Title: Device and method for distinguishing multiple broadcasting standard
Inventor: HWANG IN JUN
IPC: H04N7/08
Filed: 1998-11-13
Abstract: PURPOSE: A device is provided to distinguish the multiple broadcasting standard of a color television by using color burst signal frequency decided digitally at a high speed. CONSTITUTION: A device for distinguishing a multiple broadcasting standard, comprises an analog and digital converter(ADC)(10), a multiplication unit(12), a low pass filter(LPF)(14), a unit for calculating difference of frequency(16), a distinguishing signal detector(18), a frequency track unit(22) composing a self radiator(20), and an oscillation signal generator(24). The self radiator generates a first and a second self oscillation signal(O1,O2) having an independent oscillation frequency, and supplies the signals to the multiplication unit. The frequency track unit tracks fc by fa' until fa' is converted to fa. Also the frequency track unit decides if the converted fa' is correctly pursued to the frequency(fc) of the color burst signal for 2 hours. Then finally fa' is converted fc if the converted fa' is not pursued. Therefore, the device detects the frequency of the color burst signal unrelated how much the frequency(fc) is in the initial state.

Title: Air conditioner using thermoelectric semiconductor
Inventor: LEE JAE HUI
IPC: F24F1/02
Filed: 1998-12-30
Abstract: PURPOSE: An air conditioner using a thermoelectric semiconductor is provided to have no noise and vibration and have a simple structure by embedding one end of a cooling pipe in a heat emitting plate. CONSTITUTION: Indoor temperature continually falls down with continual current supply to a heat conductive semiconductor(11). A temperature sensor(14) measures temperature of air sucked into an indoor suction hole(10a). When the temperature is less than the temperature set by an operating unit(19), a first and a second motor(22) stops to operate. Thus, even if an air conditioner continually operates, the indoor temperature is kept in a regular temperature. A cooling pipe(21) cools heat from a heat emitting plate(12). In the cooling pipe, cooling water circulates in a zigzag course.

Abstract: PURPOSE: A system for managing the power of an optic transceiver is provided to control the power status of an optic transceiver suitably. CONSTITUTION: A base station operator instructs a power status measurement command message for a specific remote optic transceiver to a radio frequency controller(S200). The radio frequency controller confirms whether an ROPA(Remote Optic Transceiver Processor Assembly) is measuring power status(S201). In case that the ROPA is not measuring power status, the radio frequency controller confirms whether the target power of the remote optic transceiver is within the range of a target power the operator desires to control(S202). If the target power is within the desired range, the radio frequency controller transmits the power status measurement message to the ROPA(S203). The ROPA starts to measure the power status of the remote optic transceiver using the target power of the status measurement message(S204) and reports a measured result to the radio frequency controller(S205). The radio frequency controller determines the result(S206) and reports the transmitting power and gain of the remote optic transceiver to the base station operator(S207).

Abstract: PURPOSE: A method for acquiring a chaos multi-value of a digital data is provided to use an AD converter as a quantizer in a loop of one dimensional chaos generation mapping circuit, the DA converter and a nonlinear AD converter. CONSTITUTION: A chaos multi-value acquirement method comprises steps of making a loop by connecting a DA converter and a nonlinear AD converter to one dimensional chaos generation mapping circuit, acquiring a digitally coded multi-value from outputs of the AD converter, sampling analog outputs of the one dimensional mapping circuit by using an external clock to determine an operating speed of IC cells acquiring the multi-value and constructing a nonlinear quantizer with the DA converter and the nonlinear AD converter. The nonlinear characteristics of the AD converter can be designed with a channel capacitance of a MOS transistor in the process of designing an IC mask of the AD converter. The AD converter can be varied with a resolution, in general from 6 bit to 16 bit.
