Abstract: A method for collaborating remotely that incorporates the use of high-resolution computer imagery, or any other source of high-resolution video, is provided. The method provides for converting high-resolution video or analog RGB computer video into for example, High-Definition Television (HDTV) signals or keep the RGB computer signal in its original format but in digital form. These signals are then compressed, encoded and transmitted over a broadband communication network. At a remote site, the signals are decompressed, decoded and displayed on an HDTV-capable display device. Additionally, the HDTV signals can be reformatted back into their original high-resolution video format or analog RGB computer signals for viewing on an appropriate video display device. If the signals are kept in their original RGB format but in digital form, this last step would not be required, only a conversion back to analog form would be needed.

Abstract: An acoustic borehole well logging method and apparatus for measuring azimuthal anisotropy of a formation traversed by a borehole using at least one multipole transducer. In a preferred embodiment, a dipole wave transmitter and at least one detector sensitive to dipole waves are employed. In an alternative preferred embodiment, a monopole transmitter and at least one multipole detector are employed. In the inventive method, two acoustic wave arrivals are detected, each associated with a different azimuthal orientation relative to the longitudinal axis of the borehole (i.e. each is transmitted by a multipole transmitter oriented at such angle, or is detected by a multipole detector oriented at such angle, or both). The inventive apparatus preferably includes at least one transducer unit including two or more multipole transmitters (or two or more multipole detectors) oriented at different azimuthal angles relative to the tool's longitudinal axis.
