Patent EP-0443187-A2 (EP)
Inventor: WIESMEIER CHRISTIAN
IPC: H04B7/26
Filed: 1990-12-21
Abstract: The use of a wireless data transmission system to or from a motor vehicle can be degraded due to constantly increasing data traffic. There is therefore a need for a data transmission system which is at least group-selective. It is therefore proposed according to the invention to assign given transmission channels to predefined geographical motor vehicle travelling directions. On the motor vehicle side, a transmission channel can be selected automatically according to the direction of movement of the motor vehicle. Both assigned transmission channels can be used in the transitional area between adjacent geographical travelling directions. Advantageously, the only information which needs to be transmitted on one transmission channel is, for example, the information which is relevant to a sub-set of system participants for a specific geographical travelling direction. When dialogue takes place between system participants, two-way decoupling is achieved. The field of application is wireless communication with or between motor vehicles, e.g. for the transmission of traffic information.

Abstract: An autostereoscopic viewing device with a flat picture screen and a pattern of cylindrical lens portions for producing three dimensional image perceptions without the need for additional optical accessories. The viewing device provides the largest possible freedom of movement of the viewer, whereby the reproduction quality is as uniform as possible and out of focus, cross-talk and other disadvantageous optical effect are greatly reduced. The procedures for making any necessary optical corrections are based on the plane parallel changeable positioning of a flat picture screen relative to an array of cylindrical lens portions. The array of cylindrical lens portions has an increasing thickness as well as a decreasing pitch width when moving from the middle to the vertical side edges. The pixel, or picture strip, size on the picture screen is a constant.

Abstract: In a speech recognition system where a speech analyzer (12) analyzes an input utterance to produce an input speech pattern which is memorized in an input memory (14) as a memorized input pattern, a pattern comparator (16) comparing the memorized input pattern with reference patterns previously memorized in a reference pattern memory (15) and producing pattern dissimilarities between them, and a speech deciding circuit (18) deciding the minimum pattern dissimilarity to thereby recognize the input utterance, a word is uttered twice during a registration mode in order to correctly register the speech pattern of the word the reference pattern memory (15). Speech patterns of the first and the second utterances of the word are memorized in the reference pattern memory (15) and the input memory (14) as first and second memorized patterns, respectively, which are compared with each other at the pattern comparator (16) to produce a pattern dissimilarity. A registration deciding circuit (19) is selectively coupled to the pattern comparator (16) during the registration mode and decides whether or not the pattern dissimilarity is larger than a predetermined reject value and permits one of the first and the second memorized patterns to be registered as a reference pattern into the reference pattern memory (15) when the pattern dissimilarity is not larger than the reject value.

Abstract: Infra-red filter discs for radiation detectors, in particular for passive infra-red detectors, have improved opacity to interfering light if they comprise an infra-red radiation-transparent plastic which contains zinc sulphide particles having a particle size in the range from 0.5 to 50  mu m, preferably in a concentration of about 13 per cent by weight, uniformly distributed therein. The scattering effect of the pigment particles is further improved if the surface of the infra-red diffuser discs has a surface roughness of about 1  mu m. This causes additional scattering of light having a wavelength of < 2  mu m, but allows light having a wavelength of from 4 to 15  mu m to pass unhindered. Before mixing, the zinc sulphide should be screened so that a particle size in the desired range is obtained.

Abstract: An overlapping image area is produced on the border between adjacent image areas by processing of image data so as to eliminate a dropout due to registering mismatch. A target image area CR2, specified by an operator, is expanded by a predetermined width  d  to produce overlapping image areas CR4 and CR5. The color of the overlapping image area CR4 or CR5 is determined based on the color of the target area CR2 and the original color of the overlapping image area CR4 or CR5. For example, the larger value between each color component of the original color of the overlapping image area and that of the color of the target area is selected as the new color component of the overlapping image area.

Abstract: A multiple wavelength semiconductor laser (10) has two active layers (16, 20) separated by either a p-cladding layer (18) or p-n junction cladding layers (46, 48). A p-disordered region (28) and a n-disordered region (26) extend through one of the active layers and into the intermediate cladding layer. A lateral waveguide (56) is formed between the disordered regions in the active layer, and a deep waveguide (54) is formed beneath the p-disordered region in the other active layer. Since both active layers generate lightwaves at different wavelengths, forward-biasing the p-disordered region can cause either or both waveguides to emit radiation but at different wavelengths. The deep waveguide can also be buried heterostructure laser.

Abstract: A cylindrical multi-port combiner (10) has a graceful degradation characteristic with a high degree of isolation (25 db) between ports (12) and a high combining efficiency (>90°). Radially-spaced inner and outer conductors (20, 21) forms a transmission line (19) operating in a balanced mode. Circumferentially spaced plurality of like transmission lines (19) have inner and outer RF absorbers (46, 47) at the outermost regions of the spaced adjacent inner and outer conductors (20, 21), respectively. A corresponding end of each transmission line (19) is adapted to be connected to one of a corresponding number of phase-matched RF sources at the input ports (12). The other end of each transmission line (19) has its inner and outer conductors (20, 21) connected in parallel, respectively, through stepped impedance-transforming transmission lines (77) to form one connector (13, 78) for connection to an output RF load. The RF field of the desired balanced mode does not extend beyond adjacent inner and outer conductors (20, 21) to the absorbers (46, 47); whereas when a failure of a source occurs, the resulting unbalanced mode will have its field extend to the absorbers (46, 47) to be damped without significantly affecting the output from the remaining operative sources.

Abstract: The invention relates to a roller shutter with a large number of laterally guided roller shutter profiles which are articulated on one another. On their rear side, these roller shutter profiles have groove-shaped recesses, in which the teeth of toothed wheels, arranged on a guide tube, engage as drive means. The guide tube is surrounded by a torsion spring which is fastened on the one hand to the central stationary shaft, which passes through the guide tube, and on the other hand to the guide tube itself. The guide tube is furthermore closed on both sides by end caps which support the shaft and are inserted into its opening. The characteristic feature of the invention is seen in that the end caps (5), which are inserted into the opening of the guide tube (3) on the end sides, project out of the opening with part regions (51). From these part regions (51), there project beyond the outer circumference of the guide tube (3) tooth-like projections (511) which are distributed uniformly on the circumference. These projections (511) engage in corresponding receiving grooves (421) which extend over the axial length of the toothed wheels (4) and are arranged on the inner circumference of the central bore (42) of the toothed wheels (4). The end caps (5) are at the same time mounted rotatably movably on the shaft (6). The toothed wheels (4) are detachably connected to one another with the end caps (5) via the guide tube (3), in each case by means of mechanical fastening means (41) which reach through.
