Negative-stiffness mechanical isolators can be used for achieving high-performance vibration isolation in a small microscope platform. It can be challenging to use microscopy for imaging materials, ...

A variable frequency driven (VFD) is a type of motor that controls the levels of frequency and voltage that alter the speed of an electric motor. The drive alters torque and motor speed and can be ...

Frequency response is defined as: A measure of the effectiveness with which a circuit, device, or system transmits the different frequencies applied to it. It is a phasor whose magnitude is the ratio ...

In the late 1800s a German physicist named Heinrich Hertz created radio waves in the laboratory. A century later, we are still expanding upon Hertz’s discovery. Radio waves make possible all wireless ...
