DTS Developing In-Ear Exposure Sensors (IEES) to Help Protect Warfighters from Blast Injuries

As part of an SBIR contract through the Defense Health Agency, DTS is developing in-ear exposure sensors to help protect military personnel. DTS is proud to share the abstract we originally planned to present in-person at the 2021 Military Health System Research Symposium (MHSRS), which was unfortunately canceled this year due to the pandemic.

Detection and measurement of potential injury due to blast overpressure and blunt impact have been priorities of the US military for many years, especially since Operation Enduring Freedom. DTS has
developed a new, innovative 6DOF and blast dosimeter that is much smaller and more accurate than any other system. Testing of this device has proven that the prototype is able to both recognize and capture blast even at <1psi, which is a range not often captured by other devices. This dosimeter device, can be powered by a hearing aid battery and weighs <3g can be integrated with other protective equipment like helmets, footwear and tactical headsets while remaining unobtrusive to the wearer.

MHSRS is the Department of Defense’s premier scientific meeting that focuses specifically on the unique medical needs of the Warfighter. The annual educational symposium brings together healthcare professionals, researchers, and DoD leaders. The original DTS Abstract was titled Standardization of Blast and Unconventional Exposure Novel Injuries – Developmental Efforts of In-Ear Exposure Sensors.

NASA Orion Space Capsule Drop Test

April 9, 2021

NASA’s Langley Research Center in Hampton, Virginia began a new series of four water impact drop tests. According to NASA, this series of drop tests began March 23, 2021 to finalize computer models for loads and structures prior to the Artemis II flight test, NASA’s first mission with crew aboard Orion. Artemis II will carry astronauts around the Moon and back, paving the way to land the first woman and next man on the lunar surface and establish a sustainable presence at the Moon under the Artemis program.

For the April 6, 2021 test, the 14,000 lb. structural test vehicle was instrumented with DTS data acquisition systems and 500 channels of strain gauges, accelerometers and rotational rate sensors. The capsule was then vertically dropped into the Hydro Impact Basin at NASA’s Langley Research Center’s Landing and Impact Research Facility. The goal: better understand what Orion and its crew may experience during its final landing in the Pacific Ocean as part of the Artemis mission to the moon.

 

For over two decades, NASA has used DTS data acquisition systems to capture critical test data on helicopter crash landings, capsule drop testing, LDSD-low density supersonic decelerator and aerobrake testing. Providing accurate test data prior to real-live missions is an important part of research for understanding crash dynamics and improving occupant safety in any arena.

As a leading manufacturer of data acquisition systems and sensors for injury biomechanics testing, DTS is proud to sponsor National Biomechanics Day on April 7, 2021. It is exciting that National Biomechanics Day has now “Gone International” with universities, laboratories and high schools from around the world participating in what has become a global day of science and inspiration.

Over the last 30 years, DTS test and measurement solutions have been a critical component in a variety of important biomechanics testing, including the development of the U.S. Army WIAMan Blast Manikin (officially known as the Warrior Injury Assessment Manikin). The ‘human response’ of WIAMan is based on extensive biomechanics and cadaveric research done in partnership with top universities throughout the country. Each university focused on key injury areas primarily in the lower extremities like the spine, pelvis and feet to create predictable under-body blast UBB patterns. The data also allowed the team to develop a Finite Element Model, an extenstive software-based injury library, in addition to validated analysis techniques.  

According to the National Biomechanics Day (NBD) event organizers, biomechanics investigates the broad expanse of biology in the physical world and it makes substantial contributions to basic biology, medicine and health, human and animal movement and performance, biomedical engineering, prosthetics and human-machine interactions, among many other endeavors. National Biomechanics Day seeks to expand the influence and impact of Biomechanics on our society. By teaching young people about Biomechanics, one goal is that this will increase the number of people entering Biomechanics and create more career opportunities in Biomechanics. Careers may focus on Biomechanics science, but may also include the practical application of Biomechanics in commercial, medical, industrial, and other settings. As the number of biomechanists increases, so will the impact on society as well as society’s understanding and appreciation of Biomechanics in the hopes of making Biomechanics the “breakthrough science of the 21st century.”

All NBD events and activities involve young people performing isokinetic tests, or EMG tests, or mo-cap tests, or so many other living-science activities. The end result after each and every NBD test is amazement and awe, which supports the NBD motto of “Science meets fun on National Biomechanics Day.”

DTS is also proud that National Biomechanics Day has had tremendous success in reaching diverse and underserved populations, as NBD enacts extensive initiatives to expand this success. Inspiring new generations to learn the importance of biomechanics goes well beyond the fact that its techniques are the basis for all video games played today. When students see motion capture (mo-cap) in real life, biomechanics then becomes science with purpose for high school youngsters because they participate in it.

DTS salutes and celebrates National Biomechanics Day and the contributions of many the Biomechanists around the world.

U.S. Army Deliveries & First-Ever Test with 12 WIAMan

The latest shipment of five additional WIAMan Blast Test Manikins was delivered to the U.S. Army in December. Just prior to that shipment marked the first time that twelve WIAMan were gathered and operated together as a full-capacity test system. The new WIAMan, plus 2 development and 5 production manikins, were all gathered in DTS’s ATD Lab located in Seal Beach, CA for system validation testing and some ‘family’ photos.

“This was our first chance to test the External Distributor at full capacity. There literally have never been 12 WIAMan in existence, let alone all in one place,” said Tamer Abubakr, ATD Systems Manager at DTS. The test involved connecting all 12 WIAMan to a single Distributor, which manages test communication commands. As anticipated, the test was a success.

DTS’s involvement with the WIAMan project includes building the actual ATD (anthropomorphic test device), as well as the SLICE6 data acquisition system embedded inside and ancillary equipment like the External Distributor. Each WIAMan supports up to 156 sensor (data) channels. “A single exit cable from each ATD gets plugged into the External Distributor to manage communication, status, trigger, IEEE 1588 synchronization, and backup power if needed,” explained Abubakr.

U.S. Army WIAMan Blast Manikins were gathered at the DTS ATD Lab in California for a ‘family’ photo and the first opportunity to test some of the support equipment at full capacity with 12 WIAMan. 

Tamer then went on to explain in general terms how a blast test is set-up. First the miniature data recorders and sensors are embedded inside each WIAMan. The manikins are then positioned in the test vehicle and an exit cable from each ATD is run to the External Distributor. The Distributor sends commands to and from each ATD, and it’s secured in a blast bunker many meters away from the actual blast site. While one External Distributor can ‘talk’ to up to 12 WIAMan at a time, the official Command Center is miles away and manages the complete test set-up and trigger which is transmitted via fiber optic cables to the Distributor and then to each WIAMan.

DTS is prepared to deliver additional WIAMan to the U.S. Army as part of the contract, which includes up to 40 WIAMan in total. An official 700-page WIAMan accreditation report is currently under review by the U.S. Army, which will make WIAMan the first ever accredited ATD for use in under body blast testing.

DTS has been part of the WIAMan development team from the initial concept phase, including being chosen as the prime contractor to the U.S. Army. The Warrior Injury Assessment Manikin represents one of the most advanced collaborations of injury biomechanics research, engineering, manufacturing and testing. “WIAMan is the most hi-tech, biofidelic soldier surrogate in existence. It’s all about the data and each underbody blast (UBB) test provides more data to help keep our warfighters safer,” added Abubakr.

DTS External Distributor
All 12 WIAMan were connected to the DTS External Distributor which manages communication, status, trigger and IEEE 1588 synchronization for the underbody blast testing. This marks the first time that a dozen WIAMan existed and could be gathered in one place.
