  • Patent number: 11716653
    Abstract: A transport path group for uplink transmission over a fronthaul interface. The transport path group may include (i) an address of a first source port of a radio unit (RU), (ii) an address of a first destination port of a distributed unit (DU), and (iii) an address of a second source port of the RU, an address of a second destination port of the DU, and/or a flow identifier (e.g., a virtualized local area network (VLAN)). A request for user data conveyed by the DU and received by the RU may identify the transport path group. The RU may use the fronthaul interface to convey to the DU first and second portions of the requested user data over first and second different paths from the RU to the DU. The RU may employ load balancing parameters to convey the first and second portions of the requested user data.

  • Patent number: 8132530
    Abstract: The invention refers to a milking device for milking an animal during a milking operation. A milking member (5) includes at least one teatcup (6) to be attached to a teat of the animal. A long milk conduit (10) extends from the milking member for being connected to a milking machine. A support device (15) comprises a mounting device (16) mounted to a stationary structure (2), and a support arm (17a) in parallel to an arm axis and connected to the mounting device. The milking member is freely movable along the support arm. The milking member is attached to the support arm and displaceable on the support arm. The support arm includes a primary arm element (17a?) connected to the mounting device and a secondary arm element (17a?) holding the milking member. The primary arm element is telescopically introduceable into the secondary arm element, which is displaceable on the primary arm element.
