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.”

Dubai will stage its high-profile aerospace pageant next week against the backdrop of the Israel-Hamas war in Gaza that is pushing up demand for weapons while closing airspace and making flights longer and more expensive for some airlines.

By: Stephen Losey The Air Force has awarded a $499 million contract to L3 Technologies to modernize avionics for the service's Guard and Reserve C-130H Herculesfleet. In a June 6 release, L3 said it had received the Air Force's C-130H Avionics Modernization Program Increment 2 contract, to design, produce and certify a plan to upgrade the 176 Hercules aircraft belonging to the Air National Guard and Air Force Reserve. L3 said its upgrades will improve the Hercules' availability, reliability and sustainability, while lowering its costs to operate the transport aircraft. The aircraft will receive a commercial off-the-shelf avionics suite and L3 will provide training services, according to the release. The contractor will carry out the work at its facility in Waco, Texas. “L3 is committed to delivering innovative, cost-effective solutions to ensure mission readiness in support of the U.S. Air Force's modernization strategy,” L3 CEO and president Christopher Kubasik said in the release. “We are focused on providing an agile and low-risk approach to modernizing the Air Force's diverse fleet of C-130s, enabling these assets to operate well into the future.” The Air Force's C-130Hs are among the older transport aircraft in the fleet. In 2017, the most recent year for which data is available, the Air Force's 188 C-130Hs had an average age of 28 years. https://www.airforcetimes.com/news/your-air-force/2019/06/10/c-130hs-to-get-avionics-upgrade-in-half-billion-dollar-deal/

By: The Associated Press BEIJING — A study says Southeast Asian countries are cutting defense spending as a result of the economic crisis brought on by the coronavirus outbreak, potentially opening up room for China to further assert its claims in the region. Aristyo Rizka Darmawan, a maritime security expert at the University of Indonesia, writes that slashing defense spending is seen as a relatively easy way to cut costs when countries are facing pressure on their budgets. “Indonesia, for example, has announced it will slash its defense budget this year by nearly US$588 million. Thailand has likewise reduced its defense allocation by $555 million. Malaysia, Vietnam, and the Philippines all face similar pressure,” Darmawan wrote in the online journal of the Lowy Institute, an Australian think tank. “Less defense spending will invariably mean less patrols at sea.” China recently announced it will increase its defense spending by 6.6 percent in 2020, despite a major downturn in the country's economic growth due to the pandemic. The increase is the lowest in years, but will still allow China to expand its ability to enforce its territorial claims in the South China Sea and grow its military presence in the Western Pacific and Indian oceans. Another key priority is maintaining a credible threat against Taiwan, the self-governing island democracy that China considers its own territory, to be brought under its control by military force if necessary. China has maintained its presence in the South China Sea throughout the virus outbreak. Recent frictions include Chinese ships shadowing Malaysian mineral exploration operations and the sinking of a Vietnamese fishing boat by a Chinese maritime security vessel. However, China's foreign minister dismissed claims that the country is exploiting the coronavirus outbreak to expand its regional footprint, labeling such accusations as “sheer nonsense.” State Councilor and Foreign Minister Wang Yi told reporters at a news conference on Sunday that China is cooperating closely on anti-virus efforts with Southeast Asian countries, several of whom have overlapping territorial claims with China in the strategically vital waterway. While China has long been stepping up its presence in the region, Wang said other countries — likely meaning the United States and its allies — have been creating instability with military flights and sea patrols. “Their ill-intentioned and despicable moves are meant to sow discord between China and [Southeast Asian countries] and undermine the hard-won stability in the region,” Wang said. https://www.defensenews.com/global/asia-pacific/2020/05/26/downward-trend-southeast-asian-countries-cut-defense-spending/
