  DARPA wants to connect human brains and machines

  By: Daniel Cebul WASHINGTON ― As unmanned platforms, cyber systems and human-machine partnering become more prevalent in 21st century war fighting, the effectiveness of combat units will be determined by how quickly information can be processed and transmitted between air-breathers and machines. To achieve the high levels of brain-system communication that will be required on future battlefields, the Defense Advanced Research Projects Agency has launched a new program to develop a noninvasive neural interface that will connect soldiers with technology. The goal of the Next-Generation Nonsurgical Neurotechnology (N³) program is to “pursue a path to a safe, portable neural interface system capable of reading from and writing to multiple points in the brain at once,” according to Dr. Al Emondi, a program manager in DARPA's Biological Technologies Office. “We're asking multidisciplinary teams of researchers to construct approaches that enable precise interaction with very small areas of the brain, without sacrificing signal resolution or introducing unacceptable latency into the N3 system.” Although technologies that allow for high-quality brain system communications exist today, these invasive techniques are not a practical solution for ubiquitous man-machine communication. Before soldiers can communicate with their R2-D2 units, DARPA scientists must overcome several significant scientific and engineering challenges. The most significant challenge, according to a DARPA press release, will be overcoming the physics of scattering and weakening of signals as they pass through skin, skull and brain tissue. If this initial challenge is surmounted, the focus of the program will shift to developing algorithms for encoding and decoding neural signals, evaluating system safety through animal testing and ultimately asking human volunteers to test the technology. While communication neurotechnology has a stronger foothold in science fiction than reality, Emondi believes devoting resources to the enterprise will spur breakthroughs. “Smart systems will significantly impact how our troops operate in the future, and now is the time to be thinking about what human-machine teaming will actually look like and how it might be accomplished,” he said. “If we put the best scientists on this problem, we will disrupt current neural interface approaches and open the door to practical, high-performance interfaces.” DARPA wants the four-year project to conclude with a demonstration of a bidirectional system being used to interface human-machine interactions with unmanned platforms, active cyber defense systems or other Department of Defense equipment. Recognizing the potentially wide ethical, legal and social implications of such neurotechnology, DARPA is also asking independent legal and ethical experts to advise the program as N³ technologies mature. https://www.c4isrnet.com/it-networks/2018/03/19/darpa-wants-to-connect-human-brains-and-machines

  Army validates design for future helicopter engine, remains on track despite COVID

  By: Jen Judson WASHINGTON — The Army has validated its design for its future helicopter engine, and the program remains on schedule to deliver the first engine for testing in the fourth quarter of fiscal 2021, according to service officials in charge of the effort. The Improved Engine Turbine Program (ITEP) has seen a long — and often delayed — journey as the service wrestled with funding and development strategies for several years. ITEP will replace current engines in both UH-60 Black Hawk utility helicopters and AH-64 Apache attack helicopters Since awarding a contract to General Electric Aviation in February 2019, the program has pushed forward on schedule, despite a protest from a competing team comprised of Honeywell and Pratt & Whitney, which paused work for roughly three months. And, while the Coronavirus pandemic caused some anxiety among Army officials trying to keep the program on track, those in charge were able to complete the critical design review, conducted 100 percent virtually, according to Army spokesman David Hylton. The ITEP Critical Design Review (CDR) was a multi-month process that consisted of three phases, Hylton told Defense News in a written statement. The engine control system component CDR was completed on June 5, followed by the software CDR on July 17 and the engine systems CDR on July 24, he said. The Army and GE are making “tremendous efforts to keep COVID-19 impacts from delaying the program,” Hylton wrote. GE is now working toward a test readiness review ahead of the first engine test. “We are full steam ahead in terms of understanding where we need to go next with respect to the design, Col. Gregory Fortier, who is in charge of the program office for the Army's Future Attack Reconnaissance Aircraft, said during a media briefing last month. The Army has “no reason to believe we will not fly” in fiscal 2023, he said. According to FY21 Army budget request justification documents, the service plans to fly an aircraft with an ITEP engine installed in the first quarter of FY23 followed by a low-rate initial production decision in the fourth quarter of FY24. A full-rate production decision is expected in FY26. https://www.defensenews.com/land/2020/08/12/army-validates-design-for-future-helicopter-engine-remains-on-track-despite-covid/
