Patent number: 8391710Abstract: An optical sensor system comprises one or more optical sensor devices, a master device and an electrical bus connecting the sensor devices to the master device. The bus comprises a signal daisy chain for the transmission of synchronization events. The sensor devices are adapted to detect a synchronization event at a signal input terminal, to time an optical activity based on this synchronization event and to provide at a signal output terminal a synchronization event delayed by an offset time with respect to the detected synchronization event. A property of the synchronization events provided by the sensor devices is indicative of an output value of the respective sensor device, corresponding to a state of an optical section to which the sensor is sensitive.Type: GrantFiled: September 3, 2009Date of Patent: March 5, 2013Assignee: Optosys SAInventors: Peter Heimlicher, Charles Rhême, Pierre-Yves Dénervaud, Roland Bochud

Publication number: 20120256096Abstract: A method and a device for monitoring objects moving along a trajectory. The objects include a section that is transparent or translucent. The objects subsequently cross a light beam at the section. The presence or absence of an object is determined during a transitional time period during which substantially no light or light within a wavelength range substantially untransmittable through the section is detected. A monitoring device generates an output signal based on the light detection indicating the presence or absence of an object.Type: ApplicationFiled: March 9, 2012Publication date: October 11, 2012Inventors: Peter HEIMLICHER, Charles RHÊME

Patent number: 8179124Abstract: The invention relates to an inductive proximity sensor for embedding in a mild steel mounting plate, comprising an enclosure with a front wall of synthetic material forming a sensing face at a front end of the enclosure, an oscillator comprising a sensor coil with a core made of a material with a relative magnetic permeability larger than 1, typically a ferrite, which is arranged within the enclosure behind the front wall so that an open side of the core is directed towards the sensing face in order to direct the magnetic field of the coil towards a target in front of the sensing face, a hollow cylindrical metal member arranged perpendicular to the sensing face and surrounding the core, and a measuring circuit for measuring an attenuation of the oscillator due to eddy currents. The core is radially surrounded by a metal layer with a low electrical resistivity of less than 15 ??·cm and with a thickness of less than 40 ?m, in order to improve the embeddability of the sensor.Type: GrantFiled: July 9, 2009Date of Patent: May 15, 2012Assignee: Optosys SAInventors: Marc De Huu, Peter Heimlicher, Charles Rhême, Philippe Venier

Patent number: 5764351Abstract: The method for the differential measurement of an angle of incidence of a luminous beam uses a polarized light beam which is passed twice through a birefringent plate followed by a polarizing analyzer in order to obtain a succession of interference fringes. The orientation or the mutual spacing between the crests of said fringes, which are a direct function of the measured angle (.gamma.), are analyzed by means of a suitable detector and of an electronic analyzing circuit. The measuring device comprises a single polarizing analyzer, a birefringent plate which is followed by a mirror in order to reflect the light beam through said birefringent plate a second time, and means for detecting the variations of the luminous intensity including an electronic analyzing circuit.Type: GrantFiled: July 19, 1996Date of Patent: June 9, 1998Assignees: Optosys SA, Charles RhemeInventor: Charles Rheme

Patent number: 5182612Abstract: For measuring an angle of incidence of a luminous beam, one employs a polarized luminous beam which is brought to pass though a birefringent plate followed by an analyzing polarizer, in order to obtain succession of fringes of interference, and one analyzes by means of an appropriate detector and an electronic circuit the spacings between the crests of said fringes, said spacings being a direct function of the angle to be measured. One can utilize a measuring device of an angle of incidence for measuring the distance between said device and a reflecting surface of the object to be measured, by determining for a certain position of the object a spacing of reference between the crests of the fringes of interference and by measuring the variations of the spacings as a function of the position of the object, in order to display them in units of length.Type: GrantFiled: May 23, 1991Date of Patent: January 26, 1993Inventor: Charles Rheme
