Title: Method for strengthening the implementation of ecdsa against power analysis
Inventor: LAMBERT ROBERT J
IPC: H04L9/32
Filed: 2003-04-04
Abstract: A method of inhibiting the disclosure of confidential information through power analysis attacks on processors in cryptographic systems. The method masks a cryptographic operation using a generator. A secret value is combined with the generator to form a secret generator. The secret value is divided into a plurality of parts. A random value is generated for association with the plurality of parts. Each of the plurality of parts is combined with the random value to derive a plurality of new values such that the new values when combined are equivalent to the secret value. Each of the new values is used in the cryptographic operation, thereby using the secret generator in place of the generator G in the cryptographic operation. The introduction of randomness introduces of noise into algorithms used by cryptographic systems to mask the secret value and protect against power analysis attacks.

Abstract: Nature evolves biological molecules such as proteins through iterated rounds of diversification, selection, and amplification. The present invention provides methods, compositions, and systems for synthesizing, selecting, amplifying, and evolving non-natural molecules based on nucleic acid templates. The sequence of a nucleic acid template is used to direct the synthesis of non-natural molecules such as unnatural polymers and small molecules.  Using this method combinatorial libraries of these molecules can be prepared and screened.  Upon selection of a molecule, its encoding nucleic acid template may be amplified and/or evolved to yield the same molecule or related molecules for re-screening. The inventive methods and compositions of the present invention allow for the amplification and evolution of non-natural molecules in a manner analogous to the amplification of natural biopolymer such as polynucleotides and protein.

Filed: 2003-01-22
Abstract: The present invention is directed to a system and method for designing efficient multi-channel FBG gratings using a pre-compensated phase mask for diffracting light for side-writing the grating on an optical fiber core. A desired phase function of the FBG is generated, specifically tailored to an effective spacing between the phase mask and the optical fiber core. From th e phase function a phase mask is pre-compensated to offset diffraction effects associated with each longitudinal position of the FBG receiving light from t wo corresponding longitudinal positions of the phase mask substantially symmetrically spaced longitudinally relative to each particular longitudinal position of the FBG. The two corresponding longitudinal positions of the pha se mask are spaced longitudinally from each other by a spacing determined by th e effective spacing between the phase mask and fiber core and by the first ord er diffraction angle of light through the phase mask. The design involves Fouri er transformation and optimisation process steps for binory phase gratings.</SD OAB>

Position sensors provide actual position feedback. Each flap/slat is driven by two transmissions, namely two drive transmissions, or two guide transmissions, or one drive transmission and one guide transmission. A redundant drive path is ensured if a component fails.

Title: Methods and compositions for extinguishing fires using aqueous gelled fluids
Inventor: TAYLOR ROBERT S
IPC: A62D1/00
Filed: 2004-09-20
Abstract: The present invention relates to improved methods of extinguishing fires or retarding fire propagation by forming a crosslinked water gel which is then applied to the fire or area to be protected. By forming a semi-solid crosslinked gel water can be conveyed over large distances while minimizing losses due to misting, thus making fire fighting from great distances possible and improving the efficiency of aerial drops. The crosslinked gel also has a particularly good adhesiveness and cohesiveness, giving it the ability to form one continuous blanket on the ground thereby smothering the fire and preventing re-ignition. The combination of these properties makes the crosslinked gel ideal for applications such as control and extinguishing of forest fires. In addition, the composition may include additional active ingredients such as herbicide, pesticide, fungicide fertilizer, or the like for soil remediation after the fire is extinguished.
