Patent AU-5890799-A (AU)
Title: Character recognition
Inventor: SPARR GUNNAR
IPC: G06K9/42
Filed: 1999-08-25
Abstract: Character recognition includes detecting a union of characters, preprocessing the union of characters, comparing the preprocessed union of characters with one or more template symbols, and applying a decision rule to either reject a template symbol or decide that the template symbol is included in the union of characters. Such preprocessing involves representing the union of characters as one or more curves, and parameterizing the curve(s); and, regarding various classes of transformation, forming one or more shapes for the curve(s). The comparing operation involves forming one or more geometric proximity measures, and determining for every shape the values of those measures between the shape and correspondingly determined shapes for the template symbols. Applying a decision rule involves selecting one or more template symbols in consideration of the values.

Title: Light source with adjustable wavelength for an oximeter
Inventor: DIAB MOHAMED KHEIR
IPC: H05B44/00
Filed: 1996-06-04
Abstract: The method and apparatus of the present invention provides a system wherein light-emitting diodes (LEDs) (162) can be tuned within a given range by selecting their operating drive current in order to obtain a precise wavelength. The present invention further provides a manner in which to calibrate and utilize an LED probe (150), such that the shift in wavelength for a known change in drive current is a known quantity. In general, the principle of wavelength shift for current drive changes for LEDs is utilized in order to allow better calibration and added flexibility in the use of LED sensors, particularly in applications when the precise wavelength is needed in order to obtain accurate measurements. The present invention also provides a system in which it is not necessary to know precise wavelengths of LEDs where precise wavelengths were needed in the past. Finally, the present invention provides a method and apparatus for determining the operating wavelength of a light-emitting element such a light-emitting diode. <IMAGE>

Title: Preparation of hydrolysed zirconium salt precursors and high purity zirconia
Inventor: HOUCHIN MARTIN RICHARD
IPC: C22B34/14
Filed: 1987-06-05
Abstract: In the economic production of hydrolysed zirconiferous precipitate, hydrolysis is carried out by the addition of base to aqueous acidic zirconium sulphate solution, to lower the H<+> to and maintain within a pH range of 3 to 7, preferably within 4 to 6. The base may be selected from ammonia, basic ammonium salts, e.g., ammonia-buffered ammonium salts, an alkali metal hydroxide, carbonate or bicarbonate. Specific bases include ammonia and ammonium/sodium/potassium hydroxide, carbonate or bicarbonate, with particular preference for ammonia and ammonium/sodium hydroxide. The starting materials may be incorporated in batchwise or continuous fashion, batchwise by combining them in a body of water, suitable electrolyte or solvent with thorough continuous mixing or continuously by mixing them together in a flowing stream. An additive in the form of an inorganic stabiliser or an organic surfactant may also be included. Inorganic stabilisers may be selected from one or more of Y2O3, Ce2O3, Al2O3, MgO and CaO or precursors thereof. In the finishing stage, either further base may be added to lower residual sulphate content or acid added to remove acid-soluble impurities. The precipitated product is then separated, (e.g., by filtration), washed and calcined to give pure zirconia. High purity zirconia has particular application in the electronics industry and for the production of partially stabilised zirconia ceramics.

Abstract: A process of enhancing both the activity and the methane selectivity of a Dispersed Active Metal ("DAM") hydrogenation catalyst is disclosed wherein the DAM undergoes low temperature oxidation in a slurry phase to form an oxidized catalyst precursor that is unique in comparison to those formed by conventional high temperature deactivation processes. The oxidized catalyst precursor, which is stable, is subsequently reduced to form an enhanced catalyst by treatment with hydrogen-containing gas at elevated temperature. The process is useful in a wide variety of DAMs formed by art-recognized techniques. The process is equally applicable to the enhanced catalysts formed from the oxidized precursors and their use in hydrogenation reactions.
