Patent number: 10413368Abstract: The present disclosure relates to an arrangement (21, 71) for minimal invasive intervention, the arrangement (21, 71) comprising a rotation body (23, 73), a retaining device (25, 75) and at least one position sensor (27, 77, 79). The rotation body is adapted to receive a medical instrument (3, 5, 7, 9, 33), or the rotation body forms a part of a medical instrument (83). The medical instrument comprises a shaft (31, 81). At least a portion of a surface of the rotation body comprises a pattern (35, 87, 91). The retaining device is adapted to at least partly surround the rotation body, such that the rotation body is retained by the retaining device in a manner allowing rotational movement of the rotation body in relation to the retaining device. The at least one position sensor is adapted for determining a position in at least two coordinates of the pattern of the rotation body. The at least one position sensor is located at, in or on the retaining device.Type: GrantFiled: August 18, 2014Date of Patent: September 17, 2019Assignee: G-coder Systems ABInventors: Jonas Nilsagard, Olle Takman

Patent number: 8391561Abstract: The present invention relates to a tension monitoring system comprising: —at least one camera for acquiring at least one image of at least one pattern located on an object of interest, wherein the pattern comprises a plurality of points and where each point is arranged on the object in such as way as to follow the movement of the object; —a computational device; wherein the computational device is arranged to analyze the acquired image for detecting the position of each pattern point using an image analysis algorithm arranged to determine the geometrical center of a point using a contrast detection method, determining the distance between at least two pattern portions, and calculating the tension induced in the object using a reference value of distance between the two pattern portions when the object is mechanically relaxed.Type: GrantFiled: July 3, 2008Date of Patent: March 5, 2013Assignee: G-coder Systems ABInventors: Olle Takman, Jonas Nilsagård

Patent number: 7957931Abstract: An absolute position detection device, system and method using a pattern comprising two types of position data: location of the pattern relative an object and position of the pattern relative a sensing device, e.g. a camera. The device comprise the sensing device acquiring images of the pattern located on the object and a computational unit analysing the images for determining absolute position of the object relative the sensing device. The present invention is realized in a number of applications, such as forming part of a torque sensor, a theodolite, an articulating arm, or an angular detector.Type: GrantFiled: October 6, 2006Date of Patent: June 7, 2011Assignee: GCoder Systems ABInventors: Jonas Nilsagard, Olle Takman, Manne Stenberg

Patent number: 4828170Abstract: The invention relates to heating apparatus for heating confined spaces, and particularly for heating passenger compartments in automotive vehicles and the like. The heating apparatus comprises a combustion device having means for supplying and mixing fuel and combustion air, and an outlet for combustion gases, and further comprises a heat exchanger which is connected to the outlet of the combustion device and which is intended for heat exchange between the combustion gases and a heating medium delivered to the space to be heated. According to the invention the combustion device incorporates a catalytic reactor for catalytic combustion of at least part of the fuel-air mixture, and a thermal reactor which is located between the catalytic reactor and the combustion gas outlet and which is intended for final combustion of the fuel-air mixture at least partially combusted in the catalytic reactor.Type: GrantFiled: May 11, 1987Date of Patent: May 9, 1989Assignee: AB VolvoInventor: Olle Takman
