20130054148 | INTERPRETATION - An improved method of comparing a first data set with a second data set is provided, particularly suited for data sets arising from the analysis of DNA samples, in which both first and second data set are compared with one another, the comparison occurring before any processing of the data has occurred. In this way an empirical analysis of the data is provided which does not introduce any of the errors or data omissions inherent in an interpretive approach to data analysis. | 02-28-2013 |
20120087554 | METHODS FOR COMPARING A FIRST MARKER, SUCH AS FINGERPRINT, WITH A SECOND MARKER OF THE SAME TYPE TO ESTABLISH A MATCH BETWEEN THER FIRST MARKER AND SECOND MARKER - A method of comparing a first representation of an identifier with a second representation of an identifier, for instance two fingerprints is provided. The method includes selecting a plurality of features in the first representation of an identifier, such as minutia, and linking each feature to one or more of the other features. The information on the features, such as is the minutia type, and on the link or links, such as distance, can then be expressed as a vector. By comparing the vector for the first representation with a vector for the second representation information on the possibilities for them having a common source can be obtained. | 04-12-2012 |
20110255793 | IDENTIFIER INVESTIGATION - A method of extracting data from a representation of an identifier, such as a fingerprint is provided. The method includes selecting a plurality of features, such as ridge ends or bifurcations, in the representation of an identifier, considering the positions of those features and generating a reference feature, such a s a centre, from the positions of the plurality of features. The method then links one or more of the features to the reference feature and/or links one or more of the features to one or more of the other features in the plurality of features. From the result, the method extracts data including information on one or more of: one or more of the plurality of features; the reference feature; one or more of the links between a feature and the reference feature; one or more of the links between a feature and another feature. | 10-20-2011 |
20090170106 | ANALYSIS OF DNA - The invention provides improved techniques for investigating DNA samples, which offers improved sensitivity and specifity. | 07-02-2009 |
20090117579 | Relating To The Handling Of DNA - A variety of methods are provided which use a silicon or silicon dioxide channel to extract DNA from a sample and then release it at a later point. The extraction channels are simple to manufacture and reliable in use. Prior art problems with entrainment of gas, liquid and solid material within channels are addressed. The techniques provide a convenient way of controlling the amount or concentration of DNA in the eluant. | 05-07-2009 |
20090023154 | RELATING TO MARKING - The invention provides a marking system, markers and methods of use of such marking systems and markers which enable unique marking of articles and subsequent detection of that marking. In particular the invention provides a marking system, the marking system comprising a plurality of different DNA fragment types, each of the plurality of different DNA fragment types comprising a plurality of different length DNA fragments and a method in which a sample of the DNA fragment type is taken, amplified and analysed to determine the identity of the marker for an article. | 01-22-2009 |
