  • Patent number: 11577798
    Abstract: 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.

  • Patent number: 10553378
    Abstract: 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.

  • Patent number: 10109109
    Abstract: 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).

  • Patent number: 9627153
    Abstract: An electrical switching device for medium or high voltage circuits having at least a nominal contact arrangement, wherein the nominal contact arrangement includes at least a first nominal contact including a plurality of contact fingers forming a finger cage concentric with respect to a longitudinal axis, wherein the contact fingers are separated from one another by empty slots extending up to a free end of the contact fingers. The empty slots include first and second empty slots, wherein the second empty slots are shorter than the first empty slots, and wherein the contact fingers are grouped in groups, with the contact fingers of each group being separated by second empty slots and the contact fingers of adjacent groups being separated by first empty slots.

  • Patent number: 9627155
    Abstract: 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.
