Micrometeoroids travel so fast that even a flake of paint can punch dime-sized craters in solar panels. NASA modeling shows a ...

The shock pulse intervals are set to 60 minutes, which has proven to be the most-suitable pulse frequency. Some of the original sootblowers are still operated with an unchanged operating cycle ...

Consider an application that needs a series of pulses to indicate position in which the lack of a pulse “indexes” the count. To achieve that goal, the application uses a rotating, 36-tooth sprocket ...

Here is a simple frequency doubler circuit that produces a square wave output with a precise 50 percent duty cycle. There are similar circuits in the literature [References 1, 2, 3] which require ...

Transcranial Magnetic Stimulation (TMS) is a non-invasive procedure that uses magnetic fields to stimulate nerve cells in the brain. This treatment, often used for depression, can temporarily ...
