A wearable system configured to collect thermal measurements related to respiration. The system includes a frame configured to be worn on a user's head, and at least one non-contact thermal camera (e.g., thermopile or microbolometer based sensor). The thermal camera is small and lightweight, physically coupled to the frame, located close to the user's face, does not occlude any of the user's mouth and nostrils, and is configured to take thermal measurements of: a portion of the right side of the user's upper lip, a portion of the left side of the user's upper lip, and a portion of the user's mouth. The thermal measurements are forwarded to a computer that calculates breathing related parameters, such as breathing rate, an extent to which the breathing was done through the mouth, an extent to which the breathing was done through the nostrils, and ratio between exhaling and inhaling durations.

The present invention relates to a method for screening cardiac conditions of a patient, the method comprising the following steps: calculating (S1) a cardiac risk value based on therapy sensor data by means of a first level of a multi-level procedure, wherein the therapy sensor data is provided from a first data source as sensor data during a therapy of the patient; and refining (S2) the calculated cardiac risk value based on survey data and/or device data by means of a second level of a multi-level procedure to provide a refined cardiac risk value, wherein the survey data and/or the device data is provided from a second data source by incremental data gathering.

An apnea analysis system may include a photoplethysmographic (PPG) sub-system, a breath detection sub-system, and an apnea analysis module. An apnea analysis system includes a photoplethysmographic (PPG) sub-system, a breath detection sub-system, and an apnea analysis module. The PPG sub-system is configured to be operatively connected to an individual and output a PPG signal from the individual. The breath detection sub-system is configured to be operatively connected to the individual and output a breath signal from the individual. The apnea analysis module is in communication with the PPG sub-system and the breath detection sub-system. The apnea analysis module analyzes the breath signal and a respiratory component of the PPG signal and, based on the analysis, identifies a presence of apnea, differentiates between obstructive apnea and central apnea, and provides an indication of the identified apnea.

A sexual stimulation device for applying stimulus to an erogenous zone of the human body. The sexual stimulation device has a body and an interchangeable head that can be interchangeably coupled to the body. The body has a motor. The interchangeable head has a stimulation surface. A kit is also provided having two such bodies and four interchangeable heads. Each of the four interchangeable heads has a different stimulation surface.

An electronic stethoscope includes an acoustic sensor assembly having a first microphone to detect biological sounds within a body, a detection system in communication with the first microphone to receive an auscultation signal from the first microphone, the auscultation signal including information of the biological sounds detected by the first microphone. The stethoscope also includes a second microphone in communication with the detection system to detect noise from an environment of the body. The detection system receives a noise signal from the second microphone, and provides a resultant signal based on the auscultation signal and the noise signal. The detection system subtracts information from the auscultation signal to produce the resultant signal, where the subtracted information is based on the noise signal such that the subtracted information is based more on higher frequency ranges of the noise signal compared to a lower frequency range corresponding to the biological sounds.

An embodiment of the invention provides a method of diagnosing obstructive sleep apnea, the method comprising: acquiring a sleep sound signal comprising sounds made by a person during sleep; detecting a plurality of snore sounds in the sleep sound signal; determining a set of mel-frequency cepstral coefficients for each of the snore sounds; determining a characterizing feature for the sleep sound signal responsive to a sum of the variances of the cepstral coefficients; and using the characterizing feature to diagnose obstructive sleep apnea in the person.

Provided herein are systems, devices, and methods to measure auditory signals from a subject to determine a state of a subject. The auditory signals measured may provide a tool to monitor the development of disease state(s) or abnormal physiologic conditions (e.g., wheezing, fluid accumulation, abnormal heart murmur or rhythm, etc).

A garment comprising a central portion including a plurality of electrocardiogram leads, a plurality of auscultation acoustic sensor devices, a flexible respiratory sensor located so that it substantially circumscribes the garment, one or more blood pressure cuff portions located on an at least one arm portion of the garment, wherein the cuff portions are adapted to be loosened and/or tightened and a hardware device for sending and receiving signals via wired or wireless communication.

Systems and methods for monitoring patients with respiratory diseases are described. A system may include a sensor circuit configured to sense one or more physiological signals indicative of respiratory sounds, and a spectral analyzer to generate first and second spectral contents at respective first and second frequency bands. The system may produce a respiratory anomaly indicator using the first and second spectral contents, or additionally with other physiological parameters. The system may detect an onset or progression of a target respiratory condition such as asthma or chronic obstructive pulmonary disease using the respiratory anomaly indicator, or to trigger or adjust a therapy.

Systems and methods for monitoring patients with respiratory diseases are described. A system may include a sensor circuit to sense a respiration signal and at least one hemodynamic signal. The system may detect a specified respiratory phase from the respiration signal, and generate from the hemodynamic signal one or more signal metrics that are correlative to at least one of a systolic blood pressure, a blood volume, or a cardiac dimension. The system may detect a restrictive or obstructive respiratory condition when the hemodynamic signal metric indicates hemodynamic deterioration during a specified respiratory phase. The system may additionally classify the detected restrictive or obstructive respiratory condition into one of two or more categories, and deliver a therapy based on the detection or the classification.
