摘要： An active noise control system includes a plurality of vibration pickups for detecting of physical quantities of noise sources, such as vibrations of suspension members of a vehicle, and a plurality of microphones for detecting residual noises transmitted to observing positions. The output signals of the vibration pickups are added up by means of an adder to be input to a controller. The active noise control system also includes a plurality of delay circuits for applying delay times to the respective output signals of the vibration pickups so as to essentially equalize transmitting time of one of the output signals with that of the other output signals. The output signals of the microphones are input to the controller independently of each other. The controller outputs drive signals to a plurality of loudspeakers independent of each other to cause the loudspeakers to produce control sounds so that the control sounds interfere with the noises transmitted from the noise sources to decrease the noises transmitted to the observing positions.

摘要： A video encoding device includes a planar prediction unit using planar prediction, and a noise injecting unit for injecting pseudo-random noise into a prediction image of a planar prediction block when a reconstructed prediction error value for planar prediction is less than a threshold determined by the size of the planar prediction block. The video encoding device then uses the pseudo-random noise in linear interpolation for calculating the prediction image, based on the conditions under which a gradient distortion occurs, to suppress the gradient distortion.

摘要： A driver condition determination device determines whether a driver of a host vehicle has degraded consciousness. A main component for distribution of an accelerating operation condition with respect to proximity when tailgating a preceding vehicle is analyzed (S16), all data is origin-shifted (S18), and the accelerating operation condition of the driver when the driver has consciousness is created as a normal traveling model (S20). The likelihood of the accelerating operation condition, a likelihood average, a likelihood variance, and a likelihood threshold value are calculated (S22 to S26), and it is determined whether the likelihood of a current driving operation is lower than the likelihood threshold value (S28). When the likelihood is lower than the likelihood threshold value, the driver is determined as being in degraded consciousness. Since the likelihood threshold value is calculated for determination on the basis of data when the driver has consciousness, an erroneous determination of degraded consciousness due to difference in driver operation characteristics is suppressed.
