Patent ID: 8442800

Claim:
A system for detecting an object and an event linked to the object, which system comprises a sensor field comprising two or more sensors in the vicinity of the object that are suited to the detective measurement of touch or pressure, measuring electronics that produces sensor observations by means of the sensors, and a data processing system suited for processing sensor observations, comprising a processor and a memory, wherein the data processing apparatus is arranged to detect the object and the event or events linked to the object on the basis of one or more sensor observations, wherein the system also comprises means for producing an estimate applying to the status of the object to be tracked using information recorded earlier about the status of the object and the length of time that has passed from the moment in time it describes wherein the system further comprises a structure that delimits the space and an arrival area where the system processes the observations made at a certain time, and records a new object which appears in the arrival area and links the observations to the new object, and an exit area where the system has processed the observations and has correspondingly updated the status information of the objects being tracked and wherein the system uses information about the changes in the status information of the objects to determine if an object has exited the delimited space.
