Abstract:
1. A digital electromagnetic resonance therapy system for therapeutically treating disorders comprising: a digital electromagnetic pulse generator including a control unit comprising a microcontroller electrically connected to a power supply and a digital-to-analog converter, the digital-to-analog converter having at least two outputs, the control unit generating direct current and temporally-varying excitation waveforms at each output of the digital-to-analog converter, wherein each cycle of the excitation waveforms includes five time portions, A, B, C, D and E forming a total time period of T, portions A, B and C have a positive or zero amplitude and at least one portion includes a length of greater than zero, portion D has a negative amplitude and a length greater than zero and portion E has a zero amplitude and a length sufficient to allow all inductive energy dissipation prior to the next cycle; a plurality of low-frequency power amplifiers connected to the outputs of the digital-to-analog converters of the control unit, the low-frequency power amplifiers each having an input and an output; at least one air core electromagnetic coil connected to each of the outputs of the low-frequency power amplifiers; a current sensor monitoring the current supplied to the coil; and a temperature sensor limiting the temperature of the coil by modifying the excitation waveforms.
