A micro-computer system for cell electrophoresis measurements

Experimental measurements of the velocity of blood cells have been used in research into the early detection of cancer in patients. These measurements have been made by manually timing cells moving across a television screen. This technique is tedious, involves the timing of over a hundred cells and is therefore subject to error. A low-cost microcomputer system was designed to automate the measurement of cell velocity in order to give faster and more accurate results.
