Abstract: A device for the positioning of an electronic unit on a front-end section of a drill string of a ground drilling device, wherein the electronic unit is designed to determine at least one of the following pieces of information: location, height, position and direction, and wherein the device has a seat for the electronic unit and a bearing surface adapted to the outer contour of the front-end section.

Abstract: Antenna of a shape that allows for its integration in a laptop or tablet computer, which antenna has dual band or multi band functionality, and comprises: an elongate carrier structure of electrically insulating material, and an electric circuitry provided on the carrier structure, which comprises the following electrically conductive elements: a ground plane, two or more antenna elements spaced apart from each other, one or more filter elements which are positioned between a pair of adjacent antenna elements, wherein the antenna elements and the filter elements are electrically connected to the ground plane, and wherein the carrier structure contains a feed connector system that allows for an electrical connection between an external feed line and the antenna elements, and wherein the parts of the carrier structure on which the antenna elements are provided, has a relative dielectric constant of at least 2.0, and is of a substantially solid design, which preferably has a minimum cross-sectional area of 0.

Abstract: A long-shaft tool includes a shaft extending along a longitudinal axis and having a handle at a first end of the shaft and a second end opposite the first end with a holder for a manipulator wherein the holder has a protruding latch pin provided for engagement with a recess of a manipulator, which can be moved from the protruding position into a retracted position. The holder has a coupling half for coupling with a coupling half of a manipulator which is rotatable relative to a base body of the shaft.
