Title: Intravenous fluid heating system
Inventor: SHIGEZAWA GORDON Y
IPC: H05B1/02
Filed: 2000-08-22
Abstract: A medical tubing is used for heating an intravenous fluid immediately prior to the fluid's introduction into a patient. The medical tubing comprises an internal web with a heating element along a length of the web, which heats fluid passing through the tubing. Temperature sensors at an entrance and exit of the tubing communicate the temperatures of the unheated and heated fluid, which provides a feedback control circuit for regulating the amount of heat delivered to the fluid. Current carrying wires in the web dissipate heat and thereby heat the web, which in turn heats the fluid in the tubing. A heat controlling unit adjusts an electrical current transmitted to the current carrying wires in the web. The web may be formed separately from the tubing and subsequently inserted therein, or formed integrally with the tubing by, for example, an extruding process. The web is of sufficient thickness to carry the heating element and additionally carry a separate line for the temperature signals, yet remain flexible so that the tubing can be used in the traditional manner.

Filed: 2000-09-18
Abstract: A simple optical position encoder of detecting the position of a light spot generated by any light source of either light generating or light reflecting type, directly in a binary or other encoded format at very high speed, comprises a diffractive optical element including an array of diffractive cells each being formed by a unique arrangement of diffractive sub-cells and being disposed at a predetermined position with respect to a predetermined reference point on the diffractive optical element. Each cell is capable of generating a unique optical diffraction pattern when illuminated. When an image of the light spot is formed on the diffractive element, at least one cell is positioned to receive the light spot input image, generating its unique optical diffraction pattern accordingly at an output image plane, where one or more optical detectors are disposed. The detectors are responsive to the unique optical diffraction pattern to generate one or more encoded signals indicative of the position of the light spot image with respect to said reference point. Described applications of the basic embodiment of the position encoder includes absolute three-dimensional position measurement of a light spot formed on a object, position encoding of a light peak generated by an optical processor or correlator and absolute/relative position detection of a light spot generated by or reflected onto an object in a two-dimensional coordinates system.

Abstract: A method for quantifying a DNA binding protein in a biological sample. The method may be used in the absence of radioisotopes, and at a sensitivity greater than the commonly used electrophoretic mobility shift assay (EMSA) method previously discussed. In particular, the method includes the steps of: a) treating the sample to obtain a liquid to be tested for the DNA binding protein, b) incubating the liquid containing the DNA binding protein with a DNA, containing a binding sequence to which DNA binding protein can specifically bind so that DNA binding protein specifically binds to the DNA, c) separating the DNA with bound DNA binding protein from other DNA and proteins in the liquid, and e) quantifying the DNA binding protein without interference from other proteins of similar molecular weight in the absence of the use of a radioisotope, and at a sensitivity greater than EMSA. The amount of DNA binding protein may be quantified in several ways, e.g.  directly by immunoreaction to the DNA binding protein or indirectly by amplification of DNA specifically bound to the binding protein followed by quantification of the amplified DNA. In a further embodiment of the invention, the total protein in the sample, having at least one specific immunoreactive site in common with the DNA binding protein, is quantified and compared with the quantity of binding protein to give an indication of relative proportions of bound and unbound protein in the total protein.

Abstract: A router has a network topology table and a number of resource tables corresponding to network areas. In response to a user's request, one of entries of the topology table and one of the resource tables are referenced and a traversable area along the route to the destination and links of the area which satisfy a user-specified QoS value are selected. A calculation is performed on the selected links according to the Dijkstra algorithm to find a shortest path to the destination if the referenced entry indicates that the destination is in the local area of the muter. If the entry indicates otherwise, the calculation is continued until a shortest path tree is found for all area border routers of the traversable area or until the calculation terminates if that tree is not found for all such routers, and a route having an optimum QoS value is determined from the shortest path tree.

Title: Non-invasive blood pressure sensor with motion artifact reduction
Inventor: ARCHIBALD G KENT
IPC: A61B5/022
Filed: 1999-10-18
Abstract: A non-invasive blood pressure sensor (22) includes a first fluid filled sensing chamber (A) having a diaphragm (168). A first transducer (26a) is fluidly coupled to the first sensing chamber (A) to sense fluid pressure within the first chamber (A). A flexible body conformable wall (164) surrounds the sensing chamber (A). The wall (164) applies force to the artery while preventing pressure in a direction generally parallel to the artery from being applied to the sensing chamber (A). The flexible body conformable wall (164) includes a second fluid filled chamber (F). A second transducer (26b) fluidly coupled to the second chamber (F) senses fluid pressure in the second chamber (F). As varying pressure is applied to the artery, pressure wave forms are sensed by the first transducer (26a). Using output signals of the first, and second transducers (26a, 26b), the sensed pressure waveform data is analyzed to derive waveform parameters from which blood pressure values are derived.  The effects of motion artifacts are reduced by the use of signals from both the first, and second transducers (26a, 26b).

Title: Snowmobile with pivotable rear snow flap
Inventor: GIROUARD BRUNO
IPC: B62D55/08
Filed: 2001-06-12
Abstract: A snowmobile includes a chassis having a generally reduced length and a snow flap pivotally attached to the rear portion of the chassis, above the track system. The track system extends rearwardly beyond the chassis, and the snow flap shields the track system above and behind from spraying snow. The snow flap is linked to the track system so that as the track system moves through a range of travel relative to the chassis, the snow flap pivots relative to the chassis with the track system. This configuration prevents damaging contact between the tread and the undersurface of the snow flap and/or the chassis. The reduced length of the chassis decreases the weight of the snowmobile and the polar moment of inertia, thereby improving turning performance. A bumper extends from the snow flap and can be used to lift the rear of the snowmobile more easily. 20
