摘要： A system for reducing signal interference in modulated signal communication includes a measurement processor. The measurement processor measures amplitudes of noise components of a received amplitude modulated signal prior to demodulation. The measurement processor also identifies a frequency of a noise component having an amplitude larger than the amplitude of another noise component. A carrier frequency generator generates a carrier frequency substantially at a harmonic of the identified noise component. The carrier frequency is used to generate and demodulate the amplitude modulated signal.

摘要： A method of monitoring gas in a downhole environment is discussed which provides downhole a mid-infrared light emitting diode, operates the diode to transmit respective infrared signals on a first optical path extending from the diode through a downhole gas sample and a second optical path extending from the diode through a reference gas sample, detects the transmitted infrared signals, and determines the concentration of a component of the downhole gas sample from the detected signals.

摘要： A spectral reflectance sensor including: a light source for emitting a modulated beam of red light; a light source for emitting a modulated beam of near infrared light; a receiver for receiving reflected light produced by either the red source or the near infrared source; a receiver for receiving incident light from either the red source or the infrared source; a signal conditioner responsive to the modulation such that the signals produced by the receivers in response to reflected and incident light from the source can be discriminated from signals produced by ambient light; and a microprocessor having an input such that the microprocessor can determine the intensities of incident red light, reflected red light; incident near infrared light; and reflected near infrared light. From these intensities, and by knowing the growing days since emergence or planting, the sensor can calculate the mid-growing season nitrogen fertilizer requirements of a plant.

摘要： A spectroscopic system for quantifying in vivo concentration of an absorptive pigment in biological tissue includes an oscillator for generating a first carrier waveform of a first frequency on the order of 108 Hz, a light source for generating light of a selected wavelengths modulated by the carrier waveform, and a detector for detecting radiation that has migrated over photon migration paths in the tissue from an input port to a detection port spaced several centimeters apart. The wavelength is sensitive to concentration of an absorptive pigment present in the tissue. A phase detector compares the detected radiation with the introduced radiation and determines therefrom the phase shift of the detected radiation. A processor quantifies the concentration of the absorptive pigment by calculating a value of the absorption coefficient.

摘要： An oximeter that measures both the total hemoglobin concentration in whole, undiluted blood and the percentage of the hemoglobin saturated with oxygen. The oximeter uses red and infrared light-emitting diodes to illuminate a capillary tube filled with a sample of whole, undiluted blood. Light scattered by the blood travels a short distance down the length of the capillary tube and reaches a photodetector, the output of which is amplified, digitized, and fed to a microprocessor. The microprocessor computes the total hemoglobin concentration as a nonlinear monotonic function of the infrared light intensity. Oxyhemoglobin saturation is computed from the ratio of the logarithms of the intensities of red and infrared light. The invention provides a measurement of oxygen saturation without calibration shifts present in other oximeters due to fluctuations in total hemoglobin concentration. In addition, the present invention is accurate over a wide range of oxygen saturation, and the blood samples are not diluted or hemolyzed and can thus be preserved for further analysis.

摘要： A bundle of fiber-optic sensors that resist breakage, for use in measuring pH, CO.sub.2, and O.sub.2 concentration, and a method of making the same. Three otpical fibers are enclosed in a common polyimide sheath and extend parallel to one another toward a distal end of the sensor, where they are bonded together in a mutually supportive array. At the distal end of one of these optical fibers is disposed a pellet comprising a CO.sub.2 analyte indicator molecule codissolved within a polymer matrix. A thin reflective surface of gold foil is provided on the pellet such that incident light transmitted through the optical fiber and polymer matrix is reflected back into the optical fiber. The CO.sub.2 polymer matrix absorbs light of a given wavelength to an extent dependent upon the level of CO.sub.2 present. Similarly, on the distal end of a second optical fiber is disposed a pH pellet comprising a pH analyte indicator matrix with a thin reflective gold foil attached for reflecting light that has passed through the pH analyte indicator matrix back into the optical fiber. The pH analyte indicator matrix absorbs light of a given wavelenth to an extent dependent upon the hydrogen ion concentration (pH level) of a surrounding fluid. The third optical fiber is used for measuring oxygen concentration. An O.sub.2 indicator matrix covers the distal ends of at least two of the three optical fibers; however, at least a portion of the pH optical fiber and the pH pellet are free of the O.sub.2 indicator matrix, which is hydrophobic. The oxygen indicator matrix phosphoresces for an interval of time that decreases in proportion to the surrounding oxygen gas concentration. The phosphorescent and reflected light signals are transmitted to light detectors through the optical fibers for comparison to reference signals, so that the analyte concentrations can be determined.
