In an information management system for handling digital position data recorded by an electronic pen, the pen is controlled to convert recordings of a first code on a product to position data in a coordinate system, to convert recordings of a second code to input data, and to process the position data on the basis of the input data. The input data may define one or more functional areas in the coordinate system, and the pen may map the position data against the input data and take appropriate action if the position data is deemed to fall within a functional area. This allows the pen to be dynamically provided with a description of all or parts of the functional layout of a product, thereby reducing the need of the pen to pre-store such descriptions for all products. Encryption or usage may also be controlled based on data encoded by the second code. The product may be generated, via a computer-implemented method, to include the first code, the second code and any supporting graphics. The input data may alternatively be derived from another import interface of the pen, such as a communications interface or a replaceable memory unit.

Methods and systems for processing digitally recorded data in an electronic pen

The present invention relates to a method in a computer for creating an electronic document to be printed, said document comprising a page description representing a layout of the document, said method comprising: retrieving a license from a database, said license defining a position-coding pattern, which is capable of encoding positions on a product when printed, selecting at least a portion of the position-coding pattern in the retrieved license to be associated with the page description, forming a sublicense from said license, said sublicense comprising a definition of the selected at least portion of the position-coding pattern, an indication of an origin of the sublicense to enable assuring that the sublicense stems from a trusted actor, and a data record allowing verification of integrity of the sublicense to enable assuring that the sublicense has not been tampered with, and associating said sublicense with said page description. The invention also relates to a method for verifying a sublicense to a portion of the position-coding pattern.

Printing of a position-coding pattern

Disclosed methods, computer-readable media, and systems relate to position-coded products and processing data from such products. In one implementation, a computer-readable storage medium stores a program for a computer to perform a method for creating an electronic representation of a position-coded product. The method may access an electronic document file with a set of document pages and map the document pages, copy for copy, within a selected number of copies, to pattern pages according to an ordering of the pattern pages.

Electronic representations of position-coded products in digital pen systems

A computer-implemented method is designed for on-demand printing on digital printers of a coding pattern to code data on a surface. The coding pattern comprises a plurality of parallel number sequences which represent different rotations of a cyclic number sequence. The method could involve retrieving a digital representation of the coding pattern, and identifying the rotations therein to derive shift information which designates a phase difference between each rotation and the cyclic number sequence. In the printing operation, all the different rotations may be represented by the cyclic number sequence embodied as at least one code block image. This code block image is repeated in accordance with the shift information to form a printable image in the printer.

On-demand printing of coding patterns

A computer-implemented method is designed for printing on regular digital printers of a coding pattern consisting of regularly spaced code symbols. In the method, a page-describing code (e.g. in PostScript programming language) is generated for the printer. The generation of the page-describing code is based a character definition set which assigns a set of characters to represent a set of mutually unique groups of the code symbols. By mapping the set of mutually unique groups against the coding pattern, the location of corresponding groups within the coding pattern can be identified. Each of the corresponding groups is then represented by its assigned character in the page-describing code. The resulting page-describing code is small in size and has a reduced set of printer instructions that can be processed efficiently by the receiving printer.

Device for processing of information, which device comprises a processor and, connected to the processor, a reading unit for electronic reading of information on a surface, which is provided with a position code which codes a plurality of positions on the surface. The device reads the position code, associates a position code for coded positions within a value area defined on the surface with values in a set of values which includes a plurality of values, and initiates the generation of a control signal whose level is related to a value associated with a read-off position code. Method for processing of position data obtained from said surface. According to the method, the position code is read for a coded position which lies within the value area; the value in the set of values which is associated with the read-off coded position is determined; and the generation of a control signal is initiated, the level of which control signal is related to the determined value. Computer program for processing of position data in accordance with the method, and a product which comprises a surface of the above-mentioned type. Elected for publication: FIG.

Editing data

The invention relates to a method for controlling a unit provided with a processor. The method includes receiving at least one graphical notation in the form of positions representing a sensor device's movement across a base that is provided with a position-coding pattern, while the graphical notation was made, identifying, based on the at least one graphical notation, at least one command for the unit provided with a processor, receiving an address to the unit provided with a processor, and controlling the unit provided with a processor by sending the at least one command to the address. A computer program product contained within a medium and a device for implementing the method is also provided. The method for controlling a unit provided with a processor uses a sensor device and a product kit for controlling a unit provided with a processor.

Control of a unit provided with a processor

A device, a method and a computer program for position determination are provided. The device comprises a processing means for determining a position on a surface on the basis of an image of a position-coding pattern on the surface. The processing means is arranged to decide whether it is possible to determine an acceptable posi- tion on the surface on the basis of the position-coding pattern in the image. In addition, the processing means is arranged to cause the first writing means to write on the surface depending upon the result of said decision.
