In one or more embodiments, a surface acoustic wave (SAW) sensor is provided that can measure one or more of a magnetic field (or current that generates the magnetic field), temperature and humidity. In one or more embodiments, a magnetoimpedence (MI) sensor (for example a thin film giant magnetoimpedance (GMI) sensor), a thermally sensitive (for example a Lithium Niobite (LiNbO.sub.3)) substrate, and a humidity sensitive film (for example a hydrogel film) can be used as sensing elements.

An ultrasonic inspection probe assembly includes a flexible ultrasonic transducer array located between a backing block and a face layer. The flexible ultrasonic transducer array can be located in the opening of a flexible ultrasonic transducer array frame.

The method for examining a clinched portion of a tubular body includes the steps of: giving an elastic vibration to a clinched body 90 formed by clinching a tubular body 91 with a clinch-target member 92; and acquiring, for each of a plurality of view areas 95 which differ from each other in the position in the circumferential direction of the tubular body 91, a vibration distribution optically and simultaneously measured within the view area 95 including a clinched portion 93 of the tubular body 91 and the clinch-target member 92, to determine whether or not the state of clinching is satisfactory over the entire clinched portion 93.

An ultrasonic touch sensing system that uses both compressional and shear waves for touch and water detection is disclosed. When no touch or water is present, less shear and compressional wave energy is absorbed, so both shear and compressional wave reflections do not have significant amplitude decreases. When a finger is in contact with the sensing plate, both shear and compressional wave energy is absorbed, so both shear and compressional wave reflections have significant amplitude decreases. When water is in contact with the sensing plate, compressional energy is absorbed but little or no shear wave energy is absorbed, so while compressional wave reflections have significant amplitude decreases, shear wave reflections do not. From these amplitudes, a determination can be made as to whether no touch is present on the sensing plate, whether a touch is present on the sensing plate, or whether water is present on the sensing plate.
