Abstract: Aspects of the present disclosure are directed to a CPU and a memory circuit that has user-corresponding data stored on the memory circuit, and a platform over which a plurality of electrodes are interleaved, and configured for engaging the user. While the plurality of electrodes is concurrently contacting a limb or other extremity of the user, measurement signals are obtained from the plurality of electrodes. Based on a plurality of impedance-measurement signals being obtained from the electrodes, signals are generated that correspond to cardiovascular timings of the user. In such aspects of the present disclosure, pulse characteristic signals are determined based on the plurality of impedance-measurement signals. One of the pulse characteristic signals is extracted, and used as a timing reference to extract and process another pulse characteristic signal.

Abstract: Aspects of the present disclosure are directed toward obtaining a plurality of impedance-measurement signals while a set of at least three electrodes are concurrently contacting a user. Additionally, various aspects of the present disclosure include determining a plurality of pulse characteristic signals based on the plurality of impedance-measurement signals. One of the pulse characteristic signals is extracted from one of the impedance-measurement signals and is used as a timing reference to extract and process another of the pulse characteristic signals.

Abstract: Weighing scale apparatuses (devices and systems) and methods are implemented using a variety of biometric-based devices and methods. According to one such implementation, a weighing scale uses a base unit to integrate a support structure, a display, and circuitry to measure and determine the physiological parameters of the user, including a user-weight metric. The support structure includes a platform region that utilizes sensor circuitry to collect physiological data from the user, which is then processed by user-targeted circuitry to determine the physiological parameters (e.g., weight and heart-related measurements) of the user. Such parameters are then associated with the user and saved to a data-access circuit, and also forwarded to a display which communicates the physiological parameters among other information to the user through the platform region; the display encompassing substantially all of the platform region, including the region(s) upon which the user would stand for weight measurements.

Abstract: In accordance with embodiments of the present disclosure, a ballistocardiogram (BCG) sensor is used to detect heart and vascular characteristics of a user, and provide a BCG output indicative of the detected cardiovascular characteristics. The BCG output can be used for various purposes, such as detecting arterial aging. Secondary sensors can be used in conjunction with the BCG and can be used to determine the central arterial blood pressure, when used in conjunction with a peripheral blood pressure measurement.

Abstract: Characteristics of a user's heart are detected. In accordance with an example embodiment, a ballistocardiogram (BCG) sensor is used to detect heart characteristics of a user, and provide a BCG output indicative of the detected heart characteristics. The BCG output is further processed using data from one or more additional sensors, such as to reduce noise and/or otherwise process the BCG signal to characterize the user's heart function.

Abstract: An analyte is separated from a fluid sample by introducing the sample into a cartridge having a sample port and a first flow path extending from the sample port. The first flow path includes an extraction chamber containing a solid support for capturing the analyte from the sample. The cartridge has a second flow path for eluting the captured analyte from the extraction chamber, the second flow diverging from the first flow path after passing through the extraction chamber. The sample is forced to flow through the extraction chamber and into a waste chamber, thereby capturing the analyte with the solid support as the sample flows through the extraction chamber. The captured analyte is then eluted from the extraction chamber by forcing an elution fluid to flow through the extraction chamber and along the second flow path.

Abstract: In some embodiments, a wearable physiologic monitor comprises a mixed analog and digital application-specific integrated circuit (ASIC) including signal conditioning circuitry, an A/D converter, a real-time clock, and digital control logic. The signal conditioning circuitry includes analog amplification circuitry, analog (continuous-time or switched capacitor) filtering circuitry before the A/D converter, and in some embodiments digital (DSP) filtering circuitry after the A/D converter. The monitor includes sensors such as electrocardiogram (ECG) electrodes, accelerometers, and a temperature sensor, some of which may be integrated on the ASIC. The digital control logic receives digital physiologic data sampled at different rates, assembles the data into physiologic data packets, time-stamps at least some of the packets, and periodically stores the packets in a digital memory. The monitor may include a disposable patch including the ASIC, and a reusable, removable digital memory such as flash memory card.
