  • Variable grip structure
    Patent number: 7540679
    Abstract: A variable grip structure has a shaft body formed of plural shaft portions that are rotatable relative to one another. An elastic finger-grip member encircles the shaft body and has its forward and rearward ends fixed to different shaft portions so that relative rotation of the shaft portions elastically twists the finger-grip member about the longitudinal axis of the shaft body. This construction makes it possible to adapt the shape of the finger-grip member to the hand size and shape and the preference of the user.

  • Portable electronic data collection apparatus for monitoring musculoskeletal stresses
    Patent number: 5964719
    Abstract: A portable biofeedback apparatus and method for simultaneously gathering information regarding more than one type of musculoskeletal stress. The apparatus has at least two different types of user-selectable sensors for converting different kinds of musculoskeletal activities into electrical signals. An analog-to-digital converter samples the electrical signals at predetermined rates. A memory receives and stores the digital signals. A processor centrally controls the collection, sampling, display and transmittal of the digital data. Magnitudes of the digital signals are simultaneously and in real-time graphically portrayed as a function of time.

  • Ergonomic scoop assembly
    Patent number: 5716087
    Abstract: An ergonomic scoop assembly including a scoop subassembly and scoop support subassembly. The scoop assembly is preferably detachably connectable to the scoop support subassembly. The scoop support subassembly includes a saddle member for contacting the ventral side of a user's forearm and structure for releasably securing the scoop support subassembly to the user's forearm. The scoop support subassembly further includes a rear portion to which the saddle member is attached and a fore portion attached to a handle of the scoop subassembly. When the scoop support subassembly is attached to the user's forearm the handle of the scoop subassembly defines an angle with respect to the longitudinal axis for the user's forearm of between about 115.degree. to about 125.degree..
