Publication number: 20120047756Abstract: 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.Type: ApplicationFiled: September 2, 2010Publication date: March 1, 2012Applicant: HEXAGON METROLOGY ABInventor: Paul Ferrari

Patent number: 8082674Abstract: 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.Type: GrantFiled: April 21, 2009Date of Patent: December 27, 2011Assignee: Hexagon Metrology ABInventors: Pascal Jordil, François Gabella

Patent number: 7956622Abstract: 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.Type: GrantFiled: October 3, 2006Date of Patent: June 7, 2011Assignee: Hexagon Metrology ABInventors: Carl-Erik Gustafsson, Steve Tveit Pedersen, Svein Johannessen
