Method and arrangement for determining position of vehicles relative each other

Abstract: A relative positioning system, an arrangement, and a method. A method for determining a position of a second vehicle relative to a first vehicle. At least an image of a field of view wherein the second vehicle is positioned within the field of view is recorded using an optical device mounted on the first. Image data is processed in a processor to determine a position of the second vehicle relative the first vehicle measuring at least one marker arranged on the second vehicle in the image.

Simulation device and simulation method

Abstract: A simulation device for generating an answer to a question inputted thereto. A communication unit is configured to input a selected question associated with a first criterion and a second criterion. A generating unit is configured to generate a copy of a continuously updated environment model. A generating unit is configured to generate a simulation scenario, depending upon the first criterion. A modifying unit is configured to modify the generated simulation scenario. An applying unit is configured to apply the modified generated simulation scenario to the generated copy of the continuously updated environment model. A simulating unit is configured to perform a simulation process in accordance with the second criterion. An answering unit is configured to answer information, depending upon a result of the simulation process.

A tool, a machine tool, and a method of cutting

Abstract: The invention refers to a tool (1), a machine tool, and a method for cutting machining of a workpiece. The tool includes a mounting portion (5) for mounting of the tool in the machine tool, a tool shaft (7), which has a first inner end (7'), connected to the mounting portion (5), a longitudinal centre axis (a), which extends through the mounting portion and the tool shaft, and a main cutting edge (9) on the tool shaft. The main cutting edge (9) has an extension in an axial direction along an imaginary envelope surface, which is concentric to the centre axis (a) and located radially outside an outer periphery surface of the tool shaft (7). The main cutting edge (9) is arranged to permit cutting engagement with said workpiece when the tool is rotated around the longitudinal centre axis.

A range estimation device

Abstract: The invention relates to a range estimation device for use in an aerial platform comprising at least one passive sensor, a trajectory determination unit and a control system. The range estimation device comprises a control unit arranged to indicate to the control system to perform own-ship manoeuvring of said aerial platform such that the characteristics of passive sensor measurements from said at least one passive sensor enable a range estimation to a target to be determined. The range estimation device is characterized by the control unit being arranged to determine the characteristics of the own-ship manoeuvring based on the range uncertainty estimations to the target. The invention also relates to a method and a computer program product for use in range estimation device.
