abstract on object detection using ultrasonic waves

The project is designed to demonstrate detection of any object ahead of the ultrasonic transducer. It can be used for applications like security area monitoring and wild life photography etc.This ultrasonic detector consists of two parts: an emitter, which produces a 40 kHz sound wave; and a detector, which detects this 40 kHz sound wave and sends the signal back to the microcontroller.The ultrasonic module is interfaced to the microcontroller of 8051 family. Whenever any object approaches ne ....etc

PLC-Based Monitoring Control System for Three-Phase Induction Motors
The article presents a monitoring and control system design and implementation for the three-phase induction motor based on programmable logic controller (PLC) technology. the operational parameters of the motor is correlated with the the speed requested by the user by the PLC. This is done in both the during normal operation and under trip conditions. Tests prove that a higher accuracy in speed regulation is provided by the induction motor system driven by inverter an ....etc

Piezoelectric Notions
Piezoelectricity is the ability of certain crystals to generate a voltage in response to applied mechanical stress. The word is derived from the Greek piezein, which means to squeeze or press. The piezoelectric effect is reversible in that piezoelectric crystals, when subjected to an externally applied voltage, can change shape by a small amount. The deformation, about 0.1% of the original dimension in PZT, is of the order of nanometers, but nevertheless f ....etc
