SPADs employ an avalanche process to generate significant current from a single photon. That results in higher power ...

Cell-sized robots can sense temperature, make decisions, and move autonomously using nanowatts of power—no external control ...

QCLs were initially developed in the 1990s, and this was a significant advance in MIR light sources. 2 Standard semiconductor ...

The P0118 code means that the engine control module (ECM) has detected a voltage signal that’s too high from the engine coolant temperature (ECT) sensor (below). In practical terms, the ECM believes ...

In everyday life, objects equilibrate with the environment. “A steaming cup of tea left on your desk eventually reaches room temperature, losing almost all memory of how it was heated,” says Prof.

If you read about Hall effect sensors — the usual way to detect and measure magnetic fields these days — it sounds ...

Abstract: Wound-rotor synchronous generators (WRSGs) are the main structures used in aircraft power systems. As a key component of WRSGs for realizing brushless commutation, rotary rectifiers (RRs) ...
