The thought -translational device (TTD) consists of a training device and spelling program for the completely paralyzed using slow-cortical brain potentials (SCP). During the training phase, the self-regulation of SCPs is learned through visual-auditory feedback and positive reinforcement of SCPs; during the spelling phase, patients select letters or words with their SCPs.




A psychophysiological system for detection of cognitive functioning in completely paralyzed patients is an integral part of the TTD. The neurophysiological and a ....etc

A Linux Device Driver for USB to USB Direct Link Device

The first version of the Universal Serial Bus (USB) specification was released in January 1996. In April 2000, version 2.0 of the USB specification, which supports transfer rates up to 480 Mbps, was released. Because of its low cost, high data-transfer rate, ease of use, and flexibility, USB has gained wide acceptance in the computer industry. Today, many peripherals and devices connect to computers through USB interfaces. Currently, most general-purpose operating systems pro ....etc

charge-coupled device (CCD)

A charge-coupled device (CCD) is a light-sensitive integrated circuit that stores and displays the data for an image in such a way that each pixel (picture element) in the image is converted into an electical charge the intensity of which is related to a color in the color spectrum. For a system supporting 65,535 colors, there will be a separate value for each color that can be stored and recovered. CCDs are now commonly included in digital still and video cameras. They ....etc

For the past six years, Digital Light Processing technology from Texas Instruments has made significant inroads in the projection display market. With products enabling the world?s smallest data and video projectors, HDTV?s, and digital cinema, DLP technology is extremely powerful and flexible. With success of the DMD as a spatial light modulator for projector applications, dozens of new applications are now being enabled by general- use DMD products that are recently available to developers. The same light switching speed and ?on-off? (contras ....etc

Justin Birch lost his ability to speak in 2003 as the result of a brain aneurysm, but these days he is such a facile conversationalist he can ask for his favorite dinner”Ruby Tuesday Minis with fries and a raspberry iced tea”as well as harass his opponents after he defeats them at Texas Hold 'em.

Of course, Birch, who turns 34 this week, is a polite resident of Cape Coral, Fla., who would never intentionally annoy anyone, but it is nice to have the same speech options as those who can speak on their own. Birch (who can walk with ....etc

ABSTRACT :-
A SQUID (for superconducting quantum interference device) is a very sen
isitive magnetometer used to measure extremely weak magnetic fields, based on superconducting loops containing Josephson junctions.
SQUIDs are sensitive enough to measure fields as low as 5 aT (5×10−18 T) within a few days of averaged measurements. Their noise levels are as low as 3fT•Hz-½. For comparison, a typical refrigerator magnet produces 0.01 tesla (10−2 T), and some processes in animals produce very small magne ....etc

Biometric recognition refers to the use of distinctive physiological (e.g., fingerprints, face, retina, iris) and behavioral (e.g., gait, signature) characteristics, called biometric identifiers (or simply biometrics) for automatically recognizing individuals. Perhaps all biometric identifiers are a combination of physiological and behavioral characteristics and they should not be exclusively classified into either physiological or behavioral characteristics. For example, fingerprints may be physiological in nature but the usage of the input d ....etc

In the modern digital age which belongs to the fast and competitive ones time became one of the expensive things to spend with. Everyone tries to minimize the amount of time they spend for every deal. So technologies are emerging to satisfy this desire of people.This project aims at the point of developing an electronic system which helps people to control any process or devices from a remote location using a PSTN (Public Switched Telephone Network).So it has the name Device Controlling System.

The project is divided into two functional modu ....etc
