Title: Lactose-containing food composition for infants
Inventor: SAYAMA KOUJI
IPC: A23C9/18
Filed: 1996-09-18
Abstract: The present invention provides the lactose-containing food compositions for infants for improving the stool color of infants closer to that of breast-fed infants, which comprises the lactose-containing foods for infants of which the only protein source is substantially cow's milk protein and/or a processed product of cow's milk protein modified to be administered to infants, and raffinose added into the foods for infants at a ratio of at least 0.05% (by weight) in a ready-to-use state.

Inventor: ADAMS JOHN M
IPC: A61N1/39
Filed: 1998-04-07
Abstract: An implantable atrial defibrillator includes a lead system having a plurality of electrodes to deliver a cardioverting pulse to atria of a heart, for sensing A waves of the heart, and for sensing R waves of the heart.

Title: Methods and apparatus for distributed control of a multi-class network
Inventor: VICKERS RICHARD
IPC: H04Q3/66
Filed: 1998-04-30
Abstract: Methods and apparatus for control of a multi-class digital network are described. The network supports a plurality of digital services using dynamically-configured service bands to support various transport modes and qualities of service. Flexible controls with two degrees of freedom are used at the node level to dynamically configure the transport bands. The first degree of freedom is realized using adaptive alternate routing to balance the traffic intensity across the network and, hence, increase the efficiency of the band. The second degree of freedom is achieved through adaptive network partitioning to provide elasticity to the band structure. This permits band capacity to be adaptively reconfigured as connections are added and dropped. The switching nodes use rate controllers to divide the capacity of each link among the connection classes according to rules which ensure consistent service attributes for each band across the network. The rate controllers are adapted to support different transport modes and different packet sizes so that the deconstruction and reconstruction of packets at network edge devices is eliminated. The advantage is a flexible multi-class network which dynamically reconfigures to service traffic loads as service demands fluctuate.

Title: Radar-based method of measuring the level of a material in a container
Inventor: LUBCKE WOLFGANG
IPC: G01F23/284
Filed: 1998-06-04
Abstract: For measuring the level of a material in a container on the basis  of  the  radar  principle,  microwaves  are  radiated downwards and reflected microwaves received by means of the antenna of a ranging device arranged above the highest level anticipated.  In the normal measuring operation the received microwaves are evaluated in the distance range up to empty distance corresponding to the distance of the antenna from the bottom  of  the  container  for  determining  the  echo  waves reflected from the surface of the material, for measuring the transit time of the echo waves and for computing the distance of the material surface from the antenna of the ranging device from the measured transit time.  In order to reliably detect the empty condition of a container having a curved bottom, despite the multiple reflections of the microwaves reflected from the container bottom, when no echo waves are detected in the distance range up to the empty distance, the evaluation is done in an enlarged distance range and any echo waves detected in the enlarged distance range beyond the empty distance are assigned to the empty distance.

Title: Procede d'utilisation d'impulsions laser u.v. a densite d'energie variee, pour former des trous borgnes dans des cibles multicouches
Inventor: VAN PUYMBROECK JOZEF
IPC: B23K26/40
Filed: 1997-03-10
Abstract: L'émission d'un laser Nd:YAG (10), déclenché et pompé en continu, subit une conversion de fréquence afin de produire de la lumière ultraviolette (62) pour former des trous (72, 74) dans des cibles (40) possédant des couches métalliques (64, 68) et une couche diélectrique (66). L'invention consiste à employer une première émission laser de densité d'énergie élevée pour pratiquer l'ablation de la couche métallique, puis une seconde émission laser de densité d'énergie plus faible pour pratiquer l'ablation de la couche diélectrique. Les paramètres des impulsions (62) de sortie sont choisis pour faciliter une forage ou une formation de trou sensiblement propre et séquentielle. Ces paramètres comprennent généralement au moins deux des critères suivants: densité d'énergie d'abord supérieure puis inférieure au seuil d'ablation du conducteur, longueur d'onde inférieure à 400 nm, durée d'impulsion inférieure à environ 100 nanosecondes et fréquence de répétition supérieure à environ un kilohertz. Le fait de pouvoir produire des impulsions de sortie de lumière ultraviolette à deux densités d'énergie facilite la formation de trous borgnes avec limitation automatique de profondeur, dans ces cibles multicouches telles qu'une cible composée d'une couche de matériau diélectrique recouverte sur l'une ou l'autre de ses surfaces d'une couche métallique.

Title: Method and apparatus for determining distance
Inventor: NAKAYAMA JOJI
IPC: G01C3/08
Filed: 1998-12-04
Abstract: A method and apparatus for precision distance measurement are provided to perform accurate measurement of distance to an object according to light spots formed on the light receiving surface of a detector even when multiple reflections are involved. A beam of light emitted from a light source and reflected from the object is focused on the viewing surface as light spots through an optical member. The focal position of a reflected beam of light is determined according to a focal position detection process. When there are peaks in a luminosity curve generated on the detector, prior to performing the focal position detection process, the peaks are separated into individual light spots and a correct light spot for deriving the precise distance is selected by a selection process.
