Error Compensation for CMM Touch Trigger Probes

October 1, 1996
Author(s)
William T. Estler, Steven D. Phillips, Bruce R. Borchardt, Ted Hopp, G Witzgall, M Levenson, K Eberhardt, Marjorie A. McClain, Y Shen, X Zhang
We present the analysis of a simple mechanical model of a common type of kinematic seat touch trigger probe widely used on modern coordinate measuring machines (CMMs). The model provides a quantitative description of the pretravel variation or probe-lobing

Evaporation of a Small Aqueous Suppressing Agent Droplet (NISTIR 5904)

October 1, 1996
Author(s)
W. S. Chien, Jiann C. Yang, M D. King, William L. Grosshandler
Due to its ozone-depleting potential, halon 1301 (CF3Br) has been banned from production under the Montreal Protocol. The research for halon replacement(s) has led to the reconsideration of using water in certain applications. However, under cold storage

Impedance Mismatch Effects on Propagation Constant Measurements

October 1, 1996
Author(s)
Donald C. DeGroot, Dave K. Walker, Roger Marks
By measuring propagation constants of coplanar waveguide transmission lines, we show the significant systematic errors of common measurement techniques when the characteristic impedance of the lines does not match the reference impedance of the instrument.

International Intercomparison of Horn Gain at X-Band

October 1, 1996
Author(s)
Carl F. Stubenrauch, Allen C. Newell, Andrew G. Repjar, Katherine MacReynolds, Douglas T. Tamura, F. Holmlarsen, J. Lemancyzyk, R. Behe, G. Portier, J. C. Zehren, H. Hollman, J. D. Hunter, David Gentle, Jan P. deVreede

NIIIP Reference Architecture - Glossary

October 1, 1996
Author(s)
Peter O. Denno
The National Industrial Information Infrastructure Protocols (NIIIP) Consortium is a collection of companies, government and academic institutions developing protocols and a reference architecture to enable virtual enterprises. This paper, a glossary, is

Quantum-state-resolved 2-level femtosecond rotational coherence spectroscopy: Determination of rotational constants at medium and high J in Li 2 , a simple diatomic system

October 1, 1996
Author(s)
R M. Williams, J M. Papanikolas, J , . Rathje, S R. Leone
Rotational wave packet recurrences originating form a single 2-level coherent rotational superposition are observed in the E( 1Σ + g) state of Li 2. The rotational wave packet is created by ultrafast laser excitation from a specific ro-vibrational level in

Stylus-Laser Surface Calibration System

October 1, 1996
Author(s)
Theodore V. Vorburger, Jun-Feng Song, T Giauque, Thomas Brian Renegar, Eric P. Whitenton, M Croarkin
A stylus-laser surface calibration system was developed to calibrate the NIST sinusoidal roughness Standard Reference Materials (SRM) 2071-2075. Step height standards are used to calibrate the stylus instrument in the vertical direction, and a laser
