ELECTRONIC DEVICE FOR BLIND MOBILITY AID
INTRODUCTION
Many people with visual impairments can travel independently, using a wide range of tools and techniques.
Blind people are faced with many problems such as independent and graceful travel.
A long cane is used to extend the user's range of touch sensation.
It is usually swung in a low sweeping motion, across the intended path of travel, to detect obstacles.
However, techniques for cane travel can vary depending on the user ....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 gen ....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 th ....etc

Normally, hearing aid circuitsconsume battery powercontinuously once they areswitched on. The circuit given heresaves battery power by switchingon the sound amplifier section only when sound is detected. The sensitivityof the detection section and the‘on’ time duration of the sound amplifiercircuit can be set by the user.Also the circuit uses only a singlecondenser mic for sound detectionand amplification.As is clear from the above, thishearing aid consists of a condensermicrophone, earphone, and sounddetection and ampl ....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

Agriculture Aid -Seed Sprinkling and Crop Care-taking Mechanism
Abstract:
Since olden times man has been cultivating and depending heavily on the plants and crops to arrange for the staple food. To do this he had to toil and severe with labor. As the technology advances people wish for more and more comfort, reliability and fast operations. India is a farmer’s country and major part of the revenue is generated out of the agriculture industry.
Keeping the above ideology in mind we propose to design a unit with ....etc
