Abstract:
표준 충전기/어댑터 컨버터를 개시한다. 표준 충전기/어댑터 컨버터는 본체와, 본체의 일측에 결합되고, 교류를 직류로 변환하여 출력하는 표준 충전기의 플러그가 삽입 가능한 형태로 구성된 표준 충전기 소켓과, 본체의 타측에 결합되고, 충전식 휴대기기의 전원소켓에 삽입 가능한 형태로 구성된 휴대기기 연결용 플러그와, 본체 내부에 장착되고, 표준 충전기 소켓을 통해 연결된 표준 충전기가 급속 충전모드로 유지되도록 홀딩하는 충전모드 홀딩 회로부와, 본체 내부에 장착되고, 충전모드 홀딩 회로부를 통해 제공된 충전전원을 휴대기기 연결 소켓에 연결되는 휴대기기에서 필요한 정전압 직류전원으로 변환 출력하기 위한 전원변환 회로부를 포함한다. 따라서 본 발명은 국내의 TTA 표준을 강화하고, 소비자들이 보다 편리하게 장치를 충전할 수 있도록 한다.
Abstract:
A pencil case having a bookrest for a desk is provided to utilize the space of an upper plate of the desk by integrally installing the case on the upper plate of the desk and to keep writing materials while reading a book. A receiving body(10) is detachably installed in a mounting groove(104) formed on an upper plate(102) of a desk to be on a horizontal plane with the upper plate and provided with receiving spaces(11) divided into plural parts by wall bodies(41,42) to receive and keep writing materials. A support plate body(20) is composed of an inclined surface(12a) formed on a rear wall part of the receiving body and a book support part(30) integrally installed in the front side, movably supported in the body adjacent to the rear wall part having the inclined surface to open and close the receiving spaces, and supported to the inclined surface of the rear wall part in the receiving body after being opened from the body and inclined at the predetermined angle. Plural support units(40) are integrally protruded from the inner bottom part of the receiving body with facing a lower end of the support plate body, to obliquely set up the support plate body from the receiving body by supporting the book support part and the receiving body. A moving unit is installed at a part where the body and the support plate body propped up by the support units are combined, to movably hold the support plate body from the body.
Abstract:
PURPOSE: A system for recognition and monitoring of freight shipping using an RFID and an RF(Radio Frequency) transceiver is provided to facilitate a shipping operation of freight by automatically recognizing shipping positions. CONSTITUTION: An RFID(60) stores unique IDs of freight and provides the stored information when requested. The RFID performs reading and writing operations to store newly received shipping position information. An RF transceiver(40) requests unique ID of freight and automatically provides position information according to the received unique ID of freight. A shipping position information provider(30) performs signal processing and generates control signals.
