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.

Long-range retro-reflective photoelectric sensors overcome interference

The new 36 series of sensors from Leuze are suitable for demanding requirements in intralogistics, packaging systems, and the automotive industry. They detect objects with different optical properties -- even at a great distance or when sources of interference are present (such as film-wrapped pallets, vibration, or ambient lighting). Available as sensors with background suppression (range to 2.5 m), as retro-reflective photoelectric sensors (up to 17 m), or as throughbeam photoelectric sensors (up to 80 m).

Neat. How to prototype 4x machine vision applications on one small embedded system quickly

Teledyne FLIR has put together a neat article that shows how to prototype a machine vision system quickly that runs four simultaneous applications, three of which use deep learning. The system uses the Quartet Embedded Solution for TX2, a customized carrier board that enables easy integration of up to four USB3 cameras at full bandwidth. The example traffic systems application includes license plate recognition, vehicle type categorization, vehicle color classification, and seeing through a windshield -- all simultaneously. Very cool.

Engineers at Teledyne FLIR Defense have created a powerful drone surveillance system that fits in the back of a standard pickup truck and can detect unmanned systems up to 3 km away -- and it can even execute a radio frequency (RF) kill chain using non-kinetic technology (soft-kill jammer immobilization, as opposed to hard-kill missiles/munitions) with a defeat range of up to 1.5 km horizontal/457 m vertical.

The new Lightweight Vehicle Surveillance System (LVSS) includes comprehensive air domain awareness (ADA) and advanced counter-unmanned aerial system (C-UAS) capabilities. The system leverages a powerful combination of 3D radar, EO/IR camera, and RF detection and mitigation sensors to provide early warning alerts and recognition. Threats are detected and displayed simultaneously, showing position and elevation for all radar tracks.

The LVSS ADA C-UAS also can detect drone swarms by allowing operators to monitor up to 500 radar targets simultaneously. A multi-spectral imager captures key UAS elements that help identify high-risk targets for a pinpointed response. Even more impressive, this is on-the-move technology that allows operators to obtain threat assessments while the system is static or while driving the vehicle.

Special consideration has been put into making sure the sensor suite can be quickly deployed (up and running in under 60 sec), stowed (less than 30 sec), and redeployed. High-performing video analytics allow operators to identify, track, and engage threats precisely. The analytics model can also be used to control the camera autonomously. Increased cyber security tools have been integrated to resist hackers. The whole system is run by the new Cameleon V5 command and control software, which integrates all onboard sensors and supports advanced device features and bi-directional communications.

Teledyne FLIR Defense is part of Teledyne Technologies.
