Soft Exosuit for Assistance with Human Motion
ActiveUS20160107309A1Beneficial reduction in metabolic consumption of energyReduce loadProgramme-controlled manipulatorChiropractic devicesControl systemHuman motion
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.

Method for manufacturing head of iron golf stick
The invention relates to a method for manufacturing the head of an iron golf stick. The method includes steps of integrally molding a head blank with a hitting surface by materials such as medium carbon steel or low carbon steel and the like, heating the center of the hitting surface of the head blank to preset quenching temperature, rapidly cooling down the head blank in a quenching manner so that hardness of the hitting surface is increased and is radially gradually reduced from the center point to the periphery of the hitting surface, forming grooves on the hitting surface, treating the surface of the head blank, and the like. Accordingly, the head of the iron golf stick is manufactured. The head of the iron golf stick has the characteristic that the hardness of a head body is low while the hardness of the hitting surface is high, abrasion resistance and a hitting function of the hitting surface are enhanced, an inclination angle is easy to be adjusted by the aid of a soft stick connection portion in the head, and furthermore, as the head is integrally molded, the hitting surface cannot be separated from the head.
