Internal Communication System - ICS
This proposal is for an auditory internal communication system. Such a system encompasses the following parts: (1) Cochlea implant; (2) radio transmitter implant into the cochlea; and (3) microscopic microphone implant into the vocal cords. These will be explored in the more detail in the description portion of this proposal.
This device is designed especially to be used for covert operations. As it is the target customer of this device are the following groups domestically and internationally:

Description of Proposed System
A. Cochlear Implant
By implementing a pre-existing technological breakthrough device developed by D. William House of All Hear, Inc., a "cochlear implant" will be done on the human subject. Such an implant causes a stimulation of sound to the spiral ganglion cells by using electronic signals emitted to the basal coil of the cochlea.

The "cochlea," is shaped like the coiled shell of a snail. Inside, it contains a bony core and a thin bony shelf (spiral lamina) that winds around the core like the threads of a screw. The shelf divides the bony labyrinth of the cochlea into upper and lower compartments. The upper compartment, called the "scala vestibuli," leads from the oval window to the apex of the spiral. The lower compartment, the "scala tympani," extends from the apex of the cochlea to a membrane-covered opening in the wall of the inner ear called the "round window." The round window is actually situated below and little to the back of the oval window, from which it is separated by a rounded elevation, the "promontory." The membranous labyrinth of the cochlea is represented by the "cochlear duct" (scala media). It lies between the two bony compartments and ends as a closed sac at the apex of the cochlea. The cochlear duct is separated from the scala vestibuli by a "vestibular membrane" (Reissner's membrane) and from the scala tympani by a "basilar membrane." The basilar membrane extends down from the bony shelf to form the floor of the cochlear duct.
B. Radio Transmitter to be implanted into the Cochlea
On the base of the cochlea, a miniscule radio device will be implanted to act as the transmitter of communication. This will act as the electronic signals that is required to stimulate sound to the spiral ganglion cells of the Cochlea.

Radio waves occur naturally in space. When used for broadcasting, they're generated by accelerating electrons inside an aerial (or antenna). An aerial is used to emit and receiveradio waves. Like all electromagnetic waves, radio waves travel at the speed of light (300 000 km/s in a vacuum).
The simplest form of radio transmission is to use a transmitter to create a radio wave of fixed frequency which you can turn on and off to create a series of pulses. Any receiver tuned to that same frequency will pick these pulses up. This was how Morse code was sent. A more sophisticated system is to use a carrier wave with a second signal imposed upon it. This is known as modulation. There are two types of modulation ó amplitude modulation (am) and frequency modulation (fm).
With amplitude modulation, the carrier wave is a wave of fixed frequency (the radio frequency that you tune your radio to) and amplitude. The sound signal you want to transmit is then superimposed upon this carrier wave. This gives you a wave of the carrier wave's frequency, but the superimposed sound wave alters the carrier wave's amplitude. The receiver can separate the carrier wave and sound wave again to give the required sound.
Frequency modulation works on the same principle except for the fact that the amplitude remains the same and the frequency of the carrier wave is altered by the superimposed sound wave.
Radio waves with wavelengths between 2km and 10m
(long, medium and short radio waves) can diffract around obstacles such
as hills and are therefore good for local radio broadcasting. They are
also reflected by the Earth and the ionosphere and so can bounce between
the two to be transmitted over long distances.
C. Microscopic Microphone to be implanted into the Vocal Cords
Near the vocal cords, a microscopic microphone unit will be installed to enable the subject to respond and communicate verbally with the other party.
Helpful Information on Vocal Cords

A) Vocal cords closed immediately prior to phonation (voice production).
B) Air Pressure develops below vocal cords due to air from lungs during exhalation.
C) Vocal cords separate briefly with the release of air. (1) Arrow points to the upper edge of the vocal cord.
D) Vocal cords re-approximate. (2) Arrow points to the lower edge of vocal cord.
E) Vocal cords together again.
The following diagram illustrates the vocal cord vibration cycle that occurs 200-400 times a second during sound production. The rapid opening and closing of the vocal cords occur in a vibratory pattern and is responsible for sound production. Thus any structural, inflammatory, or neoplastic lesion of the vocal cord affects voice production and quality.

There are lots of different types of microphone but
they all work in pretty similar ways. Any noise travels through the air
as a wave (imagine if you through a stone into a pond and watched the waves
spreading out, well sound travels like that). For a microphone to work
it must somehow pick up these waves. So it needs something which vibrates
when sound waves hit it. If you blow up a balloon and hold it next to your
mouth when you speak you'll find it vibrates and this is similar to how
this part of the microphone, called the diaphragm, works. Once you can
detect the sound waves you then need to turn them into electric currents
(so they can travel down wires, or be recorded onto tapes). Now this bit
usually involves magnets. As the diaphragm vibrates it moves a magnet (which
it is connected to) back and forth. This magnet is surrounded by coils
of wires and as the magnet moves it makes electric currents in the wires.
These electric currents can then be turned back into sound by a speaker,
which is simply a microphone, but in reverse. In a speaker the magnet stays
in the same place and there are coils of wire attached to another diaphragm.
As the currents flow round the coil they create a magnetic force which
makes the coil move (because of the big magnet around it) which in turn
moves the diaphragm, which in turn makes the air vibrate which makes the
