Portable light fastening assembly
A portable light fastening assembly for use with the human interface of an electronic device includes a lamp housing and an adjustable attachment device extending from the lamp housing. An ultra-violet (UV) light source is at least partially enclosed in the lamp housing such that the adjustable attachment device includes an engagement member and a receptacle housing such that the engagement member can be removably fastened within the receptacle housing for holding the lamp housing in a fixed position.
1. A germicidal system for use in disinfecting a human interface device comprising:
a housing defining an aperture;
an ultra-violet (UV) light source at least partially enclosed in the housing and configured to project an illumination pattern;
an attachment device extending from the housing; and
a sensor coupled to the housing,

wherein the sensor is configured to measure movement of the attachment device relative to the human interface device and to turn the UV light source from on to off when a predetermined movement is measured.
2. The system of claim 1 , wherein the sensor is configured to measure an orientation of the attachment device and to turn the UV light source from on to off when a predetermined orientation is measured.
3. The system of claim 1 , wherein the sensor is an accelerometer.
4. The system of claim 1 , further comprising a distance sensor configured to determine a distance between the UV light source and the human interface device, wherein the system is configured to adjust an intensity and time period of the output illumination pattern based on the determined distance and a type of pathogen on the touch surface.
5. The system of claim 1 , further comprising an infrared transmitter and an infrared receiver, wherein the infrared receiver is configured to receive infrared light from the infrared transmitter and wherein if substantially all of the infrared light transmitted is not received by the infrared receiver, the system is configured to turn the UV light source from on to off.
6. A germicidal system for use in disinfecting a human interface device comprising:
a housing defining an aperture;
an ultra-violet (UV) light source at least partially enclosed in the housing and configured to project a UV illumination pattern;
an alignment light source coupled to the housing and configured to project an alignment illumination pattern at least partially overlapping the UV illumination pattern;
an attachment device extending from the housing; and
a sensor coupled to housing,
wherein the attachment device is configured to removably attach to a separate human interface device for disinfecting a touch surface of the human interface device, and wherein when the attachment device is attached to the human interface device, the alignment illumination pattern and the UV illumination pattern substantially corresponds to the touch surface,
wherein the sensor is configured to detect motion in a monitored area, wherein the monitored area is greater than the touch surface, and to turn the UV light source from on to off when motion is detected, and wherein the sensor is configured to function in conjunction with the human interface device to detect activation of the human interface device to turn the UV light source from on to off when activation is detected.
7. The system of claim 6 , wherein the alignment light source is parallel to the UV light source.
8. The system of claim 6 , wherein the alignment light source is a laser.
9. The system of claim 6 , further comprising a distance sensor configured to determine a distance between the UV light source and the human interface device, wherein the system is configured to adjust an intensity and time period of the output UV illumination pattern based on the determined distance and a type of pathogen on the touch surface.
10. The system of claim 6 , further comprising an infrared transmitter and an infrared receiver, wherein the infrared receiver is configured to receive infrared light from the infrared transmitter and wherein if substantially all of the infrared light transmitted is not received by the infrared receiver, the system is configured to turn the UV light source from on to off.
11. A self-disinfecting electronic device comprising:
a housing defining an aperture;
a human interface device at least partially enclosed in the housing and comprising a translucent material;
an ultra-violet (UV) light source enclosed by the human interface device and the housing, the UV light source configured to project a UV illumination pattern through the translucent material from an internal side of the human interface device to an external side of the human interface device;
a sensor coupled to the housing,
wherein the sensor is configured to detect motion in a monitored area, wherein the monitored area is greater than the touch surface, and to turn the UV light source from on to off when motion is detected, and wherein the sensor is configured to function in conjunction with the human interface device to detect activation of the human interface device to turn the UV light source from on to off when activation is detected.
12. The device of claim 11 , wherein the human interface device is one or more of a keyboard, display screen, and a mouse.
