A method of data acquisition for health management of systems is provided. The method includes receiving, at a remote node, analog data from one or more sensors configured to monitor a health characteristic of a system, converting, at the remote node, the analog data into digital data, time stamping the digital data with the remote node, recording the digital data in a memory of the remote node, wherein the memory is a ring buffer, transmitting, from the remote node to a central device, requested digital data upon receiving a request related to a triggering event, and synchronizing the transmitted data at the central device based on the time stamp of the requested digital data to generate synchronized data.

The invention relates to a method for operating a sensor arrangement in a motor vehicle (1) on the basis of a DSI protocol, wherein the sensor arrangement (2) has a central unit (3) as a master and a plurality of sensor units (S1, S2, S3, S4, S5, S6) each having a receiver (6) as slaves controlled by the master, and the central unit (3) and the sensor units (S1, S2, S3, S4, S5, S6) are connected to a bus cable (4). In the method, communication takes place via the bus cable (4) between the central unit (3) and the sensor units (S1, S2, S3, S4, S5, S6) in such a way that the master selects whichever slaves are assigned time slots (ZS1, ZS2, ZS3, ZS4, ZS5, ZS6) for sending data. The time slots (ZS1, ZS2, ZS3, ZS4, ZS5, ZS6) are therefore not statically assigned but dynamically assigned. Specifically, it is thus the case that for a particular measurement not all slaves receive an assigned time slot for sending data. Such a method is therefore provided, in which a communication between master and slaves is normally possible with a high bandwidth.

Methods and systems of correcting operation of multiple modules are described. The methods include generating a first dual-tone signal in a first module and transmitting the first dual-tone signal to a second module. A second dual-tone signal is generated in the second module and transmitted to the first module. The first module determines a first phase of the received second dual-tone signal and the second module determines a second phase of the received first dual-tone signal. Operation of one or both of the first and second modules is corrected based on the determined first phase and the determined second phase.

Systems, methods, and apparatuses are discussed that enable robust, high-speed communication of sensor data. One example system includes a sensor bus, an electronic control unit (ECU), and one or more sensors. The ECU is coupleable to the sensor bus and configured to generate a synchronization signal, and is configured to output the synchronization signal to the sensor bus. The one or more sensors are also coupleable to the sensor bus, and at least one sensor of the one or more sensors is configured to sample sensor data in response to the synchronization signal and to output the sampled sensor data to the sensor bus.
