Title: Tachogenerator output signal processor
Inventor: SETH SIYA VALLABH
IPC: H03K5/1532
Filed: 1981-07-31
Abstract: For processing the a.c. output of a tachogenerator when running at or above a given minimum speed to provide at least one output pulse for each complete output cycle, the processor includes a first voltage comparator 4 which responds to a first voltage level, lying between substantially zero and three quarters of the half cycle peak voltage, of the a.c. output signal of a tachogenerator 1 to provide a signal A which is present for substantially the whole of every half cycle of one polarity. This signal causes a latch, comprising and AND-gate 8 and a clocked D-type flip- flop 7, to be set to one of its two states by the signal A. A second voltage comparator 5 gives an output signal B in response to a voltage between one third and three quarters of the peak voltage in each half cycle of the other polarity which preferably also equals or exceeds half the peak voltage of the tachogenerator concerned when operating at its predetermined minimum speed. The latch can only be set to its second state by signal B and an output pulse can only be given by the processor whilst the latch is in its second state. <IMAGE>

Title: Gaming or amusement-with-prizes machines
Inventor: FOSTER MICHAEL ALAN
IPC: G07F17/34
Filed: 1983-10-13
Abstract: A fruit machine has reels or electronic simulations of reels and a random feature in which the player can adjust their positions after a normal spin. The control for this is a trigger mechanism whose electronically determined speed of operation determines the extent of the adjustment the faster the more symbol positions the reels move on. A limit is imposed and trigger speeds exceeding that necessary to reach it cause the reels to reverse after moving the maximum allowed amount in one direction, the extent of reverse movement corresponding to the excess trigger speed. This principle can be applied to other gaming or amusement machines, such as pinball machines, having a reel or simulated movable element under player control. <IMAGE>
