Abstract:
An electro-optical system capable of being embarked aboard mobile ground or flying units, to determine the optical flow generated by obstacles in relative motion with respect to the mobile unit. The system comprises radiation (5), receiver means (1) for converting the radiation reflected by the objects into electrical signals and means (8) for processing the signals generated by the receiver means. The receiver means (1) are based on vision sensors with matrix configuration. The emitter means (5, 6) shape the radiation beam in such a way that the radiation reflected by the objects and collected by the receiver means impacts at least on a part of the receiver matrix. The processing means compute the optical flow only on the elements of the receiver matrix that are impacted by the radiation.
Abstract:
A system for the production of electrical energy, comprising: a combustion chamber (14) made of material that is able to withstand high temperatures, an injection device (16) connected to said combustion chamber (14) by means of an injection conduit (15), means (17) for supplying combustion support substance into the combustion chamber (14) and means (18) for the removal of gaseous combustion products, means (26) for the selective emission of radiation onto the outer surface of the combustion chamber (14). The combustion chamber (14) is enclosed in a conversion chamber (20) within which are maintained sub-atmospheric pressure conditions, so that a substantial part of the heat developed by the combustion reaction is converted into electromagnetic radiation.
Abstract:
Una porción sustancial de los bordes periféricos de dos paneles (20a, 20b) que forman un componente (20) de una carrocería de vehículo de motor, en particular la capota frontal de un vehículo de motor, se une al interponer un adhesivo termoendurecible. La polimerización del adhesivo se obtiene por calentamiento, sin introducir la estructura en un horno, por medio de una o más bobinas (33) de calentamiento por inducción, las cuales están conformadas y distribuidas en proximidad y a lo largo de los bordes periféricos de los dos paneles (20a, 20b). La calidad del procedimiento de calentamiento por inducción se controla de acuerdo con las señales transmitidas por una cámara (V) de detección termográfica la cual se coloca ajustable en un punto desde el cual puede adquirir una imagen termográfica de toda la extensión de los bordes periféricos de los paneles que se van a unir de manera que permite control simultáneo de la temperatura alcanzada por cada porción de los bordes periféricos de los paneles (20a, 20b).
Abstract:
A user-interface device comprises a plurality of indication elements (3), each provided with a visual indication (4), mounted on a structure (5). The indication elements (3) comprise identification means (9b, 10, 11, 11') adapted for co-operating with detection means (6, 7) of the device (1), for unique identification the indication elements (3). The identification means (9b, 10, 11, 11') comprise an electrically conductive layer (10) on a respective side face (6b) of the indication element (3) and an electrically insulating layer (9b) superimposed on the electrically conductive layer. The detection means (6, 7) comprise one or more contact elements (7) set up against a respective a side face (6b) of the indication element (3). The electrically insulating layer (9b) has one or more windows (11) for exposure of respective local portions of the underlying electrically conductive layer (10), each window (11) being made in a position substantially corresponding to a respective contact element (7).
Abstract:
A luminous display for automotive satellite navigation systems comprises a panel (10) equipped with light sources, for example made up of LEDs, arranged in a pre-ordered configuration of discrete segments (1, 2, 3, 4, 6, 7, 8), which can be combined with one another according to paths corresponding to the representation of a plurality of encoded generally arrow-shaped pictograms (P1-P4), each of which indicates a respective direction to follow indicated by the navigation system. The path to follow is highlighted with respect to possible alternative paths represented by the pictograms.
