Abstract: Methods and apparatus for measuring a phase fraction of a flow stream are disclosed. An infrared phase fraction meter includes a light source for emitting into a flow stream infrared radiation that includes first and second wavelength bands. The first wavelength band substantially transmits through first and second phases of the flow stream and is substantially absorbed by a third phase. In contrast, the second wavelength band is substantially absorbed by the second phase relative to the first and third phases. One or more detectors simultaneously detect attenuation of the first and second wavelength bands upon the infrared radiation passing through at least a portion of the flow stream, and a phase fraction of the second phase is determined based on the attenuation. As an example, the first, second and third phases are gas, water and oil, respectively, produced from a well.

Abstract: An automatic optical power management system for use with an optical communications system includes a light source residing in a first circuit pack and adapted to emit light at a nominal power level only absent receipt of an indicator signifying a loss of signal resulting from a fiber discontinuity relating to the first optical fiber, wherein the nominal power level is of sufficient magnitude to violate laser safety guidelines in the event of the fiber discontinuity. A redundant detection system includes a first optical detector residing in the first circuit pack, and a second optical detector residing in a second circuit pack that is optically adjacent to the first circuit. A redundant response system communicates an indicator signifying loss of signal from the first and second optical detectors to the light source upon detection of loss of signal by either detector.

Abstract: A method and apparatus for utilizing a digital computer to print characters of multiple fonts, both textually and graphically, on a single printer from within a single document [is disclosed]. Existing computer programs provide the capability of printing pre-defined textual characters or graphical characters separately, but not in an integrated manner as is disclosed. Thus, the invention enables printing of a variety of mixed characters, such as international alphabetic characters and complex mathematical characters, within a single document.
