主权项

1. A system comprising:
a receiver; an ear piece communicatively coupled to the receiver and configured to provide audible output to a user's ear; a microphone sensor communicatively coupled to the receiver, and configured to generate data for determining a contact and a lack of contact with the ground; a sensing unit coupled to an article of footwear, the sensing unit comprising a force sensitive resistor that includes inter-digitated electrodes over a semi-conductive polymer ink and that is configured for measuring changes in resistance as a function of force and a transmitter configured to wirelessly communicate with the receiver, wherein the sensing unit is configured to:
detect movement of the article of footwear over ground due to locomotion of a user while walking or running;generate performance data based on the detected movement; andcause the transmitter to wirelessly transmit the performance data to the receiver, wherein the ear piece is configured to output audio information that continually informs the user of real time speed.
