Cruise passengers traveling out of Port Tampa Bay next spring could play a role in the testing of a new weapons detection system designed to improve safety in public places. Liberty Defense Holdings created HEXWAVE, which uses low-power, radar imaging and artificial intelligence to detect and identify weapons. The company has been developing the technology since 2018 and is ready to test it in 11 locations nationwide, CEO Bill Riker said. Similar to a metal detector, the system requires people to walk through portals one at a time as they are scanned. But unlike their more common counterpart, these scanners can detect both metal and non-metal items and use artificial intelligence to identify almost instantly what the item is and where it's located.
