Title: Inverter for back-light of LCD
Inventor: MIN BYEONG UN
IPC: G02F1/133
Filed: 2001-12-27
Abstract: PURPOSE: A backlight inverter is provided to prevent a mis-operation at an initial driving state while performing a stable output control against the change of input voltage at an opening of a corresponding lamp when plural lamps are used for a backlight. CONSTITUTION: Rectifiers are equipped in each feedback signal to detect the size of voltage according to an on/off status of each backlight lamp. The rectifiers level the input feedback signals. Switching devices are turned on/off according to the state of the rectified feedback signals by connecting with the rectifiers one to one. A comparator receives and compares a reference voltage through a non-inversion terminal and a charging voltage of a condenser in an inversion terminal, feeds a voltage signal according to the compared result to a buck switch and controls the operation of the buck switch. A charging/discharging path control device forms charging/discharging paths of the condenser to be accessed to the inversion terminal of the comparator according to the on/off state of the switching devices.

Title: Absolute steering angle set up method in eps system
Inventor: KIM SEONG GYU
IPC: B62D6/00
Filed: 2001-12-27
Abstract: PURPOSE: A setting method for an absolute steering angle of an electronic power steering system is provided to check the absolute steering angle over all ranges of vehicle speed by setting a neutral steering angle as the absolute steering angle when a setting standard is satisfied and setting a stored steering angle as the absolute steering angle when the setting standard is not satisfied. CONSTITUTION: Whether a setting standard of an absolute steering angle is satisfied is checked(S11,S12,S13,S14). A neutral steering angle is set as the absolute steering angle when the setting standard is satisfied(S15). The absolute steering angle is renewed by adding angle changes according to displacement of a relative steering angle of a motor to the absolute steering angle(S16). The renewed absolute steering angle is stored(S17). A previously stored steering angle is set as the absolute steering angle when the setting standard is not satisfied. The absolute steering angle is renewed by adding angle changes according to displacement of the relative steering angle of the motor to the absolute steering angle. The renewed absolute steering angle is stored. Thereby, a recovering operation is operated by checking the absolute steering angle over all ranges of vehicle speed.
