A weighing device having a plurality of digital weighing cells (), each including a sensor connected to a force transmission unit (), each generating a digital measurement value corresponding to a transmitted force at a measurement time point, and including a data processing device that converts the digital measurement values to transmission units configured to be transmitted over a data communications line () to a central control unit () connected to all weighing cells for analysis of the transmission units. The central control unit () calculates a digital combination value based on the transmission units originating from the various weighing cells (), the combination value representing a weight force with which the weighing device () is loaded at a weighing time point. The conversion of the measurement values to transmission units involves a pairing of each converted measurement value with a time value.

Weighing device having a plurality of digital weighing cells providing digital measurement values and associated time values to a central control unit, weighing cell, and method

A method and device for identifying the type of occupancy of a supporting surface, particularly of a motor vehicle seat (), with the aid of force sensor-assisted signals. The sensor signals s, which are recorded at predetermined instants t, or quantities derived therefrom, are continuously stored in a memory () in such a manner that, the sensor signals from the recent past, or the quantities derived therefrom are available for analysis at any time, and that the type of occupancy is derived from these stored values using at least two independent calculation methods or using a neural network.
