Patent Images
1. A speed and distance measuring device for an athlete in an athletic event in competition and/or training, the speed and distance measuring device comprising:
- a data storage means;
a user input for saving at least one event-based parameter in the data storage means;
at least one accelerometer for determining a first speed and distance estimate for the athlete during the competition or training;
a global positioning system for determining a second speed and distance estimate; and
wherein a combination of the first and second speed and distance estimates determines a real-time speed and distance measurement of the athlete for comparison with the event-based parameter.

Abstract
A dynamic motion and distance measuring device for estimating and measuring speed and distance covered by a subject engaged in an athletic endeavor and more particularly to measuring and estimating the speed and distance and providing a relative indication of a measured speed and distance to an optimal speed and distance and/or time including finish time of the subject engaged in an athletic event, even where the event is occurring in changing environment or terrain conditions where remote data collection and signal reception is inconsistent and variable.

11. A method of measuring the speed and distance of an athlete in an athletic event, the method comprising the steps of:
-
providing a data storage means for storing data relating to the athletes dynamic motion in a plurality of predefined physical states; inputting prior to a start of the athletic event a first event-based parameter to be saved in the data storage means; determining a first nominal speed and distance measurement for the athlete during the athletic event by a first speed and distance measurement device; determining a second speed and distance measurement according to a second speed and distance measurement device; and wherein a combination of the first and second speed and distance measurements determines a real-time speed and distance of the athlete for comparison with the event-based parameter and a result of the comparison is output to the athlete via at least one of a visual and audible display. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
