A system is provided for separating a plasma-containing fluid into separated plasma and a concentrated fluid. The system cooperates with a fluid flow circuit including a fluid separation chamber and a plasma outlet line associated therewith for removing separated plasma from the fluid separation chamber. The system includes an optical sensor assembly to monitor the contents of the plasma outlet line and produce an output indicative of the concentration of free plasma hemoglobin in the plasma outlet line. A controller of the system calculates the amount of free plasma hemoglobin in at least a portion of the concentrated fluid based at least in part on the output of the optical sensor assembly. The controller may periodically calibrate the optical sensor assembly by determining an instrument-specific correlation between optic output and free hemoglobin concentration and comparing it to experimentally determined data to ensure continued reliability of the optical sensor assembly.

A biosensor includes an optical circuit that obtains a plurality of photoplethysmography (PPG) signals from light at different wavelengths that is reflected from or transmitted through tissue of a user. A processing circuit determines a measurement value for a nitric oxide (NO) level in blood flow using first and second PPG signals and determines an insulin response from caloric intake using the measurement value for the NO level in blood flow. The first PPG signal is obtained from light at a wavelength having a high absorption coefficient for NO in blood flow and the second PPG signal is obtained from light at a second wavelength having a low absorption coefficient for NO in blood flow. The processing circuit also determines one or more phases of digestion using at least one or more of the plurality of PPG signals.

A method for determining and responding in real-time to an increased risk of death relating to a patient with epilepsy is provided. The method includes receiving cardiac data and determining a cardiac index based upon the cardiac data. The method includes determining an increased risk of death associated with epilepsy if the indices are extreme, issuing a warning of the increased risk of death and logging information related to the increased risk of death. Also presented is a second method for determining and responding in real-time to an increased risk of death relating to a patient with epilepsy comprising receiving at least one of arousal data, responsiveness data or awareness data and determining an arousal index, a responsiveness index or an awareness index, where the indices are based on arousal data, responsiveness data or awareness data respectively. The second method includes determining an increased risk of death related to epilepsy if indices are extreme values, issuing a warning of the increased risk of death and logging information related to the increased risk of death. A computer readable program storage device is also provided. Also provided is a method for receiving body data, determining a cardiac, an arousal, a responsiveness, or a kinetic index, determining an increased or increasing risk of death over a first time window relating to a patient with epilepsy and issuing a warning and logging relevant information.

The present disclosure presents systems, apparatuses, and methods of evaluating air quality sensor data. In this regard, a method comprises receiving air quality sensor data from a plurality of portable smart air quality measurement system (SAQMS) communication devices from a plurality of citizens in a geographic location; receiving air quality sensor data from an air quality measurement and calibration (AQMC) station in the geographic location; determining a level of resolution for one or more sensors of a portable SAQMS communication device at a central evaluation and measurement service; correcting air quality data received from the portable SAQMS communication device to compensate for the determined level of resolution at the central evaluation and measurement service; and generating a map of air quality data based on at least the corrected air quality data of the portable SAQMS communication device and a plurality of other portable SAQMS communication devices.

Release of a neurological drug in a targeted region of a subject's brain by a drug delivery system (DDS) is intentionally caused by the subject watching or interacting with an audio/video-based task on an electronic display. The DDS is calibrated to release the neurological drug based on a particular pH, lactate level, blood flow, temperature, magnetic field, specific molecules released by brain cells, or other physiological factors within the target region. The interactive task produces the physiological factors in the brain in specific areas of pathology for which the drug is prescribed, and limits drug delivery at areas unaffected by illness where it could disrupt normal function, causing problematic side effects and preventing dose levels optimal for target impact. Feedback from the interactive task and associated cognitive probes also can adapt the interactive task or suggest new pharmacologic agents as the degree or primary focus of brain pathology changes during the course of treatment.
