Some other Compensation Technology Applications

These are few examples of 180° phase shift applications used in different realms, such as: therapeutic, electromagnetic compatibility, electronic, active noise reduction, nulling light and electromagnetic bio-compatibility.

 

   Therapy

 

 

General:

"The body signal can in case of certain indications (acute illnesses, toxic burden) also be inverted (180. phase turn) and be directly sent back into the sick tissue. Hereby follows, however, no extinction of the pathological frequencies due to interference, but a disassociation thereof. This produces a local warning signal with the same immune reactions as a response to the irritation, as described above." [more information]

Fighting tinnitus:

This tinnitus sound is then reproduced and phase-shifted to produce sound cancellation therapy that is similar to noise reducing headphones and industrial noise reduction technologies. The sound cancellation therapy is then presented to the patient for a period of 30 minutes. [more information]

Electromagnetic Compatibility

Protecting MRI systems from the Electromagnetic Environment

Some permanent and resistive "open" MRI systems, as well as some actively shielded superconducting MRI systems, are sensitive to abnormal fluctuations in environmental magnetic fields caused by moving vehicles, trains, elevators, electrical transformers and other sources. Due to these interferences, many MRI site locations are rejected. Virtually every open MRI system has an integral magnetic field compensation system, but these systems may not offer sufficient corrective capability of the ambient magnetic fields. Some early active compensation techniques are not able to provide uniform performance over a wide frequency bandwidth and can only compensate for minor field variations.../.. Providing real time compensation of changes in the environmental magnetic field, the MACS allows MRI systems to be placed in locations previously rejected due to the presence of varying high magnetic fields. By reducing these fluctuations on the MRI system, image quality is maintained and defective scanning sequences are virtually eliminated. [more information]

Harmonic Cancellation

This distorted waveform rich in harmonics is not desirable to today’s electronics. One way to get rid of the harmonics is by phase shifting. If two identical waveforms are phase shifted 180° from each other, they will completely cancel  waveform becomes more sinusoidal. [more information]

Active Noise Cancellation

Noise pollution

Now, if you add two waves together that are going in the same direction, and if those waves are completely out of phase--that is, the peaks of one line up with the valleys of the other--then the amplitude or height of the waves cancel each other out. In the illustration above, the addition of the two waves will result in a flat wave or line in the middle. In this special situation, you would hear no sound. [more information]

Astronomy (Nulling Light)

Nulling Light

To be able to see a faint planet near a bright star an artificial (star) eclipse has to be created. This can be achieved by means of destructive interference of the light of two telescopes as shown in the figure on the right. If the light of telescope #2 is shifted by exactly half a wavelength (π phase shift) with respect to telescope #1, the combination of the two signals cancel each other out. This technique is called ‘Nulling’. [more information]

Electromagnetic Compatibility at biological level

Cellular Phone Bio-Compatibility

The phase shifting antenna captures the cellular phone wave (in phase) and emit an opposed wave (out of phase) to cancel at the biological level, the electromagnetic polluting wave emitted by the phone. [more information]
