Abstract: This disclosure describes techniques for operating an inductive coupling reader. The techniques include operations comprising: applying an excitation frequency to a resonance circuit of the inductive coupling reader; detecting a change to a resonance frequency of the resonance circuit of the inductive coupling reader; and in response to detecting the change to the resonance frequency of the inductive coupling reader, adjusting the excitation frequency being applied to the resonance circuit.

CPC classification number: E05B63/20 , E05B63/16 , E05B47/0038
Abstract: A lock device (12) comprising a bolt (22) movable between a retracted position (24) and an extended position (90); a bolt force device (26) arranged to force the bolt (22) from the retracted position (24) towards the extended position (90); a blocking member (28) movable between a blocking position (32) and an unblocking position (96); a lock device magnet (46) movable between a passive position (48) and an active position (94) in response to a repulsive magnetic force acting on the lock device magnet (46); and a release transmission (52) arranged to mechanically transmit a movement of the lock device magnet (46) from the passive position (48) to the active position (94), to a movement of the blocking member (28) from the blocking position (32) to the unblocking position (96). A system (10) comprising a lock device (12) and a strike plate (14) is also provided.

Abstract: Methods and systems for establishing a system specific trust system are provided. The methods and systems establish a secure channel between a first device and a second device using a system specific trusted authority. The methods and systems determine, by the first device, using a first certificate associated with the second device, a first set of access rights of the second device and determine, by the second device, using a credential associated with the first device, a second set of access rights of the first device.

Abstract: Methods and systems for communicating with an access control system preserving privacy are provided. The methods and systems establish, between a first device and a second device, a privacy key pair using a group generator, the privacy key pair comprising a privacy public key and a privacy private key, and compute, by the first and second devices, ephemeral key pairs based on the privacy key pair. The methods and systems establish a shared session key based on the ephemeral key pairs and transmit, by the first device to the second device, a message comprising a certificate of the first device using the shared session key that has been established based on the ephemeral key pairs.
