A drive unit is connected to the other one of the rotating assemblies, is configured to receive a control signal, and is configured to drive rotation of the other one of the rotating assemblies according to the received control signal. Eddy currents generated by the first rotating member provide resistance to the transmission unit. A resistance training machine having the resistance device is also disclosed.

A method is disclosed for using an artificial intelligence engine to modify resistance of pedals of an exercise device. The method includes generating, by the artificial intelligence engine, a machine learning model trained to receive measurements as input, and outputting, based on the measurements, a control instruction that causes the exercise device to modify, independently from each other, the resistance of the pedals. While a user performs an exercise using the exercise device, the method includes receiving the measurements from sensors associated with the pedals. The method includes determining, based on the measurements, a quantifiable or qualitative modification to the resistance provided by a pedal of the pedals. The resistance provided by another pedal of the pedals is not modified. The method includes transmitting the control instruction to the exercise device to cause the resistance provided by the pedal to be modified.

Methods, systems and devices are provided for motion-activated display of messages on an activity monitoring device. In one embodiment, method for presenting a message on an activity monitoring device is provided, including the following method operations: downloading a plurality of messages to the device; detecting a stationary state of the device; detecting a movement of the device from the stationary state; in response to detecting the movement from the stationary state, selecting one of a plurality of messages, and displaying the selected message on the device.

An exercise machine adjustable resistance system and method for efficiently varying the workout resistance for an exercise machine. The exercise machine generally includes a carriage movably positioned with respect to the at least one rail, a plurality of springs selectively connectable to the carriage to provide a resistance level to the carriage, a plurality of electrically actuated mechanical devices adapted to latch a corresponding one of the plurality of springs to the carriage when in the latch state and unlatch a corresponding one of the plurality of springs to the carriage when in the unlatch state and a control unit in communication with the plurality of electrically actuated mechanical devices to selectively control the state of each of the plurality of electrically actuated mechanical devices to be within the latch state or the unlatch state.

Systems and methods for prompting a user to perform an exercise and monitoring the exercise are provided. Multiple independent sensors or sensor systems may be used to calculate energy expenditure. Various criteria may be used to manually or automatically select the independent sensor or sensor system or combination that will be used with the energy expenditure calculations.

A treadmill includes a platform where the platform includes a first side panel and a second side panel spaced apart at a distance from the first side panel, and a gap defined between the first side panel and the second side panel. The treadmill also includes a running deck contained within the platform and exposed within the gap, a first pulley connected to the running deck, a second pulley connected to the running deck opposite the first pulley, a tread belt surrounding the first pulley and the second pulley. A motor is in mechanical communication with at least one of the first pulley or the second pulley. A cover is located over the motor. A scale mechanism is incorporated into the cover over the motor.

Generally, a system and method for an automatic detection of referee's decisions during a ball-game match are provided. The method may include receiving a plurality of images of a ball-game field generated during the ball-game match; determining, based on predetermined ball-game rules, a first subset of images of the plurality of images representing a first event that is suspected as a specified rule-based event; determining, based on the predetermine ball-game rules, a second subset of images of the plurality of images that represents a second event, wherein the second event is subsequent to the specified rule-based event according to the predetermined ball-game rules; and analyzing, based on the predetermined ball-game rules, the images of the second subset and further determining, based on the analysis thereof, a referee's decision concerning whether the first even is the specified rule-based event.

A fitness tracking system includes a shoe, a monitoring device, and a controller. The monitoring device is mounted on the shoe and includes an accelerometer configured to generate acceleration data corresponding to acceleration of a foot received by the shoe. The controller is operably connected to the accelerometer and is configured to collect sampled acceleration data by sampling the generated acceleration data, to identify foot strike data of the sampled acceleration data, to identify a local minimum of the sampled acceleration data collected prior to the foot strike data, and to determine foot strike characteristic data corresponding to the foot strike data based on an acceleration value at the local minimum.

A method of determining biological movement includes detecting movement of a monitored portion of a person's body with a first sensor, detecting a potential of a muscle responsible for the movement with a second sensor, and determining whether or not the movement is normal, wherein the determining determines that the movement is normal, in response to a joint occurrence of the first sensor detecting the movement and the second sensor detecting the potential of the muscle responsible for the movement.
