Publication number: 20230393246Abstract: The present disclosure provides a lidar system. The lidar system includes: an optical rotating mirror and at least two laser transceiving modules. Each laser transceiving module includes a transmitting unit and a receiving unit. The transmitting unit is configured to transmit a laser signal. The optical rotating mirror is configured to rotate around a rotating axis in a vertical direction, receive the laser signal and adjust a direction of the laser signal during rotation, and reflect the laser signal to a target object. The laser signal is diffusely reflected on the target object, which produces an echo signal. The echo signal is reflected by the optical rotating mirror and is then received by the receiving unit. The receiving unit includes a plurality of detectors arranged in an array.Type: ApplicationFiled: January 25, 2022Publication date: December 7, 2023Applicant: Tanway Technology (Beijing) Co., Ltd.Inventors: Hongpeng Li, Ruitong Zheng, Zhengjie Zhang, Shiwei Wang, Luofeng Shen, Feifei Shi

Publication number: 20110277965Abstract: The present invention provides a fin and a heat sink. The fin includes a body having at least one first through-hole and at least one first protrusion. The first protrusion extends from the first through-hole toward one side of the body to form a first protruding end. At least one first notch is provided on the body in communication with the first through-hole. The fins are stacked up to form a fin set. A first heat pipe penetrates the fin set to constitute the heat sink. The first heat pipe penetrates the first through-hole while the first notch is expanded, so that the first protruding end tightly abuts against the first heat pipe. In this way, the structural strength of the fin is improved, the first heat pipe is protected from wearing due to the rubbing of fins against the heat pipe, and the heat-conducting efficiency is increased.Type: ApplicationFiled: August 13, 2010Publication date: November 17, 2011Applicant: ASIA VITAL COMPONENTS CO., LTD.Inventors: Kuo-Sheng Lin, FeiFei Shi
