Abstract: A total hip arthroplasty system includes a medullary nail for insertion into a femoral canal of the femur, straight medullary nail with longitudinal axis, screw holes perpendicular to the longitudinal axis, and a hole having a transverse axis. The system also includes a bone anchor having a threaded opening for a cut-off femoral neck, a neck screw having a seat for the femoral head and a threaded shaft, a femoral head, and an acetabular cup assembly. A jig is provided for implanting the system and includes a guide that orients relative to the nail, attachment hardware, a rail adapted to extend parallel to the transverse axis of the nail, and a second guide slidably displaceable along the rail. The system provides significant adjustability and retains maximum bone for the possibility of revision.

Abstract: A system and method provide for installation and setup of a set-top box (STB) in a Digital TV network includes a mobile device running a mobile application, an operator application, and a display configured to display video from the STB. A status of the STB is determined and encoded into an optically scannable graphic displayed by the display. The optically scannable graphic is scanned with an optical device in communication with the mobile device and the status of the STB is decoded. The status of the STB is transmitted to the operator application compared with an acceptance criteria.

Abstract: The invention discloses a composite layer bushing used as supplementary material feeder in mold cast processes, which decreases the heat loss between the walls thereof and the sand of the mold. The bushing of the invention comprises two concentric layers, an inner exothermic layer and an outer insulating layer, wherein said layers form an upper section corresponding to a hollow cylinder, and a lower section corresponding to the bottom of the bushing.
