In summary, the conversation is about a patent for an electroencephalographic apparatus that measures a person's brainwave signals in response to external stimuli. The device includes sensing, stimulating, and processing apparatus to compute a correlation quotient between the brainwave signals and stimuli. It can show which brain regions are most active in response to different stimuli and measure biochemical reactions in the brain. The individual is seeking a clearer understanding of the device's specific functions.

Hi,

i have studying the following paten for a few months and i would ike to know if anybody understands this patent and what its about.

http://patft.uspto.gov/netacgi/nph-...50&s1=5788648.PN.&OS=PN/5788648&RS=PN/5788648

the above link contains images and description of the patent. if anybody understands it can u pls explain it 2 me.

thank u.

- Sid

from the abstract it looks like the device stimulates the brain then measures the resulting brain waves. do you have more specific questions?

Well : "An electroencephalographic apparatus for exploring a person's response to external stimuli, which includes electroencephalographic sensing apparatus for sensing brainwave signals from the person; stimulating apparatus for generating the stimuli; and processing apparatus having at least a first input operative for receiving the brainwave signals, at least a second input for monitoring the stimuli; the processing apparatus including computing apparatus operative for computing a correlation quotient of the brainwave signals and the stimuli"

It measures how our brain reacts to external stimuli (eg : how does our brain react biochemically if we see certain pictures of loved ones interchaged with pictures of dictators). The apparatus is able to show us which brain regions are most active in such cases. What is actually show is the biochemical reactions in the brain (nerve cell activity etc etc) that occur as a reaction to the external stimuli.

1. What is an electroencephalographic apparatus patent?

An electroencephalographic apparatus patent is a type of patent that protects the design and function of a device used to measure and record electrical activity in the brain, known as an electroencephalogram (EEG). This type of patent is typically granted to the inventor or company that created the apparatus, giving them exclusive rights to manufacture and sell the device for a certain period of time.

2. What is the purpose of an electroencephalographic apparatus?

The purpose of an electroencephalographic apparatus is to detect and record electrical signals produced by the brain. This can be used for various medical purposes, such as diagnosing neurological disorders, monitoring brain activity during surgery, or studying brain function and behavior. It can also be used in non-medical applications, such as in research or in the development of brain-computer interface technology.

3. How does an electroencephalographic apparatus work?

An electroencephalographic apparatus works by using sensors, called electrodes, to detect and amplify the tiny electrical signals produced by the brain. These signals are then recorded and displayed as a visual representation, known as an EEG, which can be interpreted by a trained professional. The apparatus may also have additional features, such as the ability to stimulate the brain or filter out unwanted signals.

4. Who can apply for an electroencephalographic apparatus patent?

Anyone who has invented a new and useful electroencephalographic apparatus may apply for a patent. This can include individuals, companies, or research institutions. However, the invention must meet certain criteria, such as being novel, non-obvious, and useful, in order to be granted a patent by the appropriate government agency.

5. How long does an electroencephalographic apparatus patent last?

The length of an electroencephalographic apparatus patent varies depending on the country in which it is granted. In the United States, a patent for an apparatus typically lasts for 20 years from the date of filing the application. However, the patent owner may be able to renew the patent for additional periods of time, if certain requirements are met. Other countries may have different patent terms and renewal processes.
