  • Patent number: 4827084
    Abstract: A solid state, touch sensitive position sensor, which sensor includes a conductive surface along the boundaries of which are disposed at least two sets of two elongated current distribution and collection means. The touch sensitive position sensor further includes resistance means operatively disposed so as to interconnect said current distribution and collection means with said conductive surface. The current distribution and collection means and resistance means are configured, so as to (1) provide a substantially linear electric field distribution of equipotential lines and (2) sequentially turn one set of said current distribution and collection means on while turning the other sets off. In an important embodiment, the conductive surface is formed immediately atop a copyboard and by utilizing erasable, felt tip markers having metallic inserts therein, visual images as well as electrical signals, indicative of X-Y coordinate location, may be simultaneously generated.
