20110110493 | Determination of Composition of Liquids - A method of and apparatus for obtaining radiation transmission data from a liquid in such manner that allows some data about relative proportions of constituent ingredients to be derived is described. A radiation source and a radiation detector system able to resolve transmitted intensity across a plurality of frequencies within the spectrum of the source are used to produce transmitted intensity data for each such frequency. Measured data is compared numerically to a mass attenuation data library storing mass attenuation data, individually or collectively, for a small number of expected constituent ingredients of the liquid to fit each intensity data item to the relationship given by the exponential attenuation law: I/I | 05-12-2011 |
20110116605 | Method and Apparatus for Inspection of Materials - A method of and apparatus for obtaining radiation transmission data and especially an image of an object in such manner that allows some data about relative proportions of constituent materials to be derived is described. A radiation source and a radiation detector system able to resolve transmitted intensity across a plurality of frequencies within the spectrum of the source are used to produce transmitted intensity data for each such frequency.

20110222658 | Detector Apparatus and Method - A detector apparatus is described for scanning of and obtaining radiation data from an object and generating an image therefrom. The apparatus comprises a radiation detector system spaced therefrom to define a scanning zone and to collect a dataset of information about radiation incident at the detector after interaction with an object and to resolve collected information spatially in two dimensions across a scan area and spectroscopically across a plurality of frequency bands in the spectrum of the source. A detector exhibits a spectroscopically variable response across at least a part of the spectrum of the source and to resolve collected information spatially with a rastering module configured to divide the scanning area into a plurality of pixels two dimensions; and a control to move the detector to scan such pixels successively and thereby collect a dataset for each pixel. A method is also described. | 09-15-2011 |
20110234378 | Tracking Device, System and Method - A tracking device for tracking with a radioactive material, a container including such a device, and a tracking method are described. The device has a radiation detector associatable with a radioactive material adapted to be placed in use within a container defining a radiation-shielded enclosure for containing a radioactive material, to detect radiation activity from the material. A RF identification module associatable with the container includes a data register to store a unique product identification code, a processor with a data transfer link to the radiation detector and data register to receive and process a live data stream of activity data from the detector and associate this with the unique product identification code in a processed data packet, and an antenna to enable transmission of a data item comprising both the unique product identification code and processed activity data to a remote data capture means. | 09-29-2011 |
20110260279 | Semiconductor Device Connection - A method of bonding a semiconductor structure to a substrate to effect both a mechanical bond and a selectively patterned conductive bond, comprising the steps of mechanically bonding a semiconductor structure to a substrate by means of a bonding layer; providing gaps in the bonding layer generally corresponding to a desired conductive bond pattern; providing vias though the substrate generally positioned at the gaps in the bonding layer; causing electrically conductive material to contact the semiconductor structure exposed through the vias. A device made in accordance with the method is also described. | 10-27-2011 |
20120116691 | Method for the Identification of Materials in a Container - Method for the identification of a homogeneous material (e.g. a liquid) in a container (e.g. a bottle) by measuring its X-ray or gamma spectrum and deriving its specific attenuation function. The method comprises building a database of the attenuation functions of empty containers, of containers filled with various fluid materials and of the contained fluid materials itself (by subtracting or devoluting the empty-container-attenuation-function from the filled-container-attenuation-function), recording the spectrum of an unknown material in a container and comparing this spectrum to the spectra in the database. | 05-10-2012 |
20130013242 | Cross Calibration of Two Energy Dispersive X-Ray Baggage Screening Systems Including Transformation of the Reference Database - A method of calibration of a dataset for spectroscopically resolved radiation scanning, comprising the steps of: generating an apparatus condition specific calibration dataset of emergent radiation intensity information generated after interaction in the scanning zone of at least one standard object spectroscopically resolved into a plurality of frequency bands; providing a transferable database comprising a dataset of transferable data items of emergent intensity information for a range of component materials, each spectroscopically resolved into a plurality of frequency bands and linked to the condition specific calibration dataset; defining a reference calibration dataset; generating a transfer function between the data item and the reference calibration dataset; applying the transfer function to the transferable data item to generate a dynamic data item adjusted to the reference calibration; populating a data register with a dynamic dataset comprising a dataset of data items each dynamically adjusted to the reference calibration. | 01-10-2013 |
