Therapeutic Field Generator Device And Method
A portable therapeutic field generator device (10) generates a reduced magnetic field component for a relatively large electric field by virtue that adjacent conductive tracks in a radiating element (40, 50) conduct electrical current in opposing directions. The device (10) includes a processor (12) that, in response to a control algorithm stored in memory (14), supplies a pulse wave (22) to a circuit containing the radiating element (40, 50). The pulse establishes generation of a base heartbeat reference having a frequency around a nominal heart rate. At periodic times, the base heart beat reference is supplemented by mutually exclusive periods of alpha wave, theta wave and delta wave generation (or other selected frequencies below about 200 Hz) based on selected brainwave frequencies for these waves, with the pulses having a duration generally corresponding to that ascribed to neuron depolarisation pulses. The device (10) cycles through multiple cycles (88) and, dependent upon the effect that is desired, may see delta wave frequencies follow theta wave frequencies that follow alpha wave frequencies. Delays may exist between transitions between the generated waves, with delta wave generation occurring no later than sixty minutes from commencement of alpha wave production for a mode that induces sleep. Delta waves production has, typically, a duration that is twice that of either the alpha or theta wave production. A second mode of operation sees longer pulse times for higher frequencies—between about 100 Hz and 500 Hz—associated with muscle stimulation.

- 1. A therapeutic electromagnetic field generator device comprising:
a field generating circuit containing at least one electromagnetic radiating element having a conductive track geometry having a multiplicity of tracks in which multiple adjacent side-by-side pairings of tracks conduct electrical current in opposite directions configured such that, for a relatively large electric field arising in the radiating element, component parts of a magnetic field produced by the radiating element at least partially cancel each other out and reduce an overall magnetic field associated with the relatively large electric field; a processor responsive to a control algorithm stored in memory, the processor configured to provide a control signal to the field generating circuit to cause the radiating element to generate: i) a base heartbeat reference; and ii) at periodic times, supplementing the base heartbeat reference with mutually exclusively generated frequency components between 0.5 Hz and 500 Hz; and wherein the electric field across the radiating element is between 200 V/m and 3000 V/m and the magnetic field is between 1 uT and 300 mT as measured at the surface of the radiating element.
- 14. A method of inducing a state of sleep of relaxation in a patient, the method comprising:
generating and treating the patient with an electromagnetic field from a radiating element, the electromagnetic field assembled from an electric field component and a magnetic field component, the electric field component having field strength of between 200 V/m and 3000 V/m across a multiplicity of conductors configured as a radiating element having a pattern in which adjacent conductors have contra-flowing currents and wherein the magnetic field component between 1 μT and 50 mT, as measured at the surface of the radiating element; and generating a base heartbeat reference; and at periodic times, supplementing the base heartbeat reference with mutually exclusively generated frequency components between 0.5 Hz and 500 Hz, inducing the state of sleep or relaxation in the patient.
