Sensor data is collected from a sensor monitoring a tension generating device of an exercise machine. The sensor data is analyzed to determine whether the sensor data is within a specification. In the event the sensor data is not within the specification, an error stop mode is entered for the tension generating device.

System for mechanically assisting rehabilitation of a patient. The system includes: a manipulator having at least five degrees of freedom and defining a free end; a limb support for supporting a limb of the patient, and secured relative to the free end of the manipulator; a force sensor operatively connected to the limb support to allow measuring input forces applied by the patient; and a processor communicatively connected to the force sensor, the manipulator, and a memory store which defines a scale factor. The processor is configured to control operation of the manipulator to move the limb support, and further configured so that responsive to receiving an input force measurement from the force sensor, the processor determines an applied force as a function of the input force and the scale factor.

The described embodiments relate to systems, methods, and apparatuses for providing linear tension to multiple areas of a person to improve training and exercise. The tension can be applied by cables supplied from cable spools that are attached within a resistance assembly. The resistance assembly can be worn as a backpack during exercises, thereby providing a portable means through which tension can be provided to the body. The cables from the resistance assembly can be attached to appendages such as the wrists and legs of the person, and the tension provided by the cables can be adjustable. For instance, the tension can be made non-uniform across the body in order to improve the person's ability to maneuver in situations where there is an imbalance of force on the body.

The described embodiments relate to systems, methods, and apparatuses for providing an adjustable amount of tension to various portions of a body of a user. The tension can be exhibited by cables that extend from the body mounted device. The cables can be routed through a pulley assembly located with cables guides of the body mounted device. A user can adjust the tension of the cables using knobs located at the ends of the cable guides. The cables can terminate at bands, which can be attached to appendages of the user during training. When the user is wearing the body mounted device, a mounting plate of the body mounted device can conform to the shoulders of the user, and a separate plate of the body mounted device can be depressed against a back side of the user.

A swing analysis method includes acquiring measurement data measured by an inertial sensor in a swing motion with a golf club, and calculating torque data indicating a temporal change of a torque exerted on the golf club by analyzing the measurement data using a head speed coordination system having a first axis including a speed vector of a head of the golf club, a second axis being orthogonal to the first axis and extending along a shaft of the golf club, and a third axis orthogonal to both the first axis and the second axis.

A wearable device and an exercise support method performed by the wearable device are disclosed. The exercise support method includes receiving exercise setting information associated with a lower body muscle that is selected by a user input, determining a torque profile to be applied to the wearable device based on the received exercise setting information, and operating an actuator of the wearable device based on the determined torque profile.

The computing device is configured to receive parameters associated with the user during use of the dry swim simulation system from numerous electrical and/or mechanical components. The computing device is configured to analyze the parameters and provide real-time feedback to the user to improve performance of swimming strokes.

A method of varying a dynamic resistive force during a strength training exercise includes receiving a selection of the strength training exercise from a set of available strength training exercises and obtaining exercise logic for the strength training exercise from computer memory. The exercise logic provides instructions for generating a vector that defines the dynamic resistive force provided at an end effector of a strength training apparatus during the strength training exercise. The method includes determining a real-time geometric arrangement of a plurality of cables coupled to the end effector, generating, based on the real-time geometric arrangement of the plurality of cables and the exercise logic, time-varying operating setpoints for a plurality of actuator assemblies coupled to the plurality of cables, and exerting the dynamic resistive force at the end effector by controlling the plurality of actuator assemblies in accordance with the time-varying operating setpoints.

A treadmill includes a frame; a running belt configured to rotate relative to the frame; and a motor coupled to the running belt. The motor is operable in a plurality of user controlled operating modes. In a first operating mode, a user of the treadmill provides a force of rotation to the running belt. In a second operating mode, the motor is adapted to resist rotation of the running belt. In a third operating mode, the motor is adapted to provide a force of rotation to the running belt at a desired speed.

According to one example, an exercise system includes a vertical housing, a first weighted touchpoint coupled to the vertical housing and configured to allow a user to exercise one or more muscles on a first side of the user, a first weight system coupled to the first weighted touchpoint, a second weighted touchpoint coupled to the vertical housing and configured to allow the user to exercise one or more muscles on a second side of the user, and a second weight system coupled to the second weighted touchpoint. The exercise system further includes a control system configured to cause the first weight system to automatically provide a first heavier weight to the first weighted touchpoint for a first exercise and further cause the second weight system to automatically provide a second lighter weight to the second weighted touchpoint for the first exercise.
