Abstract
Belt wear of a treadmill is determined. Samples of electric current draw of a treadmill at different speeds of the treadmill belt of the treadmill are received. A value of each sample is differently weighted based on a speed of the treadmill belt at which the value of each sample was obtained. A belt wear notification is output based on the different weighted values of the samples.
Claims21
A treadmill comprising:
- a belt upon which a runner exercises;
- a motor operably coupled to the belt to drive the belt;
- an electric current sensor to output signals indicating an electric current draw of the treadmill;
- and
- a controller to:
- receive samples of electric current draw of the treadmill at different speeds of a treadmill belt of the treadmill;
- differently weigh a value of each sample based on a speed of the treadmill belt at which the value of each sample was obtained;
- and
- output a belt wear notification based on the different weighted values of the samples.

A treadmill comprising:
- a belt upon which a runner exercises;
- an electric current sensor to output signals indicating an electric current draw of the treadmill;
- and
- a controller to:
- receive and store first samples of electric current draw from a first workout on the treadmill;
- receive and store second samples of electric current draw of the treadmill from a second workout on the treadmill;
- and
- output a belt wear notification based on the first stored samples and the second stored samples.
5 more elements
A treadmill comprising:
- a belt upon which a runner exercises;
- an electric current sensor to output signals indicating an electric current draw of the treadmill;
- and
- a controller to:
- maintain a workout array, the workout array comprising an array of a predefined number workouts, each of the workouts comprising a weighted average of amperage values received from the electric current sensor for each of a plurality of speed ranges, wherein for each new workout added to the workout array, an oldest workout is removed;
- and
- output a belt wear notification based on an aggregation of the weighted average of amperage values for the plurality of speed ranges of the workout array.
