Noisefighters and 4D Tactical Introduce Heatsync, A Sweat-Wicking, Silver-Embedded Fabric Ear Pad Cover for Headsets

Tuesday, April 20th, 2021


NOISEFIGHTERS and its development partner 4D TACTICAL today announces the public launch of the HEATSYNCTM sweat-wicking, form-fitting fabric ear pad cover for headsets. Heatsync addresses the #1 problem with over-the-ear headsets: in hot weather, there is internal sweat accumulation and excessive heat buildup. A form-fitting cover — made 100% in the U.S.A. from advanced materials including 4D Tactical’s NanoTech silver-embedded, antimicrobial, wicking fabric — is pulled tight over the headset’s existing ear pads. In use, the Heatsync draws perspiration out from the inside of the headset and helps cool the wearer through the evaporative process, while also eliminating the slimy feeling normally associated with pressing wet rubber ear pads against the head in hot weather.

“Teaching over 70 classes a year, I practically live in hearing protection. The comfort and protection Noisefighters products offer is second to none, and the new Heatsync has only made it better. Goodbye, sweaty earpro!” said Erik “Trek” Utrecht, owner of Michigan Defensive Firearms Institute (MDFI: MDFI is a Michigan-based training company that trains over 1500 students annually with the goal of building responsibly-armed citizens that are confident and competent with their defensive tools.

“After more than two years of development, I’m extremely excited to get Heatsync out into the world. Being able to partner with 4D Tactical on this product is a dream come true, as their leadership team brings decades of experience to the table and a standing in the industry that’s really unmatched,” said Neal Brace, inventor of the product and owner of Noisefighters. “Heatsync is, to my knowledge, the first viable answer to the problem that my customers have brought up time and time again: in hot weather, how does one stay cool, or at least comfortable, while wearing a headset that is designed to seal the noise out? The solution we came up with is tightly form fitting, keeps the ear cup cavity fully open for comfort, and ensures the noise seal is totally closed for safety. It doesn’t rely on electronics, just specially-engineered fabrics and a clever design.”

4D Tactical’s leadership team, including CEO Heidi Dennis and Vice President David Dennis, said in a statement that they were, “[…] very pleased to have had the opportunity to collaborate with Noisefighters. We feel the Heatsync product provides significant improvements to conventional headset ear seals. We hope this is just the beginning of our collaboration with Noisefighters.”

Heatsync is a universal cover designed to fit every headset that uses the industry standard 4″ (102 mm) tall by 3″ (76 mm) wide oval or rectangular ear pads of thicknesses between 0.5″ (12.7mm) and 0.75″ (19mm). A stainless steel expanding spring is included to lock the Heatsync cover to the inside of each cup on the headset and keep the ear cup cavity open. The cover was tested and proven to fit all current headsets from Ops-Core®, Peltor®, Howard Leight®, Sordin®, Walker’s Game Ear®, and many brands of aviation headsets, as well. It may fit other headsets with slightly smaller, larger, or even fully circular ear pads with different thicknesses, as well, due to the stretchable fabric construction. Installation is very fast, easy, and reversible, with no evidence of the cover ever having been attached.

During extreme cold weather use, the cover additionally provides an insulative barrier between the freezing cold rubber ear pads and the user’s face. The Heatsync’s proprietary fabrics are also pleasing to the touch and add a noticeable amount of comfort versus rubber ear pads. The design is fully compatible with either foam-filled or gel-filled ear pads, and its highly-compliant fabric is a perfect fit with Noisefighters’ Sightlines gel-filled ear pads that feature a patented relief cut feature for glasses arms to pass through.

Heatsync is made in the U.S.A. and is fully Berry Amendment and TAA compliant.

Heatsync’s MSRP is $90, with product launch sale pricing set at $75. Noisefighters offers a discount program for LEO / MIL and veterans / EMS / FD / security professionals / defensive tactics instructors, with details available on its website on the FAQ page. Organizations looking to purchase in bulk can inquire about a volume discount.

Noisefighters has the Heatsync available for sale on its website and will soon make it available through its extensive, worldwide dealer network.

U.S. Inauguration’s Military Units Used Draper-developed WebTAK for Communications, Situational Awareness

Thursday, April 15th, 2021

CAMBRIDGE, MA—April 15, 2021—At the recent presidential inauguration, public safety was top of mind as thousands of military personnel were posted throughout the U.S. Capitol and the surrounding neighborhoods. Behind the scenes, a new software program developed by Draper called WebTAK gave military units a way to communicate and respond to potential threats in real-time.

The software is based on the Android Tactical Assault Kit (ATAK), which was developed by the Department of Defense and used by Special Operations forces and warfighters. ATAK has been tested through years of real-world use in combat situations, by more than 10,000 active warfighters.

After countless successful military operations, ATAK has grown to a broader product line known as TAK, which is also known as the Tactical Awareness Kit. The software has been deployed on popular technology platforms that include Android OS (ATAK), Microsoft Windows OS (WinTAK) and soon on Apple OS (iTAK). Now, along with contributing to the development of ATAK and WinTAK, Draper has developed a web-based version called WebTAK.

At the inauguration, WebTAK was used to share situational awareness and coordinate across multiple agencies. While specifics of the deployment are unavailable for security reasons, the goal of WebTAK is to enhance decision support, situational awareness (SA) and protect military and civilian populations from threats, both intentional and incidental, including chemical, biological, radiological, nuclear and high yield explosives (CBRNE).

Like ATAK, WebTAK is a geospatial collaboration platform that allows teams to share information and access data to improve real-time situation awareness. WebTAK provides a wide variety of useful SA functions including mapping and navigation, range and bearing, text chat, force tracking, geospatial markup tools, image and file sharing and video playback.

“For the first time, operators can access TAK from a password protected and encrypted website on any internet-connected device, instantly,” said Dan Nissen, a software engineer on Draper’s WebTAK team.

As the company’s technical director on WebTAK, Kyle Finley says Draper is not just about creating new technologies, but also ensuring that the full potential of those technologies is realized. “WebTAK’s foundation is a set of core capabilities built using modern web software principles and practices. The recent addition of plugin support to that core opens WebTAK to a whole new world of uses,” Finley said.

WebTAK’s Software Development Kit (SDK) gives developers a framework to quickly develop those custom plugins. These plugins enable rapid integration of innovative technologies into WebTAK, allowing the application to adapt to the continually evolving user needs for situational awareness. In other words, WebTAK was built to be flexible enough so when there is a new “must have” communication device or other technology, anyone with general coding skills can quickly write code enabling the use of that technology within WebTAK.

With WebTAK running on an internet-connected device, a user enters a URL, logs into the system and instantly receives information that can inform situational awareness of an event. The software offers protections through a secure socket layer and end-to-end encryption. As a device-agnostic application, WebTAK is designed to run equally well across various mobile or desktop devices.

“Maintaining continuous situational awareness is the foundation for maintaining security. With WebTAK, warfighters, first responders and public safety officials can customize their operating environment, depending on their role or mission, and benefit from anywhere, anytime secure connectivity through the internet,” explained Brad Vautour, sound designer and senior enterprise software engineer at Draper.

The work is sponsored by the Defense Threat Reduction Agency (DTRA). DTRA is funding development of ATAK, WinTAK, and WebTAK decision support tools, along with supporting leading edge technologies.

Machine Learning Shows Potential to Enhance Quantum Information Transfer

Friday, March 26th, 2021

RESEARCH TRIANGLE PARK, N.C. – Army-funded researchers demonstrated a machine learning approach that corrects quantum information in systems composed of photons, improving the outlook for deploying quantum sensing and quantum communications technologies on the battlefield.

When photons are used as the carriers of quantum information to transmit data, that information is often distorted due to environment fluctuations destroying the fragile quantum states necessary to preserve it.

Researchers from Louisiana State University exploited a type of machine learning to correct for information distortion in quantum systems composed of photons. Published in Advanced Quantum Technologies, the team demonstrated that machine learning techniques using the self-learning and self-evolving features of artificial neural networks can help correct distorted information. This results outperformed traditional protocols that rely on conventional adaptive optics.

“We are still in the fairly early stages of understanding the potential for machine learning techniques to play a role in quantum information science,” said Dr. Sara Gamble, program manager at the Army Research Office, an element of U.S. Army Combat Capabilities Development Command, known as DEVCOM, Army Research Laboratory. “The team’s result is an exciting step forward in developing this understanding, and it has the potential to ultimately enhance the Army’s sensing and communication capabilities on the battlefield.”

For this research, the team used a type of neural network to correct for distorted spatial modes of light at the single-photon level.

“The random phase distortion is one of the biggest challenges in using spatial modes of light in a wide variety of quantum technologies, such as quantum communication, quantum cryptography, and quantum sensing,” said Narayan Bhusal, doctoral candidate at LSU. “Our method is remarkably effective and time-efficient compared to conventional techniques. This is an exciting development for the future of free-space quantum technologies.”

According to the research team, this smart quantum technology demonstrates the possibility of encoding of multiple bits of information in a single photon in realistic communication protocols affected by atmospheric turbulence.

“Our technique has enormous implications for optical communication and quantum cryptography,” said Omar Magaña?Loaiza, assistant professor of physics at LSU. “We are now exploring paths to implement our machine learning scheme in the Louisiana Optical Network Initiative to make it smart, more secure, and quantum.”
