    摘要： A system for imparting and detecting mechanical energy includes a projectile and a hollow tube allowing the projectile to move therein. A portion of the projectile is allowed to emerge from one end of the tube and thereby transfer mechanical energy to a receiving entity, e.g., a wound roll of material. An actuator drives the projectile through the tube, and a first sensor detects when the protruding portion of the projectile extends from the tube to make contact with, for example, the core of the wound roll to start a timing sequence. A second sensor detects the arrival of the mechanical energy at, for example, the roll surface so that a comparison can be made between the start and end times.
