As examined in, “The Las Vegas Resort Using Microwaves to Keep Guns Out of its Casino”, an article written by Robbie Gonzalez and published by Wired Magazine, a new technology is being tested at the Westgate Las Vegas Resort and Casino that has the ability to detect concealed firearms (Gonzalez).
According to Gonzalez, the device is the, “Patscan Cognitive Microwave Radar. Marketed by Canadian security outfit PatriotOne, the Patscan CMR combines short-range radar with machine learning algorithms to scan individual guests for guns, knives, and bombs in real time—without forcing them to line up and walk through metal detectors” (Gonzalez). Furthermore, this system is fairly small is rather concealable (Gonzalez).
Concerning the specifics of the CMR’s operation, “the first antenna emits 1,000 pulses of electromagnetic radiation per second, at frequencies between 500 MHz and 5 Ghz” (Gonzalez) while “the second antenna monitors for electromagnetic patterns inside that two-meter range. When you hit an object with electromagnetic radiation, it resonates according to its shape and material…pistols, grenades, rifles…all resonate in the frequency range that Patscan emits” (Gonzalez).
Finally, Patscan utilizes a computer and a de-facto radar signature library that can be added to in order to identify potential threats and inform local police forces (Gonzalez).
In my perspective, I view this development as a positive and ethical utilization of machine learning. Unlike facial recognition, the CMR does not necessarily care about who an individual is but rather what they are carrying. In addition, I believe that the operational procedure of this product is very “hands off” and seems to require no input or manipulation from the customer or the resort staff.
It will be interesting to follow the Patscan CMR as it progresses through its testing phase and possibly into everyday use at public hotspots such as airports, museums, or sporting events.
