Contact lenses for more stealth when infrared light, night vission or camera's will be present

 Contact lenses which will prevent reflection and glare of infrared light at the eyes.

-And not damaging for the eyes, also not when infrared light shines on the contact lenses.

More camouflaged and stealthed.

-People can easily be seen with infrared light in the dark because one or two eyes will glare up.

A parabolic dish with groves for a microphone

 A parabolic dish with groves and all. For a parabolic microphone.

Grooves, just like the ear has, but then on a round parabolic dish.

-

Extra: Parabolic dish, microphone is probably safer for humans then laser microphone. 

 Software.

Which will put all text in a video into a text file.

-

Also extra important for example, for a video of script code, screen recordings, video recordings of code language.

-Also netstat

-

Video has frames per second.

-Video is made up of a lot of single images

A small safe which is extremely hard to break open and extremely fireproof

A small safe which is extremely hard to break open and extremely fireproof.

Material(s) inside the safe should not burn or melt.

And it should be extremely hard to break open or saw open, even with powertools. And extremely hard to bypass the locking mechanism and method.

Software which will put all the text in an image into a text file

Software which will recognise all the text in an image and then puts all of that text into a text file.

A tungsten carbide padlock

A tungsten carbide, wolfram carbide padlock.

Together with multiple kinds of lock picking protections.

Researching how a new blood type came to exist and might come to exist

 Researching how a new blood type came to exist and other ways, another blood type might come to exist.

Magnetic resonance imaging and strong magnetic fields research

Doing an ethical research on what would happen if someone would be in an MRI (magnetic resonance imaging) device for weeks. 12 hours a day. While it's on.

Improvised firearm or small canon and improvised armour piercing ammunition manual

 Improvised firearm or small canon and improvised armour piercing ammunition manual.

Example (short version):

1 Barrel, strong enough

  Welding something on one side, for closing one end off

  Drilling one hole on one closed end, at the side of the barrel

2 Tungsten carbide (drillbit for example)

3 Sabot (for the ammunition)

4 Propellant powder

5 Fuse

Example 2:

An improvised firearm.

Fully making cartridges. And tungsten carbide bullets.

And something which will strike the primer pocket of the cartridge.

Important: Very dangerous.

3 litres to 5 litres molotov cocktail

 Making a molotov cocktail with a 3 litres to 5 litres glass bottle.

With a cap on the bottle. Taped tight.

And two storm matches attached to the bottle, with protective material inbetween te storm matches and the bottle.

Warning: Highly dangerous.

-Most likely also a high radius of fire.

Putting on a fire protective suit.

Throwing it backwards with two hands. As far as possible. And running away, right after throwing (just to be sure).

Or throwing it from a hight, high enough onto the ground.

-

Warning should be done on legal grounds to do so and a safe environment.

Researching the best ultrasonic frequencies for ultrasonic levitation

 Researching the best ultrasonic frequencies for ultrasonic levitation.

Silent locking pocket knives

Silent locking pocket knives.

-Switch blade knives

-Thumbstud knives

Without a click, when it locks into place.

Maybe with a material which will dampen the clicking noise to near zero decibells.

And a bigger flipper is very important then, for safety.

Two sided camouflage clothing

Two sided camouflage clothing.

For example. On one side only full white. And on the other side white and black, and maybe grey in patterns.

-Full white when there is only snow.

-And white and black in patterns for when entering long areas of snow, vegitation and trees for example, maybe.

Tests first.

Ultrasonic levitation with other kinds of waves then sine waves

Trying the following:

Ultrasonic levitation with other kinds of waves then sine waves, like square, triangle and sawtooth waves.

Getting rid of too much excess fat at the male chest

Getting rid of too much excess fat at the male chest.

Binding with cloth, probably somewhat stretchable textile. And long and somewhat broad.

Important: Research first.

More advanced silent and stealthed firearms

 Silent firearms 

Stealthed firearms

Silent cocking

Silent firing

-The hammer motion and the rest of the mechanics

 More silent ignition          (and without loss of velocity)

-And a silencer for the bullet (and without loss of velocity)

Silent ejection of cartridges

Cartridge falls silent due to casing coating

Silent semi automatic, new input of cartridges.

More silent reloading

-

And the best materials for that.

-Dampening materials. Shock absorbing materials.

A special rifle scope or scope add on for behind cover or in trenches

 A rifle scope or sniper scope. Which has multiple parts or a part which can be fitted on.

A scope or an extra part for the scope, can be done on.

--

 |

 --

Like, so it's possible to see through the scope, while the gun is on the cover, but

the person is hiding, not being visable, while it's possible to see through the scope

and shoot down enemies.

I've actually seen similar ideas from the WWI and WWII trenches. But they were more primitive.

Acoustic direction finding

And acoustic direction finding equipment.

Also for infrasound and ultrasound frequencies.
