Abstract: PURPOSE: An apparatus for recognizing characters in a cellular phone is provided to pattern a movement signal of a user when the user starts writing with a handset and to compare the patterned movement signal with a prestored pattern to select a predetermined character or a macro pattern, so that the user can quickly input characters. CONSTITUTION: A character inputting sensor(240) detects a user's movement signals consecutively changed according to the user's writing, and outputs the detected signals to a controller(210). A character reader(250) patterns the signals from the controller, and compares the patterned signals with prestored character patterns to select predetermined characters, then outputs the selected characters to the controller. The controller activates the character reader according to switching operations of a character reading mode converting switch. A storage(230) stores character data corresponding to the selected characters under control of the controller. A displayer(220) outputs the selected characters on a screen. A signal transmitter(260) converts the character data into signals appropriate for signal transmissions, and outputs the signals.

Abstract: PURPOSE: DDR(Double Data Rate) data is provided which output synchronized with a certain clock in a DDR SDRAM(Synchronous Dynamic Random Access Memory) regardless of output loading. CONSTITUTION: The calibrated DLL(Delay Locked Loop) apparatus(40) synchronizes its output data signal with an input clock signal. A delay circuit(52) generates a clock output signal having a selective delay after receiving the input clock signal. After receiving the clock output signal, a gating circuit(60) creates an imitation data signal corresponding to the clock output signal and latches an input data signal in response to the clock signal for generating the output data signal, further responding to a switching control signal with a first logic value for having the output data signal only supplied to the output and a switching control signal with a second logic value for having the imitation data signal only supplied to the output. A driver(54) supplies the output signal of the gating circuit to the output as the output data signal of the circuit(40). A phase comparator(58) forming a feedback loop from the driver compare the input clock signal with the imitation data signal appearing at the output of the driver. The delay circuit responds to the switching control signal with the second logic value which enables the imitation data signal to be selectively synchronized with the input clock signal. The switching control signal with the first logic value disables the phase comparator and the delay circuit maintains its latest delay value.

Abstract: PURPOSE: A method for initializing an automatic set is provided to sense a screen blanking before the screen blanking is generated, which is caused by peripheral unfavorable conditions, and to automatically turn on/off power, thereby preventing screen damage and increasing product reliability. CONSTITUTION: If a standby power is supplied, an automatic start(AST) bit of a micro processor is set up as '1', and power is turned on. A TV system confirms a black current feedback(BCF) bit for displaying screen stability and instability, after standing by for a predetermined time. The TV system waits until the BCF bit becomes '0' which represents a stable state of a screen. If the BCF bit becomes '0', the TV system sets up the AST bit as '0', and performs a normal operation of the screen. The TV system checks the BCF bit, to prevent a screen blanking from being generated, which is caused by unfavorable conditions while the screen is normally operated. If the BCF bit is changed into an unstable state '1' from the stable state '0', the TV system turns off the power and resets a system to an initial state.
