Abstract: A device location sensing method obtains locations of N devices in a wireless network based on channel state information (CSI). Each device in the wireless network has M antennas arranged in a non-linear manner. To determine the device locations, CSI data mutually detected between every two devices in N devices is obtained and used to calculate an angle difference of arrival (ADoA) set which includes, for every two devices in the N devices relative to each of the other devices in the N devices, an ADoA that is a difference between angles of arrival (AoAs) of the two devices relative to the other device. Relative locations of the N devices are then calculated based on the ADoA set.

Abstract: A transmission line includes an outer housing, an outer conductor, a support plate, and an inner conductor. The outer housing may include a first housing and a second housing that are fastened to each other. The first housing has a first groove, the second housing has a second groove, and the first groove and the second groove are enclosed to form a path. The outer conductor may include a first conducting layer and a second conducting layer. The first conducting layer is located on an inner wall of the first groove, and the second conducting layer is located on an inner wall of the second groove. The support plate is suspended in the path, and at least a part of an edge of the support plate is fastened between the first housing and the second housing.

Abstract: A skeleton posture determining method and apparatus, and a computer readable storage medium belong to the field of human body posture recognition, where the method includes obtaining a first skeleton posture including location information of a plurality of joints, determining a description parameter of at least one target joint of the joints, obtaining, through screening, a correct joint from the at least one target joint based on the description parameter, and performing fitting based on location information of the correct joint to obtain a second skeleton posture, where the second skeleton posture includes location information of at least one joint, and the at least one target joint is in a one-to-one correspondence with the at least one joint. Hence, the method, the apparatus, and the computer readable storage medium can improve recognition accuracy of a human body posture.
