Systems and methods for measuring hemodynamic parameters with wearable cardiovascular sensing. An apparatus can include one or more sensors configured to measure an electrocardiogram signal of a user and one or more seismocardiogram (SCG) signals of the user, a memory and a processing system including one or more processors operatively coupled to the memory and the one or more sensors, and configured to receive the electrocardiogram and one or more SCG signals, and generate an assessment of heart health by determining one or more hemodynamic parameters based on the signals. The invention further includes a method for non-invasively monitoring heart health of a user including receiving an electrocardiogram signal from a first sensor of a wearable device, receiving one or more SCG signals from a second sensor of the wearable device, and generating the assessment of the heart health of the user by determining the one or more hemodynamic parameters.

Systems and methods for measuring hemodynamic parameters with wearable cardiovascular sensing

A bio-vibration device for use by a user having a finger for sensing vibration signals in an individual includes a finger coupler device, a vibration sensor and a communications circuit. The vibration sensor is affixed to the finger coupler device and is configured to be pressed against a selected site of the individual so as to sense a vibration signal therefrom. The communications circuit is responsive to the vibration sensor and is configured to transmit the vibration signal to a remote device.

Glove-based form factor for bio-acoustical sensing

As an IV infiltration occurs and fluid leaks into surrounding tissues, several physiological changes are expected locally. The systems and methods described herein provide a scalable automated IV infiltration detection device to provide medical staff an early warning of a possible infiltration such that they can respond accordingly. The systems and methods capture the physiological state of the user at or around a peripheral catheter insertion site by incorporating one or more modalities of wearable sensing, processing the data collected from these wearable sensors, detecting the presence of extravascular fluid, and providing an indication to a medical professional.

Systems and methods of IV infiltration detection

A method including receiving sound data captured by a wearable device of the user, the sound data indicative of contact between a first portion of the user wearing the wearable device and a second portion of the user wearing the wearable device; receiving motion data captured by the wearable device of the user, the motion data indicative of at least a movement of the first portion of the user wearing the wearable device; and determining, by a processor, based at least in part on the sound data and the motion data, a user input associated with the contact between a first portion of the user wearing the wearable device and a second portion of the user wearing the wearable device and the movement of the first portion of the user wearing the wearable device.

Systems, methods and devices for gesture recognition

A portable electronic device including: a plurality of sensors configured to generate, in response to a first contact with a body of a user in a vicinity of the portable electronic device, one or more first input signals; a microprocessor; and a memory having stored thereon instructions that, when executed by the microprocessor, control the microprocessor to execute, in response to an analysis of the one or more first input signals indicating that the first contact corresponds to a first gesture, and by the microprocessor, a first command corresponding to the first gesture.

Electronic device and method of controlling same

A method and apparatus for monitoring arterial properties, including systolic and diastolic pressure levels, of a subject is provided, in which a hardware processor receives and analyzes ballistocardiogram (BCG) data of the subject. A non-transient computer readable medium, accessible by the hardware processor, contains instructions that, when executed by the hardware processor, identify features of the BCG waveform and determine the arterial properties therefrom. For example, a diastolic pressure level may be determined from a time interval between the 'I' and 'J' peaks of the waveform and a systolic pressure level determined from the amplitude difference between the &#x2018;J&#x2019; and &#x2018;K&#x2019; peaks of the waveform in combination with the &#x2018;I-J&#x2019; time interval or amplitude difference. A physical mechanism for the BCG data is disclosed that enables other arterial properties of the subject to be determined from the BCG data alone or from the BCG data in combination with other measurements.

Monitor for blood pressure and other arterial properties

Multi-modal sensing relating to joint acoustic emission and joint bioimpedance. Custom-design analog electronics and electrodes provide high resolution sensing of bioimpedance, microphones and their front-end electronics for capturing sound signals from the joints, rate sensors for identifying joint motions (linear and rotational), and a processor unit for interpretation of the signals. These components are packed into a wearable form factor, which also encapsulates the hardware required to minimize the negative effects of motion artifacts on the signals.

Wearable technologies for joint health assessment

A wearable system and method for providing BCG data from a user including a wearable sensor configured to receive cardiogenic surface vibration waveforms, a calibrating sensor configured to receive cardiogenic center-of-mass (COM) vibration waveforms, and a processor configured to use the COM vibration waveforms as a template for modifying the surface vibration waveforms to provide health-related outputs. A systematic approach for elucidating the relationship between surface vibrations of the body in the head-to-foot direction from the wearable sensor, and the movements of the whole body as measured by the calibrating sensor is disclosed. Additionally, a methodology for converting the wearable acceleration signals to BCG signals such that the same analysis and interpretation tools can be used for both measurements is presented. High-resolution measurements of the surface accelerations of the body related to the heartbeat with a low weight accelerometer will minimally load the measurement in the transverse direction.
