    摘要： It is provided an electronic lock for controlling access to a restricted physical space. The electronic lock comprises: a first credential interface for accepting a credential from a user for evaluating whether access for the user should be granted; and a second credential interface for accepting a credential from a user for evaluating whether access for the user should be granted. The first credential interface is configured to be activated when the user causes an interaction with the first credential interface, without activating any other credential interfaces. The second credential interface is configured to be activated when a user causes an interaction with the second credential interface, without activating any other credential interfaces.

    摘要： It is provided a method for enabling access, using a temporary passcode (25. 25a-f), to a physical space (16) secured by an electronic lock (12). The method is performed in a passcode provider (1). The method comprises: synchronising (40) with the electronic lock (12) to align times for temporary passcode generation: receiving (42) a signal to provide a temporary passcode for unlocking the electronic lock: determining (44) a temporary passcode, the temporary passcode being valid only until an end time at the electronic lock (12); and providing (46) the temporary passcode for forwarding to a temporary passcode recipient.

    摘要： It is provided a method for configuring a target device. The method comprises the steps of: transmitting a configuration request message to the target device, the configuration request message comprising a configuration request and a request signature, wherein the request signature is based on the configuration request; receiving a configuration response message from the target device, the configuration response message comprising a configuration response and a response signature, wherein the response signature is based on the configuration response and the request signature; verifying the response signature to determine whether the configuration response message is valid, based on the configuration response, the request signature and a public key for the target device; and transmitting a configuration commit message to the target device only when the configuration response message is valid, the configuration commit message comprising a configuration commit indicator and a commit signature.

    摘要： Lock device for an electronic locking system, the lock device comprising an input member arranged to rotate about an input rotational axis; an output member arranged to rotate about an output rotational axis; an energy harvesting arrangement configured to generate electric energy from rotation of the input member in a first direction about the input rotational axis; and a selective transfer device movable between a locking state, in which the output member cannot be rotated about the output rotational axis by means of rotation of the input member about the input rotational axis, and an unlocking state, in which the output member can be rotated about the output rotational axis by means of rotation of the input member in the first direction about the input rotational axis; wherein the transfer device is powered by the energy harvesting arrangement. An electronic locking system and a method are also provided.

    摘要： Systems and techniques for preserving and improving ink jet nozzle health and printing reliability are disclosed herein. The method may include monitoring whether a triggering event has occurred. In response to detecting the triggering event has occurred, pumping at least a portion of ink contained in a header tank in a direction toward an ink cartridge through a tube connecting the header tank to the ink cartridge. The header tank connected to a print head included as a part of a scan head. The method may further include circulating the ink through the tube back into the header tank, and agitating the scan head by moving the scan head along an x-y gantry. Additional methods may include reverse purging, ejecting a portion of ink through nozzles on the print head while simultaneously wiping a nozzle plate included on the print head, and randomizing print head location when printing.

    摘要： It is provided a method for determining whether a portable key device is located inside or outside a metal door. The method is performed by a credential communication device and comprises the steps of: obtaining a first time-of-flight, ToF, measurement between a first antenna and the portable key device, wherein the first antenna is located on the outside of the metal door; obtaining a second ToF measurement between a second antenna and the portable key device, wherein the second antenna is located on the inside of the metal door; and determining the portable key device to be located on the outside of the metal door when the first ToF measurement is less than the second ToF measurement by an amount which is greater than a threshold value.

    摘要： A method of integrating a logical access control system with a physical access control system is disclosed. A soft token is received at a hard-ware accessory from a client device of a user. The soft token includes a payload. The payload includes information about the user that is stored in a user profile of the logical access control system. Based on a verifying of the soft token using a certificate extracted from a trust store of the hardware accessory, the information about the user that is included in the payload is parsed. Based on the information about the user satisfying one or more access criteria of a reader associated with a physical access control system, the reader is triggered. The triggering includes emulating a transaction associated with the physical access control system.
