EL Highlights for August 2012
NIST Factory Equipment Network Testing (FENT) Demonstration is a Success
U.S. manufacturers need real-time production information to monitor and optimize the manufacturing activities in their factories. Currently, this information is typically collected manually from isolated proprietary equipment, a laborious process that takes time and introduces human error. Connecting this equipment to the factory network would make accurate production information immediately available, though widespread interconnection has been inhibited by the lack of common information models and methods to measure performance and conformance. In response to this need, NIST Engineering Laboratory staff developed a measurement science-based performance and conformance testing framework and test tools that measure the effectiveness of protocols and standards for collecting real-time production information from factory floor sensors and equipment. The NIST Factory Equipment Network Testing (FENT) Framework includes software modules and interfaces for testing and analyzing various sensor configurations and communication protocols, including Industrial Ethernet/IP and wireless IEEE 1451.5. EL researchers James Gilsinn, Kang Lee, Fred Proctor, and Eugene Song recently demonstrated this framework for wireless sensors in a distributed network. Wireless sensor networks based on the IEEE 1451.5 (WiFi wireless) sensor standard were placed in laboratories and shop environments across the NIST campus and sensor network performance tests were conducted using various network topology scenarios. Manufacturing equipment in the NIST Shops was instrumented with sensors to enable real-time machine condition monitoring. Sensor performance data was captured throughout the testing for both wired and wireless networks for analysis by the FENT modules. The new capability demonstrated by the NIST team shows the usefulness and flexibility of the FENT Framework for remote testing and analysis of sensor network performance in distributed environments, and will help reduce barriers to optimizing manufacturing activities within a factory. Andrew Mundy from EL System Administration (ELSA) collaborated on development of interfaces to the NIST wired and wireless networks to achieve these results.

NIST Roadmap Outlines a Research Plan to Reduce the Risk of Fire in Buildings and Communities
Fire researchers in the National Institute of Standards and Technology (NIST) Engineering Laboratory believe that the devastating annual toll of fire in buildings and communities can be significantly reduced over the next two decades. Now they have a plan that prioritizes and details the research and other work needed to enable that reduction. Crafted with input from fire service organizations, standards and building-code developers, equipment manufacturers, insurers and others, NIST's newly issued "strategic roadmap"* lays out a clear technological course for reducing the risk of fire in buildings and communities. It calls for attacking the nation's fire problem on three fronts:
- Reducing fire hazards in buildings,
- Advancing firefighter technologies, and
- Reducing the risk of fire in communities bordering forests and "wildlands."
Reflecting NIST's unique technical support role, the new roadmap sets targets for newmeasurement capabilities that underpin innovation in fire-risk-reducing technologies and best practices. These advanced capabilities are required to overcome technical hurdles that stand in the way of nascent or current technologies with the potential to deliver a wide range of fire safety benefits. These range from earlier fire detection and fire-safety improvements in the design and construction of buildings and communities, to better firefighting equipment and tactics, to more effective approaches to preventing and responding to "wildland-urban interface" fires, a rapidly growing national fire problem.
The roadmap sets short, medium and long-term goals for eliminating these gaps and accomplishing the overall objective of reducing the nation's fire burden by a third. The publication is available at www.nist.gov/manuscript-publication-search.cfm?pub_id=909653.

Additive Manufacturing Test Artifact Revealed
At the 23rd Annual Solid Freeform Fabrication Symposium held in Austin, TX on August 6-8, EL researchers Shawn Moylan and April Cooke unveiled a NIST-designed test artifact for additive manufacturing machines and processes. Shawn presented the paper "Proposal for a Standardized Test Artifact for Additive Manufacturing Machines and Processes," describing the test artifact and its carefully-designed features that indicate a variety of additive manufacturing (AM) system capabilities and performance. The artifact will both help potential users to better understand AM system capabilities, and also provide a common benchmark for AM equipment suppliers seeking to improve the performance of their products. The symposium was attended by approximately 150 people in the additive manufacturing community, including many members of the ASTM F42 committee on Additive Manufacturing Technologies. The test artifact is ultimately intended for standardization through ASTM F42, but a preliminary step is for U.S. companies and additive manufacturing experts to build the proposed test artifact on their systems and to offer feedback on the performance of their systems, as well as, improvements to the artifact. The test artifact along with supporting documentation and an inspection worksheet was sent to several companies and institutions, including Harvest Technologies, ExOne, Lawrence Livermore National Laboratory, General Electric Aviation, and the University of Texas at El Paso.

Smart Grid Workshop Identifies Technology and Measurement Priorities
The NIST Engineering Laboratory co-organized an invitational workshop with the Renewable and Sustainable Energy Institute (RASEI), in Boulder, Colorado, on August 13 & 14, 2012. RASEI is a joint project of the University of Colorado and the National Renewable Energy Laboratory (NREL). The purpose of the workshop was seek consensus on identification of technological and metrology impediments to the successful development and deployment of the emerging cyber-physical electric power grid, often referred to as the smart grid, and then to prioritize research needed to overcome these impediments. The workshop was co-chaired by leaders in the smart grid community: John McDonald, Director of Technical Strategy and Policy Development at General Electric Digital Energy, and Mark McGranaghan, Vice President of Power Delivery and Utilization at the Electric Power Research Institute. There were approximately 80 participants from industry, academia, and government laboratories, and an additional fifteen NIST and RASEI personnel. By design, NIST and RASEI personnel served primarily as observers, so that the workshop would be able to develop a strong imprimatur from industry. Exceptions to this rule were NIST Smart Grid Program Director and National Coordinator for Smart Grid Interoperability Dr. George Arnold, EL Director Dr. Shyam Sunder, RASEI Director Michael Knotek, and University of Colorado faculty member Kevin Doran, all of whom gave plenary talks. The NIST Smart Grid and Cyber-Physical Systems Program Office led the planning of the workshop, with assistance from the NIST Standards Coordination Office.
All workshop participants were assigned to one of four topical working groups: (i) integration of renewables onto the grid, (ii) integration of distributed generation and energy storage, (iii) energy efficiency, demand response, and load control, and (iv) efficiency, reliability, security, and stability of the grid. Within their respective areas, each working group addressed the questions of present status, aspirational goals, major technological and other challenges, and prioritization of research and measurement science needed for the smart grid.
Key outcomes from the workshop will be a technical report of the workshop's findings (Nov 2012), and a high-level opportunities document (Jan 2013) to help NIST and other organizations focus on the most important research challenges. Both are expected to be used by a broad range of industry planners and researchers in the smart grid arena.
