Abstract: The inventors have isolated novel genes with a high homology to the T.  lanuginosus lipase gene and are thus well suited for use in gene shuffling.  Accordingly, the invention provides a method of generating genetic diversity into lipolytic enzymes by family shuffling of two or more homologous genes which encode lipolytic enzymes. The DNA shuffling technique is used to create a library of shuffled genes, and this is expressed in a suitable expression system and the expressed proteins are screened for lipolytic enzyme activity.  The expressed proteins may further be screened to identify lipolytic enzymes with improved properties. The invention also provides a polynucleotide comprising a nucleotide sequence encoding a lipolytic enzyme and a lipolytic enzyme (a polypeptide with lipolytic enzyme activity).

Patent CA-2445480-A1 (CA)
Inventor: CROCKETT BRETT G
IPC: G10L21/04
Filed: 2002-04-25
Abstract: Distortion artifacts preceding a signal transient in an audio signal stream processed by a transform-based low-bit-rate audio coding system employing coding blocks are reduced by detecting a transient in the audio signal strea m and shifting the temporal relationship of the transient with respect to the coding blocks such that the time duration of the distortion artifacts is reduced. The audio data is time scaled in such a way that the transients are temporally repositioned prior to quantization in a transform-based low-bit- rate audio encoder so as to reduce the amount of pre-noise in the decoded audio signal. Alternatively, or in addition, in a transform-based low-bit-ra te audio coding system, a transient in the audio signal stream is detected and a portion of the distortion artifacts are time compressed such that the time duration of the distortion artifacts is reduced.

Title: Organosilicon containing compositions for enhancing hydrocarbon production and method of using the same
Inventor: DAWSON JEFFREY C
IPC: C09K8/508
Filed: 2004-03-05
Abstract: Compositions useful in the reduction of excessive water in oil and gas wells and other subterranean formations comprises an organosilicon compound and a relative permeability modifier (RPM) macromolecule. The RPM is capable of impeding the production of water. The organosilicon compound is capable of forming a water-soluble silanol by hydrolysis and is preferably either an organosilane halide or organosilane alkoxide. The composition is introduced into the subterranean formation for the purpose of selectively reducing excessive production of aqueous fluids. The composition may be employed in well treatment fluids introduced into production wells or injection wells. The compositions may also be utilized in conjunction with stimulation treatments and with introduction of other well treatment fluids. By introducing the composition into fluid passages of the formation, the water producing zones can be selectively blocked off. Thus, the ability of fluids to flow through the aqueous fluid containing fluid passages is selectively reduced resulting in the reduced production of aqueous fluids while maintaining production of hydrocarbons. Core flow test results show effectiveness at permeability as high as 7.0 Darcy under high rate flow conditions.

Patent CA-2471941-A1 (CA)
Inventor: STINSON JONATHAN S
IPC: A61F2/90
Filed: 2003-01-03
Abstract: Une prothèse endovasculaire (16) insérable dans le corps comprend des segments tubulaires séparés disposés en une séquence alternée de segments possédant une rigidité axiale élevée (22) et de segments possédant une rigidité axiale faible (24). Les segments à rigidité axiale plus faible (24) sont destinés à être placés le long des zones plus courbées du vaisseau sanguin, de sorte que la prothèse épouse mieux les formes du vaisseau. Les segments plus souples axialement peuvent être fabriqués par enroulement d'un faisceau métallique ou polymère selon un pas supérieur le long desdits segments, ce qui permet l'obtention d'un angle de tressage supérieur dans une prothèse tressée. Dans ces cas-là, les segments plus souples axialement exercent également une force radiale supérieure lorsque la prothèse est comprimée radialement. Autrement, la prothèse peut consister en de multiples faisceaux tressés entre eux, chaque faisceau comportant un nombre plus élevé de filaments (au moins deux) le long des segment rigides axialement, et comportant un nombre inférieur de filaments (au moins un) le long des segments souples axialement. Dans une autre version, le dispositif est formé d'un ou plusieurs faisceaux élastiques, chaque faisceau comportant un filament biostable et un filament bioabsorbable, de sorte qu'après l'implantation la force radiale et la rigidité axiale diminuent in vivo.

Title: System and method for acoustic two factor authentication
Inventor: GANTMAN ALEXANDER
IPC: G06F21/31
Filed: 2003-02-12
Abstract: A hand-held token can be operated to generate an acoustic or other wireless signal representing a digital signature produced from the private key of a public key pair (44), with the public key being confidential in that it is known only to authorized entities, such as bank computers. The signal from the token can be received by, e.g., a receiver at a bank ATM (46) that also requires a PIN for account access. The user enters the PIN into the ATM (48), and the ATM (52) encrypts the signal from the token with the PIN and sends it on to the bank computer (54) over a link that need not be secure, since even if the PIN is guessed there is no way to verify that it is the correct PIN  without also knowing the confidential public key held by the bank computer.
