How The Army Uses Microsoft’s HoloLens On The Battlefield

The headset is impressive — better than any augmented reality experience, including Magic Leap, which also tried to win the Army contract. The project is also a showcase for the Army’s plans to work more closely with America’s tech companies to speed innovation in military. The military calls its special version of the HoloLens 2IVAS,” which stands for Integrated Visual Augmentation System. It’s an augmented-reality headset, which means it places digital objects, such as maps or video displays, on top of the real world in front of you. Several companies are betting big on AR as the future of computing, since it will allow us to do much of what we can on a computer but while looking through glasses instead of down at a phone or at a computer screen. Apple, Google and Magic Leap are all building AR-capable software and hardware.

Put the headset on and pulled it down so that your eyes are peering through a glass visor. That visor is capable of displaying 3D images, information, my location and more. IVAS isn’t nearly finished.

Guided Bullet Modifies Its Course To Hit Moving Target

DARPA’s Extreme Accuracy Tasked Ordnance (EXACTO) program, which developed a self-steering bullet to increase hit rates for difficult, long-distance shots, completed in February its most successful round of live-fire tests to date. An experienced shooter using the technology demonstration system repeatedly hit moving and evading targets. Additionally, a novice shooter using the system for the first time hit a moving target.

This video shows EXACTO rounds maneuvering in flight to hit targets that are moving and accelerating. EXACTO’s specially designed ammunition and real-time optical guidance system help track and direct projectiles to their targets by compensating for weather, wind, target movement and other factors that can impede successful hits.

True to DARPA’s mission, EXACTO has demonstrated what was once thought impossible: the continuous guidance of a small-caliber bullet to target,” said Jerome Dunn, DARPA program manager. “This live-fire demonstration from a standard rifle showed that EXACTO is able to hit moving and evading targets with extreme accuracy at sniper ranges unachievable with traditional rounds. Fitting EXACTO’s guidance capabilities into a small .50-caliber size is a major breakthrough and opens the door to what could be possible in future guided projectiles across all calibers.

The EXACTO program developed new approaches and advanced capabilities to improve the range and accuracy of sniper systems beyond the current state of the art. The program sought to improve sniper effectiveness and enhance troop safety by allowing greater shooter standoff range and reduction in target engagement timelines.

Growing New Cartilage To Eradicate Osteoarthritis Pain

What is graphene foam? It’s a synthetic “wonder material” made from the same carbon atoms that make up the lead in a pencilGraphene foam can be used as a “bioscaffold” to mesh with human stem cells and grow new cartilage. In addition to being incredibly strong, graphene foam conducts heat and electricity which helps neurons, or nerve cells, transmit information. Boise State researchers believe graphene foam-enhanced cartilage could one day be used to treat the joint pain caused by osteoarthritis as well as prevent the need for joint replacement. Osteoarthritis is incurable and affects half the U.S. population over the age of 65.

If we could take graphene foam, adhere a patient’s own stem cells on it then and inject that into someone’s knee to regrow their own cartilage, that would be the ‘pie in the sky,‘” said Dave Estrada, co-director of the Boise State University’s Advanced Nanomaterials and Manufacturing Laboratory.

A Boise State team led by Katie Yocham, a doctoral student in the Micron School of Materials Science and Engineering, and Estrada have published a study, “Mechanical Properties of Graphene Foam and Graphene Foam-Tissue Composites,” in the Advanced Engineering Materials journal.

While earlier studies at Boise State have shown that graphene foam is compatible with cells for growing new cartilage tissue, this is the first study to investigate how that tissue would actually function in a human joint under normal stresses, including high impact activities.

Trevor Lujan, an associate professor in the Department of Mechanical and Biomedical Engineering, and one of the authors of the study, praised Yocham’s work. “Katie’s strong efforts on this project have provided the biomedical community with a rigorous characterization of the bulk mechanical behavior of cellularized graphene foam. This baseline knowledge is an important step in the rising use of graphene foam for biomedical applications,” he said.

Estrada believes the biomedical use of graphene foam may have other applications, including in the military where a majority combat injuries involve the musculoskeletal system. “Our vision is to develop novel bioscaffolds that can expedite healing, reduce the need for amputation, and help save lives,” he added.
