Abstract: A multicellular transmission apparatus in a mobile communication network, capable of preventing delay involved in reassembling short packets into fixed length packets (ATM cells), degradation of communication signals due to the delay, and reduction of the transmission efficiency involved in assembling the short packets into the fixed length packets. Then low speed information transmitted from a telephone set (610) is converted into short packets by a communication data assemblers/disassemblers (402) in a mobile gateway switching center, followed by multiplexing of the short packets into the fixed length packets by fixed length packet assemblers/disassemblers (404), the short packets sent from a plurality of telephone sets are grouped for each destination node (a particular radio base station, for example) in the network, and are multiplexed into the fixed length packets belonging to the group bound for the destination of the short packets. This obviates the disassembling/reassembling of the fixed length packets at intermediate switching centers, thereby implementing an effective ATM switching system.

Granted: 2000-09-19
Abstract: Two separate electrooptic phase modulators are used in a modified Mach-Zehnder interferometer to vary the absolute and relative optical phases of two orthogonally polarized modes of an input signal independently of each other. A conventional Y-branch splitter on lithium niobate splits the input signal equally into the two waveguide phase modulators and an external polarization splitter recombines the two phase modulated signals in orthogonal polarization states.  The polarization in the interferometer is maintained by connecting the outputs of the two phase modulators to polarization maintaining fibers.  An alternate embodiment of the present invention uses an additional 3-dB directional coupler to mix the two phase modulated signals before they are combined in orthogonal polarization states.

Abstract: This invention is a method and apparatus for non-invasiveness in determining hematocrit, utilizing the frequency dependent electrical impedance characteristics of whole blood by electrically stimulating a patient body portion containing a vascular compartment with a current source over a range of frequencies. A hematocrit measurement system includes a signal generator and demodulator [SGD] (34) that sends an applied signal to an electrode pod (36) that applies a current to a limb of a patient. The electrode pod (36) receives resulting measured voltage signals and provides them to the SGD. The SGD provides to a personal computer [PC] (42) signals indicative of the current passing through the limb of the patient and the resulting voltage. The voltage and current may be measured for various frequencies over, for example, a range from about 10 kHz to about 10 MHz. The electrical impedance from the blood alone is isolated from the total limb impedance from the blood, tissue, bone, etc. by determining the difference between measurement at different blood volumes. The hematocrit is determined by the PC based on inphase and quadrature data provided by the SGD. A neural network (52) may be useful in determining the hematocrit from the blood impedance patterns.

Title: Internally tin-coated copper pipe and method for coating a copper pipe
Inventor: BAUKLOH ACHIM
IPC: C23C18/31
Filed: 1997-12-19
Granted: 2001-07-31
Abstract: A copper installation pipe having a tin coating that is applied with temperature control so as to be adherent over the entire  inner surface.   The thickness  of  the intermetallic  phase  formed at  the  transition  from the copper pipe to the tin coating is less than 20%, preferably less  than  5%  of  the  overall  coating  thickness.    In addition, a method for coating an installation pipe using chemical treatment, where the temperature of the tinning solution is selectively varied.  To ensure the smallest possible intermetallic phase at the copper surface,  one begins the tinning process at a low temperature.  This promotes the formation of a large number of uniformly distributed  nuclei  of crystallization  having  the  same orientation. The temperature is then selectively adjusted to promote  crystal  growth,  the  result  being  that  the crystals  grow  rapidly  with  the  orientation  remaining constant. One then achieves a dense tin coating having a minimal exposed surface area.

Abstract: Procédé et système comprenant un algorithme informatique à grande vitesse (30) permettant la rotation des images stockées dans une mémoire d'ordinateur (26), telles que celles captées par une caméra à transfert de charge (22). Le dispositif décrit est utilisable avec un lecteur à reconnaissance optique de caractères placé au-dessus de la bande transporteuse (10) qui capte une image pixelisée de la surface d'une paquet (14) se déplaçant le long du convoyeur (12). Selon le mode de réalisation préféré, on obtient une image de sortie codée sur la longueur du passage à partir d'une image d'entrée codée sur la longueur du passage, l'image de sortie (17') étant une version après rotation de l'image d'entrée (17). Une séquence de mappage de pixels prédéfinie correspondant à un angle de rotation avec une tangente rationnelle est utilisée pour mapper les pixels de l'image. Le mappage des pixels de l'image au moyen d'une séquence de mappage de pixels prédéfinie permet une rotation sans calculs à la virgule flottante, et permet l'utilisation d'une technique de mappage de pixel inverse permettant de mapper les passages de sorties à partir d'une image d'entrée afin d'éviter la création de trous ou d'artefacts dans l'image de sortie. Suivant le procédé décrit, le système met à l'échelle les passages de sortie mappés pour préserver le rapport d'aspect de l'image après rotation. Le système choisit l'ordre dans lequel les éléments de la table d'entrée sur la longueur du passage sont traités de façon à créer directement une table de sortie codée sur la longueur du passage.
