Automatic Control of Car Using Eye Blink, Air Blow And Mems Sensor and Home Security System Using Ir Sensors

2024-08-12T15:32:39+0530

This paper describes the design and implementation of a automatic remote controlled vehicle
and smart home security system using embedded system.The main purpose of this paper is to
help for physically challenged Person and aged person with several diseases such as spinal
cord injury, muscular dystrophies, multiple sclerosis etc., who have difficulty in conveying
their intension and communicating with other people in day to day life. In this paper a
prototype is developed to help them by designing a automatic car controlled system with
combination of several low cost sensors for vehicle controlling and home security system. In
this paper we discuss the design and implementation of an intelligent remote controlled
vehicle working on standard wireless sensor network i.e. ZIGBEE as a transceiver and not by
the usual method of keypad for the physically handicapped people.In this work we are
designing automatic remote control vehicle that can be controlled by combination of three
sensors namely EYE BLINK,AIR BLOW by mouth, MEMS sensor and ZIGBEE as a standardbased home-area wireless network .AIR BLOW sensor is connected to person mouth to start
the vehicle. MEMS sensors are based on hand movement of person fingers and it is used to
change the direction vehicle towards right or left. EYE BLINK sensor used here to stop the
vehicle that is connected person’s eye. This implementation also has home security system for
deaf and dumb. In the second section of this work an elderly person monitoring has been
done. Since it is difficult to monitor elderly disable person for 24 hours, when we are out of
home for any reason. If anyone enters to our home and during that time second section of
this work is to be used to monitor from where person is entering to home, if person is
entering from the door, receiver will receive the signal and message will be displayed that
from where person is entering to home and green light will be activated with vibrator, else if he is entering from window red light will be activated with vibrator and corresponding
message will be displayed on LCD display. The method of transmitting and receiving data
was done wirelessly using a ZigBee device.

Digital Watermarking Technique For Protecting Data and Image Authentication

2024-08-12T15:22:02+0530

Due to immense growth in the online data storage, security of the important information has
become a keen point of interest. Hiding of an information involves its concealment, so that an
eavesdropper does not trace out the existence of that information. In the field of image
processing, the data hiding techniques play a vital role for authenticating the digital data and
its copyright protection. Digital watermarking is one of the efficient technique for embedding
significant information over the digital signals in order to check and maintain the
authenticity of it’s author and to safeguard it from being used illegally.In this paper, a
creamer framework utilizing three individual watermarking systems i.e. Discrete Wavelet
Transform (DWT), Discrete Cosine Transform (DCT) and Singular Value Decomposition
(SVD) is proposed. This strategy abuses the upsides of the three individual frameworks and
in this way gives a prevalent security arrangement when appeared differently in relation to
various techniques. The examination of scale segment used as a part of the proposed
procedure close by the graphical results is moreover done.

REACTIVE POWER COMPENSATION WITH THE HELP OF VOLTAGE CONTROLLED D-STATCOM

2024-08-12T15:27:13+0530

In this paper new method for voltage controlled mode of D-STATCOM will used for
reference voltage generation while in traditional method of VCM (voltage controlled mode)
reference voltage will taken as 1 p.u. In this new method it is possible to achieve unity power
factor at load terminal which is not possible in traditional method. Also, loss in the new
method will less as compare to traditional method. This is due to more current supplied by
compensator in traditional method as compared to new method. In both the method DSTATCOM each phase will contain three capacitor for removing high switching frequency.
Also, it is possible to clear sag for more time as compare to traditional method. Through
detailed simulation and experimental results, it will found that load will not affected due to
sag & also possible to achieve UPF in new method.
