Abstract: Embodiments provide techniques for providing return-link routing in a hybrid communications network that includes a number of different networks having different characteristics. User terminal routing systems (UTRSs) provide interfaces between local user networks and the multiple communications networks of the hybrid network. Each UTRS can include a routing table having stored mappings that are populated according to forward-link communications (implicitly or explicitly), each associating a respective one of a plurality of routing table entries with one of the communications networks. When a UTRS receives return-link data from its respective local user network, the received data indicates a destination node. The UTRS can determine which of the stored mappings corresponds to the destination node and can route the received return-link data over a selected one of the communications networks in accordance with the identified one of the mappings.

Abstract: The invention describes a femur marrow nail for insertion between the condylii of a knee joint having an anchoring (4) in the region of the nail tip (3), having a curvature (6) extending in the sagittal plane (5) and having a straight end piece (7) which has fastening bores (12, 13) with axes B, C for its fastening. At least two fastening bores (12, 13) with axes B and C cross the longitudinal axis X of the end piece (7) at a spacing X2, X3 less than 70 millimeters from the end (8) of the end piece (7), and with their axes B and C penetrating a plane (10) which includes the end (8) and is perpendicular to the longitudinal axis X at a distance r from the X axis in a region of 10 mm≦r≦116 mm in order to grip hard bone zones with fastening screws (15, 16) in the region of the condylii.

Abstract: A bone plate for the splinting of a fracture at a bone with a plurality of bone screws. An elastic cushion is provided between the bone screws and the bone plate in the direction towards the fracture. The screw head penetrates through the bone plate completely and lies on the bone with a contact surface under a bias force. A ring body is molded onto the elastic cushion and can be mounted at the lower side of the bone plate. The ring body and the contact surface of the screw head both project beyond the lower side of the bone plate.
