Abstract: 본 발명은 지반 보강을 위해 사용되는 특수 강관 제품에 대한 비파괴 검사방법에 관한 것으로, 더 상세하게는 강관에 음향을 제공하고, 강관을 통해 유출되는 음향을 추출하여 강관의 불량 여부를 판단할 수 있도록 한 음향신호를 이용한 강관 검사 시스템에 관한 것이다. 강관의 주된 불량 내용은 용접 불량에 따른 기공 또는 크랙(crack) 및 조관불량 임을 감안하여, 종래의 강관 검사는 일부 샘플에 대한 육안 검사가 일반적이다. 그러나 실상은 육안 식별은 어려우며, 특히나 제조물량을 모두 육안으로 검사하는 것은 어렵다. 따라서 비파괴 검사 방법을 적용한 전수검사 방법이 필요하다. 본 발명은 강관에 대하여 정해진 주파수와 진폭을 갖는 음향을 발생시키고 강관을 통해 전달되는 음향을 검출하고, 검출된 정보를 강관의 불량에 따른 학습된 음향분석정보와 대비하여 강관의 불량 유무를 판단할 수 있도록 하는 음향신호를 이용한 강관 검사 시스템을 제공하고자 한 것이다.

Abstract: A method of determining wear/ degradation levels of a consumable assembly of a welding/plasma torch may utilize a controlled sound signal in order to determine an acoustic profile or full spectral audio analysis dataset of the consumable assembly that facilitate the identification of patterns that correlate to certain wear/degradation levels of the consumable assembly. The full spectral audio analysis dataset may be obtained by subjecting a given consumable assembly to a controlled sound signal between operations and as the consumable assembly degrades over time. The full spectral audio analysis may serve as a wear/degradation profile over the life of the given consumable assembly. With a full dataset known for a particular consumable assembly model, an acoustic profile of another consumable assembly of the same model may be obtained and compared to the full dataset in order to identify the wear/degradation level of the tested consumable assembly.

Abstract: The invention relates to a method for non-destructively testing a specimen by means of acoustic waves. The method comprises the steps of: (S2) receiving from a testing device (5) at a measurement position, in mechanical contact with the specimen (4), raw data representing acoustic waves that propagated through the specimen (4); (S3) providing options to process the raw data by at least a first and a second processing algorithm; (S4) processing the raw data by at least one of the first and the second processing algorithm. The first processing algorithm comprises deriving information about the specimen (4) from multiple reflections of the acoustic waves. The second processing algorithm comprises deriving information about the specimen (4) from a travel time of a single reflection of the acoustic waves. Further, the invention relates to a system for carrying out the method, comprising a testing device. The testing device comprises a housing (1), a contact element (2) protruding 15 from the housing (1) and comprising a cavity (25), and an acoustic wave sensor (3, 51) mounted in the cavity (25).

Abstract: Ultrasonic sensing device for determining the status of an object near such ultrasonic sensing device. Emission signal having a current frequency or band in an ultrasonic frequency range is emitted. Ultrasonic signals are analyzed to detect one or more objects near the ultrasonic sensing device. After expiration of a predefined time period of emitting the emission signal, a background noise signal is detected from an environment of the ultrasonic device and background noise metrics are estimated based on the background noise signal. The current frequency of the emission signal is optimized based on the background noise metrics. A next frequency or band is selected and the emission signal is emitted at the next frequency or band if it is determined that the current frequency or band is not optimum. The operations of detecting, estimating, determining, and selecting are repeated after each time a next frequency or band is selected and the emission signal is emitted at such next frequency or band.
