The invention comprises a solid state infrared source and method of use thereof comprising: (1) an electrically conductive film, comprising a semi-transparent material, the semi-transparent material comprising a transmission property of at least forty percent, wherein at least forty percent of internal infrared emissions from the electrically conductive film transmit to an outer surface of the electrically conductive film, wherein the infrared emissions comprise a peak intensity between 3.9 and 6 micrometers; (2) a first silicon nitride layer; and (3) a second silicon nitride layer, the electrically conductive film positioned between the first silicon nitride layer and the second silicon nitride layer, where applying an electric current of less than one Watt through the electrically conductive film raises a temperature of the electrically conductive film to in excess of eight hundred degrees centigrade in less than twenty milliseconds resultant in the infrared emissions.

Electrically conductive-semitransparent solid state infrared emitter apparatus and method of use thereof

The invention comprises a solid state infrared source apparatus and method of use thereof, comprising: (1) an electrically conductive film comprising: an emission side and a back side opposite the emission side and a surface area to height ratio of at least five hundred to one; (2) a first dielectric film contacting the back side of the electrically conductive film; and (3) a reflective layer, the reflective layer embedded in the solid state source between the first dielectric film and a support layer, wherein the electrically conductive film emits infrared light upon warming with an electrical current during use, the infrared light sequentially reflecting off of the reflective layer, transmitting through the electrically conductive film, and emitting from the solid state source. Preferably the electrically conductive film comprises zinc oxide and the reflective layer is deposited into a basin in a second dielectric film.

The invention comprises an infrared source and method of use thereof comprising the steps of: (1) providing a solid state source, comprising: a film of oxide particles comprising an average particle size of less than ten micrometers, gaps between the oxide particles comprising an average gap width of less than ten micrometers, and a heating element embedded in the solid state source; (2) applying a pulsed current to the heating element to heat the heating element; and (3) heating the film of oxide particles to at least seven hundred degrees using thermal conduction from the heating element resultant in the film of oxide particles emitting infrared light in a range of 1.1 to 20 micrometers, where the infrared source operates continuously with heating and cooling of the oxide particles through a differential of at least 200&#xb0; C. occurs at least five and less than thirty times per second.

Solid state particulate metal oxide infrared emitter apparatus and method of use thereof

The invention comprises an infrared source and method of use thereof comprising the steps of: (1) providing a solid state source comprising: an electrically conductive zinc oxide film having a thickness of less than five micrometers and a film of metal oxide particles, the metal oxide particles comprising a mean diameter of less than ten micrometers; (2) passing an alternating, pulsed current through the zinc oxide film, the pulsed current heating the zinc oxide film to greater than 700&#xb0; C. in less than twenty milliseconds using less than one Watt, which results in a first infrared emission from the zinc oxide film; and (3) heating the film of metal oxide particles, using thermal conduction from the zinc oxide film, to at least 700&#xb0; C., resultant in a second infrared emission from the film of oxide particles, where the first and second infrared emissions exit the source through an emission side.

Dual emission layer solid state infrared emitter apparatus and method of use thereof

Water and solid debris are separated from gasoline during its storage within a container. The separation is effected automatically, at low cost and in a highly reliable manner. It is continuous throughout storage and is not reversed by portage of the container or removal of gasoline therefrom. Engines fueled with gasoline from the container are far less subject to contamination from water or impurities than those fueled from gas cans of the conventional type.
