Patent number: 11971694Abstract: An abnormal-sound detection device has an imaging unit, an operation range identification unit, a sound collection unit, an abnormal-sound detection unit, an abnormal-sound generation position identification unit, and an abnormal-sound source determination unit. The operation range identification unit identifies and stores the operation range of a diagnosis object on the basis of the image captured by an imaging unit. The abnormal-sound detection unit detects abnormalities in sounds included in the sounds collected by the sound collection unit, the sounds arriving from the diagnosis object. When an abnormality in a sound is detected by the abnormal-sound detection unit, the abnormal-sound generation position identification unit identifies the position at which the abnormality of the sound was generated.Type: GrantFiled: February 15, 2019Date of Patent: April 30, 2024Assignee: NEC CORPORATIONInventor: Mitsuru Sendoda

Publication number: 20210055705Abstract: [Problem] To provide an abnormal-sound detection device in which incorrect detection is rare. [Solution] An abnormal-sound detection device has an imaging means, an operation range identification means, a sound collection means, an abnormal-sound detection means, an abnormal-sound generation position identification means, and an abnormal-sound source determination means. The imaging means captures an image of a diagnosis object. The operation range identification means identifies and stores the operation range of the diagnosis object on the basis of the image captured by the imaging means. The sound collection means collects sounds arriving from the diagnosis object and the vicinity thereof. The abnormal-sound detection means detects abnormalities in sounds included in the collected sounds. When an abnormality in a sound is detected by the abnormal-sound detection means, the abnormal-sound generation position identification means identifies the position at which the abnormality of the sound was generated.Type: ApplicationFiled: February 15, 2019Publication date: February 25, 2021Applicant: NEC CORPORATIONInventor: Mitsuru SENDODA

Publication number: 20210048336Abstract: A device for generating an abnormal-sound determination reference has an imaging means, an action pattern discrimination means, a sound collecting means, an action sound discrimination means, and a reference action sound learning means. The action discrimination means discriminates and stores an action pattern of a diagnosis object on the basis of an image of the diagnosis object captured by the imaging means. The action sound discrimination means discriminates the action pattern discriminated by the action pattern discrimination means and a pattern of a sound collected in synchronization with the action pattern, and stores the pattern of sound as an action sound corresponding to the action pattern. The reference action sound learning means machine-learns an action sound corresponding to each action pattern for the stored action sound, and generates and stores a reference action sound corresponding to the action pattern.Type: ApplicationFiled: February 15, 2019Publication date: February 18, 2021Applicant: NEC CORPORATIONInventor: Mitsuru SENDODA

Patent number: 5392179Abstract: A magnetic read/write head assembly has a slider including a first and a second insulation films formed on the both surfaces of a distal end portion of a suspension arm, the first and the second insulation films being formed by a sputtering technology. The suspension arm has a generally thin plate configuration having a neck portion for serving a function similar to a gimbal spring for permitting freedom of motion of the slider. A small number of constituent parts, a small size and weight of the head assembly can be obtained for achieving a low flying height and a high recording density performance.Type: GrantFiled: March 26, 1993Date of Patent: February 21, 1995Assignee: NEC CorporationInventor: Mitsuru Sendoda
