Abstract

A strip is provided containing information in a variety of languages. This information is not visible with the naked eye but becomes visible when a reading means is placed in front of it. The information, containing images and/or texts, is formed by micro polarised pixels. The reading means is crossed polarised so that the micro polarised pixels become visible when viewed through the reader. Different reading means may be provided to allow different portions of text to become visible so that with an appropriate reader a user will see text only in their native language.

DISCRIPTION

The Latent Multi-language Strip and The Latent Multi-language Reader

Fields of Application

This invention comprises the latent multi-language strip and the latent multi-language reader. The latent multi-language reader serves to read the information mounted on the latent multi-language step.

The latent multi-language strip contains information of Images or texts which are formed by aligning one rotation or multi-rotation micro polarised pixels to various Images or texts information. This polarised information on the latent multi-language strip is invisible to naked eyes; it becomes visible only by placing multi-language reader before it Backeround Technioue Currently, polarizing technique in manufacturing LCD, polarizing measurement, three dimensional imaging and polarised filter in photography, uses polarised material or filter to extinguish all waves except those in a single plane All light is extinguished when the two polarizing filters are said to be crossed.

In all existing signposts and outdoor information communicators, most of them support only one modality of information communication that is known as visible information support. However, the above-mentioned mediums have their limitation if more information is to be added onto a fixed communication area or an existing signpost.

For instance, foreigners or tourists with limited knowledge of the language used in the destined country may face difficulties in trying to move around. Placing various mono- language signposts or multi-language signposts may damage local environment and tarnish the local culture. It may bring confusion to drivers and pedestrians with various mono-language signposts. Furthermore, the replacement of new multi-language signposts or mono-language signposts could be very costly and time consuming As preceding modality of information communication and mediums have their limitation and shortcoming to meet the needs of users with different linguistic backgrounds, the objective of this Invention is to meet such needs. By placing the latent multi-language reader before their eyes, tourists or foreigners are able to read the latent language translations mounted onto the latent multi-language stop that is placed on the existing signposts. This invention will provide tourists and foreigners an easy access to the information on the signpost and navigate their way around the country. Furthermore, It will help to enhance country's cultural image and keep the environment in Its proper shape Content and UsaEe of me invention The shortcomings of existing signposts and outdoor information communicators can be overcome by creating a new modality of information communication through the use of the latent multi-language strip and the latent mult- language reader.

According to the preceding invention the latent multi-language strip contains information of images or texts that are formed by aligning one rotation or multi-rotation micro polarised pixels to various images or texts information. This polarised information on the latent mulh-language strip is invisible to naked eyes; it becomes visible only by placing multi-language reader before it.

The preceding latent multi-language strip contains information of images or texts that are formed by aligning one rotation or multi-rotation micro polarised pixels to various images or texts infonnation The preceding latent multi-language reader serves to read the information mounted on the latent multi-language strip. However, it reads only one language translation each time.

The preceding latent multi-language strip contains information unreadable by naked eyes.

It becomes readable by using the latent multi-language strip together with the latent multi-language reader.

The preceding latent multi-language strip contains one or multi-latent information (images or texts).

The polarised information on the preceding latent multi-language strip becomes visible only by placing multi-language reader before it irrespective of angle and distance.

The preceding invention has a significant improvement comparing with any existing products, namely signposts and outdoor information communicators. It is clear from its technical innovation that the preceding invention achieves its purposes by using the latent mulh-language strip together with the latent multi-language reader. The first component, the latent multi-language strip, is made from special polarised material and contains information (images or texts) unreadable by naked eyes. The second component: the latent multi-language reader, it serves to read the informahon mounted on the latent mulh-language strip. The information, mounted onto the preceding latent multi-language strip, becomes visible only by placing the preceding latent multi-language reader before it.

According to preceding technical innovation, this invention of the latent multi-language strip and the latent multi-language reader has the following advantages: 1.

DrawinE Description in Detail

In order to achieve its purpose, I provide the description ofthe preceding invention in detail The description is accompanied with technical drawing in terms ofthe instruction ch aracterishc and function of this invention.

The information of images or texts is added onto ordinary polarized film by aligning one rotation or mulh-rotahon micro polarised pixels to various images or texts information Each rotation of micro polarized pixel has its own corresponding 90-degree crossed rotation on the latent mulh-language reader; it appears dark when the two polarizing filters (the latent mulh-language trip and the latent multi-language reader) are said to be crossed at 90-degree. By using a particular latent multi- language reader, the corresponding rotated pixels aligned information (images or texts). The latent mulh- language ship and the latent mulh-language reader are both made from special clear film to work together as a system \ Figure 1 is the drawing ofthe latent multi-language ship in the preceding invention of latent mulbi-language quip and the latent multi-language reader The latent multi- language strip contains latent information (images and texts) and this information aligned at 45 degree rotation (45-degree rotated parallel is only for reference). In addinon, above mentioned mformabion is invisible for naked eyes and the size ofthe strip is adaptable In according to the size of signpost to which it attaches Figure 2 shows the drawing of the latent multi-language reader in the preceding invention of latent multi- language stop and latent multi-language reader. The latent multi-language reader comes in 90-degree crossed rotation corresponding to the micro polarized pixels mounted onto the latent multi-language strip m Figure I (135-degree rotated parallel is only for reference).

Figure 3 shows the drawing of the working principle. The latent language translation on the latent multi-language strip becomes visible when the corresponding latent multi- language reader in Figure 2 is placed before the latent multi-language strip in Figure 1 (irrespective of distance and angle).

For example, this invention can be applied on signposts system to overcome the shortcomings of existing signposts in not giving sufficient information for the increasing demand on information required by tourists and foreigners. Existing mono-language signposts can be upgraded to new latent multi-language signposts by attaching this latent mult-language strip on it. The corresponding language readers enable the tourists and foreigners to read the latent language translations on the signposts. For instance, latent Spanish translation becomes visible with Spanish language reader.

This invention will provide tourists and foreigners easy access to the information on the signposts and navigate their way round the country by reading the foreign languages on the latent multi-language strip attached to the signposts, so that the native language remains visible all time. This will maintain the purity of local culture and keep the environment in its proper shape.

This invention of the latent multi-language strip and the latent multilanguage reader can also be applied in other fields, such as publication, protection of copyright and so on.

All above-mentioned applications of the preceding invention do not set the limit as to the application of this invention in fields other than those mentioned above. It is within the bound of this invention should any one modifies or transforms this invention without disengaging the essentials ofthis invention. l
