A connector may include a plurality of contacts electrically connected to a mating connector and separated from one another. At least one of the contacts may include a magnet, and a conductive housing for surrounding at least one side of the magnet.

Electric connector

An electronic device and method and power supply are disclosed. The electronic device includes comprising a connector for electrically coupling with an external power supply unit, and a processor. The processor implements the method, which includes detecting a connection state with the external power supply unit, and detecting whether power supplied from the external power supply unit is abnormal, and controlling the power when the power supplied has an abnormal value. The power supply may include a connector for electrically coupling with an electronic device, and a processor for detecting a connection state with the electronic device, detecting whether power supplied to the electronic device by the power supply unit has an abnormal value, and controlling the supplied power when the power is abnormal.

Method for controlling power of electronic device and electronic device thereof

An electronic device and method for transmitting information on a barcode by using an infrared Light Emitting Diode (LED) are provided. The method includes transforming a displayed barcode into a binary code, and lighting ON/OFF an infrared LED according to set order based on the binary code.

A printed circuit board (PCB) for mounting a dielectric radio frequency (RF) band pass filter (BPF) thereon, and a method of making the same, is provided. The filter has an input terminal, an output terminal, and a ground terminal including a first, a second, and a third terminal. The PCB includes a first terminal for mounting the input terminal of the RF BPF thereon. A second terminal of the PCB is for mounting the output terminal of the RF BPF thereon. The second terminal is disposed horizontally apart from said first terminal by a predetermined distance. A third terminal of the PCB is for mounting the first terminal of the ground terminal of the RF BPF thereon. The third terminal is disposed between said first and said second terminals. A fourth terminal of the PCB is for mounting the second terminal of the ground terminal of the RF BPF thereon. The fourth terminal is disposed vertically apart from said first terminal by a predetermined distance. A fifth terminal is for mounting the third terminal of the ground terminal of the RF BPF thereon. The fifth terminal is disposed vertically apart from said second terminal by a predetermined distance. First to fourth holes are formed in a PCB thickness direction between the first and third terminals, between the second and third terminals, between the first and fourth terminals, and between the second and fifth terminals.

An intercommunication method between portable units in a TDMA (Time Division Multiple Access) cordless telephone system. In an embodiment of the present invention, it is determined whether a portable unit is positioned in the propagation area of a base unit upon an intercom request from the portable unit. A time reversal is then performed when the portable unit is out of the propagation area of the base unit. Time slots are designated for intercommunication between the portable unit and a portable unit to be called and an intercom call signal is transmitted in the designated time slots. When a called party responds to the intercom call signal, a speech mode is performed. Upon termination of the intercom call, the reversed time is reversed again to recover the original state. In another embodiment, it is determined whether a portable unit is positioned in the propagation area of a base unit upon an intercom request from the portable unit. Time slots are designated for intercommunication between the portable unit and a portable unit to be called when the portable unit is out of the propagation area of the base unit, and an intercom call signal is transmitted in the designated time slots. When a called party responds to the intercom call signal, the speech mode is performed.
