摘要： The energy of the sound radiation caused by the impact of the coin to be analyzed upon a hard surface is split into different frequency bands, the energy of every such band is obtained and the ratios between them are then worked out, obtaining parameters that are then compared against values representing valid coins.
The device includes a bank of filters (6, 7 and 8), integrators (9, 10 and 11) connected to the outlet of the filters and capable of being activated from a microprocessor (17) and an analogue-digital converter to which the output of the various integrators is then connected through a multiplexer.-

摘要： Device for the successive exposure of images in amusement machines, like slot machines or fruit machines, made up of a structure (1) that supports two consecutive synchronized dragging rollers (3 and 4), at least two consecutive fixed position guiding rollers (5 and 6) and two non consecutive, removable, adjustable position guiding rollers (7 and 8), upon which rollers is mounted a flexible continuous strip (22), bearing images that pass in front of a viewing window, near which are fitted lighting means (23), including furthermore means (30,31,32,35) used to control the position of the images.
The image strip may be easily disassembled and removed, using a fast anchorage system, making it possible to clean or replace the image strip very quickly, and it is possible to keep constant the pulling force and length of the section of image strip that runs in front of the viewing window, thus ensuring the proper positioning in front of the viewing window and avoiding friction against the running track that includes the viewing window.
The image strip control means are capable of detecting the displacements of the image strip and of ensuring the proper positioning of the images in front of the viewing window.
