Abstract:
Disclosed is a method for operating a wavelength-division-multiplexed passive optical network (WDM-PON) including an optical line terminal (OLT) and a plurality of optical network units (ONUs), each of which is connected to the OLT and communicates with the OLT. The method comprises the steps of transmitting a first control channel including allocation information of downstream data channels and allocation information of time slots for the downstream data channels to each of the plurality of ONUs; and transmitting downstream data to the plurality of ONUs using their associated downstream data channels, each having at least one time slot, based on the information included in the first control channel.

Abstract:
PURPOSE: An apparatus and method for using a rotary key in a mobile terminal are provided to allow a user to quickly select and check a menu and operation mode function through a rotary key unit even when a mobile terminal is in a closed state. CONSTITUTION: A folder opening/closing sensor senses whether a folder of a mobile terminal is opened or closed and outputs a sensed signal to a controller(301). If the folder is in a closed state(302), the controller converts the mobile terminal to the second mode(303). If a user rotates a rotary key unit(304), the controller displays an operation of the rotary key unit through the second display unit(305). If the mobile terminal is in an opened state(306), the controller converts the mobile terminal to the first mode(307). If the user rotates the rotary key unit(308), the controller displays an operation of the rotary key unit through the first display unit(309).
Abstract:
PURPOSE: A signal relay apparatus is provided to replace an inferior mass flow controller by another mass flow controller different in specification, thereby reducing costs for having a mass flow controller in reserve. CONSTITUTION: A housing(102) having a predetermined space inside is provided. A plurality of first connector input terminals(104a) are installed to be continued from an outer surface of the housing to an inner surface, and are electrically connected with connectors of first equipment different in shape. A plurality of second connector input terminals(104b) are installed to be continued from the outer surface of the housing to the inner surface, and are electrically connected with connectors of second equipment electrically connected with the first equipment and different in shape. A plurality of connection lines electrically connect signal pins transmitting common signals in the first and second connector input terminals.
Abstract:
PURPOSE: An antenna apparatus of a folder type cellular phone is provided to carry with one easily, prevent from breaking and secure a fully separated distance between a main antenna apparatus and a diversity antenna. CONSTITUTION: The first antenna(2) outputs a reception signal received from a base station to a transceiving unit(10) through a duplex(8) and transmits a transmission signal outputted from the transceiving unit(10) through the duplex(8) to the base station. The first antenna(2) is operated not only at a call waiting state, i.e., when a folder of a cellular phone is closed, but also at a call state. The second antenna(4) performs the same function of the first antenna(2). Since the second antenna(4) is connected to the first antenna(2) by a connection unit(6) only when the folder of the cellular phone is opened, it does not operate when the folder of the cellular is closed.

본 발명은 마이크로프로세서를 이용한 전자회로의 가변 주소할당장치 및 방법에 관한 것으로서, 가변 주소할당 장치는 할당하고자 하는 주소의 최상위값을 소프트웨어적으로 저장하는 제1레지스터; 할당하고자 하는 주소의 최하위값을 소프트웨어적으로 저장하는 제2레지스터; 입력되는 주소와 제1레지스터에 저장된 값과 비교하는 제1비교기; 입력되는 주소와 제2레지스터에 저장된 값과 비교하는 제2비교기; 및 제1비교기 및 제2비교기에서의 비교결과 입력되는 주소가 제1레지스터의 최상위 값과 제2레지스터의 최하위값 사이에 존재하면 해당 칩선택신호를 발생하는 칩 선택신호 발생부를 포함한다. 본 발명에 의하면, 주소할당과 무관하에 전자회로를 설계할 수 있고, 주소할당 변경이 발생한 경우, 하드웨어의 재구성 없이 소프트웨어적으로 주소를 재 할당하는 효과가 있다.
