  • Publication number: 20250141826
    Abstract: Proposed is a method for providing reaction contents by a server. The method may include receiving a request to post a custom content for at least one reaction content and an object related to the custom content on a first user's profile screen from a first user terminal, and in response to a request to view a first user's profile screen from a second user terminal, providing the first user's profile screen comprising the object to the second user terminal. The method may further include providing at least one reaction content for the object to the second user terminal, wherein at least one of the at least one reaction interface is based on the custom content, receiving an interaction with at least one of the at least one reaction interface from the second user terminal, and providing reaction information associated with the interaction to the first user terminal.

  • Patent number: 12043570
    Abstract: Proposed are a flexible cover window for simultaneously improving strength characteristics and folding characteristics of a glass-based ultra-thin flexible cover window, and a method of manufacturing the same. A glass-based flexible cover window is configured such that a ratio of the intensity of replacing metal ions at the glass center to the intensity of replacing metal ions at the glass surface is 1:3 or greater. The present disclosure can provide a flexible cover window with improved window strength characteristics and folding characteristics by adjusting the depth (ion penetration depth) and the surface compressive stress of a tempered layer by performing a gradient tempering process including primary tempering, slimming, and secondary tempering.

  • Publication number: 20230326316
    Abstract: Provided are a system and method for estimating a location of a forest fire. The system for estimating the location of the forest fire may include an artificial intelligence-based forest fire detection module that detects a forest fire from a captured image using an artificial intelligence model; a monitoring camera configured to monitor a predetermined area; a direction estimation module configured to estimate a direction of the forest fire on a map, using a forest fire detection image provided from the artificial intelligence-based forest fire detection module and data of the monitoring camera; and a location estimation module configured to estimate the location of the forest fire, using an altitude map table configured to provide altitude of a corresponding location from latitude and longitude of the monitoring camera, based on the estimated direction of the forest fire.

  • Publication number: 20130014877
    Abstract: Disclosed herein is a vehicle tire, which can increase fuel efficiency by improving aerodynamic performance and lowering rotation resistance of the tire, and enhances safety by allowing stable contact between the tire and a road when travelling at high speeds. To this end, the vehicle tire having a sidewall section arranged between a shoulder section connected to an edge of a tread section and a bead section to be mounted on a wheel includes a plurality of ridge-type curved protrusions embossed above a side mold base of the sidewall section and successively formed in the clockwise direction along by the sidewall section from a start point placed at one side and starting at an upper rim flange of the bead section to an end point placed at the other side on a parting bottom line placed at a top of the sidewall section.
