Abstract: The devices and methods leverage harmonics to resolve, separate, and identify devices. The devices and methods use the harmonic patterns associated with a frequency modulating (FM) signal to discern and extract information from the FM signal using correlation learning in a crowded spectrum space where the nodes are transmitting simultaneously on multiple channels. The methods and devices leverage harmonics to resolve, separate, and/or identify wireless communication devices.

Abstract: A tracking system for a food commodity supply chain includes a tracking device and a computing device. The tracking device is mounted to a conveyance structure that is configured to receive a unit load of a food commodity. The tracking device includes a sensor to track an environmental condition of an environment of the tracking device while the tracking device is traveling along the food commodity supply chain. The computing device is configured to receive an environmental value of the environmental condition sensed by the sensor, process the environmental value to determine whether the environmental condition is within a predetermined environmental range, and transmit an alert when the environmental condition falls outside the predetermined environmental range. The alert includes a suggested interventive action based on the environmental condition that falls outside the predetermined environmental range.

Abstract: A traceability system for a bulk commodity supply chain is provided. The system includes a tracking device, a location determination subsystem, and at least one computing device having at least one processor. The location determination subsystem is configured to determine positional information of the tracking device while placed in a bulk commodity traveling along the bulk commodity supply chain. The processor receives the positional information from the location subsystem, extracts positional values from the positional information, and processes the positional values to identify motion primitives. A modeling tool is applied to the identified motion primitives to produce a positional path of the tracking device, which is output, for example, via a user interface. The positional path represents travel of the bulk commodity along the supply chain.

Abstract: A computing system including a processor configured to receive training data including, for each of a plurality of training timesteps, training forecast states associated with respective training-phase agents included in a training supply chain graph. The processor may train a reinforcement learning simulation of the training supply chain graph using the training data via policy gradient reinforcement learning. At each training timestep, the training forecast states may be shared between simulations of the training-phase agents during training. The processor may receive runtime forecast states associated with respective runtime agents included in a runtime supply chain graph. For a runtime agent, at the trained reinforcement learning simulation, the processor may generate a respective runtime action output associated with a corresponding runtime forecast state of the runtime agent based at least in part on the runtime forecast states. The processor may output the runtime action output.

Abstract: A wearable radio frequency receiver device is provided, which includes a receiver antenna configured to receive an interrogation signal from a transmitter. The receiver device further includes a sensor coupled to the receiver antenna and configured to receive a physiological input from a user wearing the device and generate a sensor signal based on the physiological input, and a modulator configured to perform direct modulation on the received interrogation signal based on the sensor signal to encode the physiological input in the directly modulated interrogation signal. The receiver antenna may be configured to reflect at least a portion of the directly modulated interrogation signal as backscatter radiation. A transceiver including a transceiver antenna may be provided to receive the directly modulated interrogation signal, and the modulation receiver may be configured to process the directly modulated interrogation signal and output a decoded physiological input.
