摘要： Release mechanism (12) for an energy harvesting arrangement (10) for an electronic locking system (78), the release mechanism (12) comprising a drive device (18); a harvesting elastic element (30); at least one magnet (36); an input device (38); and an engaging profile (52); wherein the input device (38) is arranged to engage the drive device (18) by means of a magnetic force such that the drive device (18) can be displaced from a starting position (32) by movement of the input device (38) along a harvesting path (58); and wherein the engaging profile (52) is arranged to engage the drive device (18) at an engaging position (60) of the drive device (18), such that further movement of the input device (38) along the harvesting path (58) causes a relative inclination between a drive device surface (26) and a input device surface (42). An energy harvesting arrangement (10) and an electronic locking system (78) are also provided.

摘要： It is provided it is provided a keypad comprising: a voltage bus configured to distribute power in the keypad; and a plurality of keys: a plurality of row key connections; and a plurality of column key connections: A wake-up signal causes a microcontroller to transition from a low-power state to an active state such that the microcontroller can detect which one of the plurality of keys was actuated. Each key is connected to a single row key connection and a single column key connection. Each row key connection and/or each column key connection is provided with a respective port circuit that is configured to connect the key connection with keys of the keypad when the wake-up signal is activated. Each port circuit comprises a respective port switch that is turned off in the low-power state to disconnect the column key connections/row key connections from the keys of the keypad.

摘要： 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.

摘要： A brake device (12a, 12b) comprising a hard magnet (20); a soft magnet (22) configured to switch polarity between a first polarity and a second polarity when being subjected to a magnetic field and configured to maintain the polarity when the magnetic field is removed; an electric coil (24) located around the soft magnet; an electric control system (16) configured to apply a current pulse to the electric coil to generate the magnetic field for changing the polarization of the soft magnet; and a brake element (18) comprising a magnetic target section (28), the brake element being arranged to move to a released position (40) when the soft magnet adopts the first polarity, and arranged to move to a braking position (64) due to a magnetic field generated by the hard magnet and the soft magnet in combination and acting on the magnetic target section when the soft magnet adopts the second polarity.

摘要： 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.
