Abstract
A location measurement system including a GPS receiver for attachment to a person and for determining earth location of the person; a display for attachment to the person; memory for storing map data; a processor configured to process earth location and the map data to instruct display the person's current location with a map on the display.
Claims18
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;
- and
- cause 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.

A method comprising:
- detecting, by a 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 being coupled to an article of footwear, ground movement of the article of footwear over ground due to locomotion of a user while walking or running;
- detecting airtime movement using data sensed by a microphone, wherein the data indicates the lack of contact with the ground based on vibration being reduced during the at least one time interval;
- generating performance data based on the detected ground movement and airtime movement;
- wirelessly transmitting, by a transmitter, the performance data to a receiver that is communicatively coupled to an ear piece;
- and
- outputting, by the ear piece, audio information that continually informs the user of real time speed.
