Abstract: Apparatus for inhibiting rotation of a projectile tip relative to a longitudinal axis of the projectile. The projectile includes a tip and a jacket with a core. The tip includes a stem that protrudes into said core. The stem includes a plurality of grooves that engage the core. At least one transverse groove inhibits linear motion of the tip along a longitudinal axis of the projectile. At least one longitudinal groove extending along a portion of the length of the tip stem inhibits rotation about the longitudinal axis. In one embodiment, three longitudinal grooves have a spiral shape with the grooves equally spaced about the circumference of the tip stem. In another embodiment, two sets of longitudinal grooves spiral in opposite directions around the tip stem.

Abstract: A method for identifying utility structures is described. The method includes identifying a geographical area for locating the utility structures, receiving images of the geographical area that was identified, performing image processing on the images that were received, identifying the utility structures based on the image processing, and providing location information associated with the utility structures that were identified. Related devices and computer program products are also described.
