Patent number: 5426703Abstract: An active noise eliminating system comprises microphones for detecting residual noise, speakers for generating noise elimination sound for interference with the residual noise, a noise generating condition sensor for generating noise condition, a controller for generating noise elimination signals inputted to the speakers and determined by the detected residual noise signals and the detected noise condition signal in accordance with a control algorithm including transfer functions between the speakers and microphones respectively. The transfer functions are updated on the basis of a test signal generated when noise sound diverges.Type: GrantFiled: May 15, 1992Date of Patent: June 20, 1995Assignee: Nissan Motor Co., Ltd.Inventors: Tsutomu Hamabe, Akio Kinoshita, Kazuhiro Doi, Yoshiharu Nakaji, Kenichiro Muraoka

Patent number: 5384853Abstract: An apparatus for active reduction of noises transmitted from a noise source into a space. The active noise reduction apparatus comprises residual noise sensors for detecting the residual noises in the space. A reference signal is produced based upon the noise generating condition of the noise source. The reference signal is used, along with the detected residual noises, to drive control sound sources so as to reduce the noises in the space. A filter is adjusted to correspond to acoustic transfer characteristics between the control sound sources and the residual noise sensors. An identification sound is generated to correspond to the background noise level detected in the space and to the spectral distribution of the noises transmitted into the space. The coefficients of the filter are updated according to acoustic transfer characteristics between the control sound sources and the residual noise sensors.Type: GrantFiled: March 18, 1993Date of Patent: January 24, 1995Assignee: Nissan Motor Co., Ltd.Inventors: Akio Kinoshita, Kazuhiro Doi, Kenichiro Muraoka, Isutomu Hamabe

Patent number: 5340960Abstract: A control apparatus for carrying out a spot welding operation using a robot comprises a spot welding gun having a spot welding tip, an electric drive mechanism for driving the tip, and a control unit for controlling the electric drive mechanism, in which the operation of the spot welding gun is synchronously controlled with that of the robot. The electric drive mechanism is composed of an electric drive servo mechanism comprising a servo amplifier, an electric drive servo-motor and a spot welding tip driving unit. The control unit comprises a central processing unit, a random access memory, a read only memory, a timer and an input/output interface which is operatively connected to the servo mechanism and the spot welding gun. The control apparatus further comprises an input unit, a tip position detector, a robot driving unit and a robot position detector, all of which are connected to the control unit.Type: GrantFiled: October 7, 1992Date of Patent: August 23, 1994Assignee: Kawasaki Jukogyo Kabushiki KaishaInventors: Denjiro Takasaki, Shuichi Togawa, Akio Kinoshita, Hitoshi Arasuna

Patent number: 5325437Abstract: In an apparatus for reducing noises in a space, signals related to noise generating conditions of a plurality of noise sources are detected, a signal component of the detected signals is selected on the basis of determination of which signal component is predominant over the other signal component in the noises in the space, and the selected signal component is filtered through adaptively determined filter coefficients to output drive signals to control sound source, the filter coefficients being updated through a control algorithm so as to reduce a residual noise of a residual noise detector such as microphones. The signal components to be selected include a signal component having a relatively high auto-correlated function characteristic and a signal component having a random characteristic.Type: GrantFiled: December 23, 1992Date of Patent: June 28, 1994Assignee: Nissan Motor Co., Ltd.Inventors: Kazuhiro Doi, Akio Kinoshita, Kenichiro Muraoka

Patent number: 5295192Abstract: A method for electrically attenuating a noise in an area for a sound wave to be propagatable in a three dimensional direction by making up a drive signal from the information on the noise and previously given filter coefficients by use of an adaptive digital filter and then generating an additional sound wave in accordance with the drive signal for cancellation of the noise. In the electric noise attenuation method, there are provided in a given region for noise attenuation, first and second error sensor groups for detecting an interference sound wave produced between the noise and additional sound wave, at a sampling time, a filter coefficient is calculated based on the information relating to the first error sensor group, at the next sampling time, another filter coefficient is calculated based on the information relating to the second error sensor group, and these operations are repeatedly executed sequentially for each error sensor to thereby update the filter coefficient of the adaptive digital filter.Type: GrantFiled: October 6, 1992Date of Patent: March 15, 1994Assignees: Hareo Hamada, Tanetoshi Miura, Nissan Motor Co., Ltd., Hitachi Ltd., Bridgestone Corporation, Hitachi Plant Engineering & Construction Co., Ltd.Inventors: Hareo Hamada, Tanetoshi Miura, Akio Kinoshita, Noriharu Sato, Keiichiro Mizuno, Minoru Takahashi
