Fuente: Wipo "Sensorization" This application is directed to compressing sensor data. A computer system obtains the sensor data from a plurality of sensor devices disposed in a physical environment during a time duration, and each sensor device corresponds to a temporal sequence of respective sensor samples. For each of the plurality of sensor devices, the temporal sequence of respective sensor samples is processed to generate an ordered sequence of respective sensor data features defining a respective parametric representation of the temporal sequence of respective sensor samples, independently of a sensor type of the respective sensor device. The computer system detects one or more signature events within the time duration based on the respective parametric representations of the plurality of sensor devices, and generates one or more information items characterizing the one or more signature events detected in the sensor data.
