Methods, systems and devices for preventing prosthetic articulating surfaces from separating from each other. A containment system according to one embodiment seeks to prevent an implant stem head from dislocating from a prosthetic component while providing an increased range of motion over conventional contrained components. In one embodiment, an implant structural member includes a cavity and an opening having a lip, including a web along a portion of the lip. An implant stem head has a cooperating surface that corresponds with the web, so that when the cooperating surface of the implant stem head is aligned with the web, the head may be inserted into the implant structural member. The implant stem head is then rotated and the femoral stem component attached, thereby preventing dislocation of the head.

The center of curvature of the curved needle is aligned with the rotation axis of the curved needle and engaging means are provided at least at the pointed end of the curved needle for receiving thread.

Structures and methods of manufacturing are disclosed of dislocation free stressed channels in bulk silicon and SOI (silicon on insulator) CMOS (complementary metal oxide semiconductor) devices by gate stress engineering with SiGe and/or Si:C. A CMOS device comprises a substrate of either bulk Si or SOI, a gate dielectric layer over the substrate, and a stacked gate structure of SiGe and/or Si:C having stresses produced at the interfaces of SSi(strained Si)/SiGe or SSi/Si:C in the stacked gate structure. The stacked gate structure has a first stressed film layer of large grain size Si or SiGe over the gate dielectric layer, a second stressed film layer of strained SiGe or strained Si:C over the first stressed film layer, and a semiconductor or conductor such as p(poly)-Si over the second stressed film layer.

A computer system and method provide a systems for representing resource(s) in a computing system environment by creating an object to represent a resource in the computing system environment and assigning an object identifier to the object. The object identifier includes at least a simple name of the object and a home of the object. The system displays at least one representation of the object on a graphical user interface. Each representation of the object includes the simple name of the object and, if a home condition exists for that representation of the object displayed on the graphical user interface, the representation further includes the home of the object, and if a home condition does not exist for that representation of the object, the representation of the object displayed on the graphical user interface does not include the home of the object. The graphical user interface can also provide groups that are transparent and terminal in order to allow visual arrangement of resource representations without effecting those resources.

A bottle stopper is provided having a cylindrical body formed of a resilient, flexible, elastic material that includes a first cylindrical section adapted to be inserted into an opening of a bottle in sealing engagement with the bottle and a second cylindrical section disposed adjacent the first cylindrical section for extending above the opening of the bottle when the first cylindrical section is inserted in sealing engagement with the bottle. An air passageway is disposed adjacent and extends longitudinally along substantially at least the length of the first cylindrical section and along the internal periphery of the cylindrical body. A visual indicator, preferably a spout, is disposed on an outer surface of the second cylindrical section for identifying the relative location of the air passageway with respect to the visual indicator.

In inexpensive structure, a rotation center of a ball portion provided on a rotation shaft is prevented from moving. A universal joint is provided with a rotation shaft (21) having a ball portion (22) provided at an end thereof and a pair of projections (24, 25) formed on a diameter line of the ball portion (22), and a rotation body (26) having guide grooves (28) formed for receiving insertion of the respective projections of the rotation shaft and a holding hole (27) formed for holding the ball portion (22), the ball portion being rotatable about an axis line of the projections and rotatable while inclining the projections along the guide grooves. In the universal joint pins (32, 33) serving as a stopper are provided in the holding hole for inhibiting the ball portion from slipping off.

The invention discloses an automatic regulating apparatus for controller parameters of a servo driver of a motor and a method thereof. The apparatus comprises an inertia identifier, a parameter initial regulator, a parameter checker, a parameter optimizer, a parameter saving and displaying device, a speed controller, a position controller, a torque controller, a PWM (Pulse-Width Modulation) generator and a coded disc. In the invention, the servo driver of an alternating current permanent magnet motor automatically configures the parameters of the position controller and the speed controller according to different rotary inertias of mechanic load, checks and further optimizes the automatically configured parameters through the parameter checker and the parameter optimizer so that the position response and the speed response of the servo driver are relatively optimal. The servo driver of the alternating current permanent magnet synchronous motor automatically regulates the control parameters according to work occasions and achieves ideal control effect. The whole process is manual participation free and completed fully by the servo motor of the alternating current permanent magnet synchronous motor.

A flip-chip type semiconductor light-emitting device having a positive electrode and a negative electrode similar in electrode area and capable of preventing the misalignment of the light-emitting device by utilizing the self alignment effect in manufacturing a light-emitting diode lamp and a printed circuit board for the flip-chip type semiconductor light-emitting device are provided.

Still furthermore, a soldering film is included in each of the electrode pads.

A prosthetic constraining device for use with a hip replacement prosthesis that includes an acetabular cup assembly adapted to be bonded to a patient's pelvis and a femoral stem adapted to be bonded to the patient's femur, where the femoral stem includes a ball component at its proximal end received within the acetabular cup assembly to form a ball joint type coupling, and where the constraining device includes a ring having a central aperture, where the ring is adapted to be mounted to a rim of the acetabular cup assembly so that the femoral stem passes through the central aperture, where the diameter of the central aperture is less than the diameter of the ball component on the proximal end of the femoral stem so that the ring assists in maintaining the ball joint type coupling between the acetabular cup assembly and the femoral stem, and where the ring comprises a biologic material, a biologically reabsorbable material and a combination of biologic, or biologically reabsorbable materials.

An insert for establishing a desired spacing between a pair of succeeding vertebrae and having a body including an extending end for supporting a location associated with a first selected lumbar vertebrae. An opposite extending end supports a spaced apart and opposing location associated with a second successively positioned lumbar vertebrae. Upon pre-positioning the body in an open space established between the vertebrae, an actuating input causes the first extending end to displace outwardly relative to the second end and into contacting support with the vertebrae.

A portable hand-held screw driving tool is provided for use with collated strips of screws. A collated strip of screws enters from the “bottom” area of the tool and runs through a fixed guide along a front area of the tool's handle, and then to a movable slide body having a rotatable sprocket that receives the collated strip, and indexes the strip so a screw can be driven by the tool. Between the slide body and the fixed guide is a flexible strap with a bracket that places tension on the collated screw strip, which prevents the flexible collated strip from becoming substantially misaligned (e.g., bunching, sagging, or becoming tangled) in the area between the fixed guide and the slide body. The collated strip is kept sufficiently taut, regardless of the orientation of the screw driving tool with respect to the ground.
