  • Patent number: 9998636
    Abstract: The present invention is a method of removing the illumination and background spectral components thus isolating spectra from multi-spectral and hyper-spectral data cubes. The invention accomplishes this by first balancing a reference and sample data cubes for each spectra associated with each location, or pixel/voxel, in the spatial image. The set of residual spectra produced in the balancing step is used to obtain and correct a new set of reference spectra that is used to remove the illumination and background components in a sample data cube.

  • Patent number: 9435687
    Abstract: The present invention is a method of obtaining and isolating sample spectra from a wide wavelength illumination source without the use of filters. The method obtains the combined sample and illumination spectra of a sample and removes the illumination spectrum from the combined spectrum. This is accomplished by obtaining both the combined sample/illumination spectrum and the illumination spectrum separately at the same time and under the same environmental and instrument conditions. The illumination spectrum is then subtracted, wavelength by wavelength from the combined sample/illumination spectrum, leaving the pure sample spectrum which may a single spectrum or combination of two or more spectra from different types and/or compounds in the sample.

  • Publication number: 20110017273
    Abstract: A system for concentrating solar energy comprising a collector consisting of a number of reflective panels, a receiver which absorbs reflected energy, a working fluid which absorbs the energy, a highly transmissive cover and internal colorings or coatings to collect indirect radiation, and a solar tracking system to maintain reflector orientation. Optional photo-voltaic panels could also be used for providing electrical energy and are kept at near ambient temperatures. Under normal conditions, solar energy is concentrated by reflectors on the receiver, which transfers the energy to a working fluid which is then used for either hot water heating, desiccant drying for a solar air conditioner, or as a power source. Additional energy is collected from indirect sources using the greenhouse effect.

  • Patent number: 5906104
    Abstract: A heat transfer system including mechanical and electrical components for use with a mechanical air conditioning system to enable the system to efficiently reject heat to a water source, such as a pool or spa while simultaneously cooling an interior space. The air conditioning system incorporates three primary heat transfer coils in a mechanical refrigeration cycle to provide comfort cooling to an interior space while rejecting heat to either the atmosphere or a water source, such as a swimming pool. In an alternate heat pump embodiment, the system is capable of operating in an additional mode to absorb heat from the atmosphere and reject heat to the interior space.

  • Patent number: 5450190
    Abstract: A coded hidden identification is provided for a selected printable item by providing a coded printing composition based on adding to and substantially uniformly mixing a selected number of populations of microparticles with a printing composition, said microparticles being normally invisible to the human eye and each such population having a group of microparticles of similar size, shape or color to form a combination of highly uniform and unique properties, the printing composition adapted for use in a printing machine, such as a photocopy or laser printing machine cartridge, and printing items with the coded printing composition so as to transfer the microparticles to the item. The microparticles may be characterized by a number of detectable properties, or a combination thereof, which are not detectable by the human eye to provide the coded hidden identification.

  • Patent number: 5314824
    Abstract: A method of setting up a flow cytometer using microbeads fluorescing at a plurality of wavelengths, control cells for each of said wavelengths, certified blank microbeads. The blank microbeads are run and the PMT voltages are adjusted so that the blank microbeads are on scale on the flow cytometer. The control cells are run and the photomultiplier tube voltages are adjusted so that the single population falls in selected channels. The fluorescent microbeads are run on the flow cytometer and the Target Channels for the flow cytometer are determined.

  • Patent number: 5093234
    Abstract: A kit of highly uniform size microbead standards for flow cytometer alignment, compensation, and/or calibration, comprising a blank microbead population and/or an auto-fluorescent microbead population, together with two or more series of calibrated microbead populations labeled with fluorescent dye(s) which (i) prior to fluorescent dye(s) labeling, match the fluorescence spectra and fluorescence intensity of the blank and/or autofluorescent microbead population, and (ii) after fluorescent dye(s) labeling, match the fluorescence spectra and fluorescence intensity of fluorescently labeled samples to be measured on the flow cytometer. Also disclosed is a corresponding method to align, compensate, and/or calibrate a flow cytometer so as to make measurements on samples comparable and independent of the specific instrument and instrument settings.

  • Patent number: 5084394
    Abstract: The use of a combination of calibrated microbead populations with one or more calibrated biological cell populations to correct calibration of a flow cytometer for size and fluorescence intensity determinations of biological cell samples. The use of calibrated biological cells permits correction for factors related to the instrument and calibration microbeads so long as the excitation and emission spectra of the calibration microbeads, the calibration cells and the cell samples are all the same, respectively.

  • Patent number: 5073497
    Abstract: A flow cytometer reference standard containing a highly uniform microbead population, wherein each microbead has the same multiple fluorescent labels as the other microbeads and as the samples to be measured. Target conditions are set for the sample after alignment of the flow cytometer. The microbead reference standard is used to determine peak channels (target channels) for each parameter. The target conditions may be reestablished for later uses of the flow cytometer with the same type of samples by using the microbead reference standard to adjust the flow cytometer so that the microbead peak channels fall in the originally determined target channels.

  • Patent number: 4918004
    Abstract: A method for calibrating a flow cytometer or fluorescence microscope in terms of number of binding antibodies as a function of fluorescence intensity value measured on the flow cytometer or fluorescence microscope, and subsequent measuring of a sample to which the antibodies are bindable. Also disclosed is a microbead calibration kit for carrying out the calibration method of the invention. The disclosed calibration methodology provides a direct relationship between instrument response and numbers of binding antibodies, independent of the fluorochrome employed to label the samples being measured. The method has utility in monitoring the status of an antigenic cellular condition in which the number of antibodies binding to successively obtained cellular samples is determined, to establish the progressionary character of the antigenic cellular condition, in a host from which the cellular samples are taken.

  • Patent number: 4868126
    Abstract: A method of calibrating a flow cytometer or fluorescent microscope is based on a set of highly uniform microbeads associated with a fluorescent dye in such a way that the microbeads have the same excitation and emission spectral properties as the samples which are to be measured. The calibration values of the microbeads are plotted against the relative fluorescence intensity peak channel or intensity reading for each microbead in the set. From this calibration plot, the relative fluorescence intensity peak channel or intensity reading of the sample is translated into equivalent soluble fluorescent dye molecules per sample particle. The calibration values of the standard microbeads are determined against solutions of the dyes.
