  • Patent number: 9940818
    Abstract: The present invention relates to a method for controlling a mobile phone loss prevention function by means of Bluetooth earphones. The method includes: a link loss determination step (S10) of measuring a sensitivity of a signal transmitted/received between a mobile phone and the Bluetooth earphone and determining occurrence of a link loss; warning sound generation steps (S20, S40, and S60) of, when the link loss has occurred, generating a warning sound, which warns of loss of the mobile phone, through the Bluetooth earphone in such a manner as to amplify a volume of the warning sound from a low volume to a high volume for each step; and warning sound stop identification steps (S30, S50, and S70) of determining whether a warning sound stop button has been operated by a user who has recognized the warning sound and selecting whether the generation of the warning sound is to be stopped.

  • Publication number: 20140192029
    Abstract: A touch pen includes a hollow pen body (110), a connector cap (150), of which one end is coupled to an end of the pen body (110), a cover cap (114) coupled to the other end of the connector cap (150), and a gender unit (130) including a first connector (131) at one end and a second connector (132) at the other end. The first connector (131) protrudes to the cover cap (114) side, and is fixedly accommodated by being embedded in the connector cap (150). The second connector (132) is connected to a flexible cable (133) extending from the connector cap (150) and accommodated in the pen body (110). In addition, the first connector (131) of the gender unit (130) forms a standard USB, and the second connector (132) connected with the flexible cable (133) at the other end of the gender unit (130) forms a micro USB.

  • Patent number: 5400388
    Abstract: A circuit for preventing a radio telephone engaged in a call from being cut off when a power failure occurs, wherein the radio telephone is branched with a wire telephone by a telephone line. When the power is off while engaged in a call, the telephone line is held on by a state of a line voltage and a music on hold is generated. If power turns on again in a holding state, a power off cancel data is transmitted to a portable device. If a response data from the portable device is received, the holding state of the telephone line is canceled and the music on hold is stopped, and the call through the radio telephone is connected again. If the power is not on again or if the response data is not received, it is checked during a given time whether the wire telephone is hooked off or not. If the wire telephone is hooked off or if the given time has passed, the holding state of the telephone line is canceled and the music on hold is stopped.
