Patent number: 9835729Abstract: A stand-alone radio frequency (RF) hardware component comprises first and second antennas, a digitizer, a serializer, and a serial output. The first antenna receives, over-the-air, a first analog Global Navigation Satellite System (GNSS) signal in a first frequency band. The second antenna receives, over-the-air, at least a second analog GNSS signal in a second frequency band, wherein the first frequency band and the second frequency band are separate and distinct. The digitizer digitizes the first analog GNSS signal into a first digitalized GNSS signal and digitizes the second analog GNSS signal into a second digitized GNSS signal. The serializer serializes the digitized GNSS signals into a serialized output signal. The serial output communicatively couples the digitized GNSS signals, as the serialized output signal, directly from the RF hardware component to a communication device that is removably couplable with the stand-alone RF hardware component.Type: GrantFiled: June 13, 2014Date of Patent: December 5, 2017Assignee: Trimble Inc.Inventors: Gregory Craig Wallace, Peter Van Wyck Loomis, Shawn D.

Patent number: 9784829Abstract: A method and system are disclosed for tracking a remote vehicle which is driving in a lateral position relative to a host vehicle. Target data from two radar sensors are provided to an object detection fusion system. Wheels on the remote vehicle are identified as clusters of radar points with essentially the same location but substantially varying Doppler range rate values. If both wheels on the near side of the remote vehicle can be identified, a fusion calculation is performed using the wheel locations measured by both radar sensors, yielding an accurate estimate of the position, orientation and velocity of the remote vehicle. The position, orientation and velocity of the remote vehicle are used to trigger warnings or evasive maneuvers in a Lateral Collision Prevention (LCP) system. Radar sensor alignment can also be calibrated with an additional fusion calculation based on the same wheel measurement data.Type: GrantFiled: April 6, 2015Date of Patent: October 10, 2017Assignee: GM Global Technology Operations LLCInventors: Shuqing Zeng, Xiaofeng Frank Song
