Innovation and Competitiveness in Artificial Intelligence

The International Trade Administration (ITA) of the U.S. Department of Commerce (DOC) is requesting public comments to gain insights on the current global artificial intelligence (AI) market. Responses will provide clarity about stakeholder concerns regarding international AI policies, regulations, and other measures which may impact U.S. exports of AI technologies. Additionally, the request for information (RFI) includes inquiries related to AI standards development. ~~ANSI encourages relevant stakeholders to respond by ITA’s deadline of October 17, 2022.~~

Optical Frequency Comb

Compact Chips Advance Precision Timing for Communications, Navigation and Other Applications

Abstract: Numerous modern technologies are reliant on the low-phase noise and exquisite timing stability of microwave signals. Substantial progress has been made in the field of microwave photonics, whereby low-noise microwave signals are generated by the down-conversion of ultrastable optical references using a frequency comb^1,2,3. Such systems, however, are constructed with bulk or fibre optics and are difficult to further reduce in size and power consumption. In this work we address this challenge by leveraging advances in integrated photonics to demonstrate low-noise microwave generation via two-point optical frequency division^4,5. Narrow-linewidth self-injection-locked integrated lasers^6,7 are stabilized to a miniature Fabry–Pérot cavity⁸, and the frequency gap between the lasers is divided with an efficient dark soliton frequency comb⁹. The stabilized output of the microcomb is photodetected to produce a microwave signal at 20 GHz with phase noise of −96 dBc Hz⁻¹ at 100 Hz offset frequency that decreases to −135 dBc Hz⁻¹ at 10 kHz offset—values that are unprecedented for an integrated photonic system. All photonic components can be heterogeneously integrated on a single chip, providing a significant advance for the application of photonics to high-precision navigation, communication and timing systems.

If I wish to explain it to him who asks, I do not know.”

“Time flies like an arrow; fruit flies like a banana.” — Groucho Marx

“Time is a great healer, but a terrible beautician.” — Unknown

“Time and tide wait for no man, but time always stands still for a woman of 30.” — Robert Frost

“Time is what we want most, but what we use worst.” — William Penn

“Time is the best teacher; unfortunately, it kills all its students.” — Robin Williams

“Inside every older person is a younger person wondering what happened.” — Jennifer Yane

“Age is an issue of mind over matter. If you don’t mind, it doesn’t matter.” — Mark Twain

“They say time is a great teacher, but unfortunately it kills all its pupils.” — Louis Hector Berlioz

“Middle age is when you’re sitting at home on a Saturday night and the telephone rings, and you hope it isn’t for you.” — Ogden Nash

The Intersection of Design and Engineering

Technical Barriers to Trade

World According to Marco Polo

We track action in international administrative procedures that affect the safety and sustainability agenda of the education facility industry. From time to time we find product purchasing contracts that contain “boilerplate” requiring conformity to applicable regulations found in the Agreement on Technical Barriers to Trade (TBT). Common examples are found in contracts for the acquisition of information technology and specialty laboratory equipment.

The World Trade Organization TBT Agreement obliges all Parties to maintain an inquiry point that is able to answer questions from interested parties and other WTO Members regarding technical regulations, standards developed by government bodies, and conformity assessment procedures, as well as provide relevant documents. The TBT Agreement also requires that WTO Members notify the WTO of proposed technical regulations and conformity assessment procedures so interested parties can become acquainted with them and have an opportunity to submit written comments.

Technical Barriers to Trade Information Management System

The inquiry point and notification authority for the United States is operated by the National Institute of Standards and Technology an agency within the U.S. Department of Commerce. We provide a link here for the convenience of faculty, specifiers and purchasing professionals.

Blockchain Technology

Distributed Ledger Technology

The U.S. Commerce Department’s National Institute of Standards and Technology (NIST) issued a draft report — and a commenting opportunity the repport — that details a high-level technical overview of blockchain technology, its architecture, and how it works as the foundation of modern cryptocurrencies. NIST requested feedback from the public and private sectors, national and international, for the final publication. The document, Draft NIST Interagency Report (NISTIR) 8202: Blockchain Technology Overview, provided an in-depth look at the technologies that compromise blockchain systems and breaks down how blockchains can best be utilized, and how blockchain technology can be an asset to a business and its products.

“We want to help people understand how blockchains work so that they can appropriately and usefully apply them to technology problems,” said Dylan Yaga, a NIST computer scientist and co-author of the report. “It’s an introduction to the things you should understand and think about if you want to use blockchain.”

The report appears to have integrated public comment and now a landing page for NIST work in this area — as well as contact information for project leaders — is linked below

Federal Agency Conformity Assessment

NIST Headquarters / Gaithersburg, Maryland

The National Institute of Standards and Technology requests comments on proposed revisions to regulations updating policy guidance on Federal agency use of conformity assessment that reflects advancement in conformity assessment concepts, and the evolution in Federal agency strategies and coordination in using and relying on conformity assessment.

The provisions are solely intended to be used as guidance for agencies in their use and reliance on conformity assessment to meet agency requirements and do not preempt the agency authority and responsibility to make decisions authorized by statute or required in establishing regulatory, procurement, or programmatic activities.
