Title: A air-fuel ratio decision method using oxygen sensor
Inventor: BAE HO UNG
IPC: F02D41/04
Filed: 2000-12-06
Abstract: PURPOSE: A method for deciding an air-fuel ratio by using an oxygen sensor is provided to prevent the increase of exhaust gas due to the delay of air-fuel ratio feedback control by avoiding the delay due to the aging of an oxygen sensor. CONSTITUTION: A method for deciding an air-fuel ratio by using an oxygen sensor comprises the steps of deciding if engine rpm is within a specific range in an air-fuel ratio feedback control mode(S2), deciding if an absolute manifold pressure is within a specific range(S3), deciding if a throttle valve opening degree change is less than a reference change(S4), measuring a period of voltage signal outputted from an oxygen sensor(S5), comparing a value obtained by dividing a reference period of voltage signal by the measured period to a reference value(S6), calculating a rich air-fuel ratio and a lean air-fuel ratio if the calculated value is less than the reference value(S7), storing the air-fuel ratios in a memory(S8), and performing air-fuel ratio feedback control by applying the air-fuel ratios(S9). If the oxygen sensor is aged, the rich air-fuel ratio is decreased. Therefore, the delay of the air-fuel ratio feedback control is avoided.

Abstract: PURPOSE: A method for detecting data in 95B data service in an IMT-2000 system is provided to detect data all without any loss, even though one or more ISLP(Inter System Link Protocol) SDUs(Service Data Units) exist in the rate-synchronized ISLP PDUs(Protocol Data Units) inputted through a serial interface. CONSTITUTION: An IMT-2000 system executes a search routine(ST11). Then the system executes bit alignment in order to find out an ISLP open flag(ST12). In case that the open flag is detected(ST13), the system confirms whether the present data are the last data(ST14). Meanwhile, if another data, other than the open flag, are detected, the system executes an extraction routine after storing the start point of the detected data(ST17). Then the system checks whether '0' is inputted by insertion(ST18). The system checks whether the detected data are composed of 5 consecutive 1s(ones)(ST19). In case that the detected data are 5 consecutive 1s, the system removes '0' after the five 5 consecutive 1s(ST20). Then the system confirms whether a close flag is detected(ST21). If the close flag is detected, the system adds the amount of the detected ISLP SDU data to the stored data start point and stores the summed value as the start point for the detection of the next data(ST24).

Abstract: PURPOSE: A receiving method of a mobile communication system is provided to remove a ring sound according to user selection, to minimize a cellular phone noise, and to transmit a location of a current terminal to other terminal located in a predetermined area by a text message, when the current terminal enters the predetermined area, so as to recognize the location of the current terminal in real time. CONSTITUTION: A base station receiving a caller ID and a receiving call transmits the caller ID and the receiving call to a called terminal(301). A receiving sound generator receiving the receiving call makes a user audio-visually recognize the receiving call by vibrating or turning on/off a lamp(303). A controller receiving the caller ID provides the caller ID to a display window. The display window displays the caller ID(305). The controller confirms the displayed caller ID(307), and decides whether a predetermined key is inputted to remove a receiving sound(309). If so, the controller generates a control signal to remove the receiving sound. The receiving sound generator removes the receiving sound(311). The controller checks whether a speech key is inputted(313). If so, the controller provides a call signal to a call processor. The call processor processes the call signal(315). If the speech key is not inputted, the controller converts to a voice mail system to induce a caller to leave a message(317), and completes the procedure.
