Patent Number Title Of Patent Date Issued
6420709 Methods of minimizing scattering and improving tissue sampling in non-invasive testing and imagi July 16, 2002
An improved method and apparatus for use in optical testing of concentration in samples has been developed. The apparatus restricts the solid angle of illumination and the solid angle of detection to eliminate a high proportion of the scattered radiation while allowing the ballistic
6064065 Methods of minimizing scattering and improving tissue sampling in non-invasive testing and imagi May 16, 2000
An improved method and apparatus for use in optical testing of concentration in samples has been developed. The apparatus restricts the solid angle of illumination and the solid angle of detection to eliminate a high proportion of the scattered radiation while allowing the ballistic
6028311 Rapid non-invasive optical analysis using broad bandpass spectral processing February 22, 2000
The present invention provides a generally applicable apparatus and method for achieving measurements of a constituent in a sample. This is achieved by employing a detection means having a plurality of detectors responsive to radiation in a selected region of the spectrum, e.g., the infr
6008057 Immunoassay system December 28, 1999
Disclosed is a method of assaying, in assay apparatus, for at least the ligand intended to be used to assay analyte in a sample, with which analyte the ligand will specifically bind. The method provides a product in which a ligand is labeled with a detectable tag and is immobilized on
5818048 Rapid non-invasive optical analysis using broad bandpass spectral processing October 6, 1998
The present invention provides a generally applicable apparatus and method for achieving measurements of a constituent in a sample. This is achieved by employing a detection means having a plurality of detectors responsive to radiation in a selected region of the spectrum, e.g., the infr
5818044 Non-spectrophotometric measurement of analyte concentrations and optical properties of objects October 6, 1998
Improvement methods and apparatus for determination of optical properties of objects have been developed. The apparatus and methods of the invention provide an analog of color perception of human vision, preferably in the near infrared region, replacing spectrophotometers and narrow band
5672875 Methods of minimizing scattering and improving tissue sampling in non-invasive testing and imagi September 30, 1997
An improved method and apparatus for use in optical testing of concentration in samples has been developed. The apparatus restricts the solid angle of illumination and the solid angle of detection to eliminate a high proportion of the scattered radiation while allowing the ballistic
5434412 Non-spectrophotometric measurement of analyte concentrations and optical properties of objects July 18, 1995
Improvements in non-invasive detection methods for glucose and other constituents of interest in a sample have been developed. The apparatus and methods of the invention provide an analog of color perception of human vision, preferably in the near infrared region, replacing spectroph
5424545 Non-invasive non-spectrophotometric infrared measurement of blood analyte concentrations June 13, 1995
A new non-invasive non-spectrophotometric method for measuring the blood concentration of analytes such as glucose has been developed. The apparatus and methods of the invention exploit analogies with colorimetry and color perception to extract concentration measurements from the global
5321265 Non-invasive testing June 14, 1994
A new non-invasive detection method for glucose and other constituents of interest in a sample has been developed. The apparatus and methods of the invention provide an analog of color perception of human vision, preferably in the near infrared region, replacing spectrophotometers and
4909990 Immunoassay apparatus March 20, 1990
An assay apparatus employing total internal reflection of excitation radiation at the interface between a replaceable optically conductive rod or fiber and a surrounding liquid phase of lower index of refraction. Immobilized on the surface of the fiber is a component of a complex formed
4716121 Fluorescent assays, including immunoassays, with feature of flowing sample December 29, 1987
An assay method and apparatus employing total internal reflection of excitation radiation at an activated region on the surface of an optically conductive rod or fiber surrounded by a liquid phase of lower index of refraction, so as to excite into fluorescence fluorophores in the liquid
4582809 Apparatus including optical fiber for fluorescence immunoassay April 15, 1986
A method and apparatus for fluorescent immunoassay utilizes total internal reflection at the interface between a solid phase and a liquid phase of lower index of refraction to produce an evanescent wave in the liquid phase. The solid phase is arranged and illuminated so as to provide
4558014 Assay apparatus and methods December 10, 1985
An assay apparatus and methods employing total internal fluorescence to define a thin observed volume of a multi-phase suspension from which the suspended phase, because of its size and shape, is substantially excluded. Observations of the fluorescence of a known quantity of fluorescent
