CA2441882C - Underwater magnetic field communication system - Google Patents

Abstract

I feel there is a need for submarines to communicate effectively with other submarines ships and airplanes. The same invention can also be used for trapped miners to communicate with their rescuers.
If for a moment we oversimplify it, the invention is basically a radio transmitting and receiving antenna system that works under water as well as above it and attaches to standard radio transmitting and receiving equipment. Its purpose is primarily that submarines can communicate with other submarines, even robot submarines, ships, as well as aircraft flying overhead or even land based stations.
Whether the submarine is submerged or surfaced should make no difference in transmission or reception of radio signals except for a slight difference in the tuning of the transmitting system. The system also works underground up to a point depending on the distance and radio frequency used. This is basically in a nutshell what it's all about.
Unlike other systems in use at present, which work on sound which is plagued by echoes, or the electrical conductivity of water that limits its use to water only, or in some cases in one way transmission only, my system has no such obstacles and even can be used for TV
transmission.

Description

Disclosure How does the magnetic field transmission system work?
Although any other name could have been used. magnetic field transmission simply implies transmitting with a magnetic field instead of an electromagnetic wave.
The build up of the magnetic field is not subject io the speed of light as a wave is, but depending on the circumstance in general is faster or higher, in other words it is not directly linked to the speed of light. but depends on the speed with which the magnetic force lines build up and it can as a result also penetrate substances like water.
A simple way to explain how the system works, is to compare it to an electrical transformer, or better yet a transformer with the iron core left out, in other words an air core transformer. The more the primary winding and secondary winding are spread apart or separated from each other, the less energy is transferred to the secondary winding.
However one has to keep in mind that we are not interested in how much energy can be transferred, only over what distance an intelligent signal can be transmitted in this manner.
Iiasicalty the transmitting coil acts as the primary winding and the receiving colt acts as the secondary winding. In simple teens. the principle is the same as used in an electrical transformer, the transmitting coil generates a magnetic field which in turn induces an emf (electromotive force) in the receiving coil, in other words the alternating magnetic field is turned back into an electrical current again which carries the information.
From a scientirc point of view the principle in itself is nothing new and is used in various ways, except that I have made use of this well known principle and developed a communication system for submarines which as yet has not been made use of by others.

'The embodiment of the invention in which an exclusive propertlv or privilege is claimed are defined as follows."
Description of the device.
1'he device is an electrically ( plastic or rubber) insulated metal ring of copper or aluminum ( Drawing hid l.) which is open ended one side and hattn electrical capacitor connected across the ends of the metal ring. It has also ~r short wire connected tco each end of the rind which then feeds tco a coax cable or conventional radio transmitter output circuit dire~ctly. ('l'he radio transmitter is not part ctf my invention. otlly the device is my invention .
which like an antenna attaches to the transmitter. ) For best results 1 have t<aund that the coil should be approximately between 1/30 to II40 of the wavelength ofthe trap smittcr frequency. An exact slze is IIOI critical since it is cennpensatc:d for by the capacitor.
y(>ne could define the device as an underwater antenna system. however one has to keep in mina that regular transmittir~~ and rec~ivin~ antennas do not work under water and this is basically where the stnnlarity ends.
~lyrc~rtlar transmitting antenna generates an clcctroma~netic w -avt which propa~rttes with the speed of light and is composed of a ma~nctic kicld and an electrostatic field. 'theoretically an electroma~nctic wave continues on forever except that its intensity drops bclouv the llotse level where it canlu~t be detected any more.
My device ~!eneratcs a pure rna~nt;tic lied only and as a result is not subject to the same principles such as the speed of light. Furthermore it suppresses the electrical component which is necessary to ~~enerate a standard radio wrave. En general the system call he mounted Leith an appropriate support structure almost any place sufticientlv 1i-tr enough away from the ship's hull What makes the transmitting device work under water?
From a theomtical point of view a magnetic told whether continuous or alternating is not governed by the same principles as a wave is. E'hc build up of'a magnetic field could be considered instantaneous. hut it is nevertheless subject tc~ the impedance of the coil. or in this case the coil and capacitor which so to speak ~ovtrns its speed.
I't.u-tllermorc the magmtic field lines always titrm a clc:tscd circuit, regardless how- tar they reach. tht:v must alw~rvs return to their point crf c7ri~in. Near the coil the magnetic lines of t«rcc are very densely packed. but the farther away we move ti-om the cul the less dense the field lines become.
Et is a well known fact that the E=.arth's magnetic field penetrates water.
earth or soil and even rock. Likewise an alternating field even at the radio frequency rant;c also penetrates water and so fbrth. Metals and elcctricallv conductive 111aterlals cannot he penetrated bv_ alternating magnetic tielcts hec~tusc an oppclsin~ current is set up that prc:vcnts penetration.
My experiments have sh«wn very ~.ood results in water, salt water has only shown a slight attenuation of the si~.nal.

On what grounds do I call it an invention, when it's nothing more than a coil of wire and a capacitor ?
llntortunately this may be a decision which I have net control over. but let me start out by saying that an invention is not rated by how complex it is. but rather on what it does. I'here are no underwater radio antennas that I know oi~. even so. my system could also be rejected on the a ssumptiora that there is insui~ficient proof that it really works.
IW t let me say in my own defense. if f vverr to put the tuansmittin~; system into a black box so to sloeak and dive a demonstration, everyone seeing it would definitely call it an invention, because there is nothing on the market like it. I Iov'~cver the moment 1 open the box there is this hid disappointment and son neone will say "You mean this capacitor and piece oFwirc is your invention'' So which part did you reallv° invent the capacitor or piece of'wirc'?~~ My answer mould have to he: neither, it's only the way the:v are hooked to~ethcr the sire oi~lhe capacitor and the prcaper diameter of the coil.
'I o dive an example. the telescope vas invented by a young boy who one day exclaimed, "'It.
I hold these two lenses like this it brings the church steeple clc>ser.~" Mans I.ippershee wamit~ed this very closely and as a result the° telescope was invented. We rnrry ~.ive Oalilleo the credit for inventing the tc:lescope_ but the: credit should ~o to the boy. even though he did not grind a Ions much less invented the Mass lens. I'he vvay the two are put together is what makes the invention.
1'o give an other example a tuned electrical line can be nothiry more than a bent piece of wire or metal strip on a circuit board. vet it contr~c~Is the t'reducncv ot'an oscillator or acts as a tuned circuit to select the: ii-eduency oi~a radio receiver. l~:vcn though it is nothing tnorc than a bent piece ot'wire it is still an invention since it replaces the comnum resonant circuit.
In my case we could simply call the mire ioc>p ~md capacitor a ryular resonant circuit and not regard it as an invention at all, however we hay a to keep in mind that ahoost any length of wire wish the proper capacitor will transmit a signal when hooked up to <r radio transmitter, but unless it is the proper Sire it mill not etticientlv ~.e-negate a pure ma~nctic field that sutlicientlv penetrates water. I'he invention basically lies ivn tht: leryth of wire and the way it is used, but .
most of all it lies in the idea to make use oH~ margnctism instead of a ne~r.rlar radio wave. h'or example the Marconi or hertz antenna are notl~in,,~ more than wires oCpropcr length, vet they hay°e been patented. ' .
W'hcn reviewing my application I hope you take into consideration the ~~ood it can do or the lives it can save in the t~uture. I also hope that you do not.judge it on the:
basis that the individual parts do not m~rke an invention. but on the (act that when all the individual parts come properly=
together nothing of this kind exists as vet, and that is what makes it an invention 1 believe that the public ~rnd c~urJarmed forces nerd this invention. 1 do not have the means to develop my invention on a lame scale such as ccymmunicating with submarines on floe bottom o(~the ocean. I have tried to approach several peopl. but so lug ~vervthin~ 1 said has fallen on deal'ears. 1 am not interested in any financial lain, but without a patent I
cannot bring the idea to life.
