wireless sensor networks (wsns) are one of the most interesting consequences of innovations in different areas of technology including wireless and mobile communications, networking, and sensor design. these networks are considered as a class of wireless networks which are constructed by a set of sensors. a large number of applications have been proposed for wsns. besides having numerous applic...
Tothe latest survey organized by the Times of India (ToI), currently, is domestic to globe’s biggest variety sightless human beings. Among forty million beings throughout world were blind, from this above 15 blinds are India. Technology aspires make our lives better. Just like smartphones, smart TVs, and automobiles, advocated us recommend an intelligent stick that uses ultrasonic sensors for v...
In spite of many advantages ultrasonic gas flow meters are not generally accepted in the market of flow measuring instruments. Most of them are operating with ultrasonic impulses using the principle of time-of-flight measurement. Vortex frequency measurements up to now don’t use ultrasound for the detection of frequency although the sensitivity can be increased up to ten times and analogue sign...
This paper describes short range and tactile optical fibre sensors for marine applications. The sensors are designed for obstacle avoidance on unmanned underwater vehicles (UUVs) operating in confined spaces, but have other possible applications. The fibre sensors augment the sensory abilities derived from ultrasonic and other sensors employed for marine proximity measurement. Of particular int...
In the mobile robot navigation, the ultrasonic sensors have been widely used for the obstacles detection and map building because of its cost and efficiency. Generally sensors are used to increase the accuracy of the obstacles position and decrease the time. In this paper an ultrasonic sensor is interfaced on to a stepper motor which will be constantly revolving and detecting the values of any ...
In this paper an oil-water de-emulsification process within large tanks using ultrasonic technology is presented. As the device would operate in hazardous areas, it should not consume an excessive amount of electrical power. Hence, the paper investigates the suitable oil-water concentrations (10-90% concentrations in step of 10%) which would lead to the fastest separation while consuming the mi...
Ultrasonic flow meters are gaining wide usage in commercial, industrial and medical applications. Major benefits of utilizing this type of flowmeter are higher accuracy, low maintenance (no moving parts), noninvasive flow measurement, and the ability to regularly diagnose health of the meter. This application note is intended as an introduction to ultrasonic time-of-flight (TOF) flow sensing us...
As per the rapidly advancement in the changing technology, the numerous applications are required. For example, for face, hand and gesture recognition. The previous researchers have been developed various methods foe head gesture recognition and they presented various limitations. Therefore the paper proposes an FPGA based gesture recognition system. The gesture detection and gesture recognitio...
In this paper we present the design of a car test bed. The main characteristic of our test bed is the steering which is Non-Holonomic to resemble the normal car steering. This test bed is a rear wheel drive with frontal steering by servo motor. The control brain consists of RoBoard II and Arduino Micro controller. We used multiple sensors (Ultrasonic range finder, 6 DOF Accelerometer, Wheel enc...
