Inan et al. (2015) — ballistocardiography and seismocardiography review (2014-10-07)

- disclosure: Inan OT, Migeotte P-F, Park K-S, Etemadi M, Tavakolian K, Casanella R, Zanetti J, Tank J, Funtova I, Prisk GK, Di Rienzo M. ‘Ballistocardiography and seismocardiography: a review of recent advances.’ IEEE Journal of Biomedical and Health Informatics 2015;19(4):1414-1427.
- ip status: public-domain
- sensors: sensor-accelerometer, sensor-piezoelectric
- algorithms: algo-hr, algo-hrv, algo-pwv-bp-estimation
- prior art notes: Reviews ballistocardiography (whole-body reaction force from cardiac ejection, measured at the seat/scale/bed) and seismocardiography (local chest vibration from cardiac motion, measured by accelerometers on the sternum) and their integration into bathroom scales, weighing chairs, beds, and chest patches — i.e. the mechanical-cardiac-signal route to heart rate, HRV, and cardiac-timing-interval / stroke-volume estimation. Prior art for claims reciting ‘measuring cardiac activity from a body-worn or support-mounted accelerometer/force sensor’, as both the BCG and SCG approaches and their wearable instantiations were collected and reviewed by 2015. Anchor for the BCG/SCG cross-cut.
VitalConnect VitalPatch (2016) — adhesive chest patch with single-lead ECG and multi-parameter monitoring (2016)
- id:
vitalconnect-vitalpatch-2016 - corpus: private
- form factor: patch
- creator: VitalConnect, Inc.
- disclosure: VitalConnect, Inc. ‘VitalPatch’ biosensor, FDA-cleared as a single-use adhesive chest patch with single-lead ECG, heart rate, heart-rate variability, respiratory rate, skin temperature, posture, activity, and fall detection, streamed wirelessly to a smartphone/relay; 7-day wear (later 14-day variants).
- ip status: patented
- sensors: sensor-ecg, sensor-accelerometer, sensor-skin-temperature
- algorithms: algo-hr, algo-hrv, algo-respiratory-rate, algo-activity-classification, algo-posture-detection, algo-fall-detection, algo-arrhythmia-classification
- prior art notes: Discloses a single-use adhesive chest patch deriving single-lead ECG, HR, HRV, respiratory rate, skin temperature, posture, activity, and falls in one body-worn unit, streamed wirelessly — i.e. a packed multi-parameter vital-signs patch. Anticipates multi-parameter ECG-patch claims combining any subset of those measurements in one adhesive form factor from 2016. Product-side anchor for the patch × multi-parameter-vitals cross-cut alongside [[fda-k113862-irhythm-zio-patch-2011]] (the AFib-focused variant).
Polar H10 (2017) — research-grade chest-strap ECG heart-rate sensor (2017-01)
- id:
polar-h10-chest-strap-2017 - corpus: private
- form factor: garment
- creator: Polar Electro Oy
- disclosure: Polar Electro Oy. ‘Polar H10’ chest heart-rate sensor, released 2017 — a chest strap with two dry electrodes deriving a single-lead ECG, computing R-R intervals and heart rate, with onboard 1-session memory, dual-broadcast (BLE + ANT+ + 5 kHz GymLink), an accelerometer (relative orientation), and well-documented R-R-interval accuracy (often used as a gold-standard reference for consumer wearables).
- ip status: patented
- sensors: sensor-ecg, sensor-accelerometer
- algorithms: algo-hr, algo-hrv, algo-arrhythmia-classification
- prior art notes: Discloses a chest strap with two dry electrodes deriving single-lead ECG, with on-strap R-R-interval computation, multi-protocol broadcast (BLE + ANT+ + the 5 kHz GymLink legacy band), and accelerometer-assisted noise rejection. Anticipates chest-strap-ECG claims combining ‘dry textile/elastic chest electrodes’, ‘on-strap derivation of R-R intervals and HR’, and ‘multi-protocol simultaneous wireless broadcast’ from 2017. Product-side anchor for the garment/patch × ECG strap cross-cut; refines [[polar-sport-tester-pe2000-1982]].
