Abstract: An implant for use in spinal surgery comprises a resilient element having an inflatable cavity. It is formed of a biologically compatible material and is arranged for placement between end plates of adjacent vertebra. The implant may also include a wound disc replacement element. A method of performing spinal surgery on a patient comprises securely mounting a patient onto a patient support table; imaging a spinal region of the patient; building up a three-dimensional image file of the spinal region of the patient; storing the image file; and utilizing the image file for planning and carrying out computer controlled spinal surgery on the patient utilizing the implant. A computer-controlled surgical implant system comprises a steerable endosurgical implanting assembly operative to install the implant at a desired location in a patient; and a computerized controlled, which operates the steerable endosurgical implanting assembly.

Abstract: Hinge apparatus which includes first and second hinge members (12, 14) arranged for relative rotation about a hinge axis (18), and fluidic actuator apparatus (24). The fluidic actuator apparatus includes a force transfer member (22) having a first end attached to the first hinge member at an anchor location spaced from the hinge axis, and expandable pillow (25) apparatus associated with the force transfer member and operative to expand when exposed to a fluidic pressure thereby to apply a force along the force transfer member to the first hinge member so as to cause rotation of the first hinge member relative to the second hinge member in at least a first direction.

Abstract: Watercraft including a hull (10), a plurality of foils (12) mounted on the hull for engaging a water surface, and shock absorbing means (16, 18) associated with the plurality of foils for coupling the plurality of foils to at least a portion of the hull and providing at least partial absorption of shock received from waves.

Abstract: A water vessel comprising a hull, at least one retractable hydrofoil apparatus configured for disposition in an extended orientation for vessel operation in a hydrofoil mode and for disposition in a retracted orientation for vessel operation in an undersea mode and propulsion apparatus providing propulsion of the vessel in both the undersea mode and the hydrofoil mode.

Abstract: Hydrofoil marine apparatus comprising a hull, a pair of hydrofoils, each including first and second planar surface portions, pivotal mounting apparatus for mounting the pair of hydrofoils onto the hull, and apparatus for selectably and variably determining the dihedral angle between the first and second planar surface portions.
