  • Publication number: 20200314651
    Abstract: 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.

  • Patent number: 8286683
    Abstract: Device for automatically separating the tire and the rim in a vehicle wheel. The feed-in device feeds in vehicle wheels and a press-in device is located in an inactive position at a distance from the rim edge and is shifted to an active position. Press-in members are adjusted in the direction of the rim in order to press in the rim edge, whereafter the rim can be pressed out. The press-in device with a number of press-in elements forms a unit, which is movably suspended from a frame in which the wheel is placed in position to separate the tire and the rim. Feed-out devices feed out the separated rims to a first collection point and the separated tires to a second collection point.
