The example mode partition devices are shown in greater detail in FIG. 3, FIG. 4, and FIG. 5. The mode partition devices are merely resistance networks which produce 1 through N output voltages which are predetermined divisions of the input original from the acoustic filter associated with the mode partition device.

FIG. 3 shows a mode partitioning device wherein several outputs are associated with each series resistor 30.

In the embodiment depicted in FIG. 4 there is an output associated with each series resistor only, and thus there are N series resistors, or the same number of series resistors as there are outputs. The values of the resistors in the mode partition resistor network are determined in accordance with the magnitudes of the frequency component from the acoustic filter bank 12 which is required at the summation point 19 or the gain control line for amplifiers 20. The microwave amplifier bank 18 Consists of: plurality of microwave oscillators 1 through N each of which is connected to an amplifier

20. Since the amplifiers 20 are gain controlled by the signals at summation junction 19. the magnitude of the microwave output is controlled by the mode control matrix outputs Fl through F. In the preferred embodiment there are 24 amplifiers. The leads from the microwave oscillators I through N to the amplifiers 20 are shielded to prevent cross talk from one oscillator to the next, and to prevent stray signals from reaching the user of the hearing device. The output impedance of amplifiers 20 should be 1000 ohms and this is indicated by resistor 21. The outputs of amplifiers 20 are all connected to a summing junction 22. The summing junction 22 is connected to a summing impedance 23 which is approximately 50 ohms. The relatively high amplifier output impedance 21 as compared to the relatively low summing impedance 23 provides minimization of cross talk between the amplifiers. Since the amplitude of the microwave signal needed at the antenna 24 is relatively small, there is no need to match the antenna and summing junction impedances to the amplifier 20 output impedances. Efficiency of the amplifiers 20 is not critical. Level control of the signal at antenna 24 is controlled by pick off 25 which is connected to the summing impedance 23.

In this manner the signal at antenna 24 can be varied from 0 (ground) to a value which is acceptable to the individual. The antenna 24 is placed next to the subject’s head and in the region of the subjects auditory cortex 26. By placement of the antenna 24 in the region of the auditory cortex 26. the microwave field which is generated simulates the microwave field which would be generated if the acoustic sounds were perceived with normal hearing and the auditory cortex was functioning normally.

In FIG. 2 A there is shown a second embodiment of the microwave radiation and generator portion of the hearing device. In this embodiment a broad band microwave source 50 generates microwave signals which are feed to filters 52 through 58 which select from the broad band radiation particular frequencies to be transmitted to the person. As in FIG. 2 the amplifiers 20 receive signals on lines 19 from the mode control matrix. The signals on lines 19 provide the gain control for amplifiers 20.

In FIG. 6 there is shown a modified microwave hearing generator 60 which includes a mode partition resistor divider network as depicted in FIG. 5. Each of the mode partition voltage divider networks in this embodi ment are individually adjustable for all ot the resistances in the resistance network.

FIG. 5 depicts a voltage division system wherein adjustment of the voltage partition resistors is provided for.

In FIG. 6, the sound source 62 generates audible sounds which are received by the microphone of the microwave hearing generator 60. In accordance with the operation described with respect to FIG’S 1 and 2. microwave signals are generated at the antenna 10 in accordance with the redistribution provided by the mode control matrix as set forth in FIG. 5. The sound source 62 also produces a signal on line 6-4 which is received by a head phone 66. The apparatus depicted in FIG 6 is used to calibrate or fit a microwave hearing generator to a particular individual. Once the hearing generater is adjuasted to the particular individual by adjustment of the variable resistors in the adjustable mode partition portion of the hearing generator.

A second generator may be built using fixed value resistors in accordance with the adjusted values achieved in fitting the device to the particular subject The sound produced by headphone 66 should he the same as a sound from the sound source 62 which is received by the microphone 10 in the microwave hearing generator 60. In this way, the subject can make comparisons between the perceived sound from the hearing generator 60. and the sound which is heard from headphone 66. Sound source 62 also produces a signal on 68 which is feed in cue light 69. Cua light 69 comes on whenever a sound is emitted from sound source 62 to the microwave generator 60.

In Fig. 7 there is shown a modified microwave generator which may be used to determine a subject’s microwave mode frequencies. In this device the acoustic filter bank and the mode control matrix have been removed and replaced by voltage level signals generated by potentiometers 70. Also included ar a plurality of variable frequency oscillators 72 which feed microwave amplifiers 74 which are gain controlled from the signal generated by potentiometers 70 and pick off arm 76.?

This modified microwave hearing generator is used to provide signals using one oscillator at a timi. When an oscillator is turned on. the frequency is varried about the estimated value until a maximum acoustic perception by the subject is perceived. This perception however may consist of a buzzing or hissing sound tat rather than a tone because only one microwave frequencies being received. The first test of perception is to determine the subject’s lowest modal frequency for audibility. (M= 1). Once this modal frequency is obtained. The process is repeated for several higher modal frequencies and continued until no maximum acoustic perception occurs.

Another method of determination of a subject’s modal frequencies is through anatomical estimation. This procedure is by measurement of the subject’s cephalic index and the lateral dimensions of the skull. In this method, the shape is determined in prolate spheroidal coordinance. Purely anatomical estimation of sub ject’s modal frequencies is performed by first measuring the maximum lateral dimension (breadth) L FIG. 1, of the subject’s head together with the maximum dimension D (anterior to Posterior) in the medial plane of the subject’s head. D is the distance along Z axis as shown in FIG. 10.

The ratio L/D, called in anthropology the cephalic index, is monotonically related to the boundary value E0 defining the ellipsoidal surface approximating the interface between the brain and the skull in the prolate spheroidal coordinate system. E0 defines the shape of this interface; E0 and D together give an estimate of a, the semi-focal distance of the defining ellipsoid. Using E0 and a, together with known values of the conductivity and di-electric constants of brain tissue, those wavelengths are found for which the radial component of the electric field satisfies the boundary condition that it is zero at E0.

These wavelengths are the wavelenghts associated wi ith the standing waves or modes. The corresponding frequencies are found by dividing the phase velocity of microwaves in brain tissue by each of the wavelengths A subject’s microwave modal frequencies may also be determined by observing the effect of external microwave radiation upon the EEG. The frequency of the M equal I mode may then be used as a base point to estimate all other modal frequencies.

A typical example of such an estimation is where the subject is laterally irradiated with a monochromatic microwave field simultaneous with EEG measurement and the microwave frequency altered until a significant change occurs in the EEG, the lowest such frequency causing a significant EEG change is found. This is identified as the frequency of the M= 1 mode, the lowest mode of importance in auditory perception. The purely anatomical estimation procedure (FIGS. 8, 9, 10) is then performed and the ratio of each modal frequency to the M 1 modal frequency obtained. These ratios together with the experimentally-determined M – I frequency are then used to estimate the frequencies of the mode numbers higher than 1. The prolate spheroidal coordinate system is shown in FIG. 9. Along the lateral plane containing the x and y coordinates of FIG. 9. the prolate spheroidal coordinate variable 4 (angle) lies FIGS. 9 and 10. Plots of the transverse electric field amplitude versus primary mode number m are shown in FIG. 11.

The equation is

The “elevation view” FIG. 12, of the brain from the left side, shows the primary auditory cortex 10. The isotone lines and the high frequency region are toward the top of 100 and the low frequency region toward the bottom of 100.

The formula I, set forth below is the formula for combining modes from an isotone line at ø= øj being excited to obtain the total modal field at some other angular location ø. For this

formula, if we let J= 1 (just one isotone single frequency acouistic stimulus line), then it can be shown that ALL modes (in general) must be used for any ONE tone.

FIG. 13 shows the resulting total modal field versus angle ø for source location ø at 5.25 degree, 12.5 degree, etc. With reference to the set of curves at the left top of this figure. A spacing of approximately 7.25 degree in ø’ corresponds to a tonal difference of about I octave. This conclusion is based on the side lobes of pattern coming from ø=5.25 degree, etc. The total filed (value on y-axis) falls considerably below the top curves for source locations well below 5.25 degree (toward the high acoustic stimulus end) and also as the source of frequency goes well above 10 degree frequency end) ø is plotted positive downward from the (at lateral location as indicates in FIG I 11. Resistor weightings are obtained from the (unreadable word) (m[ø -øj]). Formula I. The scale between acoustic frequency and ø must be set or estimated from experiment. Approximately 5.25 ± 1 degree corresponils to a tonal stimulus at about 2 khz. (the most sensitive region of the ear) since this source location gives the highest electric field amplitude.

The apparatus of FIG. 7 may also be used to determine values for a hearing device which are required for a particular subject. Once the modal frequencies have been estimated, the device of FIG. 7 which includes variable microwave oscillators may be used to determine values for the oscillators which match the subject, and to determine resistance values associated with the mode partition devices of the mode control matrix. In FIG. 7 manual control of the amplifier gain is achieved by potentiometers 76. In this manner the amplifier gains are varied about the estimated settings ror an acoustic tone stimulus in the region of two thousand Hertz (2 khz) until maximum acoustic perception and a purest tone are achieved together. The term purest tone may also be described as the most pleasing acoustic perception by the subject.

This process may be repeated at selected .frequencies above and below 2 kHz. The selected frequencies correspond to regions of other acoustic filter center frequencies of the subject. When modal frequency (oscillator frequency) and gain set values (setting a potentiometer 76) are noted, it is then possible to calculate fixed oscillator frequencies and control resistor values for the adjusted hearing device for this particular subject. In the event the subject has no prior acoustic experience, that is deaf from birth, estimated resistor values must be used. Also, a complex acoustic stimulation test including language articulation and pairs of harmonically related tones may be developed to maximize the match of the hearing device parameters for those of this particular subject.

Typical components for use in this invention include commercially available high fidelity microphones which have a range of 50 Hz to 5 kHz with plus or minus 3 dB variation. The audio filters to be used with the acoustic filter bank 12 are constructed in a conventional manner, and have Q values of about 6. The filters may also be designed with 3 dB down points (½ the bandwidth away from the center frequency) occurring at adjacent center frequency locations. The diodes 17 in the mode control matrix which provide isolation between the mode partition circuits are commercially available diodes in the audio range. The microwave oscillators I through N and the microwave amplifiers 20 are constructed with available microwave transistors which can be configured either as oscillators or amplifiers. Examples of the transistors are GaAsFET field effect transistors by Hewlitt Packard known as the HFET series or silicone bipolar transistors by Hewlitt Packard known as the HXTR series. All the cable between the oscillators, the microwave amplifiers, and the antenna should be constructed with either single or double shielded coaxial cable. The antenna 24 for directing microwave signals to the audio cortex 26 should be approximately the size of the auditory cortex. A typical size would be one and one half CM high and one half to one CM wide. The antenna as shown is located over the left auditory cortex. but the right may also be used. Since the characteristic impedance of the brain tissue at these microwave frequencies is close to 50 ohms, efficient transmission by commercially available standard 30 ohm coax is possible.

In 1989, James C. Lin wrote Electromagnetic Interaction With Biological Systems which deals with transmitting ideas and words via electromagnetic waves. Brief cases, stereo speakers and boxes are some of the disguises that the CIA has been caught using to hide their ELF microwave emitters that plant thoughts in people. One victim who spent time talking to Fritz Springmeier reported how they had repeated tried to trick him into going to free hotel rooms and other traps, where they tried to bombard his head with the idea that he should sell drugs. He cleverly dismantled their devices which they hid in the ceilings and other locations in these rooms to protect himself from the thoughts they were tryin~ repeatedly to beam into his head. He was on the run as a fugitive to protect his mind. Naval Intelligence and other groups have conducted research into ELF waves upon the human body and mind. Some of the many things that can be done to the human body and mind with ELF waves include:

  1. put a person to sleep
  2. make a person tired or depressed
  3. create a feeling of fear in a person
  4. create a zombie state
  5. create a violent state
  6. create a state of being sexually aggressive
  7. change cellular chemistry
  8. change hormone levels
  9. inhibit or enhance M(RNA) synthesis/processes
  10. control the DNA transaction process
  11. control biological spin and proton coupling constants in DNA, RNA & RNA transferases.

Unfortunately for us humans, ELF waves can penetrate almost anything. The U.S. Military has built a Ground Wave Emergency Network (GWEN) all over the U.S. with several hundred 300-500′ GWEN towers that broadcast a very-low-frequency wave (VLF) for mind control of the American public. A single GWEN tower can broadcast up to 300 miles in a 3600 circle. Plus 8 secret powerful
