A body limb movement limiter restrains the movement of a person's arm so as to protect the person's shoulder or restrains the movement of a person's lower leg with respect to the upper leg so as to protect the person's knee. The device uses a housing having a reel disposed therein with a tether attached thereto and a shear thickening non-Newtonian fluid disposed within the housing so that the fluid acts on the reel during a payout procedure of the tether. The housing is attached to a strap secur...

An improved archery bow having innovative bow limb pockets.

A bow limb which is totally molded essentially filled with unbroken longitudinal strands of fiberglass oriented in the central configuration in parallel strands, but as approaching the exterior of the bow, the strands conform to the exterior configuration of the limb. The bow limb is also characterized by a substantially constant cross-section even though width and thickness may vary longitudinally. This maintains a constant ratio of resin to fiberglass which is important to insure uniform stren...

The compound bow has a rigid riser with a flexible limb at each end. Each limb includes a pair of parallel limb elements of substantially uniform width and a pulley is mounted between the outer ends of each pair of limb elements. The inner ends of each pair of limb elements are connected to the riser by a bridge adjustable relative to the riser. The limbs are pivoted on the riser and a cable and bow string are connected between the outer ends and reeved over the pulleys. The space or angle betwe...

A method of making a bow limb which comprises the steps of wrapping impregnated fiberglass strands around a frame to create a fiberglass and resin blank or package. The wet blank or package is then placed in the mold to be shaped and cured. The package has a calculated predetermined number of fiberglass strands, and also a calculated predetermined volume and weight of plastic resin. The mold, has two parts, a male and female. The volume of the mold may be simultaneously thinned and widened in fo...

A molded bow limb which at its remote end receives an axle assembly in a preformed axle mount at the end of the bow which includes a recess for receiving an axle cover, a pair of axle covers being provided at either end of the axle and molded with the axle in position. Thus when the axle cover assembly is mounted in the axle assembly mount at the end of the bow, precision of orientation results, no machining is required, and the force of the bow string and/or cable once in place will hold the ax...

Limb/pulley torque in a compound bow is negated by providing a restoring force, as a result of the deflected bow when drawn, comprised of unequal components which balance the torsional force imparted to the bow end by the summation of forces applied by the cable. In accordance with one embodiment, the unequal components are achieved by employing unequal cross sectional areas in the material of the respective two sides about the longitudinal axis of the bow. In another embodiment, the pulley/cam ...

The present invention relates to a system with modular components for forming a prosthetic limb, wherein the effective length of the limb is adjustable to accommodate changing needs of a particular person. Several modular components are provided, including sleeve and spacer modules. Each sleeve module has a body with a selected length and has two opposed ends that are internally threaded. Each spacer module has a body of a selected length and has two opposed ends that are externally threaded. Th...

A breathing circuit component includes an inlet, an outlet and an enclosing wall. The enclosing wall defines a gases passageway between the inlet and the outlet. At least a region of the enclosing wall is formed from a breathable material that allows the passage of water vapor without allowing the passage of liquid water or respiratory gases. The breathing circuit component may be the expiratory limb of a breathing circuit.

A prosthesis includes a knee joint having movable elements geared together and rotatable about axes located rearward of a vertical bearing axis of the prosthesis. A foot member is pivoted about a horizontal ankle joint and is urged by a first spring toward the toe-down position and by a second spring toward the toe-up position. The first spring is stronger than the second spring. A tie rod is connected from the knee joint to the first spring to reduce the force applied by the first spring so tha...
