Title: Modulation d'amplitude en quadrature multicanale a large bande de signaux de television par cable
Inventor: PETER MONTA
IPC: H04L27/34
Filed: 2004-04-21
Granted: 2013-06-04
Abstract: L'invention concerne une modulation QAM multicanale directe à la RF à large bande, dans laquelle un traitement IFFT est mis en oeuvre pour moduler en parallèle une pluralité de trains de symboles codés (202A, 202B, 202n) sur une pluralité de supports uniformément espacés de même nature. Une horloge maîtresse haute fréquence et des convertisseurs numériques-analogiques à haute fréquence et haute performance (210) sont employés. Le processus de modulation IFFT produit un multiplexage multivoie à une fréquence de la "bande de base" intermédiaire. Le multiplexage multivoie est alors converti de manière synchrone sous forme analogique et décalé vers le haut de manière synchrone par déplacement de fréquence par une moitié de la fréquence de l'horloge maîtresse, au moyen d'un plan de mélange doublement symétrique en quadrature (222A, 222B, 222n). Le multiplexage multivoie codé résultant occupe une bande de fréquence centrée autour d'une moitié de la fréquence de l'horloge maîtresse. Des techniques multivoies peuvent être employées pour réaliser un traitement numérique à grande vitesse à partir d'une logique numérique incapable de fonctionner directement à la fréquence de l'horloge maîtresse.

Abstract: A method for the seamless switching of a wireless device between wireless wide area networks (WWANs) and wireless local area networks (WLANs) includes automatically detecting the available WWANs and WLANs, selecting one of the available networks for use by the wireless device, and connecting the wireless device to the selected network. The method also includes maintaining the network connectivity (112) by monitoring the connection and, upon determining that the connection has been lost (114), selecting another available network for use and connecting the wireless device the other network (120). Additionally, the method communicates information about the availability networks and connection status to a user of the wireless device, which allows the user to manually switch the wireless device connection from the automatically selected available network to another available network. Further, a wireless device implements the above-described method.

Title: Hyaluronan (ha) esterification via acylation technique for moldable devices
Inventor: JAMES SUSAN P
IPC: C12N/
Filed: 2004-09-20
Granted: 2011-01-11
Abstract: A series of novel, melt- or mold-processable HA esters with varying aliphatic chain lengths are synthesized from silyl HA-quaternary (quat.) ammonium salt complex (preferably silyl HA-CTA, a silylated HA complex with cetyltrimethyl ammonium salt). Introduction of aliphatic acyl groups, preferably acid chlorides, to disrupt the strong HA intermolecular bonding, is done via acylation. Acylation takes place at the oxygen of the trimethylsilyloxy group -0-Si(CH3)3 in the silyl HA-CTA by removal of trimethylsilyl. groups therefrom. Optionally, crosslinking may be performed during the shaping/molding of the HA esters into a structure/device, or thereafter, if at all. Native HA can then be regenerated/recovered by saponification/ hydrolysis, removing acyl groups, -CH3(CH2)10CO, and the cetyltrimethyl ammonium salt groups, -CTA, from HA ester. The structure/device of a preselected shape (e.g., porous or solid, bulk structure or fibers) may become a component of an assembly, a product that is further processed, integrated into another component (e.g., laminated, adhered, assembled, further shaped, chemically-intermixed/intermingled), and so on.

Abstract: A block for forming a wall and the wall thus formed are provided. A plurality of analogous blocks are overlapped staggeringly and continuously in the wall. The block is a longitudinally profiled member, and includes a top surface (1), a bottom surface (2) and two end surfaces (3). The cross section of the block is, as a whole, of a shape of downward-flared recess. The top surface (1) of said block has a mid ridge (4) higher than two sides of the surface so that a left supporting slope and a right supporting slope (5) are formed. The upper surface (1) and bottom surface (2) are formed such that: when the block is overlapped with a analogous block thereunder to form the wall, the left and right supporting slopes are used as a blocking structure and interlock the vertically adjacent blocks. The projecting size of the mid ridge (4) can cut off the space-time trajectory. The invention also provides auxiliary blocks engaged therewith.

Dans le cas d'une salve, les données du détecteur s'accumulent pendant un premier laps de temps et sont transmises par l'émetteur pendant un deuxième laps de temps, qui est plus court que le premier. Lorsque la transmission est terminée, l'émetteur peut être mis hors tension. L'étape suivante consiste en l'affichage en temps réel des données du détecteur par le récepteur. L'affichage est retardé de la somme du premier et du deuxième laps de temps.
