Protect battery packs against overcurrent and overcharging

Littelfuse has announced the new ITV4030, a series of 22-A, three-terminal, surface-mountable Li-ion battery protectors ideal for use in a wide range of data communications interfaces for consumer electronics including tablets, robotic appliances, and power tools. These 4- x 3-mm devices protect battery packs against overcurrent and overcharging (overvoltage) conditions. The innovative design uses embedded fuse and heater elements that provide fast response and reliable performance to interrupt the charging or discharging circuit before the battery pack becomes overcharged or overheated.

What can you do with touchless magnetic angle sensors?

Novotechnik has put together a really informative video highlighting real-world applications for their RFC, RFE, and RSA Series touchless magnetic angle sensors. You may be surprised at the variety of off-highway, marine, material handling, and industrial uses. You'll learn how they work (using a Hall effect microprocessor to detect position) and their key advantages, including eliminated wear and tear on these non-mechanical components. We love when manufacturers provide such useful examples.

Radiation-hardened GaN transistor for space applications

EPC has just introduced the EPC7018 radiation-hardened GaN FET. With higher breakdown strength, lower gate charge, lower switching losses, better thermal conductivity, and very low on-resistance, power devices based on GaN significantly outperform silicon-based devices. They enable higher switching frequencies resulting in higher power densities, higher efficiencies, and more compact and lighter-weight circuitry for critical spaceborne missions, including DC-DC power, motor drives, lidar, deep probes, and ion thrusters.

Northrop Grumman developing prototype AI assistant for Blackhawk copter pilots

Northrop Grumman's prototype AI assistant will help rotary pilots perform expected and unexpected tasks such as augmenting the crew's response to an engine fire: 1. Banking attitude adjustments not responding accordingly; 2. Establish engine air speed; 3. Establish that there is a fire; 4. Turn off the engine that's on fire and resume approach.

The Defense Advanced Research Projects Agency's (DARPA) Perceptually enabled Task Guidance (PTG) program has awarded Northrop Grumman a contract to develop a prototype artificial intelligence (AI) assistant. The prototype will be embedded in an augmented reality (AR) headset to help rotary pilots perform "expected and unexpected tasks."

In partnership with the University of Central Florida (UCF), Northrop Grumman will develop what's called the Operator and Context Adaptive Reasoning Intuitive Assistant (OCARINA). It will support UH-60 Blackhawk pilots, who fly with both visual and instrumented flight, which varies with weather, time of day, and other environmental factors.

"The goal of this prototype is to broaden a pilot's skillset," said Erin Cherry, senior autonomy program manager, Northrop Grumman. "It will help teach new tasks, aid in the recognition and reduction of errors, improve task completion time, and most importantly, help to prevent catastrophic events."

Rotorcraft aircrews face numerous demands, particularly when flying in close proximity to buildings, terrain, and people, and from the threat of adversary RADAR systems. Today, simple warning systems are the most common means for aiding a rotorcraft aircrew, such as auditory alerts to increase altitude. These warning systems are limiting and can induce unanticipated cognitive burdens on pilots. According to Northrop Grumman, studies have shown that inattentional blindness to such warnings can occur, often making them ineffective for the aircrew.

DARPA's PTG program aims to develop AI technologies to help users perform complex mental and physical tasks. The goal is to provide users of PTG AI assistants with wearable sensors that allow the assistant "to observe what the user perceives -- and know what the user knows." Using advanced information processing and an AR interface, the goal of the program is to have the AI assistant provide feedback and guidance through speech and aligned graphics at the right place and time to augment the aircrew.

Using powerful, proven algorithm development and implementation processes, Northrop Grumman is tasked to develop and integrate leading-edge AI solutions into large, complex, end-to-end mission systems that are essential to our national security. Northrop Grumman says its AI systems are developed using responsible AI principles. The company's AI technologies are "equitable, traceable, reliable, governable, auditable, and protected against threats."
