A device includes processing circuitry and sensor communication interface circuitry. The processing circuitry, in operation, generates one or more parameters of a regression model based on a plurality of data sets. Each data set includes an application time stamp and a sensor time stamp. Based on the one or more parameters, the processing circuitry estimates application time stamps associated with received sensor data samples. The received sensor data samples have associated sensor time stamps. The sensor communication interface circuitry is coupled to the processing circuitry. The sensor communication interface circuitry, in operation, communicatively couples the processing circuitry to a sensor. Data samples of the sensor are received by the processor via the sensor communication interface circuitry.

Device with time stamp synchronizing and related method

A sensor system includes a plurality of inertial measurement units (IMU) and a control circuit. The control circuit is configured to receive sensor data from each of the inertial measurement units two alignment the timestamps of the sensor data, and to fuse the sensor data from the various IMUs. The control circuit detects whether the sensor data indicates a high degree movement or a low degree of movement and selects a high dynamic fusion process or a low dynamic fusion process based on the detected degree of movement.
