Patent CA-2483877-A1 (CA)
Inventor: NIEMI ANTTI
IPC: D21G9/00
Filed: 2003-05-09
Abstract: In order to observe the dry line formed on the surface of wood fibre pulp on the mov~ing wire in a Fourdrinier paper machine, its- atrea of appearance is scanned at a low an~gle with a thin beam cluster (A1,B1) which, being generated by a laser radiation source (20) and representing one or more discrete wavelengths, is distinguishable from the background light. Hereby t he surface following the dry line (I) reflects diffusively a major part and specularly a minor part of the arriving radiation than the surface preced~in g it. A detector (30) located above the level of the wire observes the intensi ty of the diffusely reflected radiation (A3,B3) hitting it and delivers continuously, as the beam cluster scans the pulp surface, a signal which is proportional to said intensity. The sig~nal is digitized repeatedly and processed in real time in a computer, whereby a series of signals in the direction of the paper machine produces one dry line point and, if re~peated for different positions in the cross direction, the dry line consisting of such points. The dry line and the values of quantities and deviations characterizing it are displayed by graphical and numerical terminals and actuators of the paper machine are controlled according to it automatically, synchronously with the scanning of the dryline region. The method can be implemented also in such paper machine environments, to which the earlier methods for structural reasons do not apply.

Abstract: A low loss, low drive voltage plasmon-polariton electro-optic modulator based on mode cutoff comprises a waveguide structure formed by a thin metallic strip (106) surrounded by material (102, 104) having a relatively low free charge carrier density. The metallic strip has finite width and thickness with dimensions such that optical radiation having a wavelength in a predetermined range couples to the metallic strip and propagates along the length of the metallic strip as a plasmon-polariton wave. The surrounding material comprises two distinct portions (102, 104) with the metallic strip extending between them. The modulator comprises means (108A, 112) for varying an electric field applied to at least one portion so as to vary the value of the electromagnetic property and thereby the propagation characteristics of the plasmon-polariton wave.

Title: Method for improving unpredictability of output of pseudo-random number generators
Inventor: PETERSEN METTE VESTERAGER
IPC: G06F7/58
Filed: 2003-06-06
Abstract: A method for performing computations in a mathematical system which exhibits a positive lyapunov exponent, or exhibits chaotic behavior, comprises varying a parameter of the system. When employed in cryptography, such as, e.g., in a pseudo-random number generator of a stream-cipher algorithm, in a block-cipher system or a HASH/MAC system, unpredictability may be improved. In a similar system, a computational method comprises multiphying two numbers and manipulating at least one of the most significant bits of the number resulting from the multiplication to produce an output. A number derived from a division of two numbers may be used for deriving an output. In a system for generating a sequence of numbers, an array of counters is updated at each computational step, whereby a carry value is added to each counter. Fixed-point arithmetic may be employed. A method of determining an identification value and for concurrently encrypting and/or decrypting a set of data is disclosed.

Inventor: HOFFMAN DOUGLAS B
IPC: A61B17/072
Filed: 2005-06-22
Abstract: A surgical stapling and severing instrument particularly suited to endoscopic procedures incorporates a handle that produces separate closing and firing motions to actuate an end effector. In particular, the handle produces multiple firing strokes in order to reduce the required amount of force required to fire (i.e., staple and sever) the end effector. Varying the center of rotation, circumferential length, and depth of cam lobes in a cam disk that interacts with the firing trigger via a drive wedge allows optimization. In particular, mechanical advantages during specific firing strokes mitigates increased force to fire at the end effector, enabling a more uniform tactile force at the firing trigger.
