摘要:
A fully automated package identification and measuring system, in which an omni-directional holographic scanning tunnel is used to read bar codes on packages entering the tunnel, while a package dimensioning subsystem is used to capture information about the package prior to entry into the tunnel. Mathematical models are created on a real-time basis for the geometry of the package and the position of the laser scanning beam used to read the bar code symbol thereon. The mathematical models are analyzed to determine if collected and queued package identification data is spatially and/or temporally correlated with package measurement data using vector-based ray-tracing methods, homogeneous transformations, and object-oriented decision logic so as to enable simultaneous tracking of multiple packages being transported through the scanning tunnel.
摘要:
A process for coating the surface of pigment and filler particles with an oleaginous and cosmetically functional material, characterized in that an aqueous suspension of the pigment or filler is mixed with an emulsion of said oleaginous material to be coated onto the surface of pigment or filler particles, followed by adding a component capable of breaking the emulsion to the thus obtained mixture, whereby the emulsified material coalesces onto the surface of the pigment or filler particles. The thus obtained pigments or fillers exhibit excellent properties when used in cosmetics.
摘要:
A device for use in a test procedure in which a plurality of discrete fluid samples is disposed on a microscope slide which comprises a slide support and clamping means for clamping a slide between a gasket provided with a plurality of apertures therethrough and said support, said clamping means being adapted, when actuated, to apply pressure to the gasket whereby said apertures are sealed against said slide in a fluid tight manner to provide a plurality of wells for introduction of fluid thereto.
