Abstract: Abstract of the Disclosure An automated sample analysis  instrument positively identifies and maintains the identity of a plurality of patient samples  contained  in  individual  sample  containers.    The invention prevents sample misidentification,  especially when patient sample must be transferred from one sample container to reaction wells in Microtiter? plates.  Rows of reaction wells in Microtiter? plates are processed in parallel so the differ-ence in reaction time between any two wells on a plate is four minutes or less.  Reaction wells are washed with high-pressure jets of wash solution and are aspirated so as to advantageously utilize fluid meniscus on top of fluid contained in the wells. The apparatus can be adjusted to perform a variety of different ELISA-type tests.

The application of bonding agent is performed using at least one applying roller pair (102, 104) in which one or more rollers is corrugated to thereby allow better infiltration of the agent.  Squeeze rollers (118) advantageously remove excess bonding agent.  The applying rollers are preferably disposed in a bath (126) and the bonding agent, for example a foam, may be applied in the bath to be carried upstream by the rotation of the applying rollers.

Title: Word annotation system
Inventor: KUCERA HENRY
IPC: G06F17/27
Filed: 1988-10-07
Granted: 1992-05-05
Abstract: Abstract A system for annotating digitally encoded text includes a dictionary of base forms.  For each base form, a first set of tags represents possible grammatical and syntactic properties of the word, and may encode inflectional paradigms of the base form, or feature agreement behavior and special processing.  If a text word is not found in the dictionary, an inflectional analyzer looks up one or more base forms derived from the word, and if found, and annotates them with their dictionary tags.  A morphological analyzer assigns tags to words not retrieved in the dictionary.  The morphological analyzer recognizes words formed by prefixation and suffixation, as well as proper nouns, ordinals, idiomatic expressions, and certain classes of character strings.  The tagged words of a sentence are then processed to parse the sentence.

The distance along the direction of propagation between the central axes is varied in the direction substantially normal to the direction of propagation. The surface elastic wave filter may include an electric conductor disposed on the piezoelectric substrate between the input and output electrodes and having a dimension in the direction of propagation, the dimension being varied in the direction substantially normal to the direction of propagation. A medium for varying the speed of propagation of the surface elastic wave may be positioned in place of the electric conductor.

Abstract: A data communication equipment equalizer which minimizes the total training time delay (RTS-CTS) is disclosed. The total RTS-CTS delay of the provided equalizer consists of a delay due to a minimal training sequence required for the equalizer coefficients to converge given a low distortion channel, plus whatever delay is necessary for the equalizer coefficients to converge given theparticular channel. The equalizer of the invention preferably comprises: first and second FIRs each having a plurality of taps for storing data signal samples overtime, a plurality of tap gain means for multiplying the equalizer coefficients with the stored data samples, a coefficient update for comparing the sum of the tap gain means products to an ideal value and for changing said equalizer coefficients accordingly, and processing means for processing the communications data according to the adapted equalizer coefficients; a buffer delay means for receiving and storing the communications data transmitted after the completion of the training sequence and before the equalizer coefficients have been sufficiently adapted to allow substantially error free transmission; and a data decision means for deciding what ideal data value to assign a processed data sample. While the training sequence length is minimized for an optimal channel, no communications data is lost in a non-optimal channel as the buffer delay means stores the communications data while the FIRs use the communication data to continue to adapt the equalizer coefficients.
