Stemming reduces inflected words to their stem or root form.
For example the words fishing, fished,fish, and fisher are reduced to the root word,fish,
so a search for fisher returns all the different variations
Returns only one member of a family of patents

A device and method for capturing and disinfecting infectants including viruses such as SARS-CoV-2 and bacteria from a gas is described. The rotational disinfectant device includes means for transmitting the infectant-containing gas to a gas inlet of a housing, which housing has a gas outlet, a disinfectant liquid inlet and a disinfectant liquid outlet; a rotor mounted for rotation in said housing and connecting to the inlets and outlets, the rotor including a plurality of disinfecting channels extending axially and parallel to a common rotation axis; and means for rotating the rotor. A disinfectant liquid collector connects to the disinfectant liquid outlet and to a return conduit that connects with the disinfectant liquid inlet. A pump transfers disinfectant liquid from the disinfectant liquid collector to the disinfectant liquid inlet through the return conduit for re-use. The return conduit, the liquid collector outlet and the disinfectant liquid inlet form a closed fluid circuit. A plurality of interconnected devices may also be used. The device and method provide an efficient means for capturing and disinfecting said infectants from a gas in order to prevent their spread.

The present invention is directed to a digital aroma system that includes diffusers that contain removable fragrance/virucide cartridges. The diffusers provide a scented air and virucide sterilization on demand into interior spaces of a vehicle or a stationary structure. When a fragrance/virucide signal is received by the diffuser, the diffuser can open the valves of the selected fragrance/virucide cartridge and/or turn on a fan to direct airflow through the selected fragrance/virucide cartridge. Dry fragrance and/or virucide particles will be distributed into interior spaces of a vehicle or a stationary structure to provide a desired fragrance or to sterilize the interior space.

 Appl.No 17665408 Applicant CEC Technologies, Inc. Inventor William R. Johnston

A system for treating air includes a first vent and second vent and an air passage in fluid communication between the first and second vents. Air is drawn into the first vent, moved through the air passage, and expelled from the second vent. The air passage includes an ultraviolet-C (“UV-C”) chamber, comprising a UV-C source, and a filter located after the UV-C chamber in the air passage and exposed to the UV-C source. Air moved through the air passage is treated by the UV-C source and then the filter. Such system may be used to treat air containing coronavirus particles.

The invention relates generally to an apparatus of sufficient dimensions such that an individual can pass through the apparatus wherein the apparatus generates sufficient hydroxyl ion content to treat and/or kill pathogens, such as protozoa, fungi, molds, viruses, bacteria, etc. on the individual or surfaces of objects passed through the apparatus. In another aspect, the invention relates generally to an apparatus that can be used in enclosed areas, such as office spaces, restaurants, bars, storage rooms, warehouses, classrooms, etc., by filtering air, passing the filtered air through a hydroxyl ion generator and distributing the hydroxyl ions into the enclosed area to reduce or eliminate pathogens.
