Patent number: 7837597Abstract: 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.Type: GrantFiled: October 9, 2008Date of Patent: November 23, 2010Assignee: Unisen, Inc.Inventors: Javier J. Reyes, Kevin P.

Publication number: 20100113223Abstract: 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.Type: ApplicationFiled: January 12, 2010Publication date: May 6, 2010Applicant: UNISEN, INC., DBA STAR TRACInventors: Mark W.

Patent number: 7585251Abstract: 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.Type: GrantFiled: November 30, 2004Date of Patent: September 8, 2009Assignee: Unisen Inc.Inventors: James M. Doody, Jr., Kevin P. Corbalis, Gregory Allen Wallace
