Abstract: An ultrasonic testing device includes: a signal acquiring unit which receives a reflected echo signal relating to a reflected echo of ultrasonic waves from an object being inspected, a defect detecting unit which detects a defect of the object being inspected on the basis of the reflected echo signal, and a display unit which displays the detection result of the defect detecting unit. The defect detecting unit uses the maximum signal strength of the reflected echo signal exceeding a first threshold value to detect the defect. The first threshold value is a value with which the signal strength is less than the maximum signal strength of the reflected echo signal from the surface of the object, using as an evaluation range an interval between a position which is positioned a first distance from the surface of the object and a bottom surface of the object.

Abstract: Methods, systems, and computer-readable storage media for providing high-resolution assessment of the condition of pipes of a fluid distribution down to the individual pipe stick. An acoustic sensor is placed in acoustical communication with a pipe at one end of a target segment. An acoustical wave is generated in the pipe at a first out-of-bracket excitation location while signal data is recorded from the acoustic sensor. Timing information regarding the arrival at the acoustic sensor of reflections of the acoustic wave from pipe joints in the target segment is extracted from the recorded signal data, and a time delay between reflections from consecutive pipe joints is computed. An acoustic propagation velocity in a pipe stick between the consecutive pipe joints is then computed based on the time delay and a length of the pipe stick. A condition of the pipe stick is determined based on the computed acoustic propagation velocity.

Abstract: A nebulizer has an aperture plate, a mounting, an actuator, and an aperture plate drive circuit (2-4). A controller measures an electrical drive parameter at each of a plurality of measuring points, each measuring point having a drive frequency; and based on the values of the parameter at the measuring points makes a determination of optimum drive frequency and also an end-of-dose prediction. The controller performs a short scan at regular sub-second intervals at which drive current is measured at two measuring points with different drive frequencies. According to drive parameter measurements at these points the controller determines if a full scan sweeping across a larger number of measuring points should be performed. The full scan provides the optimum drive frequency for the device and also an end of dose indication.

Abstract: A method for authorizing an update of a switching threshold of a magnetic-field sensor for an internal combustion engine of a motor vehicle, in order to ensure an immunity of the sensor to external magnetic disturbances. The sensor detects magnetic-field variations induced by a passage of the teeth of a target in proximity to the sensor, by generating a magnetic signal exhibiting oscillations, certain of which may be due to magnetic disturbances and be not to be taken into account in the update by the sensor of the switching threshold, which is recomputed depending on a detected amplitude of at least two consecutive oscillations of the magnetic field. An update of the switching threshold is suspended when an oscillation frequency computed between the at least two consecutive oscillations is higher than a maximum oscillation frequency computed from a predetermined speed of rotation of the engine and from the number of teeth on the target.
