    • 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.

    • 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.
    • 一种用于将数据向量高速写入随机存取存储器的方法和装置,其中随机存取存储器(RAM)被划分为可寻址存储位置的块,并且其中每个块内的存储位置是可单独访问的。 向量生成器向RAM提供寻址和存储站点使能信号。 边界检测器监视寻址和存储站点选择信号,以确定寻找新的存储站点内的存储位置。 当检测到边界转变时,向矢量发生器提供控制信号,该矢量发生器使矢量发生器的操作减慢足以允许RAM接受新地址的时间段。 对于所有其他地址,允许向量生成器以更高的速度操作,其中通过使存储位置块内的特定存储位置被写入来进行对RAM的访问。 本发明还提供了一种用于产生表面填充向量的方法和装置,其中采用实现Bresenhem算法的向量生成器来生成用于定位对应于结合待填充表面的线段的点的指令。 评估指令,使得每当发出指示Y地址改变的指令时,给定点的X地址被记录。 记录的X地址与表面延伸的Y坐标相关。 相关的X和Y地址然后定义可以填充表面的表面填充向量的端点。

    • An spiral inductor (300) formed on a semiconductor substrate (102). One or more insulating layers (104, 303) is disposed on a first surface of the semiconductor substrate. A spiral structure (106) is formed of a first conductive material layer disposed on the insulating layer. The spiral structure has a terminal end (105) at a location enclosed by one or more coils of the spiral. A ground plane (302) is formed of a second conductive material and disposed on a second surface located on a side of the substrate opposed from the first surface. The ground plane is defected so as to define a signal trace (308) formed from a portion of the ground plane. A conductive via (304) extends through the one or more insulating layers, and through the semiconductor substrate, to form an electrical connection between the ground plane and the terminal end.
