Abstract: Whether or not protection circuitry for a span-powered remote digital subscriber loop unit is properly connected to earth ground is determined by the deliberate assertion and detection of a ground fault from a central office line card location. The span-powered remote unit is augmented to place a controllable conduction path in circuit with the span-powered loop and an earth ground pin. If the earth ground pin has been properly connected to earth ground, applying the conductive path will place a ground fault on the span, which is detected by a ground fault detector within the central office line card. If the ground fault detector does not detect a ground fault in response to the application of the conductive path, the line card forwards a negative ground fault event message to a test center, so that a service technician may be dispatched to the remote unit to correct the problem.

Abstract: The present invention provides hydrogel coated, implantable medical devices and methods of coating hydrogels onto implantable medical devices. In one embodiment, a hydrogel coated medical device is formed by physically treating a surface of the medical device, chemically treating the surface, applying a hydrogel precursor and then crosslinking the hydrogel precursor to form a hydrogel coating on the surface of the medical device. The present invention may be particularly applicable for coating articulating surfaces on implantable medical devices such as artificial joints.

Abstract: An improved method and apparatus for reducing a hip fracture utilizing a minimally invasive procedure which does not require incision of the quadriceps. A femoral implant in accordance with the present invention achieves intramedullary fixation as well as fixation into the femoral head to allow for the compression needed for a femoral fracture to heal. To position the femoral implant of the present invention, an incision is made along the greater trochanter. Because the greater trochanter is not circumferentially covered with muscles, the incision can be made and the wound developed through the skin and fascia to expose the greater trochanter, without incising muscle, including, e.g., the quadriceps. After exposing the greater trochanter, novel instruments of the present invention are utilized to prepare a cavity in the femur extending from the greater trochanter into the femoral head and further extending from the greater trochanter into the intramedullary canal of the femur.

Annealing the toner further improves the heat cohesion and morphology of the toner.

Abstract: A multi-point support system with self-aligning trunnions to carry, on a cradle frame, a rotatable cylindrical drum having a pair of trunnion rings spaced along a central longitudinal axis. A thrust bearing connected to the frame engages a trunnion ring to accommodate any horizontal thrust load for an inclined cylindrical drum. Each self-aligning trunnion includes a base plate on which is mounted a trunnion roller with an axis of rotation substantially parallel to the central longitudinal axis of the cylindrical drum. A pair of bearing supports are connected to the base plate transversely with respect to the longitudinal axis of the drum in order to permit arcuate movement of the base plate about one bearing support and to permit tilting movement of the base plate about a transverse axis through the bearing supports. The arcuate and tilting movements of the base plate permit the trunnion roller to maintain full tangential contact with the trunnion ring.
