This invention is embodied by a controlled, variable tension line, payout reel machine. A system of sensors detect line tension and line distance paid out, location, and transmit through wired and unwired communication to a microprocessor. The microprocessor is co-located with the reel structure, which in turn applies, via a brake feature, resistance to the reel which is paying out the line being pulled by the user. This invention pertains to all applications where it is desirable to control the tension in a line paid out from a reel or reel. As stated, the payout motive force is supplied by the person, animal or apparatus attached to the end of the line, opposite the reel. The invention applies to the field of precise and measured control of line tension for sport, sport training, performance testing.

In one aspect of the disclosure, a method that involves keeping state of a video workout program may include communicatively coupling a server in a cloud network to an exercise machine through a first network connection, communicatively coupling the server to a network device through a second network connection, the server providing a video workout program to the exercise machine for execution at the exercise machine to enable a user to perform at least a portion of a workout of the video workout program on the exercise machine, the server keeping state of the video workout program during execution of the video workout program based on inputs from the exercise machine and the network device, and taking an action based on the state. The action may include synchronizing multiple displays, adaptively scaling the video workout program, and/or generating and providing an exercise machine control command to the exercise machine.

A system for a manual treadmill having a tread that rotates around a front axle and a rear axle and side rails on opposing sides of the tread includes a brake configured to slow rotation of at least one of the front axle or the rear axle, a controller, and a first presence sensor in communication with the controller, the first presence sensor positioned on a side rail and configured to detect a user on the side rail. The brake is not normally engaged during operation of the treadmill when the tread is moving and the first presence sensor does not detect the user on the side rail. The controller is configured to, in response to the first presence sensor subsequently detecting the user on the side rail, engage the brake.

Athletic performance monitoring systems and methods, many of which utilize, in some manner, global positioning satellite (“GPS”) data, provide data and information to athletes and/or to equipment used by athletes during an athletic event. Such systems and methods may provide route information to athletes and/or their trainers, e.g., for pre-event planning, goal setting, and calibration purposes. Such systems and methods optionally may provide real time information to the athlete while the event takes place, e.g., to assist in reaching the pre-set goals. Additionally, data and information collected by such systems and methods may assist in post-event analysis for athletes and their trainers, e.g., to evaluate past performances and to assist in improving future performances.

A rowing exercise device comprises a support structure; a movable user support movably associated with the support structure for movement relative to the support structure; a movable foot support movably associated with the support structure for movement relative to the support structure; a handle; and a rowing assembly operatively associated with the handle and at least the movable foot support to cause at least the movable foot support to move relative to the support structure with movement of the handle so that both a user s body and one or both feet move relative to the support structure with movement of the handle.

An Internet of Thing (IoT) sport device includes a body with a processor, a camera and a wireless transceiver coupled to the processor.

A treadmill includes a running belt defining a non-planar running surface, and a motor operatively coupled to the running belt. The treadmill is operable in plurality of operating modes to control a user experience.

An integrated multi-purpose hockey skatemill with a movable skatemill belt (2) comprising a stationary area of the artificial ice (1) with a front face of the work area wherein a movable skatemill belt (2) is built in by means of barrier-free transition areas with a system of spaced signalization/display elements (5) hung on the tiltable/sliding brackets (5a) at the frontal and lateral sectors with respect to the center of the movable skatemill belt (2). There is a safety restraint system (3) and a stabilization system (4) anchored above the movable skatemill belt (2). A tensile/compressive force measuring system (8) is suspended from above in the longitudinal axis of the movable skatemill belt (2). The said skatemill comprises an electronic control unit (9) ECU controlling the operation of the movable skatemill belt's (2) drive system, the system of signalization/display elements (5), the system of optical scanning cameras (6) and the tensile/compressive force measuring system (8). There are two puck feeders (7) located on the border line defining the front side of the work area. There is a hockey goal structure with target zones impact detection sensors located on the edge of the work force in front of the movable skatemill belt (2). Two laser markers (12) used to define the width of a skate track may be located on the stationary area of the artificial ice in front of the movable skatemill belt.

An exercise and communications system includes an interactive device, a remote device, and an external device, wherein the interactive device is configured to gather data relating to a user of the system and transmit the same to the remote device, and the remote device is configured to provide analyze the data and transmit a response to the interactive device, which in turn communicates the response to the user and additionally communication with an external device for retrieval of instructions, programs, and data, inter alia. An exercise and communications system facilitates communication between a plurality of users, each having an interactive device and a remote device.

An exercise apparatus includes a frame and a load mechanism disposed on the frame. The load mechanism has a plurality of selectable weights with each of the selectable weights having an associated indicator device. A press is mechanically coupled to the load mechanism to displace a load based on a selected weight and a sensor is disposed to measure an extent and speed of displacement of the load. A processor is in communication with the sensor, and the processor is configured to determine an indicator signal to send to the indicator device of one of the plurality of selectable weights of the load mechanism based on received performance data, the indicator signal used to indicate which one of the plural of weights to select.
