Abstract: This disclosure describes systems, methods, and devices related to providing real-time response strategies in a supply chain. A system may be configured to obtain first sensor data collected from a first tracking device associated with a first asset, determine a first set of external data associated with the first asset, determine, based at least in part on the first sensor data and the first set of external data, a probability of failure and a mode of failure, and responsive to a determination that the probability of failure exceeds a failure threshold: determine a mitigation for the mode of failure that is available based at least in part on the first sensor data and the first set of external data, determine one or more real-world actions corresponding to the mitigation that, if performed, remediate the mode of failure, and cause the one or more real-world actions to be performed.

Abstract: This disclosure describes systems, methods, and devices related to programmatically updating the status of assets tracked in a supply chain environment. A system may be configured to obtain first sensor data collected from a first tracking device associated with a first asset, determine asset workflow information associated with the first asset, determine an intelligence engine configured to generate an inference of a status associated with the first asset, determine the status associated with the first asset, wherein the status is determined by the intelligence engine based on the first sensor data and the asset workflow information, and store the status of the first asset in an asset tracking database.

Abstract: A computer-implemented reinforcement learning neural network system that learns a model of rewards in order to relate actions by an agent in an environment to their long-term consequences. The model learns to decompose the rewards into components explainable by different past states. That is, the model learns to associate when being in a particular state of the environment is predictive of a reward in a later state, even when the later state, and reward, is only achieved after a very long time delay.

Abstract: Examples described herein relate to a method and a system for removing the common-mode current. The receiver includes a photodetector, a common-mode adjustment circuit, an analog front-end, an eye scan circuit, and a control unit. The photodetector generates an input photocurrent responsive to a received optical signal. The common-mode adjustment circuit generates an adjusted input current based on the input photocurrent. The analog front-end generates a differential voltage based on the adjusted input current. Based on the differential voltage, the eye scan circuit generates an eye scan information defining a first outer eye and a second outer eye in an eye diagram. The control unit tunes the common-mode adjustment circuit based on a relative height metric of a first height of the first outer eye and a second height of the second outer eye to remove a portion of the common-mode current from the input photocurrent.

Abstract: Examples described herein relate to a receiver training method. To configure a static gain for at least one static gain amplifier and a target amplitude for a dynamic gain amplifier, a dynamic gain adjustment is disabled and the dynamic gain amplifier is configured to apply a predetermined fixed gain to the static gain amplified signal to generate a test signal. Furthermore, an effective static gain magnitude for at least one static gain amplifier and an effective amplitude for the test signal are determined based on a link performance metric. The static gain is set to the effective static gain magnitude, and a target amplitude for the dynamic gain amplifier is set to the effective amplitude. Then, the dynamic gain adjustment may be enabled to maintain an amplitude of a dynamic gain amplified signal at an output of the dynamic gain amplifier at the target amplitude by varying the dynamic gain.

Abstract: Examples relate to determining a sampling threshold of a receiver (e.g., SERDES receiver). In particular, the examples relate to determining an updated sampling threshold of the receiver based on a reference sampling threshold of the receiver. A controller may determine the reference sampling threshold based on the training sequence and determine an upper voltage level and a lower voltage level of a voltage range based on the reference sampling threshold of the receiver. The controller then narrows the voltage range based on upper voltage accumulated hit rate and a lower voltage accumulated hit rate to determine the updated sampling threshold of the receiver.

Abstract: According to an example, a transmitter transmits a plurality of optical signals of multiple wavelengths via an optical link to a receiver. An optical link tuner coupled to the optical link groups the plurality of optical signals into a first group of optical signals and a second group of optical signals, where the first group of optical signals has a first wavelength range and the second group of optical signals has a second wavelength range. The optical link tuner adjusts link tuning parameters associated with the first group of optical signals during a first phase, such that the second group of optical signals is propagated to the receiver without modifications to link tuning parameters associated with the second group, where during the first phase the receiver is to detect unplugging of the optical link based on the second group of optical signals.
