Abstract:
A technique for detecting spills is disclosed. A number of electrodes within a portion of a surface are connected to a resistance meter. The resistance meter detects a spill by measuring a change in resistance between two or more electrodes when a fluid is spilled over the two or more of the electrodes. The location of the spill can also be determined based on a known location for each of the electrodes. The size of the spill can further be determined based on a number of electrodes which measured a change in resistance due to the spilled fluid.
