  • Publication number: 20230137520
    Abstract: The present disclosure relates to a slurry composition for a secondary battery electrode, and a secondary battery electrode manufactured using same. The slurry composition includes a conductive material including a linear carbon material and a point-type carbon material, a dispersant, and an organic solvent. By adjusting the average size and content of the conductive material in the slurry such that two peaks within a specific range appear in a particle size analysis, the solubility and dispersibility of the carbon-based conductive material are improved, and thus the electrical properties of the electrode are remarkably improved.

  • Publication number: 20230139306
    Abstract: The present disclosure relates to a slurry composition for a secondary battery electrode, and a secondary battery electrode manufactured using the same. The slurry composition includes dispersants of specific components, a carbon-based conductive material, and an organic solvent. The slurry composition has an advantage in that the stability of the carbon-based conductive material is excellent. In addition, due to the presence of a polar functional group in the dispersant, the surface treatment effect for the carbon-based conductive material is excellent, and thus the dispersibility of the carbon-based conductive material is remarkably improved.

  • Patent number: 9128641
    Abstract: The present invention discloses a parameter setting apparatus and method for AUTOSAR-based software, which may lead a user to set parameters at suitable times depending on the variant attributes of parameters. In the parameter setting method, a selection of a variant attribute of a parameter of a metamodel defined to design AUTOSAR-based software is received from a user. If the variant attribute selected by the user corresponds to a variant-pre-compile attribute, setting of only a parameter having the variant-pre-compile attribute is allowed. If the variant attribute selected by the user corresponds to a variant-link attribute, setting of only a parameter having either one of the variant-pre-compile attribute and the variant-link attribute is allowed. If the variant attribute selected by the user corresponds to a variant-post-build attribute, setting of only a parameter having any one of the variant-pre-compile attribute, the variant-link attribute, and the variant-post-build attribute is allowed.

  • Patent number: 9118568
    Abstract: The present invention relates to a automotive partial networking apparatus and method, which operate or terminate only a specific electronic control unit corresponding to a service currently being provided in a vehicle network composed of a plurality of electronic control units. In the automotive partial networking method, a automotive partial networking apparatus receives a partial networking-only Controller Area Network (CAN) frame from outside of the apparatus. A partial network table is searched based on the CAN frame, and then a CAN identification (ID) is searched for. A partial networking-only CAN frame is generated using the CAN ID. Partial networking is performed by transferring the generated partial networking-only CAN frame to at least one electronic control unit corresponding to a vehicle service.

  • Publication number: 20150229485
    Abstract: The present invention relates to a method and an apparatus for performing multicast communication in an ID/locator separation environment. The method includes: receiving a packet; determining whether an entry corresponding to a destination ID included in a packet header of the packet is in a forwarding table; forwarding the packet based on a next hop address included in the entry, if the entry corresponding to the destination ID is present. The entry corresponding to the destination ID can include a plurality of next hop addresses if the destination ID is an ID for a multicast group domain, and the step of forwarding the packet can be carried out by copying the packet by as many as the number of next hop addresses and sending the copied packet to each of the next hop addresses.

  • Patent number: 8789009
    Abstract: Provided are an EMF model synchronization method and system. The system calculates a weight based on a hierarchy for an object identifier in a changed model, when the change of the model occurs in an EMF model which has an XML element path as an attribute. The system accumulates the calculated weight to a sum of weights. When the sum of weights becomes greater than the threshold value, the system simultaneously updates all models which are changed until the sum of weights becomes greater than the threshold value, thereby synchronizing change contents. As a hierarchy of an identifier changed on an XML path becomes higher, the weight is determined to have a larger value.
