Patent number: 12197582Abstract: The present disclosure relates to an implementation for a trusted computing system. According to the embodiments of the present disclosure, a master controller in an SSD, which is necessarily configured in the system, is used to provide all necessary security functionality of the system's RoT. The system does not need to contain any special RoT chip or module, does not need any modifications in the system design, is easy to adopt, and can be implemented by any system comprising a hard drive. All necessary security functions are completed by the master controller of the system's hard drive. Thus, not only can the cost of the security module be reduced, but more importantly, the mechanism directly protects information and resources (e.g., operating system, user programs, user data, etc.) that actually need to be protected in the system, and once the mechanism is enabled, the protection function cannot be bypassed.Type: GrantFiled: March 17, 2020Date of Patent: January 14, 2025Assignee: MAXIO Technology (Hangzhou) Co., Ltd.Inventors: George Fong, BingJun Chen, GuoYang Li, ChenLuan Wang, ZiHua Xiao, Hui Jiang

Publication number: 20240337733Abstract: A detection method for a LiDAR includes: obtaining detection data of K detection sweeps in a detection cycle, and changing a light-emitting scheme of a laser during the (K+1)th to Nth detection sweeps in the detection cycle based on the detection data of the K detection sweeps. The detection data includes time information and intensity information, and the detection cycle includes N detection sweeps, where N and K are integers, and 1?K<N. The FOV range for an obstacle is identified through initial detection sweeps, and at least one of the transmitting-end scheme or the receiving-end scheme are changed accordingly during subsequent detection sweeps to reduce the power consumption within a FOV range where no obstacle exists and appropriately increase the energy within the sub-fields of view and time slice range where an obstacle exists, thereby improving the signal-to-noise ratio and the ranging capability.Type: ApplicationFiled: January 12, 2024Publication date: October 10, 2024Inventors: Chenluan WANG, Xuezhou ZHU, Jin YANG, Xugang LIU, Shaoqing XIANG

Publication number: 20230152432Abstract: A lidar and a control method of the lidar, and an addressing circuit are provided. The control method of the lidar includes: acquiring an address of a starting group of detection units is paired with a group of activated emitters in the lidar, and generating a corresponding control signal for detection, where the address of the starting group of the detection units is determined based on a result of a calibration process performing a decoding process and a logic operation process on the control signal for detection, determining the address of the corresponding starting group of the detection units that has been processed by the calibration process, and determining addresses of other groups of detection units to be synchronously activated at the same time with the starting group of the detection units, determining a channel selecting address, and generating a selecting and controlling signal for corresponding channels.Type: ApplicationFiled: December 29, 2022Publication date: May 18, 2023Applicant: HESAI TECHNOLOGY CO., LTD.Inventors: Chenluan WANG, Xuezhou ZHU, Wenyi ZHU, Tingyu YAO, Shaoqing XIANG

Publication number: 20230061653Abstract: A detection circuit for adjusting a width of output pulses is provided, including: a single-photon avalanche diode configured to generate a photocurrent according to an incident photon; and a comparator, having a first input terminal to receive a signal indicating an adjustable threshold, and a second input terminal coupled to the single-photon avalanche diode to receive an electrical signal representing the photocurrent. The comparator outputs a waveform based on a comparison result between the electrical signal and the signal indicating the adjustable threshold. When a plurality of photons are received by the single-photon avalanche diode within a short time period, a pulse width of an output signal of the circuit is increased. A number of photons can be obtained according to the pulse width of the signal, and a dynamic range of the single-photon avalanche diode device is improved. A pulse width of a single-photon signal can be adjusted.Type: ApplicationFiled: October 11, 2022Publication date: March 2, 2023Inventors: Xuezhou ZHU, Chenluan WANG, Wenyi ZHU, Shaoqing XIANG
