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.

Disclosed is a thermogelling biodegradable aqueous polymer solution useful in providing a bioactive agent delivery system. The present invention provides a thermogelling biodegradable aqueous polymer solution with a polyethylene glycol (PEG) block and a biodegradable polyester block, where the blocks are linked to form a polymer of a general structure comprising the formula of A_n(B), where n is greater than 2 and A is selected from the group consisting of a polyethylene glycol block and a biodegradable polyester block, B is selected from the group consisting of a polyethylene glycol block and a biodegradable polyester block, and A is different from B.

A modular plastic floor tile has a body of a first polymer compound and features overmolded onto the body from a second polymer compound. The compounds may be different from each other in hardness and/or color. The features may include raised pads on the upper surface and/or skins on support member cores downwardly depending from the tile lower surface. The pads on the upper surface may be injection-molded from the lower surface through through-holes. Lateral edges of the tile are provided with latches which fit into loops with an interference fit. The loops flex in order to impose a compressive force on mating tile edges. The tile may have an overmolded peripheral seal.

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.

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.

The present invention provides a rapid rig-up and rig-down pipe stand building and racking system that is capable of being retrofit to an existing drilling rig. In particular, the invention relates to a horizontal to vertical pipe delivery machine that is mountable to a drilling rig. The horizontal to vertical machine delivers sections of pipe to a pair of drilling rig mounted elevators. The elevators receive and vertically translate the sections of pipe. A power tong may be used to make connections between the sections of pipe to form a pipe stand, and may also break the connections of the pipe stand. A drill floor mounted pipe racking system receives the connected drill pipe from the elevators. A pipe racking system that may be used in conjunction with the stand building system is capable of controlled, rapid, and precise movement of multiple connected sections of pipe.

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.

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.

A prefabricated panelization system having a floor or roof component and a frame component. In particular, the floor or roof component includes a deck member, which can be made of deck sections, profiles, or panels. For example, the deck member can be made of continuous panels that cover the desired width and length of the floor or roof component without intermediate beams between supporting elements. Alternatively, the deck members can be made of individual or panelized sections that are combined in juxtaposed relation to form the desired width and length. The frame component includes opposing horizontal support channels that are attached to opposing columns, respectfully.

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 pocke 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.
