Display devices form an important group of devices in the electro industry. With the evolution of high definition TV (HDTV), video conferencing and other advancements in video applications, their importance is increasing. Traditionally cathode ray tubes (CRTs) are used in display devices. But the industry is searching for devices with high resolution and fill ratios that cannot be achieved in CRTs. LCDs can be use an alternative but they are not cost effective. An entirely new type of devices based on Grating Light Valve technology solves all t ....etc

The VRB-ESS is a device that is capable of storing energy in multi megawatt ranges for durations that range from hours to days, from any available input source such as Grid, Renewable resources or even from a diesel generator. The stored energy can then be provided back into the Grid or supplied to a load as required & directed. It is uniquely capable of being charged as quickly as it was discharged. This seminar presents the various features & applications of the VRB and discusses its future in the coming years.

INTRODUCTION
If you're thinking about assembling a home theatre system, you may be looking at large screen televisions as the heart of your system. Projection TV could give you the size that you want -- CRT screens generally top out at 40 (101 cm) or so, and at that size, they are huge and heavy. Plasma screens can be bigger than that and still manageable, but they can be extremely expensive. Projection TV technology can create large screen sizes at a reasonable price. Or maybe you need to equip a room, like ....etc

BATTERY CHARGERS & BATTERY BANKS
INTRODUCTION
NEED OF BATTERY CHARGERS & BATTERY BANKS
Station battery charger is used to supply the control power to the electrical switchgear like breakers etc which need the DC supply for it’s operation and in case of failure of electrical power the control power is continued to be fed by the battery.
Battery Charger consists of
1) Float Charger
2) Boost Charger
Schemes for Battery Chargers
1) FC & FCBC scheme
2) FCBC & FCBC scheme
SINGLE LINE ....etc
