A wireless wearable sensor device, system, method, and non-transitory computer readable medium for screening for structural heart disease based on electrocardiogram, phonocardiogram, and/or accelerometer signals on a patient's skin surface.

Screening device, method, and system for structural heart disease

The present application relates to a device, system, and method for determining patient body temperature based on a multi-modal wearable biosensor applied to the surface of the body that measures multiple physiological, physical, and skin-surface/microclimatic thermal parameters, derives additional instantaneous parameters, learns contextual parameters based on temporal dynamics, and employs ensemble model fusion method to estimate core body temperature.

Method and system for body temperature estimation using a wearable biosensor

A method and system for detecting pacing pulses originating from implanted pacemaker using surface Electrocardiogram (ECG) signals measured at a relatively low sampling rate and also rejecting the pacing artifacts from the recorded surface ECG signals.

Method and system for pacing pulse detection and pacing artifact rejection

Various methods and systems are related to pulse-based automatic gain control. In one example, pulse-based automatic gain control (AGC) includes a variable gain amplifier (VGA) configured to amplify an analog input signal to generate an analog output signal based upon an amplification control signal; an integrate-and-fire (IF) sampler configured to generate a pulse train corresponding to the analog output signal; and a gain adjustment configured to generate the amplification control signal based upon a comparison of time between pulses of the pulse train to a reference time. In another example, a method includes determining time between pulses of a pulse train corresponding to an analog output signal from a VGA; generating an amplification control signal based upon a comparison of the time between pulses of the pulse train to a reference time; and adjusting amplification of the VGA in response to the amplification control signal.

Pulse based automatic gain control for analog and pulse domain regulation

Various examples of devices, methods and systems related to pulse based arithmetic units. In one example, a pulse domain device includes an augend area calculator to provide an augend area output for an augend pulse train; an addend area calculator to provide an addend area output for an addend pulse train; a resultant sum area (RSA) decoder to provide a RSA output using the augend and addend area outputs; and a pulse timing calculator to provide RSA output pulse timing. In another example, a pulse domain device includes a multiplicand area calculator to provide an multiplicand area output for a multiplicand pulse train; a multiplier area calculator to provide a multiplier area output for a multiplier pulse train; a resultant product area (RPA) decoder to provide a RPA output using the multiplicand and multiplier area outputs; and a pulse timing calculator to provide RPA output pulse timing.

Pulsed based arithmetic units

Various examples are provided for automation of QRS detection. In one example, among others, a system includes an integrate and fire (IF) sampler that can generate an IF pulse train from an analog input signal, and decision logic circuitry that can determine whether a QRS complex waveform is present in a pulse segment of the IF pulse train. In another example, a method includes generating an integrate and fire (IF) pulse train from an analog input signal, identifying a pulse segment of the IF pulse train, and determining whether a QRS waveform is present in the pulse segment based at least in part upon attributes associated with the pulse segment.
