Abstract: Embodiments of the present invention include a convertible prosthesis that is capable of conversion from a humeral head replacement to a reverse reconstruction without any removal of parts integrated into the patient's bony anatomy (e.g. implant stems). A desired overall implant inclination angle may be achieved by matching various implant stems with various reverse inserts, thus permitting a resection surface to be matched with an implant stem selection while also permitting a desired overall implant inclination angle to be achieved through the selection of an appropriate insert.

Abstract: A stemless humeral shoulder assembly having a base member and an anchor advanceable into the base member. The base member can include a distal end that can be embedded in bone and a proximal end that can be disposed at a bone surface. The base member can also have a plurality of spaced apart arms projecting from the proximal end to the distal end. The anchor can project circumferentially into the arms and into a space between the arms. When the anchor is advanced into the base member, the anchor can be exposed between the arms. A recess can project distally from a proximal end of the anchor to within the base member. The recess can receive a mounting member of an anatomical or reverse joint interface.

Abstract: A controlled-clearance sealing compressor device that provides precision rotor centering directly with respect to the stator housing, vane centering with respect to rotor (not the stator) and the dynamic balance design of the gliders required for practical single and dual vane devices. The devices uses roller bearings to control the radial position of the vane and control rods or pins are used to control axial positioning of the vane, its ‘centralization’ with respect to the rotor and the endplates. The positive displacement rotary vane compressors and vacuum pumps have friction reduction, efficiency enhancement and exceedingly long operating life as a result of the non-contact gas sealing of the process gas within the rotary vane compressors and vacuum pumps. In an embodiment the positive displacement compressing device is used in transportation vehicles.

Abstract: A system of determining an impairment level of a vehicle operator and preventing operation of the vehicle in an impaired state and method of using the same that comprises a key portion to initiate the starting of the vehicle, an electrical source to power the system, a random pattern generator, a display, a user input to allow the user to attempt to replicate the generated random pattern, a processor that compares data from the user input to the generated random pattern to determine if the input sufficiently matches the generated random pattern, and an access preventing feature disabling the key portion from starting the vehicle unless the processor determines the user input sufficiently matches the generated random pattern.

Abstract: A valving system for reversing flow in a compressing device. The reversible compressor includes a reversible drive motor for reversing a rotational direction of a rotor, a first and second port located in a left and right side of a stator, respectively, and a first and second manifold located on a right a left side of said reversible compressor, the first and said second manifold includes a corresponding first and second inlet valve moveable between an open and closed position. A valving system between said first and said second manifold switches one of the first and second inlet valve to an open position to open a corresponding first or the second port for directional flow corresponding to the rotational direction of the rotor. In a first embodiment the valving system is a pressure-actuated control element and in a second embodiment the valving system includes a solenoid.

Abstract: A rotating fuel cell has a mounting with bearing means defining a rotary axis. A shaft with a longitudinally-extending bore is supported for rotation on the bearings. At least one PEM fuel cell assembly is mounted on the shaft and insulated therefrom, and also has a gas passageway in register with a radially-extending port in the shaft. Connections are provided for admitting hydrogen gas to the hollow bore. Air (oxygen) is supplied to the exterior of the PEM fuel cell assembly. The shaft and the PEM fuel cell assembly is rotated about the axis.

Abstract: A single vane gas displacement apparatus comprises a stator housing with a right cylindrical bore enclosing an eccentrically mounted rotor which also has a radial slot in which is movably radially positioned a single vane. The vane is tethered to antifriction vane guide assemblies concentric with the housing bore. Then vane has a preselected center of gravity located proximate to the housing bore axis. An option is to have a port in said vane for ducting high-pressure gas to the inlet side to react against the rotor slot to reduce vane contact therewith.

Abstract: A non-contact vane-type fluid-displacement machine includes a stator housing having an annular interior surface defining an interior bore and a rotor supported in an eccentric position in the interior bore of the stator housing relative to the annular interior surface thereof to undergo rotation relative to the stator housing about a central rotational axis.
