Abstract: An interactive computerized witness interrogation recording tool (10) which provides a way to rapidly convert verbal descriptions of objects and events into graphical displays. The verbal descriptions are entered into the interrogation recording tool (10) by an operator utilizing a keyboard (16), graphical input device (18) and an icon based control panel (32) in a display device (30). Commands utilized by the operator are stored in a command library (44) or originate from a textual algorithm (54) which can generate a time sequence of objects and events based on the statements. The representation of the object and events are stored in a 3D geometry database (46) which is displayed by using a geometry display generator (52) under control of a command interpreter (42) and on the display device (30). Because the display is created in real time, the individual providing the statements is able to immediately confirm or deny the accuracy of the representation as it is being constructed in its various stages.

Abstract: Human aesthetic evaluation of a finished painted surface, such as an automotive body, is automatically simulated by analyzing a distorted reflected test pattern from the finished surface. Fourier power spectra of the distorted test pattern are generated to form a parameterization of the reflected distorted test pattern. A correlation is statistically made to reference Fourier power spectra, each of which has been associated with a specific human aesthetic evaluation, such as wetness, dullness, softness, brightness, and the like. The Fourier power spectra of the distorted reflected image are automatically generated through a digitized two dimensional pixel map, which are mapped into functions of the edge direction and edge intensity of the pixels. The functions are then Fourier transformed into Fourier power spectra and correlated with reference reflected patterns.

Abstract: A flow path block having capability for storing a plurality of reactant volumes and for delivering the reactants through separate paths to a common mixing chamber where the reactants are mixed and delivered through reactant outlet means. Reactant outlet means may include a measurement chamber for determining the stopped flow kinetics of reactions in the mixture or may be a path for delivery of the mixed reactants to an external vessel for some subsequent intended use.
