Quote : " When authorities searched the hotel room of Mandalay Bay gunman Stephen Paddock earlier this year, they found 23 firearms. For Vegas resorts and casinos, screening for concealed weapons has become more critical than ever, but most would prefer to do it without metal detectors, wands, pat-downs, and other buzzkill tactics.
That's where Patscan comes in. Each radar unit consists of a service box and two antennae ( the combined footprint is about the size of a movie poster ). The first antenna emits 1,000 pulses of electromagnetic radiation per second, at frequencies between 500 MHz and 5 Ghz. Yes, that frequency range makes these microwaves, and no, they're not going to cook anybody; to keep them from interfering with cell phones and GPS devices, Patscans generate a very weak signal. That also limits their detection range to about two meters. "
Quote : " PatriotOne maintains a growing database of known radar signatures, which Patscan's onboard computer uses to distinguish weapons from benign objects and notify security personnel. " The best analogy is antivirus software, " says PatriotOne CEO Martin Cronin. " You get it out of the box and it's equipped with a set of signatures. But it’s constantly checking the database for new ones. " Cronin says that, in time, machine learning algorithms will also allow Patscan devices like the ones at Westgate to improve with use, by learning to separate the normal signatures of their immediate environments from abnormal ones.
