A flexible screw type height control device comprises a housing, a servomotor mounted in the housing, a driving gear which is rotated by the servomotor, a driven gear which is provided with a spiral groove at a central portion thereof and is tooth-engaged with the driving gear, a flexible screw member which passes axially through the spiral groove of the driven gear and moves linearly upward and downward by the servomotor, and a telescopic unit including a plurality of sliding members which are slidably coupled to each other and cooperate with the flexible screw member. The flexible screw member is a coil spring. A first sliding member is slidably disposed in the housing. One end of the flexible screw member is extended outside the housing, and the other end is fixed to a last sliding member. Each sliding member is formed as an open-ended pipe and a cross-sectional area of the sliding members decreases from the first sliding member to the last sliding member.

The present invention relates to a method for measuring human intelligence using a neurobiogical model. The invention provides a method which enables neurometric IQ to be measured by processing the MRI and fMRI images of subjects to determine cortical thicknesses and brain activation levels, determining structural IQ (sIQ) and functional IQ (fIQ) from the cortical thicknesses and the brain activation levels, and using the structural IQ (sIQ) and the functional IQ (fIQ) as predictors to measure the neurometric IQ of the subject. According to the present invention, the concept of a neurometric IQ (nIQ) model is established and can assist in easily assessing individual differences in general cognitive ability. These results suggest that general cognitive ability can be explained by two different neural bases or traits: facilitation of neural circuits and accumulation of crystallized knowledge.

摘要:
The present invention relates to a monitoring device for a rotating body, which can accurately measure signals from a fiber Bragg grating sensor provided on the rotating body by compensating a transmission loss variation and a distortion of the sensor signals. A rotation-side optical fiber has at least one deformation sensor at a portion thereof and a reference sensor at one end thereof. The sensors are made by forming a Bragg grating in the rotation-side optical fiber. A fixed-side optical fiber is mounted to the fixed body so as to be opposed to the one end of the rotation-side optical fiber. A signal processing unit detects a deformation of the rotating body by subtracting a signal corresponding to the light reflected from the reference sensor from a signal corresponding to the light reflected from the deformation sensor.
