Learn how 4D digital holographic microscopy provides real-time, non-contact measurement of MEMS micromirror deformation, ...

With loudspeakers, an important parameter is the frequency at which their cones resonate. This clever Arduino-based tester ...

An AC resonant test system is designed to generate high alternating voltage by forming a resonant circuit between the reactor and the test object. By operating at or near resonance, the system can ...

The efficiency of wireless charging systems is limited by power loss occurring due to frequency changes in the resonant circuits that enable power transfer. These necessary modulations reduce ...

Drawing tablets have been a favorite computer peripheral of artists since its inception in the 1980s. If you have ever used a drawing tablet of this nature, you may have wondered, how it works, ...
