Abstract: ABSTRACT OF THE DISCLOSURE         Disclosed is an apparatus for verifying data written on an optical disk by simultaneously reading the data during writing and using differential detection to verify that the data has been written correctly.  The data is written in a fixed-block format defining a symbol having a predetermined number of symbol positions and a predetermined number of holes which may be written in the symbol positions, an equal number of holes in the odd positions and in the even positions.  In this regard, the holes written in the odd positions are independently verified from the holes written in the even positions.  Immediately after the laser has been operated at write power, it is returned to read power and a signal associated with the hole associated power of the reflected beam is sampled.  This signal is compared to the signal power generated at the previous even or odd position.  The highest signal is re-tained and compared to the next even or odd position's signal.  At the end of the symbol, the location of the even and odd symbol positions having the highest signal power is determined and compared to the location of the write pulse to determine whether the location of the hole corresponds with the location of the write pulse.

Title: Method for burning rate characterization of solid  propellants
Inventor: LILLEY JAY S
IPC: G01N33/22
Filed: 1985-04-01
Granted: 1987-04-07
Abstract: ABSTRACT OF THE DISCLOSURE   A method for determining the burning rate of a pro-pellant.  The method involves the single firing of a subscale, propellant motor that has been modified so that the propellant motor has a tapered cylindrical port that produces a non-neutral pressure-time trace when burned.  The pressure-time trace is initially progressive (pressure increases with time), and then regressive (pressure decreases with time).  Unlike conventional motors, this motor operates over a range of burning rates; therefore, the burning rate behavior of the propellant can be characterized with a single motor firing.   The burning rate of the propellant is extracted from the motor pressure-time history by a computer analysis package.          The analysis package employs an optimization program which uses an internal ballistics model of the motor. The ballistics model is used to generate a theoretical pressure-time trace which can be compared with the digitized output signal from the actual motor.  The optimization routine of the computer determines the propellant burning rate behavior by selecting the burning rate law which, when employed in the internal ballistics model of the motor, produces the best match between the computer generated and the actual motor pressure-time traces.  Thus by using the tapered port motor and by reducing the data, the burning rate of a pro-pellant can he characterized with a single motor firing.

Abstract: ABSTRACT            A speech coding and decoding technique involves filtering of blocks of digital samples of speech signals to be coded by a linear prediction inverse filter, whose coefficients are chosen out of a code book of quantized filter coefficient vectors, obtaining a residual signal subdivided into vectors.  The weighted mean square error arising from quantizing these vectors with quantized residual vectors contained in a code book and forming excitation waveforms is computed.  The coded signal for each block of samples consists of the coefficient vector index chosen for the inverse filter as well as of the indices of the vectors of the excitation waveforms which generate the minimum weighted mean square error.  During decoding a similarly coded signal provides the coeffici-ent for a synthesis filter, and quantized residual vectors to excite it.

Abstract: ABSTRACT            ELECTROCHEMICAL ASSAY FOR CIS-DIOLS          The  invention disclosed  relates  to  an electrochemical assay which is particularly concerned with an assay for the presence of,  or amount of, glycosylated haemoglobin in a blood sample, but which extends a general assay for detecting the presence of,  monitoring the level of or determining  the  concentration  of  compounds  containing cis-diol   groups,   such   as   glycols,   nucleic   acid components,  sugars,  polyols,  catechols and glycosylated proteins.            When ferrocene boronic acid or a derivative thereof is present free in solution, it can act as a mediator for a wide range of oxido-reductases.  However in the presence of,   for   example,   sugars   containing   the   cis-diol structure,  the  metallocine  (such as  ferrocene  boronic acid) covalently binds to the sugar.  When the ferrocene boronic   acid   is   thus   bound, it   is   essentially immobilized  and  its  properties  as  a  mediator  and abillity to diffuse will be markedly affected.
