Seminar on Non invasive Brain-Machine Interfaces


Introduction

Brain-Machine Interfaces (BMI) or Brain-Computer Interfaces (BCI), also referred to as Neuro-Prostheses, are conceived as technological interfaces between a machine (usually a computer) and the brain of a user. They should permit the use to perform a certain task, usually without implementing any motor action. This implies that neural impulses generated by the user s brain are detected, elaborated and utilised by the machine, approximately in r ....etc

Abstract
Recent advances in integrated circuit technology
scaling, analog circuitry, and wireless communication
have created the possibility for complex low noise, low
power wireless instrumentation to be deployed in previously
impossible scenarios, particularly in the realm of wireless
sensing for biology research and biomedical applications. The
generation of portable, autonomous devices made possible by
these improvements will allow, for example, unobtrusive longterm
health monitoring by way of fully implantable clinical
dia ....etc

PROCESSOR-TO-ACE INTERFACES



INTRODUCTION
Among the salient features of DDC's Advanced
Communication Engine (ACE) terminals is the flexibility
of their processor and memory interface. In
today's applications, there are designs entailing the
use of multiple processors and/or multiple 1553
interfaces. Some types of systems employ both
multiple processors and multiple 1553 interfaces.
The two most common forms of the interface are
direct memory access (DMA) and shared RAM.

1. INTRODUCTION TO CRYOGENICS
Cryogenics is the study of how to get to low temperatures and of how materials behave when they get there. Besides the familiar temperature scales of Fahrenheit and Celsius (Centigrade), cryogenicists use other temperature scales, the Kelvin and Rankine temperature scale. Although the apparatus used for spacecraft is specialized, some of the general approaches are the same as used in everyday life. Cryogenics involves the study of low temperatures from about 100 Kelvin to a ....etc

Free space optical communications is a line-of-sight (LOS) technology that transmits a modulated beam of visible or infrared light through the atmosphere for broadband communications. In a manner similar to fiber optical communications, free space optics uses a light emitting diode (LED) or laser (light amplification by stimulated emission of radiation) point source for data transmission. However, in free space optics, an energy beam is collimated and transmitted through space rather than being guided through an optical cable. These beams of li ....etc
