Abstract: A task analysis data store may contain electronic records representing task analysis items for an enterprise. A back-end application computer server may receive, from a remote user device, first step data about task objectives for task identifier and update the task analysis data store. The server may then automatically evaluate the first step data in accordance with a first step data evaluation rule. When the first step data complies with the first step data evaluation rule, the server may permit receipt of second step data about a task analysis and update the task analysis data store. The server may then automatically evaluate the second step data in accordance with a second step data evaluation rule. When the second step data complies with the second step data evaluation rule, the server may permit receipt of third step data about analysis presentation and update the task analysis data store.

Abstract: Variable angle holes in bone plates structured to facilitate the formation of axial compression or tension of a bone, or which can assist in bone distraction. The variable angle hole can extend about a central axis and includes an inwardly extending wedge wall. The variable angle hole can be sized to receive insertion of a fixation element at a location at which a central longitudinal axis of the fixation element is axially offset from the central axis of the variable angle hole by an offset distance at least when the fixation element is initially driven into bone at least in a transverse direction. The wedge wall can be configured to be engaged by a portion of the fixation element in a manner that axially displaces at least one of the bone plate, the fixation element, and/or bone(s) in a direction that can generally reduce or increase the offset distance.

Abstract: A data memory system is described, where there may be an asymmetry in the time needed to write or erase data and the time needed to read data. The data may be stored using a RAID data storage arrangement and the reading, writing and erasing operations on the modules arranged such that the erasing and writing operations may be performed without significant latency for performing a read operation. Where a failure of a memory module in the memory system occurs, methods for recovering the data of the failed module are disclosed which may selected in accordance with policies that may relate to the minimizing the possibility of irretrievable data loss, or degradation of latency performance.

Abstract: Periprosthetic bone fixation plates are disclosed including, for example, periprosthetic proximal femur plate, periprosthetic distal femur plate, periprosthetic humerus plate, periprosthetic ring plate, and periprosthetic troch plate. In use, the periprosthetic bone fixation plates are arranged and configured for use in periprosthetic fractures. That is, the periprosthetic plates include one or more features to facilitate positioning and securement of the bone fixation plate to a patients bone that previously received a surgically implanted orthopedic device or implant such as, for example, an intramedullary nail, a hip prosthesis, a knee prosthesis, etc. In use, the one or more features are designed and configured to facilitate avoidance of the previous surgically implanted orthopedic device or implant. In addition, the periprosthetic bone fixation plates are arranged and configured to facilitate plating of a longer working length as compared to existing bone fixation plates (e.g.

Abstract: A starter generator located within a sump region of a turbofan engine and coupled to an adapter shaft. The adapter shaft rotationally coupled to the high pressure shaft, forward of a high pressure shaft bearing, and secured by a spanner nut. The engine makes use of two pluralities of electrical conductors, the first extends through an electrical conduit defined by a forward strut extending from the sump region to the outward casing, the second extends axially away from the electric starter. Each of the first plurality of electrical conductors makes reversible contact with a respective one of the second plurality of electrical conductors via an elbow/pin connector, producing a tight turn in area of limited space.
