Abstract
Abstract An apparatus which can determine the velocity of a projectile based on distance traveled and time of travel. The apparatus includes a manually operated stopwatch function which can measure elapsed time to at least hundredths of a second, a calculator function which can convert elapsed time and distance traveled by the projectile into velocity of the projectile, and a display to show the velocity. The apparatus can have either a digital or an analog stopwatch function.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
149 words
An apparatus for determining velocity of a projectile, comprising: a) an input means for providing multiple settings of distance traveled by the projectile, b) a digital timing means for measuring elapsed time to at least hundredths of a second, said timing means including means for manually initiating and stopping said timing means, c) a conversion means for determining velocity from said measurement of elapsed time and any one of said multiple settings of distance traveled, said conversion means connected to said input means and digital timing means, d) a means for displaying said determined velocity, said displaying means connected to said conversion means, e) a means to reset said timing and displaying means, said reset means connected to each of said timing means and displaying means, and d) a switching means for switching between settings of distance traveled, said switching means connected to said input means and conversion means.
Claim 2
Independent Claim
149 words
An apparatus for determining velocity of a projectile, comprising: a) an input means for providing multiple settings of distance traveled by the projectile, b) a digital timing means for measuring elapsed time to at least hundredths of a second, said timing means including means for manually initiating and stopping said timing means, c) a conversion means for determining velocity from said measurement of elapsed time and any one of said multiple settings of distance traveled, said conversion means connected to said input means and digital timing means, d) a means for displaying said determined velocity, said displaying means connected to said conversion means, e) a means to reset said timing and displaying means, said reset means connected to each of said timing means and displaying means, and d) a switching means for switching between settings of distance traveled, said switching means connected to said input means and conversion means.
Claim 3
Dependent Claim
14 words
