FIELD OF INVENTION
This invention relates to advertising industry. Further, this invention relates to Bill Boards, More particularly this invention relates to Hybrid Bill Boards.
INTRODUCTION
It is known that at present each and every industry intends to demonstrate their product to the public by using media. In media, several types are there. Some of the media are T.V., Radio, Newspaper, and Bill Boards.
Among various options available, billboards contributes major role in the advertising industry. Now billboards are available in different sizes and in different styles using different technology.
It is known facts that there are several varieties of billboards are available in the market. Some of them are 1. Static Paint Billboard, 2. Screen Bill Boards, 3. Rotating Billboard. Each one has it is own drawbacks. Some of them are referred in the following
description.
In paint billboards, the major drawback is the reality of the image depends upon the skill of the painter and ii is possible to show the only one still by using this type of
media.
In screen billboard, we can obtain the realistic style of the product but it can show only one image. To overcome this problem leads to the emergence of rotating billboard
has been anticipated.
In billboard one can show maximum of 4 verities that too cost loosing realistic style of the product, because we have to split the whole screen into number of segments and this segments are pasted in the faces of rolling of square or in rolling triangle. Each roller takes appropriate position to show that particular image & in this technique each and ever}' roller has its own gap to rotate so that one did not get realistic image of the product. To overcome ail those 4ifficulties we have invented hybrid billboard has been invented.

Further, the following description described the state of art method, technology, and device in the advertising industry.
STATE OF ART TECHNOLOGY
Following description, discuss about the existing technologies and its drawbacks in field of billboards among in the media.
The available or existing technologies in field of hoardings are
1. Painted Bill Board
2. Digital led display
3. Screen Bill Board
= 4. Rotating segment bill board 5. Projector screen bill board
1 PAINT BILL BOARD
In Recent, year's people are using painted billboards for advertisement.
Painted billboard advertisement image is fully depends upon the skill of the painters. It is time consuming process & cost high, so that it is not successftil. Risjc factor is high when compared other technique. (While painting, the painter has to hang on the advertisement board. In modern technology to catch the advertisement market, it is not enough to advertise through painted billboard, because realistic image of the product cannot be obtained.
2. DIGITAL DISPLY
To over come above discussed proplem and to show the many stills on the same Board digital led display was invented.
In this technique each led contribute in the image of the product by glowing on or off. But major drawback in this type'is realistic image of the product cannot be achieved. Moreover, it can be used oniy in the nighttime. At first, it was available only in two colours, i.e.: monochrome.

Now digital led display is available many colours. Even it is available in many colours it is resolution of the image is very poor. Because the led are not so dense to get the reality. Its advantage is the advertising time & number of slides per minute is programmable. Even though it is not widely used because of its draw back.
3. SCREEN BILL BOARD
To get the realistic image of the product screen billboards are used. It eliminates possible drawbacks due to the realistic image difficulties discussed in the previous billboard techniques.
In this technique, the photography of the product is enlarged on the screen and it is pasted on the rough skin to get the rigidity. This helps to the industry to show their product to public and it is visible during day & nights.
Its only drawback is, one can show only one image at a time, so the cost of the still is too high when compared to painted billboards & digital led display.
4. ROTATING SEGMENT BILL BOARD
In this technique, more than one image can be obtained up to maximum of 4
»■
images. In which square roller or triangular rollers are used. In each face of it is the segments of the same image are pasted on the rollers.
Each one take it is own position to show one particular image. Each roller get drive from stepper motor. The timer circuit controls the time of the one particular image showed by roller. Therefore, it is programmable.
There is a gap between each roller so that realistic image cannot be obtained in this type of advertisement. The image on the roller segment billboard can be viewed during day and night The only problem with this technique is the limitation for number of and realistic image cannot be obtained.

5. PROJECTOR SCREEN BILL BOARI
In this type, the images are obtained from the projector, which is stored in the computer. It has realistic image and unlimited number of images can be showed. Projector screen and computer is enough to show ad and it has realistic effect.
The problem with this technique is that of it has dull effect in lighting or in bright places because it has interference between the projector light and surrounding light. So? it must be used only in night times..

Figure 1: - illustrates the principle of the Hybrid billboard. In this figure we can see two rollers one top & bottom roller, and both will rotate to show the different advertisement Images, which is kept in the rolled form.
The invention of hybrid rolling screen billboard came to overcome the earlier stated difficulties faced in the other types. Now we are going to discuss the invention i.e. the principle of hybrid billboard.
In this bill board the realistic screen will be keep on changing at interval of time for (i.e.: set time). Full the day refer figure - 1.
Figure 2: - This figure illustrates order in which images are shown while continuous running.

Unwinding screen roller. We keep the 30 and above of images in the rolled form. The direction of the rotation of roller changes after the complete winding of the screen on the bottom roller, at this time the initially bottom roller acts as a winding roller & top roller image screen displayed at the last will be the first and it will keep on showing images in the reverse order refer figure - 2.
Figure 3: - This illustrates the cross section of the screen. This consists of three layers
skin, Sticking paste coating vinyl (or) Paper images.
Figure 4: - this shows the view of the screen before & after side pulling
The first one shows the screen before side pulling with lot of wrinkles and Second one
shows perfect wrinkle free view of the screen after side pulling.
Figure 4A; - This shows the drive arrangements .In this arrangement only one motor is
used to rotate both bottom and top roller but at a time it operates only one roller using
two Electromagnetic clutch arrangement provided with timing belt and programmable
logical controller operates it
Figure 5: this shows the cross section of the fiction clutch type roller tensioned. In this unit spring operated pad exerts side friction. This performs the controlled sheet unwinding from the roller and it also performing vertical sheet tensioning.
Figure 6: this figure shows the electromagnetic side pulling arrangements for eliminating vertical wrinkles. In this figure, side-tensioning load given by the spring finally goes to the sheet through nylon mandrel, which is operated by electromagnet. The and for -movement of the nylon mandrel and total inward movement is required for sheet movement i.e. to show different images. The inward of the total unit is done by rope and motor arrangement.
Figure7; this shows the electromagnet unit used in side pulling unit. This unit gives to & for movement to the nylon mandrel. Nylon Mandrel pulling is done by electromagnetic force, and forward movement (i.e. return) by spring.
FigureS: this figure shows the rope and motor assy. This unit pulls and releases side pulling unit while moving the sheet. The purpose of side pulling unit inward movement is for easy nylon mandrel reentering into the sheet, and releasing i.e. outward movement is for side tightening of the sheet after sheet movement In this unit worm geared motor rotates the rope-winding shaft. The motor on off is controlled by plc and time delay unit

(mechanical) to increase the running time (i.e. time between the switching on & switching off).
Figure 9: this shows the time delay unit; this unit consists of three rollers & two guide rods and spring. The moving roller moves up and down by the spring and winding shaft rotation. The main purpose of the unit is to increase the running time of the unwinding motor.(i.e. time between the motor start & stop)
Figure 10: show the total general assembly of the hybrid billboard
The screen contains two materials
1. Flex (Artificial fiber based cloth)
2. Vinyl (or) paper (Image printed screen). The flex baclcing is the permanent rotating member. The vinyl (or) paper sties with flex backing by the sticking paste coating refer figure - 3.
The figure 4 shows about side pulling the screen if we see the screen before side pulling one can see lot of vertical wrinkles on the.screen this spoils the clarity of the image. So avoid this problem we decided to use automated side pulling system the figure in the side pulling system shows clear image of advertisement after side pulling.
The automated side pulling mainly comprises two units.
1. Electro magnet assembly
2. Rope pulling assembly
1. ELECTRO MAGNET ASSEMBLY
In this assembly nylon mandrel moves to and fro for side pulling the screen. The nylon moves forward using spring provided in assembly and it be retracted using electromagnet.
2. ROPE PULLING ASSEMBLY

This assembly pulls the whole electro magnet assembly while screen changing. OPERATION OF SIDE PULLING
Initially the electro magnet assembly pulls the flex sheet by the spring provided by this way we are eliminating vertical wrinkles using oppositely positioned electro magnets. While moving the screen nylon mandrel tomes out from the slotted screen and total unit moves inward for easy reentering into the slotted screen (because the slotted portion of this screen moves slightly inward due to the vertical wrinkles).
And to give effective side pulling, rope pulling assembly is totally actuated by
the geared motor and sensor circuit _.
