    Battelle To Explore Artificial Intelligence, Neural Interfaces with DARPA Award

    COLUMBUS, Ohio--(BUSINESS WIRE)--Battelle is combining years of brain-computer interface (BCI) projects, such as NeuroLife®, with its expertise in machine learning and artificial intelligence under a new award from the federal government's forward-thinking government agency, the Defense Advanced Research Projects Agency (DARPA). The award is part of DARPA's Artificial Intelligence Exploration program called Intelligent Neural Interfaces. Using terabytes of neural data gathered in the past five years during NeuroLife sessions, Battelle Senior Data Scientist David Friedenberg and his team will build new decoding algorithms to make neural interfaces more robust over long periods of time. The BCI systems typically rely on a decoder that monitors brain activity and then translates it into actions—in the case of NeuroLife, those signals are sent to a special sleeve that uses electrodes to stimulate muscles to evoke hand movement. However, the decoders require significant and time-consuming calibration to learn the mapping between the brain data and the user's intended action. In June, the Battelle team began work on a $1 million, 18-month project that will try to solve longstanding problems with decoder optimization and maintenance while improving accuracy and robustness. To accomplish this goal, Battelle will develop a hybrid approach for stable long-term neural decoding using end-to-end deep neural network decoders to learn optimal features from the raw electrode recordings. In addition, using third-wave AI approaches, Battelle will develop models that account for changing context and continuously adapt accordingly. This allows for adjusting both the features and the decoder on-the-fly during normal system use to counteract non-stationarities and instabilities in the signal without requiring the user to intervene and recalibrate the system. The next evolution of BCIs will occur as the systems move from the lab into the real lives of users. “We want these systems to require less training and be more robust to interruptions and interference,” said Friedenberg. “We want to develop optimal decoders that automatically and continuously adapt to each individual and the BCI they're using.” About Battelle Every day, the people of Battelle apply science and technology to solving what matters most. At major technology centers and national laboratories around the world, Battelle conducts research and development, designs and manufactures products, and delivers critical services for government and commercial customers. Headquartered in Columbus, Ohio since its founding in 1929, Battelle makes the world better by commercializing technology, giving back to our communities, and supporting science, technology, engineering and mathematics (STEM) education.

    Opinion: Why The Future Will Not Be Virtual

    Steven Grundman The COVID-19 pandemic has accustomed us to living in the virtual world and hearing speculation about the ways in which our actual lives may never resume as before. Microsoft founder Bill Gates recently said he believes “over 50% of business travel and over 30% of days in the office will go away.” Explaining why the pandemic-induced surge in virtual house calls is likely to endure, Harvard's Dr. Thomas Delbanco concedes: “There are times when doctors, nurses or therapists really need to see you—no question about it. But there are also times when they really don't.” It was against the backdrop of such head-turning New Year's predictions that I spent the holidays reading about the Cold War and forming a nostalgic rebuttal to those prophesies of Zoom. At the start of my professional life, I led a surveillance platoon of the U.S. 1st Armored Division (1st AD), which was deployed to defend the “Frontier of Freedom” in the towns surrounding Nuremberg, West Germany. So it was that after cracking open Fulda Gap: Battlefield of the Cold War Alliances, I quickly thumbed forward to Chapter 7, “A Personal Perspective from Platoon Leader to Army Group” by Gen. (ret.) Crosbie Saint, who had commanded the 1st AD during my service in it. Saint's reflections transported me back to 1984 and the pastoral beauty of the Bavarian Oberpfalz, where we were actively preparing to fight a third world war. Prominent among the preparations Saint recounts was the terrain walk, a compulsory practice of every officer leading a maneuver unit regularly to traverse the ground where his troops would deploy, battle book in hand, mastering the contours of the landscape and envisioning his squads' movements in the General Defense Plan. Saint writes ardently about how “repetitive terrain walks at multiple command levels to analyze and become expert in exploiting the terrain for tactical purposes” gave the U.S. a decisive advantage over the vast armies of the Warsaw Pact. The still-clear memory of then-Lt. Grundman's own terrain walks along the monikered kill zones in my battle book—The Kemnath Bowl, Erbendorf Fire Trap, et al.—prompted me to wonder if the marvels of a virtual reality simulation would leave as indelible a mark. I doubt it. While the adoption of videoconferencing for commodity conversation is no doubt here to stay, the premium work of enterprise leadership must remain incarnate. Just as the experience of looking out from a ridgeline engages all the senses, strategic vision flows from an intuitive integration of time and space that no telemediation can fully activate. Beyond the battlefield lay other terrain walks affirming my conviction. In April 1993, just three weeks on the job as chief executive of an IBM teetering on insolvency, Lou Gerstner launched Operation Bear Hug, which directed each of the company's 250 most senior executives to visit at least five key customers over the following three months to learn why IBM had lost their trust. Years later, Gerstner wrote that Bear Hug made manifest what came to be the motive force of IBM's acclaimed transformation: “[W]e were going to build a company from the outside in and . . . the customer was going to drive everything we did in the company.” Gerstner invested this practice of deep listening to customers with the same strategic importance Saint attributed to a lieutenant's intimacy with the sight lines of his firing positions. Operation Bear Hug was a terrain walk. One of the trade secrets of my career as a business consultant to the aerospace industry is never to pass up an invitation to take a plant tour. No matter how near it is to your next flight's departure, when asked “Wanna see the shop?” the right answer is always “Of course.” When, a decade ago, I toured SpaceX's Hawthorne, California, headquarters and observed Elon Musk sitting at his desk among the busy cubicles of 30-something engineers gutting out their work in T-shirts, I instantly understood how the company's garage-shop culture could revolutionize the staid business of space launch. Years earlier, the clinical attention to workers' safety I saw at the bustling CFM56 jet engine plant in Villaroche, France, told me more about the success of the GE-Safran joint venture than even its impressive financials. So, too, did I need actually to feel the cavernous quietude in an antique defense factory to appreciate the true meaning of the sunk-cost fallacy. The aerospace plant tour is often a terrain walk. To all you leaders who, like me, find the progressively virtual world unsettling (and with apologies to a certain light lager's ad campaign), I say, “Find your terrain walk.” Once we again are free to move about, go physically to the crucible of what creates value for your enterprise and open your senses. Only from that vantage will you see truly into its future.

    Hypersonics by the dozens: US industry faces manufacturing challenge

    By: Jen Judson HUNTSVILLE, Ala. —The U.S. military is a few years from launching offensive hypersonic weapons that are currently under development. But building those initial missiles is one thing — manufacturing the weapons in multitude is another issue entirely. “I would say we really need to understand, again, how can we produce precision hardware at scale,” Michael Griffin, the Pentagon's undersecretary of defense for research and engineering, told a group of reporters Aug. 7 at the Space and Missile Defense Symposium in Huntsville, Alabama. “If we talk about ballistic missile defense or hypersonic offense and we talk about proliferating architectures, we need any dozens, many hundreds, maybe thousands of assets,” he added. “This takes us back to the Cold War where at one point we had 30,000 nuclear warheads and missiles to launch them. We haven't produced at that kind of scale since the wall came down.” As hypersonic missiles become a reality, industry is going to have to relearn how to effectively, efficiently and economically produce them, Griffin said. While industry has developed warheads, glide bodies and other components, there is no industrial base equipped to manufacture hypersonic weapons. Things are moving in the right direction when it comes to bringing industry up to speed and preparing for larger-scale manufacturing of missiles, Griffin said. But building these systems is challenging because, for example, hypersonics require a greater degree of thermal protection than what has been required of other weapons in the past, he noted. Building hypersonics is no longer a technical issue or a matter of understanding physics, but rather an issue of understanding the industrial engineering required to produce a larger number. “I'm not sure how much help the government can be there,” he said. “Mass production is not what we do. ... That is going to be an industry problem.” The Army is just weeks away from awarding a contract to a company that will work with the federally funded laboratory that developed a hypersonic glide body to develop manufacturing plans and strategies. Other companies will have a turn as well. The effort is spearheaded by the service's Rapid Capabilities and Critical Technologies Office. Griffin stressed that the weapons manufacturing process needs to be affordable. “Our adversaries have clearly found ways to make them affordable. China has these things now by the thousands. What do we do to learn, once again, how to produce sophisticated things at scale and affordably?” he said. China is able to field new systems every few years, Griffin noted, while the U.S. takes a decade or more to get through a cumbersome acquisition process. “It don't believe that the issues facing the United States aerospace and defense establishment are issues of specific technologies,” he said. “I believe that over the last 30 years ... we've become lost in our processes.” https://www.defensenews.com/digital-show-dailies/smd/2019/08/08/hypersonics-by-the-dozens-us-industry-faces-manufacturing-challenge/
