Described herein are methods for determining a target musculoskeletal activity cycle (MSKC) to cardiac cycle (CC) timing relationship. The method may include detecting a first characteristic of a signal responsive to a CC timing of a user that repeats at a frequency that corresponds to a heart rate of the user; detecting a second characteristic of a signal responsive to a rhythmic musculoskeletal cycle activity (MSKC) timing of the user that repeats at a frequency that corresponds to the MSKC rate of the user; determining a value representative of an actual timing relationship between the first characteristic and the second characteristic; detecting a third characteristic of a signal corresponding to a physiological metric that varies with the actual timing relationship between the first and second characteristics; and determining a target value representative of a preferred timing relationship between the first and second characteristics.

An exercise bike and an operation method thereof are provided. In a test mode, a processing unit adjusts a resistance of a pedaling activity to be a plurality of pedaling resistances and obtains a plurality of psychological values respectively corresponding to the pedaling resistances by inquiring the user about a rate of perceived exertion. The processing unit calculates the psychological values to obtain a plurality of exercise intensities respectively corresponding to the pedaling resistances and further obtain a correspondence relationship between the exercise intensities and the pedaling resistances. After the test mode ends, the processing unit determines a recommended pedaling resistance according to the correspondence relationship. In a sport mode, the recommended pedaling resistance is provided to the user for performing the pedaling activity. The exercise bike determines the recommended pedaling resistance according to the user's physiological characteristics and/or a rate of perceived exertion regarding a physical activity.

A garment including a breath sensor module. The breath sensor module includes a stretchable sensor configured to respond to at least one of expansion and contraction of a torso of an individual wearing the garment. The breath sensor module also may include an electronics module. The electronics module includes, for example, a processor and a haptic feedback device. In response to the processor determining that the individual's breathing meets predetermined criteria based on the response of the stretchable sensor, the haptic feedback device produces haptic feedback such that the individual is reminded to breathe. Further, the breath sensor module does not include a transmitter or a receiver configured to transmit or receive data outside of the breath sensor module. Advantageously, this allows for streamlined use, and less-intrusive reminders to the individual wearing the garment, without the complexities of signal transmission or receiving.

A system for controlling a therapeutic device and/or environmental parameters can include one or more body worn sensor devices that detect and report one or more physical, physiological, or biological parameters of a person in an environment. The sensor devices can communicate sensor data indicative of the one or more physical, physiological, or biological parameters of a person to an external hub that processes the data and communicates with the therapeutic device to provide a therapy (e.g., neuromodulation, neurostimulation, or drug delivery) as a function of the sensor data. In some embodiments, the therapeutic device can be implanted in the person. In some embodiments, the therapeutic device can be in contact with the skin of the person. The sensor devices can also communicate to the hub that communicates with one or more devices to change the environment as a function of the sensor data.

Disclosed herein is a ventilator system and method, for alveolar micro-circulation enhancement using pulse cycle harmonized ventilation pressure modulation of a patient. The system includes a sensor unit, a controller unit and a supply unit. The sensor unit is configured to sense a set of physiological parameters to determine one or more cardiovascular activities of the patient. The controller unit is communicatively coupled to the sensor unit, and is configured to determine a dynamic pattern of an oxygenated air supply for the patient based on the sensed cardiovascular activity. The supply unit is communicatively coupled to the controller unit and is configured to supply the determined pressure wave to create a dynamic alteration in the air flow pattern of the ventilated air to the patient in response to the cardiovascular activity. Some embodiments of the system also represent the system as an air flow controlling apparatus, capable be coupled to any ventilator system internally or externally to control the flow of air in the dynamic pattern.

Embodiments of the disclosure provide a method, a device, and a computer-readable storage medium for arranging exercise intensity. The method includes: obtaining a user's personal information and an exercise session, where the exercise session corresponds to an exercise fatigue; and providing a recommended exercise intensity for the exercise session based on at least the personal information and the exercise fatigue.

Aspects of the present disclosure provide methods, apparatuses, and systems for non-linear breathing entrainment. According to an aspect, a final breathing period is selected, and a current breathing period of a user is measured. A guiding stimulus configured to alter the current breathing period towards the final breathing period over an interval of time at a non-linear prescribed rate is output. A difference between the current breathing period and a target breathing period along the non-linear linear prescribed rate is determined. Based at least in part on the difference, the guiding stimulus and/or the non-linear prescribed rate are adjusted. The guiding stimulus and the non-linear prescribed rate may be stabilized, increased, or decreased to enable the user to reach the final breathing period.
