Exercise machine including weight measurement system

DETAILED DESCRIPTION Based on at least the foregoing, aspects of the present invention include an exercise machine having a straightforward, accurate, discreet weight measurement system.
According to an embodiment, the weight measurement system communicates with a microprocessor to convey a signal representative of a value of a user's weight.
The microprocessor then employs the value to, for example, recommend exercise parameters, provide user feedback, configure the exercise machine, or the like.
According to an embodiment, the weight measurement system acquires the value during static operation of the exercise machine, such as before and after exercises are performed.
The weight measurement system preferably includes one or more load cells configured to output a signal indicative of a user's weight.
The weight measurement system also includes a calibration process providing for substantially error free load cell replacement as well as accurate determination of the user's weight.
In an embodiment employing two load cells, the weight measurement system outputs a signal representative of the user's weight regardless of whether the weight is equally distributed between the two load cells.
For example, the two load cells may each be arranged in a Wheatstone Bridge configuration, which when wired in parallel, outputs a signal representative of the user's weight even during unequal distribution.
According to a footpad detection embodiment of the weight measurement system, the exercise machine includes non-slip platforms or footpads designed to receive the user's weight in a comfortable and safe manner.
According to a deck detection embodiment of the weight measurement system, the exercise machine includes load cells attached to an exercise assembly in a manner supporting at least a portion of the weight of the assembly as well as the weight of the user.
