  • BIODEGRADABLE POLYMER FINE PARTICLE FOR FILLER, FREEZE-DRIED BODY INCLUDING THE SAME, MANUFACTURING METHOD THEREOF, AND FILLER INJECTION INCLUDING FREEZE-DRIED BODY
    Publication number: 20240157025
    Abstract: Disclosed herein are a biodegradable polymer microparticle for a filler, a freeze-dried body including the same, a manufacturing method thereof, and filler injection including the freeze-dried body. The freeze-dried body includes hydrophilic surface-treated biodegradable polymer microparticle and a biocompatible carrier, wherein the hydrophilic surface-treated biodegradable polymer microparticle has an average particle diameter (D50) of 20 to 50 ?m and is polydioxanone which has a carboxyl group on the surface thereof. The hydrophilic surface-treated biodegradable polymer microparticle is a plasma surface-treated product or a base surface-treated product using discharge of the biodegradable polymer microparticle. The content of the biocompatible carrier is 1 to 5 parts by weight based on 100 parts by weight of the freeze-dried body.

  • Patching boot data utilizing one-time programmable memory and copy patch code instructions
    Patent number: 10459715
    Abstract: A semiconductor system comprises a nonvolatile memory storing a patch code, the patch code comprising a unique identifier (ID). An internal read only memory (IROM) stores a boot code, the boot code comprising a patch code execution function for executing the patch code and a linked register (LR) address for specifying a storage location where the patch code is to be executed. A static random access memory (SRAM) stores a copy of the patch code at the storage location, the copy of the patch code including the unique ID. A processor executes the copy of the patch code from the storage location. The processor executes the copy of the patch code stored at the storage location in the SRAM according to the comparison result.
