How to Design in VAD Users needs to be able to give AI glasses voice commands and be sure the device is only picking up their speech, not other sounds. Vibration from the user's voice is the key to the next evolution of voice commands, one that engineers can tap into with accelerometer technology. As humans, we use our voice to communicate every day. So, it's no wonder that technology that taps into voice continues to grow rapidly.

Infineon Technologies AG is collaborating with Amazon Web Services (AWS) to accelerate microcontroller (MCU) evaluation to shorten development cycles for automotive systems. As part of this collaboration, Infineon is launching a cloud-based platform for virtual evaluation of Infineon automotive MCUs, powered by AWS.

GigaDevice, a leading semiconductor company specializing in Flash memory, 32-bit microcontrollers (MCUs), sensors, and analog products, has introduced the new GD32E512 and GD32E252 series MCUs specifically designed for optical module applications.

Microchip Technologyhas announced that its MPLAB® XC Pro Compilers and MPLAB Machine Learning (ML) Development Suite are now available at no cost to customers. By enabling unlimited installs across individual and team environments, these tools give developers free access to advanced optimization capabilities and integrated embedded machine learning workflows.

How to Trace MCU Code in (Almost) Real Time How do you trace code execution in an MCU? This month, Stuart looks at the problem and offers real-time solutions. Many years ago, I went to work for a company that had recently been acquired. They had a new product in development and the acquisition had delayed things. They were scrambling to meet deadlines. This was back when the 8088/8086 were state-of-the-art microprocessors and emulators were the size of a shoebox.

Epson Timing has introduced a new, low-power, oven-controlled crystal oscillator engineered to deliver the ultra-stable timing performance required for AI, edge, and next-generation communication infrastructures, while reducing power consumption and design footprint. The new OG7050CAN is verified to consume 56% less power than earlier Epson OCXOs and is 85% smaller by cubic volume, helping to enable equipment designers to improve efficiency without compromising timing precision.

Tektronix® unveiled two additions to its power measurement portfolio: the wideband shunt for IsoVu™ isolated current probes and the THDP0400 high voltage differential probe. The launches address a growing challenge in power electronics design.

Valvoline TM Global Operations, The Original Motor Oil 1 and worldwide leader in automotive and industrial solutions, announced Beyond by Valvoline - a new generation fluid platform engineered to meet the rigorous demands of today's most advanced technologies. These technologies include high-performance computing environments and utility-scale battery storage, as well as emerging innovations currently taking shape.

Sometimes, too much can be just enough. In this article, Jacob shows why learning an RTOS that's more than you need can be just what you need for your growing skillset. Most developers start their careers with a bare-metal loop or the smallest RTOS they can find. It works fine for blinking LEDs and reading sensors. But as soon as you need portability, observability, or the ability to scale across dozens of boards, the cracks begin to show. This is where Zephyr RTOS enters the picture.

Axonis, the AI solutions developer that governs high-stakes decisions across distributed data, introduced Multiplayer Decision Intelligence, a new capability of Axonis Decision Intelligence built for an era of fragmented visibility, where the most consequential patterns span beyond organizational boundaries. Axonis Multiplayer enables enterprises, smart cities, government agencies, healthcare, and financial institutions to act on intelligence across organizations without any data being exposed.
