  • Publication number: 20200217920
    Abstract: The disclosed subject matter relates to a method and a system for determining a position of a movable agent device in a reflective environment of which a geometric model is known and in which at least one anchor device has a predetermined position, comprising: transmitting a first and a second ultra-wideband pulse signal via a first and a second uni-directional antenna of the anchor device, respectively, and receiving respective received signals via an omni-directional antenna of the agent device; defining a set of candidate positions within said geometric model, and, for each candidate position, calculating a set of multipath components as a function of the geometric model, directivities of the uni-directional antennas and the position of the anchor device; determining a deviation measure between the calculated multipath components and said received signals; and obtaining the position of the agent device as the candidate position with the minimum deviation measure.

  • Publication number: 20070293380
    Abstract: In order in fast clamping of a tool to a machine tool to provide a small amount of play between the tool (2) and the fastening device (1) in a rest position and/or in operation, there is proposed a fastening device having at least one projection of a closure means which can be actuated without the use of a tool and with which the fastening device, wherein in the closed position the projection (410) of the fastening device engages over an associated closure surface (220) of the tool and the tool body is axially secured and held non-rotationally.

  • Patent number: 7192338
    Abstract: A tool for co-operating with a fixing device wherein the tool comprises a tool body in the form of a circular disk, with a central opening and a radially inwardly facing locking surface. The fixing device comprises at least one radially outwardly facing projection of a locking element, which can be actuated manually and with which the fixing device can be releasably connected to the tool. In the locking position the at least one radially outwardly facing projection of the fixing device engages over the inwardly facing locking surface of the tool. The tool body is axially secured and held non-rotatably relative to the fixing device. The at least one radially outwardly facing projection of the fixing device and a support for the tool are arranged axially displaceably relative to each other, wherein the axial displacement travel is blockable by a centrifugal force device.

  • Publication number: 20050075059
    Abstract: The aim of the invention is to fix or detach tools (23, 38) comprising a disc-shaped tool body (21, 28), in particular cutting discs, rough-grinding discs or fan grinding discs, to or from a machine tool, in a simple manner, without involving complex and expensive resources. To achieve this, the invention provides a fixing device (1, 32), in addition to a tool that is designed to interact with the fixing device and has a disc-shaped tool body with a central opening, which together form a clamping system. According to the invention, the fixing device, which can be mounted onto a machine tool, or is attached to the machine tool in a fixed manner, comprises at least one radially outward-facing projection (5) of a lock that can be operated in the absence of a tool, said lock detachably connecting the fixing device to the tool.
