摘要： The invention relates to a weigh sensor comprising a part (110/111/112) affixed to the housing and a load sensor (102) that is movably connected to the part affixed to the housing by means of a parallel guide consisting of a top arm (103) and a bottom arm (104). According to the invention, heating or cooling elements (120, 121) are provided, said elements locally modifying the temperature in the load sensor (102) and/or the part (110) affixed to the housing between the supporting points of the top and bottom arms relative to the rest of the weigh sensor. As a result of thermal dilation coefficients of the material of the weigh sensor, the vertical distance between the top and bottom arms is slightly modified with the purpose of adjusting corner load. This makes it possible to carry out fine adjustment of the corner load without having to perform any mechanical operations in the weigh sensor while only using electrical means.

摘要： The invention relates to a method and device for identifying the type of occupancy of a supporting surface, particularly of a motor vehicle seat (2), with the aid of force sensor-assisted signals, whereby the sensor signals si, which are recorded at predetermined times ti, or quantities derived therefrom, are continuously stored in a memory (4) in such a manner that, at each time, the sensor signals si or the quantities, which are respectively from the last time and derived from the sensor signals, are available for analysis, and that the type of occupancy is inferred on the basis of these stored values by means of at least two independent calculating methods or by means of a neuronal network.
