Abstract: A textile form touch sensor comprises first and second outer conductive layers, and a third layer, intermediate of the first and second layers. The third layer comprises a non-conductive textile coated with a piezoresistive material. In a preferred embodiment, the piezoresistive material is coated on the nonconductive third layer so as to form an arrangement of defined blocks of piezoresistive material, and the first, second and third layers are joined together in a series of straight lines, the lines running in between the defined blocks of piezoresistive material.

Abstract: A filament or fibre (2) comprising: a first conductive layer (4); an electro-optically active layer (6); a second conductive layer (8); wherein the filament or fibre has an off-state and an on-state, the electro-optically active layer comprising a combination of an electro-optically active substance and a polymer.

Abstract: The invention relates to an optical scanning device for scanning an information carrier comprising a plurality of information layers which optical properties depend on a potential difference applied between two electrodes. The optical scanning device comprises a fixed part comprising means (302) for generating a signal comprising information about a selected information layer, and a rotating part comprising means (301) for receiving the information carrier. The receiving means comprise a plurality of contacts (311-318) for connecting the electrodes, means (303) for detecting the signal, means (304) for decoding the signal and means (304) for applying a potential difference between the contacts connected to the electrodes corresponding to the selected information layer.

Abstract: The invention relates to an information carrier comprising at least two information stacks. Each stack comprises a first electrode (11, 15), a second electrode (13, 17) and an information layer (12, 16) between the first and second electrodes. The information layer comprises molecules which can be rotated when a suitable potential difference is applied between the first and second electrodes.

Abstract: An optical record carrier (2) and associated methods and devices are described. The carrier (2) comprises at least one user information layer (4a,4b) arranged to be scanned by first radiation, and at least one content information layer (3a,3b) or label layer.

Abstract: Optical data storage method, reading method, device (40) and storage medium (42,43), comprising storing data by modifying optical properties of polymer material (42), whereby writing is initiated by reorientation of photo-orientable units, typically by illuminating with light at a wavelength that initiates the reorientation, and whereby reading of data includes collection of anisotropic emission from dipole emitters.

Abstract: The present invention relates to a multi-stack optical information carrier for recording information by means of an optical beam, said optical information carrier comprising—a substrate layer (S),—at least two recording stacks each comprising a recording layer (P1-P7),—at least one spacer layer (R) separating the at least two recording stacks, and—a cover layer (C). In order to improve the sensitivity during writing it is proposed according to the present invention that the recording layers (P1-P7) include a thermochromic material having temperature-dependent optical characteristics for selectively improving the sensitivity of the addressed recording layer (P1-P7) during recording and/or read-out.
