Publication number: 20200261262Abstract: A cooling system (10) for cooling at least one extremity, such as a finger or toe, or body part of a human is provided. The cooling system (10) comprises at least one malleable thermal conductive viscoelastic material (11), adapted to be formed into a homogenous body around and fully covering the at least one extremity or body part, thereby providing for a complete and continuous direct contact between the malleable thermal conductive viscoelastic material and the at least one extremity or body part. Moreover, the cooling system (10) comprises a cooling circuit (12) for providing cooling at least partly around said homogenous body of malleable thermal conductive viscoelastic material (11).Type: ApplicationFiled: October 31, 2018Publication date: August 20, 2020Applicant: BrainCool ABInventors: Martin WALEIJ, Christian STRAND, Ola STRÖMBERG, Jonas BLANKING

Patent number: 8411071Abstract: An electronic pen has a casing and a tip to be put on a surface. The pen includes a positioning module for detecting the position of the tip on the surface, and an audio module configured to output signals responsive to the detected position of the tip on the surface. The modules form a unitary component mounting unit contained within the casing. The pen also has: an audio box with a speaker, means for connecting the modules, and a locking arrangement for locking the casing.Type: GrantFiled: February 21, 2007Date of Patent: April 2, 2013Assignee: Anoto ABInventors: Fabian Henning, Ola Strömberg

Patent number: 7868878Abstract: A modular unit is designed for an electronic pen. The modular unit comprises a carrier (70) with a receiver for a writing implement, a printed circuit board (72), a two-dimensional radiation sensor (78) mounted on the printed circuit board, and an imaging unit (82) which defines an image plane. The carrier (70), the printed circuit board (72), and the imaging unit (82) are joined together with the imaging unit (82) facing the radiation sensor (78) to locate the image plane at the radiation sensor (78). The modular unit may comprise an analysis system dedicated to a particular optical analysis application, such as position determination based on images of a position-coding pattern. A radiation source, such as an LED or a laser diode, may be arranged on the printed circuit board or mounted in a holder on the imaging unit. The imaging unit (82) may be implemented as a boresight unit for controlling the spatial origin of radiation transmitted towards the radiation sensor (78).Type: GrantFiled: December 15, 2004Date of Patent: January 11, 2011Assignee: Anoto ABInventors: Thomas Craven-Bartle, Ola Wassvik, Peter Gredinger, Ola Strömberg

Patent number: 7382361Abstract: An electronic pen has a force sensor whose electrical resistance varies in accordance with the amount of force applied to the pen stem of the pen. The force sensor is a modular unit with an electrode and a closure, which are mutually arranged in an essentially electrically insulated initial position. The closure, which conveniently is cantilevered on the electrode, is adapted to receive axial forces from the pen stem and thereby to be urged to an activated position in electrical contact with the electrode. The closure is also arranged, on relaxation of the axial forces, to automatically spring from the activated position back to the initial position.Type: GrantFiled: February 12, 2003Date of Patent: June 3, 2008Assignee: Anoto ABInventors: Stefan Burström, Mattias Bryborn, Peter Gredinger, Ola Strömberg, Magnus Horrdin

Patent number: 7180509Abstract: An electronic pen comprises a writing means (7) which extends into the interior of the pen, a guiding element (9) for the writing means (7), a sensor (15a) for recording images and an image processor (30) for calculating positions of the pen based on said images. The sensor (15a) is part of an imaging detector unit (15). The guiding element (9) and the detector unit (15) are arranged in a common mounting part (5) which is fixedly mounted in the interior of the pen. In such a pen, it is possible to minimize the tolerance chain between the components that convert a pen stroke on a base into a sequence of positions. This enables serial production of the pen with a small number of rejects.Type: GrantFiled: June 26, 2002Date of Patent: February 20, 2007Assignee: Anoto ABInventors: Björn Fermgård, Ola Strömberg
