Patent CA-2347322-A1 (CA)
Inventor: WELIK RALPH
IPC: A61M15/00
Filed: 2001-05-10
Abstract: A portable oxygen dispenser for providing an emergency supply of oxygen-rich gas includes a closed cannister having a top closure portion and a cylindrical side wall defining a cannister axis and diameter and containing a quantity of pressurized, oxygen-rich. A dispensing orifice includes an externally actuable valve at one axial end of said cannister for maintaining said the orifice normally closed. The valve includes a nozzle stem generally arranged along the cannister axis for opening the orifice when an axial force is applied. An annular neck wall is generally concentrically arranged about the nozzle stem and dimensioned to form an annular space between the nozzle stem and the neck wall. A generally conical diffusing member defines a diffusion axis and opposing axial ends, one of which is a dispensing open end dimensioned to substantially correspond to the cannister diameter; the other end is a closed infusion end and is provided with an inlet opening defining an axis generally transverse to the diffusion axis and stem engaging means for selectively applying an axial force to the nozzle stem. The dispensing end is configured to fit over and be supported on the cannister when not in use. The cannister and the diffusion axes are generally aligned and adapted to be placed over the mouth and/or nose of a user. A protective guide extends from the closed infusion end alone the transverse axis into the annular space for slidingly engaging the annular neck wall with little clearance during use when said cannister and transverse axes are generally aligned and oxygen-rich gas is to be released and for substantially limiting the forces applied to the nozzle stem to axial forces along the cannister axis. In this way, forces on the nozzle stem other than the axial forces along the cannister axis are avoided, thus preventing damage to the nozzle stem during use of the diffusing member.

Abstract: L'invention porte sur des techniques qui permettent de réduire une distorsion d'intermodulation au niveau de la sortie d'un circuit actif présentant une non linéarité paire et une non linéarité impaire. Les produits IM3 générés par la non linéarité paire du circuit actif sont annulées au détriment des produits IM3 générés par la non linéarité impaire. L'amplitude et la phase des produits IM3 peuvent être manipulées par réglage de la source et/ou de l'impédance de charge du circuit actif. L'amplitude et la phase des produits IM2 générés par la non linéarité paire peuvent être manipulées par réglage de l'impédance du circuit actif à une fréquence sous-harmonique ou de seconde harmonique (c.-à-d. les fréquences des produits IM2). En accordant ou "adaptant" correctement l'impédance de la source et/ou de la charge du circuit actif à une fréquence sous-harmonique et/ou de seconde harmonique, on peut régler l'amplitude et la phase des produits IM2 de sorte que les produits IM3 résultant de la non linéarité paire annulent approximativement le produit IM3.

Abstract: A fiber grating pressure sensor includes an optical sensing element 20,600 which includes an optical fiber 10 having a Bragg grating 12 impressed therein which is encased within and fused to at least a portion of a glass capillary tube 20 and/or a large diameter waveguide grating 600 having a core and a wide cladding and which has an outer transverse dimension of at least 0.3 mm. Light 14 is incident on the grating 12 and light 16 is reflected from the grating 12 at a reflection wavelength.lambda.1.  The sensing element 20,600 may be used by itself as a sensor or located within a housing 48,60,90,270,300. When external pressure P increases, the grating 12 is compressed and the reflection wavelength .lambda.1 changes. The shape of the sensing element 20,600 may have other geometries, e.g., a"dogbone" shape, so as to enhance the sensitivity of shift in .lambda.1 due to applied external pressure and may be fused to an outer shell 50. At least a portion of the sensing element may be doped between a pair of gratings 150,152, to form a compression-tuned laser or the grating 12 or gratings 150,152 may be constructed as a tunable DFB laser. Also, the axial ends of element 20,600 where the fiber 10 exits the tube 20 may have an inner tapered region and/or a protruding tapered (or fluted) axial section 27 to provide strain relief or improved pull strength for the fiber 10. A temperature grating 270 may be used to measure temperature and allow for a temperature-corrected pressure measurement.  The sensor may be suspended within an outer housing 112, by a fluid, spacers, or other means. The invention may also be used as a force transducer.

Title: Improved system and method for measuring distance between two objects using received satellite transmitted data
Inventor: BOMAN BERTHO
IPC: G01S5/00
Filed: 2001-10-15
Abstract: A global position satellite receiver (GPS receiver) is located in a fixed, undefined location on or in the vicinity of a golf course. The distance and direction between the fixed GPS receiver and a pin or object on the golf course is measured using conventional distance and direction measuring apparatus. This is a first measured leg. A mobile GPS receiver, with computer, is on the golf course. A golf ball is in the fairway of the hole. The fixed GPS receiver receivers first global position satellite signals (GPS Data) from global position satellites in orbit above the earth, the first GPS Data defining a location for the fixed GPS Receiver. The mobile GPS receiver receives second GPS Data from the global position satellites which define a location for the mobile GPS receiver. Both sets of GPS Data are identically contaminated and both location definitions are unreliable in accuracy. The first GPS Data and the second GPS Data are mathematically calculated to derive the distance and direction between the fixed GPS receiver and the mobile GPS receiver. This is a derived leg. The distance and direction between the mobile GPS receiver and the golf ball on the fairway are measured using conventional distance and direction finding apparatus. The is the second measured leg. The derived leg and the second measured leg are mathematically combined to calculate the distance and direction between the fixed GPS receiver and the golf ball. This is the first calculated leg. The first measured leg and the first calculated leg are mathematically combined to calculate the distance and direction between the ball on the fairway and the pin or object. 59

Title: Optical fiber and nonlinear optical fiber, optical amplifier and wavelength converter using the same, and method of making optical fiber
Inventor: HIRANO MASAAKI
IPC: G02B6/10
Filed: 2001-11-13
Abstract: Employed as a structure of a highly nonlinear optical fiber (nonlinear optical fiber) is a double-cladding structure in which a first cladding region 20 and a second cladding region 30 are disposed on the outer periphery of a core region 10. Since the double-cladding structure is employed, the cutoff wavelength .lambda.c can sufficiently be shortened even when, in order to increase the nonlinear coefficient .UPSILON., the concentration of GeO2 added into the core is enhanced so as to raise the nonlinear refractive index, or the relative refractive index difference between the core and cladding is increased so as to reduce the effective area A eff. This realizes an optical fiber or nonlinear optical fiber shortening its cutoff wavelength while having a sufficient nonlinearity, an optical amplifier and wavelength converter using the same, and a method of making an optical fiber.
