AN AREA-EFFICIENT UNIVERSAL CRYPTOGRAPHY PROCESSOR FOR SMART CARDS
Cryptography circuits for smart cards and portable electronic devices provide user authentication and secure data communication. These circuits should, in general, occupy small chip area, consume low power, handle several cryptography algorithms, and provide acceptable performance. This project is based on a hardware implementation of three standard cryptography algorithms on a universal architecture.The microcode cryptography processor targets smar ....etc

Introduction

The Universal Asynchronous Receiver Transmitter (UART) is the most widely used serial data communication circuit ever. UARTs allow full duplex communication over serial communication links as RS232. UARTs are available as inexpensive standard products from many semiconductor suppliers, making it unlikely that this specific design is useful by itself.

The basic functions of a UART are a microprocessor interface, double buffering of transmitter data, frame generation, parity generation, parallel to serial conversion, double buf ....etc

The term Plug-and-Play (PnP) has various meanings. In the broad sense it is just auto-configuration where one just plugs in a device and it configures itself. With the addition of Device Plug and Play (PnP) capabilities to the operating system it became a great deal easier to setup, configure, and add peripherals to a PC. Universal Plug and Play (UPnP) extends this simplicity to include the entire network, enabling discovery and control of devices, including networked devices and services, such as network-attached printers, Internet gateways, a ....etc

Universal Dossier
Objective:

Universal Dossier is a concept of public or private sharing of computer data or space in a network with various levels of access privileges. While files can easily be shared outside a network (for example, simply by handling or mailing someone your file), the term Universal Dossier almost always means sharing files in a network, even if in a small local area network. Universal Dossier allows a number of people to use the same f ....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
