Title: Method of determining sites for arrhythmia ablation
Inventor: MARCHLINSKI FRANCIS E
IPC: A61N1/40
Filed: 1994-12-12
Abstract: A method of locating infarcted myocardial tissue in a beating heart includes the step of inserting an impedance measuring tip (10) of a catheter (14) into the chamber of the beating heart and measuring the impedance of the endocardium at various locations within the beating heart. The values measured are compared to impedance values with a predetermined range of values (22) to identify an infarcted area of myocardium and distinguish such area from normal myocardium (20). The measurements are also compared to a range of values for an infarction border zone. The infarction border zone is a significant source of arrhythmia and particularly of ventricular tachycardia. In accordance with the methods of the present invention, the risk of arrhythmia in a beating heart may be substantially reduced or eliminated by ablating endocardium within the infarction border zone utilizing the same catheter tip.

Abstract: Process for eliminating adsorbable organic halogen compounds from wastewaters The invention relates to a process for eliminating adsorbable organic halogen compounds from an aqueous phase, in particular from wastewater or from a process solution, in which the aqueous phase is treated with a nonaqueous extraction medium in a liquid-liquid extraction, which comprises, after the extraction, subjecting the adsorbable organic halogen compounds to a Wurtz-Fittig reaction in the extraction medium.          Only small amounts of noncritical products such as NaOH and HCI, which can be readily removed, are formed in the nonaqueous extraction medium.          By means of this process, the cost of the chemicals which conventionally arises in the elimination of the adsorbable organic halogen compounds is considerably decreased.

Title: Method and instrument for selecting personal compatible colors
Inventor: MACFARLANE DARBY S
IPC: G01J3/52
Filed: 1994-05-09
Abstract: Skin coloration categories are identified based upon opponent color undertones of the skin. For example, using a color measuring device (10), Hunter b value is developed from measures of blue, yellow and lightness. That value alone then determines which of several categories of skin coloration a subject's skin exhibits. Category selection is made by comparison of measured Hunter b with ranges of Hunter b values of skin color categories. Instrumentation includes the color measuring device (10), a central processing unit (15), memory (17), and an output device. The skin color Hunter b is calculated and compared to stored ranges to assign a category which is then displayed on the output device. Colors compatible with skin color categories are identified or formulated based upon broad color family designation, yellow, brown, red, etc., and a comparison of measured and stored ranges of known or specifically developed color characteristics for the particular family.

Title: Textured epoxy powder coating for wood substrates and method of coating wood therewith
Inventor: CORRELL GLENN D
IPC: C09D163/00
Filed: 1997-04-10
Abstract: Thermosetting powder coating compositions adapted to form a grainy textured finish on heat sensitive substrates, especially wood products, such as particle board, conductive particle board, and medium density fiber board, without damaging the substrates comprise an epoxy resin, particularly bisphenol A type epoxy resins having low viscosities, either a catalytic curing agent comprising an imidazole, a substituted imidazole, or adduct of an imidazole or substituted imidazole and an epoxy resin, or a curing agent comprising an adduct of a polyamine and an epoxy resin, or a combination of the catalytic curing agent and curing agent, a texturing agent, a flow control agent, optional extender, and optional pigment. The thermosetting powder coatings have a cure time/temperature ranging from about 30 seconds at about 350°F peak substrate temperature down to about 20 minutes at about 225°F peak substrate temperature which provides for either a rapid cure or low bake temperature to prevent excessive heat exposure to the heat sensitive substrate, resulting in substantially no physical or chemical degradation of the heat sensitive substrate during baking. The powder coatings are applied to heat sensitive substrates, especially wood products, through electrostatic spraying onto the substrate followed by heating to cure the textured finish uniformly on the surfaces and edges of the substrate. Electrostatic spraying is performed with a triboelectric or corona spray gun and heat curing is performed with a high intensity infrared oven, a convection oven, or combination. Coated heat sensitive substrates having continuous grainy textured finishes that are excellent for hiding substrate surface defects and later appearing scratches are obtained.

Title: Speech recognition system and method with automatic syntax generation
Inventor: GRONER GABRIEL F
IPC: G10L15/28
Filed: 1996-01-25
Abstract: A syntax rule authoring system automatically generates syntax rules for an application program's predefined inputs, thereby enabling the application program to be used with a syntax based speech recognition system. The syntax rule authoring system includes memory (104) for storing an application program having an associated set of user selectable predefined inputs. The syntax rule authoring system stores in a first data structure for each predefined input an associated longest word sequence for uniquely identifying that predefined input. A word sequence generation procedure automatically generates, for each predefined input, a set of potential identifying word sequences. Each generated potential identifying word sequence includes a subset of the words in the associated longest word sequence. The potential identifying word sequences for all the predefined inputs are stored in a second data structure. A redundant word sequence elimination procedure identifies redundant sets of matching word sequences in the second data structure, where each redundant set of matching word sequences includes potential identifying word sequences for at least two distinct predefined inputs whose word sequences satisfy predefined match criteria. A syntax generation procedure then generates syntax rules, each generated syntax rule corresponding to those of the potential identifying word sequences for a distinct predefined input that are not included in any of the identified redundant sets. The generated syntax rules are suitable for use in a syntax based speech recognition system.
