Title: Incarnation method of FIR filter in phase equalizer
Inventor: LEE JEONG HWA
IPC: H03H17/02
Filed: 2002-02-28
Abstract: PURPOSE: A method for forming an FIR(Finite Impulse Response) filter in a phase equalizer is provided to improve the magnitude of a phase equalizer by using system identification and an RLS(Recursive Least Square) adaptive algorithm. CONSTITUTION: An analog IIR(Infinite Impulse Response) filter is formed at a phase equalizer(S101). A coefficient value of the IIR filter is obtained by using a binary transform method and transforming a phase and a magnitude characteristic of the IIR filter(S103). A difference between an output of an unknown part and an output of an adaptive model is obtained by using an RLS adaptive algorithm(S105). A minimum value of the difference between the output of the unknown part and the output of the adaptive model is determined by feeding back the obtained difference to the adaptive model(S107). A coefficient value of an FIR filter is determined if the difference between the output of the unknown part and the output of the adaptive model is the minimum value(s109).

Title: Coupling mechanism for electrical connectors
Inventor: BERNARDINI J ALLEN
IPC: H01R13/627
Filed: 2002-03-14
Abstract: PURPOSE: A coupling mechanism for electrical connectors is provided to prevent impact and vibration, and to protect an electrical contact body by connecting a receptacle connector to a plug connector conveniently. CONSTITUTION: A coupling mechanism connects a plug connector(30) to a receptacle connector(20) by simply pushing the plug connector to lock into the right place on a receptacle connector and pulling the coupling nut to release. The plug and receptacle connectors are locked from relative circumferential motion or axial motion to each other when coupled. The locked connector prevents relative motion in applying to high shock and vibration units. The plug connector is contacted to the receptacle connector with considerable force. Advantageously, the locking condition of the locked connector protects the electrical contact from excessive wear created when relative motion exists between the plug connector and the receptacle connector for preventing loss of continuity, excessive heating and even combustion due to excessive heating.
