Title: Monitoring fluid condition through an aperture
Inventor: EDROZO FRANCIS CHRISTOPHER
IPC: G01N33/28
Filed: 2000-10-30
Abstract: A method for real time monitoring fluid in a vessel with a probe having a pair of electrodes immersed in the fluid. The disclosed probe has the electrodes arranged helically on a rod, sized and configured for insertion in an engine dipstick hole.  Preferably, the probe has spiral electrode winding up regions different pitch to provide improved impedance response at fractional Hertzian and Hertzian frequencies of excitation. In one version with alternating voltage the difference in current magnitude measured at the fraction Hertzian and Hertzian frequencies compared with stored known values for known fluid conditions and an electrical signal indicative of fluid condition is generated. Examples with engine drain oil and heavy duty transmission lubricant fluid are presented. The impedance properties measured can determine the percentage remaining useful life (RUL) of the fluid. In another version of the method the current phase shift angle is measured at the fractional Hertzian frequency; and, from known values of current phase shift angle of the fluid, at various conditions, the condition of the fluid determined. The differential current measured and the measured phase shift angle may be combined, for example, by the square of the sum of the squares procedure to provide an enhanced impedance change indicator.

Patent CA-2331442-A1 (CA)
Inventor: YUNG MARCEL M
IPC: H04L9/30
Filed: 1999-05-21
Abstract: The invention provides for robust efficient distributed generation of RSA  keys. An efficient protocol is one which is independent of the primality test "circuit size", while a robust protocol allows correct completion even in the presence of a minority of arbitrarily misbehaving malicious parties. The disclosed protocol is secure against any minority of malicious parties (which is optimal). The disclosed method is useful in establishing sensitive distributed cryptographic function sharing services (certification authorities, signature schemes with distributed trust, and key escrow authorities), as well as other applications besides RSA (namely: composite ElGamal, identification schemes, simultaneous bit exchange, etc.). The disclosed method can be combined with proactive function sharing techniques to establish the first efficient, optimal-resilience, robust and proactively-secure RSA-based distributed trust services where the key is never entrusted to a single entity (i.e., distributed trust totally "from scratch"). The disclosed method involves new efficient "robustness assurance techniques"  which guarantee "correct computations" by mutually distrusting parties with malicious minority.

IPC: B60C9/02
Filed: 2001-03-09
Abstract: A method for the manufacture of the reinforcement structure of the tire in standard production process in which a carcass ply cord is oriented. to follow the direction of real forces in the tire (1), rolling on the road (2) where each surface point of the tire follows the cycloid curve (3). This is to withstand a stress an the each point when it is accelerated from zero velocity while touching the road (4), to double velocity of the vehicle, while at the top of the tire (wheel) (5), and a stress when it is decelerated back to the zero (6). The strength and density of the ply cord has to meet requirements to withstand a stress which repeats with every turn of the wheel and increases by square of the real velocity. Former designs meet tension forces only in a stationary rotating tires. Forces of the real rolling movement and accelerations on the cycloid path are until now ignored.  This neglect causes structural faults of the tire, among other (production) reasons. For better appreciation of the invention significance, let us consider a tire of a jet landing by 300mph having all surface paints accelerated from zero - when touching the runway -to 600mph plus, when on the top of the wheel, then decelerating back to zero. This repeats by each turn of the wheel. The accelerating stress is combined with the load pressure.  This invention provides means to withstand this stress.

Title: Guidage d'un catheter par mappage magnetocardiographique
Inventor: FENICI RICCARDO
IPC: A61B5/296
Filed: 1999-12-06
Abstract: L'invention concerne un cathéter constitué d'un tube de forme sensiblement cylindrique et subdivisé longitudinalement en plusieurs lumières distinctes parallèles, à travers lesquelles plusieurs fils conducteurs peuvent passer et des guides être insérés, ces guides présentant une extrémité distale à courbure variable. Ce cathéter est également composé de fibres optiques destinées à fournir de l'énergie sous la forme d'une émission laser, ou d'un autre type de dispositif d'ablation. Des électrodes amagnétiques distales permettent par ailleurs un mappage haute résolution de multiples potentiels d'action monophasés dans le site d'apparition de l'arythmie, ainsi qu'une localisation magnétocardiographique du cathéter et une éventuelle modification du substrat électrophysiologique, grâce à l'énergie fournie sous la forme d'une émission laser. On peut manipuler le cathéter de cette invention dans le coeur du patient avec une extrême précision, grâce à l'aspect variable de la courbure de ladite extrémité distale qui permet son insertion dans des gaines extérieures préformées. On fait ainsi coïncider au mieux les coordonnées tridimensionnelles de ce cathéter avec celles du substrat arythmogénique, lesquelles sont définies de manière non invasive par imagerie magnétocardiographique.
