    • A system and method of determining cardiac output from a cardiac pressure waveform. The pressure waveform is continuously sensed and converted into a digital data stream. When a complete beat frame of data is sensed, the processor extracts a plurality of features from the sensed waveform which characterize the waveform. These features are compared to stored representative pressure waveforms (RPW's) which have a known cardiac output. The RPW's are obtained by applying a pattern recognition methodology to pressure waveforms of known cardiac output. In one embodiment the typical shapes function is used. The pattern recognition methodology results in classes and associated cardiac outputs which are stored as the RPW's. The features extracted from waveforms representative of unknown cardiac output are thus classified by the comparison to the RPW's. When a match is made between the extracted features and an RPW, the cardiac output of the selected RPW is output as the cardiac output of the patient.
    • 一种从心脏压力波形确定心输出量的系统和方法。 压力波形被连续感测并转换为数字数据流。 当感测到完整的拍摄数据帧时,处理器从表征波形的感测波形中提取多个特征。 将这些特征与具有已知心输出量的存储的代表性压力波形(RPW)进行比较。 RPW是通过对已知心输出量的压力波形应用模式识别方法获得的。 在一个实施例中,使用典型的形状函数。 模式识别方法导致存储为RPW的类和相关的心输出量。 因此,通过与RPW的比较来分类从表示未知心输出量的波形中提取的特征。 当在提取的特征和RPW之间进行匹配时,所选RPW的心输出量作为患者的心输出量被输出。

    • Systems and apparatus are described for modifying fluid flow in a hard disk drive system to reduce cross-track motion. The systems and methods provide advantages because they include at least one flow modification element. In some embodiments, the flow modification system comprises a set of approximately parallel combs occupying a portion of the space present in between the disks in the hard disk drive system. The combs change the flow pattern of the fluid and act as a momentum channeling mechanism relative to the actuator assembly and suspension assemblies resulting in a considerable reduction in track misregistration error. Various embodiments of the invention include baffle-integrated combs, fixture-integrated combs, contoured enclosure surfaces, and enclosure attached combs.
