A system for a treadmill including a tread that rotates around a front axle and a rear axle and side rails on opposing sides of the tread, comprises 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 the user on the side rail. The brake is not 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.

A lighting system is described for a treadmill, the treadmill including a tread that rotates around a front axle and a rear axle, wherein the tread comprises slats each having a tread surface and an underside. The lighting system includes a light positioned on at least one slat, wherein the light is configured to emit light between the adjacent slats and a controller in communication with the light and configured to control the light.

A method for processing and analysing data collected from workspace fitness devices while it is operated by a user. The method includes correlating that data with performance surveys filed by the user to determine the optimal sensory input that can influence the activity performance of that person while using a Smart Sit-and-Stand Desk, an Under-the-desk Bike, or other workspace fitness devices.

A ball collecting apparatus is provided that employs a human-powered ball transport system that moves balls from a collecting surface to a location above the collection surface. The ball collecting apparatus employs no motors or other artificially powered devices to retrieve and transfer balls, which makes it light and easy to maneuver. The ball collecting apparatus is primarily contemplated for use of picking up tennis balls, but other balls of various sizes may be accommodated by the apparatus, as it is scalable.

A braking system for a treadmill having a tread that rotates around a front axle and a rear axle and a side rail on each side of the tread that does not move includes a brake configured to apply a braking force to one of the front axle and the rear axle, a controller in communication with the brake, and a weight sensor under each side rail configured to detect a load indicating that a user is standing on the side rails, each weight sensor in communication with the controller. The controller is configured to, when the tread is moving, engage the brake when a first signal is received from each weight sensor contemporaneously that a load is detected and disengage the brake when a second signal is received from each weight sensor contemporaneously that the load is removed.

A network of devices that include Workspace Fitness Devices, such as Smart Under-the-desk Bikes and Smart Desk Controllers embedded in Smart Sit-and-Stand Desks that connect or talk to one another, electronically identify individual users, track their activities, connect to a remote server database, and modify its records. Secondary devices such as smartphones, can connect to this network to remotely monitor and control the settings on the devices such as the desk's height or the required tension in the Smart Under-the-Desk Bike. The performance data captured by this network of devices can be shared to fitness tracking software or devices. By using our invention, we plan to motivate employees that sit behind the desk for numerous hours throughout the day to improve their health, productivity, and overall wellbeing.

A plurality of control sequences is stored. A user state is detected. A next control sequence associated with the user is selected from the plurality of control sequences based at least in part on the user state.

A lighting system for a treadmill is described. The treadmill includes a tread that rotates around a front axle and a rear axle. The tread defines a cavity and comprises slats each having a tread surface and an underside. Each slat is attached at longitudinal ends to a respective belt that rotates on bearings around the front axle and the rear axle. The slats are configured with a space between adjacent slats. The lighting system comprises lights located in the cavity. The lights are configured to emit light away from the cavity through the space between the adjacent slats along at least a portion of the treadmill. A controller is in communication with the lights and is configured to control the lights.
