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

Appl.No PCT/US2021/031377 Applicant CORNELL UNVERSITY Inventor KACKER, Ashutosh
Embodiments described herein provide systems and methods for protecting doctors and others from pathogenic microorganisms aerosolized during surgical and other procedures on patients. The systems and methods generally operate by forming a partially-enclosed chamber around the patient's face during the procedure. A facial adapter and facial shield isolate a portion of the patient's face from the surrounding environment. The partially-enclosed chamber is connected to a vacuum source that brings the pathogenic particles through a filter, which further decreases the number of pathogenic particles expelled into the environment.

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.

An airborne virus protection and disinfection AIRVPD device (14) includes positive and negative electrodes (34, 36) arranged to form an electrode fluid path (35) therebetween and a high-voltage converter (38) configured to deliver power to the positive and negative electrodes (34, 36) to trigger a redox reaction. The AIRVPD device (14) also includes a chemical disinfecting unit (46) having a sponge material (47) associated with at least one of the positive and negative electrodes (34, 36) and capable of becoming impregnated with an antimicrobial capable of killing airborne viruses. The AIRVPD device (14) further includes a housing (18) encasing the positive and negative electrodes (34, 36), the high-voltage converter (38), and the chemical disinfecting unit (46). The housing (18) includes an inlet (20) and an outlet (22) in fluid communication with each other via the electrode fluid path (35). Ionized air with charged droplets external to the AIRVPD device (14) is able to flow through the AIRVPD device (14) for disinfection and neutralization.
