Title: Speech recognition training method
Inventor: BAKER JAMES K
IPC: G10L15/10
Filed: 1985-01-17
Granted: 1987-12-01
Abstract: Abstract of the Disclosure A speech recognition method and apparatus employ a speech processing circuitry for repetitively deriving from a speech input, at a frame repetition rate, a plurality of acoustic parameters.  The acoustic parameters represent the speech input signal for a frame time.  A plurality of template matching and cost processing circuitries are connected to a system bus, along with the speech processing circuitry, for determining, or identifying, the speech units in the input speech, by comparing the acoustic parameters with stored template patterns.  The apparatus can be expanded by adding more template matching and cost processing circuitry to the bus thereby increasing the speech recognition capacity of the apparatus.  Template pattern generation is advantageously aided by using a "joker" word to specify the time boundaries of utterances spoken in isolation.

Abstract: ABSTRACT OF THE DISCLOSURE          Apparatus for panoramic X-ray photography of the area of the dentition and the jaws has a bearing part linearly movable in relation to a frame part, and a support arm rotatably attached by bearings to the bearing part with, at opposite ends an X-ray film and a source of X-radiation.   The movements of the bearing part, the support arm and the film are mutually synchronized so that an image of,  for example, an area the shape of the patient's dental arch, is obtained on the film during the movement.   The X-ray beam can be tilted to the desired angle in relation to the horizontal plane, whereby it is possible to photograph with greater sharpness than previously, for example, slanted teeth.  The support arm is attached with bearings to the bearing part 80 as to be tiltable about an axis perpendicular to the rotational axis of the support arm so that, when the rotational axis is vertical, the straight line connecting the source of radiation and the film is oblique to the horizontal level. The structural parts between the bearing part and the support arm have curved guide means which work in conjunction with each other and the mutual movement of which alters the tilt position of the support arm.  The control movements are preferably performed by means of a stepping motor.

Abstract: Abstract The method and apparatus for generating start of combustion signals associated with the combustion events in a diesel engine (10), and for using such signals to control the timing of fuel delivery to the engine.  The combustion event is sensed, as by an electrostatic (230, 330) or optical (130, 430) sensor, and signal conditioning circuitry (32) pro-vides a start-of-combustion (SOC) signal (34) which is directly and precisely indicative of the time of the onset of combustion.  The sensors (130, 230) in-clude self-cleaning capabilities (48, 248) for ex-tended operating life on an engine. The sensors may be incorporated in the structure of a glow plug (330, 430). The SOC signal (34) is advantageously supplied to a timing control circuit (26) which delivers a timing control signal (28) to a fuel delivery device, such as the controller (16') associated with a fuel pump (16).  The control circuit (26) stores (65) one or more start of combustion values (SOC*) which indi-cate the desired timing, relative to an engine cycle (24), for the start of the combustion event as a function of speed (25) and load (27).  One or more adjustment signals (.DELTA.SOC) are stored (75) and applied (67, 68) as a function of speed and load to adjust the desired signal (SOC*) such that the control sig-nal (28, SOCc) is corrected for delays.  The actual SOC signal (34) is compared (71) with the desired signal (66) to generate an error signal (72) which may be used to finely adjust the stored (75) .DELTA.SOC signal for particular speed and load conditions.

Abstract: PROCESS FOR THE PRODUCTION OF IMAGES                 ABSTRACT             A polymerising agent is applied to a substrate followed by a layer of a liquid composition containing both a polymerisable residue and a photocurable residue.  The polymerisable residue is polymerised by the polymerising agent first applied so that the layer solidifies but remains photocurable.  Subsequently this solidified layer is exposed to actinic radiation in a predetermined pattern and those parts of the layer that are not photocured are removed by treatment with a suitable solvent.             Typical polymerisable residues include cyanoacrylates, the polymerising agents for which may be water, ammonium hydrides solution, an alkali metal hydroxide solution, or an amine. Typical photocurable residues include acrylates and methacrylates, :            The process is suitable for the manufacture of printing plates and printed circuits,

Abstract: METHOD AND APPARATUS FOR DETERMINING QUALITY      END MASS FLOW RATE OF FLOWING STEAM                            ABSTRACT           A  method  based  on  an  orifice  flow  equation  is provided for determining both the quality and the mass flow rate of steam flowing in a line, such as to an injection well in  steam flooding operations  for recovery of petroleum.   A sample of the steam is drawn off from the steam line through an orifice and is condensed and collected.   The mass of sample collected and the time to collect it give the mass flow rate of the  sample.   Pressure  and  temperature  measurements  at  the sample line orifice together with the measured mass flow rate of the sample and with known constants are used in the orifice flow equation to derive the sample steam quality.   The line steam  also  flows  through  an  orifice,  with  pressure  and temperature measurements thereon.  The desired quality of the line steam is the same as the derived quality of the sample steam, since care is taken to make them the same.  The orifice flow equation is used again, substituting the derived sample steam quality for the line steam quality,  together with the temperature and pressure measurements at the steam line orifice and with known constants, to derive the desired mass flow rate of the line steam.

Abstract: PHASE DISCRIMINATOR AND DATA STANDARDIZER                 Abstract A phase discriminator and data standardizer apparatus measures phase difference between a data signal obtained from a magnetic disk device and a variable-frequency reference data clock.  From the measured phase difference, the apparatus develops a phase differnce signal used to adjust the frequency of the reference data clock in order to reduce the phase difference.  The apparatus includes a multi-state latch circuit that responds to the input data and clock signals by measuring the phase in a phase measurement transition cycle in which only one state variable changes at a time and producing the phase difference signal based upon the measurement.  A gate responds to the measurement transition cycle by producing the phase difference signal.  The apparatus further standardizes the input data so as to provide the data in a format that is predictably standardized in its time relationship to the reference data clock signal.

Abstract: ABSTRACT        An  optical  storage  apparatus  having  an  improved  focus servo means is disclosed.  A focus error signal is obtained by an optical system comprising a pair of photosensors adjacently disposed sharing a boundary therebetween.  The system contains a small number of optical elements.   A laser beam reflected on a disk surface is projected simply on the photosensors, naturally having a circular spot thereon.  The center of the spot is fixed being displaced from the boundary by a predetermined distance, resulting  in  different  photoelectric  currents  outputted  from both photosensors.   Each photoelectric current is amplified by each amplifier having a variable amplification factor which is adjusted such that both amplified currents become equal when the laser beam is just focused to the disk surface.   As the laser beam is defocused on the disk, then the circular spot expands or shrinks, generating a differential current varying in polarity and  amplitude,  as  a  focus  error  signal  for  the  focus  servo means.   Thus,  the dimensional setting of the photosensors is allowed  to  be  rather  relaxed,  because  the  final  setting  is accomplished  by  adjusting  the  amplification  factors  of  two amplifiers which can be performed very easily.   This system is featured  by  its  simple  optical  system  and  an  easy  setting adjustment.    Further modification of the optical spots on the photosensor  is introduced.   Furthermore,  external disturbance caused by a tracking signal is avoidable,  ensuring a reliable operation.
