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

MICROCONTROLLER BASED WALKING AID FOR BLIND & DEAF

Abstract
Biomedical engineering specializes in making life easier for the physically challenged. Our project is an endeavor in this direction. IR sensor mounted on to the stick is used for detecting obstacles in the path of the user and a vibrational feedback is provided which is decided by microcontroller. The same circuit is mounted on a cap for detecting overhanging obstacles. ....etc

ABSTRACT

LPG gas is supplied in pressurized steel cylinders. As this gas is heavier than air, when it leaks from a cylinder it flows along floor and tends to settle in low spots such as a basement. This can cause fire or suffocation if not dealt with. Here is a circuit that detects the leakage of LPG gas and alerts the user through audio-visual indications.

This LPG Gas Sensor (MQ6), ideal sensor for use to detect the presence of a dangerous Liquefied petroleum gas (LPG) and it has high sensitivity to propane, butane, isobutene, natural ....etc

seminar report for a voice input voice output communication aid for people with severe speech impairment

Abstract
Abstract A new form of augmentative and alternative communication (AAC) device for people with severe speech impairment the voice-input voice-output communication aid (VIVOCA) is described. The VIVOCA recognizes the disordered speech of the user and builds messages, which are converted into synthetic speech. System development was carried out employing user-centered design and development methods, which identified and refined ke ....etc

Abstract
Blind people need to become as independent as
possible in their daily life in order to guarantee a fully social
inclusion. Mobility means the possibility of freely moving,
without support of any accompanying person, at home, in public
and private buildings, and in open spaces, as the streets of the
town. Mobile and wireless technologies, and in particular the
ones used to locate persons or objects, can be used to realize
navigation systems in an intelligent environment. Such systems
open new opportunities to improve the ....etc

Ultrasound Usage in Mobility Aid Systems



The mobility aid system works on the simple principle of reflection of sound waves from the obstacle or an object. For this set up, the system has a simple battery operated circuit, acting as an oscillator producing the required 40 KHz frequency for the operation of the ultrasound generator. The ultrasound generator generates sound waves, which are higher in frequency than the human audible range . Thus generated, sound waves bu ....etc
