Interesting Old Patents

Taking a look at some old US patents, what they indicate, and following the development of some of the most potentially controversial inventions.

All of these patents can be found on the USA's official patent website USPTO.gov. Most patents need to be understood and known to be a, real, and legally distinct, invention by the patent office before being published. The nature of a patent being published in this archive and in the official patent database probably indicates some legitimacy in the sense that they are real inventions and that they were published, rather than entirely withheld for secrecy.

Keep in mind that patents 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. It's not unusual to find that they appear to be saying a different thing to what they are or that they use deliberately misleading concepts or words. This effect becomes less profound with time as more people develop and get to grips with the related ideas. To someone who understands the "art", they can explain a lot. Keep your mind open.

Featured Patents

We'll be following the development of 4 secretive inventions though patents for stages in their development. The areas covered are:

These categories are organised so that you can follow the development of specific inventions thorough government verifiable patents for stages in their development. For example: You can follow the initial discovery of the Radio Hearing Effect (an effect that can cause you to think you hear a sound that you are not hearing with your ears), two way communication using sensed thoughts and replayed thoughts, to being able to transmit speech with the effect, to recorded catalogues of brainwave states of people feeling different emotions, all the way through to devices for aiming and targeting the radio waves.

There are a couple of individual bonuses at the end.

Devices That Analyse or Alter Brain States

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 in causing sexual arousal.

Directional Speakers (LRADs), and Ultrasonic Comms Devices

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.

Devices That Cause People to Feel a Specific Physical Sensation Remotely

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, 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 else in their body.

Devices That Cause and Use the Sensation of a Voice in Someone's Head

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 category indicates there is some real sanity in speaking about the fact that we can now probably communicate using recorded thoughts and that there are real applications for the knowledge.

Date Patent Number Title IOP's Short Description Further Information

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. View Patent
