Object-oriented Model for IEEE 1588 Standard

October 1, 2007
Author(s)
Kang B. Lee, Eugene Song
The IEEE 1588 standard specifies a protocol enabling precise synchronization of clocks in measurement and control systems implemented with technologies such as network communication, local computing, and distributed objects. This paper describes an object

Wireless Sensor Network Based on IEEE 1451.0 and IEEE 1451.5-802.11

August 1, 2007
Author(s)
Kang B. Lee, Yuyin Song
This paper describes a wireless sensor network (WSN) based on the Institute of Electrical and Electronics Engineers (IEEE) s 1451.0, 1451.5, and 802.11 standards. The implementation of the IEEE-based WSN was developed at the National Institute of Standards

Open Architecture Software Design for Online Spindle Health Monitoring

May 1, 2007
Author(s)
Kang B. Lee, Robert Gao, Ruqiang Yan, Li Zhang
This paper presents open systems architecture-based software design for an online spindle health monitoring system. The software is implemented using the graphical programming language of LabVIEW, and presents the spindle health status in two types of

Smart Transducer Web Services Based on the IEEE 1451.0 Standard

May 1, 2007
Author(s)
Yuyin Song, Kang B. Lee
This paper describes the proposed Smart Transducer Web Services (STWS) developed at the National Institute of Standard and Technology (NIST) based on the proposed IEEE 1451.0 standard. The Smart Transducer Web Services were described in WSDL (Web Service

Spindle Health Diagnosis Based on Analytic Wavelet Enveloping

September 1, 2006
Author(s)
Li Zhang, Robert Gao, Kang B. Lee
A new diagnostic technique for identifying structural defects in spindles was developed, based on the analytic wavelet transform. The new technique extracts defect-induced impulses from the spindle vibration signal and constructs their envelopes in a

Optimization of Sensor Locations for Spindle Condition Monitoring

May 1, 2006
Author(s)
Li Zhang, Robert Gao, Kang B. Lee
This paper presents an approach to optimizing the location of vibration sensors on a spindle, based on the concept of Effective Independence (EfI). The study is aimed at investigating the effect of sensor placement on spindle vibration measurement, and its

A Wireless Environmental Monitoring System Based on the IEEE 1451.1 Standard

April 1, 2006
Author(s)
Kang B. Lee, Yuyin Song
This paper describes a wireless environmental monitoring system developed at the National Institute of Standards and Technology (NIST) based on the Institute of Electrical and Electronics Engineers (IEEE) 1451.1 standard using the Unified Modeling Language

An Implementation of the Proposed IEEE 1451.0 and 1451.5 Standards

February 7, 2006
Author(s)
Eugene Song, Kang B. Lee
This Paper describes an implementation of the proposed IEEE 1451.0 and 1451.5 Standards. The implemented systsem was developed based on the object-oriented framework of the IEEE 1451 standards using UML tools and Java programming language. The system

Open Standards for Homeland Security Sensor Networks

December 1, 2005
Author(s)
Kang B. Lee, Mark E. Reichardt
Sensors and networks are key components in building distributed sensor networks nation-wide for detecting weapons of mass destruction and monitoring and protecting critical infrastructure such as airports, bridges, buildings, railways, utility, and water

A Unifying Standard for Interfacing Transducers to Networks IEEE-1451.0

September 8, 2005
Author(s)
James Wiczer, Kang B. Lee
A committee of industry and government technology experts has completed a three-year effort to develop a set of specifications that consist of a unifying set of functions, communications protocols, a common set of commands, and electronic data sheet

Object-Oriented Application Framework for IEEE 1451.1 Standard

August 1, 2005
Author(s)
Eugene Song, Kang B. Lee
The National Institute of Standards and Technology (NIST) smart sensor project focuses on the development and support of the IEEE 1451 Smart Transducer Interface Standard for Sensors and Actuators. One of the main objectives of this project is to provide

Wavelet-Based Enveloping for Spindle Health Diagnosis

May 1, 2005
Author(s)
Li Zhang, Robert Gao, Kang B. Lee
A new method for identifying structural defect-induced vibration signals was developed based on the analytic wavelet transform. The advantage of this method is that it extracts defect-related impulse signal and constructs its envelope in a single step

A unifying Standard for Interfacing Transducers to Networks - IEEE-1451.0

James Wiczer, Kang B. Lee
A committee of industry and government technology experts has completed a three-year effort to develop a set of specifications that consist of a unifying set of functions, communications protocols, a common set of commands, and electronic data sheet

A Smart Transducer Interface Standard for Sensors and Actuators

January 1, 2004
Author(s)
Kang B. Lee
A set of common transducer interfaces has been defined in the family of IEEE 1451, standards for connecting sensors and actuators to microprocessors, control and field networks, and instrumentation systems. The standards also defined the Trans-ducer
