Abstract: A spinal implant which is configured to be deployed between adjacent vertebral bodies. The implant has at least one extendable support element with a retracted configuration to facilitate deployment of the implant and an extended configuration so as to expand the implant and effectively distract the disc space, stabilize the motion segments and eliminate pathologic spine motion. The implant has a minimal dimension in its unexpanded state that is smaller than the dimensions of the neuroforamen through which it typically passes to be deployed within the intervertebral space. The implant is provided with a locking system having a plurality of linked locking elements that work in unison to lock the implant in an extended configuration. Bone engaging anchors also may be provided to ensure secure positioning.

The implant has at least one extendable support element with a retracted configuration to facilitate deployment of the implant and an extended configuration so as to expand the implant and effectively distract the disc space, stabilize the motion segments and eliminate pathologic spine motion. Angular deformities can also be corrected, and natural curvatures restored. Preferably, the implant has a minimal dimension in its unexpanded state that is smaller than the dimensions of the neuroforamen through which it typically passes to be deployed within the intervertebral space. The implant is provided with a locking system preferably having a plurality of locking elements to lock the implant in an extended configuration.

Abstract: An insertion handle for medical implants includes a handle with an elongate shaft extending therefrom and connection means for the implant disposed at the end of the shaft opposite the handle. The connection means includes a pivotable attachment for the implant that is controlled remotely from the handle. Both angle of the implant with respect to the handle and shaft as well as the attachment may be separately controlled and adjusted. Remote angular adjustment facilitates insertion of implants in to small surgical sites because the orientation of the implant may be repeatedly, remotely adjusted as the implant is inserted. Connectors may also be provided at the engagement surface between the handle and implant in order to provide communication with the implant or surgical site. The connectors also may serve as torque bearing members to avoid the need for separate torque bearing means such as keyways and the like.

Abstract: A gaseous carburetor or fuel control system includes a fuel metering assembly, a venturi mixer assembly, a throttle assembly, and an electronic control unit. The control unit controls the fuel metering assembly in a closed loop manner based on detected gas and air pressure to an air/fuel mixing venturi. An electronic governor which controls the throttle valve may also be controlled by the same control unit which controls the fuel metering assembly, using a separate control loop.

Abstract: A spinal implant which is configured to be deployed between adjacent vertebral bodies. The implant has at least one extendable support element with a refracted configuration to facilitate deployment of the implant and an extended configuration so as to expand the implant and effectively distract the disc space, stabilize the motion segments and eliminate pathologic spine motion. The implant has a minimal dimension in its unexpanded state that is smaller than the dimensions of the neuroforamen through which it typically passes to be deployed within the intervertebral space.

Abstract: A gas turbine powerplant for a V/STOL aircraft in which a vectorable exhaust nozzle at a forward part (eg. nose) of the aircraft selectably receives a supply of cold fan air through a duct leading from the fan through a passageway (28) coaxial with the engine axis and located within the hub of the fan (12), with the aid of controllable flaps and diverters (26, 30).

Abstract: A first light is moved and illuminated by an x-y plotter mechanism on a rear projection screen under computer control so as to be continuously fixated by an eye of a test subject. The computer also causes one or ones of fixed-position second lights, typically sixteen in number positioned in a regular array, to momentarily illuminate at various times corresponding to various positions of the moving first light. The test subject indicates detection or non-detection of the momentary illuminations to the computer by voicing the numbers "1", "2", "3", etc. From successive illuminations and test subject responses the computer is able to survey the entire visual field of each subject's eye in all directions. The surveyed visual field is plotted on graph paper with the same x-y plotter mechanism that is otherwise and at other times used for moving the first light source.
