The invention concerns a rotor blade of a wind power installation, comprising a rotor blade root (4) for attachment of the rotor blade to a rotor hub and a rotor blade tip arranged at a side remote from the rotor blade root, as well as a wind power installation having such rotor blades. In that arrangement a relative profile thickness which is defined as the ratio of profile thickness to profile depth has a local maximum in a central region between rotor blade root and rotor blade tip.

A guide system for guiding a movably mounted furniture part, in particular a folding or folding-sliding door, includes a longitudinal guide rail, at least one guide device via which the furniture part is movable in a longitudinal direction along the longitudinal guide rail, and at least one support on which the furniture part is mounted in an articulated manner. The at least one support is movable in a direction extending transversely to the longitudinal direction of the longitudinal guide rail, and the at least one support has a receiver for receiving the guide device and the support is movable in the mounted position into a transfer position in which the receiver is arranged adjacent to the longitudinal guide rail. A compensation device compensates for a height difference between the receiving device and the longitudinal guide rail is provided.

A connector terminal preparation method includes the step of preparing a metal socket having a base and a cylindrical body extended from the base and then making a through hole on the base in communication with the inside of the cylindrical body and then electroplating a metal coating layer on the inner and outer surfaces of the base and cylindrical body of the metal socket, and the step of employing a mechanical processing process to deform the base of the metal socket and to have the through hole of the metal socket be fully enclosed.

Methods and systems are disclosed for radio positioning of a vehicle using a virtual positioning reference established by logging a known position of the vehicle together with a local time that a first instance of a predictably repeated code word is received from an opportunistic terrestrial radio transmitter. During movement of the vehicle to a second, unknown position, a local clock is used to determine the time difference between when the virtual positioning reference is predicted to receive a second instance of the code word and when the vehicle actually receives the second instance of the code word, thereby providing positioning information when traditional navigation signals such as GPS are not available. The radio positioning information is then used to initiate an action such as recording the location information for future retrieval by a user, and / or controlling the movements of an autonomous vehicle.

The present disclosure relates to a piston pump assembly comprising a piston with a variable stroke and to a hydraulic braking system comprising the same. The piston pump assembly comprises at least: a rotatable drive shaft defining an axis of rotation of the rotatable drive shaft; a cam disposed on the drive shaft; and the piston biased toward the cam and configured to reciprocate along a piston axis for displacing a hydraulic fluid. The cam is movable relative to the piston axis and is selectively placed in one of a first position at a first distance from the piston axis and a second position at a second distance from the piston axis; and wherein the cam comprises at least two portions each of which has, at a given position of the cam relative to the piston axis, a different non-circular cross section in a plane perpendicular to the axis of rotation and / or a different eccentricity with respect to the axis of rotation, the at least two portions of the cam comprising at least a first cam portion having a first non-circular cross section and / or a first eccentricity, and a second cam portion having a second non-circular cross section and / or a second eccentricity.
