A method for determining the tap time of a user in response to an auditory stimulus. The method includes: playing back the auditory stimulus corresponding to a reference audio signal, recording the reference audio signal and one or more vibro-acoustic events, the vibro-acoustic events following one or more taps by the user on a touch screen of the device in reaction to the reference audio signal, detecting the reference audio signal in the recorded audio signal, the recorded audio signal is recorded by a microphone of the touch-screen device, during the step of detecting the reference audio signal in the recorded audio signal, placing the reference audio signal and the recorded audio signal on a common time scale, filtering the detection and normalizing it to keep only the frequencies corresponding to the vibro-acoustic events generated by the user's actions on the touch screen, and detecting the vibro-acoustic events in which instants associated with the vibro-acoustic events are identified in the signal obtained after filtering.

An integrated sensing system for characterizing blood flow in a subject includes a light source assembly including a light source configured to emit light of a particular wavelength. The integrated sensing system includes an integrated circuit electrically connected to the light source assembly. The integrated circuit includes a light detector assembly including multiple light detectors configured to detect light of the particular wavelength; and a correlator configured to determining a delay between optical signals detected by respective light detectors of the light detector assembly.

An arousal-level determining apparatus includes a generating unit, a calculating unit, an identifying unit, and a determining unit. The generating unit generates heartbeat-interval variation data, which indicates changes in heartbeat interval, on the basis of heartbeat signals indicating subject's heartbeats. The calculating unit applies a band-pass filter, which allows passage of a certain range of frequencies, to each frequency band in the heartbeat-interval variation data while changing the frequency band, and calculates spectral density with respect to each frequency band applied with the band-pass filter. The identifying unit identifies a feature point corresponding to a spectral density peak in the calculated spectral densities in the frequency bands. The determining unit determines subject's arousal level on the basis of the identified feature point.

A mobile, hand-held communication device with a digital touch screen display and a camera for acquiring an image of the human body is programmed to function as a digital anthropometer. The user digitizes anatomical landmarks on the displayed image to quickly obtain linear measurements which are used with a known morphological relationship to make an anatomical prediction for clothing measurement, body composition and postural displacement with accuracy and without external equipment.

A method for acquiring gait parameters of an individual is disclosed. The method includes capturing calibration images from foot marker placed on feet or shoes of an individual while an individual is standing still, the calibration images are obtained from a camera worn by the individual, capturing subsequent time-varying images from the foot markers while the individual is walking, and comparing the calibration images to the subsequent time-varying images by a processing unit that is coupled to the camera to determine changes between the initial relative image size of the foot markers and the time-varying images of the foot markers as a function of time to analyze gait of the individual.

A system is disclosed including a measuring device comprising sensors configured to collect data from a user based on the sensor being at least one of in contact with and proximate to a section of skin of the user, a stress feature analyzer configured to determine a cardiovascular activity feature of the user, a skin conductance feature of the user, movement of the user, and skin temperature of the user based on the data collected with the measuring device, and a stress classifier configured to classify and report stress experienced by the user based on at least one of one feature selected from the cardiovascular activity feature and the skin conductance feature, and two features including a combination of the cardiovascular activity feature and the skin conductance feature, wherein when the skin temperature of the user exceeds a defined threshold, the stress classifier ceases to classify the stress experienced by the user. A method and a non-transitory processor readable storage medium are also disclosed.

Methods and devices to diagnose and treat fecal incontinence in females and males are provided. A multiple sensor-enabled catheter for positioning in a patient's rectum allows for the visualization and manipulation or positioning of an anatomical reference point(s) in the patient's body. A multiple sensor-enabled catheter for rectal insertion in a patient allows for the visualization and implementation of efficient and effective exercises to strengthen pelvic floor muscles.

An oral cleaning system provides motivating feedback to a user before brushing and includes: a power toothbrush (10); one or more sensors (26) on or within the toothbrush; a processor (30) within the toothbrush configured to process sensor information obtained from the one or more sensors during a first brushing session of a user; and a feedback system (40) on or within the toothbrush responsive to the processor and configured to communicate brushing information to the user at a time subsequent to the first brushing session but before a second brushing session of the user.

A measurement apparatus for measuring biological information includes a sensor that executes selectively at least a first detection mode or a second detection mode, and a controller. The controller controls switching to the second detection mode based on output of the sensor while the sensor is in the first detection mode.
