A method for assessing and reversing exercise impairment in adults having peripheral vascular disease includes quantifying a musculoskeletal deoxygenation level (MDL) of a human subject provided by a wearable near infrared spectroscopy system configured to measure the deoxygenation level during exercise, comparing the quantified MDL to a range of pre-determined healthy MDL values for the subject, and, if the quantified MDL is outside of the pre-determined target MDL values, determining a corrective exercise intensity level or ‘dose’ effective to bring the MDL of the subject within the target MDL values and reverse the exercise impairment.

Disclosed is a breath sampling device comprising a buffer tube, sensor module and breath sampling port. The buffer tube has a proximal end into which a user exhales and a distal end opposite the proximal end, the sensor module is at the distal end and used for measuring parameters of a breath exhaled by the user into the buffer tube, and the breath sampling port is disposed between the proximal end and distal end. The used exhales into the distal end and a portion of the exhaled breath can be diverted into the sampling port substantially without contacting the sensor module.

A uroflowmetry device including a funnel for funneling urine of a user, a sensor for measuring urine level in the funnel over a measurement period, a paddle wheel operable to rotate in response to urine exiting the funnel and generate a signal after each rotation during said measurement period, a transmitter for transmitting data from the uroflowmetry device to a smart device, and a processor. The processor configured to, while the user is urinating, compute a urine flowrate based on urine level in the funnel and a number of rotations of the paddle wheel over the measurement period, and transmit the urine flowrate to the smart device to provide real-time urination feedback to the user.

The present disclosure contains embodiments of an apparatus, system and method designed to facilitate learning or efficient multitasking involving movement and solar energy where users' movement devices process or respond to different stimuli to facilitate users moving while learning, working, or participating in a simulation. In some embodiments this may be accomplished with the aid of a circular treadmill, spherical walkway, or combinable modular trackpads that may be linked to allow a user to lay the apparatus in a path suited for a plurality of environments. The embodiments of the disclosure involve the user moving while processing information and receiving feedback, assistance related to that movement, processing, or any combination thereof while combining the motion of the movement device with the feedback loop sent from sensor relays a user may receive an optimal experience for learning while moving. Some embodiments make efficient use of solar energy for classroom education management.

Systems and methods are disclosed that facilitate visualizing how a user will appear in response to adhering to a health and fitness program. In an aspect, a system includes a reception component configured to receive information corresponding to a user's physical appearance and physical health, an analysis component configured to determine or infer one or more changes to the user's physical appearance based on predicted performance of a health and fitness program by the user and the user's physical health, and a visualization component is configured to generate a visual representation of the user based on the information and the one or more changes to the user's physical appearance.

Infusion devices and related medical devices, patient data management systems, and methods are provided for monitoring a physiological condition of a patient. An exemplary infusion device includes an actuation arrangement operable to deliver fluid to a user, a communications interface to receive measurement data indicative of a physiological condition of the user, a sensing arrangement to obtain contextual measurement data, and a control system coupled to the actuation arrangement, the communications interface and the sensing arrangement to determine a command for autonomously operating the actuation arrangement in a manner that is influenced by the measurement data and the contextual measurement data and autonomously operate the actuation arrangement in accordance with the command to deliver the fluid to the user.

A method and a system for providing feedback to a user for adjusting sleep pattern of the user. The method includes collecting a set of information related to the user, receiving a set of measurement data related to the user from a wearable electronic device, defining circadian rhythm and duration of sleep of the user, determining sleep scores for a predefined number of days and associating each sleep score with a corresponding go-to-bed time or time of falling asleep of the user. A sleep score is determined for each of the predefined number of days from the collected set of information, the set of measurement data, the circadian rhythm and the duration of sleep of the user. The method further includes analysing the sleep scores and associated go-to-bed time or time of falling asleep of the user to determine an optimum bedtime window for the user and providing feedback to the user based on the analysed sleep scores and the optimum bedtime window.

Described herein is a system including a catheter, an optical circuit, a pulsed field ablation energy source, and a processing device. The catheter includes a proximal section, a distal section, and a shaft coupled between the proximal section and the distal section. The optical circuit is configured to transport light at least partially from the proximal section to the distal section and back. The pulsed field ablation energy source is coupled to the catheter and configured to transmit pulsed electrical signals to a tissue sample. The processing device is configured to analyze one or more optical signals received from the optical circuit to determine changes in polarization or phase retardation of light reflected or scattered by the tissue sample, and determine changes in a birefringence of the tissue sample based on the changes in polarization or phase retardation.

In order to objectively grasp a stress state of a user and to prevent postpartum depression, biological gas information is acquired via a network, where the biological gas information indicates a concentration of tetradecane of the user and is obtained by a sensor that detects tetradecane released from a skin surface of the user. From a memory storing information including an upper limit of a normal range of the concentration of tetradecane per unit period, the information indicating the upper limit of the normal range is read out. When a frequency in the unit period with which the concentration of tetradecane of the user exceeds the upper limit of the normal range is determined to have an increasing tendency based on the biological gas information obtained during a pregnancy period of the user, the information related to stress of the user is output to an information terminal of the user.
