An artificial disc prosthesis is provided. The prosthesis of the present invention enables spinal segment alignment by having a variable height across its surface. The variable height is achieved by an asymmetric artificial nucleus or by at least one variable height end plate.

The goggles of the invention utilize a substantially rigid frame with separate top and bottom individually rotatable elements, namely an upper browbar and a lower nosepiece, that firmly capture the lens from above and below. The lens is further secured to the frame by projections on each of the browbar and nosepiece which fit through apertures in the lens. At the top, a post which projects forwardly from the frame is received in the well of the browbar by snap-fit engagement. At the bottom, a prong on the rotatable nosepiece passes through a bottom aperture of the lens and is received in a recess of a bottom portion of the frame by snap-fit engagement. The apertures and cooperating projections are preferably located along the center of a one-piece lens. Thus, the rotatable browbar and nosepiece capture the lens top and bottom by edgewise compression and hold the lens front-to-back.

Disclosed is a videogaming and computer workstation unit, preferably integrated with an ergonomic chair, which permits ease of entry and exit to the chair for users of various sizes, and which permits users to use peripheral devices for operating video games and computers comfortably from a chair integrated with a gaming console.

An aspect of the present invention relates to methods and systems for providing a child-oriented computing system.

A flush poke-through fitting, with both electrical power and data communication access, includes a data jack face plate that can be replaced without disassembly of any other part of the fitting. The data jack face plate is also removable without disruption of power to the electrical outlets. Increased wiring space for flexibility in electrical outlet orientation and improved conductor organization during assembly is also provided by pins that support the electrical contacts in the electrical receptacle when assembled.

The present invention relates to methods and devices for the treatment of disc disease and spinal deformities with an artificial disc replacement.

An unmanned aerial vehicle (UAV) is designed for low-speed, low altitude, long endurance missions typical to UAVs of this size and class. The UAV structure is configured to be substantially impervious to small arms fire and to have a very small representative radar cross-section. The UAV is modular such that the main wings and tail wing assembly are quickly and easily, detached from the fuselage for ease of transport and to provide an airframe that is quickly and easily adapted to any particular mission.

System for monitoring a floating roof of a tank containing a liquid, wherein the system determines a local status of the floating roof in spaced apart sensing element locations. In a hazardous or potentially hazardous environment, there is an on-roof subsystem including a sensing element in each sensing element location, intrinsically safe measuring circuitry coupled a sensing elements and arranged for determining said local status, intrinsically safe radio communication on-roof circuitry coupled for communicating externally of the on-roof subsystem the local, an intrinsically safe power supply circuitry connected to an intrinsically safe and interchangeable energy storage unit for powering the on-roof subsystem. The system further includes monitoring circuitry for receiving the indication of local status and for determining an overall monitored status of said floating and further radio communication circuitry. The on-roof subsystem is wireless in its power supply and communication.

An artificial joint for implantation in humans and animals, the joint comprising a joint body arranged between two base elements which are adapted to be connected to adjoining bone parts. The two base elements comprise horizontal and vertical retaining members respectively, that hold the joint body between them. The joint body comprises curved surfaces arranged to make sliding contact to corresponding curved surfaces of at least one base element. The joint body this way distributes the applied forces over a large surface to withstand the load initiated by the patient. The joint body is kept in position using pins held by retaining members at the base elements. The angle of motion can be predetermined by the design of the implant body to mimic the movement of a normal finger.

A road stand comprising a substantially planar cut-out figure. The figure bears a sign having a design thereon appropriate to attract the attention of passers-by. The figure is supported by a free-standing base.

The invention relates to a fuel injection system for use in internal combustion engines. The injection system has having delivery units (2, 3) for delivering fuel from a fuel reservoir (1) in order to supply at least one high-pressure line (9, 10) to the cylinders of the engine. The at least one high-pressure line (9, 10) supplies a number of fuel injectors (11), which each include an injector nozzle (16) that supplies fuel to a combustion chamber of the engine. The at least one high-pressure line (9, 10) and includes line segments (17, 17.1, 17.2) that connect the individual fuel injectors (11) to one another. The injector bodies (20) of the fuel injectors (11) each have an accumulator chamber (36, 36.1) integrated into them.

A cable integrated guardrail system for highway guardrail. The rail of the system contains at least one cut section placed longitudinally along the panel, and of sufficient dimension as to allow interaction with a cable. Said cut sections also act to reduce longitudinal resistance and safely stop axially impacting vehicles. A cable, which is of sufficient length to extend longitudinally along the entire system, prevents tearing of the rail during lateral impacts and aids in safely redirecting the vehicle away from a hazard.
