    Portable device for the reproduction of digital documents in braille, which is capable of reproducing autonomously and in braille alphabet any type of digital document that is loaded into its memory by means of a computer. Reproduction will use electromagnetic elements that allow the representation of the braille characters, thus allowing the reading by touch. The device will display in a visual way through a screen, the characters that are being played, in addition to the battery status, volume and setting of the type of playback. It also has a built-in 2x3 led matrix that simulates, through its ignition, braille alphabet reproduction while the touch system does. It has a built-in loudspeaker that reproduces the characters that are reproduced in audio form. To control the device, it incorporates a panel of buttons with which you can change the playback mode or pause it. (Machine-translation by Google Translate, not legally binding)

     5 Portable Device for the Reproduction of Digital Documents in Braille TECHNICAL SECTOR The invention is included within the computer engineering sector. The invention is included within the sector of application of education, teaching and leisure. 10 BACKGROUND OF THE INVENTION The present invention aims to develop a hardware device for the representation of Bra iIIe characters, in order to reproduce any text stored in the memory of the device in Braille format. There are currently 15 devices called braille lines, which connected to a computer, are capable of reproducing the characters that appear on the screen, their use being similar to a monitor that instead of reproducing the computer's output in visual mode they do it in Braille format , which means they must be connected to a computer for use. 20 The functionality of this device allows us to connect it to a computer and to be able to enter in its memory different text documents, such as books, magazines or any text that we have stored in the computer. This process is performed using software designed specifically for this device. Once the device contains documents we can disconnect it from the computer and thanks to 25 its internal battery can be turned on and reproduce the text documents it contains in its memory. What allows to have a portable reading device in Braille format, with which, we can make use of it as if it were an electronic book, with the difference that instead of reproducing in visual format it reproduces the characters in Braille format. 30 The Spanish patent "ES2202570T3" describes a portable reading device that uses optical sensors in order to process a printed text, reproducing it by means of a microcapsule attached to a sleeve into which the fingertip index finger is introduced as a thimble . This microcapsule is composed of a matrix of optical sensors and an electromagnetic unit to reproduce character 2braille, as long as the blind person's index finger scrolls through the already printed braille character, for example in. A braille book in paper format. The device that is intended to be developed is totally different, since the Spanish patent 5 mentioned above, focuses on the recognition of braille characters through an optical sensor incorporated in a thimble, which, the user must go through a physical means to perform the reading. Therefore, the reader of the present invention does not use this technology since it does not have optical sensors or thimbles, but, as will be described later, the entry of the information will be done by connecting to a computer, thus not being necessary the use of any physical means for the device to obtain braille information. The patent "W02013039369A1" mentions a portable electronic braille reader, which makes use of a thimble that is placed on the index finger of the blind person 15 for braille reading and a capacitive screen about the size of a folio A4 approximately which is where all the braille characters will be reflected non-visually, in order to move the thimble through the capacitive screen to be able to perform the braille reading as if it were a paper book. Therefore, the reader of the present invention is totally different, since it does not need a capacitive screen to simulate a sheet of paper, nor a thimble for the representation of the braille characters, nor is the sliding of the blind person's finger necessary for the Braille reading, as will be detailed in the explanation of the present invention. 25 The patent "GB2231702" is similar to the previous one mentioned since it also makes use of a thimble for the reproduction of braille characters, but in this case it is not necessary to pass the thimble through a capacitive screen for reading, but it consists of a scanner that by putting a paper printed document on a scanner that has the device incorporated, is able to digitize and transform that form and reproduce it in Braille using the thimble that the blind person has placed on his index finger. Therefore, the reader of the present invention differs both in the way of obtaining the information and in reproducing it, as will be detailed in the explanation of the present invention. 35 Other patents referring to Braille are "JPH08241 033", "US3340625A", 3"ES2250555T3". These patents refer to devices that connect to a computer and are capable of reproducing the text that appears on the computer screen in Braille format. These devices are not portable because they have to be connected to the computer for their operation and their function is not to reproduce documents, but to provide the information of the computer screen to the blind. EXPLANATION OF THE INVENTION 10 Portable device for the reproduction of digital documents in Braille. The present invention consists in the development of a device that is capable of reproducing autonomously and in Braille alphabet any type of digital document that is loaded into its memory by means of a computer. The components used are: -Microcontroller Arduino Mega. -Shield Audio and Wifi for Arduino. - Linear solenoids. 20 -Speaker. 25-16x2 LeO matrix. -Lipo battery. -Leds matrix 2x3. -Buttons switches. The microcontroller will have connected all the components detailed above, which will activate all the elements for the reproduction of braille characters. 30 The audio shield will reproduce the characters by means of a loudspeaker in the form of sound, in such a way, while the characters are reproduced in Braille will be reproduced by the loudspeaker. This feature is optional and configurable using the device buttons. 35 The shield wifi will provide connectivity to the device with a computer. Through 4This wireless connection can manage the device memory, allowing the insertion of new documents, among other features. In addition to Wi-Fi connection, the Arduino shield allows USB connection with a 2x3 Led Matrix computer that represents the braille character that is being reproduced visually. LCO screen that allows you to see the status of the device and its settings, such as the battery level, selected playback mode (manual or automatic) and language. In addition, the characters that are played in Braille appear in ASCII mode. 10 The solenoids will be the electronic and mechanical elements capable of representing the matrix of points that represent the braille character in relief so that the characters can be read by touch. The set of buttons to configure the playback mode of the device and the handling of all functionalities, such as volume, control over playback (forward, stop or reverse), speed and language for audio playback. To establish the communication and transfer of information between the device and the computer, a software has been developed that allows to perform all the features offered by this device, such as loading, viewing and deleting documents in the device memory, selecting the audio language and handle different options on documents. 25 This information may be any text document that we have on the computer and in different formats, such as pdf, doc, docx or txt. The microcontroller will be in charge of transforming these documents loaded into the memory of the device to braid and reproduce it using the LEDs, the screen and the braille points. 30 BRIEF DESCRIPTION OF THE DRAWINGS To complement the description that is being made and in order to help a better understanding of the features of the invention, an integral part of said description is attached, a drawing where illustrative and not 5limiting, the following has been represented: Figure 1.

Top view of the 2x3 array of solenoids that reproduce the Braille characters. 65 PREFERRED EMBODIMENT OF THE INVENTION A practical example of the use of the Portable Digital Document Reproduction Device in Braille would be: 1. We connect the device to a computer through the USB port and press the upper left button to establish communication between the computer and the device. 2. Once connected, we can open the device software on computer 10 to access the content stored in its internal memory and manage it as follows: 15 20 25 30 35 a. Upload new documents for reading. b. Get a list of all the documents that the device has stored. In this list you can select a document to proceed with its reading. C. The device has a loudspeaker that reproduces in real time the characters that are being played, by means of the software you can also set the language to play the characters that are played by the audio. d. Another of the information we can find in the software is: i. The document that is currently selected for reading. ii. Know the position of the current reading. iii. The selected audio language. iv. Know the last book removed from the device with the possibility of recovering it. and. Set up the Wi-Fi connection so you don't have to connect the device using a USB connection, but rather communicate wirelessly. 3. Once the documents are loaded and one of them is selected for reading, you can disconnect the device from the computer and turn on the device. 4. Using the device buttons, playback can be controlled. In Figure 1 you can see the matrix of buttons named from "A" to "F" with the following functionality: 75 10 15 20 25 30 35 A. It is a switch button, which when pressed allows the device to connect to the device software and stops playing Braille characters. When the button stops pressing, the device restarts, loading all the new information that has been supplied to it from the PC. B. It is a push button in charge of the playback speed of Braille characters. This button allows you to vary the speed in 5 different speeds, with O being the lowest speed and 4 the highest. Speed refers to the time pause between the reproduction of one character and another. These intervals are 2000ms, 1500ms, 1000ms, 500ms and 200ms, these time intervals corresponding to the speeds of O to 4 respectively. This speed affects only affects when the device is in automatic advance mode. C. It is a switch button, which allows the reproduction of sound through the speaker that has the device integrated. When the button is pressed, the sound stops emitting and while the button is not pressed, the speaker reproduces all the characters that are being read by sound. This functionality is useful for the learning of those blind people who have not yet mastered Braille and cannot see the LCD screen. D. This switch button is responsible for pausing playback. When this button is pressed the playback of Braille characters stops being in pause mode. When it is pressed again, the button is released and puts the play in forward or "play" mode. E. It is a switch button, which allows you to configure the playback mode of the device. This reproduction can be automatic or manual. If the button is not pressed, the playback is automatic, which means that the characters are read according to the speed that has been selected with the # 5 button. If the button is pressed, the automatic playback will stop and enter manual advance mode, this means that to be able to advance with the reproduction of braille characters it will be necessary to press button # 6. This functionality has been integrated for people starting at 8Learn Braille and do not master it correctly, since they can advance character by character manually and analyze it completely. F. It is a push button that is responsible for moving from one character to another when manual advance mode is active. Pressing the button passes both the characters and the spaces between words one by one. 10 5. Both characters in the 2x3 LED matrix, and in the LCO screen, as well as through the loudspeaker, the characters that are also being reproduced using the Braille matrix are played in real time. On the other hand, in the LCO screen the current configuration of the device is reproduced as: a. Audio playback language. b. Current playback speed C. Device status, "play" or "stop". d. Type of reproduction, "Manual" or "Automatic" e. Battery charge status. 15 6. Once you have finished reading and you want to turn off the device, you can turn it off at any time, since it saves the current position where you stopped playback, and you can continue reading at any other time. 7. Finally, the device can be connected to the mains at any time to charge its internal battery. 9
