Artificial intervertebral disc
An artificial intervertebral disc includes housing members including spaced inner surfaces facing each other and oppositely facing outer surfaces for engaging spaced apart vertebral surfaces. Bearing surfaces extend from each of the inner surfaces for engaging each other while allowing for low friction and compression resistant movement of the housing members relative to each other while under compression. Load sharing pads are disposed between the inner surfaces and about at least a portion of the bearing surfaces for sharing absorption compressive loads with the bearing surfaces while limiting the relative movement of the housing members.

Pull-cord and pulley lacing system
A convenient lacing system including a drawing mechanism, pulleys or some other form of low friction lace paths, an attachment point, and a lace. The lace terminates at the attachment point, and follows a path around the outside hemispheres of the pulleys (or through the lace paths), criss-crossing between the two rows of pulleys without the lace overlapping. The pulleys are aligned generally in two rows on either side of an area to be drawn together. A drawing mechanism is attached at the non-terminating end of the path of the lace, and through use of a pull-cord draws in the lace and tightens the item to which the system is attached by drawing the pulleys (lace paths) closer together. The use of pulleys allows the system to distribute tension evenly along the path of the lace, and aids in the convenience of tightening.

A valve is provided having a solenoid coil in an integrally formed magnetic material having a cross-sectional configuration resembling a bundt pan. Such a structure can be stamp-formed and creates an enlarged surface area available for the magnetic flux to the armature at the bottom of the bundt cross-section. However, since the ends of the stamped structure are not relevant to the magnetic circuit, they can be left unfinished. A thin, flat plate armature and an axial flow valve assembly allows for low friction, low mass movement of the valve seal. Placement of the armature and solenoid across a small air gap provides a high force, very fast response time with minimal electrical power consumption.
