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

46Filters or filtering processes specially modified for separating dispersed particles from gases or vapours
Appl.No 17103501 Applicant Iowa State University Research Foundation, Inc. Inventor James E. Fay, III

An entrainment-based filtering system for use in connection with a facemask or respirator that includes: a filter housing defining an interior volume comprising at least one airflow pathway having an airflow pathway length that is longer than the length of the interior volume and spaced within the interior volume; and a plurality of entrainment substrates. The plurality of entrainment substrates is positioned within the at least one airflow pathway and the plurality of substrates and the dimensions of the at least one airflow pathway together function to entrain particles on the surface of the chemically coated entrainment substrates and prevent at least 95% of particles traveling through the at least one airflow pathway from exiting the entrainment-based filter.

PROBLEM TO BE SOLVED: To establish a method for prevention of contracting SARS.

SOLUTION: A fabric is soaked in soap water using a surfactant for which a sterilization effect against SARS is confirmed, and the fabric is superimposed on another fabric to form a mask. The sterilization effect of the surfactant against SARS bacteria is confirmed, so that airborne infection is prevented.

Appl.No PCT/US2021/017124 Applicant KEENE, Sharon, A. Inventor KEENE, Sharon, A.
A self-sterilizing, face mask, respirator, open or enclosed face shield employs germicidal, far UV-C light safe for direct human exposure, mitigating risk of acquisition or transmission of respiratory pathogens, such as COVID 19. Device attachments or special lenses direct far UV-C light into the respiratory chamber and/or reservoir areas of infection including nasal, oropharyngeal or ocular areas to reduce or eliminate pathogens, serving also as a treatment modality. In a preferred embodiment the face shield has a removable front section, which can be exchanged or replaced with sections that include various functional attributes while maintaining germicidal protections and avoiding need to remove PPE during these activities including consumption of liquids, oral medications or food, as well as providing antimicrobial absorbent sneeze or cough guard or rhinorrhea secretion absorption, or a communication device to address communication deficiencies caused by respiratory protection barriers.

The present technology relates to respirator devices including source control features. In some embodiments, a source control mask device can include a shield (706) that substantially covers the mouth and nose of a user and a mechanism (702) that can actively extract air as it is exhaled by the user. The extracted exhaled air can then be sanitized before the mask device discharges it into the atmosphere. The mask device may selectively form a seal (720) to the user's face dependent on air flow conditions.
