Abstract: The invention relates to a device (FIG. 14) making it possible to generate a group of light beams with statically or dynamically controlled pointing adjustment, e.g. with the aid of an optical matrix head feeding the last stage of an item of multibeam digital projection video equipment, comprising a certain number of rotary optical disks. The device comprises a certain number of elements/devices for static adjustments, e.g. of screw plus spring type, or dynamic adjustments, e.g. of micro jack and/or piezo-electric type, carrying out dynamic trim control with the aid of a device, e.g. of pyramidal, conical or other shape, within an optical matrix head. A digital control providing feedback control for the position and lighting of the sources thus makes it possible to create a succession of coloured pixels at the output of the device. According to the desired configurations, several sources may be associated, e.g. within an optical matrix head, to create a matrix of coloured pixels.

Abstract: Engine for video projection/digitiser/digital radar with multiple electromagnetic radiation beams for carrying out the projection or recording in 2D or 3D on any surface or in any volume. The invention relates to an optical digital video projection device for multi beam projection onto any surface or into any volume in 2D or 3D, within a solid angle from 0° to 360°, for example, 180, 270, or 360°. The device can also be used in digitiser and/or radar function for the recording/digitisation of spatial and frequency information. The processing of electromagnetic radiation, for example, visible, infrared ultraviolet, microwave radiation in lime, space and frequency either passively or actively for example, by means of mirror/filter windows permits a filter function specific to the target applications. The source uses a light source comprising, for example, a number of weak/medium/high power lasers coupled to a number of optical sources, optical source modules, coloured beam generators or optical matrix heads.

Abstract: The invention comprises a method to increase the water absorption of tissue paper towel products by incorporating super-absorbent polymers (SAP) in between the laminated tissue plies. The SAP is dosed in selected places in the tissue towel manufacturing process without the need to substantially change the current converting or manufacturing process, or the major equipment that is used or the properties of the base sheet tissue paper.
