Abstract:
본 발명의 일 실시예는, IP 패킷을 받을 때마다 IP 패킷의 페이로드를 저장해 두었다가 TCP에 의해 재전송된 재전송 패킷을 받았을 때 기존에 저장해 둔 페이로드와 재전송 패킷의 페이로드를 비교하여 공격 패킷을 구분함으로써, 공격자가 재전송 패킷의 페이로드에 공격 패킷을 집어넣어 전송함에 의해 이동통신망을 경유하여 전송되는 데이터를 무료로 사용하고자 하는 악의적인 공격을 막을 수 있는 데이터 과금시스템에 관한 것이다.
Abstract:
A quasi-active micromixer having a rotor installed in a microchannel is provided to accelerate mixing of different fluids flowing in the microchannel effectively by installing a flow disturbing unit operated only by energy of the flow of the fluid in the microchannel. A quasi-active micromixer having a rotor installed in a microchannel(30) by MEMS(Micron Electro Mechanical Systems) is composed of the microchannel; inflow ports(40,50) and an outflow port(60) formed at both ends of the microchannel, respectively; and a flow disturbing unit(20) having plural rotors arranged in the middle of the microchannel and operated by the flow of fluid flowing in the microchannel. A spacing unit is formed in the microchannel to prevent the lower part of a rotor blade from coming into contact with the microchannel.

Abstract:
PURPOSE: A three dimensional package of an ultra-thin MEMS chip and an IC chip are provided to connect conductive via and the conductive material formed on each via by manufacturing the thickness of a single chip to be thin. CONSTITUTION: A three dimensional package of a thin IC chip and MEMS chip includes at least two thin IC hip and MEMS chip. At least, two thin film integrated circuit chips are perpendicularly laminated. The thin film MEMS chip is laminated on one among thin film integrated circuit chips. A circuit is formed on the thin film integrated circuit chips. A conductive via passing through the thin film is formed to transmit a signal and power between IC chips or the thin film MEMS chip. The conductive material is used in order to interlink the conductive via and the circuit or the MEMS chip.
