摘要： A cutting insert includes a top chip face, a bottom surface and side faces extending therebetween. At each of the end faces the cutting insert has axially protruding portions, each of which having a bevel. Main cutting edges are provided by the intersection between the top face and respective side surfaces. On each side surface there is provided a clearance portion formed on a protruding portion of the insert body which via a step extends into a secondary helically twisted clearance surface, the chip angle of which increases with increasing cutting depth. With the cutting insert viewed in plan, the bevel is oriented perpendicularly to the main cutting edge.

摘要： An apparatus for detecting cardiac events in electrograms has a feature extraction unit that derives features of the cardiac events for discriminating among different types of cardiac events. A clustering unit groups cardiac events with similar features into respective clusters defined by predetermined cluster features. The feature extraction unit determines a feature vector describing waveform characteristics of cardiac events in the electrogram by a wavelet transform. The clustering unit determines the distance between the feature vector and corresponding cluster feature vectors in order to assign the cardiac event in question to that cluster which results in a minimum distance, providing that the minimum distance is less than a predetermined threshold value. A heart stimulator provided with such a cardiac event detecting apparatus detects the occurrence of an arrhythmia and appropriately controls a pulse stimulator to treat the arrhythmia.
摘要翻译：用于检测电描记图中的心脏事件的装置具有导出心脏事件特征的特征提取单元，用于区分不同类型的心脏事件。聚类单元将具有相似特征的心脏事件组合成由预定的聚类特征定义的各个簇。特征提取单元通过小波变换来确定描绘电描记图中的心脏事件的波形特征的特征矢量。聚类单元确定特征向量与对应的群集特征向量之间的距离，以便将所讨论的心脏事件分配给导致最小距离的群集，只要最小距离小于预定阈值即可。设置有这种心脏事件检测装置的心脏刺激器检测心律失常的发生并适当地控制脉冲刺激器来治疗心律失常。

摘要： A cutting insert includes an upper chip surface, a bottom surface and side faces therebetween. At each of the end faces the cutting insert has axially protruding portions, each of which appears with a bevel face. Main cutting edges are provided in the intersection between the chip surface and the side surfaces. On each side surface is provided a clearance surface formed on a protruding portion which via a step clearance extends into a secondary helically twisted clearance surface, the chip angle of which increases with increasing cutting depth. The upper face includes along the main cutting edges a planar inclined surface with constant width that extends inwards and intersects with an upwardly inclined secondary chip breaking surface.
