Various embodiments of the present invention provide methods, systems, apparatus, and computer program products for synchronizing data across at least two sensors. In one embodiment, first sensor data, which includes a universal time stamp from a universal time source, is recorded from at least one first sensor and second sensor data, which does not include a universal time stamp from a universal time source, is recorded from at least one second sensor. The first sensor data is correlated with the second sensor data, and a universal time that corresponds with the data from the second sensor is determined at least in part based on the correlation between the first sensor data and the second sensor data.

A Wireless Subterranean Soil Monitoring System. The system measures the complex permittivity around a subterranean antenna, and then responsively adjusts the antenna's tuning circuit according to the measured permittivity. Once tuned, the system will then execute the transmission of the probe data. Furthermore, the antenna design is adapted for subterranean use to further reduce the de-tuning effect of the adjacent soil.

A method for detecting the malfunction of a software solution configured to generate data representing the instant of interruption of fuel injection of an internal combustion engine. The method comprises acquiring data by a data acquisition device which is connected to a measurement device fixed to an injector body and configured to emit data representing closure instants of an injection nozzle, recording the data generated by the software solution and the data emitted by the measurement device, over a predetermined duration, synchronizing the data generated by the software solution and the data emitted by the measurement device, and comparing the data generated by the software solution and the data emitted by the measurement device, the software solution being considered to be malfunctioning when they do not satisfy predefined criteria.

An automotive sensor integration module including a plurality of sensors which differ in at least one of a sensing period or an output data format, an interface unit configured to receive pieces of detection data outputted from the plurality of sensors and convert the received detection data into a predetermined data format, and a signal processing unit configured to simultaneously output pieces of converted detection data from the interface unit on the basis of the sensing period of one among the plurality of sensors.

As sensor readings are received from a hardware sensor, each sensor reading is stored within a buffer along with a system timestamp of a system clock indicating when the sensor reading was received. Each sensor reading includes a sensor timestamp of a sensor clock indicating when the sensor reading occurred at the hardware sensor. Responsive to receipt of each sensor reading, a synthetic timestamp compensating for skew between the system clock and the sensor clock is generated and applied to the sensor reading. The synthetic timestamp is generated based on an average skew of the sensor readings within the buffer and an initial system timestamp indicating when a first sensor reading was received.
