Methods and devices for identifying the type of occupancy of a supporting surface
First Claim
1. A method for identifying the type of occupancy of a supporting surface, using sensor signals, comprising:
- storing the sensor signals recorded at predefined instants ti, or quantities derived from the sensor signals, in a memory as stored values, sti, making available for evaluation the stored values sti, from a recent past, and deriving the type of occupancy from these stored values.

Abstract
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. The sensor signals si, which are recorded at predetermined instants ti, or quantities derived therefrom, are continuously stored in a memory (4) 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.

33. A system for identifying the type of occupancy of a supporting surface, comprising:
-
at least three force sensors or at least one axis of rotation in conjunction with at least one force sensor arranged on the supporting surface;
measurement electronics via which the at least three force sensors or the at least one axis of rotation in conjunction with the at least one force sensor measure forces acting on the supporting surface; and
a control unit that controls the system as a function of measured values as determined by the measurement electronics;
a memory in communication with the measurement electronics such that sensor signals recorded at predefined instants ti, or quantities derived from the sensor signals, are continuously stored as stored values sti, with the stored values sti from the recent past are available for evaluation at any time; and
a data processing unit that determines the type of occupancy by evaluating the stored values in the memory using at least two independent calculation methods or using a neural network. - View Dependent Claims (34, 35, 36)
