Patent number: 11802961Abstract: Techniques and apparatuses are described that implement lateral-bin monitoring for radar target detection. In particular, a radar system, which is mounted to a moving platform, divides a region of interest that is associated with at least one side of the moving platform into multiple lateral bins. The radar system maps locations of detections to the lateral bins, and monitors respective quantities of consecutive frames in which detections occur within the lateral bins. The radar system determines that at least one object is present within one of the lateral bins responsive to a quantity of consecutive frames having detections within the lateral bin being equal to or greater than a threshold. By waiting for a lateral bin to have detections across multiple consecutive frames, the radar system can minimize the false-alarm rate without reducing sensitivity.Type: GrantFiled: June 28, 2022Date of Patent: October 31, 2023Assignee: Aptiv Technologies LimitedInventors: Yu Wang, Yang Wang

Patent number: 11770689Abstract: A vehicle-to-vehicle communications system utilizes passive modulation of radar signals to communicate information between vehicles. Passive radar modulators may be provided at the rear of a forward vehicle and used to enrich radar interrogation signals from a rearward vehicle with additional information. Since radar transceivers are already located on a great deal of modern vehicles, this functionality may be easily retrofitted into many vehicles without the addition of a radar transceiver. A number of vehicles in a line of vehicles may pass information back through the line by passive modulation of radar interrogation signals from each vehicle. Accordingly, a vehicle may gain information about vehicles ahead of the one directly in front of it, thereby enabling “see through radar” functionality.Type: GrantFiled: December 16, 2020Date of Patent: September 26, 2023Assignee: Qorvo US, Inc.Inventor: Richard Perkins

Patent number: 11762102Abstract: System and method for adjusting timing error in a mobile device. In the mobile device, a crystal oscillator (XO) is used by a system timer as the timing source. When the mobile device enters into a sleep mode, the system timer is set to time the duration of the sleep mode. During the sleep mode, a thermistor is used to measure and monitor the temperature changes of the XO. After the sleep mode is over, a processor in the mobile device determines the frequency changes of the XO based on the temperature changes of the XO. Based on the frequency changes of the XO, the processor determines the timing error that may have occurred when the system timer was timing the sleep mode and determines the actual duration of the sleep mode by adjusting the duration timed by the system timer based on the timing error.Type: GrantFiled: February 27, 2020Date of Patent: September 19, 2023Assignee: QUALCOMM IncorporatedInventors: Philip Crary, Troy Li, Scott Scigliano
