  • Publication number: 20240104164
    Abstract: Numerous examples are disclosed of verification circuitry and associated methods in an artificial neural network. In one example, a system comprises a vector-by-matrix multiplication array comprising a plurality of non-volatile memory cells arranged in rows and columns, the non-volatile memory cells respectively capable of storing one of N possible levels corresponding to one of N possible currents, and a plurality of output blocks to receive current from respective columns of the vector-by-matrix multiplication array and generate voltages during a verify operation of the vector-by-matrix multiplication and generate digital outputs during a read operation of the vector-by-matrix multiplication.

  • Publication number: 20240033702
    Abstract: Use of biodegradable microcapsules comprising a wall made of poly(beta-amino)ester, abbreviated to PBAE, which contains an active substance. These microcapsules may be obtained by a method of interfacial polymerization between an amine monomer and a multi-acrylate monomer. Depending on the intended use, microcapsules with a wall that is weak, breakable or unbreakable and porous or non-porous are used; these properties may be obtained by the choice of the monomers and the thickness of the wall. For certain uses, it is possible to use the polymerization reaction mixture directly, without washing.

  • Publication number: 20240016751
    Abstract: Method for manufacturing microcapsules comprising a wall made of polymer material containing an active substance, comprising the following steps: —preparing an oil phase comprising a poly(beta-aminoester) prepolymer, and an active substance constituting the phase to be encapsulated; preparing an aqueous phase comprising at least one surfactant; preparing an O/W (oil in water) emulsion by adding the oil phase to the aqueous phase; and initiating radical polymerisation with in the emulsion. A polymerisation initiator must be present in the aqueous and/or oil phase.

  • Patent number: 11654410
    Abstract: A method for manufacturing microcapsules containing an active substance, the method including: providing an aqueous solution of a surfactant, an oily phase comprising the active substance and a first monomer, and a polar phase comprising a second monomer; preparing an oil-in-water emulsion by adding the oily phase to the aqueous solution of the surfactant; adding the polar phase to the oil-in-water emulsion, in order to obtain a polymer in a reaction mixture, by polymerization of the first monomer and the second monomer; isolating the microcapsules, including a wall formed by the polymer and containing the active substance, from the reaction mixture; wherein the polymer is a poly(beta-amino ester). Microcapsules obtained by the method.
