Title: Measuring concentration of elements in gases by spectrometry
Inventor: OTTAWAY JOHN MICHAEL
IPC: G01N21/74
Filed: 1982-09-14
Abstract: For rapid-response measurement of the concentration of an element present in a gas as a constituent of particles therein, eg for monitoring the concentration in air of toxic metals like beryllium, successive fixed volumes of the gas are directed as a jet through the injection hole in the wall of the atomisation tube of an electrothermal atomic absorption spectrometer (ETAAS) so that entrained particles are collected on its inside surface by impaction. After each collection the tube is heated to atomise the collected particles, measurement of the element is effected by conventional AAS technique, and the tube is thereafter cleansed. The measurements are preferably standardised after every so many collections by injection of a known amount of the element as an aerosol.
Patent GB-2107102-A (GB)
Title: Speech recognition apparatus and method
Inventor: MOSHIER STEPHEN LLOYD
IPC: G10L15/10
Filed: 1982-09-21
Abstract: A speech recognition method and apparatus for detecting and recognizing one or more keywords in a continuous audio signal are disclosed. Each keyword is represented by a keyword template which corresponds to a sequence of plural target patterns, and each target pattern comprises statistics representing each of a plurality of spectra selected from plural short-term spectra generated according to a predetermined system for processing the incoming audio. The target patterns also have associated therewith minimum and maximum dwell times. The dwell time is the time interval during which a given target pattern can be said to match incoming frame patterns. The spectra are processed to enhance the separation between the spectral pattern classes during later analysis. The processed audio spectra are grouped into multi-frame spectral patterns and each multi-frame spectral pattern is compared by means of likelihood statistics with the target patterns of keyword templates. Each formed multi-frame pattern is then forced to contribute to the total word score for each keyword as represented by the keyword template. Thus the keyword recognition method requires all input patterns to contribute to the word score of a keyword candidate, using the minimum and maximum dwell times for testing whether a target pattern can still match an input pattern, and wherein the frame rate of the audio spectra must be less than one-half the minimum dwell time of a target pattern. A concatentation technique employing a loosely set detection threshold makes it very unlikely that a correct pattern will be rejected. A method for forming the target patterns is also described.
