Activists and business leaders are focusing more on technological solutions that could prevent or limit the devastation caused by mass shootings, as political solutions have thus far been nonexistent. Private companies leading the push for safety solutions include Toronto-based Patriot One Technology, which has commercialized cognitive microwave technology to detect concealed weapons from McMaster University in Canada. The system uses low-power impulse radar systems for the detection of on-body concealed weapons, identifying concealed irregular object mass based on a database of known weapon profiles. Meanwhile Austin, TX-based Athena Security utilizes artificial intelligence and computer vision through existing surveillance cameras to recognize dangerous objects and suspicious motions, including an individual holding or pulling out a gun or knife.
