Destructive Interference - Common Mode Rejection

The human body is the receiver. All signals to be filtered out. The fee would depend on whether the designer: 1) Understands the concepts involved and has the means to provide effective protection; 2) Is willing to accept the target's situation.

Sounds like you're looking for the basis of electrocardiograph and/or electroencephalogram reading electronics or one of the other bio-electrical signals. If not then you will have to consider what these signals will do to your desired pickup.

Thank you for your response. This is a civillian problem affecting the public at large involuntarily, so I don't believe there would be any restrictions as to a remedy. I'm not looking for a jammer or scrambler, as these are used by the military on the enemy, and would probably add to the source of the problem energy. They are also widely used in the commercial market, but at different frequencies and lower power levels. Analyze the source to a person, and cancel the incoming.

Good information. I'll take that into consideration when I reach the design phase.

If the human body is the receiver as stated in your other post, then there are two possibilities to consider. Either the body is acting as an antenna, or there is a device involved. If the body is acting as an antenna and there's no device, then the frequency of the impinging signals is in the resonant range, that is 3 Mhz to 3 Ghz. Your body height could be an indication of the frequency involved (1/2 or 1/4 wavelength).

If you can tell me what the physical effects are, I may be able to tell you whether it is likely body-antenna effects or device-induced. For example, do you have electric shock sensations, pain in the ankles only; do you have pulsing sensations etc. Be specific. Second, are the effects localized (or worse) in one building or place.

If you have any hyperthermia (overheating) and other physical symptoms on your head or neck, try wrapping with a soaked cold towel or facecloth for interim relief.

Tinfoil, shminfoil. They don't use tinfoil to shield yer precious cpu now do they. Why do they go to so much trouble, if tinfoil is good enough? What you want for your head is a proper housing made of metal, some antistatic foam stuff, and a fan unit of course, for cooling!!

Thank you for your response. I'm looking for something more effective.

Oh! ...And welcome to CR4.

Hope you enjoy yourself participating in tons of interesting and entertaining discussions over the life of your membership.

Use a tuned scanner to identify. Use a microcontroller to then automatically access circuits cabable of destructive interference, at the precise frequency, amplitude, and modulation of any frequency hopping. At millimeter wave and light frequencies, physics would come into play to identify the photons being used of alpha, beta, and gamma. I would use at least ten separate circuits to be sync-microcontrolled. A spectrometer would be necessary at the upper frequencies. This system would be only defensive in nature and protect the integrity of the individual. Quite an inexpensive project in retrospect. All design ideas are welcome.

They can easily work their way around any screen using lasers. They can easily penetrate any (lead) shielding or cage by computer subroutines that find an opening the size of a laser's bandwidth (about the size of a pin), and pour all power through it. They sector a surveillance area using a computer, zoom in on the target and penetrate any area of the body in this manner using a host of modulation types. How does one use destructive interference to cancel the sector. At short range, think of a full body scanner, metal detector, or CT Scanner. At longer range, think of infra-red imaging systems, any radar system, or GPS which pinpoints signals to your head (cell phone).

Any of those supposedly remedies mentioned maybe possible / true, but unless the OP releases or give more detailed specification for the given application plus related problems encountered, then every responses received are just going to be all guestimates, as in mine. In 30 yrs experience in research and the clinical world, it was found that unique trial -error solutions were implemented to every problems encountered as they're mostly limited and governed by the application's own limiting environment.

They have overcome most limiting environments through actual experimentation, upgrades, and implementation.

My 'gut' feel based on the limited information given is that this is still some sort of "personal signal shield" product for the public and that the 'inventor' is keeping his 'cards' close to his chest due to perceived potential patent issues.

I just want some more information, there isn't even enough given to make an educated guess!

Medical; Environmental. Thank you for your response. The technology you are speaking of had been developed in the 1960's, and the electrical grid of the area is used to transfer energy. The bio-telemetry systems you are speaking of had been developed to track wild or test animals way back in the '50's. They are much more sophisticated at this time. Sonar is used to track whales or fish because of its properties in ocean water. Sonar may also be used above water to track moving objects depending on the frequency response of the moving object and its direction and azimuth using mathematics performed easily by computers. For instance, study the physics of air traffic control systems.

John,

You suggest that the electrical grid of the area is used to transfer energy. What gives you the idea that this is the case? Is your comment based on actual data, or on hearsay?

Secondly, when you refer to "them" or "they" (in other comments), do you have any idea of the actual identity of the parties you are referring to?

Third, you mentioned in another remark that lasers are involved. I did hear a rumor a couple of years ago, about a criminal or terrorist group using lasers. That is a matter of interest to both police and military, and presumably pursued by them, however I did not hear anything further about it. What makes you certain that lasers are being used in the manner you describe? Do you have any data to support the hypothesis that lasers are the cause of the effects?

It's common knowledge. You can scan the Internet under these terms or questions, and you will find an enormous amount of information about these subjects.

John, there's no point in believing "information" that isn't supported by data. I think the point of many responses to your question here has been, that you need frequency and amplitude data in order to solve the problem. "Common knowledge" that isn't backed up by data is no good. Things are not always what they seem, people are deceived, and even sincerely believe things that are not true. Do you want the facts or not?

With respect to the grid, I would recommend that you talk to engineers at the power company. These are honest and decent folk whose job is to ensure safe power delivery; they have test equipment and they will test your home connections, near by transformers, etc etc. and let you know what they find out.

I don't know about lasers and what the technical capabilities and limitations are. I know a point source is involved: I don't know about range or targeting capability. If you get the specs on the equipment, you can then decide whether it is feasible and possible or probable cause. I'd be interested in hearing what you find out.

I do know about current medical research devices and I would not rule this out on the basis of your description of effects. These devices have weapons capability, particularly when the design uses an external transmitter for the stimulus pulse train. (implanted batteries/IPG would run down; also tend to be bulky and easy to detect). The basic electrode can even be simple enough to be homebrew, although I doubt this is necessary considering what is readily available from industry with little or no oversight or regulation. Don't expect medical personnel to cooperate with a request to examine for devices that, if found, would implicate their own industry (or even their partners) in a crime. A CT can detect devices but there has to be explicit direction given as to what type of device is involved and where situated, otherwise it is useless.

I recommend that you get familiar with the signals environment, do some monitoring and testing and proper data collection, then assess and decide what type of technology is involved.

Thank you for your opinion of some debunking, and some advice. I'll keep you posted.

See comment #23.

Radars are jammed by different methods through the sidelobes, which work best depending on the type of system being used. Empirically, I've gone to depths of about 10 miles into the earth's crust in the U.S.A., and it doesn't interfere with their systems. After my own research, they can penetrate even much deeper with claims reaching to the earth's core. This offers no protection. The reflectors and phased array antenna designs on stealth aircraft confuse the other radar into thinking it's not where the radar says it is. It doesn't make it completely invisible. There is a point using the military black paint, and thick iron shielding of at least 3 inches thick. You can paint your house with stealth paint, but it still shows up on infra-red systems, and offers little protection to incoming (it absorbs just certain wavelengths). Phased array antenna systems can be used on the target's behalf to confuse the incoming, in conjunction with frequency hopping techniques and various multiplexing. Why not use about ten wide bandwidth receivers multiplexed by a microcontroller to lock on to the incoming and barrage cancel around the person at close range. It's the integrity of the person we want to protect.

Frequency counters can give the basic bandwidths to design cancellation circuits for.

They also make a virtual environment out of your environment on their end, and can remotely do whatever they want in your sector. For instance, it is known that they can even perform surgery in this way from a remote location(s). Again, lock on and barrage cancel the incoming.

John, with regard to the lasers, I admit I have no data or technical information about them, but I strongly suspect you and/or others are deceived. Simulations of remote surgery (the illusion of it) can be done with medical devices for a fact, and I think the technology is much more available than the laser capabilities you speak of. How big and conspicuous would the laser source have to be, to penetrate deep underground? (I don't know, but someone on CR4 should be able to answer) Could it be hidden at all.

The frequency band for devices obviously is not the same as lasers, and I really do urge you to look for medical telemetry signals in the environment before you assume that some obscure, unknown, or unlikely super-powerful technology is responsible for these effects. Get yourself a few inexpensive probes for starters, with different frequency ranges, a small pre-amp and a recording machine, and monitor the incoming when someone is suffering these physical effects. You can analyze the recorded signals afterwards. Incoming device telemetry would very likely be in frequencies between 1 Mhz and 100 Mhz, so a 1 Mhz-1Ghz probe is useful to see if there's anything identifiable as device telemetry or something prominent that's suitable as camo (video sync pulse or DECT for example). A probe like this can also be used with a DMM to pinpoint sources or measure high levels on the body indicating a device location (localized pain and swelling is a physical sign). And speaking of video, the off-the-shelf surveillance gear is mostly below 1 Ghz so if someone is watching the misery you will pick that up too, although it depends on your signals environment how easy it is to pick this out from legitimate activities. The urban/industrial environments are bound to be difficult. In a more rural home you may even pick up "their" communications and get an idea of who "they" are and how they are making the money out of this. You will need narrow band select technology if you want a good recording of any individual signal, although you can zero in on a strong signal fairly decently by adjusting the position of the probe and its cable (acting antenna).

The concept of locking on and cancelling with an opposite waveform is only feasible if you know what signal is causing the trouble. Is it possible "they" want you to think or say it is lasers when it is not? How will you get the data to find out whether it is or is not lasers.

For shielding device telemetry - typically pulse trains or "HFAC" type signals - you're best to go for a worst case scenario - the lower range and longer wavelength requires a much longer strip of shielding material, and you might try combining with a layer of RF absorbent material and fold it up to cover the affected body area. It must be grounded or frequently discharged by grounding. Absorbers are better than conductors when next to the skin - you don't want to be in contact with conductive material if there's a receiver on you. Designs that reflect and absorb - like the classic ear protectors for working with machines - can cover a device if the location is known and should provide relief from a localized device source. Pulsed signals go through the classic 'faraday' shielding readily, so choose the highest rated material you can find or afford for the frequency range. For people with few resources, as I mentioned before, a soaked wet cloth that is thick enough also has a shielding effect (maybe the best especially if there's hyperthermia). An iron prybar or a piece or rebar of the right length will also absorb a lot of incoming signal if the position is right and it can be laid on the skin (good ol cold iron).

Wrapping a wet towel around your head has absolutely no shielding capability. Wrapping inductive cores around your body, using tin foil hats, and using magnets have absolutely no effect whatsoever. High-Technology analysis and precise cancellation of the bandwidth spectrum(s) being used is the only way.

When systems using frequencies in the millimeter and light spectrum, the modulating electrons slow down or stop. However, fiber optics can modulate huge amounts of information on a light beam the size of a pin enormous distances at normal communication modulation frequencies and types. Systems are designed around this principal of physics. Inert gases of specific wavelenghs are used to identify the light spectrum. I think that the bulk of incoming is from low budget or lower tech stalking groups who are very well organized and use conventional communications techniques.

The groups that actually use electron gun weapons, plasma, lasers, and infrared or thermal imaging techniques are at a higher level and utilize the lower groups described above.

Yes, a frequency counter is the type of test equipment used to get frequency information about the signals of interest. You really need that information to design shielding and/or track to source, for that matter. A good frequency counter is not cheap to buy or to rent: shop carefully. I bought one of the Spectran series up to 6 Ghz made by Aaronia, way better than the Mitronics (I actually got some useful data) but I returned it because some features didn't work as expected - the demodulator sucked because it had the same resolution apparently as the counter - to 1 Mhz only. They have a lot of new models since then with extended ranges.

I don't even know if there are frequency counters for lasers.

Wouldn't a spectrometer be a frequency counter or spectrum analyzer for lasers?

Definition of spectrometry in the second paragraph here.

There are a lot of different instruments with similar (or different) functions and names. "Frequency counter" is the term that I know of, for an instrument to identify the frequency of a signal in a range usually below the visible light range.

In the visible range or above, spectrometers/spectrophotometers are used mainly to identify materials. (see portable RAMAN for example, which itself uses a laser to obtain the wave information/ signature of a material).

I did some more reading on lasers. Afaict the only lasers capable of the described remote effects are FEL types , which are of necessity large heavy gear which is both costly and conspicuous to use because of its high power consumption. The only place you could possibly hide a FEL laser weapon is in plain sight. A covert installation would be immediately busted - grow ops fhs are identified and busted because of power consumption! The power requirements of a FEL laser are far greater and an industrial pretext for the FEL would be necessary to justify such consumption. In fact you can't buy the necessary gear for FEL without the government being aware of it, it is a radiation hazard and the installations are both known and regulated.

As a means of "stalking" or even for human/organ trafficking which is a profitable crime, a FEL laser is completely impractical compared with other readily available, cheap, multi-target means of simulating surgical pain and other physical and sensory effects (devices). You would need a jumbo jet to move a FEL around. It is only capable of acquiring one target at a time. It would cost millions to follow one target for one afternoon. A human slave, value of organs included, may be worth a million all told but not millions per day after day.

If a FEL installation was really intended as a weapon and using some legitimate pretext as cover, it would only be feasible if there was a single, fixed, high value target (White House or equivalent) in range. It shouldn't be too difficult to find out if any medical or research FEL have or do not have the capability to acquire a target outside the facility's walls. I would expect that they are designed not to have this capability, and this would completely rule out the unlikely possibility that a FEL laser is involved in any of the reported cases of "remote surgery" or simulations of surgery experienced by the target as real. It would also rule out the possibility that such facilities would be taken over by terrorists for weapons purposes - a risk that I expect Homeland Security or other police agency will have considered and investigated in the USA.

AFAIK the portable lasers that might be used for homebrew weapons (a) produce visible light/beam (b) produce measurable and obvious damage such as blindness, burns. This is not consistent with the effects described by the OP.

Good information. Depending on the sophistication and funding of the stalking group, high-level cancellation may or may not be necessary. A good starting place for development would be with conventional electronics and communication systems. Higher-level torture use arbitrary waveform generators that modulate around a person's head looking for an opening in any shielding. Once an opening is found, full power is pumped in using very tiny bandwidths as the person is simultaneously surveilled by another system. The cowards rarely work alone.

John,

The rule of thumb for organized crime is "suits on top and in the background: gangs/bikers/thugs in the frontlines". Read about organized crime in these CISC reports and you will find a good fit for what seems to be going on.

General characteristics to keep in mind: these organizations are:

- covert. Expect to be deceived! Get some data and expert advice before you jump to conclusions about technical matters, because wrong assumptions will tend to damage your reputation as a believeable and reasonable person.

- profit driven. I have heard stories like yours that use terms like "stalking" and "electronic harrassment". afaik the actual revenue streams from this activity are better described as human trafficking -which the victim is not to know.

- device is a great fit for the existing infrastructure and networked activities of organized crime. ".. conventional electronics and communications systems" yes, look for telemetry in the unlicensed ISM bands where it will go unnoticed. Look for surveillance in the off the shelf gear bands. Look for radiocommunications in licensed network bands. If you can afford it, get a good receiver with narrow band select features so you can zero in and record what is going on.

- if device is involved, physical access to your person is also involved. Bolt your doors.

I would like to stick to the technical aspects of the problem to defeat it. The politics of it you can have. Innocent human lives are destroyed for no reason. That is all we need to know.

Yes. They usually go way up in cost depending upon the sophistication of the instrument, its capabilities, and its intended application.

Hi, Lo Volt!

No. Check some reliable online source to find out what a spectrometer does.

Thank you for your input. I'd like to hear more.

Thank you for your response. I've been designing and testing my own op amp and communication circuits/systems and those of others for the past three years. They are easily bypassed.

Are you screening the circuits to the ultimate degree ?

I had problems with a lighting rig inducing noise into an audio circuit and just balanced lines cured the problem and the circuit was not even screened and this was the only one of these audio circuits out of thousands that reported any problems.

The circuit is my copywrite I am afraid.

Also fitted a faraday cage around a very high gain circuit with power supply also screened and it was picking up the signals I wanted.

I appreciate the information, but this type of circuit wouldn't work for my application. While working on computer boards in the past, they have pinpointed a laser from a remote location and have fried a hole in an IC chip while watching. Again, conventional shielding does not work for the application I'm working on. However, at the (very) low-level stalking group application, a circuit like yours might block some of it, possibly. All information like yours is or can be helpful. I would encourage anyone to add to this thread. Thanks again.

That would be a good start in theory. Thank you for the information. Amplitude/power, phase, frequency, and modulation would all need to be cancelled. Very high power levels are used by very sophisticated modulation techniques arriving from one or more transmitters. All factors above are changed constantly depending upon the aspect of mind control being induced, so tracking would be a problem.
