A housing for a Time-of-Flight (ToF) range meter includes a wall structure defining a first optical beam path to an emitter of the ToF range meter, and a second optical beam path to a detector of the ToF range meter, and a transmissive optical diffusor configured to cover the beam path to at least one of said emitter and said detector. The housing may be connected to a ToF range meter into a ToF ranging device. Such a ToF ranging device where the ToF ranging device is directed to measure a distance to a reflector member to determine a distance which correlates to the weight of the selectively engaged weights.

Embodiments of the disclosure provide a method, a device, and a computer-readable storage medium for arranging exercise intensity. The method includes: obtaining a user’s personal information and an exercise session, where the exercise session corresponds to an exercise fatigue; and providing a recommended exercise intensity for the exercise session based on at least the personal information and the exercise fatigue.

A computer-implemented system may include an electromechanical machine configured to be manipulated by a user while the user performs a treatment plan, an interface comprising a display configured to present information associated with the treatment plan, and a processing device configured to receive, from one or more data sources, information associated with the user, wherein the information comprises one or more risk factors associated with a cardiac condition or a cardiac outcome, generate, using one or more trained machine learning models, the treatment plan for the user, wherein the treatment plan is generated based on the information associated with the user, and the treatment plan comprises one or more exercises associated with managing the one or more risk factors in order to reduce a probability of a cardiac intervention for the user, and transmit the treatment plan to cause the electromechanical machine to implement the one or more exercises.

The disclosure relates to improvements in fitness device displays. In some aspects, the techniques described herein relate to a method including: initiating, by a fitness device, a short-range wireless connection with a display device; adjusting, by the fitness device, at least one operating parameter; broadcasting, by the fitness device, an identifier of the fitness device to the display device while the at least one operating parameter is being adjusted; and establishing, by the fitness device, a connection with the display device after a user of the fitness device selects the identifier when displayed on the display device.

Aspects relate to a portable device that may be used to identify a critical intensity and an anaerobic work capacity of an individual. The device may utilize muscle oxygen sensor data, speed data, or power data. The device may utilize data from multiple exercise sessions, or may utilize data from a single exercise session. The device may additionally estimate a critical intensity from a previous race time input from a user.

Systems and methods for prescribing athletic activity to be performed by a user, and for adapting the prescribed athletic activity based on completed (e.g. ongoing) athletic performances by the user. A coaching plan may be automatically created that prescribes personalized athletic activities as a user trains towards a goal date. The athletic information may be received from one or more sensor devices associated with a user, and the coaching plan may be continuously or intermittently updated based on the received sensor data.

A gait evaluation apparatus that evaluates a training gait of a paralyzed patient suffering from paralysis in a leg includes an acquisition unit configured to acquire a plurality of motion amounts of a paralyzed body portion according to a gait motion and an evaluation unit configured to evaluate that the gait motion is an abnormal gait in a case where at least one of the motion amounts acquired by the acquisition unit meets any one of a plurality of abnormal gait criteria set in advance. The abnormal gait criteria include at least two or more first criteria, which are criteria relevant to motion amounts of different parts of the paralyzed body portion, or at least two or more second criteria, which are criteria relevant to motion amounts of the same part of the paralyzed body portion in different directions.

A speed control system and method for controlling the speed of an endless belt loop of a treadmill. The speed control system comprises a plurality of image sensors, each image sensor configured to take an image of a user of the treadmill; and a controller configured to control the speed of the endless belt loop by (a) receiving the images of the user taken by the image sensors, (b) rectifying the images based on a calibration of the image sensors, (c) comparing the images to form a disparity map, (d) determining a distance of a user of the treadmill relative to the treadmill using the disparity map, and (e) calculating velocity or acceleration of the treadmill based on the determined distance of the user.

A climbing exercise machine includes a beam supported on two columns supported on a base. Two handles are movably supported on the columns, respectively. The handles are movable in opposite directions. Two treads are movably supported on the columns, respectively. The treads are movable in opposite directions. An input axle is supported on the columns. The input axle is rotated as the handles and the treads are moved. A transmission case connects the input axle to an output axle. A disc is connected to the output axle. A frame is connected to the beam. A resistance element is supported on the frame. The resistance element includes a magnet. The resistance element is movable relative to the disc to adjust magnetism exerted on the disc by the magnets.

Systems and methods for sensing and monitoring various athletic performance metrics, e.g., during the course of a game, a practice, a training session, training drills, and the like, are described. These systems and methods can provide useful metrics for players and coaches relating to athletic performances in various sports, including various team sports.
