81 Electronic pressure sensitive transducer apparatus and method for manufacturing same US10067952 2002-02-05 US06909354B2 2005-06-21 Jeffrey R. Baker; Carlos S. Sanchez
The cost and complexity of an electronic pressure sensitive transducer are decreased by constructing such a transducer directly on a printed circuit board containing support electronics. Conductive traces are formed on the printed circuit board to define a contact area. A flexible substrate having an inner surface is positioned over the contact area. An adhesive spacer, substantially surrounding the contact area, attaches the flexible substrate to the printed circuit board. At least one resistive layer is deposited on the flexible substrate inner surface. In use, the resistive layer contacts at least two conductive traces in response to pressure applied to the flexible substrate to produce an electrical signal indicative of applied pressure.

91 Flexible touchpad circuit with mounted circuit board US999908 1997-12-19 US6002594A 1999-12-14 Marc Ledin; Bernard Kasser; Stephen J. Bisset
An improved flexible substrate for a touchpad, with the flexible substrate having conductive ink for forming a sensor array. A printed circuit board is also used, but only for the components which need to connect to the array, and not the array, thus giving a smaller printed circuit board. The printed circuit board can have the components compactly mounted on it taking advantage of the close spacing available in PC board technology. The PC board itself has wider spacing on its contacts at its outer edges, allowing it to be attached by conductive glue to the flexible substrate.

98 Sheet membrane keyboard and electronic apparatus using same US784720 1985-10-07 US4736190A 1988-04-05 Charles M. Fiorella
The present invention is a simplified membrane keyboard employing a single flexible sheet. This membrane keyboard is employed in an electronic apparatus having an external case with a nonconducting keyboard surface. This nonconducting keyboard surface has a plurality of depressions corresponding to key switch positions. The keyboard surface is covered by a keyboard sheet. This keyboard sheet has a flexible membrane with opposed first and second surfaces, the first surface disposed adjacent to and substantially covering the keyboard surface of the external case. An interconnection pattern is placed upon the first surface of the flexible membrane. This interconnection pattern has a plurality of conductors and most particularly has a pair of conductors in proximity at each key switch position. Pressure applied to the second surface of the flexible membrane causes the flexible membrane to flex until the two conductors contact a conductive layer disposed in the bottom of the corresponding depression. This contact causes electrical conduction between the two conductors, thereby giving rise to a closed key operation. In a preferred embodiment graphic matter identifying the key areas of the flexible sheet, that is those areas overlying the depressions, is applied to the second surface of the flexible sheet. This invention is adapted for use in calculators, electronic learning aids, electronic games, small computer systems and other electronic apparatuses which employ keyboards.
