Rolling display using Matrix LEDs

Abstract:
This project can be used for Advertising or for providing information at various places like shops, government offices, hospitals, railway stations. The Rolling display is prepared using 5 X 7 Matrix LEDs which means LEDs are arranged in a pattern consisting of 5 columns and 7 rows. A matrix of 5 X 7 LEDs contribute to a single character. Here we have used 6 characters which means 6 matrices. The actual physical diamension of single matrix is 10 cm by 8 cm, so diamension of complete displa ....etc

Abstract—Deriving the proper density to achieve the region coverage for random sensors deployment is a fundamentally important problem in the area of wireless sensor networks. Most existing works on sensor coverage mainly concentrate on the two-dimensional (2D) plane coverage which assume that all the sensors are deployed on an ideal plane. In contrast, sensors are also deployed on the three-dimensional (3D) rolling surfaces in many real applications. Toward this end, we study the coverage problem of wireless sensor networks for the rolling t ....etc

Introduction to Rolling

Rolling is a bulk deformation process in which the thickness of the work is reduced by compressive forces exerted by two opposing rolls. The rolls rotate to pull and simultaneously squeeze the work between them.

“Flat Rolling”, used to reduce the thickness of a rectangular cross section. A closely related process is “shape rolling”, in which a square cross section is formed into a shape such as an I-beam.

It is very interesting and convenient to be able to controleverything while sitting atyour PC terminal. Here, a simplehardware circuit and software isused to interface a 7-segment basedrolling display.The printer port of a PC providesa set of points with some actingas input lines and some othersas output lines. Some lines are opencollector type which can be used asinput lines. The circuit given herecan be used for interfacing with anytype of PC’s printer port.The 25-pin parallel port connectorat the back of a PC is a combi ....etc

Introduction to CWR

The CWR is a rotary forming process, consists
of the forming of forging by means of wedge-shaped tools that are fixed on the mill rolls with the same rotary direction.
In CWR process, there are five stages in the work piece deformation process corresponding to five zones of the wedged tool geometry, i.e., knifing, guiding, stretching, shaping, and siz ....etc

WHAT EXACTLY IS ROLLING?
The majority of steel products start their life by being converted from the ingot or continuous cast form by a process of rolling. To the steel supplied in the ingot form, the preliminary treatment, given is reduced in its section by rolling. Rolling consists of passing a metal between two rolls which grip the sheet and so reduced it in size, and after each pass the rolls are brought closer together and the metal passed through until required red ....etc

DESGIN AND FABRICATION OF SPRING ROLLING MACHINE
INTRODUCTION
.A Spring is a device that changes its shape in response to an external force,
.Returning to its original shape when the force is removed.
.The energy expended in deforming the spring is stored in it and can be recovered when the spring returns to its original shape .
.The amount of deformation is directly proportional to force exerted.
