WIRELESS CONNECTIVITY IN A RADAR DETECTOR
First Claim
1. A police activity detector, comprising:
- a receiver for detecting electromagnetic signals generated in the context of police activity, a processor coupled to said receiver and evaluating electromagnetic signals received by said receiver to determine whether a warning is to be issued, the processor operating under control of software and/or data, andan external memory interface coupled to said processor, the processor connecting to external memory connected to said external memory interface to retrieve or store said software and/or data or copies thereof.

Abstract
Wireless and other external connectivity technology is used in various ways to enhance or improve upon existing radar detector and police activity detection systems. External memory interfaces, such as SD cards or USB, provide external storage. Wireless interfaces such as Bluetooth, Zigbee, 802.11, and wireless personal area network communication protocols, allow a detector processor to interact wirelessly with external devices, such as a Bluetooth headset, a cellular network device providing a server connection, or toggle buttons used to indicate the presence of police activity at a current position. Further, radar detectors are upgraded to provide GPS capabilities, using the existing power/data connector of the radar detector.

21. A position-responsive police activity detector upgrade device, for use with a radar detector having a power and data connection, the radar detector receiving electroical power and communicating data over the connector including at least an indication of an alert generated upon detection of police radar, and the radar detector responding to data received over the connector including at least a muting signal for muting of an alert, the upgrade device comprising
a housing that incorporates a cigarette lighter plug for obtaining 12 volt power from a cigarette lighter connector, a power and data connection for connection to a radar detector power and data connection, a position indicating circuit for detecting a current position of the upgrade device, storage identifying locations at which alerts otherwise generated by a radar detector are to be muted, the upgrade device including circuitry coupling power obtained from said cigarette lighter connector to a connected radar detector, receiving an indication of an alert from a connected radar detector, and providing a muting signal to a radar detector in the event a location identified by said position indicating circuit correlates to a location at which an alert is to be muted.
