Title: Speech-recognition circuitry employing phoneme estimation
Inventor: KROEKER JOHN P
IPC: G10L21/02
Filed: 1988-04-08
Granted: 1994-05-03
Abstract: ABSTRACT OF THE DISCLOSURE      A phoneme estimator (12) in a speech-recognition system (10) includes trigger circuitry (18, 22) for identifying the segments of speech that should be analyzed for phoneme content.  Speech-element processors (24, 26, and 28) calculate the likelihoods that currently received speech contains individual phonemes, but they operate only when the trigger circuitry identifies such segments.  The computation-intensive processing for determining phoneme likelihoods is thus performed on only a small subset of the received speech segments.  The accuracy of the speech-element processors (24, 26, and 28) is enhanced because these processors operate by recognition of patterns not only in elements of the data-reduced representations of the received speech but also in higher-ordered products of those elements; that is, these circuits employ non-linear modeling for phoneme identification.

Title: Homogeneous protection assay
Inventor: ARNOLD LYLE JOHN JR
IPC: C12Q1/6827
Filed: 1988-09-21
Granted: 1998-05-19
Abstract: Improved homogenous diagnostic assay methods  and labels  for detecting an analyte  in a medium when  the analyte is a member of a specific binding pair.   The methods  and  labels  provide  procedures  for  reducing background  and  increasing  sensitivity.    The  binding partner of the analyte is labeled with a substance, the stability  of  which  detectably  changes  whenever  said analyte  is bound as a member  of  the specific binding pair.    In  a closely  related  system,  the  analyte  is labeled  with  a  substance  susceptible  to  differential degradation depending on whether or not the analyte is bound as a member of its specific binding pair.   After incubation  and  selective  degradation  or  chemical  or biochemical alteration,  the amount of analyte bound is detected by measuring either the stability change or the extent of degradation of  the  label.   In a particular system, chemiluminescent acridinium ester labeled probes are used in a homogenous hybridization assay format for sensitively  detecting  the  presence  of  complement  any target polynucleotide sequences.

Abstract: Abstract:            Method for the pretreatment of a lumpy carbon carrier Suggested is a method of pretreatment of a lumpy carbon carrier suitable for forming a fluidized bed and a solid bed used in the production of pig iron fron iron ore. The ore is pre-reduced in one or a plurality of reduction plants  and the thus produced iron sponge is subsequently fused in a melt-down gasifier with the help of the lumpy carbon carrier and an oxygen-containing gas and is final reduced. Thereby the carbon carrier is fed into the upper part and the oxygen-containing gas is fed in to the lower part of the melt-down gasifier. These materials form, together with the iron sponge, a fluidized bed in the melt-down gasifier. Below same, a solid bed is formed consisting of said lumpy carbon carrier. For such carbon carrier are used either lumpy coal tending to burst on shock-like thermal load, which is subjected to a pre-treatment aiming at diminishing this bursting tendency prior to it being fed into said melt-down gasifier, or fine coal blended with a binder and granulated, which was preferably ground prior to admixing said binder.

Granted: 1993-05-04
Abstract: ABSTRACT    A directional guidance device, for deflecting a drill bit  away  from  the  longitudinal  axis  of  a  substantially horizontal  section  of  a  wellbore,  takes  advantage  of gravitational  force  to  move  a deflector  member  therein between first and second positions.  In the first position, the deflector member prevents the drill bit from advancing past  the  directional  guidance  device.   In  the  second position, the deflector member allows the bit to pass out of the guidance device,  and deflects the bit away from the longitudinal axis of the horizontal section of the wellbore.          A  method  of  producing  hydrocarbons  includes  drilling a wellbore   including   a  slanted,   substantially  straight section, a substantially curved section, and a substantially straight,  substantially  horizontal  section.   The  slanted section is drilled at an angle of approximately 60°  from horizontal and the curved section is drilled at an angular rate of build of approximately 7?° per 100 feet.  Multiple offset wells are drilled from the substantially horizontal section  at  an  angle  of  approximately  30°  from  the longitudinal axis of the substantially horizontal section.

Abstract: MECHANICALLY DRIVEN AUGER SYSTEM     ABSTRACT OF THE DISCLOSURE         An auger system comprises a main auger with a longitudinal auger flight extending from a container at the bottom of the main auger to a discharge spout at the top of the main auger.  The lower end of the main auger is connected by a hitch member to a tractor and the lower end of the main auger flight is connected to a PTO shaft of the tractor.  A side load auger extends from a hopper at the lower end to a discharge spout connecting into the container at the lower end of the main auger.  A mechan-ical drive connection extends from the main auger shaft to the feed auger shaft and comprises a chain drive coup-ling driving a second shaft parallel to the main auger shaft at a position above the main auger shaft.   Two right angle gear boxes are mounted with one inside the container and the other inside the discharge spout of the side load auger.   The gear boxes are connected so that the second shaft drives the input shaft of the container gear box which in turn drives the input shaft of the spout gear box through a universal coupling.   The uni-versal coupling also provides physical support for the spout relative to the container.   The mechanical drive system reduces horsepower requirement and also provides a fixed drive ratio between the side load auger and the main auger to maximize the  feed capacity of the main auger.

Title: Surface mount technology breakaway self regulating temperature heater
Inventor: HENSCHEN HOMER E
IPC: H05K1/02
Filed: 1989-09-25
Granted: 1992-11-10
Abstract: ABSTRACT:    Soldering of surface mount connector terminals to contact pads on a circuit board is facilitated by configuring the terminals and their solder tails as spaced integrally-formed projections of a selectively actuable heater.  Thermal energy developed in the heater is conducted along the projections to the solder tails to melt fusible conductive material (e.g., solder, at the connection sites).  After cooling, the projections are severed from the heater.  The terminals, which are formed at the distal ends of the projections, are typically supplied partially inserted in respective terminal-receiving passages of the connector housing.  After the soldering operation, the terminals are fully inserted into the passages.  The heater is preferably a self-regulating heater in the form of a copper substrate having a skin layer of magnetically permeable, high resistance material.          An alternating current of constant amplitude and high frequency is passed through the heater and concentrated in the skin layer at temperatures below the Curie temperature of the skin layer material.  At higher temperatures, the current is distributed through the lower resistance substrate to limit further heating.  During the time interval required for the surface layer to reach its Curie temperature, the resistive power dissipation creates thermal energy that is conducted to the solder tails.

Abstract: HEATED WIPER BLADE ASSEMBLY                     ABSTRACT OF THE DISCLOSURE   A heated wiper blade assembly for windshields is provided, in which a plastic blade holder has an upper longitudinal groove for receiving a flat electric heating element enclosed in a ribbon of dielectric.  The plastic blade holder also has at its lower portion, a longitudinal slot for receiving a wiper blade therein.  A metal cap is positioned over the heating element and crimped around the plastic holder to form a wiper blade subassembly.  Such subassembly is then mounted in an enclosing wiper housing such that the upper portion of the blade holder with heating element and metal cap or radiator, are positioned within the housing cavity and the lower portion of the blade holder and the wiper blade, face away from the housing, so that upon application of electricity to the heating element, heat is directed into the housing and also applied to the holder and indirectly to the wiper blade.  The holder thus protects the wiper blade from direct application of heat and yet is of low cross-sectional profile and is of sufficient flexibility to follow curved windshield contours without early fatigue problems.  The enclosing housing protects the radiator and heating element from wind chill and the radiator directs heat into said housing to warm same.  The housing then reflects said heat back down around the holder and wiper blade and thus provides sufficient heat to minimize or prevent snow and ice build-up on housing and blade.  In another embodiment of the invention, a flat flexible metal blade replaces the metal cap as radiator, to impart added flexibility to the wiper blade assembly.
