Information reproducing device of FIG. 1.

Fig. 1 shows a rail system 10, which comprises two horizontally extending rails 12 and a vertically extending rail 14 and to which an information reproducing device 32 is connected. For example, a shelf 48 of a supermarket preferably includes a plurality of horizontal rails 12 and vertical rails 14. Either the rails 12, 14 on the shelf 48 form a supporting structure or the like

Rails 12, 14 are connected to the supporting structure of a shelf 48 (see Fig. 2). This can be done for example by gluing, screwing or by clamping. The use of the present

Rail system 10 is not limited by being connected by a shelf 48, but may be connected to suitable structures on various occasions. When attached to a shelf 48, FIG. 1 shows a front view of the rail system 10, which means that the shelf 48, which is not shown in FIG. 1, would be partially concealed in FIG. 1 by the rail system.

The horizontal rails 12 show in the plan view of Fig. 1 a the Viewer facing opening area 12a. The opening area 12a is designed such that the horizontal rail 12 is designed as a holder 16 for display devices 18. Fig. 1 shows the one

Viewer facing the front of the display device 18, which includes an E-ink display 19, which for example, prizes or other information of a product.

E-ink displays 19 are display techniques used to attempt the

Imitate appearance of ink or ink on paper. E-ink displays 19 reflect the light like normal paper, so they are passive

(non-luminous) ads that are characterized by a very low

Distinguish power consumption. It is only necessary a power supply when the display of the e-ink display 19 is changed. Advantages of the e-ink display 19 are, inter alia, that an image content due to the small distance of the imaging elements to the surface looks the same from every angle, that the display does not flicker that it is very thin and lightweight and with appropriate design also flexible to produce , and that the E-Ink Display 19 in both normal room light and in bright

Sunshine is easy to read, since the imaging elements are reflective.

The display devices 18 are clamped but still slidably received in the horizontal rails 12. This creates the possibility that the display devices 18 can be placed at preferred variable locations of a shelf 48. This is important because depending on the nature of the products on the shelf 48, a position of the display device 18 must be changed.

The display devices 18 optionally show the price

Item description or the price and item description. It is also possible that special promotions can be displayed. To increase the

Customer attention can be given a multicolored display of information as needed. A number of the display devices 18 within the holder 16 of the horizontal rails 12 is free in principle selectable and ultimately present only limited by a physical space requirement of the display devices 18, ie that the display devices 18 can not be pushed together or one above the other. A maximum number of the display device 18 per horizontal rail 12 is thus the quotient of a lateral extent of the opening area 12a and a lateral extent of the display device 18. In the present case, all display devices 18 have the same spatial dimensions. However, it is also possible to provide the display devices 18 with different spatial dimensions, in particular different widths.

In Fig. 1, a first projection 20a and at a lower edge of the horizontal rail 12, a second projection 20b are formed on an upper edge of the horizontal rail 12, which extend along an extension direction of the horizontal rail 12 and the opening portion 12a limit and underlying areas of the cover horizontal rail 12. FIG. 2 shows that the projections 20a, 20b, together with the horizontal rail 12, respectively enclose a rectangular space area 22, so that electrical conductors 24a, 24b are received in a clamping manner in this rectangular space area 22. Hereinafter, the electrical conductor disposed between the upper projection 20a and the horizontal rail 12 will be referred to as the first electrical conductor 24a and the electrical conductor disposed between the lower projection 20b and the horizontal rail 12 will be referred to as the second electrical conductor 24b , In Fig. 1, the electrical conductors 24a, 24b are not visible because they are hidden by the projections 20a, 20b. As a result, a visually appealing appearance is created for the viewer, since running cables generally do not give a high-quality impression. At the same time it is nevertheless ensured that the electrical conductors 24a, 24b with the

Display devices 18 come into contact, so that data and energy are transferable, which will be explained in more detail below.

By means of the at least one vertical rail 14 is a connection created between one or more horizontal rails 12, which are arranged offset parallel to each other. An opening portion of the vertical rail 14 is located on a side facing away from the viewer, so that a visually high-quality appearance results. In an inner region of the vertical rail 14 further electrical conductors extend, the conductors running in the vertical rail 14 in each case the first electrical conductor 24a of a horizontal rail 12 with a further first electrical conductor 24a of a further horizontal rail 12 and in each case the second electrical conductor 24a a horizontal rail 12 with another second electrical conductor 24b of the other horizontal rail 12 connects.

In Fig. 1, the rail system 10 with two horizontal rails 12 and a vertical rail 14 is shown. However, this is not intended to be limiting. Depending on requirements, the rail system 10 can be modularly extended by means of further horizontal and vertical rails 12, 14. In order to connect the individual horizontal and vertical rails 12, 14 with each other, a, in the plan view T-shaped, connector 26 is inserted. The T-shaped connector 26 is hereby means

mechanical clamping in the rails 12, 14 inserted. The T-shaped connector 26 includes metallic pins 28, these metallic pins 28 forming the abovementioned connection of the first leads 12 and the second leads 14 of the horizontal rails 12 by forming a common contact surface therewith. Here are the

metallic pins 28 slidably received within the T-shaped connector 26; are the metallic pins 28 in a disengaged position, these make the connection between the rails 12, 14 ago. In an engaged position of the metallic pins 28, the T-shaped connectors 26 may be used as the end pieces 30, as shown in FIG. The two connecting pieces 26 in FIG. 1 each show on the side facing the horizontal rails 12 the metallic pins 28 in a disengaged position and on the side facing away from the horizontal rails 12 the metallic pins 28 in an engaged position. 2 shows a side view of the information display device 32 and the rail system 10. In the side view it can be seen that the horizontal rail 12 forms a C-shaped profile with flat outer sides 34. The first projection 20a and the second projection 20b define the opening portion 12a, wherein a first slot 36a is incorporated in the first projection 20a and a second slot 36b is formed in the second projection 20b. The slots 36a, 36b are configured in such a way that a transparent protective film 40 can be inserted into the slots 36a, 36b, which protects the e-ink display 19 of the display device 18 and the conductors 24a, 24b and at the same time provides a viewer with a view of the display device 18 not disabled.

Perpendicular to the direction of extension of the horizontal rail 12, the projections 20a, 20b have a length that is substantially one each

Diameter of the first electrical conductor 24a and a diameter of the second electrical conductor 24b correspond. The space region 22 between the projections 20a, 20b and the horizontal rail 12 is further formed so that the first electrical conductor 24a and the second electrical conductor 24b are clampingly received between the rail 12 and the respective projection 20a, 20b and thereby prevented from view of the Observers are hidden so that the C-shaped profile forms a bracket 38.

In the present case, the display device 18 comprises the e-ink display 19, which is received and held in a clamping manner between the first conductor 24a and the second conductor 24b by its own curvature. In this case, the e-ink display 19 and the electrical conductors 24a, 24b are interconnected by means of at least one contact point 44, so that data and energy can be transmitted through the electrical conductors 24a, 24b to the display device and thereby to the e-ink display 19.

On the side facing away from the viewer of the horizontal rail 12, a first adhesive layer 46 a is attached. By means of this first adhesive layer 46a, the horizontal rail can be attached to a shelf 48, so that the e-ink display 19 is arranged at an angle α of 0 degrees to a viewer.

However, if the e-ink display 19 is well below an eye level of the observer, a viewing angle α of greater than 0 degrees is advantageous. For this purpose, an adapter wedge 50 is attachable to the first adhesive layer 46a, wherein on the first adhesive layer 46a opposite side of the adapter wedge 50, a second adhesive layer 46b is mounted, which in turn is connected with its side facing away from the adapter wedge 50 on the shelf 48. Depending on the shape of the adapter wedge 50, a desired viewing angle α for the e-ink display 19 can thereby be set.

Fig. 3 shows a hierarchy tree of a data communication device 52 with the information reproducing device 32 of Fig. 1 and Fig. 2. Data, which may be, for example, purchase prices of a supermarket for labeling various products, by a user in a branch on a computer 56 with a server-like System edited and deployed. Here, the data communication device 52 is not limited to the application in a supermarket, but may be used for numerous applications in which display devices 18 are to display variable contents which are flexibly controlled by a central computer 56. So it goes without saying that the data does not necessarily have to be processed via the computer 56 in a branch, but that the alternative case is included, that the

necessary data are transmitted from a central office to the individual branches.

The data is transmitted by the computer 56 to a first industrial radio module 58, which transmits the data by means of radio signals 60 with a frequency of 868 MHz and a range of 15 meters in different spatial directions. The radio signals 60 are sent to at least one access point 64, each access point 64 having a second industry radio module 62 with which the radio signals 60 are received. Furthermore, the access point 64 includes a first infrared module 70, a power supply 66 for the Power supply and a microprocessor unit 68 for processing and buffering the data transmitted by the radio signal 60. The at least one access point 64 has the data at least one

Master module 72 by the data by the first infrared module 70 of the access point 64 to a second infrared module 74 of the master module 72 are sent. The number of master modules 72 and access points 64 is arbitrary in principle, with more master modules 72 than

Access points 64 are used, thus a parallelization and

Simultaneity of the data transmission can be ensured, which increases the effectiveness of data transmission. In FIG. 3, two access points 64 and three master modules 72 are provided by way of example. The access points 64 can in this case, for example, on the ceiling of a

Room are attached and from this position the data to the

Send master modules 72, which are connected to the shelves 48. The data transmission between the access points 64 and the master modules 72 via infrared signals 76 is more power-saving than a data transmission via

Industrial radio. Furthermore, the infrared modules 70, 74 are less expensive than corresponding radio pendants. In general, nevertheless, become common

Radio signals used, as they can easily overcome obstacles due to the smaller wavelength diffraction reasons, which are arranged between a transmitter and a receiver. However, this is bypassed in the present case. As already indicated, an arrangement of the access points 64 on the ceiling and a connection of the master modules 72 in upper areas of the shelves 48 creates a situation in which no objects interfere with the infrared transmission. The data for controlling the display device 18 are thus transmitted from the first infrared module 70 of the access points 64 over a short distance to the second infrared module 74 of the master modules 72.

The master modules 72 also include a further microprocessor unit 78, which processes the data, a battery 80 which provides low voltage and an interface 82 which allows connection to the first electrical conductor 24a and to the second electrical conductor 24b. Via junctions 84, a branching of the electrical conductors 24a, 24b is made possible, so that they can be connected to a plurality of rows 86a, 86b, consisting of a plurality of display devices 18. In Fig. 3 are each a first row 86a and a second row 86b with several

Display devices 18 via the electrical conductors 24a, 24b with the

Master module 72 connected. Here are along the rows 86a, 86b

Wildcard symbols 87 entered. The wildcard symbols 87 are

to be understood that instead of the placeholder symbols 87, further display devices 18 along the rows 24a, 24b may be connected. The batteries 80 of the master modules 72 at the same time provide a power supply to the display devices 18. Advantageously, in the event of failure of the battery 80, no battery element needs to be replaced on each individual display device 18, but only the battery 80 which is connected to the master module 72. As a result, both a workload when replacing the batteries 80 is reduced and at the same time reduced production costs, otherwise each display device 18 must be provided with its own power supply. In addition, a power consumption of

Display device 18 and the master module 72 so low that the battery 80 must be replaced in average only about once a year. If this replacement operation is also undesirable, the battery 80 can be replaced, for example, by a rechargeable battery which can be charged by a solar cell module, which is additionally connected to the master module 72.

The electrical conductors 24a, 24b thus connect the display devices 18 to the master modules 72, wherein both control data and the energy for the display devices 18 are transmitted by the electrical conductors 24a, 24b. For this purpose, the second electrical conductors 24b form the reference potential designed as a ground. The data and energy transfer takes place via the first electrical conductor 24a via a so-called single-wire bus technology in the bidirectional half-duplex method.

The single-wire bus describes a serial interface that manages with a data wire, both as a power supply as well as transmitting and

Receiving line is used. The single-wire bus is misleading, because in addition a ground connection is required, which in the present case is formed by the second electrical conductor 24b. Preferably, the single-wire bus is operated with an operating voltage between 2.8 V and 12 V. The

Current consumption of single-wire bus devices is between 2 μΑ and a few mA.

The bidirectional attribute means that a data transmission in both directions takes place point by point. The term originally comes from the radio transmission, in which signals simultaneously in both directions

could be exchanged. If one can both receive and send data with an interface 82, then this interface 82 is referred to as bidirectional. If data is transferred to the same medium in both directions at the same time, this is called a full duplex method. One-way transmission at a time is called a half-duplex method.

The essential components of the display device 18 are shown in Fig. 4. Both the first electrical conductor 24a and the second electrical conductor 24b have their origin in a symbol in FIG

Battery 80 represents. The symbol to the left of the battery symbol 80 is intended to show that the data transmission also originates from this connection point of the electrical conductors 24, 24b. The first electrical conductor 24a branches off the battery 80 and contacts the display device 18 at a first contact node 90. The second electrical conductor 24b also leaves the battery 80 and contacts the display device 18 via the second contact node 92 and the third contact node 94. The

Display device 18, which may be in the form of a flexible label is formed is held by the first, second, third contact node 90, 92, 94 by means of its own spring force clamping and readily displaceable in the form of a three-point system between the first electrical conductor 24a and the second electrical conductor 24b horizontally displaceable. Here, the contact nodes 90, 92, 94 are formed as elevations 90, 92, 94 of the flexible label.

The energy and data are transferred via the first contact node 90 into an amplifier and filter circuit system 96 of the display device 18. The amplifier and filter circuit system 96 includes suitable resistors 98, a capacitor 100, and a transistor 102 for processing and utilizing the data and power. Product designation information desired by the user is forwarded by the amplifier and filter circuit system 96 to a logic unit 104, which controls the display 19, which is designed as an e-ink display 19, wherein the energy supply of the e-ink display 19 at the same time by the first electrical conductor 24a is provided. In the present case, the logic unit 104 is designed as a display driver 104. Each display device 18 has its own fixed address and waits for a direct response by the master module 72. The e-ink display 19 requires only during a change in its display minimum currents and is otherwise in a standby mode, which virtually no power consumed, so that even in case of failure of the battery 80, the e-ink display 19 continues to distinguish the price of a product.

FIG. 5 shows an alternative embodiment of the master module 72. In this case, the master module 72 comprises, in addition to the second infrared module 74

Cable connection 108 and a third radio module 1 10. This is

allows the data transfer does not have to take place via the infrared module 74, but that, for example, the master module 72 is connected by means of the cable connection 108 to the access point. Alternatively, the master module 72 can also be connected directly to the computer 56 by means of the cable connection be connected and receive the control data for the display device 18 directly. In addition, the power supply may be provided by the cable connection 108 so that the master module 72 no longer needs a battery 80. As an alternative, the data transmission can also be carried out via the third radio module 1 10, so that a direct connection between the computer 56 and the master module 72 can be produced, so that the access points 64 can be dispensed with.

The invention now works as follows:

First, the rail system 10 is aligned on a shelf 48 that the products to be labeled above or below the

Rail system 10 are located. In a next step, a display device 18 is selected for each product to be designated, which is designed as a flexible label, so that it can be curved by staff for insertion into the rail. When the display device 18 is in the rail, the operator reduces the pressure on the display device 18, so that the curvature decreases and the display device 18 tends to form a flat surface again. Here is the

Display device 18 with its upper end in contact with the first electrical conductor 24a and at its lower end with the second

electrical conductor 24b. By the force of the display device 18, which counteracts its own curvature, a contact pressure on the first electrical conductor 24a and the second electrical conductor 24b is generated, which can be seen in Fig. 2. By a separate spring force of the display device 18, the display device 18 is clamped and at the same time horizontally slidably received between the electrical conductors 24a, 24b, wherein the

Display device 18 is so connected to the electrical conductors 24a, 24b that an energy and data transmission can take place.

The data to be processed by a user by means of a

Graphical user interfaces on the computer 56 prepared and by means of

Radio signals 60 sent to the access points 64. Generally, that is one Data transmission via infrared has a lower data rate than a radio link, but by the radio signals 60 are transmitted to multiple access points 64, which in turn the data to several

Send master modules 72 via infrared signals 76, a parallelization of the data transmission is possible, which is able to increase the data transfer rate. In this case, the access points 64 store the received data of the computer 56 and constantly send them to the master modules 72. If all the data has been correctly transferred from the computer 56 to the access points 64, the computer 56 receives a confirmation via the

successful transmission of the data and, if applicable, a corresponding error code if the transmission was carried out incorrectly.

The master modules 72 distribute the data to the display devices 18 via the first electrical conductor 24a by a single wire bus technique in bidirectional half-duplexing, the data being modulated onto the first electrical conductor 24a by voltage modulation.

Each display device 18 has its own fixed address and waits for a direct response by the master module 72. A defined

Data protocol ensures the correct data transmission and display through the E-Ink Display 19. The second electrical conductor is here as

Reference potential formed.

The display device 18 evaluates the voltage differences through a corresponding amplifier and filter circuit system 96 and executes corresponding commands. Here everyone always receives

Display devices 18 the data, but only the ones react

Display devices 18, which are addressed by the corresponding address information in the transmission protocol.

In turn, the display device 18 returns feedback by a defined load of the first electrical conductor 24a (for example, by generating a 20 mA current flow in the data clock). Hereby sends always only a single display device, and only if there is no further information on the first electrical conductor 24a. The master module 72 in turn detects this current flow and prepares again data from these current changes, which in turn are sent to the computer 56 and confirm successful display on the e-ink display 19.
