1. A method of determining an instantaneous speed of an arrow shot from a bow having a bow string, the method comprising acts of:
- determining a time-of-flight of the arrow, at least in part, by employing an apparatus included in the arrow to determine a moment in time when a start of a free-flight of the arrow occurs, the start of the free-flight occurring when a proximate end of the arrow reaches substantially a neutral position of the bow string;
determining a distance between a location from which the arrow is loosed and a location of a target-face; and
determining the instantaneous speed of the arrow by employing at least each of;
a) the time-of-flight; and
b) the distance.

Abstract
In one aspect, a method of determining an instantaneous speed of an arrow, includes determining a time-of-flight of the arrow; determining a distance between a location from which the arrow is loosed and a location of a target-face; providing, with an apparatus included in the arrow, data from at least a portion of a free flight of the arrow; and determining the instantaneous speed of the arrow for at least one point of the free-flight by employing each of: a) the time-of-flight; b) the distance; and c) at least some of the data provided by the apparatus.

8. A method of analyzing a flight of an arrow, the arrow including an arrow shaft, the method comprising:
-
collecting data, with a sensing system included in the arrow, during at least one flight of the arrow; and performing frequency analysis on the collected data to determine a vibration of the arrow shaft. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)

22. A method of determining an instantaneous speed of an arrow shot from a bow having a bow string, the method comprising acts of:
-
determining a time-of-flight of the arrow, at least in part, by employing an apparatus included in the arrow to determine a moment in time when a start of a free-flight of the arrow occurs following a launch phase, the start of free-flight occurring when a proximate end of the arrow reaches substantially a neutral position of the bow string; determining a distance between a location from which the arrow is loosed and a location of a target-face; and determining the instantaneous speed of the arrow by employing at least each of;
a) the time-of-flight; and
b) the distance. - View Dependent Claims (23)
