Target practice From: Enzo Capretti <e.capretti@avalon.avalon> CC: S. Pham <s.c.pham@elec.avalon>

Thoughts? - Begin forwarded message: From: Enzo Capretti <e.capretti@avalon.avalon> To: Security <security@avalon.avalon> Status on the new equipment? - From: Security <security@avalon.avalon> To: Enzo Capretti <e.capretti@avalon.avalon> The nonlethal devices work, but they don’t fire like conventional weapons. In particular the trajectories are slightly different and most of the security personnel here haven’t had a chance to become used to them. If we had a firing range where we could practice, I think we would feel a lot better about using them. - From: Enzo Capretti <e.capretti@avalon.avalon> To: Security <security@avalon.avalon> According to Lisa there is an electrical engineer in her department who could handle this. I’ll pass it along.

Begin forwarded message: - From: Enzo Capretti <e.capretti@avalon.avalon> To: Security <security@avalon.avalon> Are the practice ranges operational now? - From: Security <security@avalon.avalon> To: Enzo Capretti <e.capretti@avalon.avalon> Yup, they’re working great and we’re already seeing improvements in accuracy. Numbers for you soon. Thanks for sorting that one out.

Description

detect is a simple input that detects when a trainee has fired their weapon. target-x and target-y are simple inputs that detect where the target has been hit. score-1 and score-2 are XBus outputs connected to large numeric displays. Two trainees each take 4 shots and score points depending on where they hit the target. To determine the point value of a shot, find the Euclidean distance (using the Pythagorean theorem) between the hit location and the center of the target, located at (50, 50): distance < 10 4 points 20 <= distance < 30 1 point 10 <= distance < 20 2 points distance >= 30 -2 points The numeric displays should be updated with the trainee's scores as they compete, and should flash 3 times at the end before turning off to indicate that the game is over.
