Description

COMPUTER WITH MULTIPLE SCREENS

FIELD OF THE INVENTION

Computer with multiple screens, of the type that has a central control unit to be used by an operator, with data input means such as a mouse and keyboard, and a screen for displaying images that said computer processes, with the particularity that it has at least one additional screen on a separate display device, with data input and output means, which with different ways of linking with the computer structure allows interactive and independent viewing of images of the main computer.

BACKGROUND

Personal computer systems are known that when connected forming a network can share applications that may or may not be distributed among the terminals of said network. In this architecture, the terminals have greater or lesser processing capacity and storage or peripheral media, depending on the philosophy of the network, centralized or not, but it is always required that each terminal have a microprocessor and its own personal computer structure.

The computer provides the centralized data according to patterns that are read and interpreted by the microprocessors of each terminal and treated according to their own interfaces to manipulate this type of data object. Users can interact with said data and send and receive additional information in an interactive communication between terminal and main computer.

Said solution is not drawn as the most appropriate in those contexts in which the agents who use secondary positions are required to have a certain degree of mobility and independence. Playing a complete PC at each station is unnecessary for a large number of situations. And even with the continuous lowering of the manufacturing costs of PCs, it also represents a high cost of the whole, not only in machinery but also in software licenses for each terminal.

On the other hand, the existence of Personal Computers or PCs that have bifurcations in their video output is also known, so that they can display the same image on one or more screens. Even, the possibility of having different video outputs is also well known from the Technique, by installing different video cards in the PC, so that different images can be displayed on each screen. For example, the source code of a program in one, and its result as a running program in the other.

The latter type of screens can be used to support training, product demonstrations, etc., since they allow whoever controls the PC to decide that Information is displayed on the screen or additional screens. For example, in a sales context, the user could be viewing a spreadsheet with details of commercial margins, sales volume, stocks, etc., referring to a commercial product, while the secondary screens to be displayed by customers show graphics and characteristics data of said products.

An improvement of said previously described situation consists in providing some kind of interactivity to said secondary screens, so that they actually develop a system of slave terminals through which users can interconnect with the PC.

DE ske patent DE19616029 develops a device for interactive transmission between two channels of interlocutors in which the flow of information is influenced by one of them. The realization is achieved by dividing the video output of the computer into two paths, one to the monitor of the owner of the information and the other to the additional screens, in the second path an information filter is inserted that shows it according to priority signals. of said information collated with the privileges of its recipients.

The previous application supports user operability through data input or control devices, such as a keyboard or a mouse, it supports that the second screen is physically separable from the computer main and even that is communicated with it by wireless signals. Still, it should be noted that said additional screen is the same screen as that of the main computer which has been deprived of access to certain information according to a filter that selects said information. It is not properly an additional interactive display device, but a mirror of the unique screen of the system that has been equipped with selective blocking of information.

Milner PCT patent WO99 / 04686 develops a system to provide an interpreter means of communication between physician / healthcare provider and a patient having difficulty communicating. The device is a personal computer with an additional touch screen, physically articulated with the former by means of an extendable arm. The patent develops a Friendly Graphical Inferior (GUI - Undersable Graphical Interface) to facilitate communication with the disabled and inexperienced patient with computers, so that with concise questions he can transmit his needs to his caregivers and even communicate with his family members.

Janicek's US patent US6366450 develops a bay for PDAs (Personal Digital Assistants) which are handheld computers with a similar architecture to a PC but smaller in size, lower consumption capacities and input means and Visualization of reduced data, due to the needs of its size. Through this accessory, the PDA can receive power from a Conventional power for use and / or charge your batteries.

Nahi Patent Document US6166734, Paul B. develops an interactive multiple display system for a personal computer. On this occasion there is a PC that serves the data to the screen of said computer, and an undetermined number of auxiliary display devices connected to the PC by wireless means, said devices also presenting data input and output means.

The device of the invention of document US6166734 pursues the distributed communication of an application between dispersed agents. The aim is to simplify the construction of the computer terminals known in the art, as well as to provide them with wireless communication means, which are radio communications, to facilitate their portability.

All the devices, systems and apparatuses described, even with their advantages in the fields to which they are intended, do not in any case provide a multiple-screen computer of the type developed by the present invention, which allows both different ways of linking said screens with the main computer screen, such as being used remotely through wireless communications, being governed by means of an array of field programmable gates (FPGA) that relates its different modules. With this, not only is an efficient and economic design of the proposed purpose achieved, but due to its own characteristics, an optimal configuration of size, weight and consumption is obtained, in a product that is enormously more versatile in terms of use than any of those contemplated. by the prior art.

In reality, the capacity of said interactive display device goes beyond receiving images from a computer (1), which is the main object of the invention. You can also receive images from another sender, such as a central computer, a digital TV, a video, or a PDA (Personal Data Assistant - also known as a handheld computer).

The display device (3) can accept instructions from the user through the same screen (6) designed as a touch screen or by means of a keyboard or mouse, it has the capacity to reproduce sound and receive oral instructions.

The additional interactive display device (3) can be connected to the computer (1) or another image transmitter by cable or by wireless connections of any kind. There are also different linking and / or physical relationships between the screen (2) of the computer (1) and said interactive device (3).

An FPGA (5) is a chip that can be programmed to implement a specific digital circuit and is equivalent, once said implementation is made, to said digital electronic circuit.

For this purpose, the implementation of different communication protocols such as IEEE 802.11a, IEEE 802.11b, IEEE 802 Alg, Bluetooh, UMTS, etc. has been provided in said communications module (7), and can be easily adapted to any type of protocol. of communications.

For example, the preferred embodiment envisages the use of PCMCIA or Compact Flash sockets, the future technical developments of these input ports being considered included in the invention. The communication cards that establish the desired protocol are located in these sockets. In this way, different communication protocols such as GPRS, UMTS, etc. can be used, changing the corresponding PCMCIA or Compact Flash card. In addition, the implementation of this type of PCMCIA or Compact Flash sockets or equivalents of removable card input ports in the communications module (7), allows incorporating into the present invention any type 5 of future performance that may be contemplated with said type of cards, obtaining a product, open and expandable in the future.

In strict terms, the present invention realizes a multi-screen computer (1) capable of displaying graphics sent from said computer (1) or another image emitter, such as a main computer or a TV receiver or video transmitter, interact with them independently in each interactive display device (3) returning to the computer (1) the user's input and data manipulation.

• • For -the transmission optimization has been chosen- because the communications module (4) implemented in the

The computer (1) transmits compressed images or portions thereof.

The interactive display device (3) receives from said computer (1), by means of the 25 communication adapter module (4) implemented therein, compressed screens or compressed images of portions of a screen and that the device of the invention ( 1) dumps by means of the appropriate commands preprogrammed in the FPGA (5) to the screen of the device (6).

30 So although initially the preferred embodiment of the invention provides sufficient RAM (9) to storing at least two screen images, the current one and the one that is built, only needs to generate the portion of the screen that has undergone a modification.

Specifically, the preferred embodiment of the present invention implements MEPG-type compression for video, with plans to adopt future evolutions of said standard.

In the event that wireless signal fails or is not received properly, or ^'simply communicate not wish to emitter images, in one of the embodiments of the invention, for example in cases where the communication It is wireless, the additional interactive display device (3) can continue the image processing autonomously to the image emitter due to the embedded field programmable gate array device - FPGA (5).

The device (3) accepts user information by its data input module (10) by different means. Mainly through commands to said device through the touch panel of the LCD screen type TFT (6), also through verbal instructions interpreted by voice recognition systems, by graphs that are interpreted by character recognition techniques, and finally by any known means of data entry.

These inputs are processed and analyzed by the FPGA (5) and transmitted, when appropriate, to the communications (7) to be sent to the communications adapter module (4) of the computer or image sender (1), for encoding.

The preferred embodiment of the present invention envisages the use of batteries (16) for powering (15) the display device (3). For example, when you are wireless. According to the Known Technique, a support or bay (17) can be provided to support the display device (3) and simultaneously receive electrical power from the network. Said bay (17) may, when deemed convenient, be provided with the suitable cable connections to link with the communications module (4) of the computer (1), without altering the essence of the invention.

In accordance with what has been previously described, the display device (3) has a multi-media module (12) and a data entry module (10) to display, manage, record and store multimedia information of video, sound and images. The possible use of an additional keyboard and even the connection of a mouse by any of the known means has been foreseen.

From a physical functional point of view, according to certain practical embodiments of the invention in which the image emitter is a personal computer (1), different structures can be found between said personal computer (1) and the additional display device (3 ). First, the display device (3) can use wireless connections and be located independently of the computer (1) or image emitter, being separate from it. This embodiment is suitable both if the image emitter is fixed type desktop PC or TV, or if it is a portable image emitter, such as a laptop, a personal assistant PDA or other similar mobile solutions.

In these latter cases, for example, with a portable image emitter (2), the device of the invention (1) should be prepared to be packed in the structure of the portable computer to be transported as a single set.

In an alternative arrangement of the present invention, ideal for, but not limited to, personal desktop computers, the display device (3) is used as an auxiliary terminal to facilitate data entry, for example, by means of recognition software. conventional writing, signs, voice recognition, etc .; The device (3) is arranged resting on the same table or support surface of the keyboard of the main computer (1), being attached to the monitor or screen (2) thereof by any connection, such as by means of articulation.

In the examples described above, the connection of the display device (3) with the main computer

(1) allows you to dispense with wireless communications and instead use wired communications that they run through the articulation means that connect the device (3) with the main computer (1).

As already repeatedly described, the present invention allows different types of practical embodiments using different means for articulation between the main screen (2) and the independent display device (3).

EXAMPLE 1: SUPPORT PLATES

The characteristic of said embodiment is the use of two intermediate support plates (18 and 19), hinged to each other by a hinge (20), one of said plates also being hinged to the base of the computer (1).

The computer screen (1) and the independent display eG ti VG (3) are hinged to the upper edges (21 and 22) of the intermediate plates (18 and 19).

In this way, a relative positioning of the main screen (1) with respect to the independent display device (3) will be achieved with the rotation of the intermediate plate (18) on the hinge (23) of union with the console or central unit of the computer (1).

Another movement and its resulting positions are achieved by rotating the intermediate support plate (19) on the hinge (20) of articulation with the intermediate plate (18). Additionally, each of the screens can rotate on a horizontal axis around the upper edges (21 and 22) of the intermediate plates, respectively (18 and 19).

As the graphics accompanying the present description show, with the described embodiment different working positions can be obtained between the screen (2) of the main computer (1) and the independent display device (3). For example, by folding the intermediate plates (18 and 19) with the screens (2 and 6), this results in the folding of the computer as shown in Figure 9, in a compact format suitable for transport.

Said intermediate plates (18 and 19) are obtained by -division of a single plate -in two parts by a cut line on which both the lower cutting edge (24) of the plate (19) and the upper edge ( 24 ') for cutting the plate (18). As a consequence, the intermediate plates (18 and 19) fit into each other. Figures 3 to 9 show different examples of the different positions that can be obtained.

Especially, Figures 7 and 8 in which the two intermediate plates (18 and 19) are hinged at the foot of a base. In figure 10 the auxiliary screen (6) in said independent display device (3) is supported on the work table, and located laterally to the main screen (2) of the computer (1). As shown, said arrangement is suitable for using the independent display device (3) as a data entry tablet, introducing graphs or other signs that said device (3) may be able to interpret.

EXAMPLE 2: SUPPORT TUBES

In this embodiment, the connection between the main screen (2) and the independent display device (3) is made by means of hollow support tubes that can be passed through, when it is considered convenient to connect cables between the computer (1) and the device ( 3) .

Figures 11 to 13 show that the frame of the main screen (2) is essentially made up of a tubular frame consisting essentially of the union of different component parts: the upper frame (25), the intermediate lateral frame (26), the outer side frame (27), the lower side arm (28), the lower intermediate arm (29); together with the support frame of the independent display device (3) formed by the auxiliary upper frame (30), the auxiliary intermediate arm (31) and the auxiliary lateral arm (32). The union is made thanks to an intermediate coupling piece (33) in which the ends (31 or 32) of the auxiliary upper frame (30) can be threaded.

Figure 11 represents the different elements indicated above, separated and in line, to which the back plate (34) and frame (35) of the main screen (2) are added, as well as the back plate (36) and frame front (37) of the independent display device (3), the lower articulation support (38) for articulating the main screen (2) also being shown.

As shown in the detail that constitutes figure 13, the double joint (33) on the side of the frame of the main screen (2) can be made up of one or more pieces that make up a single body with lower cylindrical elements (? 9 ). and higher (40 and 41) for a simple mounting version of the tubular elements (25, 26 and 27).

An alternative form of articulation to the previous one, thanks to the intermediate coupling piece (33), is represented in the details shown in Figures 14 and 15. Here joint pieces (42 and 43) are used, provided with two central bodies with coaxial coupling rods (44 and 45) and plug housings (46), or non-coaxial end pivots (47 and 48) and a plug housing (49), the ends of the respective frames of the screens being able to be coupled to them main and auxiliary. With this last arrangement, the main screen (2) and the display device (3) can be arranged in multiple optional variations, allowing articulation on the sides of the main screen (2) or on the upper side of the auxiliary screen itself or independent display device (3).

Figure 21 shows an embodiment of the present invention in which the main screen (2) is rotatable about a vertical axis, for which it has a pivot joint (50) on its underside that is coupled to a support ( 51) associated with the computer base (1) •

Figures 17 to 20 show articulation variants of two screens respectively on either vertical side of the main screen (2). Thus, the upper frame (25) of the main screen (2) can articulately receive two auxiliary upper frames (30) from two independent devices (3) by means of the couplings (33) that pressure-receive the ends 40 and 41 of these frames.

Figure 18 represents an embodiment in which two independent display devices (3) have been added to the main screen on its sides.

It is understood that in the present case any variation of detail that does not alter the substance is included in the object of the invention.
