Abstract:
A communication module system, comprising:(a) a substantially coin-shaped module with an electrically conductive first flat face insulated from an electrically conductive second flat face plus abutting cylindrical surface with said second flat face extending beyond said cylindrical surface to form a flange on said module;(b) a printed circuit board disposed intermediate to said first flat face and said second flat face;(c) circuitry included with said printed circuit board, said circuitry with connections to said first and second flat faces, wherein said circuitry provides receipt of and transmission of digital signals as voltage differences between said first and second flat faces;(d) a power source disposed intermediate to said printed circuit board and said first flat face, said power source providing power to said circuitry; and(e) a first electrical contact electrically coupled to the first flat face and a second electrical contact electrically coupled to the second flat face, wherein said first and second electrical contacts are formable to match a variety of physical surfaces.
