ABSTRACT
Electronic stethoscopes require conversion of acoustic sound
waves to electrical signals which
can then be amplified and
processed for optimal listening.
It can be a wireless recording
device, and can provide noise
reduction, signal enhancement,
and both visual and audio output .
INTRODUCTION
Electronic stethoscope is an acoustic medical device for auscultation, or listening to the internal sounds of an animal body usually.
It overcomes the low sound levels by electronic ....etc

Tool wear has long been identified as the most undesirable characteristic of the machining operations. Flank wear, is particular directly affects the work piece dimensions and the surface quality. A reliable and sensitive technique for monitoring the tool wears with out interrupting the process, is curtail in realization of the modern manufacturing concepts like unmanned machining centers, adaptive control optimization, etc. in this work an opto-electronic sensor is used in conjunction with a multilayered neural network for predicting the flan ....etc

Electronic road pricing system (ERP) the motorists are charged
In Electronic road pricing system (ERP) the motorists are charged when they use the road during peak hours.
Thus system is used to prevent traffic congestions in roads and highways.
It uses a dedicated short range radio communication system to deduct ERP charges from cash cards.

Advantages of ERPS
--------------------
1. Congestion reduction
By introducing an ERPS, users will choose alternative routes, thus reducing the number of vehicles on congested roads.
This will pro ....etc

Electronic Stethoscope-2



Assembly:

1) Assemble the circuit using Veroboard (stripboard) or a PCB.
2) Use a shielded cable for the microphone as shown on the schematic.
3) Fasten the microphone to the stethoscope head with a rubber isolating sleeve or use a short piece of rubber tubing on its nipple. A thick jar lid can be used as a stethoscope head. The microphone must be spaced away from the skin but the stethoscope head must be pressed to the skin, sealing the microphone from background noises and avoiding acoustical feedba ....etc
