  U.S. arms makers and medical device firms team up to make ventilators

  WASHINGTON (Reuters) - U.S. weapons makers have teamed up with medical device companies to increase the supply of ventilators that can be used to combat the coronavirus pandemic, people working on the project said. The two groups do not regularly partner on projects, but when a defense industry consultant with an engineering background realized weapons makers could help solve supply-chain problems within the U.S. ventilator industry, the creation of Vent Connect was set in motion and is set to be announced on Monday, the people said. The idea gathered momentum when industry associations like the Aerospace Industries Association, which represents plane makers and defense contractors including Lockheed Martin Corp (LMT.N) and General Dynamics Corp (GD.N), teamed up with AdvaMed, the Advanced Medical Technology Association, whose members include vent manufacturers. A handful of ventilator makers including ResMed Inc (RMD.N), and Zoll, an Asahi Kasei Corp (3407.T) company, post requests in the ventilator parts marketplace to a group of 60 weapons and airplane makers to help meet surging demand for the life-saving machines, an AdvaMed representative said. Working since March to cut through challenges as varied as how to handle intellectual property, confidentiality issues, cybersecurity and logistics, the two associations created the marketplace that is now serving as a new avenue for the ventilator supply chain. The defense companies involved in the project did not want their names published because they did not want to appear to seek credit for their efforts. At its outset, the task was gargantuan. One ventilator maker, Medtronic (MDT.N), released a parts list with over 1,500 items to see if there was any crossover with the defense supply chain, two of the people said. Alphabet Inc's Google (GOOGL.O) was brought in to help set up a website so that the companies could better coordinate online. The two industries share some common equipment. For example, fighter jets use pressure sensors to regulate oxygen to their face masks, which are also a key element in a ventilator to ensure that the rhythm of a patient's breathing pattern is monitored and maintained for the person's comfort. The efforts to try to stem the ventilator shortage are being worked on by the U.S. Army as well. In mid-April, Army Secretary Ryan McCarthy offered an investment of $100,000 to innovators who could come up with a “rapid ventilator production system to support field hospitals that are still requiring critical infrastructure.” https://www.reuters.com/article/us-health-coronavirus-industry/u-s-arms-makers-and-medical-device-firms-team-up-to-make-ventilators-idUSKBN22G12C

  Le porte-avions «Charles-de-Gaulle» reprend la mer comme neuf

  Nicolas Berrod Après deux années de rénovation, le « Charles-de-Gaulle », à nouveau opérationnel, s'apprête à reprendre la mer. Nous avons pu passer 48 heures à bord, au côté de l'équipage, actuellement en pleine phase d'entraînement. « Wave off ! » Le cri de l'officier résonne sur le pont d'envol pour signifier à tout le monde de... « dégager ». Bienvenue à bord du « Charles-de-Gaulle », le seul porte-avions de la marine française, qui vient de subir un lifting intégral d'une durée de deux ans, pour un coût total de 1,3Mds €. Avant de repartir en mission dans quelques mois, ce mastodonte de 42 000 t pour 261 m de long poursuit ses entraînements au large de Toulon, son port d'attache. « On était orphelins, le Charles-de-Gaulle nous a manqué », sourit Christophe, capitaine de frégate et chef des pilotes. Avec ses collègues, ils ont eu beau s'être entraînés sur piste classique et sur un porte-avions américain le temps de la rénovation, rien ne vaut à leurs yeux le prestige du bateau français, en service depuis 2001. Le « Charles-de-Gaulle » aura un successeur, a assuré Emmanuel Macron, lorsqu'il sera mis hors service vers 2040. Coût estimé : minimum 3 Mds€. Et durée de la construction : 15 ans... au moins ! Chiens jaunes Alors, en attendant, la France compte sur son unique porte-avions, véritable village flottant de 2000 habitants - un équipage de 17 à 55 ans, dont 140 officiers de pont, 300 techniciens, 33 cuisiniers, 2 boulangers, 17 % de femmes au total. Après 18 mois passés à la cale, il faut le remettre en service. D'où, en cette fin d'automne, un entraînement intensif en Méditerranée, à quelques dizaines de kilomètres des côtes françaises. Entre quatre et vingt Rafales (NDLR : avions de combat) sont catapultés trois fois par jour, décollant sur une piste d'à peine quelques dizaines de mètres. Au signal des « chiens jaunes », ces officiers de pont reconnaissables à leur gilet coloré, les avions atteignent en quelques secondes les 200 km/h. Ce lundi-là, une poignée de jeunes pilotes - entre 22 et 26 ans - effectuent leur baptême de vol sur le « Charles-de-Gaulle ». Pour pouvoir manœuvrer sur un porte-avions, il leur faut avoir un minimum de 100 heures de vol sur Rafale. « On porte une attention toute particulière à ces jeunes », glisse, l'œil rivé à la piste, Jean-Philippe, chef des « chiens jaunes ». À l'issue de leur vol - ce jour-là dans un ciel dégagé -, ces pilotes doivent accrocher l'un des trois brins d'arrêt situés sur la piste pour apponter. Ces épais c'bles qui stoppent le Rafale d'un coup sont indispensables sur une piste aussi courte. « C'est comme si on pilait sur autoroute », glisse un officier, qui scrute à l'horizon les premiers avions sur le retour. Paradoxalement, au moment de toucher le pont à 250 km/h, les pilotes doivent remettre les gaz à fond. Car, s'ils ratent les brins, il faut pouvoir redécoller à temps ! « On appelle ça un bolter, c'est un peu un bizutage pour les nouveaux », sourit l'expérimenté capitaine Christophe, 2000 heures de vol sur Rafale derrière lui.

  DARPA: Five Teams of Researchers Will Help DARPA Detect Undersea Activity by Analyzing Behaviors of Marine Organisms

  Goliath grouper, black sea bass, and snapping shrimp, along with bioluminescent plankton and other microorganisms, are set to be the unlikely heroes of DARPA's Persistent Aquatic Living Sensors (PALS) program. Five teams of researchers are developing new types of sensor systems that detect and record the behaviors of these marine organisms and interpret them to identify, characterize, and report on the presence of manned and unmanned underwater vehicles operating in strategic waters. This new, bio-centric PALS technology will augment the Department of Defense's existing, hardware-based maritime monitoring systems and greatly extend the range, sensitivity, and lifetime of the military's undersea surveillance capabilities. DARPA first announced the PALS program in February 2018 with the goal of incorporating biology into new solutions for monitoring adversary movements across the seemingly endless spaces of the world's oceans and seas. Ubiquitous, self-replicating, self-sustaining sea life is adaptable and highly responsive to its environment, whereas maritime hardware is resource intensive, costly to deploy, and relatively limited in its sensing modalities. According to PALS program manager Lori Adornato, “Tapping into the exquisite sensing capabilities of marine organisms could yield a discreet, persistent, and highly scalable solution to maintaining awareness in the challenging underwater environment.” The DARPA-funded PALS teams must develop or apply technologies to record stimulus responses from observed organisms, and develop combined hardware and software systems that interpret those responses, screen out false positives, and transmit analyzed results to remote end users. The teams' solutions will incorporate technologies such as hydrophones, sonar, cameras, and magnetic, acoustic, and kinetic sensors. The team led by Northrop Grumman Corporation, under principal investigator Robert Siegel, will record and analyze acoustics from snapping shrimp and optical activity by bioluminescent organisms. The team led by the Naval Research Laboratory, under principal investigator Lenny Tender, will integrate microbial organisms into a sensing platform to detect and characterize biological signals from natural microorganisms that respond to the magnetic signatures of underwater vehicles. The team led by Florida Atlantic University, under principal investigator Laurent Cherubin, will record and analyze vocalization cues from goliath grouper in tropical and subtropical environments. The team led by Raytheon BBN Technologies, under principal investigator Alison Laferriere, will use snapping shrimp as sources of opportunity for long-range detection, classification, and tracking of underwater vehicles. The team led by the University of Maryland Center for Environmental Science, under principal investigator David Secor, will tag black sea bass with sensors to track the depth and acceleration behaviors of schools of fish that are perturbed by underwater vehicles. DARPA is also funding the Naval Undersea Warfare Center, Division Newport, under principal investigator Lauren Freeman, to develop a seafloor system that uses a hydrophone array and acoustic vector sensor to continuously monitor ambient biological sound in a reef environment for anomalies. The system will analyze changes in the acoustic signals radiated by the natural predator-avoidance response of coral reef ecosystem biota, which could offer an indirect mechanism to detect and classify underwater vehicles in near-real time. DARPA conceived of PALS as a four-year research program with the expectation that researchers will be able to publish results for review by the broader scientific community. However, if DARPA identifies any of the data, results, or technical specifications as controlled unclassified information, DARPA will require the PALS researchers to protect them to prevent proliferation outside of official channels. https://www.darpa.mil/news-events/2019-02-15
