The present invention provides a device and methodology for use in spinal fusion surgeries. An implant is proved for forming a rigid structure between adjoining vertebrae in a patient. The implant is a cage defined by at least a first end, second end, first side, and second side surface, wherein first and second side surfaces extend substantially parallel to each other to span a space between adjoining vertebrae and first and second ends interconnect the first side surface and second side surface. The cage incorporates one or more flexible joints that allow the cage to be deformed for insertion into a patient. The ability to deform the cage allows a greater ease and flexibility in inserting and positioning the implant.

A pressure swing adsorption (PSA) system including a first group of PSA modules having a plurality of first PSA modules, and a second group of PSA modules having a plurality of second PSA modules. The system includes a feed gas manifold, a product manifold, and a waste manifold connected to the first PSA modules and the second PSA modules. Each first PSA module operates on a first PSA cycle in synchronization with the other first PSA modules, and each second PSA module operates on a second PSA cycle in synchronization with the other second PSA modules. The first PSA cycle is offset from the second PSA cycle. The PSA modules include a plurality of pressurized adsorbent chambers, an inlet manifold, and an outlet manifold. A rigid structure is provided that connects the inlet manifold to the outlet manifold, and structurally joins the inlet and outlet manifolds to the adsorbent chambers.

A lightweight ballistic resistant rigid structural panel especially for use in aircraft interiors is disclosed. The rigid structural panel is made up of a core layer including a plurality of sheets of flexible, high-tensile strength fabric interleaved with a plurality of sheets of a thermal-fusible film adhesive, and a sheet of cushioning material adhered to the plurality of sheets of flexible, high-tensile strength fabric. Fiber-reinforced face skins are adhered to exterior surfaces of the panel core for structural strength and rigidity. The rigid structural panel is capable of resisting ballistic attack from handguns and like weapons, while maintaining a high degree of strength and rigidity.

An active bolster for an automotive vehicle has base wall for mounting against a rigid structure of the vehicle. A front wall overlies the base wall and forms an interior trim piece of the vehicle. The base wall has a first surface facing the front wall, and the front wall has a second surface facing the base wall. The base wall and front wall are joined around a closed perimeter to form an inflatable bladder with an initial open space between the first and second surfaces. The base wall includes a wide rib projecting from the first surface continuously along the closed perimeter, the wide rib having a minimum radial width along the closed perimeter equal to a first predetermined radial width. The front wall includes a plurality of narrow ribs projecting concentrically from the second surface continuously along the closed perimeter. Each narrow rib is welded to the wide rib, and each narrow rib has a respective radial width at each respective location along the closed perimeter less than half the radial width of the wide rib at the respective location.

A chair includes a first leg, a second leg pivotally mounted on the first leg, and a seat frame mounted on the first leg and the second leg by a plurality of detachable connecting members. Thus, the first leg, the second leg and the seat frame are assembled and disassembled easily and conveniently, thereby facilitating the user mounting the chair. In addition, the seat frame is combined with the first leg and the second leg by the connecting members, thereby simplifying the working procedure.
