Abstract

In a method of communication for the transfer of data for an electronic microdevice (1) using a user interface realized in a display device (2) for the representation of data of the microdevice (1) by means of a script-based browser that retrieves files as units of information from within a script, and by means of a data transfer protocol, a middleware (4) is used. This middleware (4) has on the one hand a first communications link (EK) to the display device (2) and on the other hand a second communications link (ZK) to the microdevice (1), the rate of data transfer in the second communications link (ZK) being lower than that in the first communications link (EK), and the computing power and memory of the microdevice (1) being lower than the computing power and memory of the middleware (4). The method transfers data assigned to the microdevice (1) to the display device (2) via the middleware (4), while data from the microdevice (1) are transmitted for transfer to the middleware (4), synchronously or asynchronously in advance. In this process the data to be transferred are adapted in such a way that the middleware (4) provides a file that is specific to the microdevice (1) and to the display device (2), and this specific file can be associated with the microdevice (1) by the display device (2) by virtue of the file designation, so that a processing by means of script-based browser becomes possible and the middleware (4) defines for the display device (2) the functional interface to the microdevice (1).

Claims

1. Method of communication for the transfer of data for an electronic microdevice (1),

with

a user interface realized on a display device (2) for the representation of data from the microdevice (1) by means of a script-based browser retrieving files as units of information from within a script, and by means of a data transfer protocol, where microdevice (1) and display device (2) can be positioned locally independently of each other,

a middleware (4) which can be connected,

on the one hand via a first communications link (EK, EK′

) with the display device (2) and

on the other hand via a second communications link (ZK, ZK″

) with the microdevice (1),

where

the data transfer rate of the second communications link (ZK, ZK′

) is lower than that of the first communications link (EK, EK′

), and more particularly lower than 3 Mbps, and

computing power and memory of the microdevice (1) are lower than computing power and memory of the middleware (4), the memory in particular being less than 100 kB,

and at least the steps

transfer of data assigned to the microdevice (1), to the display device (2) via the middleware (4), where the data are transmitted from the microdevice to the middleware (4) for transfer, synchronously or asynchronously in advance, wherein

an adaptation of the data to be transferred occurs in such a way that the middleware (4) provides a file that is specific to the microdevice (1) and to the display device (2),

this specific file being assignable to the microdevice (1) by the display device (2) in view of the file designation, so that a processing by means of a script-based browser becomes possible and the middleware (4) defines display device (2) as the functional interface to the microdevice (1).

2. Method of communication according to claim 1, wherein

data to be transferred from the microdevice (1) during adaptation are supplemented by the middleware (4) with further data, these supplements being retrieved by the middleware (4) from a memory unit (5) that is independent of microdevice (1).

3. Method of communication according to claim 1, wherein

the middleware (4) during adaptation simplifies the data transfer protocol for the microdevice (1), particularly by reducing it to a subset of the hypertext transfer protocol.

4. Method of communication according to claim 1, wherein

the middleware (4) during adaptation converts the data to be transmitted, in particular by data compression or data decompression, in order to generate the specific file.

5. Method of communication according to claim 1, wherein

the middleware (4) during adaptation generates data structures adapted with a view to microdevice (1), in particular by setting up a web server data structure consisting of just one default file and one zipped file, the zipped file containing script files such that when answering a request from the display device (2) to the microdevice (1), the middleware (4) automatically retrieves and unzips the zipped file.

6. Method of communication according to claim 1, wherein

the middleware (4) during adaptation undertakes a data caching for microdevice (1).

7. Method of communication according to claim 6, wherein

a hash value is added as file designation to or included in the file name or a corresponding address designation in the Internet (6), so that a well-defined referencing including integrity check is possible.

8. Method of communication according to claim 7, wherein

the hash value is computed from the content of the file including file name and file type extension, and is appended to the file name.

9. Method of communication according to claim 1 wherein

the memory of the microdevice (1) is 32 kB at most, and the data transfer rate in the second communications link (ZK, ZK′

) is 9600 bps at most.

10. Method of communication according to claim 1, wherein

data are transferred from the display device (2) to the microdevice (1) via the middleware (4).

11. Method of communication according to claim 1, wherein

the first and/or second communications links (EK, ZK) are realized via the Internet.

12. Method of communication according to claim 1 wherein

the middleware (4) is implemented in the display device (2).

13. Method of communication according to claim 1, wherein

the middleware (4) is implemented in a UBS adapter.

14. Method of communication according to claim 1, wherein

an inclusion of functionalities of the microdevice (1) into applications in the Internet (6) is brought about by the display device (2).

15. Computer program product with program code that is stored on a machine-readable support or embodied by an electromagnetic wave, for carrying out the method according to claim 1, in particular when running the program on a computer.

16. Data structure product for carrying out the method according to claim 5, comprising one default file and one zipped file, the zipped file containing script files such that when answering a request from the display device (2) to the microdevice (1), the middleware (4) by retrieving the default file automatically retrieves and unzips the zipped file.
