Low-Profile X-Ray Fluorescence (Xrf) Analyzer

US Patent:
2010022, Sep 9, 2010
Filed:
Mar 5, 2010
Appl. No.:
12/718789
Inventors:
John PESCE - Melrose MA, US
Kenneth P. Martin - Somerville MA, US
Paul G. Martin - Copacabana, AU
International Classification:
G01N 23/223
US Classification:
378 44
Abstract:
A low-profile, hand-holdable, self-contained x-ray fluorescence (XRF) analyzer includes an articulated head. Orientation of the head, relative to a body of the analyzer, may be user adjusted, manually and/or via remote control. A primary x-ray source and an x-ray detector are disposed within the head for articulation therewith. The analyzer may be inserted into a small diameter pipe or other hollow structure, and then the orientation of the head may be adjusted, so a business end of the head is oriented toward a portion of the interior of the pipe or other structure that is to be analyzed. Alternatively, a primary x-ray source and an x-ray detector are disposed within a fixed-orientation head, such that the business end axis of the analyzer is oriented approximately perpendicular to the main axis of the body. Optionally, one or more light sources and cameras may be used to generate images of regions near either of the analyzers to facilitate positioning the analyzer adjacent the sample and, in the case of the articulated head analyzer, orienting the head toward the sample.

Rapid Screening For Lead Concentration Compliance By X-Ray Fluorescence (Xrf) Analysis

US Patent:
8155268, Apr 10, 2012
Filed:
Apr 23, 2010
Appl. No.:
12/766250
Inventors:
John Pesce - Melrose MA, US
Lee Grodzins - Lexington MA, US
Assignee:
Thermo Niton Analyzers LLC - Billerica MA
International Classification:
G01N 23/223
US Classification:
378 45, 378 46
Abstract:
A method is provided for screening lead concentration compliance of objects, particularly consumer products such as toys, using x-ray fluorescence (XRF) analysis. The measured intensity ratio of the characteristic L and L x-rays of lead provides an indication of whether the lead is located primarily in a coating (e. g. , paint) layer on the object, or in a thin or thick bulk material. If the intensity ratio indicates that the lead is located in a coating layer or distributed in a thin bulk material, an areal density of lead is determined from at least one of the characteristic x-ray intensities, and the measured areal density is compared to specified lower and upper limits to determine whether the object is unambiguously compliant, unambiguously non-compliant, or indeterminate.

Measurement Of Lead By X-Ray Fluorescence

US Patent:
2009006, Mar 12, 2009
Filed:
Sep 5, 2008
Appl. No.:
12/205678
Inventors:
Lee Grodzins - Lexington MA, US
John Pesce - Melrose MA, US
International Classification:
G01N 23/223
US Classification:
378 45
Abstract:
A method, instrument, and computer program software product for characterizing a sample with respect to the presence of a specified element, either as a constituent of a surface layer or of the bulk of the sample. Intensities of fluorescent emission at two characteristic emission lines are compared to establish whether the specified element is disposed above the bulk of the sample. In the case where the specified element is disposed above the bulk of the sample, an areal density of the specified element is determined, whereas in the case where the specified element is disposed within the bulk of the sample, a volumetric concentration of the specified element within the sample is determined.

Thermo-Electric Engine

US Patent:
2013011, May 16, 2013
Filed:
Dec 12, 2012
Appl. No.:
13/711831
Inventors:
John Pesce - Melrose MA, US
David Pesce - Amherst MA, US
International Classification:
F03G 6/00
US Classification:
606418
Abstract:
A thermo-electric engine with a working fluid operative in a closed Rankine cycle to enable a harvesting energy from an external source of thermodynamic energy, such as an internal combustion engine or solar energy. The thermo-electric engine can have an evaporator; a turbine fluidically coupled to the evaporator; a heat exchanger comprising a condenser for receiving working fluid from the turbine; a hot liquid input for coupling to a source of heated liquid coolant from an internal combustion engine to the evaporator; a liquid return for returning liquid coolant to the internal combustion engine; a cooling liquid input to the condenser for receiving cooling liquid from a radiator; and a cooling liquid return for returning the cooling liquid to the radiator. Alternatively, a solar energy collector can power a turbine fluidically coupled to the solar energy collector for receiving working fluid.
