Abstract: A device for blood hemostasis analysis is disclosed. A blood sample is displaced to reach a resonant state. The resonant frequency of the blood sample is determined before, during and after a hemostasis process. The changes in the resonant frequency of the blood sample are indicative of the hemostasis characteristics of the blood sample.

Abstract: A back support device has a pair of short crutches each having a shaft with an upper end and an armpit rest carried on the upper end. A pair of ball and socket connections each removably and pivotally support a lower end of each of the crutches. The lower ends of the crutches are each positioned adjacent one of a pair of pelvic bones of an individual and anchored at a fixed point either surgically or non-surgically. Each shaft extends upward from a respective one of the ball and socket connections to a respective one of the armpit rests. The lower ends of the crutches are free to rotate about the respective fixed points relative to the ball and socket connections according to movement of the individual. Unobstructed upper body movement is assured, while the vertical downward forces in the lower back vertebrae are reduced. The device may be hidden from view under a layer of clothing and permits standing, sitting, walking, running and stair climbing while keeping the hands free.

Abstract: A balancing device for a wheel and tire assembly has an elongate cylinder with an upper end, a lower end, an exterior surface and male threads formed on the exterior surface. A longitudinal cylinder bore extends axially through the cylinder and receives therethrough a suspension cord. The cord has a stop element at a support end extending beyond the lower end of the cylinder for supporting the cylinder. A support member has a wheel support flange and at least a first wheel hub centering section extending from the support flange. The centering section has a fixed diameter adapted to accommodate a particular diameter wheel hub opening of the wheel and tire assembly. An axial bore is formed through the support member and has female threads formed internally in the bore which correspond to the male threads of the cylinder.

Abstract: A new prosthetic heart valve has a standard mounting ring with a centrally located occluder and a single piece biological circular flat membrane with a central aperture adapted to be selectively closed by the occluder.The flexible membrane leans against the occluder in the closed position, and deflects axially away from the occluder when open. The occluder is held in position by spokes attached to the mounting ring, which also supports the membrane along its full periphery with one continuous readily accessible suture attachment.

Abstract: A pressure transducer incorporates a tubular body symmetrical in two transverse directions, and two pairs of diametrically opposed active strain gages secured to a single surface of the body at equally spaced locations which maintain mechanical and electrical two-fold symmetry, oriented to respond to transverse tangential bending strain in the wall of the tubular body. The four strain gages are connected in a four-legged bridge circuit, which produces a large amplitude linear output signal which is compensated for first and second order errors, without hysteresis. The transducer has a very large safety factor against rupture and may be used in line with a conduit without impeding fluid flow. It is usable for all pressure ranges down to cryogenic temperatures, and may be welded in place with no seals as part of a conduit. It is highly sensitive, with improved resolution.
