A method includes: supporting a normal operation mode, during which functionalities of a portable apparatus are available through an operating system of the apparatus, wherein the operating system includes a plurality of layers including a kernel and library functions layer; supporting a limited operation mode during which the apparatus is configured to execute a physical activity algorithm based on physical activity data corresponding to a physical activity session performed by a user of the apparatus, wherein the physical activity algorithm applies a direct low-level hardware access bypassing at least the layers above the kernel and the library functions-layer; and switching between the normal operation mode and the limited operation mode.

A positive exhalation pressure device increases the pressure gradient in the airways, thereby increasing oxygen saturation levels and decreasing the severity of hypoxia. Various embodiments of the device may be inserted into the nasal and/or oral cavities, or configured as mask devices covering the nasal and/or oral cavities. In some embodiments, the resistance of the device may be varied.

The present disclosure is directed to systems and methods of determining a quality or type of a physical activity such as a fitness center. Generally, in one aspect, a controller for determining a quality or type of a physical activity performed by one or more persons in a spatial area is provided. The controller is configured to: (i) determine an activity pattern based on infrared energy detected in a spatial area by one or more thermopile sensors; (ii) determine a difference between said activity pattern 110 and a nominal pattern; (iii) determine a quality or type of a physical activity performed by said one or more persons based on said difference; and (iv) provide an output signal based on said quality or type of said physical activity in said spatial area. The quality of said physical activity may be a safety determination. The type of said physical activity may be a physical activity determination.

A social engagement system includes a first exercise machine having a display able to present videos, a three-dimensional camera system, and local processing system able to provide pose estimation based on data from the three-dimensional camera system. The system also includes a communication module for connection to a cloud processing system, with the cloud processing system supporting connection to a second exercise machine having a display able to present videos, a three-dimensional camera system, and local processing system able to provide pose estimation based on data from the three-dimensional camera system. Additionally, the connection allows transfer of data useful for social engagement.

Apparatus, systems, and methods for tracking the location of an individual during a fitness activity are disclosed. A method of tracking a participant engaged in a fitness activity includes determining a location of the participant during the fitness activity based on data received at a portable fitness device used by the participant; determining a location of a spectator during the fitness activity based on data received at a mobile spectator device used by the spectator; from a server, sending an alert to a spectator at a spectator device during the fitness activity indicating that the participant is within a predetermined distance of the spectator; and sending an alert to the portable fitness device during the fitness activity indicating that the spectator is within a predetermined distance of the participant.

Described herein are systems and methods of guiding a user to achieve musculoskeletal counterpulsation. A method may include receiving a cardiovascular cycle signal from a first sensor; determining a heart rate of the user based on the cardiovascular cycle signal; receiving a rhythmic musculoskeletal activity timing signal from a second sensor; determining an actual musculoskeletal activity cycle (MSKC) to cardiovascular cycle (CC) timing relationship; comparing the actual MSKC to CC timing relationship to a target MSKC to CC timing relationship; providing a recurrent prompt to the user as a timing indication for performance of a rhythmic musculoskeletal activity to guide the user to achieve a musculoskeletal activity cycle rate (MSKR) that approaches the target MSKC to CC timing relationship; and altering a feature of the recurrent prompt based on a determined alignment between the actual MSKC to CC timing relationship and the target MSKC to CC timing relationship.

An example method for providing enhanced event visualizations based on location data includes receiving, by a visualization processor, location data and sensor data for a plurality of participants; determining an impact indication for two or more participants of the plurality of participants based at least in part on the location data and sensor data; determining, by the visualization processor, a location of impact based on the impact indication and the location data and sensor data for the two or more participants; and generating an impact visualization interface configured to visually indicate impact data associated with the impact indication proximate the impact location.

The present invention relates to a body resistance physical exercise device with monitoring and fitness tracking capabilities, comprising: a) an electrical monitoring element configured to measure information relative to exercise parameters during repetitive motions performed with said device; and b) an elastomeric band adapted to enable the repetitive motions, wherein the resistance of the elastomeric band is capable of being adjusted.

A self-contained, hyperthermic conditioning unit and selectively controllable environment for exercising. The unit comprises a base portion having a bed therein and a removable cover connected to the base portion to enclose a personal compartment within the unit. One or more heating elements provide heat to the personal compartment and one more pieces of physical exercise equipment are provided within the personal compartment.

A smart mirror can show live or recorded streaming video of an instructor performing a workout in a package that is attractive and unobtrusive enough to hang in a living room. The smart mirror includes a mirror surface with a fully reflecting section and a partially reflecting section. A display behind the partially reflecting section shows the video when the smart mirror is on and is almost invisible when the smart mirror is off. The smart mirror also has a speaker, a microphone, and a camera to enable a user to view the video content and interact with the instructor. The smart mirror may connect to the user's smart phone, a peripheral device (e.g., a Bluetooth speaker) to augment user experience, a biometric sensor to provide biometric data to assess user performance, and/or a network router to connect the smart mirror to a content provider, an instructor, and/or other users.
