The Hayek Oscillator is a non-invasive high frequency ventilator which offers the first real alternative to conventional mechanical ventilation and enhances secretion removal. The Oscillator ...

One of those was the mechanical oscillator, and [Integza] had a go at replicating the device himself. (Video, embedded below the break.) Initial attempts to reproduce the technology using 3D ...

Enter the oven controlled crystal oscillator, or OCXO. These do basically what it says on the tin, but what’s inside them? [Kerry Wong] took apart a vintage Toyocom TCO-627VC 10 MHz OCXO ...

By placing the nonlinear crystal in a cavity, an oscillator is formed and operation commences when the pump power is above a certain threshold value. A unique feature of OPOs is that the output ...
