Filed: 1999-03-31
Abstract: L'invention concerne un processeur d'images comprenant une mémoire morte reprogrammable (EPROM) (38) dans laquelle sont mémorisées des données de coefficient relatives à l'agrandissement et à la réduction d'images, des commandes de lecture (40 à 44) permettant par ailleurs de lire ces données de coefficient provenant de ladite mémoire EPROM (38), selon un signal de sélection d'agrandissement/de réduction. Ce processeur d'images comporte également un filtre caractéristique variable horizontal (16) destiné à effectuer un agrandissement ou une réduction d'images en fonction desdites données de coefficient, un autre filtre caractéristique variable vertical (18) étant en outre prévu pour effectuer l'agrandissement ou la réduction d'images en fonction des données de coefficient susmentionnées. Ce processeur d'images est également pourvu d'une mémoire de trames (20), d'un circuit de correction des contours (14), et de sélecteurs (22 à 30). Si ces sélecteurs (22 à 30) sélectionnent l'agrandissement d'images, le signal d'entrée vidéo est traité successivement par le circuit de correction des contours (14), la mémoire de trames (20), et les filtres (16, 18). Si c'est la réduction d'images qui est sélectionnée, ce signal d'entrée vidéo est traité par les mêmes dispositifs mais dans l'ordre inverse. Ainsi, la partie ne devant pas subir une amélioration des contours n'est pas soumise à cette amélioration pendant l'agrandissement d'images, et les composantes haute fréquence améliorées par correction des contours pendant la réduction d'images ne disparaissent pas, ce qui permet d'obtenir une correction des contours appropriée, et ce que l'on sélectionne le traitement, l'agrandissement, ou la réduction d'images.

Title: Improved piezoelectric ceramic-polymer composites
Inventor: IQBAL ZAFAR
IPC: H01L41/45
Filed: 1999-01-07
Abstract: This invention relates to compositions and processes for the fabrication of piezoelectric composites having improved figures of merit for both sensor and non-sensor applications. These composites comprise piezoelectric particles embedded in a polymer matrix. The improvements of this invention result from discoveries of the effects of polymer bulk compliance, polymer anisotropy, polymer melt index, and polymer/ceramic wettability on performance. The loss corrected figure of merit (ghdh/tan.delta.) obtained for the 0-3 composites is as high as 10.5 x 10-10 m2/N, which is about four times higher than previously published for 0-3 composites of the prior art. Methods are described for the introduction of anisotropy into ceramic particle/polymer composites, so that cancellation effects that degrade the piezoelectric properties of composites can be reduced.

Title: Method for treating fibrous webs
Inventor: DETTLING BERNHARD
IPC: D21H25/00
Filed: 1999-01-11
Abstract: The present invention concerns a method for treating the surface of a fibrous web by mechanical grinding. According to the invention, the grinding is performed at substantially dry state by removing only the higher parts of the paper surface without substantially increasing the density of the web. By reducing the roughness of the surface by a maximum of 90 %, the strength properties of the web remain essentially unchanged or they are even improved. Thus, when the roughness of the surface is reduced by about 40 to 60 %, the tear strength increases with more than 5 % in comparison to an untreated web. Papers and boards treated by the present method can be used for printing, packaging and wrapping.

Inventor: MULLER GERD M
IPC: H04R25/00
Filed: 2000-09-18
Abstract: A mechanical coupling for an output-side driver of an active or passive implantable hearing system. The driver is adapted to vibrate a preselected site on a member selected from the group comprising the ossicular chain, the footplate of the stapes and a membrane which closes a window in one of the cochlea, the vestibulum and the labyrinth (equilibrium organ), via a first coupling which has a coupling rod, which can be caused to vibrate mechanically by the driver, and a coupling element which can be connected to the preselected coupling site. The coupling rod and the coupling element are interconnected by at least one coupling. The first coupling half of the coupling has a roughly cylindrical outside contour that can be accommodated in the inside contour of a second coupling half, i.e. a contour which is at least partially complementary to the outside contour. In the implanted state, transmission of the dynamic forces between the two coupling halves of the coupling takes place essentially in the direction of the longitudinal axis of the first coupling half. The coupling can be reversibly coupled and decoupled and can be adjusted in a reversibly linear and/or rotational manner with reference to the longitudinal axis of the first coupling half, whereas the coupling is essentially rigid under the dynamic forces which occur in the implanted state.

Title: Production of tertiary amine oxides
Inventor: COCHRAN REBECCA S
IPC: C07C291/04
Filed: 1999-03-12
Abstract: Exothermic oxidation of tertiary amine with aqueous hydrogen peroxide in an aqueous reaction medium formed or being formed from tertiary amine, aqueous hydrogen peroxide, carbon dioxide, and optionally chelating agent and/or additional water, is initiated at 15 to 25 ~C, and while agitating the reaction mixture, the temperature is allowed to rise adiabatically to a temperature in the range of 50 to 100 ~C. In this way, it is possible to produce tertiary amine oxides with very low levels, if any, of nitrosamine impurity, without addition of metal and/or phosphorus-containing components recommended in the priot art. Even though a substantial portion of the reaction is performed at temperatures in the range of 50-100 ~C, nitrosamine content, if any, in the resultant tertiary amine oxide product can be well below 30 ppb, and the free amine content, if any, can be well below 0.3 wt.%.  Use of such relatively exothermically achieved high temperatures in turn results in faster reaction rates and enables use of shorter reaction periods.

Title: Method and apparatus for detecting proper mailpiece position and feeding
Inventor: JACOBSON GARY S
IPC: B65H1/14
Filed: 2000-11-22
Abstract: The present invention is directed to, in a general aspect, a nudger for a mixed mail feeder and, in particular, to an apparatus and method of providing and detecting proper position in a stack of mixed mail. The apparatus, generally, comprises a nudger arm for detecting proper positioning of the mailpiece and a lean detection arm for detecting proper lean of the mailpiece with respect to the nudger. The method comprises generally, a determination that when the lean detection arm and the nudger arm are in a position indicating that the lead mailpiece is in the proper position, the stack of mixed mail is decelerated and fed to, for example, a separator, for further processing. The deceleration is performed at a slow rate and provides for a predetermined amount of over travel by the stack of mixed mail. This ensures proper contact of the lead mailpiece with the nudger rollers for feeding the mailpieces for further processing. The nudger rollers continue to feed the lead mailpieces until one or both of the lean detection arm and the nudger arm move out of the position(s) for proper mailpiece feeding.
