DESIGN AND IMPLEMENTATION OF SEISMIC SENSOR


INTRODUCTION
1.1 Overview
There are two basic types of seismic sensors: inertial seismometers which measure ground motion relative to an inertial reference (a suspended mass), and strainmeters or extensometers which measure the motion of one point of the ground relative to another. Since the motion of the ground relative to an inertial reference is in most cases much larger than the differential motion withi ....etc

Abstract
This report is based on the two reference papers that were published earlier. Thefirst reference paper is “ Customer Self-Service in the hybrid library” published byInternational Network of Public Libraries Bertelsmann Foundation, Gütersloh, Germanyin 2002.In the first reference paper the authors basically explored the art of the selfservicein the international libraries. How ever I only refer to the part of this paper,especially advantages ....etc

This article describes methods of speech processing especially for cellular systems and internet voice communication.Oneof the most popular formats used for speech processing is PCM (Pulse Code Modulation) format, which has a high processing accuracy.However,long words and timeconsuming multiply operationsrestricts the usage of PCM codes.More advantageous to that,DPCM (Differential Pulse Code Modulation), which has a similar resolution as PCM but operates on shorter word lengths was developed DPCM uses delta modulation (DM) codes to obtain bet ....etc

SEISMIC SENSOR


D. MOHAN KUMAR



This circuit simulates a seismic sensor to detect vibrations/ sounds. It is very sensitive and can detect vibrations caused by the movement of animals or human beings. So it can be used to monitor protected areas to restrict entry of unwanted persons or animals. The circuit uses readily available components and the design is straightforward. A standard piezo sensor is used to detect vibrations/sounds due to pressure changes. The piezo element act ....etc

Power line communication (PLC) presents an interesting and economical solution for Automatic Meter Reading (AMR). A mechanism to detect the illegal electricity usage can be added in the existing PLC network. In this system , second digitally energy meter chip is used and the value of utilised energy is stored and than this is compared with the main kilo Watt-hour meter. error signal is generated and transmitted via PLC network is there is any anomaly in the reading of the meter and the value stored in the chip.

Detection of illegal elec ....etc
