Measuring and analyzing multi-dimensional sensory information for identification purposes
Methods and systems are provides for measuring multi-dimensional sensing information for identification purposes. The identity of one or more substances is determined through analysis of multidimensional data that can include, among others, intrinsic information as well as extrinsic information. The method for identification of a substance comprises utilizing pattern recognition to form descriptors to identify characteristics of the substance. A system and computer program for performing analysis of the multidimensional data are also described.

b) a code directed to acquiring over the computer network a second data from a second sensing device, wherein the second sensing device comprises at least one temperature, pressure or magnetic sensor that respectively detect temperature, pressure and magnetism of an environment in which the second sensing device is located;
c) a code directed to applying a pattern recognition algorithm to the first data and second data and performing a combined analysis on the first data and second data to classify or identify a substance; and
d) a code directed to performing filtering of the first data and the second data received over the computer network, wherein the filtering increases a signal-to-noise ratio of the first data and the second data prior to applying the pattern recognition algorithm to the first data and the second data.
