A motion control system includes an actuator having an actuation member, the actuation member having a proximal end attached to the actuator on a first side of a joint and a distal end attached to an anchor element attachment point on a second side of the joint. A first sensor is configured to output signals defining a gait cycle and a second sensor is configured to output signals representing a tensile force in the at least one actuation member. A controller receives the output signals from the sensors and actuates the actuator, during a first portion of the gait cycle, to apply a force greater than a predetermined threshold tensile force to the anchor element attachment point via the actuation member to generate a beneficial moment about the joint and to automatically actuate the actuator.

The invention relates to the field of pneumatic actuating mechanisms and provides a diaphragm type angular travel pneumatic actuating mechanism which is ingenious in structure, good in comprehensiveness, high in matching degree, and capable of effectively fitting various specifications of angular travel valves in use so as to accurately control the opening degree and the output torque of the valves. The diaphragm type angular travel pneumatic actuating mechanism is used for driving a valve rod of a valve. The pneumatic actuating mechanism comprises an upper shell, a lower shell, a push rod driving mechanism, a push rod, an upper frame, a lower frame, a linkage mechanism, a feedback mechanism and a limit position trigger mechanism. The upper shell, the lower shell, the upper frame and the lower frame are fixedly connected in sequence from top to bottom, the upper frame comprises an upper cavity and a lower cavity which are connected into a whole, a partition plate is arranged between the upper cavity and the lower cavity, and a threaded hole is formed in the middle of the partition plate. The diaphragm type angular travel pneumatic actuating mechanism is simple in structure, low in production cost, capable of fitting in a torque characteristic curve of the valve, high in adjustment precision and good in adjustment effect.

The invention discloses toe shoes. According to the toe shoes, plastic frameworks comprising plastic top caps and plastic sole plates are arranged in the toe shoes, wherein linear openings in the left and right directions are formed on the bottom faces of the plastic sole plates, and the positions of the linear openings correspond to the parts where the toes are connected with the arches; the openings are opened at the half-tiptoe state, and the openings are closed at the full-tiptoe state. The toe shoes are suitable for being applied to industrial production, and have proper hardness and comfortable level.

The invention relates to an elasticity-adjustable gas pressure spring, which solves the technical problems of complicated structure and top-to-bottom stuffiness of a current gas spring. The elasticity-adjustable gas pressure spring comprises a spring body, and is characterized in that the spring body is formed by at least one hollow cavity column of a double-layer side wall structure, a closed cavity containing pressure gas is formed between double side walls, the cavity columns are corrugated, and at least one vent hole communicated with the cavity is arranged on each side wall. By using the corrugated structure of a accordion box and filling the pressure gas, the hardness of the elasticity-adjustable gas pressure spring is conveniently adjusted, the elasticity-adjustable gas pressure spring is particularly fine in transverse and longitudinal ventilation, a mattress comprising the elasticity-adjustable gas pressure spring is easy for removing moisture so that the influence on human health is eliminated, the elasticity-adjustable gas pressure spring is wide in one-way deformation range, meets various demands and can be adjusted in real time to enhance comfort, coiling is facilitated, transport cost is saved, and a user can use the elasticity-adjustable gas pressure spring by filling the gas and unfolding the elasticity-adjustable gas pressure spring.

The invention discloses a high-temperature-resistant flexible rubber hose outer layer rubber, which is made of the following components in parts by weight: 35 parts of rubber raw material EPDM, 65 parts of polyurethane elastomer rubber TPU, and mica powder 9 parts, carbon black 55 parts, stearic acid 2.1 parts, plasticizer 4.5 parts, accelerator DM 1.3 parts, vulcanizing agent DCP 0.8 parts, sulfur 0.76 parts, antioxidant AW 5.0 parts, composite flame retardant FR201 0.7 parts. The invention also discloses a high temperature resistant flexible rubber hose. The rubber material of the outer layer prepared by the present invention has good fluidity, can make the hardness of the hose soft and easy to coil, has a good affinity with the middle rubber layer, is not easy to crack, and has good wear resistance, which greatly improves the flexibility of the hose. scratch resistance performance.
