  • Patent number: 8760339
    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.

  • Patent number: 8473171
    Abstract: A vehicle has wheels, sensors for generating an input data set, and a controller. The controller is in communication with the sensors, including a first sensor for detecting an obstacle on a road surface in a first manner, and adapted to monitor a boundary of the road surface to determine when the wheels are crossing the boundary. A second sensor detects the obstacle in a second manner, and additional sensors determine inertial data of the vehicle. The controller compares the input data set to calibrated thresholds, and determines an appropriate control response such as autonomous braking based on the results. A method optimizes a collision preparation response in the vehicle by measuring the inertial data, detecting the obstacle using a radar or LiDAR device, and monitoring the boundary using an electro-optical device. A supplemental braking force is automatically applied when the vehicle crosses the boundary while the obstacle is detected.
