    • A method for signal evaluation, e.g. with pulse wheels, is described, in which the distance between predeterminable signal edges is determined in a microcontroller that has a CPU, timer, and memory, in that upon the occurrence of signal edges, an interrupt is triggered with which the existing timer values are stored. Based on the difference between predeterminable timer values, time intervals are determined which are inversely proportional to the velocity or speed. So that it is possible to use timers with a relatively low bit count, for example 16 bits, the numerical values obtained when there is a timer overflow are also determined and are taken into account in the determination of the distances. If drum stores are used, only four bits per drum store value are required, one check bit and three bits as an overflow counter.
    • 一种用于信号评估的方法,例如 描述了其中在具有CPU,定时器和存储器的微控制器中确定可预定信号边缘之间的距离,因为在发生信号边沿时,触发中断以使现有的定时器值为 存储。 基于可预定的定时器值之间的差异,确定与速度或速度成反比的时间间隔。 因此,可以使用比特计数相对较低的定时器,例如16位,当定时器溢出时获得的数值也被确定,并且在距离的确定中被考虑。 如果使用鼓存储,则需要每个磁鼓存储值只有四位,一个校验位和三位作为溢出计数器。

    • In a method for determining the position of an object with reference to a measurement device having an optical transmitter which emits a light beam at a varying transmission angle, and having an angularly resolving optical receiver spaced away from the transmitter, a conclusion being drawn, from the respective transmission angle and from the respective angle at which the receiver receives radiation reflected from the object (reception angle), as to the resolution cell, defined by the angular resolution of the transmitter and the receiver, in which the object is located, the light beam emitted from the transmitter is modulated. The phase difference between the modulation of the transmitted light beam and the modulation of the received radiation is measured. From the phase difference, the position of the object within the respective resolution cell is calculated.
