An apparatus for controlling of a training device including a training device configured to absorb a mechanical power applied by a person undertaking physical training, an assistance unit configured to assist the training and/or to make the training more difficult, and an exertion measuring apparatus configured to measure mechanical exertion data of an effort applied by the person during the training, a body sensor configured to measure physiological data of the body of the person, a computing unit configured, with an optimization algorithm, to adjust coefficients, a summand, and delays to prepare a prediction of the physiological data based on a model, and a control unit configured to take a predetermined reference variable for the physiological data, to take the prediction as a control variable, and to control an assistance of the assistance unit as a manipulated variable.

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 a specification, an error stop mode is entered for the tension generating device.

Systems and methods are for production, management, syndication and distribution of digital assets through a network such as the Internet or wireless network. Digital media assets are distributed to consumers through a syndicated network of Outlets under control of a central platform. Distribution is format agnostic. There is a single platform between the B2B2C, wherein a platform allows, through a single access for each stakeholder, the ability to each have control over availability dates and pricing specifications to a plurality of merchants and/or subscription outlets or channels. Subscription channels can support micro-subscriptions with diversely curated and priced offerings, including acceptance of crypto-currency. The delivered media assets may include content associated with an exercise apparatus, including content for an exercise session including computer generated content and computer augmented content created in response to exercise session data.

The invention relates to a golf bogey (5), characterized in that it comprises at least one humidity sensor. The invention also relates to a device for managing a golf course comprising at least one bogey according to the invention.

A smart ball-machine uses artificial intelligence to train a player or to play with a player. For example, the ball-machine can adjust the tennis ball speed, topspin, bounce according to the player's successful ball return rate. The ball-machine can be preconfigured with a profile of a player. For example, the ball-machine may download a complete profile of a tennis player from a game recording, or may download a file with a customized profile of a player to train a player using the ball-machine. The ball-machine is equipped with a plurality of wheels, motors, and shafts to provide a fully customizable launch of one or more balls. For example, the ball can be launched from the machine from one side of a tennis court to another side of a tennis court with a variety of speeds, trajectories, topspin, bounce etc.
