed application of power connected to the UV light source;
a sterilizer switch biased to the “
off”
position connected to the timer/power circuit; and
a power supply connected to the sterilizer switch;
generating UV light when the box is placed over the computer input device resting on the surface, thereby actuating the sterilizer switch, applying power to the timer/power circuit, thereby applying power to the UV light source, thereby producing UV light thereby killing bacteria and pathogens that may be present on the computer input device; and
producing ozone gas thereby killing bacteria and pathogens that may be present on the computer input device. - View Dependent Claims (8)
