Patent CA-2775325-A1 (CA)
Inventor: JOYE MARC
IPC: H04L9/30
Filed: 2012-04-24
Abstract: A modular exponentiation comprising iterative modular multiplications steps and taking as input a first modulus N, a secret exponent d and a base x.  During at least one modular multiplication step aiming at computing a result c from two values a, b and the first modulus N so that c = a.cndot.b mod N, a processor (120) takes as input the two values a, b and the first modulus N from which are obtained two operands a', b' and a second modulus N' using operations with at most linear complexity -at least one of the two operands a', b' is different from the two values a, b, and the two operands a', b' are different when a is equal to b - so that the modular multiplication c = a.cndot.b mod N from a side-channel viewpoint behaves like a modular squaring except for when a' equals b'. An intermediate result c' = a'.cndot.b' mod N' is computed, and the result c is derived from the intermediate result c' using an operation with at most linear complexity; and the result c is used in the modular exponentiation.

Title: Method and system for non-mechanical rapid tuning of an optical parametric oscillator
Inventor: WOJCIK MICHAEL
IPC: H01S5/04
Filed: 2012-06-15
Abstract: An OPO is disclosed capable of rapid frequency tuning by non-mechanical means. The OPO includes a resonant cavity including one or more non-linear crystals in an optical path thereof. A pump laser pulse is transmitted into the resonant cavity simultaneously with a seed beam having a desired wavelength. The output beam from the resonant cavity has the same center wavelength as the seed beam. The wavelength of the seed beam may be modulated at a frequency larger than the pulse rate of the pump laser or larger than the inverse of the pulse duration. The OPO disclosed may be used to perform DIAL analysis wherein intra-pulse modulation of an output beam is used to obtain measurements of absorption at multiple frequencies for each pulse of a pump beam.

Abstract: A powder cyclone separator for use in a powder coating system is contemplated that is formed in two separate and separable sections. An upper section of the cyclone is mounted on a first frame and remains stationary. A lower section of the cyclone is mounted on a second frame that is movable laterally away from the first frame so that an operator has more ready access to clean interior surfaces of the upper section. Optionally, actuators may be provided to vertically raise and lower the cyclone lower section with respect to the cyclone upper section. Various optional alignment means are presented for aligning the cyclone upper and lower sections. Preferably, a control mechanism is mounted on the second frame which includes a switch that is manually operated by the user to raise and lower the lower section with respect to the upper section. This design allows an operator to see, and therefore verify, that virtually all internal surfaces of the cyclone have been effectively cleaned.

Title: Seismic transducers and baseplates having external dampeners and methods of use
Inventor: EICK PETER M
IPC: G01V1/155
Filed: 2011-02-17
Abstract: Methods and systems are provided for inducing seismic vibrations into subterranean formations. Seismic transducers may comprise a frame, a reaction mass, a driver, and a baseplate. The driver actuates the reaction mass, imparting a vibratory energy to the baseplate. This vibratory energy is then imparted directly to the ground surface to propagate seismic waves into the formation. These seismic waves are then reflected by subsurface geological features. The reflected seismic waves may then be detected and interpreted by seismic detectors to reveal seismic information representative of the surveyed region. An external dampener may be secured to the baseplate, which provide, among other benefits, a damping effect to the baseplate. Advantages include, reduced undesirable baseplate harmonic distortion or "ringing," reduced baseplate decoupling, and reduced seismic noise due to flexure reduction and more uniform baseplate-to-ground conformance. These advantages translate to improved seismic surveys, having higher formation resolution and reaching greater depths.

Abstract: Unique aeroplane wing profiles substantially increasing the aerodynamic qualities of the wing are proposed. The advantage of the proposed profiles and novel method for forming lifting force for a wing on the basis of said profiles is the complete shifting of the interaction of the windstream onto the lower contour, the complete liberation of the upper contour from interaction with the windstream, leading to the elimination of wave drag - an insurmountable defect in wings with a classic profile, and a substantial increase in lifting force for the wing. Novel solutions are given which were the basis for a basically novel interpretation of the process of flow around a wing by the windstream and of the formation of excess pressure along the lower surface.
