摘要:
A method and system for improving the accuracy of digital ink (310) searches is disclosed. The method includes receiving a search input query (370) from a user via a user terminal and determining a specialized format of digital ink, by a variety of means, then, based on the determined specialized format of digital ink, a digital ink searching algorithm is selected. A search (380) of a digital ink database (350) can then be performed for a match to the search input query (370) by utilising the digital ink searching algorithm, which is selected from a variety of algorithms so as to improve the accuracy of the search.
摘要:
The present invention provides an IR-absorbing naphthalocyanine dye of formula (I): wherein M is selected from Ga(A1); A1 is an axial ligand selected from OH, halogen (preferably Cl), OR3, a hydrophilic ligand and/or a ligand suitable for reducing cofacial interactions; R1 and R2 may be the same or different and are selected from hydrogen or C1-12 alkoxy (preferably C1-6 alkoxy); R3 is selected from C1-12 alkyl, C5-12 aryl, C5-12 arylalkyl or Si(Rx)(Ry)(Rz); and Rx, Ry and Rz may be the same or different and are selected from C1-12 alkyl, C5-12 aryl, C5-12 arylalkyl, C1-12 alkoxy, C5-12 aryloxy or C5-12 arylalkoxy; W is a hydrophilic group; n1 is 0, 1, 2 or 3; n2 is 0, 1, 2 or 3; n3 is 0, 1, 2 or 3; n4 is 0, 1, 2 or 3; provided that at least one of n1, n2, n3 or n4 is greater than 0. Dyes of this type are especially suitable for use in netpage and HyperlabelTM systems.
