Title: Apparatus and Method for System Monitor in Switching System
Inventor: LEE UI CHEON
IPC: H04M3/22
Filed: 2000-12-28
Abstract: PURPOSE: A system state supervising apparatus in an exchange system is provided to transmit system information showing the state of system during the management of the exchange system to the terminal of manager by wireless, thereby supervising the state of the exchange system irrespective of time and place. CONSTITUTION: A message detecting unit(31) detects a system message showing an operation situation of the exchange system(30) and then outputs the detected message to a message output unit(32). The message output unit(32) outputs the detected message to a message output device(40) of a maintenance system and a wireless transmission discrimination/information conversion unit(33). The conversion unit(33) receives a system message from the message output unit(32) and discriminates the existence of wireless transmission of the system message. If the system message must be transmitted by wireless, the conversion unit(33) converts the system message into character information and applies the information to a wireless transmission unit(34). Thereafter, the wireless transmission unit(34) transmits the character information to a mobile terminal(50) such as a cellular phone or a PCS(Personal Communication System).

By adding charcoal powder to the resin hairs(3), the flexibility of the resin hairs(3) is improved, thereby preventing an object to be cleaned from being damaged. In addition, impurities sticking to the cleaning brush(1) are purified by charcoal powder added to the resin hairs(3).

Title: Video apparatus with auto security and control method of the same
Inventor: OH WAN SEOK
IPC: H04N21/4415
Filed: 2001-03-07
Abstract: PURPOSE: An image display system having an automatic security function and a method of controlling the system are provided to prevent personal information of a user from leaking only with simple setting without an additional operation of the user. CONSTITUTION: An image display system having an automatic security function includes a key input unit(18), a security function processor(16), and a microcomputer(17). The key input unit is used for inputting commands for operating security function, functions related with security and the image display system. The security function processor monitors authenticity of a user, existence of an authenticated user or non-authenticated user and outputs an image output stopping command or an alarm message output command according to the monitored result. The microcomputer operates the security function processor and controls the image display system to carry out the command output from the security function processor.

Title: Microscope Apparatus and Inspection Method for Semiconductor Wafer Inspection
Inventor: KIM GYEONG DAE
IPC: H01L21/66
Filed: 2001-03-19
Abstract: PURPOSE: A microscope for testing a semiconductor wafer and a test method using the same are provided to test all sides of a wafer by transferring a sample plate to an X-axis, a Y-axis, and a Z-axis and tilting the sample plate as much as a predetermined angle. CONSTITUTION: An optic system(110) is used for magnifying a wafer(W) by using an object lens(111) and an eye lens(113). A display portion(120) is used for magnifying and projecting an image of the wafer(W) magnified by the optic system(110). The wafer(W) is loaded and fixed on a sample plate(130). A sample plate moving portion(200) is formed with an X, Y, and Z-axis transfer portion(210) and a tilting portion(230). The X, Y, and Z-axis transfer portion(210) is used for transferring the sample plate(130) toward an X-axis, a Y-axis, and a Z-axis. The tilting portion(230) is used for tilting the sample plate(130) to a predetermined angle. A rotation portion(180) is used for rotating the wafer(W) loaded on the sample plate(130) to a predetermined direction. A control portion(170) is used for controlling the sample plate moving portion(200) and the rotation portion(180).
