In March 2017 Patently Apple posted a patent application report titled "Apple Watch Invention Aims to Extend Activities and Monitoring Data for Cyclists." Today, Apple was granted this patent that focuses on calculating wind resistance and touches on heart rate and more.
Apple's granted patent was designed to extend Apple Watch activities and monitoring to include cycling. Improved techniques and systems are disclosed for determining the components of resistance experienced by a wearer of an Apple Watch engaged in an activity such as bicycling or running. By monitoring data using the Apple Watch, improved estimates could be derived for various factors contributing to the resistance experienced by the user in the course of the activity.
In order to improve estimates of the contribution of each of the three portions of total power output, and thus of total power output, a cyclist may wear a wearable device such as an Apple Watch. The wearable device can include a heart rate sensor to provide a series of measurements of cyclist heart rate.
The wearable device can also include motion sensors to collect data about the wearable device's position and orientation in space and to track changes to the wearable device's position and orientation over time.
Apple's patent FIG. 1 noted below is an Apple Watch: FIG. 5 shows the various relevant forces acting on a cyclist during a ride and the relevant velocities of the cyclist; and FIG. 6 shows a method for determining an estimate of wind resistance.
Apple's granted patent 10,699,594 was published today by the US Patent and Trademark Office. You could review our original report for more details and graphics here.
