Wireless connectivity in a radar detector

摘要

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.

主权项

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, and a first wireless device interface comprising a radio compliant with a wireless personal area network communication protocol, the processor interacting wirelessly with an external device via said first wireless device interface and connecting to a cellular device providing an Internet connection, the cellular device exchanging data with a remote server via said Internet connection, wherein the external device comprises a global positioning receiver, a display, and a second wireless device interface connectable to the first wireless device interface, the display generating alerts of radar when detected by the radar detector, and presenting a map representing the geographic location of the external device.
