  • Patent number: 12631719
    Abstract: Provided is a radar detector that aids in management of unimportant sources, dynamically improving handling of such sources based upon previously-stored geographically-referenced information on such sources. The detector determines location of the detector, and compares it to locations of known sources, to improve handling of such detections. The detector may ignore detections received in an area known to contain a stationary source, or may only ignore specific frequencies or handle frequencies differently based upon historic trends of spurious police radar signals at each frequency, or based on geofenced locations. GPS is used to establish current physical coordinates. The detector maintains a list of the coordinates of known stationary source “offenders” and geofence coordinates or boundaries in nonvolatile memory. When a microwave or laser source is detected, it may compare current coordinates to geofence boundaries and/or sources in this list.

  • Patent number: 10677888
    Abstract: An enhanced radar detector in one example displays a source direction of one more detected signals simultaneously with a frequency band of the detected signal. In another embodiment, a method detects a location of a false alert source to suppress alerts emanating from the location. A geographic location of a first mid-ship point of a detected radar signal in a vehicle traveling in a first direction are identified/recorded. The geographic location of a second mid-ship point of a detected signal is also identified/recorded in a vehicle traveling in a second different direction. The recorded geographic locations/directions of travel are uploaded to a host server, or evaluated within the radar detector, to identify a false source and mark a false source at an intersection of the first and second midlines. The marked false source location can be used in a detector and/or downloaded to multiple detectors via a social network.

  • Patent number: 10197665
    Abstract: A radar detector suppresses alerts from vehicle guidance systems, by sweeping for a consistent radar signal; the center frequency of the signal is stored and the detector suppresses warnings of radar signals near that frequency. The detector uses an enhanced method for suppression of signals near a known location of a false signal source; in the event the detector detects a radar signal and finds a matching stored false signal, the detector will first compare the strength of the received signal to a threshold strength that is computed based upon the distance of the detector from the stored false signal, and will only suppress signals below threshold. The detector includes a camera directed to the road in the vicinity of the vehicle. Image data from the camera is processed to identify police vehicles as identified by flashing lights, a profile including a rooftop light bar and/or highly contrasting colored panels.
