Abstract: Bei bekannten Systemen müssen im Differenzpulscodemodulator an einer Stelle in einer zeitkritischen Schleife eine Anzahl Verarbeitungsschritte innerhalb eines Abtasttaktes durchgeführt werden, nämlich eine Summenbildung, eine Multiplikation mit Addition, eine Differenzbildung und eine Quantisierung. Für den insbesondere bei der Bildverarbeitung fast immer auftretenden Fall, daß zwischen den für den Vorhersagewert verwendeten Signalen eine Anzahl Signale liegt, die nicht für den Vorhersagewert verwendet werden, wird eine Lösung angegeben, bei der innerhalb der zeitkritischen Schleife nur eine Zuordnung und eine Addition erforderlich ist. Eine solche Anordnung entspricht einer speziellen Aufteilung der Gleichung für das Vorhersagefehlersignal in einzelne Terme. Die angegebene Lösung läßt sich in verschiedener Weise zur Einsparung von Aufwand abwandeln und auch für adaptive Modulatoren verwenden. Die gleichen Maßnahmen können auch im Demodulator verwendet werden.

Title: Data compression
Inventor: CRAYSON PAUL
IPC: G06T9/00
Filed: 1987-04-30
Abstract: Compression of digitized pictorial data is achieved by comparing a data block of a predetermined size with a group of patterns relevant to that size held in a library. If a match is found the data block is represented by an output signal by a code identifying the pattern. If no match is found the data block is sub- divided into smaller blocks which are compared with another group of patterns. This sub-division process continues until the data is matched or a predetermined minimum size of data block is reached, when the data itself is applied to the output signal. 
     The compressed data may be reconstituted and displayed or used to monitor the progress of a vehicle.

Abstract: Electronic assemblies are fabricated by stacking alternate connecting layers and component layers. The component layers may be virtually any rigid structure having contact regions formed on at least one face thereof. The connecting layers are formed from anisotropic elastomeric conductors which in turn are fabricated by stacking a plurality of conductive sheets and insulating sheets, where the conductive sheets have a plurality of parallel electrically conductive elements formed therein. By introducing a curable elastomeric resin into the stacked structure so formed, and then curing the elastomer, a solid elastomeric block having a plurality of parallel electrically conductive elements running its length is obtained. Individual elastomeric conductors suitable as connecting layers interfacing between adjacent component layers are obtained by slicing the block in a direction perpendicular to the conductors.

Title: Gas turbine engine casing with reduced surface drag
Inventor: PRESZ WALTER M JR
IPC: B63H9/06
Filed: 1987-04-07
Abstract: A casing (202,204), such as for a gas turbine engine (200), surrounds a fluid stream and has an un­bounded fluid flowing over its external surface (212), in a downstream direction. The external surface (212) has formed therein alternating, adjoining troughs (214) and ridges (216) extending in the downstream direction to the trailing edge (210) of the casing (202,204), such that the casing (202,204) has a wave-like shape at its trailing edge (210). This construction reduces and can even elimi­nate boattail drag on the external surface of casings (202,­204) by delaying or eliminating the onset of two-dimen­sional boundary layer separation. Shorter length casings with greater convex curvature may be used with less drag penalty.

Title: Light fixture housing
Inventor: THIELE KARL-HEINZ
IPC: F21V15/01
Filed: 1988-02-09
Abstract: The housing consists of a light fixture upper part (10) and a light fixture trough (11) which seals the upper part (10) below. Both the light fixture upper part (10) and the light fixture trough (11) are provided on the outside with a fine-grained structure. As a result, the entire light fixture housing acquires a uniform matt outer surface. Reflections of extraneous light are avoided owing to the light-scattering effect of the grained structure of the light fixture trough, and so unevennesses in the light fixture trough do not become visible by reflection. The light-scattering properties of the light fixture trough (11) are improved. <IMAGE>

Abstract: A packaging material which comprises a pair of inflation film layers disposed symmetrically and joined through a pseudo-adhesive portion formed by blocking thereof. 
     In the packaging materials of the invention, a pair of inflation film layers is joined to each other by blocking in a flexible state to some degree without using adhesive. 
     Therefore, they are not always joined completely integrally, and little space remains between the inflation film layers. The space can be increased by controlling the properties of the inflation film layers, blocking conditions and the like. By this pseudo-adhesion, physical strength such as tear strength is improved, buffer action is imparted, and curling is prevented.

Abstract: A folding mop frame has a pair of lateral outer sections (8) pivoted on a central section (2) of the frame and resiliently engagable by that central section to hold them extended with all the sections co-planar. On the upper faces of the lateral sections, near their outer ends, are S-form resilient hangers (34) which grip the ends of a mop head (40) extending around the ends of the frame and over its bottom face. Simply by applying a downwards force to the outer sections (8), they can be released from their engagement with the centre section (2) and swing downwards to leave the mop head hanging loosely, in which state it can easily be wrung out. Because of the resilient nature of the S-form hangers (34), they can ensure the mop head (40) is held taut across the bottom of the frame independently of any shrinkage of the mop head material due to wetting.
