Abstract: A portable electronic device for detecting an electromagnetic pulse generated by a tesla coil, and selectively a pulse from natural lightning. The device has a detection circuit for electromagnetic pulses, operating to detect an observed electromagnetic pulse having a frequency at least within a range of about 50 kilohertz (kHz) to about 300 megahertz (MHz). The detection circuit generate an output signal corresponding to the observed electromagnetic pulse. A microcontroller analyzes the output signal from the detection circuit against a tesla profile that identifies a detected electromagnetic pulse as a tesla coil pulse when the observed electromagnetic pulse has a frequency within the range of about 50 kHz to about 300 MHz with a pulse duration of at least 0.50 seconds. The microcontroller then generates an indication that the detected electromagnetic pulse is that of a tesla coil, and generates a tesla coil alert, typically flashing of an LED.

Abstract: A device and method for the treatment of fluids using electrostatic fields generated by a high voltage electric current, which reduces or eliminates calcification, scaling and microbiological contamination. A high voltage DC current is applied to a core electrode, generating an electrostatic field which traverses a dielectric sleeve surrounding the core electrode and charges the exterior surface of the dielectric sleeve, charging inorganic particles and, in the case of a biological contaminant such as bacteria, killing the organism. Fluid flowing through the device is agitated by a combination of spiral vane sections surrounding the dielectric sleeve and helical baffle sections lining the housing wall. Charged inorganic particles coalesce into spherical aggregates which resist adhesion to pipes and vessels and can be filtered by techniques such as reverse osmosis without deteriorating the filter membrane.
