Watchdog timers (WDTs) watch MCU operations to ensure reliability, especially in embedded systems, robotics, medical devices, electric grid monitoring, deep space missions, and other critical applications. They are used to detect and correct MCU and software glitches without human intervention. The WDT monitors system operation by listening to signals from the MCU.

The Coherent Hub Interface (CHI) is used in system-on-chip (SoC) designs to track which processor has the most recent copy of a data block, preventing other processors from using old data. CHI is used in a wide range of applications requiring high-performance cache coherence, such as mobile devices, networking equipment, automotive systems, and data centers.

Cryogenic (cryo) microwave (µw) power measurements are vital for advancing quantum computing. Delicate quantum devices require operation at cryo temperatures to maintain coherence and stability. Accurate power measurements at cryo temperatures are also required to optimize and debug quantum hardware. This article begins by reviewing cryo zones in a quantum computer and the related µw metrology needs.

Mobile edge computing (MEC), also called multi-access edge computing or simply multi-access computing, is part of the confluence of the Internet of Things (IoT) and mobile devices. MEC doesn’t mean processing data on mobile devices. MEC simply processes data closer to its origin. Instead of sending data to the cloud, MEC utilizes edge computing resources like nearby servers or cell towers.

There are many ways to arrive at a less-than-optimal electronics hardware solution. This article is an overview, not a comprehensive compilation of possible hardware engineering errors and how to avoid them. Common errors include incorrect component selection, poor circuit design practices, such as grounding or signal integrity issues, improper power supply specifications, neglecting thermal management, and failing to adequately account for environmental factors like moisture or vibration.

Vertical-cavity surface-emitting lasers (VCSELs) are used in biomedical sensors because they emit highly focused, coherent light at specific wavelengths, enabling precise detection and analysis of biomolecules. Applications include blood oxygen level monitoring, optical coherence tomography (OCT) for imaging tissue structures, fluorescence microscopy, and analysis of live biomolecules in lab-on-a-chip systems.

A 5G core (5GC) provides the central control and management for a 5G network. It roughly corresponds with the Evolved Packet Core (EPC) that supports converged voice and data services on a 4G Long-Term Evolution (LTE) network. The 4G EPC is a flat architecture using point-to-point connectivity and is limited in scalability. The 5GC is cloud native and is a service-based architecture (SBA). The use of the cloud supports independent network functions (NFs) in the form of containerized microservices.

Maneuverability and guidance systems, not just raw speed, are key differentiators for hypersonic missiles. That requires aerodynamic pressure sensors, optical sensors, inertial sensors, space-based tracking, infrared sensors, and more. All are combined into a single guidance system using sensor fusion. This article reviews the sensor types for hypersonic guidance, navigation, and target acquisition systems. Hypersonic guidance systems and associated sensors are an evolving technology.

The 5G protocol stack is the architecture of protocols within a 5G network that perform specific functions like managing data transmission, error correction, and resource allocation. It exists as two separate elements: the control plane (CP) and the user plane (UP). It’s more complex than the 4G protocol stack due to the numerous advanced features and technologies added in 5G.

If an application calls for a device with multiple inputs and a single output, it needs a multiplexer. A switch can be used if the need is for one input per output. Analog switches and multiplexers are used in a wide array of systems, including industrial, medical, military/aerospace, consumer, 5G infrastructure, and more.
