This invention relates to various methods and designs for a built M
. - - _ apparatus for biocidal purposes.
It is the object of the invention to provide added protection from bacteria and viruses in public places such as in Hospitals and Airports etc. In some cases the applications may be practical for home or commercial use as well. In this invention, the UV-C
emitting devices are housed within the apparatus.
Field of use The intended applications are for apparatus such as, but not limited to, toilet seats(fig. l), door handles as well as push plates for doors and handles (fig.2) for shopping carts (fig.3), essentially objects that many people touch during the course of the day and where bacteria and viruses can be passed on to others.
The exposure of germicidal ultraviolet is the product of time and intensity.
High intensities for a short period and low intensities for a long period are fundamentally equal in lethal action on bacteria. The inverse square law applies to germicidal ultraviolet: The killing power decreases as the distance from the lamps increases.
In some embodiments of this invention, it is desirable to use more intense frequencies for a shorter period of time in order to limit exposure to the UV-C waves and to accomplish the desired functions quickly. Some of the effects of UV-C exposure are minor skin irritation and minor eye irritation, none of the effects of brief WC exposure are permanent and will be avoided by employing devices such as time delays, motion sensors, micro switches or mercury switches as necessary.
The UV-C bands are created for this invention using fiber optics, gas filled tubes or prisms. "Cold Cathode" type lamps are a consideration because the lamps have a very long life unaffected by frequency of starting.
Research has demonstrated that within the UV-C band the most efficient frequency for microbial destruction is between 254nm and 265nm.Therefore the desire is to create the UV-C light within this range.
Another method that may be employed at a later date would be to use microwave induced resonance to achieve the desired biocidal effects. The first three harmonic modes of DNA
have been shown to be excitable in the range of 2.5 - 20 Ghz by Davis et al.
The area of research is fairly new, however and at this time the specific frequencies and power levels needed to dissociate nucleic acids are unknown and therefore would require further research. Microwave induced resonance is sometimes employed to destroy bacteria and viruses, but at present time requires prolonged exposure and is not practical for our intended uses.

outlined above. Prism, gas filled tubes or fiber optics.
The light is then made to fit the desired application. This can be accomplished by using flexible tubing or plastic housings for the specific application.
The apparatus itself will be made of a plastic that will allow the UV-C bands to penetrate.
Time delays, motion sensors, micro switches or mercury switches will be used as necessary to control the UV-C light. Deflectors can also be used where practical.
For example,(fig.2) if using on a door handle, a motion detector could be employed to make the unit turn off as soon as movement is picked up by the sensor, making sure that people will not come in close contact with the UV-C light while it is in operation. The unit will also be programmed to switch on for a desirable length of time and then switch off again, once the destruction of the bacteria/viruses is accomplished.
The device is the connected to the appropriate power supply and is ready for use.
