In a first aspect, a method of controlling an appliance is provided that includes (1) employing a wearable monitor to detect a biometric parameter of a user; (2) communicating biometric parameter information from the wearable monitor toluet a mobile telephone of the user; (3) determining if the biometric parameter information indicates that a value of the biometric parameter has crossed a predetermined threshold; and (4) if the value of the biometric parameter has crossed the predetermined threshold, employing the mobile telephone to direct an appliance to change between a first operating condition and a second operating condition. Numerous other aspects are provided.

A portable system is provided for measuring an analyte, such as acetone, in the breath or other bodily fluid of a user. The system includes a portable measurement device that analyzes fluid samples and generates corresponding measurements. The portable measurement device communicates with an application which runs on a smartphone or other mobile device of the user. The application tracks, and generates graphs of, the measurements, and may include various features for facilitating the analysis of the measurements.

In a handheld device for determining heartbeat/heart rhythm of a user, a method is provided for providing spoken instructions for the user of the device. The method comprises obtaining, over time, via an optical sensor like a camera, a data signal and providing the data signal to an electronic data processor. In the electronic data the processor, determining, based on the signal, a quality factor for the signal. In the electronic data processor, an algorithm is executed for determining a heartbeat using data comprised by the data signal as input. The electronic data processor looks up, from an electronic memory, at least one audio-visual data file comprising data representing audio-visual feedback instructions, based on at least one of the quality factor and the outcome of the execution of the algorithm. A speaker is used to reproduce the audio-visual feedback instructions and aid the user in device placement.

A thermal image analyzer includes a processor to receive a thermal image from at least one portable electronic device, with the thermal image being of an anatomical area of a patient, and determine an assessment on vascular health of the patient based on comparing the thermal image to a database of thermal images. The processor transmits the assessment in real-time to the at least one portable electronic device.

The present disclosure describes systems and methods for assessing heart and respiratory disorders in a patient using a video analysis tool to analyze video data taken of the patients neck region. The video analysis tool allows for an accurate, objective assessment of the patient. In some aspects of the present disclosure, a clinician may capture video data of the patients neck region and run the video analysis tool. Additionally or alternatively, the system may be implemented remotely whereby the video analysis tool may be executed remotely from the video recording device. The video analysis tool extracts pulsatile signals in the neck region from the video data and determines pulsatile signals of interest for assessing heart and respiratory disorders in the patient. The video analysis tool generates assessment data based on the pulsatile signals of interest.

Systems and methods for diurnal curve generations, tracking, and analysis are provided. Based on a user's demographic, or a user's baseline diurnal curve, insights into a user's temperature reading can be produced. Such insights can be used to, for example, assess the probability that the user is experiencing a fever, which can be used in screening for medical diagnostic testing.

A method for detecting a plurality of persons with fever including acquiring a first image by a camera, the first image including a first image data of at least a first person, acquiring a second image by a thermal imaging camera, wherein the second image includes a second image data of the first person and a temperature reference apparatus in an infrared spectrum, the second image, at least in sections, has an identical image area as the first image, superimposing the first image and the second image to form a third image, wherein the third image includes a third image data of the first image and the second image, determining a first measurement point within the first image data of the first image, and determining a first temperature for the first measurement point based on the third image and the second image data of the temperature reference apparatus.

A method for a hearing test includes receiving a first testing hearing threshold for a subject at a first frequency under a first background noise level; calculating a first testing signal-to-noise ratio (SNR) between the first testing hearing threshold and the first background noise level; responsive to the first testing SNR, receiving a first adjusted hearing threshold; and responsive to the first adjusted hearing threshold, modifying a first hearing test result of the first frequency.

A method, user device, and system for displaying augmented anatomical features is disclosed. The method includes detecting a target individual, displaying a visual representation of the body, and determining an anatomical profile of the target individual based on a plurality of reference markers. The method further includes displaying, on the display, a graphical representation of the inner anatomical features onto the visual representation of the body so as to assist in the identification of the inner anatomical features. In another aspect, an initial three-dimensional representation of the body is mapped and a preferred anatomical profile is determined based upon the reference markers. The initial three-dimensional representation of the body is modified to be the shape of the preferred anatomical profile and displayed.

A biological characteristic information detection device and an electronic device are provided. The detection device includes: a pressure detection module including a cantilever beam and a pressure sensor, where the pressure sensor is fixed on a surface of the cantilever beam, the cantilever beam includes an elastic arm and a fixed base, the fixed base is fixed in the electronic device, and the elastic arm is suspended in the air; and a PPG detection module arranged on the elastic arm and configured to detect a PPG signal of a user when the user presses the electronic device, where when the user presses the electronic device, a pressure signal applied to the electronic device is transmitted to the cantilever beam through the PPG detection module, so that the pressure sensor detects the pressure signal, and the pressure signal and the PPG signal are used to detect biological characteristic information.
