Described herein are multifunctional smart beds and methods of operating thereof. Specifically, a multifunctional smart bed comprises a controller, configured to receive input from various sensors (e.g., load cells positioned in bed legs, thermometers, and/or microphones) and/or user. These inputs are analyzed and used to control various bed components to improve the sleep quality, to monitor users' health, score couple's relationship, and the like. For example, these inputs may be used to control the firmness of different mattress portions, change orientations of the head, torso, and/or leg sections, adjust the light, and the like. In some examples, the smart bed generates a report indicating one or more sleep duration, sleep depth profile, sleep scope, heart rate, breath rate, environment conditions, couple's relationship, and the like. Furthermore, in some examples, a multifunctional smart bed is also configured to control external devices in the same environment, e.g., smart switches, smart thermostats.

System & Method for Measurement of Respiratory Rate and Tidal Volume Through Feature Analysis of Breath Sounds to Detect Disease State

A system and method using a microphone to collect sound data produced by a potential patient's respiration and speech. The system preferably uses a microphone on a portable electronic device—such as a smart phone. The analysis of the collected data is preferably performed locally—such as by a software application running on the smartphone. The software is used to analyze the data and therefore determine and track useful parameters such as respiration rate and respiratory tidal volume. The software also analyzes phonation patterns. Using the parameters, the inventive system can detect the onset of respiratory distress.
