Definition
Micro-electromechanical systems (MEMS) is a technology that combines computers with tiny mechanical devices such as sensors, valves, gears, mirrors, and actuators embedded in semiconductor chips.




Overview
MEMS are already used as accelerometers in automobile air-bags. They've replaced a less reliable device at lower cost and show promise of being able to inflate a bag not only on the basis of sensed deceleration but also on the basis of the size of the person they are protecting. Basically, a MEMS device contains micro-cir ....etc

Real-time systems play a considerable role in our society, and they cover a spectrum from the very simple to the very complex. Examples of current real-time systems include the control of domestic appliances like washing machines and televisions, the control of automobile engines, telecommunication switching systems, military command and control systems, industrial process control, flight control systems, and space shuttle and aircraft avionics.

All of these involve gathering data from the environment, processing of gathered data ....etc

Now a day it is very important to increase the efficiency of IC engines due to many factors such as fuel economy, fuel crisis and ultimately to increase the output. Here comes the importance of effective cooling systems in IC engine.

The advanced cooling concepts are proposed to overcome the shortcomings arising when applying conventional cooling methods. The various effects of overheating the engine components due to the improper cooling and conventional cooling methods have also being discussed.


During the process of combustion a lar ....etc

Here’s a stepper motor controllerbased on 89C51 microcontroller tocontrol the rotation of a DC steppermotor in clockwise and anti-clockwisedirections. The controller is simple andeasy-to-construct, and can be used in manyapplications including machine control androbotics for controlling the axial rotation inXY plane. A similar circuit can be added tocontrol the rotation of the motor in eitherXZ or YZ plane.Fig. 1 shows the block diagram of thestepper motor control system. The powersupply section (in Fig. 2) consists of a stepdowntransformer ....etc
