Publication number: 20240077619Abstract: An example sensor system for use with a vehicle includes a first group of sensing devices that are associated with an essential level of autonomous operation of the vehicle. The first group of sensing devices are configured and intended for continuous use while the vehicle is being autonomously operated. The sensor system further includes a second group of sensing devices that are associated with a non-essential level of autonomous operation of the vehicle. For example, the second group of sensing devices are configured to be redundant to and/or to enhance the performance of the first group of sensing devices. The second group operates in response to certain conditions being determined during autonomous operation of the vehicle. The sensor system further includes a plurality of assemblies attached to the vehicle. Each assembly includes two or more sensing devices from the first group and/or the second group.Type: ApplicationFiled: August 25, 2023Publication date: March 7, 2024Inventors: Chiyu ZHANG, Jianqiu CAO, Pengji DUAN, Yishi LIU, Joshua Miguel RODRIGUEZ, Tristan NGUYEN, Xiaoling HAN

Patent number: 11917294Abstract: Techniques are described for compensating for movements of sensors. A method includes receiving two sets of sensor data from two sets of sensors, where a first set of sensors are located on a roof of a cab of a semi-trailer truck and a second set of sensor data are located on a hood of the semi-trailer truck. The method also receives from a height sensor a measured value indicative of a height of the rear of a rear portion of the cab of the semi-trailer truck relative to a chassis of the semi-trailer truck, determines two correction values, one for each of the two sets of sensor data, and compensates for the movement of the two sets of sensors by generating two sets of compensated sensor data. The two sets of compensated sensor data are generated by adjusting the two sets of sensor data based on the two correction values.Type: GrantFiled: May 23, 2022Date of Patent: February 27, 2024Assignee: TUSIMPLE, INC.Inventors: Alan Camyre, Todd Skinner, Juexiao Ning, Qiwei Li, Yishi Liu

Publication number: 20230331175Abstract: An integrated housing assembly mountable on a roof of a vehicle, such as a semi-trailer truck. The integrated housing assembly includes a main enclosure that includes four sides, a top panel, and a bottom panel. One of the four sides is a front panel that is inclined towards the ground. The main enclosure includes one or more cavities. A front panel of the integrated housing assembly includes one or more openings to allow cameras or sensors to be placed within the one or more cavities and behind the one or more opening. The cameras or sensors cameras can be clamped at a downward angle within multiple lock apparatus. The angled front panel and the inclined cameras or sensors within the lock apparatus allow the cameras or sensors to obtain images or sensor data from one or more regions of interest at some distance from the front of the vehicle.Type: ApplicationFiled: June 22, 2023Publication date: October 19, 2023Inventors: Qiwei LI, Todd SKINNER, Yishi LIU

Publication number: 20230243998Abstract: An absolute gravimeter and a measurement method based on vacuum optical tweezers. The micro-nano particle releasing device is equipped with micro-nano particles, and is located above laser optical tweezers, and the laser optical tweezers have two capturing beams which pass through the respective convergent lenses and then converge at an intersection. An area where the intersection is located serves as an optical trap capturing region, and the micro-nano particles are stably captured by the two capturing beams in the optical trap capturing region. The optical interferometer is electrically connected to the signal processing device, the optical interferometer measures a displacement of the micro-nano particles in real time at the beginning of a free fall process from the optical trap capturing region and sends the displacement signal to the signal processing device. The signal processing device obtains a measured value of an absolute gravitational acceleration.Type: ApplicationFiled: August 28, 2020Publication date: August 3, 2023Applicants: ZHEJIANG UNIVERSITY, ZHEJIANG LABInventors: Xingfan CHEN, Yishi LIU, Xiaowen GAO, Nan LI, Huizhu HU, Cheng LIU
