A treadmill safety control system, method, and apparatus are described for operating an exercise treadmill by enabling a treadmill motor to start moving the treadmill belt after an initial height of the user on the treadmill belt is measured, and then continually measuring a current height of the user on the treadmill belt for evaluation against the initial height so that a first treadmill motor control signal is generated to stop the treadmill motor from moving the treadmill belt when the current height is lower than the initial height by a minimum height threshold.

A control method of an exercise device using cable is proposed. The control method of an exercise device according to the present disclosure may include a posture detection step at which whether posture is incorrect is detected. Additionally, the control method of an exercise device according to the present disclosure may include a load decrease step at which an exercise load is decreased when incorrect posture is detected at the posture detection step. Accordingly. it is possible to prevent the occurrence of accidents by detecting that a user's posture is incorrect.

An exercise machine includes computers, sensors, and at least one robotic arm, each robotic arm has a connector through which the robotic arm exerts force and torque on a user. Each robotic arm moves along a reference trajectory. The computer controls the robotic arm according to the corresponding reference trajectory. The sensors include force-torque sensors configured to measure the force and torque exerted on the user and vision sensors configured to measure the user's body posture. A method for controlling the exercise machine includes selecting an exercise motion, setting initial values for resistance force magnitude parameters and state variables, determining the user is ready to start exercising, obtaining measurements from the sensors, and based on the obtained measurements, updating the resistance force magnitude parameters and the state variables.

The present disclosure relates, in various embodiments, to improved simulation technology for use with a stationary training system. In some embodiments, this includes use of sensors, for example, wearable sensors, to control simulation parameters (such as display and/or performance parameters). For example, in some embodiments, a body worn sensor, such as an accelerometer and/or gyroscope, is used thereby to infer body position attributes of a user and, in response, configure one or more simulation parameters. These may include, for example, display parameters (for example, whether a simulated avatar is seated or standing) and/or performance parameters (for example, simulated wind resistance).
