Abstract: Disinfection device against viruses, bacteria and other microorganisms using ozone without contaminating the environment with ozone or users cross contamination. Disinfection is obtained by inserting an organ (e.g. hands) into a chamber containing a predetermined ozone concentration for a predetermined time. A suction duct surrounds the chamber. Ambient air mixed with overflow ozone from the chamber is fed through the suction duct into an ozone filter, then to an air outlet so the discharged air meets FDA regulation. The top of the chamber can be permanently open for inserting hands without ozone being discharged to the environment.

Abstract: A system and a method of performing screening tests for diagnosing a developmental condition of a human subject may include: receiving one or more profile data elements pertaining to the human subject; receiving one or more first behavioral data elements that may include information that is indicative of a behavior of a human subject from one or more data sources; analyzing the one or more first behavioral data elements in view of the one or more profile data elements to obtain a suspected impediment of development of the human subject; and presenting to the human subject a personalized test, adapted to diagnose the developmental condition of the human subject in view of the suspected impediment, to perform on a UI of a computing device according to the suspected impediment.
