  • Patent number: 11817807
    Abstract: The present invention provides a method and system for controlling the temperature of an electric motor by adjusting the electric losses in the motor. In an embodiment, the required load on the motor is determined and a first motor voltage is provided to meet the required load. A predetermined temperature set point for the motor is compared against the temperature of the motor and based on the temperature of the motor and the predetermined temperature set point, a secondary motor voltage is determined. The motor voltage may then be adjusted based on the calculated voltage and the motor load measurement adjusted based on the measured motor speed and actual motor voltage.

  • Publication number: 20230360376
    Abstract: Semantic fill techniques are described that support generating fill and editing images from semantic inputs. A user input, for example, is received by a semantic fill system that indicates a selection of a first region of a digital image and a corresponding semantic label. The user input is utilized by the semantic fill system to generate a guidance attention map of the digital image. The semantic fill system leverages the guidance attention map to generate a sparse attention map of a second region of the digital image. A semantic fill of pixels is generated for the first region based on the semantic label and the sparse attention map. The edited digital image is displayed in a user interface.

  • Publication number: 20230314318
    Abstract: Apparatuses, methods, and systems for detecting a sample are disclosed. One method includes generating, by a tunable light source, a beam of electro-magnetic radiation, wherein a wavelength of the beam of electro-magnetic radiation is tuned to operate at a plurality of wavelengths. At least a portion of the beam of electro-magnetic radiation is directed to pass through the sample and a reference substance. The system detector is configured to sense at least the portion of the beam of electro-magnetic radiation after passing through the sample and the reference substance. The processor operates to receive information related to intensity or amplitude of the sensed beam of electro-magnetic radiation after passing through the sample and the reference substance and detect an amount of the sample based on the received information related to the intensity or amplitude of the sensed beam of the electro-magnetic radiation.

  • Patent number: 11769281
    Abstract: Vector object transformation techniques are described that support generation of a transformed vector object based on a first vector object and a second vector object. A plurality of paths for a first and second vector object, for instance, are generated. Corresponding paths are determined by detecting which of the plurality of paths from the first vector object correspond to which of the plurality of paths from the second vector object. A mapping of control points between the first and second vector objects is generated. Using the mapping, a transformation of the first vector object is generated by adjusting one or more control points of the first vector object. As a result, the transformed vector object includes visual characteristics based on both the first vector object and the second vector object.

  • Publication number: 20230271930
    Abstract: Processes are described for obtaining highly purified tetrahydrocannabinolic acid (THCa) from Cannabis. Solvent extraction is performed on plant material or extract, followed by removal of impurities using sequential liquid-liquid extractions to purify cannabinoid carboxylic acids therefrom based on chemical properties of carboxylate salts. The product liquor, comprising THCa in solvent, is largely free of impurities, and high in THCa. Further steps can be conducted to obtain a highly enriched solution using chromatography and subsequent crystallization of THCa in 99% purity. THCa can be used as starting material for other products that include THC by decarboxylation. Optionally, triglyceride extraction of a washed aqueous phase can be used to prepare a THCa composition without chromatographic purification. A pre-processing aqueous extraction with pH manipulations may be used to remove biomass prior to solvent extraction, while maintaining THCa and optionally other cannabinoid acids.

  • Publication number: 20230137233
    Abstract: Generating a vector representation of a hand-drawn sketch is described. To do so, the sketch is segmented into different superpixel regions. Superpixels are grown by distributing superpixel seeds throughout an image of the sketch and assigning unassigned pixels to a neighboring superpixel based on pixel value differences. The border between each pair of adjacent superpixels is then classified as either an active or an inactive boundary, with active boundaries indicating that the border corresponds to a salient sketch stroke. Vector paths are generated by traversing edges between pixel vertices along the active boundaries. To minimize vector paths included in the vector representation, vector paths are greedily generated first for longer curves along active boundaries until each edge is assigned to a vector path. Regions encompassed by vector paths corresponding to a foreground superpixel are filled to produce a high-fidelity vector representation of the sketch.

  • Patent number: 11631207
    Abstract: Vector object stylization techniques from raster objects are described that support editing of vector objects in a manner that maintains an underlying mathematical representation of object. A raster object, for instance, is generated from an edited version of an output of a vector object. This raster object, along with the vector object are received as inputs by a vector conversion system. These inputs are utilized by the vector conversion system to generate a stylized vector object having a visual appearance that mimics and simulates a visual appearance of the raster object. As a result, the stylized vector object provides a mathematical representation of the raster object.
