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.”

Boeing Awarded $1.5B Contract for 28 Kuwait Super Hornets
By: Ben Werner Boeing was awarded a $1.5 billion contract to build 28 F/A-18E/F Super Hornets for the Kuwait Air Force, according to a Wednesday Pentagon contract announcement. Kuwait is buying 22 of the single-seat “E” variant and six of the two-seat “F” variant Super Hornet. The deal has been in the works since late 2016 when U.S. State Department notified Congress about Kuwait's intent to purchase Super Hornets. On March 30, Boeing was awarded a $1.16 billion contract to research, development and testing for the Kuwait deal. The deal Kuwait finalized Wednesday is a scaled-down version of the initial purchase announced in 2016 which involved 40 aircraft. At the time, the deal was considered significant by industry analysts and U.S. government officials because it would keep Boeing's Super Hornet production line operational. Since the 2016 announcement, Boeing has courted several potential international Super Hornet customers, including Finland, India, Switzerland and Germany. The U.S. Navy has announced it plans to purchase 116 additional Super Hornets — bringing its fleet up to 480 aircraft. When the Navy orders are added to possible international sales, the St. Louis-based production line could remain running for more than a decade. The following is the complete June 27, 2018 contract award. The Boeing Co., St. Louis, Missouri, is awarded a $1,504,995,240 fixed-price-incentive-firm contract that provides for the production and delivery of 22 F/A-18E and six F/A-18F Super Hornets in support of the government of Kuwait. Work will be performed in El Segundo, California (41.4 percent); Hazelwood, Missouri (28.2 percent); Fort Worth, Texas (4.7 percent); Santa Clarita, California (4 percent); Bloomington, Minnesota (3.3 percent); Greenlawn, New York (2.8 percent); Endicott, New York (2.3 percent); Santa Ana, California (1.9 percent); Clearwater, Florida (1.5 percent); Clifton, New Jersey (1.3 percent); Mesa, Arizona (1.3 percent); Torrance, California (1.2 percent); Ontario, Canada (1 percent); Vandalia, Ohio (0.9 percent); Kalamazoo, Michigan (0.8 percent); Fort Walton Beach, Florida (0.8 percent); East Aurora, New York (0.7 percent); and various locations outside the continental U.S. (2.1 percent), and is expected to be completed in January 2021. Foreign military sales funds in the amount of $1,504,995,240 will be obligated at time of award, none of which will expire at the end of the current fiscal year. The Naval Air Systems Command, Patuxent River, Maryland, is the contracting activity (N00019-18-C-1060). https://news.usni.org/2018/06/28/kuwait-finalizes-contract-for-28-super-hornets

La Fabrique Défense s’ouvre à l’Europe
La Fabrique Défense se veut le « rendez-vous de référence de l'ensemble des acteurs de l'écosystème de la défense », a expliqué la ministre des Armées Florence Parly lors de sa visite le 28 janvier en ouverture du salon à Paris. Il constitue un événement visant à participer au développement d'une culture européenne en matière de défense, notamment auprès des jeunes Européens. Outre le salon en lui-même, l'édition 2021-2022 a permis d'organiser une centaine d'événements en France et dans 20 autres pays européens autour de la question. A cette occasion, de nombreux acteurs (institutionnels, universités, associations, entreprises, think tanks, etc.) ont été associés pour organiser ces rendez-vous, autour de 136 stands répartis en 13 espaces thématiques. Outre les stands, un programme riche de tables rondes et de témoignages professionnels a permis aux visiteurs de découvrir les grands enjeux de la défense. Des espaces animations avec notamment des Serious Games (wargames, simulateurs de vol, etc.), et des démonstrations extérieures (drones) étaient également proposées. Au moment où la filière recrute, le GIFAS était présent, aux côtés de l'armée de l'Air et de l'Espace et des industriels du secteur. Cet espace avait vocation à présenter au public la contribution de l'industrie aéronautique et spatiale à la Défense et ses nombreuses opportunités de métiers et d'emplois.
