Abstract:
The present invention relates to an electronic device, and to a method for controlling a connection between an electronic device and a charging device, and a device for providing the same. To this end, the charging device of the present invention can comprise: a housing, which includes a first surface facing a first direction and a second surface facing a second direction different from the first direction, and is configured such that at least a part of the first surface comes in contact with a surface of a first electronic device; an electric conductive coil located within the housing so as to be closer to the first surface than the second surface; a wireless charging unit receiving power from an external power source, and including a charging circuit for wirelessly providing the power, having passed through the coil, to the first electronic device through the first surface; an electric connection unit exposed to the housing; a communication unit including a wireless communication circuit for supporting wireless communication with the first electronic device and allowing the wireless communication to have a predefined frequency range, and a wired communication circuit for receiving data from the first electronic device by using the wireless communication circuit, and transmitting the data to at least one second electronic device through the connection unit; and a processor for controlling, overall, an operation of the charging device in order to wirelessly charge the first electronic device.
Abstract:
A method and electronic device for performing wireless charging are provided. The electronic device includes a housing, a conductive coil, a power transmission circuit electrically connected to the conductive coil, and configured to wirelessly transmit power to an outside of the housing through the conductive coil, a voltage source electrically connected to the power transmission circuit, and a control circuit electrically connected between the power transmission circuit and the voltage source. The control circuit is configured to change power radiated through the conductive coil, monitor a frequency of a signal and/or electromagnetic waves radiated through the conductive coil, and adjust a level of a voltage from the voltage source based on at least a part of a monitored result of the frequency.
Abstract:
Disclosed is an electronic device including a display; a connector; and a processor configured to sense moisture introduced into the connector in a state where one or more functions executable by connection of the connector with an external electronic device are activated; deactivate the one or more functions based on the sensing; determine whether the introduced moisture is removed in a state where the one or more functions are deactivated; and activate the one or more functions if the moisture is removed.
Abstract:
A cordless charging apparatus includes a housing, a main substrate accommodated in the housing, a coil unit stacked on the main substrate, and a connection member for electrically connecting the coil unit to the main substrate. The connection member includes a connector provided on the main substrate, and a connection substrate provided at the coil unit in order to contact the connector and electrically connect with the coil unit stacked on the main substrate.
Abstract:
An E-mail client establishes a connection to an E-mail server to provide a Direct Push E-mail service by sending to the E-mail server a request message periodically to check whether an E-mail has arrived at the E-mail server and a connection item in a header of the request message, which is set as a closed state, and disconnects the connection upon receiving a response message to the command from the E-mail server. The E-mail server establishes a connection to the E-mail client to provide the Direct Push E-mail service by receiving the request message from the E-mail client, sending a response message to the command to the E-mail client, determining a connection item in a header of the request message, and disconnecting the connection if the connection item is set as a closed state.
