  • Exercise machine including weight measurement system
    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.
    Type: Grant
    Filed: October 9, 2008
    Date of Patent: November 23, 2010
    Assignee: Unisen, Inc.

  • Control circuit using toggled activation to reduce inrush currents
    Patent number: 7481744
    Abstract: Aspects of the present invention include a controller circuit for an exercise machine, where the controller circuit includes a board mounted transformer having tolerances near or below the inrush current generally present in activating one or more cooling fans. According to one embodiment, the controller circuit attempts to power on a subsequent fan after the sum of the inrush or steady state current of presently operating fan or fans, and the inrush current generally associated with powering on the subsequent fan, is within the tolerances of the transformer.
