Abstract: A predictive diagnostic system (10) for a distributed population of automated external defibrillator (AED) devices comprises a plurality of AEDs (12) and a remote service provider (RSP) computer (14) configured to receive and transmit information pertaining to periodic AED self-tests. Each AED (121 to 12N) is provided with a controller for testing a readiness of the AED according to a self-test protocol. The RSP computer (i) analyzes self-test result data that includes functional measurement values of the periodic self-tests and which includes data from at least one failed AED (12N-2 to 12N) of the plurality, (ii) identifies an indicator of an impending fault or failure predictive of an impending AED device fault or failure in at least one non-failed AED (124) based on the analyzed data, and (iii) remotely modifies the self-test protocol of a sub-set (124) of the plurality of AEDs, based on the indicator, to pre-empt an occurrence of a self-test failure in the AED devices of the sub-set.

Abstract: The subject invention is concerned with systems and methods advantageously applying finite element analysis to establish design rules for a highly sensitive piezo-resistive pressure sensor with an output that is high enough to be detectable by simple and inexpensive circuits and therefore ensure wearability. Four frequently reported micro-feature shapes in micro-patterned piezo-resistive sensors are provided, where the micro-dome and micro-pyramid yield the highest sensitivity. Investigations of different conductivity values of micro-patterned elastomers show that coating the elastomer with a conductive material (e.g., a metallic coating) leads to higher current response when compared to composited conductive elastomers. Advantageous geometric parameters and spatial configurations of micro-pyramid design of piezo-resistive sensors are provided.

Abstract: A system using combined electrocardiography (EKG) and photoplethysmography (PPG) sensing to assess intra-arterial fluid volume is described. The system uses averaging of similar pulses based on prior (n?1; n minus 1) R-to-R pulse wave duration, and prior-prior (n?2; n minus 2) R-to-R pulse wave duration, to determine a patient's fluid status and whether it is below or above optimal intravascular hydration.

Abstract: An apparatus for non-invasively measuring bio-information is provided. The apparatus for estimating bio-information may include a pulse wave sensor including a plurality of channels, and configured to measure pulse wave signals at a plurality of points of an object; and a processor configured to generate oscillograms corresponding to the plurality of channels based on the pulse wave signals measured by the plurality of channels; determine a channel, from among the plurality of channels, for estimating the bio-information based on the oscillograms; and estimate the bio-information based on an oscillogram of the channel.

Abstract: A system using combined electrocardiography (EKG) and photoplethysmography (PPG) sensing, to determine venous oxygen saturation is described. The system uses averaging of similar pulses based on Prior (or n?1) R-to-R pulse wave duration, and current (or n) R-to-R pulse wave duration for evaluation of the metabolic reserve and/or stress of the patient.
