Abstract: According to one configuration, a system includes sensor hardware and signal processor resource to monitor and analyze bio-media (such as blood and/or other matter) of a person under test. During operation, the sensor hardware monitors the bio-media of the person under test and produces an output. The monitored output (such as one or more signals) varies in magnitude based at least in part on person-induced movement. The signal processor resource analyzes the output produced by the sensor hardware. Based on the analysis, and detected variation in the output of the sensor hardware as caused by the person's movement, the signal processor resource produces a setting for a biometric parameter of interest associated with monitoring the bio-media. Note that the system as described herein can be used to measure different biometric parameters of interest such as venous blood oxygen content, vein stiffness, etc.

Abstract: The present disclosure describes an apparatus for determining the condition of a subject's heart. The apparatus includes a patch adhered to a chest of the subject, the patch further including at least one ultrasound sensor for directing an ultrasound beam to the subject's heart and receiving a reflection of the beam; control circuitry for generating data signals based on the beam reflection indicative of a distance of the heart from the ultrasound sensor; and a processing system for receiving the data signals from the control circuitry and processing the data signals to track movement of the subject's heart over time, wherein changes in the movement correlate to the subject's heart condition.

Abstract: There is disclosed herein examples of systems and methods for compressing a signal. Samples of the signal can be segmented and the samples within each of the segments can be averaged to produce a value that can represent the samples within the segment. The number of samples to average in each segment may be determined based on an error threshold, such that the number of samples being averaged can be maximized to produce less data to be transmitted while maintaining the representation of the samples within the error threshold. In some embodiments, a signal can be separated into a timing reference, a representative periodic function, and a highly compressible error signal. The error signal can be utilized for reproducing a representation of the signal.

Abstract: There is disclosed herein examples of systems and methods of processing captured heart sounds with frequency-dependent normalization. Based on an amount of attenuation of a first heart sound, a second heart sound can be normalized by modifying portions of the second heart sound by amounts determined based on frequencies of the portions. Accordingly, the systems and methods disclosed herein can result in different amounts of modification of different portions of the second heart sound based on the different frequencies of the portions.
