Claim Text:
1. A method for transferring a 16-bit exit velocity, T, of a projectile from a gun barrel, to an 8-bit fuze controller within the projectile, in order to adjust the detonation delay of the fuze, the method comprising: a. a sensor module that measures the exit velocity, T, of the projectile from the gun barrel and sends a 16-bit data stream of that measurement to an encoder; b. which encoder divides the 16-bit data stream of the exit velocity into two 8-bit data streams (X,Y); c. the first part, X, of the two 8-bit data streams is calculated by the encoder to be equal to T d. the second part, Y, of the two 8-bit data streams is calculated by the encoder to be an 8-bit square root error value equal to T minus the calculated 8-bit integer squared; e. both 8-bit data streams (X,Y) are input to a fuze controller, which then calculates the exit velocity T as the integer, X, squared, plus the 8-bit square root error value; f. the fuze controller then calculates the detonation delay of the projectile.
