A continuously variable transmission (CVT) is a transmission that can change continuously with an infinite number of effective gear ratios between maximum and minimum values. This contrasts with other mechanical transmissions that offer a set number of gear ratios. The flexibility of a CVT allows the shaft to maintain a constant angular velocity in the range of output speeds. This can provide better fuel economy than other transmissions, allowing the engine to its most efficient revolutions per minute (RPM) for a range of vehicle speeds. Altern ....etc

ABSTRACT
As the U.S. government enacts new regulations for automotive fuel economy and emissions, the continuously variable transmission, or CVT, continues to emerge as a key technology for improving the fuel efficiency of automobiles with internal combustion (IC) engines. CVTs use infinitely adjustable drive ratios instead of discrete gears to attain optimal engine performance. Since the engine always runs at the most efficient number of revolutions per minute for a given vehicle speed, CVT-equipped vehicles attain better ....etc

ABSTRACT
Continuously Variable Transmissions based on belts, pulleys, cones, discs, collectively friction transmissions, share many of the disadvantages of conventional hydraulic transmissions. CVTs require clutching mechanisms, hydraulic pumps to compress V belts between adjustable pulleys, and all have ablative belts, ....etc

CHAPTER1-INTRODUCTION
Unlike traditional automatic transmissions, continuously variable transmissions don't have a gearbox with a set number of gears. Continuous Variable Transmission (CVT), which is now replacing planetary automatic transmission in some of the automobiles. The most common type of CVT operates on an ingenious pulley system that allows an infinite variability be-tween highest and lowest gears with no discrete steps or shifts.
CVTs offer a continuum of infinitely variable gear ratios by changing the location of pull ....etc

Bluetooth Security

Abstract :

Bluetooth is a way of connecting machines to each other without cables or any other physical medium. It uses radio waves to transfer information, so it is very easily affected by attacks. In this let me first give some background information about Bluetooth system and security issues in ad hoc networks, a security framework is introduced for the description of the Bluetooth security layout.
Then both link-level and service-level security schemes are discussed in detail on the basis of the framework and then ....etc

STEPLESS SPEED DRIVES &CONTINUOUSLY VARIABLE TRANSMISSION (CVT)
INTRODUCTION
A continuously variable transmission (CVT) is a transmission that can change steplessly through an infinite number of effective gear ratios between maximum and minimum values.
This contrasts with other mechanical transmissions that offer a fixed number of gear ratios.
The flexibility of a CVT allows the driving shaft to maintain a constant angular velocity over a range of output velocities.
ADVANTAGES
This can provide better ef ....etc
