Abstract: The present invention is a catheter actuation handle for deflecting a distal end of a tubular catheter body, the handle including an auto-locking mechanism. The handle comprises upper and lower grip portions, an actuator, and an auto-locking mechanism. The auto-locking mechanism is adapted to hold a deflected distal end of the catheter in place without input from the operator. When the distal end of the catheter is deflected from its zero position, it typically will seek a return to its zero position, and as a result exerts a force on the actuator. The auto-locking mechanism acts by providing a second force that resists this force from the distal end and holds the distal end in place. As a result, the operator does not need to maintain contact with the buttons to maintain the distal end 18 in a set position once placed there by actuating the actuator.

Abstract: The present invention is directed to a method and an apparatus for automatically configuring and/or inserting chip resources for manufacturing tests. A maximum test configuration (“test backplane”) for all IP blocks is created and loaded into a tool suite. When a user issues a request to consume some IP blocks, the request may be checked for legality within the “test backplane”. If a test resource (IP block) is not available for activation, then either the test resource may not be activated or the conflicting resource problem must be resolved so that the test resource may be activated. This may avoid late design surprises. The resources on the platform may already have test structures associated with them. All of these test structures may be associated with the “test backplane”. These pre-exiting test structures may then be connected.

Abstract: Organometallic ceramic precursor binders are used to fabricate shaped bodies by different techniques. Exemplary shape making techniques which utilize hardenable, liquid, organometallic, ceramic precursor binders include the fabrication of negatives of parts to be made (e.g., sand molds and sand cores for metalcasting, etc.), as well as utilizing ceramic precursor binders to make shapes directly (e.g., brake shoes, brake pads, clutch parts, grinding wheels, polymer concrete, refractory patches and liners, etc.). A preferred embodiment of the invention involves the fabrication of preforms used in the formation of composite articles.
