| 91 | Robotic skin | US853637 | 1986-04-18 | US4694231A | 1987-09-15 | Joseph G. Alvite' |
| A multi-layered tactile sensing skin is provided for a robotic arm or the like. The skin includes adjacent layers of electrically insulative film having opposed contiguous surfaces. An electrically conductive carbon based compound is applied uniformly to one of the surfaces, while the other surface is selectively coated with silver oxide to form a series of pairs of first and second electrically conductive regions separated from one another by a dielectric gap. The carbon based conductor bridges the gap betwen the conductive regions in each pair, permitting flow of electrical current between the regions. The current flow increases with an increase in pressure over the interface between the layers of film, and the amperage increase can be utilized to trigger a signal to the robot power supply, to decelerate, stop or reverse arm movement. | ||||||

| 96 | Membrane switch having adhesive label as edge seal | US159954 | 1980-06-16 | US4375018A | 1983-02-22 | Stephen K. Petersen |
| A membrane switch comprised of first and second flexible layers having corresponding patterns of metallization thereon, these layers being separated by an apertured spacer. The first layer is of a larger size than the spacer and the second layer is of a smaller size than the spacer so that when the three are superposed, a border on the first layer and spacer are exposed to meet the second layer. Completing the assembly is a label layer which is of a flexible, non-conductive material having a desired pattern of graphics printed on it and an adhesive coated undersurface. When the label layer is pressed against the exposed surface of the second substrate, it bonds all three of the lower layers together and creates a seal around the perimeter of the switch assembly. With the label layer being of a greater size than the other three layers, it may also be used to affix the composite switch to the appliance on which it would be used. | ||||||
