Taking a look at some old patents, what they indicate, and following the development of some of the most potentially controversial inventions.
Taking a look at some old patents, what they indicate, and following the development of some of the most potentially controversial inventions.
Before you get too deep into exploring the patents listed on this website make sure that you read through the following list of pros and cons, because there are some caveats that are worth knowing.
Patents are assessed by the patent offices to be real and novel inventions with industrial applications.
WIPO FAQIf a patent is published here it indicates that it is a real invention and that it was deliberately published, not withheld for secrecy.
Full List of Our CategoriesPatents are usually designed only to claim the rights to the invention and often to deliberately obscure the intended nature of its use so people can't steal the idea.
Despite being available, people often don't accept that they are real inventions and they can react badly to being told that the technologies exist.
Categories are organised so that you can follow the development of specific inventions thorough government verifiable patents for stages in their development. Today we'll be following the development of secretive categories of inventions though patents for stages in its development. The areas featured on the homepage currently are:
Lots of them use specific sounds and frequencies to induce desired states in the brain and have applications including anti-shoplifting, creating harmonious states in multiple humans and some can cause sexual arousal.

Remote system that transmits a specific radio wave signal designed to interfere with the brain's activity in a way that yields readable results as to the brain's state that can then be analysed.
Reduce the activity of the brain with sound waves at 4-16Hz.
A patent on the synchronicity of converging tempos of recorded speech causing a specific positive emotional reaction.
Portable acoustic device that can cause sleepiness, or sexual arousal etc.
Use things like music, from a traditional speaker or an LRAD, or any other existing vibrational mechanism, to cause "Harmonious States". Potentially a real version of Cupid's bow and arrow.
A catalog of recorded emotions by brainwave state, and their related facial expressions, potentially indicating a work on a digital map of emotions (in the form of an ai model). This could later be used to figure out which of a wide array of variables can later be adjusted or controlled to induce the specific emotions. It could also be used to assess people out of reach by using cameras watching facial expression.
Using electrodes on the scalp to monitor and induce desired brain states.
As seen on TV, this is the development of the Directional Security device called the LRAD, it's used in maritime security to overwhelm aggressors, and it can cause the sensation of hearing things from nowhere but the ultrasonic vibrations do cause your ears to hear the sound unlike Radio Hearing Effect we follow later.

I think this is related to the discovery that ultrasound can cause resonating vibrations in the ears by vibrating the target with inaudible ultrasound. Sound appears to be coming from inside you.
Method of using ultrasonic waves as an undetectable communications device, using something like a building as a carrier medium.
Description of the directional uses of LRAD technology in static, mobile and man-portable for things like crowd control and as security for buildings.
Looks like a handheld LRAD style device causing people nearby to hear without feeling where the sound waves are coming from, but the ear does vibrate.
Devices using various techniques to make people feel sensations such as bugs crawling on the skin. They rely on electrical pulses, magnetic pulses, or air pulses (such as sound), applied to the person's skin using frequencies such as 1/2hz and 2.4hz to create a sensation that they are feeling something somewhere in their body.

One of the first public patents describing apparatus that allowed people to "perceive" or sense radio waves.
Application of the 1/2hz and 2.4hz frequencies being used for causing things like sleepiness or sexual arousal, but using previously mentioned electrical fields, with electrodes in contact with the skin.
Follows on from the weak electric field technique of making someone perceive a sensation on/in the body, now doing it from a short distance with magnets.
Application of the technology to make people feel sensations on or in their body using directed air pulses, instead of electrical fields.
A technology that allows electrical fields applied to the skin cause sensations. It is now able to cause twitches and tremors on demand.
Device that can cause a sensation or related effects from a remote place nearby on the top of a building for example. Using directional magnetic resonance.
Makes someone feel a sensation or the related effects mentioned earlier from pulses on a computer screen or TV (CRT).
The cause of many people's madness, directly and indirectly. This category covers development of devices that cause someone to think they have heard a voice, that's not coming from them, without vibrating the ear drums. The sound you perceive is very difficult to tell apart from things you have thought about verbalising yourself. Please note; there are other ways to make people hear a voice, such as organic suggestion and also that the symptom of hearing voices has been said to be an issue historically, before this invention category existed.

This is a significant one, one of the first to use a microwave device capable of causing someone to hear a specific sound, "representative" of the transmitted sound.
A non-specific sound is caused as a "sensation of hearing" in someone's head with microwave radio waves resonating in the auditory cortex.
"A system enabling individuals to communicate by way of monitored brain activity." By comparing the signals with previously recorded signals, you can work out what a person is thinking and potentially use some version of the radio hearing effect to reply. It is not apparent what type of thought it can cause a person to hear to enable communication, or if other types of thought than the sensation of hearing can be transmitted but seems to indicate that its possible to receive other types of thought. A mechanism for transmitting speech has not yet been patented.
A method of encoding speech using the Radio Hearing Effect, the effect where specific radio frequencies can cause the perception of hearing a sound in a auditory cortex.
A mechanism to cause specch that sounds like it comes from inside you, and now to enable communication with the technique.
A targeting system that can be used to directionally target individuals for the microwave radio waves that cause the Radio Hearing Effect.
All things to do with satellite technology.

Method of creating multiple hollograms in the air/sky from a satellite using lasers. The hollograms could be used for communications, they could take the form of any physical thing. Each satellite is supposed to cover a large area of the ground.
Technology for influencing dream states and causing dreams.

Cause certain types of dreams designed to help balance the person dreaming, the dreams are supposed to focus on the well being of the person dreaming. It uses recordings of the dreamer's voice played back at specific timings and volumes repetitively.
Allows a state of lucid dreaming (being aware of being in a dream) to be induced by using Transcranial Alternating Current Stimulation. It includes a method of testing the dream state the dreamer is in by using EEG readings.
Miscellaneous single patent inventions including a Tooth Tracking Device, and an interesting Vocal Chord Adjustment Device that can give you a different voice,

A tracking device implanted as a tooth.
A system that can make people lose their voice or sound deeper or different.
