20140099729 | Methods and Apparatus for Artificial Olfaction - In exemplary implementations of this invention, an electronic olfactor determines whether a scent being tested matches the scent of a positive control. The electronic olfactor can perform this scent matching even in a changing olfactory environment, and even if the positive control scent is a combination of hundreds or thousands of different odorants. No prior training is needed, and no attempt is made to identify a single odorant that is unambiguously responsible for a scent. Instead, a computer compares the total scent pattern of a positive control sample with the total scent pattern of a test sample, across a sweep of many permutations of electrical inputs to scent sensors, to try to find any condition under which the total scent patterns do not match. If such a condition cannot be found, then the computer declares a match between the test and target scents. | 04-10-2014 |
