[Shane] has a really simple circuit he’s been working on to do just that: tell if something connected to mains is on or not, and relay that information over a wireless link. There are two basic ...

and draws so little power it’s perfect for projects with the smallest power budgets. The detector circuit uses a miniature solar cell and a JFET wired up in a small brass tube to block most of ...

4.4 Input Impedance of the di/dt detector The primary part L 1 and R 1 of the mutual inductor is inserted in series to the power supply line, and the impedance disturbs the power supply voltage for ...

The Power HyD detector family from Leica Microsystems offers high performance in spectral coverage, sensitivity & dynamic range in confocal microscopy We have developed a new family of detectors ...

The present IP is a VCC Detector (VDT) circuit, which prevents the possibilities of causing ... The output may be in the wrong voltage level during the power-up phase before the bandgap becomes stable ...
