Abstract: A novel three-step process for resolving a racemic spiro-hydantoin compound into its optical antipodes is disclosed, which involves (1) reacting said racemic compound with an optically-active asymmetric isocyanate of the formula RNCO, wherein R is (S)- or (R)-1-phenylethyl or (S)- or (R)-1-(1-naphthyl)ethyl, to form the corresponding diastereomeric ureido compound; (2) separating the resulting diastereomeric mixture into its component parts, and (3) thereafter converting the separated ureido diastereomers obtained in step (b) to the corresponding asymmetric hydantoin compounds by treatment with an alkali metal lower alkoxide (C1-C4), followed by acidification, whereupon the desired optical isomer is obtained. The final products so obtained, such as (4S)-(+)-6-fluoro-2,3-dihydro-spiro[4H-1-benzopyran-4,4 min -imidazoli dine]-2 min ,5 min -dione (sorbinil) and (5 min S)-3 min -chloro-5 min ,6 min ,7 min ,8 min -tetrahydro-spiro[i midazolidine-4,5 min -quinoline]-2,5-dione, are known to be useful in preventing or alleviating certain chronic diabetic complications. The aforementioned diastereomeric ureido intermediates are novel compounds.

Abstract: A speech recognition system includes a parameter extracting section (10) for extracting a speech parameter of input speech, a first recognizing section (20) for performing recognition processing by word-based matching, and a second recognizing section (30) for performing word recognition by matching in units of word constituent elements. The first word recognizing section segments (20, 30) the speech parameter in units of words to extract a word speech pattern and performs word recognition by matching the word speech pattern with a predetermined word reference pattern. The second word recognizing section (20, 30) performs recognition in units of word constituent elements by using the extracted speech parameter and performs word recognition on the basis of candidates of an obtained word constituent element series. The speech recognition system further includes a recognition result output section (40) for totally obtaining a recognition result on the basis of the word recognition results obtained by the first and second recognizing sections (20, 30) and outputting the obtained recognition result. The speech recognition system further includes a word reference pattern learning section (50) for performing learning of a word reference pattern on the basis of the recognition result obtained by the recognizing result output section (40) and the word speech pattern.

Abstract: A personnel monitoring system includes a tag (60) worn by each monitored person. The tag repeatedly emits digital radio signals, and a predetermined bit in the signal changes with time according to a predetermined pattern. Monitoring apparatus (12) detects the radio signals and sends an absence alarm signal if the signals cease. The monitoring apparatus detects spurious, forged signals which do not replicate the predetermined pattern of variation and provides a forgery alarm signal. The tag may be attached to the person by a strap bearing parallel electrical conductors. Attempts to remove the tag by severing the strap cause electrical contact between the conductors. Such contact triggers a detector, which in turn alters the radio signal.

Abstract: A transmitter for converting a binary digital signal into a pseudo-ternary signal at first and second output nodes (40, 41) to form differential output voltages includes a current source amplifier circuit (10), a first voltage source amplifier circuit (12), and a second voltage source amplifier circuit (14). The current source amplifier circuit (10) is responsive to a reference current for generating a first drive current and a second drive current. The first voltage source amplifier circuit (12) is responsive to a reference voltage, a first digital control signal, a second digital control signal and the first drive current for driving the first output node (40) to the reference voltage when the second digital control signal is at a high logic level and for driving the first output node (40) to a ground potential when the first digital control signal is at a high logic level. The second voltage source amplifier circuit (14) is responsive to the reference voltage, first digital control signal, second digital control signal, and sec and drive current for driving the second output node (41) to the reference voltage when the first digital control signal is at a high logic level and for driving the second output mace (41) to the ground potential when the second digital control signal is at a high logic level. The transmitter has been designed so as to overcome the problem of line clamping during a power-dawn condition, provides a current limiting function, and reduces the ringing problem associated with driving an inductive load with a high impedance source.
