Embodiment

[0240] Figures 14A to 17B A further embodiment of a comparison between the uterine trace data and the output of the exemplary method 200 is shown. exist Figure 14A , 15A In each of , 16A and 17A, the uterine signal versus time is shown, with monitoring of maternal self-reported contractions by uterine tracings represented using vertical lines. exist Figure 17B , 15B In each of , 16B, and 17B, the filtered R-wave signals from each of the multiple channels are shown in different colors (e.g., similar to Figure 11B Graph shown in ), where the calculated normalized mean signal (e.g., similar to Figure 12A graph shown in ). Figure 14B , 15B , 16B, and 17B each with Figure 14A , 15A A corresponding one of , 16A and 17A is shown next to each other for comparison (eg, Figure 14A and 14B shows different data recorded for the same mother in the same time interval, for Figures 15A to 17B So on and so forth). as above reference Figure 12A and 12B As discussed, it ...

Abstract

A method includes receiving bio-potential inputs; generating signal channels from the bio-potential inputs; pre-processing data in the signal channels; extracting R-wave peaks from the pre-processed data; removing artifacts and outliers from the R-wave peaks; generating R-wave signal channels based on the R-wave peaks in the pre-processed signal channels; selecting two or more of the R-wave signal channels; and combining the selected two or more R-wave signal channels to produce an electrical uterine monitoring signal.

Description

[0001] Cross References to Related Applications [0002] This application is an International (PCT) application related to commonly owned, co-pending U.S. Provisional Patent Application No. 62 / 713,324, filed August 1, 2018, and entitled SYSTEMS AND METHODSFOR MATERNAL UTERINE ACTIVITY DETECTION and filed October 26, 2018 US Provisional Patent Application No. 62 / 751,011, entitled SYSTEMS AND METHODS FOR MATERNALUTERINE ACTIVITY DETECTION, was filed and claimed, the contents of both applications are hereby incorporated by reference in their entirety. technical field [0003] The present invention generally relates to monitoring expectant mothers. More specifically, the present invention relates to analyzing sensed bio-potential data to generate a computational representation of uterine activity, such as uterine contractions. Background technique [0004] Uterine contractions are brief processes during which the muscles of the uterus shorten and the space between muscle cells ...
