  • Patent number: 6803578
    Abstract: A method for identification and partial-pressure determination of two gases in an unknown anesthesia gas mixture comprising n possible gases by measuring the infrared optical radiation, transmitted through the gas mixture, that passes through m filters having different transmission wavelength ranges, in which n is a number greater than 2 and m is a number less than n. The method evaluates the exit intensities, measured after passage through the filters, of the infrared optical radiation transmitted through the unknown gas mixture in such a way that with three filters, for instance, two gases in an unknown gas mixture comprising five possible gases can be identified, and their partial pressures can be determined. By dividing the partial pressures by the total pressure, it is optionally also possible to determine the concentration of the gases.

  • Patent number: 6797961
    Abstract: An X-ray sensing array substrate that includes a storage capacitor having first and second capacitor electrodes and a pixel electrode over the storage capacitor. One of the capacitor electrodes contacts a drain electrode of a thin film transistor through a first contact hole in an insulating layer. The pixel electrode contacts that capacitor electrode through a second contact hole through a second insulting layer. Therefore, the drain electrode is connected to the storage capacitor through only one contact, while the pixel electrode contacts the storage capacitor through only one contact. This reduces the drain electrode to capacitor resistance, reduces the voltage drop, and increases the sensitivity of the array.

  • Patent number: 6787761
    Abstract: High-intensity, spiked noise is reduced in chromatography-mass spectrometry data by applying a nonlinear filter such as a moving median filter to the data. The filter is applied to individual mass chromatograms, plots of ion abundance versus retention time for each detected mass-to-charge ratio, and the filtered chromatograms are combined to form a filtered total ion current chromatogram. Standard linear filters are not effective for reducing noise in liquid chromatography-mass spectrometry (LC-MS) data because they assume a normal distribution of noise. LC-MS noise, however, is not normally distributed.

  • Patent number: 6784423
    Abstract: A method for determining the shape and size of particles and their constituent elements is disclosed. Particle ions are accelerated through a mass spectrometer useful in identifying the source particle of the resulting ions. By measuring the time-varying intensity of the identified ions as they strike a detector, a plot of the intensity of the ions over time is obtained for each ionized particle. The size of each ionized particle is determined by measuring a time span corresponding to the width of the peak of this plot. If the detector is a phosphor detector, the shape of the particle may be determined by using a high-speed camera to capture cross-section images of the ion-induced light pattern at closely-spaced successive moments in time. Alternatively, the intensity of ions striking the detector along at least one lateral dimension may be detected.

  • Patent number: 6774362
    Abstract: There is disclosed an analytical method capable of performing an analysis in electron microscopy by directing an electron beam at set analysis points wherein a reference image is displayed on a monitor and a user selects plural analysis points within the image. The specimen stage is returned to the approximate position where the reference image was obtained and a new image is obtained. At this time, the newly obtained image does not completely agree in position with the reference image due to accuracy of movement of the stage. The two images are supplied to a deviation amount calculator, which, in turn, compares the images and finds the amount of deviation of the newly obtained image from the reference image.

  • Patent number: 6768824
    Abstract: The specification describes tuning devices for controlling variable polarization dependent loss. These are based on the discovery that essential properties of TAP LPGs can be realized in birefringent fibers, i.e. in fibers where the propagation constants of the core and/or cladding modes are different for different SOPs of light. This yields a device that exhibits broadband loss of varying amounts for different SOPs of input light. Thus, the building block for a broadband in-fiber polarizer is realized. Tuning mechanisms are applied to vary the relative coupling magnitudes for two orthogonal SOPs of light in the device. This yields a polarizer in which the polarization is dynamically tuned.
