A sensor blockchain system is provided. The sensor blockchain system includes a plurality of sensor-data-loggers, wherein each sensor-data-logger includes a memory device which utilizes FN tunneling. An input to the sensing interface alters the geometry of the energy barrier to change the electron leakage rate and the current state of the sensor-data logger is determined by an initial state of the sensor-data-logger, the predetermined electron leakage rate, and any inputs to the sensing interface. The sensor-data-loggers may be synchronized to an initial state. The synchronization will be maintained when they are all subjected to similar changes in environmental conditions in a supply chain. Desynchronization will occur due to changes in environment, including changes in temperature.

Aspects of the disclosure provide for automatically generating labels for sensor data. For instance, first sensor data, for a vehicle may be identified. This first sensor data may have been captured by a first sensor of the vehicle at a first location during a first point in time and may be associated with a first label for an object. Second sensor data for the vehicle may be identified. The second sensor data may have been captured by a second sensor of the vehicle at a second location at a second point in time outside of the first point in time. The second location is different from the first location. A determination may be made as to whether the object is a static object. Based on the determination that the object is a static object, the first label may be used to automatically generate a second label for the second sensor data.

A method comprises emitting detection radiation into a container; receiving a reflection of the emitted radiation from contents of the container; interpreting the received reflection to determine the contents of the container.

The present invention is a system for measuring at least one property of concrete that comprises: a housing having an inner cavity, said housing being embeddable into concrete upon deployment of said system in the field; a controller having a form that fits inside said cavity, said controller being retrievable from said cavity after said system is deployed; a sensor detachably connected to the controller such that the sensor becomes embedded into concrete upon said deployment of said system; wherein said system is capable of measuring a property of concrete upon deployment. The present invention also provides a novel method of measuring the strength of concrete comprising attaching the system as described above to a supporting element of a construction structure; immersing said housing and said sensor into concrete whereby the sensor is completely embedded inside the concrete; and measuring data related to the strength of concrete using the sensor and then transmitting the data wirelessly to a remote server.
