In at least one illustrative embodiment, a method for contaminant detection includes distributing multiple magnetostrictive sensors on a nonmagnetic index plate. The index plate includes multiple wells formed in a top surface that are each sized to receive a magnetostrictive sensor. The method further includes placing a magnetic backing plate below the index plate, inverting the index plate and the magnetic backing plate, and then placing the inverted index plate on a sample surface. The sample surface may be two-dimensional food such as fresh vegetable leaves. The method may further include placing the index plate and the magnetic backing plate on a nonmagnetic cover plate that is positioned above a sensor coil. The method further includes removing the magnetic backing plate, removing the index plate, and applying a varying magnetic field with the sensor coil to a magnetostrictive sensor positioned on the cover plate. Other embodiments are described and claimed.

Systems, apparatus, and methods for transacting, recording, validating and/or verifying agricultural products. The 2018 Farm Act rescinded industrial hemp from Schedule I of the Controlled Substances Act (CSA). Although industrial hemp has a variety of uses, the Government's biggest concern is the ingestion of tetrahydrocannabinol (THC) and cannabidiol (CBD). Commercial regulation typically balances a variety of factors: e.g., consumer protection, regulatory overhead, market competition, tax revenue, public policy, etc. In contrast, law enforcement has a singular purpose, and may go to extraordinary lengths to stop criminal activity. Various embodiments described herein provide a blockchain ledger-based supply chain that allows many commercial and regulatory entities to independently cooperate. Every transaction is permanently and transparently recorded within a chain-of-custody; the chain-of-custody enables a traceability. A variety of new applications are enabled by the blockchain ledger-based supply chain.

A permeation estimation apparatus includes an interface configured to connect to a sensor that measures a concentration of a component, of a soaked material, that is eluted in a soaking solution in which the soaked material is soaking, and a controller configured to acquire the concentration of the component from the interface and estimate the degree of permeation of the soaking solution with respect to the soaked material based on the measurement result of the concentration of the component.

Embodiments of a water detection apparatus are disclosed that can detect characteristics of food products. The apparatus may include a conveying mechanism configured to move a food product through an aperture in the apparatus, a transmitter coil configured to transmit a signal within the aperture, and a receiver coil configured to receive the signal altered by the food product, and a signal processing unit configured to determine an output value associated with the food product moving through the aperture. The output value can be based, at least in part, on the signal and the altered signal. The output value can corresponds to a characteristic of the food product.

Embodiments of systems and approaches for managing post-harvest crop quality and pests are described. Such a system may include a plurality of edge devices each comprising sensor components and collectively forming a mesh network, for measuring the local physical environment within stored crops and, for example, transmitting the measurements to a service from within the crop storage area. In certain embodiments, such a system may be used to manage post-harvest crops and storage areas—for example, approaches are described for determining fumigation treatment duration, determining phosphine dosage, determining heat treatment duration, and determining safe storage time for crops.

In one aspect, a system for monitoring crop fill-levels of transport receptacles includes a crop transport receptacle defining a storage volume configured to receive harvested crops, and a sensor assembly provided in association with the crop transport receptacle. The sensor assembly is configured to generate capacitance-related data associated with a fill-level of the harvested crops within the storage volume. In addition, the system includes a computing system communicatively coupled to the sensor assembly. The computing system is configured to receive crop data associated with a dielectric constant of the harvested crops within the storage volume. The computing system is further configured to determine the fill-level of the harvested crops within the storage volume based at least in part on the capacitance-related data and the crop data.

An optical system operating in the near or short-wave infrared wavelength range identifies an object based on water absorption. The system comprises a light source with modulated light emitting diodes operating at wavelengths near 1090 and 1440 nanometers, corresponding to lower and higher water absorption. The system further comprises one or more wavelength selective filters and a housing that is further coupled to an electrical circuit and a processor. The detection system comprises photodetectors that are synchronized to the light source, and the detection system receives at least a portion of light reflected from the object. The system is configured to identify the object by comparing the reflected light at the first and second wavelength to generate an output value, and then comparing the output value to a threshold. The optical system may be further coupled to a wearable device or a remote sensing system with a time-of-flight sensor.
