Single-phase power factor correction (PFC) circuits—a kind of front-end AC/DC converters—are ubiquitous in a variety of ...

Researchers from Empa, EPFL and CSEM have developed a green smart sensing tag that measures temperature and humidity in real time—and can also detect whether a temperature threshold has been exceeded.

What’s the difference between a transmitter and a sensor? Nine different types of sensor transmitters. How does each type of transmitter work? What are the components of each transmitter type? Sensors ...

QSPICE is an analog and mixed-signal simulator characterized by high simulation speed, accuracy and reliability. It is a new program and can be downloaded here. QSPICE is still in the demonstration ...

The classic circuit breaker—a resettable overcurrent cutoff device—has been with us since the 1920s and is well-known for its reliable, consistent performance and a simple schematic symbol (Fig. 1).
