    Abstract: Transformation method of hybrid transportation vehicle for ground and air includes the following transformation and reciprocal steps: Tilting the compensation cover (7) on. Expansion of both whole wings (1) from the transportation vehicle longitudinal position around two vertical axes (2) into the flying position. Expansion of rear parts of wings (1) from the top front parts of wings (1) into the spread flying position by tilting the rear of each wing (1) around a horizontal axis (3). The take-off and landing tilting of wings (1) by an angle of attack alpha=0 to 40° of the wings onset. Front wheels track (5) is reduced by axially shifting the front wheels (5) towards the fuselage. Furthermore, a corresponding hybrid transportation vehicle for ground and air is described which contains reciprocal transformation mechanisms for transformation from a sterling double or four-track automobile into a sterling aircraft for take-off and landing on the ground or water, and vice versa.

  • Patent number: 8320237
    Abstract: A method for minimizing bandwidth allocation for alternative routes within a network provides a management system for managing routes of services, provides a plurality of guaranteed bandwidth (GWB) services, assigns to each GBW-service a traffic class (TC), and calculates for each GBW-service of a protected TC an active route and an alternative route. The active route is a planned route in case of absence of a respective network failure and the alternative route is the route which guarantees that, in case of a network failure with respect to the active route, the GBW-service is protected. Further, a first optimized protection mode is provided to be assigned to all the GBW-services belonging to a given protected TC. The first optimized protection mode has a first optimization step including reserving bandwidth for each GBW-service only once for each network resource employed by the active and/or the alternative route of each GBW-service.
