Board-level EMI shielding: DIY in minutes

ProtoShield sheets from Tech-Etch are depth-etched with a checkerboard pattern for folding, so they can be easily formed into many diverse configurations. In the product-development stage, fully functional shields can be created in minutes with just a pair of scissors and a straight edge for folding. Offered in two sizes: standard (.25-in. squares) and metric (5-mm squares). Both versions are solderable and corrosion resistant due to nickel silver material. Shield prototypes can be directly soldered to the board, or shield clips can be used for easy mounting. Samples available.

Isolated probing tech for fast-switching power device testing

Keysight Technologies has developed an optically isolated differential probing family dedicated to enhancing efficiency and performance testing of fast-switching devices such as wide-bandgap GaN and SiC semiconductors. Validation of floating half-bridge and full-bridge architectures commonly used in power conversion, motor drives, and inverters requires measurement of small differential signals riding on high common-mode voltages. This measurement can be challenging due to voltage source fluctuations relative to ground, noise interference, and safety concerns.

What is a braking resistor?

According to Automation-Direct, "Braking resistors don't actually provide braking directly -- rather, they allow a drive to stop a loaded motor faster." Why is this important? Protect your AC or DC drive system from regenerative voltage that can create an over-voltage fault on the drive -- especially with high inertial loads or rapid deceleration.

By Jasmyne Douglas, U.S. Army CCDC

The U.S. Army will use next-generation cellular network technology to improve the versatility and flexibility of tactical networks and gain an advantage during multi-domain operations.

The Combat Capabilities Development Command's (CCDC) Command, Control, Communications, Computers, Cyber, Intelligence, Surveillance and Reconnaissance (C5ISR) Center -- part of Army Futures Command -- is studying network slicing, a 5G technology that enables the creation of multiple virtual networks, known as "slices," over a shared physical network.

Network slicing uses software to orchestrate and customize the capacity, latency, and cybersecurity of each slice to support mission-specific needs.

"This technology will give our Army networks almost instantaneous adaptability," said Michael Monteleone, the C5ISR Center's director of Space and Terrestrial Communications. "It is going to be a tremendous upgrade to how we're currently operating our networks."

The Army's current networks consist of many stove-piped transport networks that were developed for specific purposes, Monteleone said. They lack the scale, throughput, speed, mobility, and availability needed to connect multiple devices on the battlefield into a seamless network.

"Dominance against near peer threats in future operating environments requires a highly agile and secure network connecting every Soldier, sensor, weapon, device, autonomous platform, and manned vehicle," said Dr. Akber Qureshi, chief engineer for the C5ISR Center's Tactical Communications Division. "Network slicing will transform the tactical network from a rigid and slow-to-adapt network into a high-performance and flexible network that can be configured on demand."

The Army will leverage commercial investments in the technologies that enable network slicing: software-defined networking, network function virtualization, and network programmability.

As those technologies mature, the C5ISR Center will help to incorporate them in Army science and technology programs and deliver tactical capabilities as early as fiscal year 2023.

"We are addressing military-specific requirements of security, infrastructure mobility, and resilience in congested and contested operating conditions," said Qureshi. "Leveraging commercial 5G efforts and surgically investing in gap technologies will allow for the realization of a more capable, flexible, intelligent, and tactical network."

Ultimately, network slicing will be used to support autonomous vehicles, time-critical sensor-to-shooter connectivity, heads-up displays, high-resolution video feeds, and intelligence data retrieval -- all on the same network.

"We have a need and desire to partner with industry to explore what they are doing and how we can use what is normally created for a commercial use and repurpose it for the military," Monteleone said.

He encourages industry representatives with an interest in supporting the Army's research to request a Technical Interchange Meeting via the organization's website at https://c5isr.ccdc.army.mil/opportunities_and_services/business_opportunities/.
