摘要： :A pregnancy support system is provided for identifying potentially high-risk combinations of pregnancy-related factors such as symptoms. A categorization, such as a ranking, comparison or clustering of factors, provided by a health care professional, is received that may apply to a pregnant woman, e.g. symptoms they may report. A model is then built for identifying potentially high-risk combinations of pregnancy-related factors based on the received categorization of factors. Factors that apply to the pregnant woman are obtained, e.g. symptoms are reported by the pregnant woman, and they are applied to the model to determine and facilitate taking the appropriate course of action. This provides an automated analysis of pregnancy-related factors.

摘要： The present disclosure pertains to a system configured to detect slow wave sleep and/or non-slow wave sleep in a subject during a sleep session based on a predicted onset time of slow wave sleep and/or a predicted end time of slow wave sleep that is determined based on changes in cardiorespiratory parameters of the subject. Cardiorespiratory parameters in a subject typically begin to change before transitions between non-slow wave sleep and slow wave sleep. Predicting this time delay between the changes in the cardiorespiratory parameters and the onset and/or end of slow wave sleep facilitates better (e.g., more sensitive and/or more accurate) determination of slow wave sleep and/or non-slow wave sleep.
摘要翻译：本公开涉及一种系统，其被配置为基于慢波睡眠的预测开始时间和/或慢波睡眠的预测结束时间来在睡眠会话期间检测受试者中的慢波睡眠和/或非慢波睡眠，是基于受试者的心肺参数变化而确定的。受试者中的心肺参数通常在非慢波睡眠与慢波睡眠之间的转变之前开始改变。预测心肺参数的变化与慢波睡眠的发作和/或结束之间的这种时间延迟有助于更好地（例如，更灵敏和/或更准确）确定慢波睡眠和/或非慢波睡眠。

摘要： An actigraphy method includes receiving a physiological parameter signal as a function of time for a physiological parameter other than body motion (such as electrocardiography or a respiration monitor), computing a body motion artifact (BMA) signal as a function of time from the physiological parameter signal (for example, using a local signal power signal, a local variance signal, a short-time Fourier transform, or a wavelet transform over epochs of duration on order a few minutes or less), and computing an actigraphy signal as a function of time from the BMA signal, for example by applying a linear transform to the BMA signal and optionally applying filtering such as median removal and/or high-pass filtering.

摘要： A planning system is provided for planning breast feeding or milk expression. An input receives first milk flow information from breast pumping sessions and second milk flow information from breast feeding sessions. The first and second milk flow information are processed to derive a schedule, wherein the schedule specifies a combination of future breast pumping and breast feeding sessions. In this way, the system assists a mother in planning her milk production routine to best fit with her schedule as well as providing the best nutrition for the infant.

摘要： A method for processing health information includes receiving signals from sensors in a sleep mat, determining values of one or more features based on the sensor signals, calculating metrics for the sensors based on the feature values, selecting one of the sensors in the sleep mat based on the metrics, and determining presence of a subject based on the selected sensor signals. Another method includes receiving signals from first sensors and second sensors in a sleep mat, calculating metrics based on the signals from the first and second sensors, selecting one of the first sensors and one of the second sensors based on the metrics, and classifying sleep states based on signals from the selected one of the first sensors and the selected one of the second sensors. The first sensors may have a first gain and the second sensors may have a second gain.

摘要： For the purpose of obtaining information about a person's sleep and wake states, an arrangement (100) comprising a video camera (10) and a processing unit (20) is used. The video camera (10) serves for capturing a sequence of video frames during a time period, and the processing unit (20) is configured to process video frames provided by the video camera (10) and to provide output representative of the person's sleep and wake states during the time period. In particular, the processing unit (20) is configured to execute an algorithm according to which (i) a motion value-time relation, (ii) sets of features relating to respective epochs in the motion value-time relation and (iii) classifiers of the respective epochs are determined, wherein the algorithm is further configured to apply an adaptive prior probability determined for the particular person in dependence of the motion values of the respective epochs to the classifiers.

摘要： The present disclosure pertains to a system configured to determine one or more parameters based on cardiorespiratory information from a subject and determine sleep stage classifications based on a discriminative undirected probabilistic graphical model such as Conditional Random Fields using the determined parameters. The system is advantageous because sleep is a structured process in which parameters determined for individual epochs are not independent over time and the system determines the sleep stage classifications based on parameters determined for a current epoch, determined relationships between parameters, sleep stage classifications determined for previous epochs, and/or other information. The system does not assume that determined parameters are discriminative during an entire sleep stage, but may be indicative of a sleep stage transition alone. In some embodiments, the system comprises one or more sensors, one or more physical computer processors, electronic storage, and a user interface.
摘要翻译：本公开涉及一种被配置为基于来自受试者的心肺呼吸信息确定一个或多个参数并基于使用所确定的参数的判别无向概率图形模型（例如条件随机场）来确定睡眠阶段分类的系统。该系统是有利的，因为睡眠是一种结构化过程，其中为每个时期确定的参数在时间上不是独立的，并且系统基于为当前时期确定的参数确定睡眠阶段分类，确定参数之间的关系，为先前确定的睡眠阶段分类时代和/或其他信息。该系统不假定所确定的参数在整个睡眠阶段期间是歧视的，而是可以单独指示睡眠阶段转换。在一些实施例中，系统包括一个或多个传感器，一个或多个物理计算机处理器，电子存储器和用户接口。

摘要： The present disclosure pertains to a system (10) configured to determine spectral boundaries (216, 218) for sleep stage classification in a subject (12). The spectral boundaries may be customized and used for sleep stage classification in an individual subject. Spectral boundaries determined by the system that are customized for the subject may facilitate sleep stage classification with higher accuracy relative to classifications made based on static, fixed spectral boundaries that are not unique to the subject. In some implementations, the system comprises one or more of a sensor (16), a processor (20), electronic storage (22), a user interface (24), and/or other components.
