PPT on Holographic Memory

Holographic memory is a technology that can store information at high density inside   crystals or photopolymers.

 Conventional memories use only the surface to store the data.  But holographic data storage systems use the volume to store data.  It has more advantages than conventional storage systems.  It is based on the principle of holography.

Unlike magnetic storage mechanisms which store data on their surfaces, holographic memories store information throughout their whole volume. After a page of data is recorded

PPT on Thyristor

The thyristor is a four-layer, three terminal semiconducting device, with each layer consisting of alternately N-type  or P-type material, for example P-N-P-N. Four-layer devices act as either open or closed switches; for this reason, they are most frequently used in control applications. They stay on once they are triggered, and will go off only if current is too low or when triggered off. The SCR is the most widely used and important member of the thyristor family. The SCR is almost universally referred to as thyristor. Common areas of application for SCRs are  Time-delay circuits, regulated power suppliers, static switches, motor controls choppers, battery charger and heater controls. Etch..

PPT on Nano Sensor

Nanosensors are any biological, chemical, or surgical sensory points used to convey information about nanoparticles to the macroscopic world. Their use mainly include various medicinal purposes and as gateways to building other nanoproducts, such as computer chips that work at the nanoscale and nanorobots

PPT on Laser Bar-code scanner

A barcode reader (or barcode scanner) is an electronic device for reading printed barcodes. Like a flatbed scanner, it consists of a light source, a lens and a light sensor translating optical impulses into electrical ones. Additionally, nearly all barcode readers contain decoder circuitry analyzing the barcode's image data provided by the sensor and sending the barcode's content to the scanner's output port.

PPT on Digital Signature

A digital signature or digital signature scheme is a mathematical scheme for demonstrating the authenticity of a digital message or document. A valid digital signature gives a recipient reason to believe that the message was created by a known sender, and that it was not altered in transit. Digital signatures are commonly used for software distribution, financial transactions, and in other cases where it is important to detect forgery or tampering.
