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 asolution 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 personal computer for a handicapped person includes an input panel that is subdivided into a group of fields, with one of the fields designated as a central field for the group. Each field is, in turn, subdivided into nine elements (spaces) comprised of a neutral central element surrounded by eight output elements.

The cursor is always initially located at the center element of the central field. In order to move the cursor to a desired output element, the user: (a) identifies the field in which the desired output character is located, (b) moves the cursor in a first direction to the central element of that identified field, and (c) moves the cursor by one space directly to the desired output element in a second direction oriented either orthogonally or diagonally to the first direction.

The invention described is a system for seismic isolation or vibration of structures which is simple, relatively inexpensive and readily used for smaller structures. It involves use of bearings comprising a ball (10) and ball seats (12, 18) interposed between the structure and its foundation. Either the ball itself (24) or the seat surface (15) on which it rolls is compressible, the resistance to that compression providing a frictional braking force resisting rolling of the ball. This serves to dampen relative movement between the structure and its foundation. There are described several alternative constructions of the friction ball which is the preferred central element in the bearing device. There may be a plurality of balls (44, 47) in each combination of balls and seats.

A precursor yarn or thread is made by passing a central element, e.g., a filament, a tow, or a flat member, through a bath of a binder, such as a low-temperature hot-melt adhesive, and aqueous urethane, or an acrylic material, with which is mixed a quantity of hard-shelled microspheres which expand when heated to a higher temperature. This is then covered by a sheath, e.g, of PVC, polyurethane, polyester, acrylic resin, polycarbonate, polypropylene, or polyethylene in a second bath. When this product is heated to a transition temperature which is characteristic of the microspheres chosen, the microspheres expand, swelling the sheath. Such a precursor could be woven into a fabric and then heated, so that as the yarn expands the fabric mesh becomes tighter, reducing its porosity. This would be useful as a yarn in making papermaker's felts. Heat-expansible threads made similarly would be useful in manufacture of shoes, sails, tents, clothing and other items where porosity is undesirable; that is, the product could be sewn together using the thread of the invention and then heat-treated, causing the thread to expand, sealing the holes made in sewing. Such threads would also be useful for decorative purposes, e.g., as embroidery yarns, and likely for other purposes. The yarns of the invention can also be disposed in a desired position and infused with a hardening resin while heat is applied to cause the microspheres to expand, forming a lightweight and stiff composite structure.
