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.

A Centralizer based Survey and Navigation (CSN) device designed to provide borehole or passageway position information. The CSN device can include one or more displacement sensors, centralizers, an odometry sensor, a borehole initialization system, and navigation algorithm implementing processor(s). Also, methods of using the CSN device for in-hole survey and navigation.

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.
