Disclosed herein are systems, devices, and methods for evaluating or analyzing complex audio signals using multi-dimensional statistical signatures and machine learning algorithms. One advantage of the present disclosure is the ability for remote evaluation of respiratory tract health using speech analysis. The need for remote collection capabilities that can sensitively and reliably characterize respiratory tract function is particularly pertinent in view of the recent Covid-19 pandemic, which may adversely affect the health of individuals who could already be experiencing health problems with respiratory tract function.

A method of measuring skin moisture includes: measuring, in response to a touch on a touch panel, a first capacitance for a touch area in association with driving first and second electrodes of the touch panel in a mutual sensing mode; measuring, in response to the touch, a second capacitance for the touch area in association with driving one electrode of the first and second electrodes in a self-sensing mode; comparing the first capacitance with a first reference capacitance; determining, in response to the first capacitance being greater than the first reference capacitance, a skin moisture level using the first capacitance and the second capacitance; comparing, in response to the first capacitance being less than the first reference capacitance, the second capacitance with a second reference capacitance; and compensating, in response to the second capacitance being greater than the second reference capacitance, the first capacitance using the second capacitance.

A system includes: a light source that emits pulsed light that illuminates a user's head portion; a photodetector that detects at least part of pulsed light returning from the head portion and that outputs one or more signals corresponding to an intensity of the at least part; electrical circuitry; and a memory that stores an emotion model indicating a relationship between the one or more signals and emotions. Based on a change in the one or more signals, the electrical circuitry selects an emotion by referring to the model. The one or more signals include a first signal corresponding to an intensity of first part of the reflection pulsed light and a second signal corresponding to an intensity of second part of the reflection pulsed light. The first part includes part before a falling period is started; and the second part includes at least part in the falling period.

A non-interdependent displacement measuring device for converting a rotary motion to a linear motion is disclosed, which includes a driving unit, a detection unit, and a resistance device. The driving unit includes an adjustment section and a driving section. The detection unit is arranged in the adjustment section. The driving section is connected to the resistance device. The detection unit includes a sensing module and a transmission module, and the detection unit is arranged in the adjustment section, so that when the adjustment section rotates, the detection unit detects turns and an angle of rotation of the adjustment section to generate a detection signal, which, after being subjected to calculation, is transmitted through the transmission module to the electronic device to display the level of an resistance, so as to overcome the drawbacks of the prior art that accuracy is poor, calibration is difficult, and fabrication is difficult due to a magnet and a sensor being arranged as two separate parts.

A system and method is provided for monitoring a biological substance in a bodily orifice. The system includes a wearable device configured to be worn in a bodily orifice. A biosensor is carried by the wearable device and is constructed and arranged to obtain raw data regarding a biological substance in the orifice. The biosensor includes a processor circuit to provide processed data from the raw data, and a transmitter to wirelessly transmit the processed data to a second device.

Systems and methods for detecting data acquisition conditions using color-based penalties can include a computing device obtaining a sequence of images acquired by a photodetector. The computing device can determine, for each pixel position of a plurality of pixel positions associated with the sequence of images, a respective penalty score indicative of a similarity between a color value of a pixel of the pixel position and a desired color value. The desired color value can represent a color property of light emitted from body parts of users when placed opposite to the photodetector. The computing device can determine, using penalty scores of the plurality of pixel positions, a relative position of a body part of a user with respect to a desired position.

An on-person portable device and/or app that allows for constant location monitoring of dementia patients is disclosed. Such a device and/or app also includes automated communication of facial recognition of persons proximally near such a patient as well as possible generation of certain music in response to patient status and/or location. The patient is provided the device and/or app for handling or wearing, such as a phone or pair of glasses, in order to follow location through GPS monitoring, and a reactive program therein that automatically views another person and provides an identification thereof coupled with a voice modulator within an earpiece or like device for memory stimulation pertaining to loved ones or friends, and the like. The same program may also provide the music response to comments, movement, or any other external stimuli to the subject patient, again, to evoke a memory stimulus, as well.

Disclosed is a care device recommendation server providing a service for recommending a skin care device for a user, the care device recommendation server including: a data management unit configured to obtain face images of the user from a shin measurement device including a camera and a display; a skin condition determination unit configured to determine a first skin condition of the user corresponding to a first time point at which the face images are obtained, based on the obtained the face images; a care device recommendation unit configured to determine the skin care device for the user among a plurality of care devices included in a care device DB based on the determined first skin condition; a care device control value-providing unit configured to provide a first control value of the skin care device corresponding to the first skin condition to each of a user terminal of the user and the skin measurement device; a care device control unit configured to remotely control the care device such that the skin care device is driven by the control value; and a history provision unit configured to provide information about a previous skin condition of the user, which corresponds to each of the face images of the user obtained from the data management unit, to the user terminal.

Systems and methods for blood pressure estimation using smart offset calibration can include a computing device associating a calibration photoplethysmographic (PPG) signal generated from a first sequence of image frames obtained from a photodetector of the computing device with one or more measurement values generated by a blood pressure measurement device different from the computing device.
