    Abstract: Systems and methods for predicting pest susceptibility, comprising steps to receive geocoded geospatial image data of a crop field from sensors, receive microclimate data of the crop field, determine a crop vigor map for the crop field, and then generate a pest susceptibility map utilizing a risk model based on the crop vigor map and the microclimate data. The pest susceptibility map comprises a measure of a susceptibility of a crop in the crop field to one or more crop pests at one or more locations. In some embodiments, the method also comprises steps to generate a treatment plan (e.g., pesticide application) and to estimate an anticipated return on investment (ROI). The system therefore leverages remote-sensed data, machine data, analytics, and machine learning to enable farmers to predict, prevent, and control the outbreak of crop pests to greatest economic effect. Such a system addresses a fundamental problem in agriculture.

  • Patent number: 10838058
    Abstract: Architecture and techniques for identifying types of objects based upon disruption of signal strength of millimeter-wave (mmW) transmitted signals caused by objects interfering with or blocking transmitted signals within a wireless communication network. In particular, types of objects may be identified based upon drops in signal strength due to objects moving between a transmission point and a receiving device. Based on factors including one or more of a size of an object, materials that make up the object, etc., the object causes a drop in received signal strength, thereby causing a change in a pattern of received signal strength. The changed pattern may be compared with base patterns that are correlated with a type or identity of an object in order to identify the object.

  • Patent number: 10809412
    Abstract: A WEM-based method for deep resource detection using sky waves refers to the technical field of deep resource detection. The proposed method of deep detection using sky waves improves the traditional “atmospheric-lithosphere” half-space propagation theory into a full-space “sky wave” theory of “ionosphere-atmosphere-rock layer”, that is, the influence of the ionosphere and the displacement current in the air are taken into consideration to obtain a new precise expression of “sky wave” response, which is suitable for full space, slow attenuation and long distance propagation. A receiving device for sky wave signal has been developed. Through theoretical model calculation and actual data measurement, it is known that it is possible to use the sky wave for detection within the scope of China's national territory to realize the high-precision electrical structural exploration within a depth of 10 kilometers and open a new era of artificial source electromagnetic detection.
