MicroElectroMechanical Systems, MEMS, are systems based on a range of techologies whereby tiny mechanical elements, both sensors and actuators, can be implemented.It turns out that these elements have excellent system properties.The elements are often interfaced to microelectronical driving or sensing components (ICs) by appropriate packaging or on the same silicon wafer. The semiconductor silicon is not only good for making electronics but its material properties are extremely good.Thus, Micro electromechanical systems (MEMS) refer to a collec ....etc

Connectivity Restoration in Wireless Sensor and Actor Networks

Abstract”

Recent years have witnessed a growing interest in applications of wireless sensor and actor networks (WSANs). In these applications, a set of mobile actor nodes are deployed in addition to sensors in order to collect sensorsâ„¢ data and perform specific tasks in response to detected events/objects. In most scenarios, actors have to respond collectively, which requires interactor coordination. Therefore, maintaining a connected interactor network is c ....etc

This project is mainly focused on designing an intelligent refrigerator which finds out the stock of the material present in it and then automatically places order for the nearest online shop via internet using IEEE 802.3U technology, if the stock is below threshold. This system uses few sensors that monitors the stock level of the items in the fridge. It employs sensors below each item in the fridge and if any item is removed the Processor comes to know about that and checks that with the threshold level and if it is below the threshold leve ....etc

A Low-Cost Efficient Wireless Architecture for Rural Network Connectivity


Introduction
Many rural regions around the world, especially in developing regions, do not have good connectivity
solutions which are economically viable. As a result, many of these regions remain disconnected
from both the rest of the world and from progress in general. In this proposal, I will describe
the design of WiFi-based Rural Extensions (WiRE), a new wireless network archite ....etc

MEMS technology has enabled us to realize advanced micro devices by using processes similar to VLSI technology. When MEMS devices are combined with other technologies new generation of innovative technology will b created. This will offer outstanding functionality. Such technologies will have wide scale applications in fields ranging from automotive, aerodynamics, hydrodynamics, bio-medical and so forth. The main challenge is to integrate all these potentially non-compatible technologies into a single working microsystem that will offer outsta ....etc
