Patent number: 9243898Abstract: A position measurement system for determining 2D displacement or position of a mobile element with respect to a reference frame, including: a point light; an optical mask having transparent and opaque areas defining a repetitive pattern on at least one side of its surfaces; an imager, fixed to a mobile element, including integrated electronic circuits allowing detection, computing and analyzing of a shadow projected by the optical mask. The position measurement system includes an optical diffuser plate between the light source and the mask. The imager, mask and diffuser plate form an assembly so as to produce a light spot created by the scattering of the incident light beam emitted by the light source on the diffuser plate. The mask positioned between the diffuser plate and imager, produces a shadow on the imager, allowing to compute and provide 2D position of the mobile element relative to the fixed reference frame.Type: GrantFiled: April 14, 2014Date of Patent: January 26, 2016Assignee: CSEM CENTRE SUISSE D'ELECTRONIQUE ET DE MICROTECHNIQUE SA RECHERCHE ET DEVELOPPEMENTInventors: Peter Masa, David Hasler, Eric Grenet, Ross Stanley

Patent number: 9035232Abstract: A method for working out the angular position of a rotating element, by using at least one fixed light source emitting a light beam in the direction of a fixed sensor, arranging the light source with respect to the rotating element and sensor to induce an interaction between the beam and sensor, and providing a value of the angular position dependent of the sensor's output signal. The method including: arranging on the path of the beam a code-disc presenting a two-dimensional pattern of transparent and opaque areas and an absolute code integral with the rotating element, using the image casted by the code-disc on the sensor for determining the eccentricity of the code-disc in dependence of the angular position of the rotating element, using the eccentricity for compensating the value of the computed angular position, and computing a corrected angular position of the rotating element.Type: GrantFiled: July 12, 2012Date of Patent: May 19, 2015Assignee: CSEM CENTRE SUISSE D'ELECTRONIQUE ET DE MICROTECHNIQUE SA-RECHERCHE ET DEVELOPPMENTInventor: Peter Masa

Patent number: 8698892Abstract: A one-dimension position measurement system includes: a first ruler having a first one-dimension binary code si applied thereon, a camera for acquiring a picture of a portion of the code si, the portion having a length of I bits, and some processing elements. Each codeword of length I of the one-dimension code si is unique within the whole code si. A codeword ai is read from the acquired picture, and the processing elements are implemented for computing an absolute position p of the codeword ai of the code si from: (I). An ad-hoc interpolation method is used to obtain a precision way below the distance between two bits of the codewords. The code si may be applied on the ruler by using some geometric primitives, a geometric primitive for encoding a “1” being different from a geometric primitive for encoding a “0”, both having the same horizontal projection. The horizontal projection is then used for fine interpolation, achieving nanometer-scale resolution.Type: GrantFiled: April 3, 2009Date of Patent: April 15, 2014Assignee: CSEM Centre Suisse d'Electronique et de Microtechnique SA - Recherche et DeveloppementInventors: David Hasler, Peter Masa, Pascal Heim, Edoardo Franzi

Patent number: 6528783Abstract: An electronic circuit for measuring the position of a spatially periodic intensity pattern of incident radiation includes an array of detectors (1); two or more correlator units (2, 3) each having arrays of capacitors (12, 13) connected to a buffer (14); and a phase angle computing unit (4). The pitch of the array of detectors (1) is smaller than the pitch of the incident intensity pattern so that the latter is oversampled, yielding high accuracy. The detector outputs (17) are weighted by respective fixed capacitance values (15, 16) which vary periodically along arrays of capacitors (12, 13), and a weighted sum of outputs for each correlator unit (2, 3) is output at its respective buffer (14). The capacitance values (15, 16) of respective correlator units (2, 3) are mutually offset by a predetermined phase shift. The analog computation using capacitor arrays (12, 13) is fast and energy efficient, and can be implemented as a VLSI circuit.Type: GrantFiled: September 7, 2001Date of Patent: March 4, 2003Assignee: Bishop Innovation LimitedInventors: Alessandro Mortara, Peter Masa, Pascal Heim, Friedrich Heitger
