- a source of electrical energy 34 supplying the light sources 35 and the internal resources of the transmitter 29.
- the data are not available. transmitted to the board by modulation of the lighting light but by an infrared transmitter or a low-power radiofrequency link such as Bluetooth.
- Figure 8 illustrates a variant of a double-sided scoreboard. In this variant, it is a question of exploiting the two faces of the electronic board according to the invention by physically positioning it in the premises where it is installed so that the public can visualize its two faces.
- the switchboard is installed between the floor and the ceiling so that the fixture is secure and rigid so that the switchboard does not move and user safety is ensured.
- the table is only suspended from the ceiling, a beam or a bracket or only fixed to the ground on appropriate feet.
- Any physical connections 36 to the power supply network and / or a wired communication network advantageously pass into at least one of the fixing means 37.
- the second face of the board according to the invention is of the same nature, even an exact copy of the main face. In other variants, the second face implements for example different display means such as at least one screen for viewing color videos.
- FIG. 9 illustrates a first variant of the system according to the invention.
- the electronic bulletin board 1 is the place of convergence where the target public can see information produced by different independent entities and possibly distant from each other.
- the invention provides technical means for each of the entities concerned to publish their documents independently.
- a third entity validates a proposed document for that is actually published on the board.
- each department responsible for producing documents 2, 2a, 2b belonging to given categories 24, whose name is displayed for the understanding of the reader publishes directly in the space allocated to it in Table 1 his documents from his workstation, respectively 38, 38a, 38b.
- the concerned contributor accesses the space of the table which is allocated to him by means of a standard web browser on his workstation, from his home or moving.
- An administrator is in charge of configuring the table that he manages also remotely from his workstation 39, or by means of a tablet or smartphone that can connect directly to the board by Bluetooth or WiFi for example.
- the table administrator defines by example the general information displayed 40, the spaces allocated on the board to each authorized contributor, the identifiers and the passwords, the access web addresses and the information of type category 24 displayed, etc.
- the administrator also has access to the setting of the time and date, statistics on for example the duration of exposure to the public of each document, numbers and timestamps of consultations etc.
- This example also implements a web server function that consolidates all the information displayed and / or displayable in Table 1 and makes it accessible remotely to users on a standard terminal 41 through a dedicated web address in Table 42.
- the web address of the table is displayed on the at least one display surface and is therefore easily modifiable by the administrator but this constant information occupies the display surface that may be more useful for other information that is why some variants opt for example for a mention of the web address on a label affixed to the frame of the table or on a cartel, or on another printed display area, or on a dedicated low-cost alphanumeric display that is integrated into the table frame.
- the web server function preferably multi-instanciable, is embedded in the table. It is however preferred to deport the execution of web servers intended for users on remote machines to increase the number of simultaneous consultations at lower cost and lower energy consumption for the table according to the invention.
- Figure 10 illustrates a second system variant according to the invention involving a plurality of electronic bulletin boards 1, 1a, 1b.
- This example of implementation of the invention is representative of a case of use in business where several sites are required to make available to staff tables to bring to their attention legal or regulatory information.
- these tables are placed in places of the buildings where they are easily searchable, typically in obligatory passages such as accesses, entrance halls, etc.
- the frequency of exposure of the personnel to the information displayed is all the greater as the table includes functions and / or information required or of particular interest such as access control and / or working time.
- the menus of the company restaurant information offering privileged conditions for staff to access goods or services etc.
- the personnel department directly manages the functions and services that concern it.
- a person in charge of pay administers the time management functions 43 embedded in the tables by an appropriate link between the table and the information system concerned. 44 Another person from the legal service publishes the information. 2 of which she is responsible from her workstation 38. A person in charge of another field, publishes and administers the documents 2a which concern her on her workstation 38a, a trade union organization publishes and administers its documents 2b by intermediary of one of its terminals 38b from its premises etc.
- FIG. 11 illustrates a first modular array variant composed from the following modules: a C3-format module 45 which is ideal for displaying A4 documents at scale 1, including a touch-sensitive electronic display subsystem at high resolution bistable; two modules 46, 47 in C3 format which is suitable for displaying printed A4 paper; a module 48 in C4 format for displaying a screenprinted print; a module 49 in C4 format for the management of working time, two modules 50, 51 visible long-range display in banner format whose length is equal to that of a module C3 in landscape format and whose height is specific; a frame 52 for the lateral mechanical protection of the modules of the table, for the material support of the aesthetics of the product and for the display of the trade mark 53.
- a C3-format module 45 which is ideal for displaying A4 documents at scale 1, including a touch-sensitive electronic display subsystem at high resolution bistable
- two modules 46, 47 in C3 format which is suitable for displaying printed A4 paper
- a module 48 in C4 format for displaying a screenprinted
- FIG. 12 illustrates a second modular array variant composed from the following modules: three portrait-oriented A4 format modules 54, 55, 56 comprising a sub-assembly of high-resolution bistable touch electronic display; a photovoltaic power module 28 whose length is equal to three widths of A4 module oriented portrait and whose height is specific.
