Abstract: An apparatus (14) for locating a source of acoustic mission in an article (10) comprises a plurality of spaced transducers (18) which supply output signals corresponding to detected acoustic emission activity to a processor (24). Artificially induced acoustic emissions (12) are generated in the article (10) by directing a laser beam (33) onto the article (10). A camera (40) produces an image of the article (10) and any laser flashes. A processor (42) converts the positions of the laser flashes to coordinates on the article (10). A processor (24) analyses parameters of the acoustic emission in the output signals and the coordinates of the laser flashes to infer the mathematical relationship between the parameters and location of acoustic emissions. The same parameters for acoustic emissions of unknown source location are used to calculate the location of the unknown source with the deduced mathematical relationship and the calculated coordinates are converted by processor (42) to a position on the image produced by the camera (40) and the processor (24) provides an indication of the accuracy of the calculation.

Abstract: The stress wave activity produced in a surface by a writing instrument during the generation of a given piece of handwriting is detected by a transducer and is electrically processed. The stress wave activity is compared with a stress wave activity, produced during at least one previous generation of the given piece of handwriting, held in a store, by a processing unit in order to determine whether the detected and stored handwriting pieces have a common author. If the detected and stored handwriting pieces are determined to have a common author a weighted average of the stored stress wave activity and the detected stress wave activity is produced. The weighted average includes a weighted average of the amplitudes and a weighted average of times of events. This weighted average stress wave activity then replaces the stored stress wave activity in the store. This allows natural variations in the way an individual writes a given piece of handwriting to be accommodated without false indications of inauthenticity.

Abstract: The method described herein includes providing an aerofoil structure having a root portion and an aerofoil portion, wherein the aerofoil portion has a tip remote from the root portion. In certain aspects, the tip of the aerofoil structure can be substantially surrounded by a casing with a clearance gap between the tip and the casing. In certain aspects, the method described herein includes disposing the aerofoil structure relative to the casing such that an oscillation of the aerofoil structure from an unperturbed position in a first direction reduces the clearance gap and that an oscillation from the unperturbed position in a second direction increases the clearance gap. In certain aspects, the method further includes disposing the aerofoil structure such that the frequency of the clearance gap variation is equivalent to the frequency of the aerofoil structure vibration and permits a flow through the clearance gap in which the flow tends to dampen the aerofoil structure vibrations.

Abstract: A method is provided whereby confidence in a validation parameter set is achieved by comparison with a known sample of a parameter in terms of the expected template comparison score as well as mean values and deviation from that score. Thus, with respect to user individual identification, biometric parameters such as fingerprint or handwriting or voice recognition can be utilised to compare the stored template for that individual with the putative biometric response in order to determine deviation from the mean. Previous systems provided a stored template and then ranging either side to simply give a pass/fail response. By adaptation of the ranging quotient for a particular individual, a percentage confidence in the pass/fail response can be achieved. For example an individual -may have a wider range of deviation than another individual and therefore close repetition of the biometric data may be indicative of a lower percentage confidence than with an individual with a narrower deviation. Furthermore, through a learning process, the ranging quotient may he varied as a users actual response varies with age or otherwise.
