Abstract: The invention relates to a pipe system comprising a pipe, a gas sensing station and a remote output system. The pipe comprises a pipe gas cavity, such as an annulus, extending lengthwise in part or all of the length of the pipe; the gas sensing station comprises a sensing gas cavity which is in gas communication with the pipe gas cavity: The sensing gas cavity comprises a photoacoustic spectroscope. The pipe system comprises at least one optical feeding fiber for feeding light to the photoacoustic spectroscope and a transmission path for transferring a signal from the photoacoustic spectroscope to the remote output system, the transmission path from the gas sensing station to the remote output system is an optical transmission path. The pipe may for example be a flexible pipe e.g. an umbilical or a pipe for the transportation of crude oil from a well to an off shore or on shore station, for example a ship or a platform. The gas sensing station may be integrated in the pipe, e.g. in an end fitting or it may be an external gas sensing station. According to a high security embodiment of the invention it is desired that all energy transported between the remote output system and the gas sensing station is in the form of optical energy e.g. transported in one or more optical fibers. This embodiment provides a very safe and simultaneously well functioning system, with reduced risk of igniting burnable fluids and simultaneously with a high signal-to-noise quality.

Abstract: An in vivo implantable sensor (10) obtains spectra of body fluid constituents, and processes the spectra to determine the concentration of a constituent of the body fluid. The sensor includes an optical source (12), and detector (16). The source emits light at a plurality of different, discrete wavelengths, including at least one wavelength in the infrared region. The light interacts with the body fluid and is received at the detector. The light at the plurality of different wavelengths has a substantially collinear optical path through the fluid with respect to each other. When measuring fluid constituents in a blood vessel (14), such as blood glucose, the light at the plurality of different wavelengths is emitted in a substantially single period of time. The spectra are corrected for artefacts introduced from extraneous tissue in the optical path between the source (12) and the detector (16).

Abstract: Instrument (16) for detecting single airborne particles, measuring their concentration, includes transmitting optical fiber (28) optically connected to light source (80) at one end, and collecting optical fiber (30) connected to photodiode (84) at one of its ends. Respective opposite ends of the optical fibers are polished smooth and flat potted into a rigid probe head (46), facing each other and separated by air gap (74). Some of the light crosses gap (74) between optical fibers (28, 30) and reaches detector (84), defining a particle sensing volume (76). Particles passing through this volume are optically detected. The device has simple optics, requiring no lenses or mirrors. The transmitting and collecting fibers, and the air gap, form a well defined and repeatable sensing volume (76). The particle size threshold in the electronics is a percentage of the light to the detector which allows it to remain in calibration when the amount of light through the probe changes.

Abstract: Radiant energy is transmitted to a probe element including an interior conical reflecting surface and a fluid sample chamber. Portions of the light which have been transmitted, partially attenuated, or scattered by a fluid sample in the sample chamber are directed by at least a portion of the interior conical reflecting surface to means for collecting the transmitted, partially attenuated, or scattered light. A stilling valve incorporated into the probe element enables elimination of entrained gas bubbles from the chamber. A specific application of the probe is disclosed in which a titration analyzer is combined with electro-optic signal conversion and processing circuits and a probe according to the invention to provide titration colorimetric endpoint determination in measuring the free fatty acid content of a fluid such as an edible oil or fat.

Abstract: The system for sensing ions in aqueous solution such as an electroplating bath includes a light source (18) which delivers light including a selected wavelength through a series of optical fibers (20, 24, 26, 32) to probe (14). The probe is partially immersed in the solution (12) and the light is delivered through the solution in the space (94) between prisms (82, 92). The return light is conducted by optical fibers (32, 38) to detector or opto-electronic transducer (44). A portion of the original light is diverted by splitter (22) through fiber (42) to opto-electronic transducer (46) so that a comparison of the signals determines the amount of light in selected wavelength is absorbed in the solution due to ions thereon. The signal processing unit (40) is preferably enclosed in an electromagnetic protected area (16) to avoid the adverse EMI and corrosive atmosphere effects near the electroplating tank (10).
