Abstract: A computer system includes a system unit; a communication unit which performs a wireless network communication with a base station; and a controller that controls the communication unit to transmit a communication ending message if a shutdown event of the system unit occurs, and shuts down the system unit after the completion of the transmission of the message.

Abstract: A pair of functional metal ion bands are provided. The pair of functional metal ion bands are attached to meridians and acupoints of the human body in a simple manner to induce a smooth flow of current in the body, thereby rapidly changing a disease condition to a normal state. The pair of functional metal ion bands comprise a gold-colored thin metal plate as a positive electrode and a silver-colored thin metal plate as a negative electrode wherein the gold-colored thin metal plate is composed of Cu and a metal selected from Ag, Au and Pt and the silver-colored thin metal plate is made of an alloy of Al, Si, Fe, Cu, Mn, Mg and Zn. The pair of functional metal ion bands are manufactured by processing each of the thin metal plates to have a thickness of 1 ?m to 1 cm and a diameter of 1 mm to 50 cm, and attaching the processed metal plate to one side of a soft adhesive fabric using an adhesive.

Abstract: A mobile device having a messenger function and a method for supporting such a messenger function is provided. When a messenger function is activated, the mobile device receives messenger data from a presence server. This messenger data includes state information about other mobile devices connected to the presence server. Then the mobile device classifies the received message data according to at least one criterion among a device, a time, and a modified time, and then stores it as history data. Also, at a user's request, the mobile device outputs the history data of a selected other mobile device.

Abstract: A content sharing method and system are provided such that a first client stores a content in one of its local storage and a content server and a second client requests from an information server one of a query and subscription of the content and downloads the content from the respective one of the local storage of the first client and the content server with reference to the respective one of the query and subscription result sent by the information server.

Abstract: A text-input device and method is provided.

Abstract: An apparatus and method of managing power for a mobile device is disclosed, which can prevent an inflow of overcurrent to the device when the device is charged. The apparatus includes a state judgment unit to judge whether a battery of the mobile device is being charged, a voltage level detection unit to detect a voltage level of the battery if the battery is judged as being charged, and a control unit to control a driving of the mobile device in accordance with the detected voltage level.

Abstract: The present invention relates to a security system comprising a message sending server to send a message to a user terminal having an identifier (a phone number or an e-mail address); at least one sensor to sense whether an emergency arises; and a controller that previously registers location information of each sensor therein, accesses the message sending server through Internet, and sends the identifier of the user terminal, the location information of the sensor, and emergency information to the message sending server to transmit the location information and the emergency information as the message to the user terminal when the sensor senses that the emergency arises. Thus the present invention provides a security system letting a user to know not only whether an emergency arises but also where the emergency arises.

Abstract: A remote power controller and a method of controlling the same, which can distinguish between a telephone call to speak with a person and a telephone call to enable an electronic device.

Abstract: The present invention provides a remote control system and a remote control method of an electronic appliance, capable of controlling an electronic appliance remotely by means of a user's terminal accessible to the Internet, without constructing a separate network.

Abstract: A computer having a modem outputs a telephone bell signals regardless of an active state of the computer as well as the modem. The modem provides a voltage signal responsive to the active state thereof. The computer system includes a bell signal generator for producing a bell signal in response to a ring signal received over a telephone line connected to the modem. Further, a relay switch is provided across the telephone line directed to the bell signal generator, the relay switch comprising normal-on switches allowing the telephone line to be connected to the bell signal generator when the modem is inactive state, and being activated to cut off the switch in response to the voltage signal fed from the modem. A speaker is connected to the output of the bell signal generator. If a telephone set is not connected to the modem, the computer of this invention may detect the telephone ring signal and sound a bell signal even if the computer as well as the modem is not in the active state.

Abstract: A method of controlling a computer system having an antenna capable of being drawn out and in, with which an automatic wireless network connection/disconnection can be made by drawing out/in the antenna. The present invention provides automatically wirelessly accessing and disconnecting to a computer system in one of system power states of powered, power-save and powered-off, by sensing whether the antenna is drawn out/in, and if sensed that the antenna is drawn out, converting the system into the powered state, if the system is in the state of power-save or powered-off, and executing/closing a network accessing program wirelessly accessing/disconnecting the network depending upon whether the antenna is drawn out/in, respectively.
