Techniques for determining pulse transit time (PTT) and blood pressure measurements based on stethoscope data are provided. In one example, a system comprises a stethoscope component that monitors a heart and generates stethoscope data representative of a sound wave generated by the heart. The system can further comprise an analysis component that receives the stethoscope data and receives, from a photoplethysmography (PPG) component that monitors an extremity, PPG data representative of a pulse wave at the extremity. The analysis component can determine, based on the stethoscope data, a first time corresponding to closure of a tricuspid valve of the heart and can determine a PTT as a function of the first time and a second time corresponding to the pulse wave at the extremity that is determined based on the PPG data. Blood pressure measurements can be obtained from algorithms with the inputs of PTT or times determined based on the PPG data.

Determining blood pulse characteristics based on stethoscope data

An apparatus includes a wearable sensor structure that includes multiple individual sensor units placed in a row. Each individual sensor unit includes a first portion to contact a surface of skin under which arteries and/or veins are to be located, and a second portion that contacts the first portion and is configured to have a capacitance. The first and second portions are configured to create a capacitance change in response to a squeezing or bending between the first portion and a fixed part of the second portion caused by a pulse pressure and release of the pulse pressure. The apparatus includes circuitry configured to measure waveforms for the individual sensor units. Each waveform captures the capacitance change for its corresponding individual sensor unit. The apparatus includes a wireless interface configured to transmit the waveforms. A computing system is also disclosed that analyzes the waveforms and can provide alerts based thereon.

Layered and multi-sectional pulse wave sensors and use thereof

Embodiments of the invention are directed to a photoplethysmogram (PPG) structure that includes a wearable component and a network of PPG sensors physically coupled to the wearable component. Each PPG sensor of the network includes a housing, a first light source and a light detector. The first light source is positioned in or on the housing such that, when the housing is positioned on a surface, the housing positions an illuminating surface of the first light source at a predetermined first-light-source angle with respect to the surface.

Wearable reflectance-mode PPG sensor network having improved detected signal strength

A wearable patch system includes an electrocardiogram (ECG) sensor having electrodes configured to contact a subject. An electronic stethoscope has a diaphragm structure responsive to sounds from the subject. The ECG sensor and the electronic stethoscope are co-located to measure respective parameters concurrently from a same position. A housing is configured to support the diaphragm structure and the electrodes. The housing includes a mechanical interface configured to mount on the subject. A communications circuit is disposed on or in the housing to communicate with a remote component.

Combined wearable electrocardiogram and electronic stethoscope

An approach to provide an electronic assembly process that includes receiving at least one electronic assembly after a solder reflow process using a Sn-containing solder and a water-soluble flux. The approach includes baking the at least one electronic assembly in an oxygen containing environment and, then cleaning the at least one electronic assembly in an aqueous cleaning process.

Enhanced cleaning for water-soluble flux soldering

Systems and methods for monitoring body mounted/implanted sensors in combination with environmental sensors and sensors attached to person's medical/sports equipment. Data indicating a plurality of measured quantities associated with movement of a person at a time point is received. Each measured quantity within the plurality of measured quantities having been determined by a respective sensor attached to a respective location on the person or the person's environment or the person's medical/sports equipment. At least one characteristic of the person associated with the time point is determined based on analyzing the plurality of measured quantities. The at least one characteristic is stored. Recommendations for the person are determined based upon the characteristics, and a report comprising the recommendations is provided.

Wearable sensor monitoring and data analysis

An apparatus includes one or more memories storing computer readable code and processor(s). The processor(s), in response to loading and executing the computer readable code, cause the apparatus to perform operations including receiving electrocardiogram data from an electrocardiogram sensor. The electrocardiogram data includes data from an electrocardiogram from a person. The operations also include receiving pulse wave data from one or more pulse wave pressure sensors. The pulse wave data includes data from one or more pulse waves from the person. The operations further include determining blood pressure using the electrocardiogram data or the pulse wave data from the chest and the pulse wave data from the wrist or finger, and outputting an indication of the blood pressure. Another apparatus uses pulse wave data from two pulse wave sensors (e.g., pulse wave pressure sensor(s) and/or PPG sensor(s)) and blood pressure determinations are made using these pulse wave data.

Wearable blood pressure monitoring system

A flux formulation includes an activator and a protic solvent. The activator may be glutaric acid, levulinic acid, 2-ketobutyric acid, 2-oxovaleric acid, or mixtures thereof. Suitable protic solvents include alkanediol, alkoxy propanol and alkoxy ethanol. The flux formulation may be a no-clean flux formulation that may be used in the soldering of electronic circuit board assemblies, for example, in conjunction with a support fixture having a planar back surface that minimizes vibrations during processing that might otherwise cause misalignment between a chip and a substrate prior to solder reflow.

No clean flux composition and methods for use thereof

In accordance with the example embodiments of the invention there is at least a method and apparatus to perform receiving, with at least one diaphragm of a device placed on a skin of a living body of a human being or animal, acoustic data of the living body; determining digitized data from the acoustic data of the living body; and sending the digitized data towards an analytics system for a medical diagnosis associated with the living body; determining a relationship between the digitized data and health conditions of the human being or animal; and applying the relationship to a diagnosis of the health conditions of the human being or animal.
