Abstract: Un microscope à balayage laser (10) provoque l'excitation moléculaire d'un matériau cible par absorption simultanée de deux photons entraînant ainsi une résolution tridimensionnelle intrinsèque. Des fluorogènes présentant une absorption de photons unique dans les longueurs d'ondes courtes (ultraviolet ou visible) sont excités par un flux d'impulsions (14), inférieures à la picoseconde et fortement focalisées, de lumière laser d'étendue de longueur d'onde relativement longue (rouge ou infrarouge). Les fluorogènes absorbent à au moins une demie longueur d'onde laser de manière à produire des images fluorescentes de cellules vivantes et d'autres objets microscopiques. L'émission fluorescente provenant des fluorogènes augmente de façon quadratique avec l'intensité d'excitation de telle sorte qu'en focalisant fortement la lumière laser (14), la fluorescence aussi bien que le photoblanchissement sont limités au niveau du plan focal (18). Cette caractéristique fournit une profondeur de résolution de champ comparable à celle produite par des microscopes à balayage laser à foyer commun, et de plus réduit le photoblanchissement. Le balayage du faisceau laser (14), par un microscope à balayage laser (10), permet une construction d'images par réception de fluorescence causée par deux photons à partir de chaque point dans l'objet balayé tout en satisfaisant l'exigence d'une intensité d'excitation très élevée obtenue par la focalisation du faisceau laser (14) et par la compression d'impulsions du faisceau. Les impulsions focalisées assurent également une photochimie à résolution spatiale tridimensionnelle qui est particulièrement utile dans la libération photolytique de molécules effectrices en cage.

Abstract: Self-supporting structures of diverse shapes are disclosed that may be collapsed down to a compact bundle. In them, units are employed that are comprised of a central tapered strip bordered by two elongated strips. The tapered strip is pleated along a series of lines that cross it widthwise and each elongated strip is pleated along a series of lines that cross it widthwise. The central tapered strip is joined to each of the two elongated strips by a series of pleat lines that are connected end-to-end. When the unit is folded, each of the two elongated strips fold into a stack, and the central tapered strip folds in a zig-zag fashion, such that the planets of the tapered strip lie essentially orthogonal to the planes of the stacked elongated strips. The two stacked elongated strips fold towards each other, such that the stacks lie in line with one another.

Abstract: A series of images of a full motion video scene is divided into a number of sub-series which, when interleaved, represent the original series. A ranking order increasing magnitude is allocated to consecutive sub-series. Each image of a sub-series is converted into an image data block, while images from one or more sub-series having a lower order of precedence are considered for this conversion. A packet header indicating the ranking order of the sub-series with which the corresponding image is associated is added to each image data block. 
     The display apparatus is adapted to select those image data blocks which have predetermined packet headers and to subject the image data blocks thus selected to a decoding process. The number of different packet headers which is selected determines the temporal resolution of the scene to be displayed.
