The invention relates to a sitting body forward bending action standard detection method, and belongs to the technical field of action standard detection, and the method comprises the steps: detecting left and right ankle coordinates, left and right knee coordinates, left and right hipbone coordinates, left and right shoulder coordinates, left and right elbow coordinates, left and right wrist coordinates, and hand tip coordinates of left and right hands of a person; when the 14 coordinates are detected, judging that the personnel has made preparation work, and starting to detect the forward bending action standard of the sitting body; 14 coordinates of each frame are recorded in the detection process; determining a completion score of each frame according to the hand tip coordinates of the left and right hands; judging whether the person completes the action according to the completion score of each frame, and obtaining a valid score or an invalid score; determining an upper limb termination score and a lower limb termination score of each frame, and determining a termination score of each frame according to the upper limb termination score and the lower limb termination score of each frame; and judging whether the action is illegal or not according to the termination score of each frame, and if the judgment result is that the action is illegal, terminating the assessment, and judging that the score is invalid.

The application discloses a method and system for body positioning in a face-to-face confrontation XR game, and relates to the technical field of spatial positioning in a confrontation XR game. In the face-to-face confrontation XR game, the glasses camera of an opponent player is used as an outward-inward sensor, and the world coordinates of key points such as the glasses center, left and right wrist, and left and right ankle of each player are calculated through triangulation in cooperation with the outward-inward 6DoF positioning of each pair of glasses. In the game, precise body positioning can be realized without wearing any additional sensors at the positions of the wrist, ankle and the like.

A system and method fare provided for preparing the distal tibia in an ankle replacement via an extra-medullary jig. An extra-medullary jig or C-bracket is positioned on the tibia with a registration reference and positioned with respect to a resection in the distal tibia via an anterior mounting block which is independent of the surface of the tibia. The mounting block allows the adjustment of the stem cartridge with respect to the registration reference such that the stem cartridge is properly aligned within the resection. The C-bracket is further attached to the tibia via an adjustable proximal alignment arm which attaches to a pin embedded in the proximal tibia. The C-bracket aligns the tibia, foot and ankle and the trajectory of the reamer, and is universal with respect to the left and right ankle.

The utility model discloses a lower limb massager which comprises a foot frame and a foot massage device installed on the foot frame. The foot massage device comprises a left foot support which is arranged to be capable of turning up and down relative to the foot support so as to stretch the left ankle of a user; the right foot support is arranged to be capable of turning over up and down relative to the foot frame so as to stretch the right ankle of the user; the overturning driving mechanism is used for driving the left foot support and the right foot support to overturn up and down; the turnover driving mechanism comprises a motor, a left transmission assembly located between the motor and the left foot support, and a right transmission assembly located between the motor and the right foot support. According to the lower limb massager, the left foot support and the right foot support can be turned over up and down relative to the foot frame, and the design thought of the lower limb massager is enriched according to the technical scheme. The utility model further provides a massage chair.

The utility model relates to the technical field of ankle joint fixing braces, in particular to an ankle joint fixing brace which comprises an outer plastic supporting frame, a front baffle, an inner liner, a plastic plate, a belt buckle, an all-nylon hook-and-loop fastener bandage, an inflation device, an air delivery pipe, an air bag, a shoe sole and an insole. According to the utility model, the outer plastic support frame is designed according to the curvature of the shank and the ankle of a human body, so that the brace can be worn more closely to the body shape of the human body, the inner liner adopts a magic tape to adapt to the fixation of different leg circumferences, the front part of the shank and the instep are provided with a plastic plate for front pressurizing support fixation, and the front baffle is arranged in front of toes, so that the brace is more compact to wear; meanwhile, the all-nylon hook-and-loop fastener bandages are adopted to pressurize and fix the plastic plates, wearing is convenient, the air bags arranged on the two sides of the interior of the outer plastic supporting frame can pressurize and support the ankles, and the problem that the empty volumes are different after the left ankle and the right ankle are worn can be solved.

An anti-glare method for a medical scanning bed and a computer program product thereof are disclosed, the method comprising: identifying a plurality of articulation points of a patient associated with implantation using an identification model, where the articulation points comprise articulation points of a face, hip, or lower limbs, where the face comprises eyes, mouth, or nose; the hip comprises a left hip and a right hip; the lower limbs comprise a left knee, a left ankle, a right knee and a right ankle; obtaining the confidence coefficient of each joint point; comparing each confidence coefficient with a preset confidence coefficient threshold value; and when the comparison accords with the preset condition, controlling the intensity of the light projected above the scanning bed. Through intelligent state recognition and automatic adjustment, the glare problem in the medical scanning process is effectively prevented, and the comfort level and the medical examination efficiency are improved.

A humanoid robot includes an upper region, a lower region, and a central region. The upper region includes a head, a torso, and a pair of arms coupled to the torso. The lower region is spaced apart from the upper region and includes a pair of legs. The lower region of the robot includes left and right ankle assemblies configured to control a pitch movement and a roll movement of left and right feet of the humanoid robot. Each ankle assembly can include a foot-roll actuator assembly and a foot-roll actuator assembly. The foot-roll actuator assembly is coupled to the foot and to the foot-flexion actuator. The foot-roll actuator assembly is configured to control roll movement of each respective foot relative to both a shin of each leg and the foot-flexion actuator assembly.
