20160139288 | DEVICE AND METHOD FOR MONITORING ACCESS TO A STORAGE AREA OF A PLURALITY OF STORAGE AREAS FOR GOODS - Embodiments of the present invention provide a device for monitoring access to a storage area of a plurality of storage areas for goods, including a measurement signal generation, detection, and evaluator. The measurement signal generator includes a signal source and a conductor loop arrangement, the detector for detecting the generated magnetic field is configured to provide a measurement signal on the basis of the detected magnetic field, and the evaluator for evaluating the measurement signal is configured to determine an instance of access to one of the storage areas on the basis of the measurement signal, to compare a determined instance of access with a target access instance, and to output a display signal on the basis of the comparison. | 05-19-2016 |
20160146635 | POSITION DETECTING DEVICE - A position detecting device includes: a magnet that has a first magnetic pole and a second magnetic pole; a magnetic sensor that detects a change in magnetic flux generated by a detection target which enters between the magnet and the magnetic sensor on the first magnetic pole side of the magnet; and a magnetic shield that has a magnetic gap between the magnet and the magnetic shield, and that includes a magnetic material which is disposed on the second magnetic pole side of the magnet. | 05-26-2016 |
20160161522 | A SENSOR-BEARING UNIT, A MECHANICAL SYSTEM COMPRISING AT LEAST ONE SUCH UNIT AND IMPLEMENTING METHODS - A sensor-bearing unit, comprising: a bearing including at least one non-rotating ring and at least one rotating ring movable in rotation around a rotation axis; an impulse ring and a sensor device for tracking the rotation of the rotating ring around the rotation axis. The impulse ring is fixed to the rotating ring. The sensor device is fixed to the non-rotating ring and includes a differential detection cell having a structural pitch. The differential detection cell is tilted and has an effective pitch different from the structural pitch. A mechanical system can such sensor-bearing unit. | 06-09-2016 |
