摘要： A device for and method of providing reliable audible and visual warnings of incipient preignition in a combustion chamber is disclosed. The current flow through at least one engine spark plug is monitored at specified times throughout a number of engine revolutions during which there should be no current flow and both an audible alarm and a visible alarm are activated in the event the monitored current flow exceeds a predetermined threshold. Circuitry establishes time intervals during which there should be no current flow through the monitored spark plug and additional circuitry temporarily provides both an audible alarm and a visible alarm for each occurrence of the monitored current exceeding the predetermined threshold. Such a temporary alarm typically has the same duration as the detected excess current. There is also circuitry for continuously enabling both the audible and visible alarms in the event of an excessive number of excessive monitored current flows within a specified length of time.

摘要： A method and apparatus for writing a vector of data into a random access memory at high speed wherein the random access memory (RAM) is partitioned into blocks of addressable storage sites and wherein storage sites within each block are individually accessible. A vector generator provides addressing and storage site enabling signals to the RAM. Boundary detectors monitor the addressing and storage site selection signals to determine whenever storage sites within a new block of storage sites are sought to be addressed. When a boundary transition is detected, a control signal is provided to the vector generator which slows the operation of the vector generator for a period of time sufficient to permit the RAM to accept a new address. For all other addresses, the vector generator is permitted to operate at a higher speed wherein access to the RAM is made by way of enabling specific storage sites within the block of storage sites being written into. The invention further providing a method and apparatus for generating surface-fill vectors, wherein a vector generator which implements the Bresenhem Algorithm is employed to generate instructions for locating points corresponding to line segments that bound the surface to be filled. The instructions are evaluated such that the X address for a given point is recorded whenever an instruction is issued which indicates a Y address change. The recorded X address are correlated to the Y coordinates over which the surface extends. The correlated X and Y addresses then define end points of surface fill vectors which can fill in the surface.
