Abstract: Systems, apparatus, and methods use a basic solution in a pH range to extract non-purified cannabinoids, specifically cannabinoid acids, and carboxylic acid compounds along with their decarboxylated cannabinoid counterparts from hemp plant tissue, such as biomass or flower, using automated agitation, filtrating, and draining. The systems, apparatus, and methods agitate and cause turbulence of the hemp tissue, which allows extraction of both polar and non-polar cannabinoids in a basic solution of water as the solvent and a weak alkaline additive as the solute. The systems, apparatus, and methods extract the dominant cannabinoids and their polar cannabinoid acid counterparts without the use of continuous distillation via a catalyst, and may be performed at ambient room temperature. The extracted materials and solution are then drained from the apparatus.

Abstract: A coupler for a trailer is provided for capturing a hitch ball that is affixed to a towing vehicle. The coupler includes a hemisphere cylinder pocket to receive the hitch ball and a lever to capture the hitch ball. When the hitch ball enters the pocket, it moves the lever from a release position to a captured position. In either position, a portion of the lever protrudes into the pocket. A locking pin is biased against the lever. Once moved to the captured position, an aperture on the lever aligns with the locking pin and the locking pin extends through the locking pin, locking the lever in the captured position. To release the coupler, the user pulls the locking pin clear of the lever. The locking pin can be pulled clear with a manual release handle or an electrical actuator.

Abstract: Methods and systems create a data asset generator based on a knowledge-graph-based recommendation engine to present data asset type options to a user generating a data asset. The data asset type options are contained in a template. The user is required to use the templates generated by the system when creating a data asset. The templates are based on ontologies, which are based on a knowledge graph that stores the relationships between data asset types. Data asset types correlate to data asset characteristic clusters, which are clusters of keywords from previously generated data assets. The templates may help users select relevant data asset types and ensure regulatory compliance. By requiring a user to modify or adapt the template, data assets being generated may be standardized among previously generated data assets and data assets being generated, which may reduce querying conflicts and improve the readability and interoperability of datasets.

Abstract: This invention describes a new method to generate oilseed seed. The process involves the delivery of pollen of the male parent at will, as available either in a preserved pollen bank, or using real-time collection from male plants as they become available. Desired pollen is delivered to fertile females during the period when viable pollen from the females and locally proximal unrelated plants is not being released. The delivered male pollen is in such amounts and fortuitously timed that it preferentially pollinates the females. Such fortuitous timing may involve the intentional application of pollen to females a day or two prior to female parent pollen becoming viable, and/or during several periods wherein female parent pollen and/or other proximal plant pollen is not being shed.
