Device Description The Resonator is a device that generates an electromagnetic field intended to be applied to an individuals’ entire body, or to a specifically targeted portion of an individual’s body, for the purpose of therapeutic intervention of disease or illness. The Resonator includes a PC/laptop computer that controls a magnetic therapy driver enclosure that includes a signal generator and attenuation circuit for producing a signal of predetermined amplitude and of predetermined frequency to generate a desired extremely low level magnetic field. The field is produced by helmholtz coils which are operatively connected to the magnetic therapy driver. Thus, this device is used to derive a magnetic flux density B which is generated through the helmholtz coils. The generator is capable of one millivolt to four volt amplitude. The attenuator is capable of attenuation from about 10 milligauss to about 1 attogauss by combining the generator range and attenuator selection ranges. The structure supporting the helmholtz coils is sized such that the helmholtz coils can range in diameters from 18 inches to 7 feet, depending on the target to which the field is to be applied. (See Below).  The Resonator is a device that is controlled by a PC/laptop that is connected to a magnetic therapy driver enclosure that contains a signal generator in cooperative operation with an attenuator circuit to produce a magnetic field. (see figure 1., above) A signal generator provides the “signal in” while the attenuator circuit is prepared for a helmholtz coil that is 7 feet in diameter. The resonator system is designed to create a homogeneous, isotropic magnetic field in the picoTesla (pT) range, most specifically from 1 pT to 99 pT and a frequency range from .01 Hz to 50.0 Hz (specifically for this trial); and utilizing an electrical current thereby producing a changing magnetic field in between the Helmholtz coil system. The patient may be sitting or in a supine position between the coils. The term resonance used with respect to this device refers specifically to “amplitude” resonance. Field polarity changes are to be used for the system under discussion, and limited to .1 Hz to 50.0 Hz. Signal Generator and Attenuation circuit board The board uses an Atmel AT32UC3A0512 µprocessor with an Ethernet port, USB, and SPI interfaces. The SPI interface is primarily used to communicate with the Little Nik Controller-Attenuator. The frequency generator, AD9832, the DAC’s, AD5680, and the relay drivers, MAX4820, are parts on the board and all use the SPI port addresses as outlined in the specifications document. There is a PC/laptop running user interface software (GUI) that is connected to the µprocessor via an Ethernet interface. The signal generator produces the precise amplitude for the desired magnetic field. The generator is capable of 1 millivolt to 4 volts amplitude generation into a 1000-ohm load termination. The attenuator uses the signal produced by the generator to drive the coils of the resonator. The attenuation circuit uses the signal produced by the generator to drive the Helmholtz coils. The circuitry is custom designed to provide impedance matching to the generator and selectable attenuation of the signal. The attenuation range is from 10 milli gauss to 1 nano gauss by combining the generator range and the attenuator selection ranges. Circuitry within the unit provides for continuity verification after assembly of the system to confirm a complete circuit for the signal generator. The magnetic fields are produced by simplified Helmholtz coils. The coils are 7 feet in diameter with a separation of 3 ½ feet. The coils’ uniformity, density, wire gauge, current and voltage were determined by the requirements to produce the required magnetic fields as defined by the foregoing signal parameter’s intended use. The system to be used in this study includes a fiberglass platform with steps for the subject to walk up and mount the platform. Handrails serve to provide stability as the subject walks up the steps to the platform. The coils are fiberglass rings with copper wire wound around an end groove. Because of the size of the coils, a support connects one coil to the other coil, to provide stability, and the coils are mounted onto the platform through coil supports. No ferrous metals are used in the construction of the resonator. |
