Abstract: A foot supporting orthotic having parallel, separately flexing rays extending forwardly from an arch region which in use underlies the arch of a wearer's foot. The rays are bowed by spring-like elastomers and facilitate the shock absorbing and adaptation stages of walking.

Abstract: A method and apparatus for performing arcuate osteotomies wherein a wedge-shaped correction is filed rather than sawed from the bone. A combined saw and file for use in the method has a curved blade with teeth along a longitudinal edge for making an arcuate cut in the direction perpendicular to the edge, and file teeth on one or both of its curved faces for filing out the correction. The effective width of the the blade determines the tip width of the correction; the thickness of the blade determines the width of the arcuate kerf; and the radius of curvature of the blade determines the radius of the arcuate cut. Also disclosed is cutting guide for guiding a saw/file or other cutting implement to make the arcuate cut and the correction.

Abstract: A bone saw guide apparatus and method for positioning sequential saw cuts facilitates the cutting of a wedge of bone, in the correction of an angular bone deformity. An arcuate saw blade having a shaft which is parallel to its cutting edge provides greater blade strength and better control of the cut.

Abstract: A prosthetic bone or tooth implant device is disclosed which includes a generally U-shaped cap portion (69) with an upper convex surface. The implant used in bone prosthesis after an osteotomy is performed by an elongated osteotome (30) having a blade comprised of at least one curved portion (38) and at least one flange portion (42). The underside of the U-shaped cap conforms identically to the shape of the osteotome blade, so that when the device is implanted its lower surface will lay perfectly flush against the surface of the bone which has been cut. The implant is affixed to the bone by means of a pin (62) connected at one end to the underside of the implant and which is inserted at its other end into the medullary canal (55) within the bone which has been severed.

Abstract: A bone cutter comprising various curved blades and an adjustable radial arm for making arcuate cuts with the use of a reciprocating, saber or jig saw.

Abstract: A fluid filled head protector absorbs trauma with a safety valve and monitoring system.

Abstract: An electronic guidance means is utilized in conjunction with a set of guide arms, to accurately measure and display angular changes to make correction in bone surgery.

Abstract: A wedge guide of specific angular dimensions allows the excision of a precise bone wedge by the alternate use of a crescentic and planar saw in a stable and accurate manner.

Abstract: A wedge guide system of variable but precise angular dimensions that allows the excision of a precise bony wedge by the alternate use of arcuate (crescentic) and planar saws in a stable and accurate manner. Right and left sided wedges can be taken. The precise wedge can be angulated in respect to the long axis of the bone by a directional guide structure that complies with data for each surgical case enabling the surgeon to make triplanar bone corrections.

Abstract: A contact lens for the human eye have radially embedded optic fibers within the body of the lens. The fibers direct incoming light to the retina to increase the amount of stimulated retina surface available to the wearer.

Abstract: A passive platform elongates under the pressures of ambulation directing fluid wave within a bag portion. The neutral subtalar joint position is attained by adjusting elastomeric assisting straps.

Abstract: Bones are cut in parallel curvilinear cuts and are elongated or shortened or angularly adjusted with the curvilinear curse wedged together for strength. Excised parts are used to build up the cut parts. A blade or guide has a ribbon shape with opposite flanges, neck, pre-neck and loop regions. One blade or guide has additional slide blade or guides to perform double cuts.

Abstract: An orthotic apparatus to help resuppinate the foot after the initial contact phase of gait. The device consisting of a flexible envelope containing a fluid with a cambered upper surface to flex upwardly upon the generation of a fluid wave along the longitudinal axis of the foot.

Abstract: An amphibious sled has a body with a flexible frontal portion which is deformed inwardly and rearwardly to improve operational characteristics of the sled. In the water version, the flexible frontal portion is deformed downwardly, inwardly and rearwardly to act as catchers for waves and to aid in the propelling of the sled with water power. In land use, the frontal portion is deformed inwardly and upwardly.

Abstract: Shellfish are placed into a chamber which is brought rapidly to a high pressure. A lid of the chamber is magnetically sealed. The magnets are quickly released to allow the chamber pressure to blow off the cover with large springs absorbing energy. The immediate decompression causes the shellfish to open. A sonic or ultrasonic source within the chamber augments the process.

Abstract: An inverted fluid vortex is created by an impeller within an inverted funnel. Heavier than water particles are forced outward and downward by the interplay of centrifugal, centripetal, gravitational forces and the internal downward cant of a funnel. A vortical fluid apex is suctioned from the system as necessary to keep the volume of the vacuum portion of the system constant and therefore the vacuum pressure constant.

Abstract: A cutting tool (20) is disclosed which includes an integrally secured arcuate cutting blade portion (32). The arcuate blade portion is defined from a loci of a perfect circle and includes an axially elongated arcuate blade portion (38) and an axially recessed arcuate blade portion (40). The axial length of the recessed portion is equal to that of an adjacent planar blade portion (42). This configuration permits the elongated arcuate blade portion to be retained within a first distinct cut of the material to be worked on or bone being cut while the entire tool is rotated to a distinct second position along the upper surface of the material in order to perform a distinct second cut. These two distinct cuts serve to form a removable section (58) of the material being worked upon or bone cut, and in this manner adjacent sections of the material can be repositioned relative to one another once the second cut is performed and the section is removed.

Abstract: Solar heat collectors resembling stamen of a flower consisting of a bulbous portion and stem collect heat energy. Lens systems, black bodies and focusing mirrors can be used in conjunction with the above mentioned stamen. The stamen are in clusters with each clusters' stems leading into a central core. A more elaborate version connects a plurality of central cores to a master core for heat transfer or utilization.The stems of the stamen are flexible to allow for customized installation and deployment. The lengths of stems can be varied for optimum solar contact of their bulbous portions.The stamen apparatus can be colorfully tinted to enhance the devices esthetics.
