This paper presents a correlative method for the real-time measurement of quality characteristics of propanated biomethane for pipeline injection according to the European and Swedish regulations. The target quality properties (superior calorific value and Wobbe index) were predicted by the developed regression model based on the measurement of a s...

The article demonstrates an effective solution for ultrasonic quality monitoring of transmission and drive components of motor vehicles, joined using an innovative method called magnetically impelled arc butt welding (MIAB). The major challenge was the application of ultrasonic technology for quick and reliable testing of thin-walled components wit...

The paper describes finger reader, that generates the picture of the fingerprint using the principle of acoustic holography and ultrasonic waves travelling parallel to the sensor surface. The idea realized in this unit allows the creation of devices based on thin plates with different sizes, able to replace typical touch screens, even of quite larg...

Sposób kontroli jakości połączeń elementów o kołowym przekroju zgrzanych doczołowe łukiem wirującym, zwłaszcza połączeń cienkościennych elementów rurowych w postaci półosi i wałów napędowych z końcówkami roboczymi w postaci wałów krótkich czy przegubów, w którym ocenę jakościową połączenia dokonuje się na podstawie analizy fali ultradźwiękowej któr...

The article presents the design methodology of automated set-up being used for the quality control evaluation of car drive shafts. The transmission elements were characterized, quanti ed and then the speci c objectives of a solution were de ned. The boundary conditions were also de ned. The various prototypes were designed, analyzed and compared in...

Non-destructive testing and functional tests are an integral part of the manufacturing process of components and constructions used in the automotive industry. The drive and transmission shafts joined by Magnetically Impelled Arc Butt (MIAB) welding process, continuously work under constant dynamic loads and must meet particularly high quality crit...

The paper describes the application of critically refracted longitudinal ultrasonic subsurface waves (LCR, known also as lateral, creeping or head waves) for nondestructive flaw detection in friction welding or MAIB welded thin walled pipe shaped parts. Theory and practical laboratory and industrial applications are presented. Keywords: ultrasonic...

W artykule zaprezentowano współczesne metody kontroli ultradźwiękowej elementów o przekrojach rurowych łączonych różnymi metodami spawalniczymi. Dla wybranych rozwiązań technologicznych przedstawiono zastosowanie wybranych prezentacji sygnałów ultradźwiękowych w różnych aplikacjach przemysłowych, głównie zautomatyzowanych. Ponadto przedstawiono ist...

This paper describes finger reader, that generates a fingerprint image using ultrasonic waves travelling parallel to the sensor surface in concert with the principle of acoustic holography. The idea realized in this unit allows for the creation of devices based on thin plates of varying sizes, from smaller than a postage stamp, to the largest live...

A new instrument for precise measurements of velocity of sound in gases was developed and tested. The instrument implements improved velocity of sound measuring technique based on time-of-flight measurement of ultrasonic pulses. The instrument was developed primarily for conducting measurements in natural gas, it can operate in wide ranges of natur...

The article presents currently used ultrasonic tests of elements having tubular cross-sections, joined by means of various welding methods. In addition, the article discusses various ultrasonic signals in industrial (primarily automatic) applications in relation to selected technological solutions as well as presents existing industrial stations fo...

This paper describes the design of an ultrasound camera which has a resolution of 0.1mm. The camera allows the observation of the near surface structures of solid objects and is suitable for the finger ridge pattern imaging (i.e., pattern which is reflected in a fingerprint). The device can be used for a biometric identification of individuals (for...
