Athletic performance monitoring with overstride detection
First Claim
Patent Images
1. A system for athletic training comprising:
- a first inertial foot sensor operable for coupling to a first portion of a user foot and configured to generate a first output signal corresponding to a first portion motion, the first portion motion comprising a rearward upward kick and a forward motion in the air in a direction of locomotion;
a second inertial foot sensor operable for coupling to a second portion of the user foot and configured to generate a second output signal corresponding to a second portion motion, the second portion motion comprising a rearward upward kick and a forward motion in the air in the direction of locomotion; and
a processing system configured to compare the first output signal corresponding to the first portion motion to the second output signal corresponding to the second portion motion to identify a desirable stride characteristic or an undesirable stride characteristic.

Abstract
Methods and apparatuses for athletic performance monitoring are disclosed. In one example, a system includes an inertial sensor configured to measure an acceleration in a moving direction of a user foot of a user during locomotion and output an acceleration signal, a memory storing a stride acceleration motion profile, and a processing system configured to process the acceleration signal and the stride acceleration motion profile to identify a reduced user overstride.

9. A method comprising:
-
generating a first sensor output signal responsive to a takeoff rearward kick of a user foot and a landing of a first portion of the user foot in a direction of locomotion; generating a second sensor output signal responsive to a takeoff rearward kick of the user foot and a landing of a second portion of the user foot in the direction of locomotion; and analyzing the first sensor output signal and the second sensor output signal to identify a user overstride. - View Dependent Claims (10, 11, 12, 13)

14. A system comprising:
-
an inertial sensor configured to measure an acceleration in a moving direction of a user foot of a user during locomotion and output an acceleration signal responsive to the acceleration; a memory storing an undesired stride acceleration motion profile; and a processing system configured to process the acceleration signal and the undesired stride acceleration motion profile to identify a reduced user overstride. - View Dependent Claims (15, 16, 17, 18, 19, 20)
