  • Patent number: 12218801
    Abstract: Disclosed is an adaptive deep learning inference system that adapts to changing network latency and executes deep learning model inference to ensure end-to-end data processing service latency when providing a deep learning inference service in a mobile edge computing (MEC) environment. An apparatus and method for providing a deep learning inference service performed in an MEC environment including a terminal device, a wireless access network, and an edge computing server are provided. The apparatus and method provide deep learning inference data having deterministic latency, which is fixed service latency, by adjusting service latency required to provide a deep learning inference result according to a change in latency of the wireless access network when at least one terminal device senses data and requests a deep learning inference service.

  • Publication number: 20250018344
    Abstract: The present disclosure relates to a hydrophilic modified polymer membrane and a method for fabricating the same, and more specifically, to a polymer membrane dip-coated with double bond-containing PVDF (DPVDF) and modified to be hydrophilic by reaction with a polymer or monomer containing an amine group, and a method of fabricating the same. The polymer membrane of the present disclosure is fabricated by physically coating a porous polymer substrate by dip coating with DPVDF, and then chemically modifying the surface of the dip-coated substrate to be hydrophilic using a polymer or monomer containing an amine group. That is, the polymer membrane is fabricated by performing both physical coating and chemical coating so that the dissolution of inorganic particles in the membrane can be further suppressed.

  • Publication number: 20240320075
    Abstract: A semiconductor storage device searches for an optimal read voltage on the basis of an error bit variance for each second read voltage interval without performing repeated additional reads up to the limit of left and right cell difference probabilities. Accordingly, the semiconductor storage device can detect an optimal read voltage rapidly and accurately by minimizing the number of reads for a memory cell, when performing a second read for determining the optimal read voltage.

  • Patent number: 10742355
    Abstract: An apparatus that receives a non-binary polar code through a channel includes a low-complexity decoder and a memory. The low-complexity decoder is configured to selectively calculate first common terms for input symbols in the non-binary polar code other than a first input symbol corresponding to a first target output symbol. The selective calculation uses a lower triangular kernel and log likelihood ratios of the input symbols generated based on a channel characteristic of the channel. The low-complexity decoder is also configured to calculate log likelihood ratios of the first target output symbol using the first common terms and to determine a value of the first target output symbol based on the log likelihood ratios of the first target output symbol. The memory is accessible by the low-complexity decoder and is configured to store the first common terms.
