Abstract:
A touch sensitive navigational surface functions as a user interface to a communication device such as a cellular telephone. An electromechanical dielectric (EMD) film coextensive with at least a portion of the surface of the cover of the device selectively functions as a sensor, microphone or speaker. The EMD film is placed behind a display to provide a user interface touch sensitive screen capable of sensing the direction of touching. At least a portion of the EMD film functions as a fingerprint recognition system to provide security means for controlling access and limiting call completion to an authorized user.
Abstract:
The present invention concerns a dielectric film for converting the energy of an electric field or of a magnetic field into mechanical work, orfor converting mechanical work into electric energy, and a procedure for manufacturing the film. The film of the invention consists of a homogeneous, e.g. a film layer (A) foamed to a structure (C) of full-cell type and which has been oriented by stretching it in two dimensions and coated at least in part on one side or on both sides with an electrically conductive layer (B). The film is manufactured by extruding the plastic which has been made to be foams able, into tubular shape, performing intermediate cooling of the tube and reheating it, expanding the heated tube in two dimensions, metallizing the outer surfaces and cutting the tube open to become a film.
Abstract:
A touch panel is provided to realize excellent the durability of a conductive thin film by using a panel forming the conductive thin film on a film substrate as an upper/lower substrate. A first conductive panel(A) has a first transparent film(1) and a first transparent conductive thin film(2) formed on one side of the first transparent film. A second conductive panel(B) has a second transparent film(101) and a second transparent conductive thin film(102) formed on one side of the second transparent film. The first panel and the second panel are faced with each other by interposing a spacer(s) between the first and second conductive thin film. The hardness and elasticity of surface of the second conductive thin film are smaller than the first conductive thin film.

Abstract:
PROBLEM TO BE SOLVED: To provide a method and related devices for a sensor system, using an electromechanical dielectric (EMD) film having a spread similar to at least a part of the surface of communications equipment. SOLUTION: The method for arranging the sensor system in the communications equipment has a step of disposing the electromechanical dielectric film integrated with the cover surface of communication equipment, a step which arranges one or a plurality of idle regions in an outer region in a cover for accessing the electromechanical dielectric film and which corresponds to an operational function where the idle region is to be performed, and a step connecting the electromechanical dielectric film to the electronic circuit means, associated with the corresponding operating functions of communications equipment in the exposed region.
