  • Patent number: 8220173
    Abstract: An articulated arm system can include an articulated measuring arm with a plurality of interconnected support arm segments. The arm segments can be moveable about a plurality of axes. A plurality of rotational angle sensors can mount on the arm and be configured to measure rotational position between the support arm segments. Additionally, a vibration detection device can attach to the arm near an end of the arm. The vibration detection device can be operatively connected to the sensors such that the sensors output a rotational position upon detection of a new vibration exceeding a threshold amplitude.

  • Publication number: 20120090185
    Abstract: A coordinate measurement device comprises an articulated arm and a laser scanner assembly. The articulated arm can have a first end, a second end, and a plurality of jointed arm segments therebetween. Each arm segment can define at least one axis of rotation, and a last axis of rotation can be defined by bearings near a distal end of the arm. The laser scanner assembly can couple to the distal end of the arm. The arm can continuously generate trigger signals that are received by the laser scanner and indicate a time at which the arm's position is measured.

  • Publication number: 20120047756
    Abstract: An articulated arm can include a plurality of articulated arm members, a probe, a receiving portion at a distal end comprising a threaded portion, and a base at a proximal end. A base plate can kinematically mount on the receiving portion and have a hole positioned such that the probe passes through the hole. The base plate can also couple to a laser and an optical sensor located on opposite sides of the hole. A nut can threadably mount to the threaded portion of the receiving portion. Further, a wave spring can mount on the receiving portion between the nut and the base plate. Thus, movement of the nut along the receiving portion can cause the wave spring to urge the base plate against the articulated arm to secure the kinematic mount. The wave spring can then mechanically isolate the base plate from the articulated arm.

  • Patent number: 8082674
    Abstract: A probe, connectable to a machine tool, has an electric generator and a driving element. The electric generator supplies an electric or electronic circuit with electric power, and the driving element is capable of relative rotation with respect to the stator of the electric generator. The driving element is not connected to any external energy source and can be set in rotation simply by activating the rotary axis of the machine tool. The driving element is either rotatably mounted on the probe itself or fixed on the reference table of the machine tool. The probe requires no additional connections to the machine tool on which it is mounted, besides the connection to the rotary spindle, which can be realized with a conventional tool-holder with a standardized tapered shank. The probe is fully compatible with standard probes and can be mounted and used with standard tool-holders without any adaptation.

  • Patent number: 7956622
    Abstract: A method for the signal processing of capacitive measurement scales intended for the measurement of lengths or angles, consisting of two parts moveable relative to each other provided with electrodes that together form condensers, whose magnitudes are variable and depend on the relative position as specified by a sinusoidal relationship between the two parts. The first part has n electrodes evenly distributed over one measurement period and the second part has one electrode per measurement period. The electrodes in the first part are fed with n alternating voltages whereby the time displacements of the alternating voltages relative to each other are t 0 n , , where t0 is the length of the period of the alternating voltage. The electrode of the second mobile part captures a signal composed of one or several of the alternating voltages and the amplitude composition of the signal depends on the relative position between the two parts.
