1) Ruled surface interpolation methodAn analytical inverse transformation method based on calibration points for nonlinear multiple dimensional sensing system has been proposed. N-dimensional recursive interpolation based on ruled surface is described by N interpolation ratios. Interpolation equation is linear to every interpolation ratio, but the order for all interpolation ratios is N.This theory will be applied to human sensory system as follows.2) Measurement of fabric hand valueAn elastic touch sensor and an optical fiber whisker sensor have been constructed as a means for gathering fabric hand value information. When sensor was scanned over fabric surface, elastic sensor detects the resilience of single fabric sheet and flexibility of fold up fabric sheets. On the other hand fiber whisker vibrates to the scanning motion. The stick slip motion of fiber tip from which modulated laser light emits is detected optically by Positional Sensitive Device. Fiber whisker gathers much fabric hand value information, not only surface contour and surface friction, but also fabric resilience and extensibility. Sensor outputs are displayd by Symmetrized Dot Patterns to distinguish cotton, linen, silk and wool from each other. Further work is required to extend fiber whisker array with fiber condition's variations, and improve the mapping between human sensory evaluation and fiber whisker measurement. Then the ruled surface interpolation method will be applicable.3) Spatial filtering flow-meter with thin film thermal resistorsA technique to construct a flow-meter based on spatial filtering method is described Narrow-band-pass spatial filtering flow-meter indicates the flow velocity by detecting thermal frequency. Weighting quadratic differential spatial filtering flow-meter detects the mechanical travel time of thermal pulse. Analytical results and experimental results for these spatial filtering constructions are shown.

1)直纹面插值法提出了一种基于校准点的非线性多维传感系统的解析逆变换方法。用N个插补比描述了基于直纹面的N维递推插补。插补方程对每种插补比例都是线性的，但所有插补比例的阶数都是N。这一理论将应用于人类的感官系统如下：2)织物手值的测量构建了弹性触觉传感器和光纤胡须传感器作为采集织物手值信息的手段。当传感器扫描到织物表面时，弹性传感器检测单张布片的弹性和折叠布片的弹性。另一方面，纤维晶须随着扫描运动而振动。利用位置敏感装置光学检测调制后的激光发射出的光纤尖端的粘滑运动。纤维晶须收集了大量的织物手感信息，不仅包括表面轮廓和表面摩擦，还包括织物的弹性和延伸性。传感器输出通过对称化的圆点图案显示，以区分棉、亚麻、丝绸和羊毛。随着纤维状态的变化扩展纤维须阵列，并改进人类感官评价和纤维须测量之间的映射，还需要进一步的工作。3)薄膜热敏电阻空间滤波流量计介绍了一种基于空间滤波方法的流量计构造技术，窄带通型空间滤波流量计通过检测热频来表示流量。加权二次差分空间滤波流量计检测热脉冲的机械行程时间。给出了这些空间滤波结构的分析结果和实验结果。
