Abstract: A fully automated, high output robotic station for the crystallization of proteins and other biopolymers via the sitting drop vapor diffusion and micro-batch methods. This station performs microplate feeding, liquid aspiration, dilution, and dispensing, as well as microplate sealing and storage into a temperature controlled hotel. All functions are microprocessor controlled. The operator designs the process via graphical user interface, after which the station executes the process automatically to completion.

Abstract: There is disclosed a system for visually measuring the cross-sectional thickness of a light-reflective object, such as a vehicle wheel, said object having a plurality of curved surfaces. The system includes: means for transmitting a line of light onto each curved surface of the object at substantially the same cross-sectional area through the object; means for sensing the lines of light reflected from each curved surface and producing a plurality of signals thereby, said signals representing a linear profile of each curved surface at the same cross-sectional area; and means for comparing the profile signals from each curved surface for calculating a cross-sectional thickness of the object at one or more points along the same cross-sectional area. On a more preferred basis, this system further includes means for supporting the object, and means for rotating the object about at least one axis of support to measure a plurality of cross-sectional thicknesses thereof.
