An electronic device may comprise audio processing circuitry, pace tracking circuitry, and positioning circuitry. The pace tracking circuitry may be operable to selects songs to be processed for playback, and/or control time stretching applied to such songs, by the audio processing circuitry based on position data generated by the positioning circuitry, a desired tempo, and whether the songs are stored locally or network-accessible. The position data may indicate the pace of a runner during a preceding, determined time interval. The pace tracking circuitry may control the song selection and/or time stretching based on a runner profile data stored in memory of the music device. The profile data may include runner's distance-per-stride data. The electronic device may include sensors operable to function as a pedometer. The pace tracking circuitry may update the distance-per-stride data based on the position data and based on data output by the one or more sensors.

A method for adjusting a working state of an electronic device includes setting a reasonable value range of feature data of a user, and acquiring current feature data of the user from the camera device. The current feature data is compared to the reasonable value range of feature data. A working state of the electronic device is changed when the current feature data is out of the reasonable value range of feature data.

The present invention discloses a running parameters detection system for treadmills and detection method thereof, wherein the system detects the running change data generated by a user running on a treadmill configured with a running belt, a motor and an electronic circuit device by means of a sensor, as well as the running belt operation speed data of the treadmill, in which the running change data is the current data or vertical acceleration data; subsequently, the running change data can be further applied to determine the touchdown moment recording point and the off-ground moment recording point, thereby then, based on such two time points, further calculating various kinematic parameters, e.g., touchdown time, in-the-air time, stride frequency, stride length and vertical amplitude or the like; for example, such five kinematic parameters can be utilized for scientifically monitoring and training runners.

Disclosed is a technical training garment configured for use with modular, interchangeable biomechanics units and or resistance modules. The garment may provide resistance to movement throughout an angular range of motion and or tracks a variety of biomechanical parameters such as stride length, stride rate, angular velocity and power expended by the wearer. The garment may be low profile, and worn by a wearer as a primary garment or beneath or over conventional clothing or athletic uniform. The device may be worn as a supplemental training and or diagnostic tool during conventional training protocols, or as a biomechanics or biometric data capture device during competition.

Disclosed herein are examples of user-paced exercise equipment, as well as related circuitry, methods, and computer-readable media. For example, disclosed herein is a user-paced treadmill, including a belt, a motor coupled to the belt, and control circuitry communicatively coupled to the motor. The control circuitry may be configured to change a velocity of the belt based at least in part on a body velocity and a leg swing velocity of a user of the user-paced treadmill.

An electronic device may comprise audio processing circuitry, pace tracking circuitry, and positioning circuitry. The pace tracking circuitry may be operable to selects a tempo of songs for playback, by the audio processing circuitry based on position data generated by the positioning circuitry, a desired tempo, and whether the songs are stored locally or network-accessible. The position data may indicate the pace of a runner during a preceding, determined time interval. The pace tracking circuitry may control the song selection and/or time stretching based on a runner profile data stored in memory of the music device. The profile data may include runner's distance-per-stride data. The electronic device may include sensors operable to function as a pedometer. The pace tracking circuitry may update the distance-per-stride data based on the position data and based on data output by the one or more sensors.

A method, apparatus, or system for reducing gait asymmetry is disclosed. The method, apparatus, or system may include measuring one or more gait parameters of an individual; calculating a joint metric based on the measured one or more gait parameters; and signaling an adjustment of an amount of one or more perturbation techniques based on the joint metric for reducing asymmetry in a gait pattern of the individual. The one or more perturbation techniques include asymmetric rhythmic auditory cueing making a first audible cue with a first cue duration for one leg of the individual and a second audible cue with a second cue duration for another leg of the individual. Here, the first cue duration is different from the second cue duration. Other aspects, embodiments, and features are also claimed and described.
