Abstract: A method of calibrating a dispenser, which has a material dispensing unit that is configured to dispense material on a substrate, includes dispensing a line of material on a surface, capturing at least one image of the line dispensed on the surface, calculating an average line width of the line dispensed on the surface, and comparing the average line width of the line dispensed on the surface to a desired line width. A controller configured to perform the method is further disclosed.

Abstract: An improved touch-panel and method of increasing the percentage of useful area of a touch-sensitive panel include electrode elements in electrical communication with an electrically conductive layer of known spatial impedance characteristics. The touch-panel structure incorporates improved electrode structure and electrode to impedance layer interfacing elements which impart a more linear mapping function within an expanded touch-sensitive region of the resistive layer. The touch-panel can be utilized in a general touch-mapping system without resort to extensive mapping coordinate correction apparatus of earlier systems.
