Electronic motor speed controllers first appeared during the 1980s and many were based on dedicated integrated circuits originally designed as a servo controllers. However, with suitable circuit modifications, these ICs could also be used as the basis for a simple electronic speed controller. Since that time a number of significant events have occurred:- ? The workhorses of many older electronic motor speed controller designs, the tried and tested ZN409 and ZN419 servo amplifier ICs, have been made obsolete. ? MOSFET technology has developed an ....etc

ABSTRACT
The manual method of
synchronization demands a skilled operator and the method is suitable
for no load operation or normal frequency condition. under emergency
condition such as lowering of frequency or synchronizing of large
machines a very fast action is needed, which may not be possible for a
human operator. Thus there is a need of autosynchroniser in a power
station or in an industrial establishment where generator are employed.
This paper describes a m ....etc

SEMINAR ON MICROPROCESSOR BASED LENGTH MEASUREMENT

INTRODUCTION
An electronic scale and length measurement apparatus including electronic length measurement transducer for providing an electrical signal indicative of the length of an object to be measured.

These signals are processed by an electronic signal processing circuit including a microprocessor, a ROM and a transducer.

CONVENTIONAL LENGTH MEASURING DEVICE
The conventional length measuring devices are that they have no memory.

Rea ....etc

Electrical load on power system varies and it never be constant. To economically meet the requirement of variable load and to assure continuous supply the number of generator unit connected to the system bus bar are varied suitably.

The synchronization requires fulfillment of various conditions like
(1) Same phase sequence
(2) Equality of frequency and voltage between incoming machine and bus.

At present the synchronization is done manually by using conventional analog instruments. The ....etc

Abstract Test card for color TV is a widely used method to evaluate the quality of a TV set directly. We have made a test signal generator (which can also generate synchronizing (abbreviated to sync hereafter) signals) mainly based on microprocessor Z-80. Taking the advantage of microprocessor programming, combining with the technique of microprocessor, digital circuits and analogue devices, we use software as far as possible to generate signals directly or to simplify the controlling circuits. Those signals, such as composite sync signal, bla ....etc
