A device for electronic analogue simulation of transients in complex power systems and for transformation of voltage coordinates including the combination of a harmonic converter, memory units and a frequency adder. In checking transients in power systems, harmonic converter includes selective filter connected to the input of the analogue memory unit through a current detector or operational amplifiers with passive networks in their feedback loops.
An apparatus and method for treating cancer and other illnesses in humans and animals are described. The treatment involves the low-power, pulsed application of radio frequency tuned with precision of at least one half part per million. Alternative embodiments are described for apparatus that generates the required RF signals and applies such signals therapeutically. Laboratory data is reported, showing the successful use of the disclosed apparatus and methods to suppress and eliminate cancerous tumors in mice.
