Long-term Stability of the NIST Conical Reference Transducer

December 22, 2011
Author(s)
Steven E. Fick, Thomas M. Proctor
The National Institute of Standards and Technology (NIST) Conical Reference Transducer (CRT) is designed for purposes which require frequency response characteristics much more uniform than those attainable with ultrasonic transducers conventionally used

Electrochemical Micromachining of NiTi Shape Memory Alloys with Ultrashort Voltage Pulses

December 8, 2011
Author(s)
Joseph Maurer, John Hudson, Steven E. Fick, Thomas P. Moffat, Gordon A. Shaw
Electrochemical micromachining (ECMM) with ultrashort voltage pulses has been used to fabricate microstructures on a NiTi shape memory alloy (SMA). Because of its unique properties, NiTi is a desirable material for use in various applications including

An IEEE 1451.5-802.11 Standard-based Wireless Sensor Network with Embedded WTIM

May 12, 2011
Author(s)
Eugene Song, Kang B. Lee, Steven E. Fick, Alkan Donmez
This paper introduces a reference implementation of the Institute of Electrical and Electronics Engineers (IEEE) 1451.5-802.11 standard-based wireless sensor network (WSN) developed at the National Institute of Standards and Technology (NIST). The WSN

Electrochemical Micromachining of Hastelloy B-2 with Ultrashort Voltage Pulses

September 8, 2009
Author(s)
Gordon A. Shaw, Joseph J. Maurer, Steven E. Fick, Thomas P. Moffat, J. J. Mallett, John L. Hudson
Electrochemical micromachining (ECMM) with ultrashort voltage pulses, a maskless all-electrochemical micro and nanofabrication technique, has been used to fabricate microstructures on a corrosion resistant nickel-based superalloy, Hastelloy B-2. Because of

Contactless Differential Conductivity Detection

October 12, 2008
Author(s)
Gordon A. Shaw, David J. Ross, Steven E. Fick, Wyatt N. Vreeland
We propose a new technique, contactless differential conductivity detection (CDCD,) to improve the detection limit of contactless conductivity detection for capillary and microchannel electrophoresis. By exploiting a 3-electrode differential configuration

Long-term Stability of the NIST Standard Ultrasonic Source

October 1, 2008
Author(s)
Steven E. Fick
The NIST Standard Ultrasonic Source (SUS) is a system comprising a transducer capable of output power levels up to 1 W at multiple frequencies between 1 MHz and 30 MHz, and an electrical impedance-matching network that allows the system to be driven by a

Precision Ultrasonic Wave Measurements with Simple Equipment

January 1, 2001
Author(s)
Steven E. Fick, C H. Palmer
We describe the design and construction of a relatively simple, inexpensive laser interferometer system for accurate measurements of ultrasonic waveforms in reasonably friendly environments. We show how analysis of a single waveform can provide both the

Ultrasonic Research in the NIST Manufacturing Engineering Laboratory

January 1, 2000
Author(s)
Gerald V. Blessing, Steven E. Fick, Nelson N. Hsu, John A. Slotwinski
The Ultrasonics Standards Group in the Manufacturing Engineering Laboratory of the National Institute of Standards and Technology ( NIST) performs research, develops standards, and offers calibration services in support of United States industry. In this

Ultrasound Power Measurement by Pulsed Radiation Pressure

August 2, 1999
Author(s)
Steven E. Fick
In a specially designed radiation force balance (RFB), low-frequency pulse modulation of the incident ultrasound allows high-accuracy measurement of time-averaged spatially-integrated ultrasound power radiated into a reflectionless water load. Errors

Ultrasonic Research and Applications in the NIST Manufacturing Engineering Laboratory

January 1, 1999
Author(s)
Gerald V. Blessing, Steven E. Fick, Nelson N. Hsu, John A. Slotwinski, D Xiang
The Ultrasonics Group in the NIST Manufacturing Engineering Laboratory performs research, develops standards, and offers calibration services in support of U.S. industry. Pulsed ultrasonic and acoustic emission techniques are pursued for application to

Ultrasonic Power Output Measurement by Pulsed Radiation Pressure

September 1, 1996
Author(s)
Steven E. Fick, Franklin R. Breckenridge
Direct measurements of time-averaged spatially integrated output power radiated into reflectionless water loads can be made with high accuracy using techniques which exploit the radiation pressure exerted by sound on all objects in its path. With an

Ultrasound Power Measurement Techniques at NIST

November 12, 1995
Author(s)
Steven E. Fick
Megahertz-frequency sound waves with submillimeter wavelengths are widely used to probe the interior regions of many types of structures. When human tissues are exposed to ultrasound for diagnostic or therapeutic purposes, the applied power levels must be

Transient Analysis of a Line-focus Transducer Probing a Liquid/Solid Interface

January 1, 1995
Author(s)
Nelson N. Hsu, Gerald V. Blessing, Steven E. Fick, D Xiang
The use of a line-focus transducer operating in pulse-echo mode to probe a liquid/solid interface is a new technique which has many engineering applications. To provide a theoretical basis for multi-echo analysis and interpretation, we use numerical

An Ultrasonic Absolute Power Transfer Standard

March 1, 1984
Author(s)
Steven E. Fick, Donald G. Eitzen, Carl E. Tschiegg, Franklin R. Breckenridge
In response to increased interest in the use of calibrated sources of ultrasonic energy, we have developed a system comprising components grouped to facilitate the accurate transfer of calibration. Electronic circuitry supplied with and built into each
