3results about How to "Postural stability" patented technology

The limb measuring assembly comprises a standing plate, the left end and the right end of the bottom of the standing plate are each fixedly provided with an anti-skid pad, the anti-skid pads are symmetrically arranged front and back relative to the vertical central axis of the standing plate, the standing plate is arranged in an L-shaped structure state, and a first measuring plate is rotationally connected to the rear end of the standing plate; the rear end of the first measuring plate is rotatably connected with a first fixing bolt, the first fixing bolt penetrates through the first measuring plate and is fixedly connected with the standing plate, the interior of the first measuring plate is rotatably connected with a threaded rod, a rod body of the threaded rod is slidably connected with a connecting block, and the left end of the front of the first measuring plate is provided with a second measuring plate. According to the limb measurement assembly, measurement can be independently completed through standing of a measured person without assistance of other people, meanwhile, a more stable posture can be provided through standing, more accurate limb data can be obtained, and therefore autonomy and convenience of measurement are enhanced.

The invention discloses a robot layered polishing trajectory autonomous planning method for an aircraft radome component. The method comprises the steps that radome component surface multi-dimensional data are collected, and layered feature vectors are constructed; performing hierarchical clustering on the surface defects based on a weighted similarity criterion to form homogeneous defect region clusters; a self-adaptive polishing track is dynamically generated for each defect cluster, and the polishing amount is predicted in combination with an improved material removal model; the configuration and motion parameters of the robot are optimized through a lightweight solver; and constructing a hybrid spatio-temporal topological graph, scheduling global tasks by adopting a hybrid strategy, and outputting an optimal polishing track sequence of each coating layer level. According to the method, through a core mechanism of defect intelligent layered clustering, track self-adaptive generation and global collaborative scheduling, the problems of radar cover complex curved surface adaptation, random damage precise processing and multi-layer coating efficient repairing are systematically solved, and collaborative optimization of repairing precision, process efficiency and resource consumption is achieved.

The utility model discloses a body limiting structure for infant magnetic resonance, which comprises a body supporting rod, limiting supports are fixed on the outer side of the body supporting rod, the body supporting rod and the limiting supports are symmetrically arranged, the two symmetrical limiting supports are connected, a limiting concave part is arranged at the joint, a connecting rod is fixed at one end of the body supporting rod, and the other end of the body supporting rod is connected with the limiting concave part. One end of the connecting rod is connected with the body supporting rod, the other end of the connecting rod is internally and rotatably connected with the arm supporting rod in an inserted mode, a fixing structure is arranged between the body supporting rod and the arm supporting rod, arm soft cushions are fixed to the outer sides of rod bodies of the arm supporting rod, and adjustable binding bands are sewn to the surfaces of the arm soft cushions. By adding the structural design of the arms, the difficulty that an adult assists an infant in keeping a specific posture of raising the arms is reduced, the operation complexity of medical staff is reduced, and the working efficiency is improved. Due to the design of the arm cushions and the adjustable bandages, the arms of the infants can be placed more comfortably, and the discomfort of the infants in the examination process is reduced.
