    • A method for removing motion artifacts from devices for sensing bodily parameters and apparatus and system for effecting same. The method includes analyzing segments of measured data representing bodily parameters and possibly noise from motion artifacts. Each segment of measured data may correspond to a single light signal transmitted and detected after transmission or reflection through bodily tissue. Each data segment is frequency analyzed to determine up to three candidate peaks for further analysis. Each of the up to three candidate frequencies may be filtered and various parameters associated with each of the up to three candidate frequencies are calculated. The best frequency, if one exists, is determined by arbitrating the candidate frequencies using the calculated parameters according to predefined criteria. If a best frequency is found, a pulse rate and SPO2 may be output. If a best frequency is not found, other, conventional techniques for calculating pulse rate and SpO2 may be used. The above method may be applied to red and infrared pulse oximetry signals prior to calculating pulse rate and/or pulsatile blood oxygen concentration. Apparatus and systems disclosed are configured to perform methods disclosed according to the invention.
    • 一种用于从用于感测身体参数的装置和用于实现其的设备和系统的装置中去除运动假象的方法。 该方法包括分析表示身体参数和可能的运动伪影噪声的测量数据的段。 测量数据的每一段可对应于通过身体组织透射或反射后传输和检测的单个光信号。 对每个数据段进行频率分析,以确定最多三个候选峰进行进一步分析。 可以对最多三个候选频率中的每一个进行滤波,并且计算与最多三个候选频率中的每一个相关联的各种参数。 通过使用根据预定准则的计算参数来仲裁候选频率来确定最佳频率(如果存在)。 如果找到最佳频率,则可能会输出脉搏率和SPO2。 如果没有发现最佳频率,则可以使用用于计算脉率和SpO2的其它常规技术。 在计算脉搏率和/或脉动血氧浓度之前,上述方法可以应用于红色和红外脉搏血氧饱和度信号。 公开的设备和系统被配置为执行根据本发明公开的方法。

    • The present invention discloses and claims a novel process for the formation of high denier as-spun and heat-treated multilobal filaments of a thermotropic liquid crystalline polymer. Preferred embodiments include process for the formation of as-spun and heat treated octalobal monofilaments of a few wholly aromatic polyesters and polyesteramides. The process involves (a) heating of a thermotropic liquid crystalline polymer to above its melting transition temperature; (b) passing said molten polymer through an extrusion chamber equipped with an extrusion capillary having a multilobal cross-section to form a multilobal filament; and (c) winding the filament at a suitable draw-down. The filaments so formed are of at least 50 denier per filament (dpf) and feature essentially uniform molecular orientation across their cross-section. In a final optional step, the filaments are heat treated in stages to form filaments exhibiting excellent tensile properties. Both as-spun and heat-treated filaments feature remarkably good tensile properties comparable to those of round filaments. Most importantly, the multilobal filaments of this invention feature much superior adhesion properties than the conventional round filaments.
    • 本发明公开并要求一种用于形成热致伸缩液晶聚合物的高旦旦纺丝和热处理多叶长丝的新方法。 优选的实施方案包括形成几种完全芳族聚酯和聚酯酰胺的初纺和热处理的八面体单丝的方法。 该方法包括(a)将热致液晶聚合物加热至其熔融转变温度以上; (b)使所述熔融聚合物通过装备有具有多叶横截面的挤出毛细管的挤出室以形成多叶长丝; 和(c)将丝缠绕在合适的拉伸下。 如此形成的细丝具有至少50旦尼尔/丝(dpf),并且在其横截面上具有基本均匀的分子取向。 在最后的任选步骤中,细丝被分阶段热处理以形成显示出优异拉伸性能的长丝。 初纺和热处理的长丝具有与圆丝相当的非常好的拉伸性能。 最重要的是,本发明的多叶长丝具有比常规圆丝更好的粘合性能。
