Title: Flexible container made of film material and filling method for filling such a container with a fluid substance
Inventor: KUYVENHOVEN COR
IPC: B65D30/20
Filed: 2000-06-29
Abstract: The application relates to a flexible container (3) made of film material for containing drinks, comprising a fill opening as well as film storage means which delimit a first compartment and a second compartment (17, 18, 19) of the container and which release a second compartment (18, 19) when a predetermined degree of filling of the first compartment (17) is reached. By means of the film storage means, which, for example, can be formed by folding the side strips (20, 21) double in the longitudinal direction and holding them in place with the aid of adhesive tape, adhesive or fusion welding of the film material, uniform filling of the first compartment can be obtained, the flexible container largely remaining out of contact with the walls of the surrounding outer container. When the first compartment (17) has been filled the film storage means are released by the increase in the fill pressure and the second compartment (18, 19) can be filled so that uniform contact of the flexible container with the wall of the outer, rigid container is obtained. Using the flexible container and using the filling method according to the present invention high fill rates can be achieved and stresses are prevented from becoming too high in certain sections of the flexible container.

Patent CA-2392602-A1 (CA)
Inventor: GUNDRY KENNETH J
IPC: G10L19/02
Filed: 2000-11-29
Abstract: A multidirectional audio decoder using an "adaptive" audio matrix derives at  least one of a plurality of output audio signals from two or more directionally-encoded audio input signal streams (S1(.alpha.), S2(.alpha.), ...SN(.alpha.), wherein .alpha. is the encoded angle of a source audio signa l. Each output signal is associated with a principal direction .beta.. In order  to generate each output signal, a pair of intermediate signals ("antidominan t" signals) are generated, constituting the antidominant signal for each of the  two adjacent principal output directions of the decoder. The antidominant signal for any arbitrary principal (or "dominant") direction is the combination of input signals having coefficients such that the combination goes to zero for that dominant direction. Amplitude control is applied to th e two antidominant signals to deliver a pair of signals having substantially equal magnitudes that are additively or subtractively combined to provide th e output audio signal associated with a principal direction.

Title: Encoding method and system resistant to power analysis
Inventor: CHOW STANLEY T
IPC: G07F7/10
Filed: 2001-02-19
Abstract: New techniques for cracking sealed platforms have recently been discovered which observe power modulation during execution of a software encryption program on a computer processor. Particularly vulnerable to such simple powe r analysis and differential power analysis attacks are smart cards which emplo y Data Encryption Standard (DES) protection. The invention protects against su ch attacks by mapping data onto "Hamming-neutral" values, that is, bytes which have the same number of 1-values, so power signatures do not vary during execution. The Hamming-neutral values are assigned to each bit-string in a targeted data set, rather than in a bit-wise manner as known. This approach has a number of advantages: it is less demanding of system resources, it results in a larger number of encodings for an attacker to decipher, and it can be applied to various components including: addressing, indexing, stored  data and input data. Many variations and improvements are also described.</S DOAB>

In one embodiment, human dendritic cells exposed to a tumor associated antigen, or an antigenic fragment thereof in combination with bacillus Calmette-Guerin (BCG), are administered to a cancer patient to activate a predominantly CD8+T cell response in vivo. In an alternate embodiment, human dendritic cells are exposed to a tumor associated antigen or a specific antigenic peptide in combination with BCG in vitro and incubated or cultured with primed or unprimed T cells to activate a predominantly CD8+T  cell response in vitro. The activated T cells are then administered to a cancer patient. Antigen in combination with BCG is processed by dendritic cells through the MHC-CLASS I compartment which provides for a predominantly CD8+T cell response. The addition of LPS provides for a greater number of mature dendritic cells enhancing the T cell response to antigen. Methods and compositions for human dendritic cells with extended life span and cryopreserved dendritic cells are disclosed.
