  • Patent number: 12099423
    Abstract: An electronic device is provided. The electronic device includes a connector including one or more signal terminals and a control circuit electrically connected with the one or more signal terminals. The control circuit may be configured to monitor attachment with an external device through an identification terminal among the one or more signal terminals, identify whether a designated number of, or more, monitoring signals related to attachment with the external device are detected during a designated time, and identify whether there is the attachment with the external device, based on a voltage of a power terminal among the one or more signal terminals, in response to the detection of the monitoring signals being identified.

  • Publication number: 20220346481
    Abstract: A head mold for a wig may include a head mold body and an information pattern. The head mold body may be formed using a stack type three-dimensional (3D) printer into which head information of a user may be inputted. The information pattern may be provided to the head mold body to indicate information of the wig. The head mold may be manufactured using the stack type 3D printer to prevent a generation of dusts during manufacturing the head mold. Further, the stack type 3D printer may have a low price compared to a milling machine to reduce an initial investment cost for manufacturing the head mold.
