| 20110175600 | MAGNETIC ANGULAR POSITION SENSOR FOR A COURSE UP TO 360 DEGREES - The invention relates to an angular position sensor comprising a moving element consisting of at least one essentially cylindrical permanent magnet ( | 07-21-2011 |
| 20110043194 | VARIABLE RELUCTANCE POSITION SENSOR - A variable reluctance analog position device designed to determine the position variation of a target made from a ferromagnetic material. The device includes at least one magnet, the target and the magnet defining a gap therebetween. A magnetosensitive element detects induction variation produced in the gap by relative movement of the target relative to the magnet. The magnet is magnetized in a direction essentially perpendicular to the front surface of the magnet, which defines one edge of the gap. The magnet includes a cavity open at the front surface thereof and the magnetosensitive element is housed in the cavity. Moreover, the target is provided with a specific geometric configuration determined such that the induction variation according to the position of the target corresponds to a pre-defined function. | 02-24-2011 |
| 20110031824 | GEAR MOTOR INCLUDING A COMPACT MULTIPLE-PHASE ELECTRIC MOTOR - The invention relates to a gear motor including a multiple-phase electric motor formed by a stator portion excited by electric coils and by a rotor having N pairs of poles radially magnetised in alternating directions, the stator portion including two angular sectors alpha- | 02-10-2011 |
| 20100194385 | NON-CONTACT MULTI-TURN ABSOLUTE POSITION MAGNETIC SENSOR COMPRISING A THROUGH-SHAFT - The invention relates to an absolute position magnetic sensor for measuring the angular position, on a theta course, of a shaft passing through said sensor and comprising at least two systems for detecting the position of the shaft. Said invention is characterised in that: at least one of the detection systems generates a signal according to a “periodical” function of the theta/n period giving the periodical angular position of said shaft; at least one of the detection systems generates an absolute signal on a theta course of the shaft; and theta and n fit the equation: *theta/n=360*n>1. | 08-05-2010 |
| 20080250873 | Position Sensor Which Is Intended, in Particular, for Measuring Steering Column Torsion - The invention relates to a position sensor which is intended, in particular, for detecting a steering column torsion. The invention consists of: a first magnetic rotor structure ( | 10-16-2008 |
