  • Patent number: 12226205
    Abstract: The present disclosure relates to a continuous glucose monitoring device, in which a body attachment unit is manufactured so as to be assembled in an applicator, thereby minimizing additional work for a user in attaching the body attachment unit to a body, and allowing attachment of the body attachment unit to the body simply by operation of the applicator. In particular, a wireless communication chip is provided in the body attachment unit to enable communication with an external terminal, thereby enabling simple and convenient use without additional work of connecting a separate transmitter, and allowing easier maintenance. In addition, the continuous glucose monitoring device is activated by a user's operation after the body attachment unit is attached to the body, such that an activation start time can be adjusted to a time appropriate to the user's needs, and the continuous glucose monitoring device can be activated in a stabilized state, and thereby can monitor blood glucose more accurately.

  • Publication number: 20250039125
    Abstract: Embodiments of the present disclosure include techniques for discovering services across networks based on a multicast domain name system (mDNS) protocol. An mDNS request for available services in a network is received from a client device. The client device belongs to a particular layer 2 (L2) domain. In response to receiving the mDNS request, a storage of the network device configured to store service records is queried to determine a set of available services. The set of available services is provided in a L2 domain different from the particular L2 domain. A response that includes the set of available services is generated. The response is sent to the client device.

  • Publication number: 20250016391
    Abstract: The present disclosure provides a method and a device for synchronization between a video frame and an audio frame on the basis of high-speed transmission of a VoD content. A content delivery server includes a transceiver and a processors. The transceiver receives, from a content requesting terminal, a search request for a specific playback time within a VOD content. In response to the search request, the processor deletes one or more audio frames existing between a video frame that corresponds to the requested playback time and an audio frame that corresponds to the requested playback time; and generates content data reconstructed to include all or part of frames existing in a period of time from the video frame that corresponds to the requested playback time to the audio frame that corresponds to the requested playback time. The transceiver transmits the reconstructed content data to the content-requesting terminal.
