Title: Microstrip cross-coupling control apparatus and method
Inventor: SHIH CHIEN-FU
IPC: H01P1/20
Filed: 2000-03-22
Abstract: The present invention provides for a method and apparatus to control non- adjacent cross-coupling in a micro-strip filter. In instances of weak cross- coupling, such as a filter circuit on a high dielectric constant substrate material (e.g., LaAIO3, with dielectric constant of 24), a closed loop is us ed to inductively enhance the cross-coupling. The closed loop increases the transmission zero levels. For strong cross-coupling cases, such as a filter circuit on a lower dielectric constant substrate material (e.g., MgO with dielectric constant of 9.6), a capacitive cross-coupling cancellation mechanism is introduced to reduce the cross-coupling. In the latter instance , the transmission zero levels are moved down.

Title: Method and apparatus for sorting items of mail
Inventor: BAYER THOMAS
IPC: B07C3/14
Filed: 2000-08-08
Abstract: The invention relates to sorting items of mail in a plurality of sorting passes. In order not to have to read the address in each sorting pass and also not to have to print any machine-readable identification code on each item of mail, features characteristic of the items of mail are additionally determined during the first sorting pass and are stored together with distribution codes determined in the reading process.  During the subsequent sorting passes only the characteristic features of the items of mail are measured and compared with the stored features. In the event of agreement, the item of mail is assigned the associated distribution code. A particular feed regime with defined orders ensures that in each case only n items of mail have to be compared, where n = maximum multiple delivery rate to be expected.

Abstract: A television having a program rating function according to a set-up value of a program rating set up by a user and a method for controlling the same. The television has: a judgment unit for judging the program rating based on a program rating signal included in a received broadcasting signal; a set-up value storage unit for storing the set-up value of a program rating set up by the user; a display unit for displaying the program rating judged by the judgment unit; and a control unit for controlling the display unit to display the program rating judged by the judgment unit, when there is no set-up value in the set-up value storage unit. Therefore, when the programs are broadcasted in a situation in which the user has not set up the set-up value of the program rating due to the inconvenience of a V-chip (Violence-Chip), it is reported to the user that the television includes the above function through a display unit. Accordingly, programs can be watched by a suitable audience and the practical usage of the television having the function of the program rating is improved.

IPC: G06F3/147
Filed: 2000-12-21
Abstract: La présente invention concerne une technique de reconnaissance de formes, utilisant un automate fini, qui intègre une séquence d'opérations de recherche dans une table. Une séquence de paramètres d'entrée, dérivée en fonction d'un algorithme d'application spécifique, génère une séquence correspondante d'adresses de mémoire pour ces opérations. Les tables de mémoire sont organisées dans une structure hiérarchique qui correspond à la séquence d'entrée. Des données de table sont conçues pour reconnaître une bibliothèque spécifique de formes d'entrée. Une séquence d'entrée trace un chemin spécifique d'entrée, à travers les tables de mémoire, jusqu'à ce qu'une des formes de la bibliothèque soit reconnue (578) ou jusqu'à ce qu'il soit déterminé que la séquence d'entrée est incompatible avec toutes les formes de la bibliothèque. Pour chaque forme de bibliothèque, les données de table sont conçues pour s'adapter aux variations des valeurs d'entrée qui sont spécifiques à l'application (des variations dues au bruit et/ou aux tolérances, par ex.). Des données de table peuvent être dérivées par analyse, simulation, apprentissage ou une combinaison de ces procédés. Cette invention peut remplacer des réseaux neuronaux ou des techniques de corrélation par traitement numérique du signal dans des applications en temps réel. Cette invention permet de parvenir à une très grande efficacité, par comparaison de la séquence d'entrée à toutes les formes de la bibliothèque, de manière simultanée. Cette invention peut être mise en oeuvre afin d'améliorer la qualité d'image d'un système à balayage cavalier, qui utilise la technologie d'affichage par écran plat. La présente invention concerne également un procédé permettant d'améliorer l'efficacité de systèmes d'affichage qui utilisent des mémoires d'image, afin de rafraîchir une image générée par ordinateur.
