A safety rail monitoring system, and associated methods of operation, for monitoring use of a safety rail that borders a footpath to help prevent injuries while the user traverses the footpath. The safety system includes a sensor system for detecting the presence of a user on the footpath and the presence of a contact by the user on the safety rail. A sensor observation system in communication with the sensor system receives signals indicating whether the user is present on the footpath and whether the user is holding on to the safety rail. If the user is not holding on to the safety rail, the sensor observation system generates an alert signal to the user to remind the user to hold the safety rail. In some embodiments, the safety system may include a barrier that prevents the user from continuing along the footpath without contacting the safety rail.

Systems and methods for monitoring use of rail on a footpath

A projectile includes a component that is highly reflective and configured to reveal the projectile's trajectory when the projectile is fired from a gun and electromagnetic radiation is directed toward the projectile. With the reflective component, one can more easily limit the visibility of the projectile to areas from where the projectile was fired because the reflective component is passive, not active. As the projectile moves down range, the areas behind the projectile are typically where a shooter and/or spotter for the shooter are located, not where an enemy combatant is located. Thus, the trajectory of the projectile is revealed to the people who can use the information to adjust their fire, and remains hidden from the people who could use the information to locate the shooter.
