  • Patent number: 6155960
    Abstract: A training dummy in human form that mimics realistic human movements and reactions to forces extended onto the dummy by a user, and including a torso having at least one upper arm attachment point with an XY & Z axis, at least one upper arm fastened to the torso at the at least one upper arm attachment point and capable of rotating about the X axis and pivoting about the XY & Z axis of the upper arm attachment point. A returning means securely attached to the dummy for returning the upper arm and torso back to their initial positions after having a twisting, restraining, or striking force exerted upon the dummy. A counterbalancing means attached to the torso for counterbalancing a force applied to the dummy. The dummy is suspended from the counterbalancing means which tends to return the dummy to an upright position if the dummy is taken down to the floor.

  • Patent number: 4102210
    Abstract: A transducer responsive to pressure or force, comprises a diaphragm secured around its periphery to the housing of the transducer and having a cup-shaped portion formed concentrically therein. Means are provided for applying, in use, a pressure or force to one surface of the diaphagm and means responsive to the resulting deflection of said diaphragm for providing an indication of the applied pressure or force. Strain gauges are mounted on an annular portion of the diaphragm which extends between the cup-shaped portion and the periphery of the diaphragm. An overload protection device may be provided to limit deflection of the diaphragm.

  • Patent number: 4091472
    Abstract: The foot comprises a keel of hard material such as wood and having a flat attachment surface, a curved instep portion and a planar diminished heel portion. Recesses are formed above and below the front ends of the toe portion and a resilient reinforcing tongue portion is secured within each recess. These tongues extend forwardly of the keel and are connected together with a relatively dense foamed plastic therebetween so that the resistance of the tongues and of the plastic controls the flexural resistance of the toe portion. The shape of the heel portion permits the maximum amount of foam possible to be provided at the heel so that the density of the heel is variable and controllable by the foaming process. The final foam process envelopes the keel with the exception of part of the flat top, in one-piece moulded rubber or synthetic plastic foam so processed as to produce a skin on the exterior surface.
