  • Publication number: 20220346425
    Abstract: The present application relates to processing of Cannabis material, particularly on a large scale, such as at an industrial level Cannabis is typically a controlled and regulated substance, and has traditionally been processed in low quantities. A human-based manual and/or labour-intensive processing implementation is not scalable, and is therefore infeasible at an industrial level.

  • Patent number: 11466395
    Abstract: A laundry appliance includes a cabinet having a top panel that defines an aperture for selectively accessing a treatment chamber defined within the cabinet. A lid is rotationally operable relative to the aperture of the top panel between open and closed positions. Hinge assemblies extend between the lid and the top panel. The hinge assemblies include a first hinge assembly. A second hinge assembly is selectively retractable into the lid to a retracted position. A biasing member biases the second hinge assembly out to an extended position. At least the second hinge assembly is operable to the retracted position to bypass a portion of the top panel to define an installed position where the first and second hinge assemblies are engaged with respective hinge receptacles of the top panel.

  • Patent number: 11431161
    Abstract: Disclosed herein are systems and methods for safe electric power delivery protection within a high-risk area while maintaining electric power availability in non-faulted areas. Fault signals from wireless sensors are used at a recloser to block reclosing onto a faulted high-risk zone. Fault signals from wireless sensors are used at a recloser to permit reclosing when the reclosing operation will not close onto a fault location within the high-risk zone. Portions of the power system may be selectively openable by sectionalizers. When a fault is reported by a wireless sensor as being on a portion of the power system selectively openable, a recloser may be permitted to attempt a reclose operation affecting the high-risk zone and the selectively openable portion.

  • Publication number: 20220172052
    Abstract: Described herein are techniques of training a machine learning model and performing inference using an analog processor. Some embodiments mitigate the loss in performance of a machine learning model resulting from a lower precision of an analog processor by using an adaptive block floating-point representation of numbers for the analog processor. Some embodiments mitigate the loss in performance of a machine learning model due to noise that is present when using an analog processor. The techniques involve training the machine learning model such that it is robust to noise.

  • Publication number: 20220148101
    Abstract: Systems and methods for determining how to dispatch power to a property from a generator are provided. According to certain aspects, a controller associated with the generator may retrieve or access a set of data indicating time of use rates associated with utility power, performance characteristics of the generator, and/or energy usage data. Based on the data, the controller may determine a set point corresponding to when it may be beneficial to dispatch generator power to the property instead of utility power. At the set point, the controller may facilitate supplementing power from utility power with power from the generator. Additionally, the controller may collect usage and performance data associated with dispatch of the generator power.

  • Publication number: 20220129835
    Abstract: The present application relates to the production of cannabis products, particularly on a large scale, such as at an industrial level.

A human-based manual and/or labour-intensive implementation is not scalable, and is therefore infeasible at an industrial level. Disclosed herein are computer systems for inventory control, security systems, and computer methods for facilitating traceability from a cannabis product back to a batch of cannabis plants.

  • Publication number: 20220120639
    Abstract: Methods, systems, and devices for analyzing vibration data to determine and mitigate an occurrence of an anomaly at an industrial asset. A device may obtain and preprocess vibration data, which may include grouping the vibration data according to respective time intervals, and the device may filter the grouped data to obtain the most recent measurement readings. The device may use an anomaly detection algorithm to detect outliers in the datasets for each group of vibration data and compare an amplitude of the outliers to a threshold for the respective group. The device may determine that the vibration data includes an anomaly based on quantities of outliers in first and second subsets of the vibration data that are within a detection window. The device may generate a report including an indication of the anomaly and transmit the report to an operator or engineer for the facility.

  • Patent number: 11261265
    Abstract: The present invention is directed to an acrylic polymer prepared from a reaction mixture comprising: (i) an ethylenically unsaturated monomer comprising hydroxyl functional groups; (ii) an ethylenically unsaturated monomer comprising polydialkylsiloxane groups; (iii) an ethylenically unsaturated monomer comprising carboxylic acid functional groups or amine functional groups; and (iv) a reactive diluent that is reactive with the ethylenically unsaturated monomer (iii). The reactive diluent (iv) is present initially in the reaction mixture as a medium in which the monomers polymerize. The present invention is further directed to aqueous polymeric dispersions prepared therefrom and aqueous, curable film-forming compositions prepared from the dispersions. The curable film-forming compositions are low VOC and are useful in methods of mitigating dirt build-up on a substrate.
