  • Publication number: 20210315817
    Abstract: The present disclosure relates to a cannabinoid based dry or aqueous self-emulsification system for infusing a composition with a cannabinoid. The self-emulsification system comprises: a) at least one cannabinoid in a carrier oil; b) a plurality of self-emulsifiers having a targeted combined HLB value; and c) a targeted plurality of self-emulsifiers to oil ratio; wherein b) and c) operate to solubilize at least 1 mg of the cannabinoid in 1 mL of the composition. The dry self-emulsification system is in the form of a self-emulsifiable solid which spontaneously forms an emulsion after the addition of an aqueous medium, whereas the composition spontaneously forms an emulsion upon dilution of the aqueous self-emulsification system with water.

  • Publication number: 20210315249
    Abstract: The present disclosure relates to a Cannabis-infused product comprising a cannabinoid profile including one or more cannabinoid, a first composition for controlling onset of the cannabinoid profile and a second composition for controlling offset of the cannabinoid profile in a subject having used the Cannabis-infused product, wherein the second composition has a delayed onset compared to that one of the first composition. The present disclosure also relates to methods of manufacture and of using same.

  • Publication number: 20210315818
    Abstract: The present disclosure relates to a cannabinoid based emulsification system for infusing a non-aqueous composition with a cannabinoid, the emulsification system comprising: a) at least one cannabinoid in a carrier oil; b) a plurality of emulsifiers having a targeted combined HLB value; and c) a targeted plurality of emulsifiers to oil ratio; wherein b) and c) so that at least 10 wt % of the cannabinoid is solubilized in the oral cavity within 30 minutes after a subject consumes the non-aqueous composition, based on the total weight of the cannabinoid in the non-aqueous composition. Methods of making and using such emulsification systems, and cannabinoid concentrate compositions and cannabis infused non-aqueous compositions comprising such emulsification systems to form beverages, human and pet edibles and confectionaries are also encompassed by the present disclosure.

  • Publication number: 20210298340
    Abstract: The present disclosure relates to a cannabis-infused product comprising a cannabinoid profile including one or more cannabinoid, a first composition for controlling onset of the cannabinoid profile and a second composition for extending offset of the cannabinoid profile in a subject having used the cannabis-infused product, wherein the second composition has a delayed onset compared to that one of the first composition. The present disclosure also relates to methods of manufacture and of using same.

  • Patent number: 6577992
    Abstract: Methods and apparatus for generating a hierarchical representation of a circuit include obtaining a netlist corresponding to the circuit, the circuit including a plurality of subcircuits. A hierarchical representation of the circuit is then generated from the netlist, the hierarchical representation including the plurality of subcircuits arranged among a plurality of levels of the hierarchical representation. Each one of the plurality of subcircuits has an associated subcircuit definition. In addition, each of a plurality of subsets of the subcircuits share a same subcircuit definition, where memory storage for the same subcircuit definition is shared by the subcircuits in each of the subsets. Moreover, each one of the plurality of subcircuits has a dynamic voltage state.
