Abstract: A computer-implemented method for detecting TCP packet losses and expediting packet retransmission is disclosed. The method includes assigning to each packet transmitted or retransmitted a sequential order number; determining from an ACK packet or SACK segment thereof the sequential order number of a received packet; recording the determined sequential order number as a highest order number in case the determined sequential order number is greater than a current received order number, and retransmitting all unacknowledged packets having sequential order numbers less than the highest received order number.

Abstract: In a luminescence detecting apparatus and method for analyzing luminescent samples, luminescent samples are placed in a plurality of sample wells in a tray, and the tray is placed in a visible-light impervious chamber containing a charge coupled device camera. In the chamber, light from the luminescent samples pass through a collimator, a Fresnel field lens, an infrared filter, and a camera lens, whereupon a focused image is created by the optics on the camera. The use of an infrared filter suppresses stray IR radiation resulting from plate phosphorescence (which can result in abnormally high backgrounds and/or alteration of the image received by the camera).

Abstract: In a spectroscopic process a sample for producing a test spectral line or spectrum of at least one component contained in the sample is stimulated and the transmitted and/or emitted electromagnetic rays are used to create the test spectral line or spectrum. In order to improve such a spectroscopic process to such an extent that variations of certain parameters, which alter the shape and/or occurrence of a spectral line, are compensated, a comparison spectral line or spectrum of a known comparison material is produced under substantially the same parameters as the sample. The comparison spectral line or spectrum is compared with an ideal comparison spectral line or spectrum in order to calculate a transfer function, andthe transfer function is applied to the test spectral line or spectrum in order to calculate a corrected test spectral line or spectrum.

Abstract: A method for obtaining at least one calibration filter for a Mass Spectrometry (MS) instrument system. Measured isotope peak cluster data in a mass spectral range is obtained for a given calibration standard. Relative isotope abundances and actual mass locations of isotopes corresponding thereto are calculated for the given calibration standard. Mass spectral target peak shape functions centered within respective mass spectral ranges are specified. Convolution operations are performed between the calculated relative isotope abundances and the mass spectral target peak shape functions to form calculated isotope peak cluster data. A deconvolution operation is performed between the measured isotope peak cluster data and the calculated isotope peak cluster data after the convolution operations to obtain the at least one calibration filter. Provisions are made for normalizing peak widths, combining internal and external calibration, and using selected measured peaks as standards. Aspects of the methods are applied to other analytical instruments.

Abstract: A luminescence detecting apparatus and method for analyzing luminescent samples is disclosed. Luminescent samples are placed in a plurality of sample wells in a tray, and the tray is placed in a visible-light impervious chamber containing a charge coupled device camera. The samples may be injected in the wells, and the samples may be injected with buffers and reagents, by an injector. In the chamber, light from the luminescent samples pass through a collimator, a Fresnel field lens, a filter, and a camera lens, whereupon a focused image is created by the optics on the charge-coupled device (CCD) camera. The use of a Fresnel field lens, in combination with a collimator and filter, reduces crosstalk between samples below the level attainable by the prior art. Preferred embodiments of the luminescence detecting apparatus and method disclosed include central processing control of all operations, multiple wavelength filter wheel, and robot handling of samples and reagents. Preferred embodiments of processing software integrated with the invention include elements for mechanical alignment, outlier shaving, masking, manipulation of multiple integration times to expand the dynamic range, crosstalk correction, dark subtraction interpolation and drift correction, multi-component analysis applications specifically tailored for luminescence, and uniformity correction.

Abstract: Constituents such as oxy- and deoxy-hemoglobin are monitored non-invasively in an animal organ such as a brain with a spectrometric instrument by passing radiation through the organ. Concentrations are computed from the spectral intensities and from a statistical correlation model. To predetermine the correlation model, the procedures are effected for a plurality of organs of a same type with each organ having established concentrations of the selected constituents, and the correlation model is statistically determined from the concentrations and corresponding intensities. For more accuracy computations are normalized to path length which may be determined by utilizing several discrete wavelengths with RF modulations.
