An axial rotary energy device including a segmented stator assembly having a plurality of segments arranged in an annular array. Each stator segment is constructed by stacking a plurality of PCB power conductor layers and a plurality of PCB series layers. Each layer having radial conductors extending from an inner via to an outer via. The vias electrically connect selected radial conductors of the series conductor layer and power conductor layer. Each power conductor layer includes a pair of positive and negative terminal vias for one phase of the electric current connected to selected outer vias. A daughter PCB layer electrically connects two adjacent segments together by having a first portion electrically connected to a negative terminal via located in one segment and a second portion electrically connected to a positive terminal via located in an adjacent segment together with a current conductor electrically connecting the two terminal vias together.

A screw holding and driving device for use with powered drills including a slidable transparent sleeve mounted in concentric relation with a screw drive shaft of the device. The sleeve is provided with an internal surface that is fluted with the fluted surfaces extending parallel to the longitudinal axis of the cylindrically shaped sleeve. The inner surfaces with larger radii remain clear of the shaft and thus will not be scratched as the shaft moves relative to the sleeve. Further, a split ring of oval construction is provided for holding the sleeve on the shaft. The ends of the split oval retaining ring are sized to fit in a groove on the shaft and thus do not extend outside the groove to scratch the transparent sleeve.

In one embodiment, an apparatus includes a first member that supports a magnetic flux carrying member and a second member that supports a magnetic flux generating member disposed for movement relative to the first member. An air gap control system is coupled to at least one of the first member or the second member and includes an air gap control device that is separate from a primary magnetic flux circuit formed between the first member and the second member. The air gap control device is configured to exert a force on one of the first and second members in response to movement of the other of the first and second members in a direction that reduces a distance between the first and second members to maintain a minimum distance between the first and second members and/or substantially center the one of the first and second members within the other.

The present invention provides an axial rotary energy device which is arranged in a multi-phase electric current configuration. The device includes a rotor having a plurality of permanent magnet poles secured thereto and further includes a stator formed by stacking a plurality of printed circuit board working conductor layers together with a plurality of printed circuit board connecting layers. The stator having at least one working conductor layer for each phase of the electric current and at least one connecting conductor layer associated with one working conducting layer. The working conductor layer and the connecting conductor layer each having radial conductors extending from an inner diameter through-hole to an outer diameter through-hole. A plurality of via conductors are provided for electrically connecting selected ones of the radial connectors of the connecting conductor layer to selected ones of the radial connectors of the working conductor layers through the through-holes.

An improved two-ended reversible drill/driver tool for use with power drills. The tool having a hollow cylindrical socket that at one end has a drive shank for insertion into a chuck of a powered drill, and, at the opposite end, has a polygonally shaped opening therein for receiving a correspondingly shaped, two-ended, reversible tool assembly. This tool assembly is sized to slide within the hollow socket, and has a combined drill bit and countersink at one end, and, at the other end, a polygonally shaped opening for accepting a screw driver bit having a shank with a polygonal cross section.

A first embodiment of the present invention includes a magnetic weight bearing prosthetic socket system for coupling a prosthesis to an amputated limb. A pair of magnetic fixtures are used to hold the prosthesis in spaced apart relation with the amputated limb. One of the magnetic fixtures is implanted in the remnant bone and the other magnetic fixture is embedded in the prosthetic socket. The magnetic fixtures are magnetically oriented to oppose one another and are used to transfer loads associated with typical weight-bearing surfaces through the soft tissue covering the remnant bone without having the magnetic structures physically touch one another.A second embodiment of the present invention includes repelling magnetic fixtures implanted within opposing bones in an articulating joint to hold the bones apart during relative articulating movement of the bones in the joint.

In some embodiments, an electromagnetic machine includes a rotor element configured for movement relative to a stator. The rotor element includes a support member, a backing member, and a magnetic pole assembly. The support member includes a first coupling portion. The backing member is formed, at least in part, from a ferromagnetic material and the magnetic pole assembly is configured to be coupled to the backing member. The magnetic pole assembly and/or the backing member include a second coupling portion configured to removably couple the backing member and the magnetic pole assembly collectively to the first coupling portion of the support member.
