Publication number: 20080075333Abstract: A payment product has a writing area (6c) which is intended for a user's signature. In the writing area there is a first position-coding pattern (5) which makes possible digital recording of the signature. The first position-coding pattern is a subset of a larger second position-coding pattern. The payment product is used in a payment system which is based on electronic payment information, which has been recorded by means of the position-coding pattern, being sent to a server unit, which utilizes the position-coding pattern to check that the payment information is valid.Type: ApplicationFiled: October 8, 2004Publication date: March 27, 2008Applicant: ANOTO AB, c/o C. Technologies AB,Inventors: Petter Ericson, Christer Fahraeus, Linus Wiebe, Kristofer Skantze

Patent number: 6906699Abstract: An input unit has a mouse function and at least one inputting function. The input unit comprises image-recording means (8) which record images. These images are used for providing both the mouse function and the inputting function. The images are processed in the input unit or in some other unit.Type: GrantFiled: October 19, 2000Date of Patent: June 14, 2005Assignee: C Technologies ABInventors: Christer Fåhraeus, Ola Hugosson, Petter Ericson

Patent number: 6715686Abstract: A device for recording information has at least one light-sensitive sensor (8) with a two-dimensional sensor surface. The device is adjustable between a first mode and a second mode. In the first mode, the device is adapted to essentially abut against and be passed over a surface for imaging the same by means of a plurality of images. In the second mode, the device is adapted to image an object located at a distance.Type: GrantFiled: March 5, 2001Date of Patent: April 6, 2004Assignee: C Technologies ABInventor: Christer Fahraeus

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

Patent number: 6529645Abstract: In a method for recording a selected sequence of characters with the aid of a pen, the latter is passed over the sequence of characters and a plurality of images, whose contents partially overlap, are recorded simultaneously with the aid of a light-sensitive sensor (8) with a two-dimensional sensor surface. The recorded images are put together, horizontally as well as vertically, into an image. Subsequently, the characters in the composite image are identified and stored in the pen with the aid of a predetermined character code formal. The putting-together, the character identification, and the storing are carried out with the aid of a signal processing unit (20-24). By the method and the pen compensation is obtained for different speeds of movement and different angles of rotation of the pen.Type: GrantFiled: April 29, 1999Date of Patent: March 4, 2003Assignee: C Technologies ABInventors: Christer Fåhraeus, Jan Nilsson, Patrik Söderlund

Patent number: 6509893Abstract: A reading pen for reading text has an elongate casing with a reading opening (3) formed in one end thereof, a printed circuit board (5) which is arranged inside the casing, light-emitting diodes (7a, 7b)) arranged inside the reading opening and adapted to illuminate the text that is to be read, and a light-sensitive sensor (9) arranged inside the reading opening and adapted to read the illuminated text. The printed circuit board (5) has an end portion at said one end of the casing. The end portion essentially corresponds to the form of the casing. The light-emitting diodes (7a, 7b) and the light-sensitive sensor (9) are arranged on said end portion.Type: GrantFiled: June 27, 2000Date of Patent: January 21, 2003Assignee: C Technologies ABInventors: Noroz Nader Akhlagi, Fredrik Lonn, Peter Wittrup
