Abstract: A social collaboration workflow system embeds social collaboration functionality into the workflow process. The system identifies a location of a user device, and identifying a current activity associated with the user device based on the identified location. The system displays instructions for performing the current activity to a user interface on the user device, and displays an activity feed comprising a set of previously submitted activity feed posts that are related to the current activity to the user interface. The system determines whether the current activity has changed to a new current activity. If the current activity has changed, the system displays instructions for performing the new current activity to the user interface, and displays a new set of previously submitted activity feed posts that are related to the new current activity to the user interface.

Abstract: A breaching apparatus includes an impactor element and a self-contained energy source. The self-contained energy source enables the impactor element to impact a first surface of a structure. The impactor element is configured to transmit a localized shock wave through the structure upon impact. The self-contained energy source is capable of accelerating the impactor element to a velocity sufficient to induce spalling at a second surface of the structure. Multiple breaching apparatuses can be supported by a frame to facilitate simultaneous or successive breaching of the structure. The breaching apparatus can be used in a method to breach a concrete structure.

Abstract: Repeaters for use in amplifying optical data signals transmitted through undersea fiber optic cables are disclosed. Raman amplification schemes using 100 or more pump lasers are integrated into industry standard sized pressure vessels for amplifying optical data signals transmitted through one or more fiber optic pairs. Such repeaters include high density packaging to permit numerous active and passive optical components, as well as significant lengths of optical fiber, to reside within legacy sized pressure vessels.
