An Internet of Thing (IoT) device includes a camera coupled to a processor; and a wireless transceiver coupled to the processor. Blockchain smart contracts can be used with the device to facilitate secure operation.

Methods and systems are provided for measuring anatomical dimensions from a single two-dimensional (2D) digital image. The digital image is taken from the front/anterior view using a mobile, handheld communication device. The linear measurements are used to estimate the body volume of the individual. Total body density is calculated from estimated body volume and body weight. Body composition (fat mass and fat-free mass) of the individual is derived from density using known mathematical conversion formulas. A method for estimating body composition analysis is provided. Systems and methods are provided that determine an individual's fitness by determining body composition of the individual using a picture of the individual, determining the individual's VO.sub.2 max based on the individual's movement (e.g., walking and/or running a measured distance over a measured amount of time), and determining the individual's fitness based on the body composition and the determined VO.sub.2 max.

A biometric monitoring device and multiple carrying cases for same are provided. In some implementations, the case may be made from a flexible viscoelastic material and the biometric monitoring device may be slipped into a receptacle in the case through an opening in the case; the opening may become distended during the insertion of the biometric monitoring device. In some implementations, the case may feature a display window that, in combination with materials of the biometric monitoring device, may mask a display of the biometric monitoring device from view when the display is off and may allow the display to be seen when the display is displaying content.

An Internet of Thing (IoT) sport device includes a sensor coupled to a processor; and a wireless transceiver coupled to the processor.

We have disclosed systems and methods for portable performance monitoring of an individual during a physical activity. The systems and methods may include a portable sensor component configured to be carried by the individual during the physical activity and configured to obtain movement data for the athlete individual during the physical activity. The systems and methods may also include a portable output component configured to be carried by the individual during the physical activity and configured to provide an output to the individual during the physical activity. The systems and methods may further include a portable processing component in communication with the portable sensor component and the portable output component, where the portable processing component is configured to be carried by the individual during the physical activity. The portable processing component may be configured to identify movement of the individual during the physical activity.
