Title: Extruding nozzle for producing non-wovens and method therefor
Inventor: KWOK KUI-CHIU
IPC: B05D1/36
Filed: 1999-07-07
Abstract: A parallel plate nozzle for extruding visco-elastic fluidic materials, useable in the manufacture of non-woven materials, and method therefor dispenses a plurality of first and second fluids from a corresponding plurality of first and second orifices to form first and second adjacent fluid flows. The first fluid flows are drawn and attenuated by not more than one corresponding second fluid flow at a second velocity greater than a first velocity of the first fluid flow to form corresponding first fluid filaments, which are preferably relatively continuous and vacillated chaotically. The first and corresponding second fluid flows are spaced as closely as possible to maximize filament drawing efficiency, and adjacent first fluid orifices are spaced sufficiently apart to prevent merging of the first fluid flows prior filament formation.

Title: Remote computer-assisted compliance monitoring system
Inventor: JENKINS WILLIAM M
IPC: G06Q50/00
Filed: 1998-12-21
Abstract: A student user of a client computer system uses a teaching process to promote development of cognitive skills of the student, and a supervisor uses a second client computer to remotely monitor the progress of the student. The teaching process presents various types of stimuli to the student and records student response data which correspond to the stimuli. In addition, the teaching process forms evaluation data from the student response data where the evaluation data represents a con-elation between the student response data for respective stimuli and predetermined correct response data for respective stimuli. Furthermore, the teaching process modifies its own behavior according to the evaluation data to thereby tailor the behavior of the teaching process to the cognitive abilities of the student. The student response data is uploaded to a global student database which is accessible to a supervisor user. The supervisor requests student response data from the global student database and presents the student response data to the supervisor for analysis. The supervisor can use such analysis in direct consultation with the student at a later date or can recommend changes in the behavior of the teaching process to more effectively encourage development of the cognitive ability of the student.

Title: Path optimization in packet-based telecommunication network
Inventor: RAUHALA KRISTIAN
IPC: H04L12/56
Filed: 1998-04-09
Abstract: The invention relates to connection-oriented packet-based telecommunication networks such as ATM (Asynchronous Transfer Mode) and particularly to route optimization in such networks. A network node (20) on the route adds to a packet flow a special packet comprising a unique code which the network node (20) locally uses for identifying the special packet and for associating the special packet to a particular formed connection. If there is a loop on the path (2,BTS1,3) the special packet added to the packet flow returns back to the same network node. When the network node detects that the special packet provided with the unique code returns back, it may conclude that on the path of the connection to which the unique code is associated to, there is a loop that should be eliminated. Thereafter the network node may internally switch an optimal path (1,4,BTS2) bypassing the detected loop (2,BTS1,3).  Furthermore, the network node preferably releases the loop in a manner characteristic of the network. According to a preferred embodiment of the invention also the elimination of the detected loop is based on the use of the special packet.

Title: Plaque composite a ame alveolaire pour parois et portes de semi-remorques
Inventor: LEWALLEN WILFRED E
IPC: B29C44/32
Filed: 1998-08-26
Abstract: L'invention concerne une nouvelle plaque composite (20) utilisée pour former une paroi (28, 30) ou une porte (32) d'un véhicule, comme un semi-remorque (22) ou un fourgon. Chaque plaque composite (20) utilisée dans le semi-remorque (22) est formée de deux couches de recouvrement métalliques (40, 42), par exemple en aluminium ou en acier, entre lesquelles est placé un élément formant âme de plastique thermique alvéolaire (44). Les couches de recouvrement (40, 42) sont liées à l'élément formant âme (44) par un adhésif flexible connu (46). L'élément formant âme (44) est élastique, et peut être fabriqué à partir d'un plastique thermique alvéolaire de faible densité ou de forte densité. Le moussage de l'élément formant âme (44) selon la présente invention réduit le poids de la plaque composite (20) par rapport aux plaques composites formant âmes plastiques solides de l'art antérieur. Le moussage assure également une meilleure résistance à l'arrachement de la plaque composite (20) par rapport à ces plaques composites de l'art antérieur. En outre, le moussage de l'élément formant âme plastique thermique (44) selon la présente invention réduit la contrainte de cisaillage de la couche de liaison entre l'âme et la couche de revêtement, ce qui réduit le risque de décollement des couches de revêtement métalliques (40, 42) par rapport à l'élément formant âme (44) lors des changements de température, qui a toujours posé un problème avec les plaques composites formant âmes solides.

Inventor: WALLMAN STEVEN M H
IPC: G06Q40/00
Filed: 1999-03-05
Abstract: Smaller investors can create and manage on a cost-effective basis a complex portfolio of securities using a mechanism (1, 2) that enables the investor to provide to the system the investor's preferences regarding his portfolio, to generate a portfolio, including fractional shares, that reflects the investor's preferences. The system then permits aggregation of the orders, and netting of orders, generated by multiple investors at various times during the day for execution (5). In addition, the structure (7) of the computer-based system of the present invention allows its cost to be based on access or usage of the system (such as a monthly fee) as opposed to by securities orders entered into the system as per common brokerage. The result is that the investor can create a portfolio of directly owned securities with attributes, such as diversification, similar to a mutual fund.

Title: Application of light at plural treatment sites within a tumor to increase the efficacy of light therapy
Inventor: CHEN JAMES C
IPC: A61N5/06
Filed: 1999-04-30
Abstract: Light is administered during photodynamic therapy (PDT) for an extended period of time at a plurality of sites (52) distributed within the abnormal tissue of a tumor (22). A clinical study has shown that a substantially greater volume of abnormal tissue in a tumor is destroyed by the extended administration of light therapy from a plurality of probes (50a-50e) than would have been expected based upon the teaching of the prior art. In this process, a plurality of light emitting optical fibers or probes are deployed in a spaced apart array. The greater volume of necrosis (38) in the tumor (22) is achieved due to one or more concomitant effects, including the inflammation of damaged abnormal tissue, and resultant immunological response of the patient's body;  and the collapse of the vascular system that provides oxygenated blood to portions of the tumor outside the expected fluency zone.
