Filed: 2000-07-07
Abstract: PURPOSE: A color splitter for a single-plate type LCD(Liquid Crystal Display) projector is provided to enhance light efficiency of an LCD projector by transmitting color beam through a color plate having plural color areas sequentially without beam loss. CONSTITUTION: A color splitter(72) includes a color plate(86) having plural color areas forming a flat surface, a guide shaft(82) for guiding the rectilinear motion of the color plate, and a driving motor for rectilinear moving the color plate. The driving motor is used with a linear motor or a cam motor(88) having a cam(88B) at the tip of a shaft(88A). If the cam motor is used, a spring is mounted on the same side or opposite to the cam motor to restore the color plate driven by the cam motor.

Abstract: PURPOSE: A hand-off method for an ATM(Asynchronous Transfer Mode)-based CDMA(Code Division Multiple Access) mobile communication is provided to quickly perform a hand-off by setting an ATM virtual path in parallel in a source BSC(Base Station Controller) and a target BSC. CONSTITUTION: A source BSC transmits an ATM resource assignment request message to an NMP(Network Management Processor) for assigning and managing ATM resources necessary for setting a virtual path between the source BSC and a target BSC(S11). The source BSC requests a hand-off to the target BSCs(S12).
