A control system includes a vision system including an imaging device and a VAR monitoring system configured to determine a power adjustment phase of the VAR process based on the images from the vision system and a process parameter. The VAR monitoring system includes a vision analysis module configured to analyze the images from the vision system to detect a melt marker based on a remelt image process model, and a prediction module configured to predict an operational characteristic of the VAR process that is associated with the power adjustment relative to a melt marker location and a remelt prediction model. The VAR monitoring system is configured to initiate the power adjustment phase in response to the melt marker satisfying a predetermined melt marker condition, the operational characteristic of the VAR process satisfying a predetermined operational condition, or a combination thereof.

Video analysis-based algorithm for triggering power cutback in vacuum arc remelting

Dura shields in accordance with embodiments of the invention are disclosed. In one embodiment, a dura shield includes a shield configured to protect a patient's dura during an interbody procedure, a tether coupled to the shield and configured to position the shield, and an anchor coupled to the shield and configured to attach to a surface within the patient during the interbody procedure. A variety of sensors can be incorporated into the dura shield in order to monitor a patient during the procedure.

Dura shield

A method of vacuum arc remelting an ingot provided in a crucible assembly having an electrode includes generating a rotating magnetic field normal to a longitudinal axis of the ingot and localized to an arc region during remelting. The rotating magnetic field interacts with a melting current to produce a rotating arc directed radially outward.

Compact coil assembly for a vacuum arc remelting system

A vacuum arc remelting system for forming an ingot from an electrode is provided that includes a crucible assembly configured to accommodate the electrode and the ingot, an electromagnetic energy source arranged about the crucible assembly, and a lift mechanism operable to move the electromagnetic energy source along a longitudinal axis of the crucible assembly. A magnetic field generated by the electromagnetic energy source is localized to an arc region during remelting, and in one form, the electromagnetic energy source is a coil assembly having a magnetic core and a plurality of coil pairs wrapped around the core, wherein the coil assembly is operable to generate a magnetic field from the coil based on electric current flowing in the plurality of coil pairs.
