A method includes obtaining multiple data items from multiple heterogeneous data sources, where the multiple data items relate to an unmanned aerial system (UAS) flying in an area. The method also includes processing the multiple data items using a machine learning algorithm to determine a threat level of the UAS to one or more targets in the area. The method further includes outputting the threat level of the UAS for review by a user.

Threat assessment of unmanned aerial systems using machine learning

The system includes a stance and stride chart adapted to lie flatly on the ground and having indicia thereon indicating home plate and the proper location for a batter's feet as he stands adjacent home plate in preparation for taking a stride during a batting swing. Further included is a ball toss device adapted to be positioned forwardly adjacent the stride chart and operable to loft a ball gently through the strike zone above the plate for hitting by the batter as he completes the swing. A catching net may be positioned forwardly of the chart to collect batted balls. The ball toss device is operable to loft a supply of balls sequentially and at spaced intervals toward the strike zone and has the capability of adjustment for accommodating either hardballs or larger diameter softballs. An adjustment is also provided which enables the loft of the balls being propelled from the device to be varied substantially in order that the device may be used to propel ground balls toward a fielder instead of lofting them toward a batter.

A simple and efficient clip structure and method for fastening snack food bags closed is provided which allows an opened bag to be tightly reclosed. The closure clip is preferably integral and has three elongated, side-by-side laterally spaced apart bag-engaging members (a pair of adjacent long members and a single, outer short member). In use, the flattened upper end of a bag is inserted between the long members, and the clip is rotated axially to form a coil; at this point, the clip is partially withdrawn from the coil until the short member is clear of the bag, whereupon the clip is pushed back towards its original position, but with the short member located outside of the coil for locking the bag against uncoiling. Snack foods or the like can thus be stored in a previously opened bag secured by the closure clip without the food losing its freshness, palatability or nutritional value.
