In one aspect there is provided a medical navigation system, comprising a computing device having a processor coupled to a memory, a tracking camera for tracking medical instruments, and a display for displaying an image. Tracked medical instruments may have attached thereto an indicator device having a visual indicator. The indicator device is positioned in view of a user during the medical procedure, and is configured to receive, from the medical navigation system, data indicating a quality of the tracking of the one or more instruments, and to display, using the visual indicator, the data indicating the quality of the tracking.

An arrangement for controlling bevel etch rate during plasma processing within a processing chamber. The arrangement includes a power source and a gas distribution system. The arrangement also includes a lower electrode, which is configured at least for supporting a substrate. The arrangement further includes a top ring electrode positioned above the substrate and a bottom ring electrode positioned below the substrate. The arrangement yet also includes a first match arrangement coupled to the top ring electrode and configured at least for controlling current flowing through the top ring electrode to control amount of plasma available for etching at least a part of the substrate top edge. The arrangement yet further includes a second match arrangement configured to control the current flowing through the bottom ring electrode to control amount of plasma available for at least etching at least a part of the substrate bottom edge.

An instrument for use in a joint replacement procedure includes a trial head that corresponds to the head of an orthopaedic joint component having an upper surface defined by a curved surface and a bore formed in a lower surface and a trial connector for connecting the trial head to a stem part of the orthopaedic joint component which is intended for location in the intramedullary cavity of a bone. The trial connector can be fitted into the bore in the trial head at a variable angular orientation.
摘要:
A plasma etch processing chamber configured to clean a bevel edge of a substrate is provided. The chamber includes a bottom edge electrode and a top edge electrode defined over the bottom edge electrode. The top edge electrode and the bottom edge electrode are configured to generate a cleaning plasma to clean the bevel edge of the substrate. The chamber includes a gas feed defined through a top surface of the processing chamber. The gas feed introduces a processing gas for striking the cleaning plasma at a location in the processing chamber that is between an axis of the substrate and the top edge electrode. A pump out port is defined through the top surface of the chamber and the pump out port located along a center axis of the substrate. A method for cleaning a bevel edge of a substrate is also provided.

A transcowl for a gas turbine engine thrust reverser includes an arcuate outer wall; an arcuate inner wall; and an arcuate baffle positioned between the inner and outer walls at a forward end of the transcowl. The baffle has an arcuate cross-sectional shape which defines a forward-facing interior area. An arcuate forward seal is carried at a forward end of the inner wall. The forward seal includes a plurality of axially-extending, spaced-apart arcuate seal teeth which collectively define a labyrinth seal.
摘要:
An apparatus and method for suppressing dynamic instability in a bleed duct of a gas turbine engine includes a fan bypass duct configured to permit a flow of air through the gas turbine engine. The fan bypass duct defines a fan duct surface, and the bleed duct has an inlet in fluid communication with the fan bypass duct and a flow control valve having an opened position and a closed position. A flow diverter is positioned on the fan duct surface proximate the inlet of the bleed duct and diverts the flow of air from the inlet when the flow control valve is closed, while permitting a portion of the flow of air to enter the inlet when the flow control valve is opened.
摘要:
A heat transfer system is provided for a turbine engine of the type including an annular inlet cowling. The heat transfer system includes at least one heat pipe disposed in contact with an interior of the casing. The heat pipe is thermally coupled to a heat source, such that heat from the heat source can be transferred through the heat pipe and into the inlet cowling.
