Abstract: An improved method for detecting truth or deceit (15) comprising providing a video camera (18) adapted to record images of a subject's (16) face, recording images of the subject's face, providing a mathematical model (62) of a face defined by a set of facial feature locations and textures, providing a mathematical model of facial behaviors (78, 82, 98, 104) that correlate to truth or deceit, comparing (64) the facial feature locations to the image (29) to provide a set of matched facial feature locations (70), comparing (77, 90, 94, 100) the mathematical model of facial behaviors to the matched facial feature locations, and providing a deceit indication as a function of the comparison (78, 91, 95, 101 or 23).

Abstract: A test cell apparatus and method for measuring gases emitted from a test ple. The apparatus having hollow, enclosed, gas impermeable chamber having side walls terminating at a closed end and a gas transfer end. The gas transfer end receives and emits a flow of a gas therethrough. The cell has a planar platform in the chamber extending from the closed end to the gas transfer end defining a first chamber portion including a first gas transfer end portion, and a second chamber portion including a second gas transfer end portion. The platform has an opening therethrough at a location proximate to the closed end of the chamber and a fan installed in it near the gas transfer end. Means are provided for fixing a test article through the platform such that part of the test article is positioned and exposed within the first chamber portion and another part of the test article is positioned and exposed within the second chamber portion.
