Patent number: 11549494Abstract: A method for performing maintenance on an outer surface of at least one wind turbine part, such as a tower (2), a nacelle (3) or a wind turbine blade (5), of an offshore wind turbine (1) is disclosed. An access system (10) is transported to a site of the offshore wind turbine (1), and the access system (10) is transferred to a transition platform (6) at a lower part of the offshore wind turbine (1), while operating the offshore wind turbine (1) in accordance with a normal operating mode. Normal operation of the offshore wind turbine (1) is then stopped, and maintenance is performed on an outer surface of at least one wind turbine part (2, 3, 5) of the offshore wind turbine (1), using the access system (10). When the maintenance has been completed, normal operation of the offshore wind turbine (1) is restarted in accordance with a normal operating mode. Normal operation of the offshore wind turbine (1) is only stopped while the actual maintenance takes place. Thereby the loss in power production is minimised.Type: GrantFiled: October 26, 2018Date of Patent: January 10, 2023Assignee: Vestas Wind Systems A/SInventor: Jan Christensen

Patent number: 10494193Abstract: The invention provides a high speed sorting mechanism arranged to empty or discharge a container for carrying a load, e.g. totes in a luggage handling system. The sorting mechanism as a plurality of tilting elements T1-T11 for receiving and transporting the container in a transport direction. The tilting elements T1-T11 are arranged neighbouring each other, and they are individually tiltable by controllable tilting actuators, e.g. servo motors. Hereby, the tilting elements T1-T11 can tilt around an axis parallel with the transport direction. A computerized controller serves to individually control the tilting of the tilting elements T1-T11 with a control algorithm in response to at least one position signal such that a group of at least two tilting elements T1-T11 perform a coordinated tilting motion in response to the position signal so as to tilt the container for emptying or discharging its load, upon the container passing the sorting mechanism in the transport direction.Type: GrantFiled: December 11, 2017Date of Patent: December 3, 2019Assignee: Beumer Group A/SInventors: Brian Lynge Sørensen, Jan Christensen

Patent number: 7905368Abstract: A portable water tank comprises a foldable receptacle having a bottom wall and vertical sidewalls; a frame to support the sidewalls in an upright position, the frame including upper and lower rails, and vertical posts joining the upper rail to the lower rail. The receptacle includes a drain sleeve disposed near the bottom wall and extends between corresponding portions of the upper and lower rails, and between a pair of the posts. The sleeve overlies the corresponding portion of the lower rail. Reinforcement members are attached to the corresponding portions of the lower rail and the pair of posts. A valve is operably attached to the pair of posts and the corresponding portion of the lower rail. The valve is operably associated with the drain sleeve and has an open position to allow water within the receptacle to flow through the drain sleeve, and a closed position to keep water from flowing through the drain sleeve.Type: GrantFiled: March 11, 2008Date of Patent: March 15, 2011Assignee: Eldred CorporationInventor: Jan Christensen

Patent number: 6181339Abstract: A method and system are disclosed for allowing selection of an icon most logically desired by the user in a graphic user interface when multiple icons are overlapping and the pointing device coordinates would force a given selection not desired by the user. A logical icon selector is provided that is coupled to the pointing device and provides a logic for selecting the desired icon based on proximity of the pointing device icon to the desired icon. Based on a calculation of the location of the overlapping icons to the pointing device icon, the icon having the closest proximity to the pointing device is selected.Type: GrantFiled: July 27, 1998Date of Patent: January 30, 2001Assignee: Oak Technology, Inc.Inventors: Linden A. deCarmo, Jan Christensen

Patent number: 5560310Abstract: A control unit incorporated in a stabilizing system in yachts and sailing vessels and intended automatically to control the movements of a weight which is movable transversely across the vessel, said wight being connected with an athwartships tiltable mast in such a manner, that the weight is displaced transversely across the vessel in a direction opposite to the mast tilting direction. The control unit comprises two stops arranged to stop the movements of the weight, and further comprises a shifting device which is actuated by the position of the wight so that one of the stops is given an opportunity to act, i.e. to stop the movements of the weight, when the weight is positioned to one side of the centre line of the vessel in the transverse direction thereof whereas the second stop is then not given an opportunity to stop the movements of the weight, and vice versa. Each stop is controlled by a sensing device responsive to the movements of the vessel.Type: GrantFiled: August 31, 1995Date of Patent: October 1, 1996Inventors: Jan A. Christensen, Carl O. Ohrn

Patent number: 5392727Abstract: A system for maintaining the hull of a sailing boat in a steady position substantially independent of wind pressures on the sail, comprising a pivoted mast and wires connecting the mast with a weight in the boat hull via a transmission device. Transverse pivoting movement of the mast causes lateral displacement of the weight thereby maintaining the hull in a stable condition.Type: GrantFiled: February 8, 1993Date of Patent: February 28, 1995Assignee: Sailmatic ASInventors: Jan A. Christensen, Carl O. Ohrn
