  • Patent number: 7837597
    Abstract: An exercise machine including a weight measurement system which provides a signal representative of a user's weight. An embodiment of the weight measurement system includes at least one load cell outputting a signal used by a microprocessor to determine an accurate value of the users weight. An embodiment of the weight measurement system includes a plurality of load cells using a Wheatstone bridge configuration to output a signal representative of a user's weight regardless of whether the weight is evenly distributed across each load cell. A calibration process calibrates the load cells for each exercise machine.

  • Publication number: 20100113223
    Abstract: A stationary exercise machine includes a system for electronically controlling a pedal resistance so as to simulate the riding of a road-going bicycle. The exercise machine includes a control system that monitors pedal velocity and that controls the resistive load generated by an electronically-controlled resistance mechanism. In one example, an electromagnetic device may vary a resistive load placed on a flywheel, which, in turn, varies the pedal resistance experienced by a user. When the user increases the pedal velocity, the resistance mechanism increases the resistive load. When the user decreases the pedal velocity, the resistance mechanism decreases the resistive load. In another example, the resistance mechanism varies the resistive load based on a gear selection by the user. The control system may also take into account other factors, such as the grade of the simulated ride, simulated wind resistance, or other frictional forces when calculating the resistive load.

  • Patent number: 7618345
    Abstract: An exercise machine has a universal holder that is adapted to facilitate communication between the machine and a variety of portable electronic device configurations. The universal holder can be formed of a material that is generally transparent to infrared signals, but that is generally optically opaque.

  • Patent number: 7585251
    Abstract: An exercise machine that varies a resistive load based on sensed changes in intensity of exercise. In one example, an electronic control system of a stationary bicycle adjusts a flywheel resistive load based on changes in the user's pedal cadence. During the exercise routine, subsequent increases or decreases in the pedal cadence cause, respectively, increases or decreases in the flywheel resistive load. In addition, the control system may execute the exercise routine after actuation of a single input key. In another embodiment, the user may simply start to exercise. The electronic control system may calculate a default flywheel resistive load based on initialization parameters, such as demographic data and/or exercise preferences.

  • Patent number: 7544154
    Abstract: A guard assembly for exercise bikes has a master sprocket guard and a slave sprocket guard that are separate from each other and that are positioned between a master sprocket and a slave sprocket. A flexible transmitter such as a belt or chain extends through a portion of the master sprocket guard and the slave sprocket guard but does not make more than incidental contact with the guards.

  • Patent number: 7025710
    Abstract: An exercise trainer with a stride multiplier mounted on a base having crank arms rotationally supported on the base with foot links connected to the crank arms at one end and supported for movement distally from the crank arms. Foot pedals are respectively supported for longitudinal movement on the foot links with a flexible connection between the foot pedals and a ground connection on the base and the foot links to provide a generally elliptical movement of the foot pedals. Pivotal levers having at least one portion connected for movement with the foot links are connected to the foot links by a pivotal connection. The pivotal levers have an upper portion with handles and a lower portion with at least a portion that can be disengaged from movement with the foot links.
