Robert M. Carangelo has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method and apparatus for signal compression
    Patent number: 5285167
    Abstract: The method and apparatus of the invention effects compression of an analog electrical signal (e.g., representing an interferogram) by introducing into it a component that is a cubic function thereof, normally as a nonlinear negative signal in a feedback loop of an Op Amp. The compressed signal will most desirably be digitized and then digitally decompressed so as to produce a signal that emulates the original.
    Type: Grant
    Filed: July 22, 1992
    Date of Patent: February 8, 1994
    Assignee: On-Line Technologies, Inc.
    Inventor: Robert M. Carangelo
  • Coal-fired heating apparatus and method
    Patent number: 5216981
    Abstract: An aerodynamically cleaned heat-exchanger is used in heating apparatus in which the radiant energy of a dirty fuel, such as coal or char, is efficiently recovered while the exposed heat-exchange components are protected from the deleterious combustion products.
    Type: Grant
    Filed: January 22, 1991
    Date of Patent: June 8, 1993
    Assignee: Advanced Fuel Research, Inc.
    Inventors: Peter R. Solomon, Stephen C. Bates, Robert M. Carangelo, David G. Hamblen
  • Device for blocking of divergent radiation, as in spectroscopy and instrument and method utilizing same
    Patent number: 5170223
    Abstract: The spectrometer permits transmission and emission measurements to be made selectively and accurately without extinguishing the internal radiation source. It includes a device that blocks the divergent source-beam radiation that would otherwise corrupt the emission signal received by the detector.

    Inventors: Robert M. Carangelo, John R. Haigis, Philip W. Morrison, Jr.
  • Method and system for photoconductive detector signal correction
    Patent number: 5136154
    Abstract: A corrective factor is applied so as to remove anomalous features from the signal generated by a photoconductive detector, and to thereby render the output signal highly linear with respect to the energy of incident, time-varying radiation. The corrective factor may be applied through the use of either digital electronic data processing means or analog circuitry, or through a combination of those effects.

    Inventors: Robert M. Carangelo, David G. Hamblen, Carl R. Brouillette
  • System and method for thermogravimetric analysis
    Patent number: 4824790
    Abstract: An instrument for the chemical analysis of coal and other hydrocarbons combines TGA and FT-IR principles, and utilizes helium to carry the volatiles evolved by pyrolysis of the sample into the optical cell of the FT-IR spectrometer. The connection between the TGA furnace and the optical cell is substantially direct and non-impeding to fluid flow, and the carrier gas is preheated to the same temperature as the sample, preferably using a common heating element.

    Date of Patent: April 25, 1989
    Assignee: Advanced Fuel Research, Inc.
    Inventors: Robert M. Carangelo, Peter R. Solomon
  • Method and apparatus for analyzing particle-containing gaseous suspensions
    Patent number: 4652755
    Abstract: The method and apparatus permit analyses, by optical means, of properties of gaseous suspensions of particles, by measuring radiation that is emitted, transmitted or scattered by the particles. Determinations of composition, size, temperature and spectral emittance can be performed either in-situ or by sampling, and Fourier-transform infrared spectrometric techniques are most effectively used. Apparatus specifically adapted for performing radiation scattering analyses, and for collecting radiation from different sources, are provided.
