Abstract: A network (1) including at least one wireless sensor (2, 3) having emitting means (8) for emitting a first signal (S11, S12), a plurality of gateways (4, 5, 6), and a network supervisor (7). The network supervisor (7) includes determining means (13) for determining for each gateway (4, 5, 6) a signal reception quality score (I111, I112, I113, I121, I122, I123) of the first signal (S11, S12) to quantify the quality of the reception of the first signal by the said gateway. The network supervisor (7) includes choosing means (14) for choosing a selected gateway (5, 6) from the plurality of gateways (4, 5, 6), the selected gateway having the highest signal reception quality score (I112, I123).

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.

Abstract: A process for determining the total pitch deviation of a position sensor fitted with a magnetic disk and a magnetic detector, the magnetic disk comprising pairs of magnetic poles, the process includes recording, over one mechanical turn, an angular signal of the magnetic intensity measured by the magnetic detector as a function of the angle of rotation of the magnetic disk, determining zero-crossing positions based on the angular signal recorded and the number of zero-crossing position determined, determining the pole pair lengths based on the zero-crossing positions, and determining the total pitch deviation based on the pole pair lengths.

Abstract: A lean signal processing method, a bearing monitoring unit and a wheel monitoring unit using the lean signal processing method are presented that are especially suitable for embedded systems. The invention is based on the basic inventive idea of digitally adjusting measured signals that are to be analyzed in different frequency bands to thereby enable to have a single common analogue front end and a single common digital spectrum analyzer back end. This will save analogue components and relax the need for memory in addition to a lean signal processing.

Abstract: A sensor module configured to detect a vibration of a mechanical component includes a base connectable to the mechanical component, at least one spacer extending from the base, and a circuit board connected to the base by the spacer such that a mechanical vibration is transmitted from the component to the base to the spacer to the circuit board. The circuit board includes a circuit and wirelessly transmits signals indicative of a detected vibration. The spacer includes a body portion and a pin portion projecting from an end of the body portion. The pin portion extends into the at least one hole, and the body portion is blocked from passing though the at least one hole by contact with a region of a first side of the circuit board surrounding the at least one hole.
