Abstract: A rotor for a wind, to a wind turbine and to a method for increasing the yield of a rotor of a wind turbine. In particular, a rotor for a wind turbine, comprising at least one rotor blade, having a rotor blade trailing edge and rotor blade leading edge extending between the rotor blade root and the rotor blade tip over a rotor blade length, a profile depth established between the rotor blade leading edge and the rotor blade trailing edge, and an adjustable pitch angle, wherein the rotor blade has at least one profile element which is arranged on the rotor blade trailing edge or in the region adjacent to the rotor blade trailing edge for increasing the profile depth by an enlargement value, characterized by a control unit for determining a pitch angle to be set, which is configured to determine the pitch angle to be set depending on the enlargement value.

Abstract: A method for operating a navigation system is disclosed. An ordered plurality of interconnected segments providing a route from an origin to a destination is obtained. A guidance message for each of the segments is formed. The step of forming the guidance message comprises determining whether to reference a previous segment and adding a reference to a current segment.

Abstract: A method for collecting geographic data for use with a navigation system is disclosed. A pedestrian segment associated with a path is identified. A text description of the pedestrian segment is collected. The text description includes one of a predetermined number of phrases and a name of at least one feature visible from a location of the pedestrian segment. Data representing the pedestrian segment is stored in the geographic database.

Abstract: A method for collecting geographic data for use with a navigation system is disclosed. A virtual pedestrian segment providing a path through an unorganized geographic area is identified. The unorganized geographic area lacks underlying organization into roads and paths. Data indicating a location of the virtual pedestrian segment is collected. Data representing the virtual pedestrian segment is stored in the geographic database, and the geographic database is provided for use with navigation related features.
