    摘要: An apparatus and method is provided for detecting multiple workpieces. The present invention provides a mount adaptor connected to a workpiece engaging device for engaging and manipulating a workpiece. A cell body is connected to the mount adaptor, and the cell body has an accelerometer disposed therein for measuring and signaling an acceleration value of the workpiece. A load cell is connected to the cell body and is connectable to a manipulator, wherein the load cell measures and signals a load value of the workpiece. A computer processor receives the acceleration value and the load value of the workpiece for determining the mass of the workpiece and determining whether there are multiple workpieces engaged by the workpiece-engaging device.

    摘要: The present invention provides a magnetic force sensor that can precisely detect and correct variations in a magnetic field generated by a magnetic flux generating source. Therefore, a displacement magneto-electric transducer, which detects a change in the magnetic field caused by an external force, and a fixed magneto-electric transducer, where the change in the magnetic field caused by the external force does not occur, are provided to face end sides of magnetic poles of the magnetic flux generating source. The fixed magneto-electric transducer detects a variation of the magnetic field caused by, for example, changes with time and environmental variations such as a temperature rise in the interior of the sensor. On the basis of a detection amount thereof, an operational section performs a correction operation, so that a sensitivity coefficient or an offset of the displacement magneto-electric transducer is corrected.
