Abstract: A sensor (2) includes a first memory (6) for storing a current version (SOFT-0) of an application software. A second memory (7) stores a predetermined sensor identifier (ID0). A third memory (8) stores a first version (SOFT-1) of the application software. A fourth memory (9) stores a flag (FL). A boot memory (5) stores an initial software (SOFT-I). A processing means (11) implements the current version (SOFT-0) of the application and the initial software (SOFT-I).

Abstract: A sensor (8) includes a plurality of modules (11, 12). Each module performs a task. The sensor (8) includes a control means (10) that (1) reads a word (WO) having a plurality of bits, with each bit being associated to the state of execution of the task performed by a module when the sensor (8) is in an active mode, and (2) switches the sensor (8) into a sleep mode when each bit (B1, B2) is in a first predetermined state. The first predetermined state of each bit is representative of the none execution of the task of the module associated to the bit.

Abstract: The device (8) for decimating samples of a continuous signal by a float number. The device includes interpolating means (11) configured to determine intermediate samples. A determining means (12) is configured to determine intermediate set of samples comprising the samples and the intermediate samples. A filtering means (13) is configured to filter the intermediate set of samples to determine one final value from an odd number of consecutive samples of the intermediate set of samples and to remove frequencies below a first cut-off frequency (F3) equal to the predetermined sampling frequency divided by two within a predetermined tuning value.
