Patent number: 11997006Abstract: This application is applicable to a multi-link group addressed traffic transmission method and an apparatus. A first access point (AP) of an AP multi-link device (MLD) sends group addressed traffic indication information indicating whether each AP of other APs of the AP MLD has a group addressed traffic, so that a station (STA) can learn whether the multiple APs have a group addressed traffic. In this way, each STA of the STA MLD does not need to listen to each AP whether each AP has a group addressed traffic. This reduces power consumption of the STA MLD. This application may be applied to a wireless local area network system that supports an IEEE 802.11ax next-generation Wi-Fi EHT protocol, for example, 802.11 series protocols such as 802.11be.Type: GrantFiled: June 20, 2023Date of Patent: May 28, 2024Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Ming Gan, Dandan Liang, Yiqing Li, Yuchen Guo, Yunbo Li, Jian Yu, Xun Yang

Patent number: 8514236Abstract: In general, the present invention is directed to systems and methods for finding the gait parameters of an animal using video. The invention includes a system with a video camera coupled to a computer in which the computer is configured to automatically provide animal segmentation, foot identification, foot tracking, and gait parameter calculation. In a preferred embodiment, the present invention may use a treadmill apparatus with a transparent tread or belt for gait parameter calculation. A camera may be placed directly underneath the transparent tread such that the bottom view of the animal walking or running on the transparent tread is captured by the camera. A tilted mirror may also be placed directly underneath the transparent tread in order to reflect the bottom view images to the side where they are captured by a high-speed camera. Thus, the present invention is capable of automatically monitoring a video image to identify, track and classify the actions of various animals' feet within the image.Type: GrantFiled: September 30, 2004Date of Patent: August 20, 2013Assignee: Cleversys, Inc.Inventors: Vikrant Kobla, Yiqing Liang, Feng-Feng Wang, Yi Zhang
