摘要： A module (28) for sensing the edges of a banknote as it passes through the module. The module consists of an array of LEDs (32) optically coupled to a light diffusing element (36) past which the banknote moves. A CCD array (40) has photoelectric conversion elements coupled to the path in which the banknote moves by a self-focusing fibre-optic lens array (38). The CCD array consists of four segments (42, 44, 46, 48) having individual shift registers which are read out in parallel, and converted to digital signals by a number of comparators (56). The comparators compare the CCD pixel output with individual threshold levels which are stored in a digital memory (54). The pixel threshold levels are converted to an analog signal for comparison with the CCD output signals by digital to analog converters (54). The digital data streams produced are divided into series of data which are analysed to determine the presence of an optical transition in the corresponding pixel series of the CCD arrays. If a transition is identified, the location of the pixel series is transmitted to a memory (58) for use in banknote validation.

摘要： A method of testing coins comprising at least taking two measurements of an unknown coin: and accepting said unknown coin as corresponding to a first coin type if the point defined by the measurements lies, in the space defined by the axes of the measurements, on a first side of a discriminant surface at which the Mahalanobis distances of the centres of the distribution of said first coin type and a second coin type are in a predetermined relationship, characterised in that said relationship corresponds (at least approximately) to equality of the sums of the respective Mahalanobis distances with respective predetermined constants at least one of which is non-zero.

摘要： An oval-shaped sensor is used to measure the material content of the outer ring of a bicolour coin, the coil being mounted on a ferrite whose inner portion has a diameter which is wider than the inner disc of the bicolour coin so that eddy currents are confined to the outer ring. A thickness sensor may be mounted within the oval sensor, and a separate coil is used for measuring the material content of the inner disc. The thickness sensor may also be used for measuring material down to a different depth, for validating clad coins. The oval sensor is used also for diameter measurement.
摘要翻译：椭圆形传感器用于测量双色硬币外圈的材料含量，该线圈安装在铁氧体上，铁氧体的内部直径比双色硬币的内盘宽，因此涡流是局限于外圈。厚度传感器可以安装在椭圆形传感器内，并且使用单独的线圈来测量内盘的材料含量。厚度传感器也可用于测量材料直至不同的深度，以验证复合硬币。椭圆形传感器也用于直径测量。
