Abstract: A multicontact transparent tactile sensor including two at least partially conducting transparent layers, the layers being spaced apart by an insulating transparent material. At least one of the layers includes a transparent sheet on which is deposited an array of conducting tracks whose width is less than 80 microns.

Abstract: An electronic analysis circuit for a passive-matrix multicontact tactile sensor including an electrical supply mechanism feeding one of two axes of the matrix, and a mechanism for detecting electrical characteristics along the other axis of the matrix, at intersections between the two axes. The electrical characteristic measured is alternately capacitance and resistance. A multicontact passive-matrix tactile sensor includes an electrical supply mechanism feeding one of the two axes of the matrix, a mechanism detecting electrical characteristics along the other axis of the matrix, at the intersections between the two axes, and such an electronic analysis circuit.

Abstract: The disclosure relates to a transparent multi-tactile sensor including a transparent semi-conducting active layer provided between two transparent conducting layers arranged as an array of cells formed by the intersection of rows and columns, characterised in that it comprises a control circuit successively supplying each semi-conducting portion corresponding to a cell, said control circuit including a means for analyzing the variation in the electrical characteristics due to the deformation of one or more sensor areas, each area including one or more cells, the semi-conducting characteristic of said intermediate layer making said cells independent from the measuring circuit.

Abstract: The present invention relates to a multipoint touch sensor with active matrix comprising: —a matrix layer exhibiting N×M independent cells, each of the cells Px, y being linked to a row Lx and to a column Cy through a switching element, the rows Lx being common to all the cells Px, i, i lying between 1 and N, and the columns Cy being common to all the cells Pj, y, j lying between 1 and Q, Q being at most equal to M, an intermediate layer able to cause a local modification of the electrical properties of the cells situated under the tactile activation zone, said intermediate layer being placed between the active surface of the adjacent surface of the said Px, y, cells, —an upper activation layer allowing tactile interaction, —an electronic circuit sequentially controlling, for each set of cells Ca, b1-b2 with b2-b1 lying between 1 and Q, a first step of activating said cells Ca, b1-b2 followed by a second step of detecting the electrical properties of each cell Ca, b1-b2 individually so as to deliver an item o

Abstract: A process for controlling computerized equipment with a device including a multi-contact bidimensional sensor that acquires tactile information and a calculator that generates command signals as a function of the tactile information, including graphical objects on a screen placed under a transparent multi-contact tactile sensor, each graphical object associated with at least one specific processing rule such that the sensor delivers during each acquisition phase a plurality of tactile information, and each piece of the tactile information forms an object of a specific processing determined by its localization relative to a position of one of the graphical objects.
