    Abstract: A system is disclosed for detecting and calculating the level of ambient and/or environmental noise, such as electromagnetic interference generated by electric power lines, ambient lights, light dimmers, television or computer displays, power supplies or transformers, and medical equipment. In some embodiments, the system performs frequency analysis on the interference signal detected by light photodetectors and determines the power of the interference signal concentrated in the analyzed frequency bands. The worst-case interference level can be determined by selecting the maximum from the computed power values. In some embodiments, the determined interference signal power can be compared with the noise tolerance of a patient monitoring system configured to reliably and noninvasively detect physiological parameters of a user. The results of the comparison can be presented to the user audio-visually. In some embodiments, the system can be used to perform spot check measurements of electromagnetic interference.

    Abstract translation: 公开了一种用于检测和计算环境和/或环境噪声的水平的系统,例如由电力线,环境光,光调光器,电视或计算机显示器,电源或变压器和医疗设备产生的电磁干扰。 在一些实施例中,系统对由光检测器检测到的干扰信号进行频率分析,并确定集中在分析频带中的干扰信号的功率。 最坏情况的干扰电平可以通过从计算的功率值中选择最大值来确定。 在一些实施例中,所确定的干扰信号功率可以与被配置为可靠地和非侵入性地检测用户的生理参数的患者监视系统的噪声容限进行比较。 比较的结果可以直观地呈现给用户。 在一些实施例中,该系统可用于执行电磁干扰的抽查检查测量。

    Abstract: A physiological test credit method determines if test credits are available to the monitor and checks if a Wi-Fi connection is available. If test credits are less than a test credit threshold, the monitor connects to a test credit server, processes server commands so as to download test credits and disconnects from the server. In various embodiments, the monitor is challenged to break a server code, the server is challenged to break a monitor code. The server validates monitor serial codes, and saves monitor configuration parameters.
