Abstract: The knee joint weight-bearing apparatus includes a buttock attaching part, a lower-leg attaching part, and two thigh connection units. Each thigh connection unit includes a front thigh link and a rear thigh link. The buttock attaching part, the lower-leg attaching part, the front thigh link, and the rear thigh link constitute a four-bar linkage. The buttock attaching part is configured so that when a user applies his/her weight to the buttock attaching part, a tensile force is generated in the front thigh link and a compressive force acts on the rear thigh link. The rear thigh link includes a gas spring that is configured to be stretchable in a longitudinal direction thereof and generates a resistive force against the compressive force.

Abstract: A knee joint weight-bearing apparatus, which is used as a leg brace, includes an inner thigh link, an inner lower-leg link, inner extension force generation means for generating an inner extension force between the inner thigh link and the inner lower-leg link in a direction in which a knee joint of a leg extends, an outer thigh link, an outer lower-leg link, and outer extension force generation means for generating an outer extension force between the outer thigh link and the outer lower-leg link in a direction in which the knee joint of the leg extends. The inner extension force is stronger than or weaker than the outer extension force.

Abstract: A walking training apparatus according to related art has a problem that a state of walking training undergone outside a medical service provider cannot be acquired. An equipment data providing system according to the present disclosure includes a database configured to manage sensor data measured by a sensor of equipment from a wearer for walking training, adjustment information indicating an adjustment state of the equipment, and the equipment or the wearer in association with each other, and a transmission information management unit configured to transmit information managed in the database in response to an inquiry request from outside to an inquirer who makes the inquiry request.

Abstract: A transfer assist apparatus includes: an arm portion that has a first joint and a second joint; a holder portion linked to the arm portion; a manipulation handle for manipulating the position and the posture of the holder portion; a first drive mechanism that drives the first joint; a second drive mechanism that drives the second joint; and a control portion that controls the first drive mechanism and the second drive mechanism so that the posture of the holder portion is maintained in a predetermined acceptable range, based on information that is input from the manipulation handle, and angle information regarding the first joint and the second joint.

Abstract: Since both a driving means for lifting a work and a driving means for turning operation must have been arranged in a conventional work transfer apparatus, the apparatus has been large in size and heavy in weight. A work transfer apparatus is provided with a holding tool for holding a window, i.e., the work, and a supporting arm for movably supporting the holding tool. The window held by the holding tool is transferred by a supporting arm to window frames to which the window is to be assembled, and the posture of the window is changed to that corresponds to the window frames. Furthermore, the supporting arm is configured to be a closed loop link mechanism wherein a plurality of links are connected to form a closed loop. The posture of the holding tool one link of a pair of links connected to the holding tool of the supporting arm can be fixed.

Abstract: Provided are a power assist apparatus and its control method, which realize improvements in positioning precision and in workability while reducing the burden of a work positioning operation on a operator by burdening a portion of the positioning work on the power assist apparatus and while making good use of the decision or experience (or institution or knack) by the operator when the operator positions the work by using the power assist apparatus. The power assist apparatus thus autonomously cooperated with the working action of the operator comprises a transfer tool including an articulated robot, a sucking jig and a free joint for gripping and transferring windows, and a control device for controlling the actions of the transfer tool. The control device divides and stores a series of working tasks into a plurality of working section, and sets control logics for the individual working sections and for the individual working directions, in which the power assist apparatus has degrees of freedom.

Abstract: A fluid-filled elastic hollow body 2, includes a pressure sensor 4 for detecting the pressure of the fluid in the elastic hollow body, and an adapter 6 for coupling the elastic hollow body to an external movable member. The elastic hollow body 2, having a hollow sphere portion 2a having a roughly constant wall thickness, is deformed when an external contact load is applied causing a rise in its inner pressure detected by the pressure sensor 4. The invention provides: (1) that the sensor can accurately measure a contact load without being influenced by a change in direction of force measured; (2) that it can be attached easily and measure a load immediately after attachment; (3) that it is resistant against instantaneous shock load; (4) that it can easily model a substance when it comes in contact therewith; and (5) that its sensitivity does not deteriorate.

Abstract: The present invention includes an elastic hollow body 2 in which a fluid is filled tightly, a pressure sensor 4 for detecting the pressure of the fluid in the elastic hollow body, and an adapter 6 for coupling the elastic hollow body to an external movable member. The elastic hollow body 2, having a hollow sphere portion 2a having a roughly constant wall thickness, is deformed when an external contact load is applied thereon, to cause a rise in its inner pressure, which is in turn detected by the pressure sensor 4.
