  • Patent number: 9443362
    Abstract: Credential data representing users seeking access to a well-defined space are registered in a reader unit associated with an access-control-related building component. A linked address associates the credential data with a first credential data receiver (EAC1) and/or at least one second credential data receiver (EAC2). The address is stored in a memory at the reader unit or on a portable carrier holding the credential data. If the address identifies the first credential data receiver (EAC1), the reader unit forwards the registered credential data to this unit (EAC1). If the address (A) identifies a particular second credential data receiver (EAC2), the reader unit instead forwards the registered credential data (CD) to this unit (EAC2). When receiving the credential data, the units (EAC1; EAC2) effect at least one decision concerning the well-defined space independently of one another.

  • Patent number: 9397383
    Abstract: The present invention relates to a system for mast vibration compensation implemented in a communication system including a first node and a second node. The first node comprises a first adaptive antenna mounted in a mast; a receiver connected to said antenna; and a spatial and temporary processing system. The first adaptive antenna is controlled by a first correction signal generated in the spatial and temporary processing system. The correction signal is based on a parameter that indicates that a radio link alignment with a second node is degrading due to mechanical vibrations in the mast. The invention also relates to a method for mast vibration compensation.
