Beltronics' patented AutoScan feature continuously analyzes all incoming signals and automatically rejects unwanted false alarms.Could this: [replacer_a] be the Belscort Autoscan / AutoSensitivity Patent?Passport 8500 X50's patented AutoSensitivity™ mode intelligently distinguishes real threats from other known sources of radar - virtually eliminating false alarms.
I saw that the RX65's and X50's Autoscan/Autosensitivity modes are patented, so I looked on my RX65 box and all the patents were there. There are only a few within the last 5 years, and I think this might be it. Finally we see what it actually does. 8)
A police radar detector detects police radar signals in the X, K and wide Ka police radar bands and rejects interfering Ka band signals that are a higher harmonic of a nuisance source having a fundamental frequency adjacent to the X police radar bands. Each of the three police radar bands is separately swept in a first mixer stage with the resulting IF signal concurrently demodulated in two IF circuits. The first IF circuit detects signals that were received in the X, K and outer portions of the wide Ka band during respective sweeps. The second IF circuit detects nuisance signals adjacent to the X and K bands, and the inner portion of the wide Ka band during respective sweeps.
