Patent number: 12019446Abstract: Vehicles, systems, and techniques are provided for noise reduction in detection in remote sensing systems. Noise reduction can be accomplished, in some embodiments, by narrowing a time interval to receive return EM radiation (or, in other embodiments, EM signals representative of the return EM radiation) at a system mounted in a vehicle. The time interval can be narrowed by adjusting the time during which the system can receive the return EM radiation. In other embodiments, rather than adjusting the time interval, a processing unit can remove a portion of data representative of a signal resulting from mixing probe EM radiation and return EM radiation. The data that is removed can be representative of the signal during a leading interval of the defined period during which probe EM radiation is emitted. Such a removal can result in second data representative of the signal during a terminal interval of the defined period.Type: GrantFiled: December 31, 2020Date of Patent: June 25, 2024Assignee: GM Cruise Holdings LLCInventors: Cheh-Ming Jeff Liu, Alexander Charles Standridge

Patent number: 12020720Abstract: Various technologies described herein pertain to active noise cancellation in the interior of a vehicle. In exemplary embodiments, a microphone mounted on the vehicle outputs an audio signal indicative of noise emitted by a noise source. A computing system of the vehicle determines a position of the noise source based upon sensor signals output by sensors mounted on the vehicle. The computing system further determines a position of a passenger in the vehicle based upon a sensor mounted inside the vehicle. The computing system generates a complementary signal that is configured to attenuate the noise based upon the audio signal, the position of the noise source, and the position of the passenger. The complementary signal is then output by way of a speaker in the interior of the vehicle.Type: GrantFiled: July 5, 2022Date of Patent: June 25, 2024Assignee: GM Cruise Holdings LLCInventors: Marko Tintor, Matt Fornero
