There are many ways to capture human gestures. In this paper, consideration is given to an extension to the growing trend to use sensors to capture movements and interpret these as gestures. However, rather than have sensors on people, the focus is on the attachment of sensors (i.e., strain gauges and accelerometers) to the tools that people use. By instrumenting a set of handles, which can be ...

Recently, underwater Wireless Sensor Networks (UWSNs) attracted the interest of many researchers and the past three decades have held the rapid progress of underwater acoustic communication. One of the major problems in UWSNs is how to transfer data from the mobile node to the base stations and choosing the optimized route for data transmission. Secure routing in UWSNs is necessary for packet d...

A 910MHz high efficiency RF transceiver for Wireless Body Area Network in medical application is presented in this paper. High energy efficiency transmitter and receiver architectures are proposed. In wireless body sensor network, the transmitter must have higher efficiency compared with the receiver because a large amount of data is sent from sensor node to receiver of the base station and sma...

This paper focuses on a description of the comfort by means of the temperature-humidity comfort index. In the attempt to describe this complex phenomena, those related to the human perception, for temperature and humidity estimation, we propose to use words of natural language. This linguistic description is not so accurate and also subjective than the numeric one obtained through usual sensors...

The danger of life of human being is increasing with advancement of scientific development in different fields. The security of industry (Steel Melting industry) is important to human life. The security system can detect abnormal and dangerous situation and notify us. In this paper, Virtual Instrumentation based intelligent Surveillance system that contains an obstacle avoiding robot which we c...

A piezoresistive strain-gauge sensor, mounted in an array configuration, for the measurement of distributed pressures during robotic grasp applications is investigated. The prototype presented consists of a 16-element test cell connected to an electronic acquisition unit that also provides temperature compensation. The structure of the tactile sensor and its principle of operation are described.
