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. Notification varies depending on the stored information and current operating modes.

Claims (28)

1 . A radar detector device comprising:

a receiver device configured to detect a plurality of signals generated in a context of law enforcement activity across a plurality of different frequency ranges; and

a processor, wherein the processor is configured to:

detect a position of the radar detector device;

determine that the radar detector device is located in a geofenced area;

suppress alarms for signals in a first frequency band within the geofenced area; and

detect signals in a second frequency band within the geofenced area,

wherein alarm suppression does not require historic data of the radar detector device.

2 . The radar detector device of claim 1 , wherein the radar detector device has received no input inside the geofenced area on the first frequency band.

3 . The radar detector device of claim 1 , wherein the radar detector device has not met a threshold of incident inside the geofenced area on the first frequency band.

4 . The radar detector device of claim 1 , wherein the alarms for the first frequency band are suppressed based only on the device being within the geofenced area, independent of specific position within the geofenced area.

5 . The radar detector device of claim 1 , wherein the alarms for the first frequency band are suppressed at all positions within the geofenced area.

6 . The radar detector device of claim 5 , wherein the geofenced area is greater than 1 square mile.

7 . The radar detector device of claim 1 , wherein location accuracy of the radar detector device is within 3 meters.

8 . The radar detector device of claim 1 , wherein the geofenced area includes a plurality of cells, wherein each cell has a standard and uniform shape and size.

9 . The radar detector device of claim 8 , wherein each cell respectively corresponds to a set of geographic coordinates.

10 . The radar detector device of claim 9 , wherein the geofenced area has a different shape than each of the cells.

11 . The radar detector device of claim 1 , wherein the geofenced area is larger than a maximum effective range of the radar detection device.

12 . The radar detector device of claim 1 , wherein a first size of the geofenced area is at least an order of magnitude larger than a second size of an area of a location based lockout.

13 . The radar detector device of claim 1 , wherein a first size of the geofenced area is at least two orders of magnitude larger than a second size of an area of a location based lockout.

14 . The radar detector device of claim 1 , wherein a size of an area of a location based lockout is ⅛ square miles or less, and the geofenced area is greater than 1 square mile.

15 . The radar detector device of claim 1 , wherein the first frequency band is one of a segment of X band, a segment of K band, a segment of Ka band, or a segment of laser band.

16 . The radar detector device of claim 1 , wherein the processor is further configured to omit processing associated with the first frequency band within the geofenced area.

17 . The radar detector device of claim 16 , wherein the omitted processing includes storing a current cell and the first frequency in memory.

18 . The radar detector device of claim 16 , wherein the omitted processing includes comparing stored data to a threshold.

19 . The radar detector device of claim 16 , wherein the omitted processing includes transmitting data to a database system for processing.

20 . The radar detector device of claim 16 , wherein the omitted processing includes checking a list of coordinates or a list of cells.

21 . The radar detector device of claim 16 , wherein the omitted processing includes determining whether audible or visual alarms are suppressed based on a previously input user instruction.
