An artificial disc device for replacing a damaged nucleus is disclosed. In one form, the device may be inserted in components such that the device may be assembled within and retained by the natural annulus therein. In another form, the device may be inserted into the natural annulus in a collapsed or compressed state or arrangement and then be expanded within and retained by the annulus therein. In a further form, the device may be provided with a releasable connection so that the device may be connected in an insertion configuration and may be released in an operable configuration. Insertion tools and methods are also disclosed.

Disclosed herein is a temporary well isolation device, which is sealingly disposable in downhole tubing, and which has a housing with an axial passage. The temporary well isolation device also has frangible barrier element within the housing, where the frangible barrier element is sealingly engaged in the passage blocking fluid flow through the passage. The frangible barrier element bears a load from fluid pressure. The temporary well isolation device also has a disengagable constraint in contact with a frangible barrier element so as to redirect the load on the frangible barrier element from a first component of the load to a second component of the load, thereby preventing rupture of the frangible barrier element. Also disclosed herein is a method for disintegrating a frangible barrier element disposed in a passage of a temporary well isolation device.

This invention describes an improved high bandwidth chip-to-chip interface for memory devices, which is capable of operating at higher speeds, while maintaining error free data transmission, consuming lower power, and supporting more load. Accordingly, the invention provides a memory subsystem comprising at least two semiconductor devices; a main bus containing a plurality of bus lines for carrying substantially all data and command information needed by the devices, the semiconductor devices including at least one memory device connected in parallel to the bus; the bus lines including respective row command lines and column command lines; a clock generator for coupling to a clock line, the devices including clock inputs for coupling to the clock line; and the devices including programmable delay elements coupled to the clock inputs to delay the clock edges for setting an input data sampling time of the memory device.

An interbody osteogenic fusion device is provided that includes a rigid elongated central element and a pair of opposing bone engaging members. The device promotes fusion bone growth in the space between adjacent vertebrae. In one aspect, a cylindrical end cap is coupled to one end of the central element. The opposing bone engaging members are configured to contact and support the adjacent vertebrae. The opposing bone engaging members are coupled at opposite sides of the central element and extend from the end cap to the other end of the central element. The central element, cylindrical end cap, and bone engaging members define opposite cavities for containing osteogenic material.

A movable machine, for example a saw, has a light construction using composite materials such as fiber reinforced resins and a closed cell foam. The saw may have a housing formed from multiple skins of the composite materials in which is located the closed cell foam. Metallic inserts may be used to bond to either or both of the foam and the composite skin to accept working components. A saw is also described which uses gears sharing the same support element.

A display structure has a base with non-rotatable sides and rotatable sides containing a first part with and a second part, the parts fastened by a rotatable fastener; a post containing a first and second face, the two non-rotatable sides fastened to the lower end of the posts, and the rotatable sides fastened to the lower end of the posts, a rotatable fastener specially located so as to allow rotation of the parts in regards to the post; and a top with non-rotatable and rotatable sides, the non-rotatable sides of the top fastened to the top of the post, the rotatable side of the top fastened to the non-rotatable sides of the top with rotatable fastener, said rotatable fastener of the top are specially located to allow rotation of the parts in regards to the non-rotatable side.

An interbody osteogenic fusion device is provided that includes opposite end pieces with an integral central element. The end pieces are sized to maintain the height of an intervertebral disc space. The central element has a much smaller diameter so that the osteogenic fusion device forms an annular pocket around the central element. An osteogenic material is disposed within the annular pocket between the opposite end pieces. In one embodiment, the osteogenic material constitutes a collagen sheet soaked in a solution containing a bone morphogenetic protein. The osteogenic fusion device is configured so that the osteogenic material is in direct contact with the adjacent vertebral bone. In addition to the enhanced area of contact between the vertebral bone and the fusion material, the inventive osteogenic fusion device reduces stress-shielding and minimizes the radiopacity of the implant so that growth of the fusion mass can be continuously assessed. In yet another embodiment, the osteogenic fusion device includes at least one end piece with a truncated surface. The osteogenic fusion devices of the present invention may be combined with other fusion devices to form an implant system. The implant system includes at least one load bearing member having a truncated surface configured to nest within another load bearing member, preferably the load bearing, osteogenic fusion device of the present invention. The invention also provides implant systems comprising adjacent load bearing members connected to one another to resist lateral separation. Methods of promoting fusion bone growth in the space between adjacent vertebrae utilizing devices and systems of the invention are also described.

A movable machine, for example a saw, has a light construction using composite materials such as fiber reinforced resins and a closed cell foam. The saw may have a housing formed from multiple skins of the composite materials sandwiching the closed cell foam. Metallic inserts may be used to bond to either or both of the foam and the composite skin to accept working components. A saw is also described which uses gears sharing the same support element.

A foldable knee-brace for support a table having an edge secured to a wall. The knee-brace includes first and second struts. The second strut includes a pair of parallel bars. Ends of the bars are disposed on opposite sides of an end of the first strut, and hinged thereto. Pockets formed into each bar's side surface are positionable adjacent to the first strut's end for receiving an end of a locking-pin carried at and projecting outward from the first strut's end. Ends of the first strut and second strut's bars furthest from the hinge are equipped for hinged fastening respectively to:a. the table near a second edge thereof furthest from the wall; andb. to the wall below the table's first edge.Configured in this way, the knee-brace folds between the table and the wall when the table is collapsed adjacent to the wall.

A die cushion device includes a cushion pad, a support section, a servomotor, and a shock absorber device. The support section supports the cushion pad. The servomotor raises and lowers the support section for raising and lowering the cushion pad. The shock absorber device includes a damping section and relieves shock between the cushion pad and the support section. The damping section generates reaction force in accordance with the relative speed of the cushion pad with respect to the support section.
