摘要： It is provided a method for determining when a portable key device is located on a front side or on a back side in relation to a barrier secured by an electronic lock. The method is performed in a location determiner and comprises the steps of: obtaining a channel impulse response, CIR, based on an impulse signal transmitted from the portable key device, the CIR being based on a plurality of samples of the impulse signal as received by an antenna being fixedly mounted in relation to the electronic lock; and determining, based on the CIR, whether the portable key device is located on the front side or on the back side.

摘要： This disclosure describes techniques for updating firmware of a secure element. The techniques include operations comprising: receiving, by a gateway device, from a remote source, a firmware file; receiving, by a processing element implemented on the gateway device, ephemeral session specific key material for a first secure element implemented on the gateway device; dividing the firmware file into a plurality of data chunks; applying, by the processing element, the ephemeral session specific key material to a first data chunk of the plurality of data chunks to generate a first data packet; and sending, by the processing element, the first data packet to the first secure element.

摘要： The present disclosure relates to a reader, such as a reader for a physical access control system. The reader can include first and second antennas, each designed or configured for receiving ultra-wide band (UWB) signals. The reader can also include a mounting plane configured for mounting the reader to a surface. An axis aligning the first and second antennas can be arranged substantially perpendicular relative the mounting plane. A material can be provided between the first and second antennas The material can have a thickness that defines a distance between the first and second antennas of less than a half wavelength of the UWB signal through air (λA/2), the material configured to slow down electromagnetic waves passing therethrough such that the thickness of the material provides an effective separation distance of the first and second antennas of at least a half wavelength of the UWB signal through air (λA/2).

摘要： Systems and techniques for a physical access control systems with localization-based intent detection are described herein. In an example, an access control system may regulate access to an asset. The access control system is adapted to establish a first connection with a key-device. The access control system may be further adapted to receive a credential for a user over the first connection. The access control system may be further adapted to establish a second connection with the key-device. The access control system may be further adapted to determine an intent of the user to access the asset. The access control system may use location data derived from the second connection to determine the intent of the user. The access control system may be further adapted to provide the credential to an access controller, based on identifying an intent of the user to access the asset.

摘要： According to a first aspect, it is presented a method for requesting access to a physical space controlled by an electronic lock. The method is performed in a user device and comprises the steps of: reading a tag using a near field radio protocol, yielding a tag identifier, the tag being distinct from the electronic lock; finding, based on the tag identifier, a lock identifier associated with the tag identifier, wherein the tag identifier is distinct from the lock identifier; and sending an access request message to the electronic lock having the lock identifier.

摘要： Systems and techniques for improving ink jet ink durability and adhesion to a substrate. The techniques may include applying a varnish to the surface of the substrate, curing, in an initial curing step, the varnish with an ultraviolet (UV) lamp, and applying a pigmented ink to at least a portion of the substrate. The initial curing step may comprise pinning the varnish with the UV lamp in a low-power state. The techniques may additionally or alternatively include applying a layer of pigmented ink and varnish at substantially the same time, allowing the pigmented ink and varnish to at least partially mix, then pinning or curing the ink/varnish combination.
