Abstract: An approach for managing log messages. In this approach, a hierarchical structure identifies primary and secondary relationships between the log messages. In this approach, primary log messages in the log messages that has one or more secondary log messages is identified using the hierarchical structure. One or more pointers are added to each primary log message in the log messages having the one or more secondary log messages. Each pointer points to a secondary log message in the hierarchical structure. The one or more secondary log messages are removed from the log messages to form remaining log messages. Header information from log message headers and content information from log message content in the remaining log messages are saved to form compressed log information.

Abstract: Various systems and methods are presented regarding interrupting a write operation to enable a read operation to be performed on a digital tape system. An initial write operation to the tape can be paused, a read operation performed on a previously written data file conducted, and upon completion of the read operation, the write operation can be recommenced. Interrupt points can be positioned within respective data blocks. Based upon knowledge of the amount of data written during the initial write operation, a position P can be determined (relative to the location of the nearest prior interrupt point) such that when the tape is advanced to place the tape head in a position to recommence the write operation after the read operation has been performed, the tape can be positioned such that the tape head is at position P. Accordingly, interruption of the write operation enables random access of the tape.

Abstract: Aspects of the invention include generating a plurality of predictions that each define a plurality of future inputs for a model. A deviation curve is generated by determining a distance between each prediction of the plurality of predictions and a respective known data point of a plurality of known data points. One or more points in the deviation curve are sampled and the sampled points are compared to a low threshold and a high threshold. A judgement is determined for each prediction to determine whether the respective prediction will be accepted or denied as an input to the model. The future inputs for the model are modified based on the judgments.

Abstract: An implant delivery handle, a delivery system and a method of operation thereof are disclosed. The implant delivery handle is able to switch an inner catheter (1) between unlocked and locked configurations through pivoting a locking knob (43) about an axis of the inner catheter (1) to cause a locking part (42) to exert or withdraw a radial pressure on the inner catheter (1). The implant delivery handle has a simplified structure and can be operated more easily. Moreover, the locking knob (43) for the inner catheter (1) and the control handwheel (33) for the flexible catheter (2) employ distinguishable designs, which effectively prevent a surgeon from being confused with the two actions.

Abstract: The present invention provides an implant delivery handle, an implant system, a delivery system and a method of operation thereof. The implant delivery handle includes two conveyance sub-systems both oriented along an axial direction of a catheter assembly, in which a distal one is coupled to a proximal portion of an outer tube in the catheter assembly, and a proximal one is coupled to a proximal portion of an inner tube in the catheter assembly.
