Abstract: PURPOSE: Fault detector and detecting method for the pose control system of a spacecraft are provided to reduce the fault detection and enhance performance by minimizing the generation of a model filter. CONSTITUTION: A fault detector for the pose control system of a spacecraft comprise a first mutual interference multi-model fault detecting block(120) and a second mutual interference multi-model fault detecting block(130). The first mutual interference multi-model fault detecting block generates a plurality of upper filters. The upper filters comprise a normal model filter for a plurality of drivers and a fault model filter for each driver. The first mutual interference multi-model fault detecting block detects fault on the drivers from the upper filters using a mutual interference multi-model estimating technique.

Abstract: PURPOSE: An artificial cochlea device for the active feedback controlling and a method thereof are provided to copy the mechanism of an outer hair cell of the cochlea through an actuator which is driven by the sound pressure, thereby classifying and recognizing various sizes of sound by the pressure deviation. CONSTITUTION: A sensor unit senses the vibration by sound, and generates an electric signal corresponding to the size of the vibration. The sensor unit comprises a plurality of operator (230) which moves a frequency dividing unit in response to the electric signal. The operator operates the sensitivity by the size of sound or the selectivity of sound which is sensed by each frequency band. A plurality of operator is arranged separately to a plurality of base unit (216). The plurality of operator is consecutively connected along a first substrate (210) or a second substrate (212). The operator moves up and down by the electric signal which is generated in the base unit and a nanopillar (214).

Abstract: PURPOSE: A fault detector for an RIMU(Redundant Inertial Measurement Unit) and a detecting method are provided to secure an improved fault detection performance because only signals of low frequency component from signals output from each inertial sensor are used for a modified extended PSA(Parity Space Approach). CONSTITUTION: A fault detector(100) comprises a signal processing unit(110) and a fault detection unit(120). The signal processing unit extracts low frequency component from the N numbers output of inertial sensors. The fault detection unit preforms the fault detection with respect to the inertia sensor through PSA by using the low frequency component of the inertial sensors offered by the signal processing unit.
