Abstract: A system and a method use dual telemetry for tools located in a wellbore. A first telemetry system and a second telemetry system coordinate communication with the tools. Both the first telemetry system and the second telemetry system may transmit data regarding the tools and/or drilling conditions from the tools to a surface location simultaneously. The first telemetry system or the second telemetry system may communicate with the surface location if communication using the other telemetry system is interrupted. The first telemetry system and the second telemetry system may have a master/slave relationship so that data requests from a specific telemetry system do not interfere with data requests from the other telemetry system.

Abstract: A method and device for remotely detecting structural integrity using reflections or scattering from windows or other portions of a structure. The long geometrical lever arm of a reflection on a building window, when viewed with suitable instruments, produces detectable modulation in the reflected light from minute vibrational changes upon the glass surface, revealing fundamental resonances and structural changes and failure in the building housing the window. By sensing very small changes in intensity and polarization, information may be obtained on fundamental resonances and structural changes, including failure or imminent failure of the structure.
