DSEi 21 – Molliflex

Wednesday, September 22nd, 2021

Sometimes at a trade show you zig instead of zag? and when I turned left instead of right on my last say at DSEi I ran smack dab into the Intelligent Textiles Limited stand and their Molliflex cables.

The lady in the stand read my badge aloud, “soldier systems” and as she did it I looked at what they were doing and replied?, “you’re right in my wheelhouse.” Turns out, this is the gem I was searching for at DSEi, that one product I didn’t expect to find, but has great potential.

They’ve done such a good job with their Molliflex cable, that you probably didn’t even notice it in the photo at first or maybe even second glance.

The cable is just 2mm thick and can be woven into PALS compatible platforms. Due to how things it is, pouches can be added over Molliflex. Molliflex lays flat even when folded for 90 degree turns. In fact, it can be folded over two million times before the internal connection is broken. Additionally, it is IP68 rated. The connector is a standard Glenair Mighty Mouse which is Nett Warrior compliant.

Attachments to devices include an Ejector QD plug and Hardpoint attachment plate.

It is rated for power at 5amps,<50voltsDC1 and data at USB 2.0, 480 Mbps.

The outer material is DWR coated nylons me available in Multicam, Coyote, Flecktarn, CADPAT, and Black.

Army Modernizes Tactical Power with Battery Interoperability

Wednesday, September 22nd, 2021

ABERDEEN PROVING GROUND, Md. — The Army is modernizing tactical power and reducing logistics costs by developing standardized batteries for Soldier-worn and handheld equipment such as radios, GPS, night-vision devices and weapons.

Army Futures Command (AFC) engineers are leading the project to deliver eight sizes of batteries that share a common mechanical and electrical interface — the key to unlocking interoperability.

The Small Tactical Universal Battery (STUB) is the Army’s latest approach to develop a standard family of batteries, according to Dr. Nathan Sharpes, a research mechanical engineer with the Command, Control, Communications, Computers, Cyber, Intelligence, Surveillance and Reconnaissance (C5ISR) Center — a component of AFC’s Combat Capabilities Development Command (DEVCOM).

“Now is an opportune time to standardize power sources as the Army is prioritizing modernization and fielding electronics with greater capabilities requiring more energy than current systems,” Sharpes said.

The C5ISR Center is leading the program that will benefit Soldiers, the acquisition community, logistics personnel and industry, Sharpes said. The goal is to avoid the current model of fielding a proprietary battery for each piece of gear as technology developers have historically delivered unique batteries for new capabilities.

Each battery size provides a different amount of energy, from which Soldiers could choose, depending on their mission needs. This interoperable battery system will seamlessly deliver the correct voltage and power level needs to any device.

“Currently when a Soldier is on a mission carrying five different pieces of gear that each have a unique battery form factor, along with spares, that’s extra weight and items to keep track of,” Sharpes said. “With this family of interoperable batteries, Soldiers will see benefits cognitively and physically.

“Any battery in the STUB family will be able to attach to any device designed for it because of the standard interface. We’re also incorporating eight attachment methods — such as slide on, clip in and twist on — so devices can use the universal battery in different ways. Soldiers can focus more on their missions and less on which types of batteries and how many of each to carry.”

Standardization also alleviates the burden of battery design from manufacturers of handheld electronics. As industry develops new C5ISR technologies, they will be able to concentrate on core competency areas while adhering to the already approved universal-battery specifications. All vendors would follow the same battery guidelines, Sharpes said.

The new standard universal-battery sizes will also simplify logistics and reduce supply chain costs, as the Army will be able to move away from procuring, storing, testing and shipping a wide array of unique batteries required for each piece of Soldier-carried equipment, Sharpes said.

The C5ISR Center’s STUB initiative follows in the footsteps of the Army’s development of the thin, flexible Conformal Wearable Battery (CWB) that Soldiers wear on their vests as a central power source for wearable electronic devices, according to Christopher Hurley, chief of the Center’s Tactical Power Branch.

The CWB development aimed to reduce the number of battery types needed by enabling a single power source to provide extended runtime to select pieces of kit. Current Army research would enable equipment to use smaller STUB batteries when not connected to the CWB.

“The end result is an overall lighter and more energy dense Soldier kit,” Hurley said. “The C5ISR Center is working across Army organizations to create battery standards and specifications. These efforts will meet the demands of the numerous pieces of equipment a Soldier uses and the diverse operating environments in which they conduct missions.”

Galvion Releases a New Range of Data Compatible Accessories to Support their Active Systems Concept at DSEi

Friday, September 10th, 2021

Galvion, a world leader in the design and manufacture of military power management solutions, with operationally proven pedigree in NATO countries, has released three new key products as part of their integrated Active Systems capability that facilitates the harvesting, distribution and management of dismounted soldier power, data and software. The announcement coincides with the DSEi exhibition taking place in London, 14-17 September 2021. At the show, Galvion will also be exhibiting their range of next generation head systems and Li-ion platform power solutions on stand H1-424.

To be mission effective, the modern soldier is required to carry, operate and maintain a host of devices that all demand significant power and data capacity – for example radios, NVGs, GPS, smart phones, laptops, drones and other surveillance equipment.  Galvion has released three new products that integrate with their existing soldier power systems, to better support the dismounted soldier in managing these increasing technology demands.  These products are flexible, scalable and comply with US NettWarrior and NATO STANAG 4695 standards for backward compatibility, ease of integration with other product ranges and improved logistic sustainability on the battlefield.

The Power and Data Hub 4-Port (PDH-4) provides a multi-function power and data connection between the basic soldier-worn architecture, such as hand-held radios and smart devices, and a suitable power source. The PDH-4 enables the soldier to send and receive data through the connection with the soldier worn devices, increasing situational awareness through system integration.  When combined with the PWS it maximises the distribution and use of harvested power sources and is ready for the soldier’s future data sharing demands and software updates.

The Personal Worn Power Scavenger (PWS) provides a highly adaptable interface to allow the soldier to harvest power from multiple sources such as solar panels, 12V systems, mains power or other squad or personal power sources such as SoloPackTM.  The PWS can be used in isolation or combined with other products, such as the PDH-4, to increase utility and the number of devices that can be charged.

The third new product, the Radio Power Adapter (RPA), easily integrates with most common hand-held radios in use today. This adapter provides power to the main radio battery by connecting to a main soldier-worn power source and keeping it charged and ready for when the radio is disconnected from the soldier-worn architecture. The Radio Power Adapter supports the AN/PRC-148 MBITR, Falcon III AN/PRC-152A and the AN/PRC-161 Link-16. The RPA also reduces the number of radio batteries a user needs to carry and fits into their existing load carrying system.

Kristen Lomastro, President of Active Systems, said: “Galvion has been leading the way for soldier power management and distribution systems with their NervCentr® products and I am extremely pleased to announce the release of these three new products to augment our dismounted soldier capability.  With their small form factor, these products easily integrate into existing soldier-worn equipment and are compatible with other soldier systems. They also provide the hardware infrastructure to support our mission-enabling software making them future-ready.  Galvion always places the soldier first, and we pride ourselves on designing solutions that help to protect and support those who protect us.”

Turning Thermal Energy into Electricity Could Help Soldiers

Sunday, September 5th, 2021

RESEARCH TRIANGLE PARK, N.C. — With the addition of sensors and enhanced communication tools, providing lightweight, portable power has become even more challenging. Army-funded research demonstrated a new approach to turning thermal energy into electricity that could provide compact and efficient power for Soldiers on future battlefields.

Hot objects radiate light in the form of photons into their surroundings. The emitted photons can be captured by a photovoltaic cell and converted to useful electric energy. This approach to energy conversion is called far-field thermophotovoltaics, or FF-TPVs, and has been under development for many years; however, it suffers from low power density and therefore requires high operating temperatures of the emitter.

The research, conducted at the University of Michigan and published in Nature Communications, demonstrates a new approach, where the separation between the emitter and the photovoltaic cell is reduced to the nanoscale, enabling much greater power output than what is possible with FF-TPVs for the same emitter temperature.

This approach, which enables capture of energy that is otherwise trapped in the near-field of the emitter is called near-field thermophotovoltaics or NF-TPV and uses custom-built photovoltaic cells and emitter designs ideal for near-field operating conditions.

This technique exhibited a power density almost an order of magnitude higher than that for the best-reported near-field-TPV systems, while also operating at six-times higher efficiency, paving the way for future near-field-TPV applications, according to Dr. Edgar Meyhofer, professor of mechanical engineering, University of Michigan.

“The Army uses large amounts of power during deployments and battlefield operations and must be carried by the Soldier or a weight constrained system,” said Dr. Mike Waits, U.S. Army Combat Capabilities Development Command’s Army Research Laboratory. “If successful, in the future near-field-TPVs could serve as more compact and higher efficiency power sources for Soldiers as these devices can function at lower operating temperatures than conventional TPVs.”

The efficiency of a TPV device is characterized by how much of the total energy transfer between the emitter and the photovoltaic cell is used to excite the electron-hole pairs in the photovoltaic cell. While increasing the temperature of the emitter increases the number of photons above the band-gap of the cell, the number of sub band-gap photons that can heat up the photovoltaic cell need to be minimized.

“This was achieved by fabricating thin-film TPV cells with ultra-flat surfaces, and with a metal back reflector,” said Dr. Stephen Forrest, professor of electrical and computer engineering, University of Michigan. “The photons above the band-gap of the cell are efficiently absorbed in the micron-thick semiconductor, while those below the band-gap are reflected back to the silicon emitter and recycled.”

The team grew thin-film indium gallium arsenide photovoltaic cells on thick semiconductor substrates, and then peeled off the very thin semiconductor active region of the cell and transferred it to a silicon substrate.

All these innovations in device design and experimental approach resulted in a novel near-field TPV system.

“The team has achieved a record ~5 kW/m2 power output, which is an order of magnitude larger than systems previously reported in the literature,” said Dr. Pramod Reddy, professor of mechanical engineering, University of Michigan.

Researchers also performed state-of-the-art theoretical calculations to estimate the performance of the photovoltaic cell at each temperature and gap size and showed good agreement between the experiments and computational predictions.

“This current demonstration meets theoretical predictions of radiative heat transfer at the nanoscale, and directly shows the potential for developing future near-field TPV devices for Army applications in power and energy, communication and sensors,” said Dr. Pani Varanasi, program manager, DEVCOM ARL that funded this work.
