  • Patent number: 9468794
    Abstract: A stationary exercise cycle includes a simulation system for simulating real-world terrain based on environmental and other real-world conditions. Using topographical or other data, an actual location can be simulated. The exercise cycle may include a resistance mechanism that is adjusted based on changes in simulated slope, and by amounts simulating actual frictional and gravitational forces. The simulated speed of the rider, as well as speed and direction of a simulated wind, are used to determine a simulated air speed. Based on the simulated air speed, the simulation system determines the simulated air resistance hindering the rider, and changes reflective of the simulated air resistance are made by the resistance mechanism. The stationary exercise cycle takes into account actual or approximate physical information of the user in determining the real-world conditions that are simulated, including the height, weight, shape, and/or rising position of the rider.

  • Patent number: 8052581
    Abstract: A dual actuation mechanism for controlling resistance applied to a rotating member includes a lever, a first actuator and a second actuator. The first actuator and second actuator are both operably coupled to the lever, wherein the first actuator and the second actuator move the lever independent of the other. For example, the lever may have a first slot for receiving the first actuator and a second slot for receiving the second actuator, wherein the first slot and second slot are sized such that when one actuator moves the lever, the other actuator is undisturbed because the respective slot moves with respect to the non-moving actuator. The dual actuation mechanism may be incorporated in an exercise cycle in which one of the actuators controls a level of resistance applied to a flywheel, and the other of the actuators selectively applies a stopping force to the flywheel.

  • Patent number: 8025611
    Abstract: An exercise apparatus includes a frame for residing on a horizontal surface, a pair of arm-supporting members for supporting the user's arms and a pair of leg-supporting members for supporting the user's legs. A linkage assembly couples the arm-supporting members and leg-supporting members to the frame and moves the arm-supporting members and leg-supporting members in closed paths relative to the frame in response to user forces applied to the arm-supporting members and leg-supporting members. The linkage assembly includes actuators for adjusting dimensions of the closed paths in response to control signal inputs. Sensors mounted on the linkage assembly generate force-indicating signals representing one or more of the user force. A user interface receives and processes the force-indicating signals and supplies the control signal inputs to the actuators, wherein a dimension of at least one of the closed paths is a function of at least one of the forces applied to the leg and arm-supporting members.

  • Patent number: 7976434
    Abstract: A control system and method for exercise equipment and the like provides a way to simulate a physical activity in a manner that takes into account the physics of the physical activity being simulated to provide an accurate simulation. According to one aspect of the present invention, the control system and method takes into account the physics of the corresponding physical activity to generate a virtual or predicted value of a variable such as velocity, acceleration, force, or the like. The difference between the virtual or expected physical variable and a measured variable is used as a control input to control resistance forces of the exercise equipment in a way that causes the user to experience forces that are the same or similar to the forces that would be encountered if the user were actually performing the physical activity being simulated rather than using the exercise equipment.

  • Patent number: 7955228
    Abstract: A bicycle trainer provides variable resistance to pedaling and allows for a rider to simulate a real-world bicycle course. The trainer engages both the front tire and the back tire of the bicycle and adjusts each according to the rider's preferences during a training session. The front tire lifts up and down as the bicycle moves forward and backward on the trainer. The back tire is adjusted by incorporating magnets thereon in the form of magnetic elements on a sleeve or a clip that engages the back tire and/or the back tire rim. The magnets on the back tire may also be attached to the spokes. The trainer includes magnets as well, usually of opposite polarity, and adds resistance to pedaling when the magnetic fields of the magnets interact to resist back tire revolution.

  • Patent number: 7901334
    Abstract: The present invention relates to an exercise apparatus with an adjustable resistance assembly. The adjustable resistance assembly has a screw portion. An user can rotate an operating portion which is connected to one end of the screw portion to move the screw portion to drive a pushing portion toward a rotating member which is pivotally connected on the exercise apparatus. Simultaneously, the pushing portion drives an elastic member to cause deformation and make a friction surface of a resistance member which is connected on the elastic member gradually press the rotating member therefore increases friction resistance. When the user rotates the operating portion reversely, the screw portion is moved outward the rotating member and the elastic member recovered from the deformation thereby decreases the friction resistance relative to the rotating member.

  • Patent number: 7850577
    Abstract: A clutch mechanism may be positioned in engagement with a slave sprocket of a drive train and a hub of a flywheel to create a frictional engagement between the sprocket and the hub, and to establish a break-free force threshold. When the drive train is actuated in the forward direction, the slave sprocket and the hub may move together, and when the drive train is actuated in the rearward direction under the influence of a force greater than the break-free force threshold, the clutch mechanism may slip between the slave sprocket and the hub, allowing the slave sprocket and the flywheel to move independently of one another. The clutch mechanism may also include a spring tensioner whereby the break-free force may be adjusted.
