    • A device for picking up the position of an angle of a rotating part which is provided with angle markers 11 or teeth being simultaneously distributed over its circumference, whereby at least one angle marker and/or intermediate space between two angle markers is shaped differently serving as a reference marker 12. This can be realized, for example, by a wide or smaller angle marker or gap between two angle markers. The distance between two angle marker flanks is picked up by a counter 17 which counts a cycle frequency, whereby the counter is a free running continously counting counter. The instantaneously present counter level is transmitted into a storage 18 for each angle marker flank (ascending flank or rear flank) to be evaluated. Subtractions of two successive storage values and comparisons of successive corresponding differential values are performed for recognizing a reference marker. A reference marker signal is generated during a deviation of a differential value by a predetermined dimension from the established differential value, preferably before or after.

    • To permit change of data, to be used in a fixed program carried out by a microprocessor (1) in accordance with a stored program (2), upon change in operating characteristics of a controlled apparatus (M), for example an internal combustion engine, an erasable programmable read-only memory (3) is provided, which is external to the microprocessor (1). The external memory (3) forms a combined address and data memory having at least one address field (4), and a vector field (5). A constant data field (7) and a table, or function data field (6) are part of the external memory (3), which data fields contain data to be addressed directly through the address field or via the vector field for not only a single type or series of apparatus, such as ICEs, but also additional engines, or engine characteristics, for example due to aging. In order to run the program by the microprocessor 1, with a changed or aged engine, then, it is only necessary to change the address of the data in the data field and/or the vector field to provide different output data for any given programming step.
    • 为了允许在根据存储的程序(2)由微处理器(1)执行的固定程序中改变数据,在受控设备(M)的操作特性的变化时,例如内燃机 提供了可微处理器(1)外部的可擦除可编程只读存储器(3)。 外部存储器(3)形成具有至少一个地址字段(4)和矢量场(5)的组合地址和数据存储器。 恒定数据字段(7)和表或功能数据字段(6)是外部存储器(3)的一部分,哪些数据字段包含要通过地址字段直接寻址的数据,或通过矢量字段,不仅仅是 单一类型或一系列设备,例如ICE,还包括额外的发动机,或发动机特性,例如由于老化。 为了由微处理器1运行程序,使用变更或老化的引擎,则只需要改变数据字段和/或矢量字段中的数据的地址,以便为任何给定的编程提供不同的输出数据 步。
