Abstract: Embodiments of the disclosure provide a method for aggregating and providing health data records to an electronic device. The method is performed by a server that includes a processor and a non-transitory computer readable medium with processor-executable instructions stored thereon. When the instructions are executed by the processor, the server performs the method including: (a) receiving collected data from one or more client devices, the collected data comprising health related data including at least one of step count data, heart rate data, sleep sensor data; (b) extracting metadata from the collected data; (c) pseudonymizing the collected data; (d) categorizing the collected data using the extracted metadata and enterprise ontology of the server; and (e) storing the collected data.

Abstract: A method of integrating data across multiple data stores is provided. The method includes ingesting diverse data from multiple data sources and reconciling the ingested diverse data by updating semantic models based on the ingested diverse data. The method further includes storing the ingested diverse data based on one or more classification of the data sources according to the semantic models and automatically generating scalable service endpoints that are semantically consistent according to the classification of the data sources. The generated scalable service endpoints are application programming interfaces. The method also includes determining a protocol based on the scalable service endpoints in response to receiving a call from the one or more recipient systems and responding to the call from the one or more recipient systems by providing data in the classification of the data sources.

Abstract: Accurately measuring bio-impedance is important for sensing properties of the body. Unfortunately, contact impedances can significantly degrade the accuracy of bio-impedance measurements. To address this issue, a method is provided for estimating an impedance matrix of parasitic network disposed between a first network and a second network of a bio-impedance measurement system, the method comprising determining an impedance matrix for the first network (ZMUX) based on an impedance matrix for the second network (ZLOAD) for at least one known load condition; fitting ZMUX values for ZLOAD for the at least one known load condition to estimate parameters of the impedance matrix of the intervening network.

Abstract: The long-lived and recently modified (LLRM) partitioning is a system and method for partitioning slowly changing aged data for a given year into one long-lived partition (LLP) and multiple recently modified partitions (RMP) where the RMP corresponds to a time period of a first time granularity. Each record has a start and end time to indicate its lifetime. A record in a RMP is modified at a timepoint corresponding to the time period of a RMP. RMP records can be sampled every second, minute, hour or day. The LLP holds records whose lifetime is greater than the time period of a first time granularity. Queries pertaining to a given timepoint is performed on data that is a union of the LLP and the RMP pertaining to that timepoint instead of the unpartitioned table thus leading to shorter query processing time and better utilization of memory storage.

Abstract: Determining bio-impedance of a body, or portion thereof, of a subject has been utilized for determining health characteristics (such as heart conditions) of the subject. The systems and procedures described herein may provide for correction and/or compensation for electrode contact impedance and for accurately determining bio-impedance. The system may take into account impedance sensitivity and/or frequency sensitivity when performing the bio-impedance determination to improve the bio-impedance determination.

Abstract: A method for detecting allergic reaction and alerting a guardian device includes registering a wearable device to associate the wearable device with the guardian device. The wearable device then monitors vital signs to determine whether the vital signs are within an acceptable range. Based on the vital signs being outside the acceptable range, the wearable device sends an alert to the guardian device and determines whether a confirmation signal is received from the guardian device.

Abstract: Techniques for improving efficiency of a switched-capacitor voltage regulator are provided. In an example, a switched-capacitor voltage regulator can include a switched-capacitor network having multiple gain configurations, a clock configured to switch capacitors of the switched-capacitor network between a charge state and a discharge state to provide a scaled output voltage, and a controller configured to select a capacitor configuration associated with a gain of the multiple gain configurations to provide the scaled output voltage within a desired output voltage range while continuously switching the capacitor configuration, and to interrupt switching of the capacitor configuration to permit an output voltage of the switched-capacitor voltage regulator to fall below the scaled output voltage but to remain above a lower limit of the desired output voltage range to save power by reducing losses due to the switching.

Abstract: Methods, systems and circuits for controlling the power available to the load, by reducing the power available to the load, and additionally or alternatively, limiting the current available by pre-establishing a maximum reference current. The reference current is compared to the actual or estimated current drawn by the load or part of the load. The comparison result is used to control a device or switch which disconnects the power supply or power supply regulator, whether connected directly to the load or connected via voltage dropping device, to one or more or a plurality of the load blocks when the maximum current is exceeded.
