Publication number: 20060007183Abstract: In an input unit arrangement use is made of an input unit in combination with a mouse pad, which is provided with a position-coding pattern which codes coordinates for a plurality of positions on the mouse pad. Areas on the mouse pad are provided with subsets of the position-coding pattern which are dedicated to different functions. The input unit can be caused to optically read the position-coding pattern, whereupon the input unit arrangement decodes the positions that are coded locally on the mouse pad. By placing the input unit within the various areas on the mouse pad, a user can make the input unit arrangement carry out various functions, such as automatically switching from a mouse function, in which a cursor is controlled on a display on the basis of the decoded position, to an input function, in which information via the input unit is inputted into an electronic device, such as a computer, telephone, PDA etc.Type: ApplicationFiled: September 15, 2005Publication date: January 12, 2006Inventors: Petter Ericson, Christer Fahraeus

Publication number: 20050076079Abstract: The invention relates to a method of effecting in a computer system transmission of data between a digital user unit and a computer resource, the user unit being adapted to detect positions on a base which is provided with a part of a global position-coding pattern. The invention is characterized in that a request for access to a computer resource is received, using a first protocol stack, by the computer system from the user unit, said request containing a position indication, relating to which part of the global position-coding pattern that has been detected by the user unit. The computer system gains access to a computer resource using a communication mode and a second protocol stack. The communication mode is chosen based on the position indication. Only the second protocol stack comprises TCP/IP functionality, so that only data transmitted between the computer system and the computer resource comprises routing information.Type: ApplicationFiled: December 27, 2002Publication date: April 7, 2005Inventors: Linus Wiebe, Petter Ericson

Publication number: 20030158888Abstract: The present invention relates to a method in connection with transfer of information, a system and a computer-readable medium storing computer-readable components for transfer of information. The invention is based on the idea that a user telecommunication address is associated with a temporary telecommunication address. The temporary address, designating the server, is then sent to a service handler. The service handler sends information to said temporary telecommunication address. The server knows the coupling between the temporary address and the user address, and forwards the service handler information to the user address. By employing this concept, it is not possible for a service handler to send information directly to the user telecommunication address, since the service handler does not know said user address, but must send its information to the user address via the server, which knows the coupling between the temporary telecommunication address and the user telecommunication address.Type: ApplicationFiled: December 19, 2002Publication date: August 21, 2003Inventors: Magnus Bjorklund, Petter Ericson, Marianne Lindstrom, Martin Sandstrom

Patent number: 6570104Abstract: A position-coding pattern (3) which extends across a surface and codes a plurality of positions (7a, 7b) on the surface is described. The coding in a first dimension is based on the use of a first and a second string of symbols, each containing a predetermined number of symbols and each having the characteristic that if a specific number of symbols is taken from the first string of symbols, the location of these symbols in the string of symbols is unambiguously determined. By means of displacements between these strings of symbols, a large number of positions can be coded in the first dimension. A third string of symbols of the same type is used for the coding in a second dimension.Type: GrantFiled: May 26, 2000Date of Patent: May 27, 2003Assignee: Anoto ABInventors: Petter Ericson, Ola Hugosson

Patent number: 6563951Abstract: In a method for matching two images, each consisting of a plurality of pixels and having partially overlapping contents, the degree of correspondence between the contents of the images is determined for different displacement positions representing different overlappings of the images. More specifically, a plurality of numbers are determined for each one of a plurality of said displacement positions. Each number is formed with the aid of pixel values from both images and is used to simultaneously retrieve predefined overlap assessment values for at least two of said displacement positions. The overlap assessment values retrieved are subsequently used to determine the degree of correspondence between the images for the different displacement positions. The method is carried out with the aid of a computer and can be implemented as a computer program.Type: GrantFiled: February 17, 1998Date of Patent: May 13, 2003Assignee: C Technologies ABInventors: Christer Fåhraeus, Ola Hugosson, Petter Ericson

Publication number: 20030066896Abstract: A product is provided with a coding pattern, which codes position information in the form of coordinates for a plurality of points on the product with the aid of a plurality of marks belonging to each point. The marks have a first parameter which varies for coding of the position information. The marks additionally have a second parameter which varies for coding of further information in the coding pattern. A method and a device for coding of the coding pattern and a method and a device for decoding of the coding pattern are also described.Type: ApplicationFiled: September 13, 2002Publication date: April 10, 2003Inventors: Mats Peter Pettersson, Petter Ericson

Publication number: 20030061188Abstract: An information management system is intended for management of digitally represented information which is associated with absolute positions on an imaginary surface (200). The imaginary surface (200) contains at least two regions (201-208), each of which is dedicated to predetermined management of the digitally represented information. In the system the management of the digitally represented information is carried out on the basis of the region affiliation of the absolute positions associated with the information. The system is suitably based on use of a position-coding pattern which defines the imaginary surface (200) and which in parts is applicable on different bases. The system makes possible both digital recording of information and control of how the information thus recorded is to be managed.Type: ApplicationFiled: December 22, 2000Publication date: March 27, 2003Inventors: Linus Wiebe, Christer Fahraeus, Petter Ericson

Publication number: 20030046256Abstract: A system for information management comprises a look-up unit (4), in which are stored particulars about a plurality of regions (5′), each of which represents an area on at least one imaginary surface (5) and is allocated an address. A user unit (2) records electronically information which comprises one or more positions on the imaginary surface (5) and sends all or parts of the recorded information to the look-up unit (4). When the look-up unit (4) receives the recorded information, it identifies, based on the position content of the recorded information, a region (5′) on the imaginary surface (5) and sends the address which is allocated to the identified region to the user unit (2).Type: ApplicationFiled: April 20, 2001Publication date: March 6, 2003Inventors: Ola Hugosson, Stefan Burstrom, Petter Ericson, Roger Astrom, Jan Andersson

Publication number: 20020166895Abstract: An arrangement for handling charge card purchases has a digital pen (1; 1′) which is arranged to record the signature of a charge card purchaser in digital form when the purchaser writes the signature on a physical charge card receipt (2; 40) using a pen point (17) arranged on the digital pen. The arrangement also has a signal-processing means (16; 33) which is arranged to produce a digital charge card receipt, which corresponds to the physical charge card receipt, by storing the digital signature together with digital purchase information relating to the charge card purchase to which said physical charge card receipt relates. A charge card receipt and a method of handling charge card purchases are also disclosed.Type: ApplicationFiled: December 22, 2000Publication date: November 14, 2002Inventors: Linus Wiebe, Petter Ericson, Christer Fahraeus
