3 BEpatch: J peak detection
BCG J peak detection: Past: Modified Pan-Tompkins with ECG synchronization, correlation method Future: Blind segmentation method Bandpass: access rough shape Synchronization points: local max/min Extract cycle: based on sync points Detect HIJ complex source: Akhbardeh, A., Kaminsk, B., and Tavakolian, K. Bseg++: A modified blind segmentation method for ballistocardiogram cycle extraction. Proceedings of the 29th EMBS IEEE Conference. p

13 Conclusion BEpatch receives a lot more 1Hz signals (as seen in all measurements except 5), there’s really no pattern in which signal is second most dominant The dominant signal in BCG is 4.2Hz, and second dominant is 5.8Hz BEpatch sees a lot of signals beyond 10Hz BEpatch sees a lot of 4.2Hz over heart and below heart (?), but the peaks are more defined when placed over chest

14 BEpatch vs BCG (BMSIL) Me and Saram have similar FFTs using BMSIL BCG, but my signal is noisy on BEpatch
