NIST may enter into a Cooperative Research and Development Agreement (“CRADA”) with the licensee to perform further research on the inventions for purposes of commercialization. The inventions available for licensing are:

Docket No.: 99-021CIP.

Title: Apparatus and Method Utilizing Bi-directional Relative Movement for Refreshable Tactile Display.

Abstract: A refreshable Braille reader apparatus and method are disclosed, the apparatus preferably utilizing a rotating cylinder having endless rows of openings defined therethrough to a display surface with a pin held in each opening and freely movable therein. Static actuators at least equal in number to the rows of openings through the cylinder are maintained at a station adjacent to the surface of the cylinder, and are configured and positioned so that the pins are selectively contractable at either of their ends by different ones of the actuators during cylinder rotation in either forward or reverse direction thereby selectively positioning first ends of the pins relative to the surface of the cylinder to allow streaming of Braille text across a display area in either forward or backward order depending upon selected direction of cylinder rotation.

Docket No.: 01-014US.

Title: Method And Device For Avoiding Chatter During Machine Tool Operation.

Abstract: The invention uses once-per-revolution sampling of the audio (or other appropriate sensor) signal during cutting to detect chatter i.e., unstable machining. The synchronously sampled audio (or other appropriate sensor) machining data is shown on a real-time LED display that allows the user (machinist) to visually detect the onset of chatter and adjust machining conditions. This method of chatter avoidance requires no knowledge of machine dynamics, process specific cutting energy coefficients, or chatter theory; all of which are the key impediments to the successful implementation of high-speed machining on the shop floor. The device Start Printed Page 23443described here requires no interface with the machine tool controller and could be added as an after market supplement. Additionally, it is shown that the use of this device allows determination of the well-known stability lobe diagrams without direct knowledge of the tool point dynamic response or cutting energy coefficients.
