A portable apparatus includes an exercise-measurement circuitry that measures exercise-related measurement data related to a user carrying out an exercise, a communication circuitry configured to provide the portable apparatus with wireless communication capability, and a processing circuitry configured to a perform operations. The operations include receiving the exercise-related measurement data from the exercise-measurement circuitry, receiving configuration data from an external user interface apparatus over a bidirectional wireless communication connection established through the communication circuitry and capable of transferring payload data to both directions, processing the exercise-related measurement data according to the received exercise-related parameters in order to obtain advanced exercise-related data, and communicating the advanced exercise-related measurement data to the user interface apparatus over the bidirectional wireless communication connection.

A pulley force detection device for a weight-training fitness equipment includes a measured element arranged on a stator portion of a pulley of the fitness equipment, and a detection module arranged on a rotor portion. The detection module includes at least one measuring element corresponding to the measured element to detect a motion stroke, a speed, and a power value during force application to a pulley body. Alternatively, the measured element is arrangeable on the rotor portion of the pulley, while the measuring element is arranged on the stator portion of the pulley. The pulley force detection device is further combinable with a weight measurement device for detecting a weight of the weight block.

These systems and methods can provide useful metrics for players and coaches relating to athletic performances in various sports, including various team sports.

A portable smart hand grip according to an embodiment of the present disclosure includes a first housing, a guide part combined with the first housing and including a first receiving portion and a second receiving portion, a second housing facing the first housing and having a first pressing portion and a second pressing portion which are received in the first receiving portion and the second receiving portion, respectively, a first elastic member disposed between the first pressing portion and the first housing, a second elastic member disposed between the second pressing portion and the first housing, a sensor received in the first housing for detecting a user's operation of the portable smart hand grip, a control circuit unit received in the first housing to control an operation of the sensor, and a battery unit received in the first housing to provide power to the control circuit unit.

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.

A hand training device and corresponding method are used for sensing and measuring a capacitance corresponding to the pressure or force applied by the hand or fingers of the user. This hand training apparatus has slots for the index finger, the middle finger, the ring finger, and the pinky finger. The data obtained from the device can be utilized to create a 3-D model to indicate grip strength exerted by the hand or pinch strength.

An exercise machine comprises a motor. The exercise machine comprises a lockable translatable mount. The exercise machine comprises a cable coupled to the motor via the lockable translatable mount. The exercise machine comprises a sensor coupled to the lockable translatable mount. The sensor is used at least in part to determine mount lock state.

Disclosed herein are robust disposable alternating tangential flow (ATF) housing and diaphragm pump units and associated methods of manufacturing, testing, wetting, and using the same.
