smart sensor system for visual impairment using IoT
From the most recent data the magnitude of eye impairment and its causes in 2017 have been estimated globally and by WHO region. Surveys from 39 countries satisfied the inclusion criteria for this study. Globally,the number of people of all ages eye impaired is estimated to be 285 million,of whom 39 million are blind,with uncertainities of 10-20%.People 50 years and older represent65% and 82% of visually impaired and blind,respectively. Through this project we are trying to help the eye impaired people to lead their life without any consequences.By use of iot based sensor,we detect the obstacle or object before the blind person and intimate about them.By this sensor,they can walk out in safe manner.the current position of the vision loss humans can be found by using Global Positioning System(GPS) which is embedded in the stick.The headset and the proposed stick are paired using Bluetooth stick.Thus IOT help blind people to find their way back home by the communication between the walking stick and the headset,which are Bluetooth,paired and enable the communication between the devices.

A SURVEY ON DESIGN & IMPLEMENTATION OF MULTIBAND PLANAR MONOPOLE ANTENNA
Abstract—Industrials market are rapidly growing due to mobile & wireless communication technologies. Now a day’s voice, image & data is to provide simultaneously with high speed. These communication devices need proper antenna to fulfill the requirements for the operation of different band. Multiband planar monopole antenna have lot of advantages due to embedding a different band in single antenna. Today’s different band frequencies operate in simultaneously where modern mobile sets and smart phones are used. The mobile communication and internet need the development of microwave systems along with the release of high speed data at inexpensive prices. The aim of this paper is to study and analyze the different types of multiband antennas available and previously designed, along with different method by modification in patch , ground plane and feeding system.
