    摘要: In determining a knock of an engine, a vibration intensity is calculated by logarithm-transforming a peak value or an integral value of an output signal of a knock sensor. Further, a central value VMED of a vibration intensity distribution is calculated, and also a standard deviation σ in a region where the vibration intensity is smaller than this central value VMED is calculated. A vibration intensity reference value VIB is calculated as VMED−u×σ, thereby setting the vibration intensity reference value VIB to be close to a minimum of the vibration intensity distribution. Further, a knock reference value KCK is set by adding a predetermined value K to the vibration intensity reference value VIB. The vibration intensity detected by the knock sensor is compared with the knock reference value KCK to determine presence/absence of a knocking.

    摘要: A method and apparatus of dynamically storing critical data of a gaming machine by allocating and deallocating memory space in a gaming machine is disclosed. One or more embodiments describe downloading or removing a new game to a gaming machine such that all existing critical data in NV-RAM memory is left intact. In one embodiment, the invention discloses a method and apparatus for dynamically allocating and deallocating memory space to accommodate either permanent or temporary storage in an NV-RAM. A method and apparatus is provided to monitor available memory space and dynamically resize the memory in NV-RAM. In one embodiment, a method is disclosed for performing an integrity check of the NV-RAM and determining whether a critical data error has occurred. In one or more embodiments, methods of compacting and shifting contents of an NV-RAM are described to consolidate available memory space or to prevent unauthorized access of NV-RAM memory.

    摘要: A program and method enables easy creation and manipulation of timing charts. The preferred embodiment employs off-the-shelf commercial software and uses Visual Basic commands to get timing chart drawing commands into the drawing program and out of the spreadsheet program to order the drawing program to produce a displayable and print/plotable file. The user can easily see changes needed and even if they require ripple-through redrawing, because the user manipulates data in the spreadsheet file instead of directly manipulating drawing commands, the spread sheet will carry through ripple-through calculations to modify all lines related to the recalculated data.
