Abstract: An apparatus for estimating an amount of noise is disclosed. The apparatus includes a FET processor that analyzes frequency components of an audio signal input to a speaker in a vehicle, a FET processor that analyzes frequency components of a signal output from a microphone in the vehicle, a coherence function calculator which detects a ratio of the audio signal included in the signal output from the microphone by calculating a magnitude squared coherence function based on the frequency components of the two signals analyzed by the first and second frequency analyzers, and a multiplier and adder which calculates an amount of external noise reaching the microphone separately from an audio sound corresponding to the audio signal on the basis of the signal output from the microphone and the ratio of the audio signal detected by the coherence function calculator.

Abstract: A conveyor belt having a reinforcing layer of a synthetic fiber woven fabric embedded between an upper surface cover and a lower surface cover, wherein an elongation at break of the synthetic fiber woven fabric in a belt longitudinal direction is at least 25% and an elongation at a load 10% of a guarantee strength is not greater than 1.5%.

Abstract: A vehicle light attachment mechanism is disclosed for attaching a vehicle light to a vehicle body. The attachment mechanism includes a pair of hooks arranged on the vehicle light, one of which is elastic and the other of which is non-elastic. Each hook can engage an aperture of the vehicle body in opposing directions. A positioning boss can be placed adjacent either the elastic hook or the non-elastic hook for extending through a positioning through hole on the vehicle body having a diameter corresponding to the diameter of the positioning boss. Furthermore, at least one projection boss may be provided to distance the housing and the vehicle body and spread external forces applied from the vehicle light toward the vehicle body over an outer surface of the vehicle body. At least one projection boss can also be used as a positioning boss to provide at least two positioning points in combination with said positioning boss for the housing.
