Publication number: 20160206245Abstract: Systems, methods, sensors, and software for providing enhanced measurement and correction of physiological data are provided herein. In one example, a capacitive sensor of a measurement system is positioned onto tissue of a patient. The capacitive sensor includes one or more conductive elements with associated gain properties that are positioned near optical sensor elements proximate to the tissue of the patient, the optical sensor elements positioned to measure a photoplethysmogram (PPG) for the tissue. The measurement system drives the capacitive sensor and measures capacitance signals associated with the capacitance sensor. The measurement system corrects for at least motion noise in the PPG using the capacitance signals.Type: ApplicationFiled: January 15, 2016Publication date: July 21, 2016Inventors: Eric Morland, Christopher J.

Publication number: 20160206247Abstract: Systems, methods, apparatuses, and software for providing enhanced measurement and correction of physiological data are provided herein. In a first example, a physiological measurement system is configured to obtain a measured photoplethysmogram (PPG) for a patient, and obtain a reference signal for the patient measured concurrent with the measured PPG, the reference signal including noise components related to at least motion of the patient. The physiological measurement system also is configured to determine a filtered PPG from the measured PPG using at least an adaptive filter with the reference signal to reduce noise components of the measured PPG, determine a final PPG by spectrally subtracting at least a portion of the noise components of the reference signal from the filtered PPG, and identify one or more physiological metrics of the patient based on the final PPG.Type: ApplicationFiled: January 15, 2016Publication date: July 21, 2016Inventors: Eric Morland, Clark R.

Publication number: 20150245782Abstract: Various methods and systems for the use of capacitance sensors within medical devices configured for patient monitoring are provided. The capacitance sensors are configured to measure a change in capacitance resulting from a material (e.g., human tissue, water, gel, cloth, etc.) placed near (e.g., close proximity to) the medical device and/or resulting from a material making physical contact with the medical device. In certain embodiments, the capacitance sensor may be utilized to detect whether one or more portions of the medical sensor are securely applied to the patient's tissue (e.g., sensor “on”) and/or may be utilized to detect whether one or more portions of the medical sensor fail to maintain secure contact with the patient's tissue (e.g., sensor “off”). Further, in certain embodiments, the capacitance sensor may be utilized to distinguish between one or more types of materials (e.g., human tissue, water-based materials, etc.).Type: ApplicationFiled: December 19, 2014Publication date: September 3, 2015Inventors: Eric Morland, Daniel Lisogurski, Christopher Meehan, Sarah Hayman, Darshan Iyer, Friso Schlottau
