David E. Tupman has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • ENHANCED PHOTO-CATALYTIC CELLS
    Publication number: 20190030203
    Abstract: According to an embodiment of the present invention, an apparatus for ionizing air includes a first reflector and a first target. The first reflector receives direct UV energy (from a UV emitter) and reflects it to form reflected UV energy. The first target has an inner face that also receives direct UV energy (from the UV emitter). The first target also has an outer face that receives the reflected UV energy from the first reflector. The faces of the first target are coated with a photo-catalytic coating. The first target may also have passages between the faces.

  • ENHANCED PHOTO-CATALYTIC CELLS
    Publication number: 20180333512
    Abstract: A photo-catalytic cell may produce bactericidal molecules in air by passing air across catalyst coated targets. Ultraviolet (UV) energy may be emitted from a source. A first portion of the UV energy from the source may be applied directly onto the targets. A second portion of the UV energy from the source may be reflected onto the targets.
