Radar detector with position and velocity sensitive functions
First Claim
1. A police activity detector comprising:
- a receiver section receiving signals generated in the context of law enforcement activity, anda warning section responding to the receiver section and providing a warning if a received signal correlates to a signal generated in the context of law enforcement;
the detector being responsive to a position determining circuit,the detector including a controller and memory, the controller selectively operating a warning lockout mode in which the controller will store in said memory the position at which said warning lockout mode was engaged and information relating to signals received by said receiver section at that location, the detector controller responding, under predetermined conditions, to signals initially received after engagement of said warning lockout mode, by storing the position at which said later received signals are received or information relating to said later received signals, or both.

Abstract
A GPS enabled radar detector dynamically handles radar sources based upon previously stored geographically referenced information on such sources and data from the GPS receiver. The detector includes technology for determining the location of the detector, and comparing this location to the locations of known stationary sources, to improve the 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 may handle frequencies differently based upon historic trends of spurious police radar signals at each frequency. Notification of the driver will take on a variety of forms depending on the stored information, current operating modes, and vehicle speed.

13. A police activity detector comprising:
-
a receiver section receiving signals generated in the context of law enforcement activity, and a warning section responding to the receiver section and providing a warning if a received signal correlates to a signal generated in the context of law enforcement; a memory, and a position determining circuit, the warning section being responsive to a stored position in said memory and to said position determining circuit, to provide information regarding said stored position, including a directional indication of the relative direction to said stored position compared to the current location or direction of motion of said detector. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
