Abstract: Various communication systems may benefit from enhanced reception methods. For example, various transponders and surveillance systems may benefit from reception methods that can distinguish between overlapping pulses from multiple sources. A method can include receiving, at an antenna, a first series of pulses from a first source. The method can also include receiving, at the antenna, a second series of pulses from a second source. The first series and the second series can at least partially overlap each other. The method can further include de-interleaving the first series from the second series using at least one non-time-domain technique.

Abstract: A spreading tool comprises a first arm having a pivot end and an engagement end and a second arm having a pivot end and an engagement end. A connector combines the pivot end of the first arm with the pivot end of the second arm for rotational movement between a closed position and an open position. A handle is combined to the second arm and positioned apart from the connector so that the connector is positioned between the handle and the engagement end of the first arm and the engagement end of the second arm for the entire path of travel between the open and closed positions.
