Abstract: A device may include a projectile body configured to follow a ballistic trajectory comprising. A device may include a nose section terminating in a distal end and shaped at a proximal end to provide a smooth transition between a proximal cross-section of the nose section and a cross-section of a body portion, wherein the distal end comprises a smaller cross-sectional area than the proximal end. A device may include the body portion having a shape of a lifting body configured to generate lift, wherein the body portion has a non-circular cross-section over a portion of its length.

Abstract: A process for simulating an expert experience comprises playing an expert simulation for a user, where the expert simulation is a processed video with tagged objects and untagged objects. During playback, a user may make an unprompted selection of an object in the video of the expert simulation, and the unprompted selection is received. In response to receiving the unprompted selection from the user, an entry interface for the user to enter in a freeform rationale is provided. After the user enters a freeform rationale through the entry interface, the freeform rationale is received. An expert rationale associated with a tagged object is displayed. Further, a process for creating the expert simulation comprises receiving raw video and superimposing a grid onto the raw video. An author tags objects within the video spatially, temporally, or both. Further, freeform data (e.g., an expert rationale) is associated with the tagged object.

Abstract: A method and apparatus of forming a reclosable bag of flexible film wherein the bag has confronting side walls joined by seams at its edges and confronting rib and groove fastener strips at the top edge with the strips joined to the inner faces of the bag walls by bonding layers which have a predetermined width such that when a spot seal is formed at the ends of the strips, leakage is prevented between said strip ends so that the interconnecting profiles of the strips are sealed in permanent alignment. The flattened melted material of the spot seals is secured to the bag walls by the bonding layer and the predetermined width of the bonding layer is wider than the spot seals.
