Title: Inflatable tube ski vehicle with steering mechanism
Inventor: OBERPRILLER BARRY G
IPC: A63C5/00
Filed: 2002-07-16
Abstract: An inflatable tube ski vehicle with steering mechanism comprises an inflated, torus- or delta-shaped tube or bladder and a ski insert disposed in the central opening of the bladder. The ski insert may be dish-shaped, or it may partially wrap around the top and/or bottom of the bladder. In either case, the ski vehicle has a steering/braking mechanism comprising left and right lever arms pivotally attached to and extending down through the ski insert. To turn, a rider simply pulls on one of the lever arms, causing a lower portion of the lever arm to extend past a bottom of the insert. To brake, both arms are pulled simultaneously. Because the ski vehicle is generally round and because the weight of the vehicle and rider are largely uniformly distributed over the center of the vehicle, a pivot or fulcrum point occurs directly under the rider's seat, affording a significant degree of control.

Title: Embolic protection devices
Inventor: WHITFIELD JOHN D
IPC: A61M25/00
Filed: 2001-01-16
Abstract: An embolic protection device for use in a blood vessel when an interventional procedure is being performed in a stenosed or occluded region to capture any embolic material which may be created and released into the bloodstream during the procedure. The device includes a filtering assembly having a self-expanding strut assembly and a filter element attached thereto. In one embodiment, the filtering assembly is attached to the distal end of a guide wire and is deployed within the patient's vasculature as the guide wire is manipulated into the area of treatment. A restraining sheath placed over the filtering assembly in a coaxial arrangement maintains the filtering assembly in its collapsed position until it is ready to be deployed by the physician.  Thereafter, the sheath can be retracted to expose the filtering assembly which will then self-expand within the patient's vasculature. Interventional devices can be delivered over the guide wire and any embolic debris created during the interventional procedure and released into the blood stream will enter the filtering assembly and be captured therein. Other embodiments include filtering assemblies attached to an outer tubular member and inner shaft member which apply axial force to the distal ends of the assembly to either expand or contract the struts as needed.

Title: Insulation carrying and cutting device
Inventor: CHEEK JERRY
IPC: B26D9/00
Filed: 2002-10-29
Abstract: A device and method for simultaneously cutting and scoring pieces of insulation consisting of thick fiber on a foil backing, for joining pieces of insulation. A dolly is provided for carrying a fifty-pound roll of insulation so that insulation can be pulled from the roll and over an attached cutting surface. Two parallel rotary knives move together across the insulation on the cutting surface. One knife cuts through both the fiber and foil. The other knife simultaneously makes a parallel cut 1.5 inches from the first, through the fiber but not the foil, so that the fiber between the two cuts can be removed from the foil. The foil from which the fiber has been removed, can then be overlapped onto the foil of another piece of insulation to join the two pieces.

Title: Method and apparatus for continuously fractionating and analyzing metal mercury and water-soluble mercury in gas
Inventor: ITO SHIGEO
IPC: G01N1/10
Filed: 2001-06-25
Abstract: A method for continuous fractional analysis of metallic mercury and water- soluble mercury in a gas, which comprises rendering an absorbing solution (7 ) to absorb the water-soluble mercury contained in the gas, separating the gas  from the absorbing solution (7), reducing the water-soluble mercury in the absorbing solution (7) to covert it to a metallic mercury dispersed in a gas  and introducing the gas into an analyzer (20), and, at the same time, introducing the metallic mercury which has not been absorbed by the absorbin g solution (7) and remains in a form dispersed in the gas to an analyzer (22);  and an apparatus for practicing the method. The method allows the water- soluble mercury and the non-water-soluble mercury to be captured and measured/analyzed in separate measuring systems as different chemical forms of mercury, and also allows monitoring and displaying the respective concentrations of metallic mercury and water-soluble mercury in a gas continuously in real time. It is preferred that an acidic gas being an inhibiting component for the measurement of mercury is absorbed by the absorbing solution (7) together with water-soluble mercury.

Abstract: An eye chart of the present invention has a plurality of symbols selected from a set of distinct symbols. The symbols in the set consist of numerals of 3, 4, 6, 7, and 9 and letters of A, E, F, H, J, K, L, P, T, X, and Y. In one embodiment, the symbols in the set further include a pictorial object. A  method for vision testing of the present invention includes recording a value associated with an accuracy of identification of at least two of the letter, the numeral, and the pictorial objects on an eye chart by a person, and comparing the values for each eye of the patient. Because these symbols are distinct, the value recorded for visual acuity is accurate and consistent with each recordation. Further, the values are able to be used as aids in testing for neurological disorders or diseases. In another embodiment, the eye chart has symbols of red colors and of black colors. In another embodiment, the eye chart has variously colored symbols on colored backgrounds. Accuracy of identification of these colored symbols is recorded, compared, and used as an aid in diagnosing loss of color vision.
