  • Publication number: 20240251411
    Abstract: A method and apparatus of accessing a channel in a wireless local area network is provided. A destination station receives a request to send (RTS) frame to allocate a network allocation vector from a source station over a first bandwidth and transmits a clear to send (CTS) frame over a second bandwidth to the source station in response to the RTS frame. The second bandwidth is dynamically determined when a first parameter has a predetermined value.

  • Publication number: 20240237805
    Abstract: The present invention relates to a refillable cosmetic container configured such that a refillable inner container filled on the inside with cosmetic material is removably inserted inside an outer container and can be replaced with a new container when all of the cosmetic material has been used. The inner container can be replaced after being easily removed from the outer container by switching to an unlocked state by turning a container support counterclockwise a certain angle, for example, 90°. Since the outer container can be continuously reused by discarding only the inner container having a simple structure, it is possible to decrease environmental pollution and significantly reduce the cost of manufacturing the cosmetic container.
