ABSTRACT
Free Space Optics (FSO) or Optical Wireless, refers to the transmission of modulated visible or infrared (IR) beams through the air to obtain optical communications. Like fiber, Free Space Optics (FSO) uses lasers to transmit data, but instead of enclosing the data stream in a glass fiber, it is transmitted through the air. It is a secure, cost-effective alternative to other wireless connectivity options. This form of delivering communication has a lot of compelling advantages.
Data rates comparab ....etc

ABSTRACT


C3D or constellation 3Dâ„¢s innovative technology enables the recording,reading and storing of information on many layers within a storage media.Flourescent materials are embedded in the pits and grooves of each layer of the media and information is then stored and retrieved using the principles of fluorescence ,instead of optical reflection as currently used with CDs and DVDs .The media can be produced in card or disk format of any size. This technology holds the promise of exciting new applications and vas ....etc

1. INTRODUCTION
Technological advances are reshaping the face of manufacturing, creating paperless manufacturing environments in which computer automated process planning (CAPP) will play a preeminent role. The two reasons for this effect are: Costs are declining, which encourages partnerships between CAD and CAPP developers and access to manufacturing data is becoming easier to accomplish in multivendor environments. This is primarily due to increasing use of LANs; IGES and the like are facilitating tra ....etc

ABSTRACT
Compared with petrol, diesel is the lower quality product of petroleum family. Diesel particles are larger and heavier than petrol, thus more difficult to pulverize. Imperfect pulverization leads to more unburnt particles, hence more pollutant, lower fuel efficiency
and less power.
Common-rail technology is intended to improve the pulverization process. Conventional direct injection diesel engines must repeatedly generate fuel pressure for each injection. But in the CRDI engines the pressure ....etc

INTRODUCTION
Rapid prototyping automates the fabrication of a prototype part from a three- dimensional (3D) CAD drawing. This physical model conveys more complete information about the product earlier in the development cycle. The turnaround time for a typical rapid prototype part can take a few days. Conventional prototyping may take weeks or even months, depending on the method used. Rapid prototyping can be quicker more cost effective means of building prototypes as opposed to conventional methods.

Chapter I
INTRODUCTION
i.Background
The path of exploring the final year project had many barriers, but it made us imbibe some valuable knowledge of the field. We started searching project from internet and various magazines. We saw a number of projects from EFY and CHIP Magazine. We came across many projects on DC motor control, tachometer and RPM meters; but all these projects seemed to be very common, so using this concept we thought to have the idea of counting the RPM of any motor and we discussed this topic with our ....etc
