Abstract

Proximity Detection is a technique for realizing any obstruction in a given range. The technique involves an injection of an additional pulse to a piezotransmitter for amplification and calibration of reflecting pulse from the obstruction, which is received by piezoreceiver. The technique “Ultra Sonic Proximity Detector (USPD)” is found useful in particularly to design the Blind Stick1, 2, which can makes the life of a blind person more comfortable during walking. Not much has been done in the field to improve the sensitivity of the blind stick. In this article the proximity detector is design in such a way which is high sensitive and having both option for wireless head phone and buzzer.
