Abstract: A connector assembly comprises a housing assembly including a housing shell and a center pin disposed on an inner side of the housing shell, and a head assembly including a head shell detachable from the housing shell, a head body fixed to an inner side of the head shell, and a socket mounted on the head body. The socket includes at least four contact members disposed around a central axis of the head body in a circumferential direction. Each of the contact members has a shape bent toward the central axis of the head body.

Abstract: An electronic device, according to one embodiment of the present invention, can comprise: a housing which has an opening part penetrating through the inside and the outside of the electronic device and forms the outside of the electronic device; a key button inserted into the opening part so as to be movable; a sealing member which is disposed such that the sealing member slidably contacts the outer surface of the key button, and prevents communication between the inside and the outside of the electronic device through the inner surface of the opening part and the outer surface of the key button; and a push switch accommodated in the housing and pressed by an inward movement of the key button. Various other embodiments are possible.

Abstract: A data traffic control method and system is provided for controlling data transmission amount efficiently in a Long Term Evolution (LTE) system. The traffic control method of the present invention includes monitoring to detect overload of traffic by checking radio resource usage periodically; checking, when traffic overload is detected, a non-controlled packet ratio; and determining whether to control the traffic depending on the non-controlled packet ratio.

Abstract: Disclosed is a packet switch equipment and a band control method using same. In accordance with one embodiment of the invention, a number of packets are sampled by using a packet sampling function provided by a packet switch chip, and the sampled packets are transmitted to a CPU. By using the transmitted sample packets, the total amount of bandwidth used by a corresponding user is estimated based on the source MAC address or the source IP address. If the estimated value exceeds a predetermined threshold, a bandwidth limitation function is applied to the user that is providing packets that exceed the bandwidth. A number of users can be dynamically recognized even when they are undefined, and a dynamic bandwidth limitation function is performed by tracking the bandwidth used by a corresponding user.
