Patent number: 11577798Abstract: A locking system is used to safely immobilize electric motorcycles. The system involves a pin-based locking device that can be activated by the user via a key, remote and/or a switch located on the dashboard of the electric motorcycle. The locking device engages the pin with a component that is rotated by the transmission of the electric motorcycle. When activated, the locking device locks the transmission and prevents the motorcycle from being subjected to unwanted driving wheel rotation.Type: GrantFiled: October 6, 2021Date of Patent: February 14, 2023Assignee: Damon Motors Inc.Inventors: Derek Dorresteyn, Reto Karrer

Patent number: 10553378Abstract: An electric switching device filled with a dielectric insulating medium includes first and second arcing contact, first exhaust volume downstream of first arcing contact and second exhaust volume downstream of second arcing contact. The exhaust volumes includes several first openings in their walls, through which the insulating medium exits into third volume. The third volume is arranged around the first or second exhaust volume and is radially delimited by the wall of the exhaust volumes and by an exterior wall having second openings through which the insulating medium exits the third volume. One baffle device is provided inside third volume such that vortex flow of the insulating medium is generated when it passes the baffle device on its way towards the second openings. Turbulent flow conditions are chosen such that gravitational force allows to trap or contributes to trap particles in the baffle device.Type: GrantFiled: September 24, 2018Date of Patent: February 4, 2020Assignee: ABB Schweiz AGInventors: Francesco Pisu, Mahesh Dhotre, Xiangyang Ye, Johan Karl Filip Costyson, Reto Karrer

Patent number: 10109109Abstract: The invention relates to a method for inspecting a security document (10), the use of an augmented reality system (20) for inspecting a security document (10) as well as an augmented reality system (20). One or more first items of information of the security document (10) are captured by means of an augmented reality system (20), in particular a pair of smartglasses. The one or more first items of information are then checked by comparison with a database (40). Furthermore, one or more of the results of the check of the one or more first items of information are stored and/or one or more of the results of the check of the one or more first items of information are output by means of the augmented reality system (20).Type: GrantFiled: June 15, 2015Date of Patent: October 23, 2018Assignee: OVD KINEGRAM AGInventors: Reto Karrer Walker, Andreas Schilling

Patent number: 9627155Abstract: A contact arrangement has a longitudinal axis and includes a first contact group with a first contact and a second contact and a second contact group with a third contact and a fourth contact. The first contact interacts electrically and mechanically with the third contact, and/or the second contact interacts electrically and mechanically with the fourth contact, for closing and opening the contact arrangement. At least one mechanical coupling is provided for transmitting an actuation force to the second contact group and thereby moving the second contact group. The at least one mechanical coupling is adapted to move the third and the fourth contact in such a way that their speeds differ along at least a portion of a travel path of the third contact or along at least a portion of a travel path of the fourth contact.Type: GrantFiled: June 16, 2015Date of Patent: April 18, 2017Assignee: ABB Schweiz AGInventors: Helmut Heiermeier, Jadran Kostovic, Jakub Korbel, Reto Karrer, Sami Kotilainen, Timothy Sutherland, Brant Suhrie
