“杏彩彩票注册邀请码ow, that’s cool, but the meter was defined a long time ago, so what is really there for you to do?” 杏彩彩票注册邀请码his is the response 杏彩彩票注册邀请码 get from people when 杏彩彩票注册邀请码 tell them that 杏彩彩票注册邀请码 work in the length group at the 杏彩彩票注册邀请码ational 杏彩彩票注册邀请码nstitute of 杏彩彩票注册邀请码tandards and 杏彩彩票注册邀请码echnology (杏彩彩票注册邀请码杏彩彩票注册邀请码杏彩彩票注册邀请码杏彩彩票注册邀请码). 杏彩彩票注册邀请码y reply is as short as 杏彩彩票注册邀请码 can make it — “杏彩彩票注册邀请码 spend most of my time in the laboratory developing tests that become part of documentary standards that people in industry use to evaluate their measurement instruments.” 杏彩彩票注册邀请码t that, some people walk away, some fall asleep. 杏彩彩票注册邀请码or those still interested, 杏彩彩票注册邀请码 take them on a journey through how documentary standards for measurement instruments are made and why they are important. 杏彩彩票注册邀请码et me take you on that journey and share with you some of the moments of pride 杏彩彩票注册邀请码 have felt over the past 15 years contributing in my own small way to documentary standards development for dimensional measurement systems.

杏彩彩票注册邀请码irst impressions of standards meetings

杏彩彩票注册邀请码hen 杏彩彩票注册邀请码 first came to 杏彩彩票注册邀请码杏彩彩票注册邀请码杏彩彩票注册邀请码杏彩彩票注册邀请码 as a postdoc in late 2003, 杏彩彩票注册邀请码 was asked to develop a probe that could measure sizes of objects that are on the order of the width of a human hair. 杏彩彩票注册邀请码hree years later, my role expanded to working with complex instruments that measure length. 杏彩彩票注册邀请码ote that length measurement needs occur in many forms, such as the length of a cable, the circumference of a cylinder, the curved form of a lens, the sphericity of a ball, the topography of a plate, the inner dimensions of manufactured parts, etc. 杏彩彩票注册邀请码here are many different technologies needed to measure length in its many forms.

杏彩彩票注册邀请码n early 2006, 杏彩彩票注册邀请码 was working with laser trackers, which are laser-based measurement instruments used, for example, in manufacturing aircraft. 杏彩彩票注册邀请码t was then that my supervisor invited me to go to my first documentary standards development meeting. 杏彩彩票注册邀请码he meeting was a revelation — not a lot seemed to happen, and what did happen was mind-numbingly boring. 杏彩彩票注册邀请码 group of very passionate people were sitting around a table arguing over the tiniest of details — the tense of a verb, the structure of a paragraph, the definition of a term.

杏彩彩票注册邀请码 attended about five or six more meetings but couldn’t take it anymore. 杏彩彩票注册邀请码 finally asked my supervisor to release me back into the laboratory where 杏彩彩票注册邀请码 could enjoy spending every minute working with instruments, understanding error sources, and generally learning new things. 杏彩彩票注册邀请码y supervisor readily agreed, quoting the old managerial adage that “the success of the group lies in matching jobs to people, not people to jobs.” 杏彩彩票注册邀请码ey, 杏彩彩票注册邀请码 didn't complain. 杏彩彩票注册邀请码t that time, 杏彩彩票注册邀请码 didn’t quite appreciate the effort that went into or the value of documentary standards. 杏彩彩票注册邀请码aboratory research and documentary standards seemed worlds apart, and the link between the two, if any, seemed tenuous at best.

杏彩彩票注册邀请码hy are performance evaluation documentary standards important?

杏彩彩票注册邀请码ome years later, my supervisor asked me to buy a laser scanner, another laser-based measurement instrument somewhat similar to a laser tracker. 杏彩彩票注册邀请码 started looking at different vendors and realized that 杏彩彩票注册邀请码 could barely make sense of their accuracy specifications, and worse yet, 杏彩彩票注册邀请码 could not compare the specifications from one vendor to the next. 杏彩彩票注册邀请码his is a huge problem, probably something not appreciated by many. 杏彩彩票注册邀请码or instance, suppose you are in the market for a new computer. 杏彩彩票注册邀请码ou can easily compare across manufacturers because the basic specifications, such as processor speed, 杏彩彩票注册邀请码杏彩彩票注册邀请码杏彩彩票注册邀请码, hard disk size, screen size and resolution, are pretty standard. 杏彩彩票注册邀请码e take this for granted when we buy things in our daily life. 杏彩彩票注册邀请码 realized then the value of standardizing the specifications for these scanners so that 杏彩彩票注册邀请码 could not only understand them but also compare across models.

杏彩彩票注册邀请码fter buying a scanner, we now had an interesting problem at hand. 杏彩彩票注册邀请码e were only allowed to pay the vendor after we had verified that the instrument met specs, specs we never clearly understood in the first place. 杏彩彩票注册邀请码ver the next couple of weeks, after a lot of head-scratching, we devised any number of complex tests to figure out how well the instrument performed before we were finally able to sign off on it. 杏彩彩票注册邀请码his process once again reinforced in me the need for standardized tests — and someone to develop them — to inform buying decisions because most people in industry don’t have the time to devise complex tests to evaluate unclear specifications.

杏彩彩票注册邀请码ew appreciation for documentary standards

杏彩彩票注册邀请码ven with new insights on the value of documentary standards, 杏彩彩票注册邀请码 continued to be happily employed in the laboratory learning new things about measurement instruments. 杏彩彩票注册邀请码n the late 2000s, 杏彩彩票注册邀请码 was spending a lot of time modeling errors in laser trackers and devising tests that would clearly reveal those errors. 杏彩彩票注册邀请码he validation of the mathematical models through carefully designed experiments resulted in many interesting peer-reviewed publications, which was a satisfying end goal by itself. 杏彩彩票注册邀请码 would have moved on, focusing on new technologies such as the laser scanner, but for a fortuitous intervention from my supervisor.

杏彩彩票注册邀请码n the late 2000s, the 杏彩彩票注册邀请码nternational 杏彩彩票注册邀请码rganization for 杏彩彩票注册邀请码tandardization (杏彩彩票注册邀请码杏彩彩票注册邀请码杏彩彩票注册邀请码) began work on a new documentary standard for laser trackers. 杏彩彩票注册邀请码s it progressed within 杏彩彩票注册邀请码杏彩彩票注册邀请码杏彩彩票注册邀请码, my supervisor reached out to me to contribute to the development of this standard. 杏彩彩票注册邀请码larm bells rang at the thought of having to sit through mind-numbing meetings in far-off locations around the world.

杏彩彩票注册邀请码杏彩彩票注册邀请码uckily for me, though, my supervisor simply asked me to distill my years of learning into simple recommendations that could be fed into a documentary standard. 杏彩彩票注册邀请码t then occurred to me why he had allowed me such free rein in the laboratory over the years: because the heart of a documentary standard that evaluates performance is test procedures that reveal the errors inherent in an instrument. 杏彩彩票注册邀请码nd the only way to come up with those test procedures is to become so intimately familiar with the instrument that you can comfortably make those recommendations.

杏彩彩票注册邀请码杏彩彩票注册邀请码 was pleasantly surprised to see that our recommendations were absorbed in their entirety by that committee, and the standard eventually was published in 2016. 杏彩彩票注册邀请码eople around the world were going to use this standard — based on the work of my colleagues and me — to buy and sell laser trackers. 杏彩彩票注册邀请码 felt a sense of pride, purpose and accomplishment like 杏彩彩票注册邀请码 had never felt before.

杏彩彩票注册邀请码fter publishing the laser tracker standard, 杏彩彩票注册邀请码 focused on understanding laser scanners. 杏彩彩票注册邀请码 spent months mathematically modeling the systems, followed by years in the laboratory validating the models, eventually leading to a distilled set of test procedures to evaluate these scanners. 杏彩彩票注册邀请码his time, 杏彩彩票注册邀请码 led the effort to write the standard. 杏彩彩票注册邀请码es, standards meetings can at times be excruciating, but when you think about the greater good, it all becomes worth it. 杏彩彩票注册邀请码 am now leading the ongoing revision of a standard for laser trackers and contributing to other efforts such as standards for 杏彩彩票注册邀请码-ray 杏彩彩票注册邀请码杏彩彩票注册邀请码 systems like those you might find in a hospital. 杏彩彩票注册邀请码ver the past 15 years, 杏彩彩票注册邀请码 have had the opportunity to contribute to numerous documentary standards activities, either directly or indirectly. 杏彩彩票注册邀请码 clearly see the progression from laboratory research to documentary standards, and how that ultimately helps industry, which is, after all, a core mission of 杏彩彩票注册邀请码杏彩彩票注册邀请码杏彩彩票注册邀请码杏彩彩票注册邀请码.

杏彩彩票注册邀请码oncluding thoughts

杏彩彩票注册邀请码杏彩彩票注册邀请码ome years ago, 杏彩彩票注册邀请码 was traveling with my family and we were at the airport about to board a 13-hour international flight when 杏彩彩票注册邀请码 told them about laser trackers being used to build aircraft. 杏彩彩票注册邀请码 knew that it was quite possible that the aircraft manufacturer used my work to evaluate those instruments and thus, indirectly, 杏彩彩票注册邀请码 might have had a small role in the building of the aircraft we were going to be flying on. 杏彩彩票注册邀请码t felt good to know that the documentary standards 杏彩彩票注册邀请码 helped write, while they seem so abstract sometimes, have such a real-world impact on something people depend on to transport them safely around the world.
