A pedal exerciser includes a worm shaft meshed with a worm wheel. A crank drives rotation of the worm wheel through two pedals. A rotary disc assembly is journaled to and rotatable with the worm shaft. The rotary disc assembly has a conductive member that is non-magnetizable and that is rotatable around an axis of the worm shaft. A magnetic assembly is disposed near the conductive member and has a magnet facing the conductive member. The magnet produces a drag force to resist an exercising force when the conductive member is rotated to move past the magnet. An adjustment assembly moves the magnetic assembly toward or away from the rotary disc assembly to vary the magnitude of the drag force.

A drag gain structure for the gravity wheel of fitness equipment includes an eccentric driving member disposed on the first side of the gravity wheel, which includes inner and outer side plate sections, and an interconnecting piece. The interconnecting piece is rotationally coupled to at least one of the plate sections. One end of outer side plate section is fitted over and fixed to the shaft, and one end of inner side plate section is connected to an eccentric position of gravity wheel through the first bias joint pin. A bearing pedestal is disposed on the second side of the gravity wheel, including a bearing screwed on the shaft, a pedestal shell fitted over the bearing and a radial protruding plate on the periphery of pedestal shell. The protruding end of the radial protruding plate is connected to an eccentric position of gravity wheel through the second bias joint pin.

Improvements in an exercise cycle is disclosed. The cycle is adaptable to an office chair with a hook feature that allows for easy engaging and disengaging of an office chair floor leg, support or caster. The extending hook allows for users of different heights to make use of the chair hook without requiring a user to change hooks to accommodate different heights of a user and office chair casters. The pedals are connected through a common axis and connect to a loading mechanism. There can be a flywheel and a transmission that alters the turning rate of the flywheel and/or the loading mechanism. The size and shape of the resistance loading housing is configured to fit under a common office desk. The user's weight, is transferred to the plate through the office chair caster to improve the stability of the desk bike.

In embodiments of animation using keyframing and projected dynamics simulation, an animation object is displayed with handles associated with object regions for the animation object, each handle being selectable for setting animation constraints on an object region. An animation simulator receives a user input designating a particular handle with an animation constraint, and sets the animation constraint on the particular handle for the associated object region. The animation simulator also receives another user input, designating a timing of the object region associated with the particular handle of the animation object through multiple frames in an animation sequence. The animation simulator projects a simulation of the animation object utilizing a projected dynamics algorithm that applies physics to simulate the set of object regions of the animation object in the animation sequence, the simulation including simulating the object region associated with the particular handle based on the timing and the animation constraint.

An exercise device with a crank housing supporting a pedal crank having a pair of opposing pedals that are pivotally mounted to the pedal crank. A first strut extends from the crank housing and is jointed to a second strut by a coupling that selectively allows the struts to rotate relative to each other so that the device may be folded into a planar configuration or extended for use. A cross-member is positioned at the end of each strut to form legs for supporting the pedal crank in an upright position. A tensioner is associated with the crank housing for selectively increasing and decreasing the force needed to turn the pedal crank. A telescoping arm may be used to interconnect the exercise device to a table or seat so that it can be folded and stored under the table or seat, and unstowed and unfolded for easy use.

An exercise device with a crank housing supporting a pedal crank having a pair of opposing pedals that are pivotally mounted to the pedal crank. A pair of struts extends from the crank housing and one of the struts has a hinge that allows the leg to fold inward into a collapsed configuration or extend and lock into place for use of the pedal crank. A cross-member is positioned at the end of each strut to form legs for supporting the pedal crank in an upright position. A strap may be coupled to one of the pair of legs for additionally securing the exercise device to an airline seat. A tensioner is associated with the crank housing for selectively increasing and decreasing the force needed to turn the pedal crank.

In one embodiment, a computer-implemented system includes treatment apparatuses configured to be manipulated by patients while performing an exercise session, patient interfaces associated with the plurality of patients, and a server computing device configured to receive first characteristics pertaining to the patients, and initiate a virtual shared session on the patient interfaces associated with the patients. The virtual shared session includes at least a set of multimedia feeds, and each multimedia feed of the set of multimedia feeds is associated with one or more of the patients. During the virtual shared session, the server computing device may present a first layout including the set of multimedia feeds, the first characteristics, or some combination thereof.
