    摘要： An adaptive hauling canceller has a plurality of adaptive filters. A delay adds a time delay of an acoustic feedback path to an electric signal fed from an amplifier of a sound-reinforcement system. Each adaptive filter filters the output signal of the delay with a filter coefficient, which is periodically updated at an update interval. The update interval of each adaptive filter is set to decrease successively from a first one to a last one of the adaptive filters. Adders are arranged in correspondence to the adaptive filters in series between a microphone and the amplifier. Each adder subtracts the output signal of the corresponding adaptive filter from an output signal fed from a preceding adder to thereby provide an output signal to a succeeding adder. The output signal from each adder is inputted into the corresponding adaptive filter. The audio signal from the microphone is inputted to the first adder, while the output signal from the last adder is inputted through the amplifier to the speaker and to the delay as the electric signal. The filter coefficient of each adaptive filter is updated so as to simulate a transfer function of the acoustic feedback path based on the output signals of the corresponding adder and the delay.

    摘要： A solid-state imaging device is capable of simplifying the pixel structure to reduce the pixel size and capable of suppressing the variation in the characteristics between the pixels when a plurality of output systems is provided. A unit cell (30) includes two pixels (31) and (32). Upper and lower photoelectric converters (33) and (34), transfer transistors (35) and (36) connected to the upper and lower photoelectric converters, respectively, a reset transistor (37), and an amplifying transistor (38) form the two pixels (31) and (32). A full-face signal line 39 is connected to the respective drains of the reset transistor (37) and the amplifying transistor (38). Controlling the full-face signal line (39), along with transfer signal lines (42) and (43) and a reset signal line (41), to read out signals realizes the simplification of the wiring in the pixel, the reduction of the pixel size, and so on.

    摘要： An optical system that includes a molded optical element having a non-uniform refractive index distribution due to molding and a method of manufacturing the optical system is disclosed. Data of the non-uniformity of the refractive index distribution associated with molding of the molded optical element is acquired and used in order to determine the form of an aspheric surface of the molded optical element for correcting aberrations caused by the non-uniformity of the refractive index distribution. This data may be acquired by measuring the refractive index distribution of an optical element molded based on initial design values that are based on assuming uniformity in the refractive index distribution of the molded optical element or it may be computed based on the form of the molded optical element. The optical element may include a concave optical surface and may be a lens element that includes an aspheric surface.
