    • A tracer head for effecting three dimensional tracing of a model surface in a highly efficient and precise manner is described herein. The tracer head has a base frame, a tracer shaft, a stylus mounted at one end of the tracer shaft for tracing said model surface, a plurality of supports for the tracer shaft provided at at least two locations on the base frame, each support including a member which has a moderate resiliency in the thrust direction of the tracer shaft as well as either a strong resiliency exceeding a certain extent or rigidity in the radial direction of the tracer shaft, displacement detectors mounted on the base frame, a rod spring forming a part of the tracer shaft disposed between the supports for transmitting movement of said stylus to a thrust direction displacement detector and having a moderate resiliency in the radial direction of said tracer shaft for being bent when the stylus is moved laterally, and a cylindrical transmission member for transmitting a movement of said stylus to the radial direction displacement detectors.

    • A biological signal drawing apparatus draws biological signals as drawing points in time series. The biological signal drawing apparatus includes: a thinner performing a thinning process to thin a first number of the drawing points corresponding to the biological signals sampled in each pixel zone, to obtain a second number of the drawing points for each pixel zone, the second number being smaller than the first number; a calculator, after the thinning process is performed, calculating a parameter based on at least one difference of values of adjacent two of the drawing points included in a group that includes: a first drawing point being a center in time series in the group and having a first value; and at least one second drawing point preceding or succeeding the first drawing point in time series and having a second value; and a processor performing a process of: performing a weighted moving average calculation using the first value, the second value and the calculated parameter, to obtain a third value; and replacing the first value with the third value.
    • 生物信号绘图装置以时间序列绘制生物信号作为绘图点。 该生物信号描绘装置包括:对每个像素区采样的生物信号对应的第一数量的绘图点进行细化处理,以获得每个像素区的第二数量的绘图点,第二数目 小于第一个数字; 计算器,在执行间隔处理之后,基于包括在组中的相邻两个绘图点的值的至少一个差异来计算参数,该组包括:作为该组中的时间序列中心的第一绘图点,并具有 第一个值 以及在第一绘图点之前或之后的至少一个第二绘制点,并且具有第二值; 以及处理器,执行以下处理:使用所述第一值,所述第二值和所计算的参数来执行加权移动平均计算,以获得第三值; 并用第三个值替换第一个值。
