摘要： A method and an apparatus to analyze two measured signals that are modeled as containing desired and undesired portions such as noise, FM and AM modulation. Coefficients relate the two signals according to a model defined in accordance with the present invention. In one embodiment, a transformation is used to evaluate a ratio of the two measured signals in order to find appropriate coefficients. The measured signals are then fed into a signal scrubber which uses the coefficients to remove the unwanted portions. The signal scrubbing is performed in either the time domain or in the frequency domain. The method and apparatus are particularly advantageous to blood oximetry and pulserate measurements. In another embodiment, an estimate of the pulserate is obtained by applying a set of rules to a spectral transform of the scrubbed signal. In another embodiment, an estimate of the pulserate is obtained by transforming the scrubbed signal from a first spectral domain into a second spectral domain. The pulserate is found by identifying the largest spectral peak in the second spectral domain.

摘要翻译：一种用于分析被建模为包含期望和不期望的部分（例如噪声，FM和AM调制）的两个测量信号的方法和装置。系数根据根据本发明定义的模型关联两个信号。在一个实施例中，使用变换来评估两个测量信号的比率以找到适当的系数。然后将测量的信号馈送到信号洗涤器中，该信号洗涤器使用系数去除不需要的部分。信号擦除在时域或频域中进行。该方法和装置对于血氧饱和度测量和脉动测量是特别有利的。在另一个实施例中，通过将一组规则应用于经擦除的信号的频谱变换来获得脉冲发生器的估计。在另一个实施例中，通过将擦除的信号从第一光谱域变换成第二光谱域来获得脉冲发生器的估计。通过识别第二个光谱域中最大的光谱峰值来发现脉冲发生器。

摘要： An optical probe, which is particularly suited to reduce noise in measurements taken on an easily compressible material, such as a finger, a toe, a forehead, an earlobe, or a lip, measures characteristics of the material. A neonatal and adult disposable embodiment of the probe include adhesive coated surfaces to securely affix the probe onto the patient. In addition, the surface of the probe is specially constructed to minimize light piping effects. Furthermore, a flex circuit acts as a spring to absorb shock which may misalign the emitter and detector. One embodiment of the adult probe includes a cushioning pocket formed for a fingertip to align the probe and to absorb motion of the probe due to contact. The neonatal probe is formed with a unique V-configuration which provides multiple advantages.
