A bumping preventing arrangement () for a lock device (), the bumping preventing arrangement () comprising transfer member () having a magnet (), the transfer member () being movable along an actuation axis () between a locked position () and an unlocked position (); a plurality of electric conductors (), each electric conductor () enclosing the actuation axis (); and a plurality of switches (), each switch () being associated with a respective electric conductor (), and being arranged to selectively close an electric circuit comprising the associated electric conductor () such that eddy currents are induced in the electric conductors () when the magnet () moves along the actuation axis () from the locked position () towards the unlocked position (). A lock device () and a method of controlling a lock device () are also provided.

Bumping preventing arrangement for lock device, lock device and method

Release mechanism () for an energy harvesting arrangement () for an electronic locking system (), the release mechanism () comprising a drive device (); a harvesting elastic element (); at least one magnet (); an input device (); and an engaging profile (); wherein the input device () is arranged to engage the drive device () by means of a magnetic force such that the drive device () can be displaced from a starting position () by movement of the input device () along a harvesting path (); and wherein the engaging profile () is arranged to engage the drive device () at an engaging position () of the drive device (), such that further movement of the input device () along the harvesting path () causes a relative inclination between a drive device surface () and a input device surface (). An energy harvesting arrangement () and an electronic locking system () are also provided.

Release mechanism, energy harvesting arrangement and electronic locking system

Release mechanism for an electronic locking system, wherein the release mechanism is configured such that an input member and an output member are locked against relative rotation and can rotate together within a locking ring opening when a locking member is located in an input member recess and in an output member recess, and such that the output member is released to rotate relative to the input member when the locking member is located in the output member recess and in a locking ring recess. A freewheel mechanism and assemblies for an electronic locking system are also provided.

Mechanisms, assemblies and electronic locking system

Release mechanism () for an electronic locking system (), wherein the release mechanism () is configured such that an input member () and an output member () are locked against relative rotation and can rotate together within a locking ring opening () when a locking member () is located in an input member recess () and in an output member recess (), and such that the output member () is released to rotate relative to the input member () when the locking member () is located in the output member recess () and in a locking ring recess (). A freewheel mechanism () and assemblies () for an electronic locking system () are also provided.

It is presented a power converter for transferring electric power provided on an input terminal to an energy storage element. The power converter comprises: an inductor; a switch connected to selectively control a connection between the inductor and the input terminal; and a comparator, wherein an output of the comparator controls the switch, a first input of the comparator is supplied with a voltage being proportional to a voltage of the input terminal, and a second input of the comparator is supplied with a voltage being proportional to a current from the input terminal; wherein the energy storage element is connected to a point between the inductor and the switch.
