1. A device for detecting and measuring short pulse-type signals such as ESD Events and surges, comprising:
- means for receiving a signal and converting the electromagnetic field into an electric signal;
resonance means that creates, from a short duration received electrical signal, a new secondary self-resonating signal with a longer duration having a magnitude that is a function of the magnitude of the received signal, wherein slower input signals will not create strong secondary resonance signals and will not be measured; and
signal measuring means for measuring the amplitude of the self-resonating signal in order to provide an analog or digital representation of the magnitude of the received filtered signal.

17. A power supply isolation apparatus, comprising:
-
first switching means that connect a first storage means to the output of a power source;
second switching means that connects said first storage means to a second storage means, the second storage means being connected to the electric load; and
a controller for controlling the first and second switching means where both the switching means connect the first storage means alternatively to either said power source or to said second storage means in a non-overlapping manner so that said first storage means charge from said power supply and discharge into said second storage means in a manner where said second storage means and said electric load are never directly connected to said power supply and no interference signal is passed from said power supply.

18. A power supply isolation apparatus, comprising:
-
a first switching means that connect a first storage means alternatively to either a power supply or to an electric load; and
a second switching means that alternatively connect a second storage means to either said power supply or to said electric load where said first switching means and said second switching means operate in a non-overlapping manner when one storage means is connected to said power supply for charging and another previously charged storage means provides power to said electrical load so that said electric load is never directly connected to said power supply and no interference signal is passed from said power supply. - View Dependent Claims (19, 20)
