    摘要: A PRI (pulse repetition interval) autocorrelator that functions as a data analyzer for recognition of PRIs in a data set composed of time ordered TOA (time of arrival)) words representing the time of reception of a plurality of pulses from a plurality of emitters. The processing of a data set is performed at each of a plurality of cells of a plurality of coarse map intervals or octaves by adding an incremental assumed periodicity .tau. to the time of arrival and performing an autocorrelation comparison of the data set for each cell to provide correlation counts. An amplitude ordered list is then formed of the cell correlation counts which are greater than a threshold and subcells of each cell on the list are subject to a fine level autocorrelation for determining the PRI.

    摘要: 1,179,029. Speech recognition. INTERNATIONAL BUSINESS MACHINES CORP. 19 April, 1967 [2 May, 1966], No. 17934/67. Heading G4R. Speech . recognition, apparatus determines characteristics of successive pulse periods of a speech signal, accumulates the levels of correspondence between these characteristics and stored characteristics compared with them, and indicates when the accumulation exceeds a predetermined value after the comparison of a predetermined number of characteristics. The identity of a person is verified by comparing characteristics of a particular spoken word (or words) with stored characteristics of the word as spoken by the true person. The characteristics used are the voltage and time of occurrence of the first 3 peaks and 2 troughs of each of a series of pulse periods of the speech, a pulse period being a period of the voiced component of the speech. The voltage characteristics are all positive by choice of the zero of voltage. The characteristics mentioned for representative pulse periods of the word as spoken by the true person are retrieved from a back-up store .and placed in a closed-loop shift register. After detection of the beginning of .a pulse period in the input speech (i.e. that from the person, whose identity is to be verified), detection of the first peak causes the stored voltage and time characteristics for the first peak in each of three adjacent pulse period sections of the shift register to be subtracted from the actual voltage value of the input first peak (converted to digital form) and the time (specified by a clock-driven time counter) respectively, the six subtractions being accomplished by adders since the characteristics are stored in the shift register in negative form. The differences are squared and added into respective ones of three accumulators (via preliminary adders), one accumulator corresponding to each of the three shift register sections used. The next two troughs and two peaks are treated similarly, the shift register being shifted to bring the stored characteristics for these troughs and peaks into position for use, and the squared differences being added into the same accumulators. After the total of five troughs and peaks, a second counter causes the contents of the accumulator holding the smallest value, representing the difference between the input pulse period and the most similar of the three stored pulse periods used, to be gated to a sum accumulator, and also causes the shift register to be so shifted that the centre one of the three stored pulse periods which will be compared with the next input pulse period will be the most similar stored pulse period just determined. The above operations are repeated for each of the following input pulse periods, the sum accumulator accumulating a measure of the total deviation so far between the input and stored characteristics. The time counter, second counter and the accumulators (except the sum accumulator) are reset for each pulse period. After each pulse period, the second counter also gates the contents of the sum accumulator to a divider to be divided by the number of pulse periods which have so far occurred, as specified by a third counter. The quotient is compared with a threshold and if it exceeds it, a "stop non-verify" signal is produced which indicates the identity is false and stops operations. The totality of characteristics in the shift register is followed by a special mark and when all the stored characteristics have been used this is detected in a particular stage of the register and produces an "identity verified" signal if the "stop non- verify" signal is absent. The stored characteristics could be in analogue form and analogue circuitry be used. The input speech could be compared with a plurality of stored sets of characteristics, each set as above, to identify the speaker.

    摘要: A digital rate monitor including a microprocessor operating under program control to receive and process event pulses to calculate the rate of the event pulses, and display the calculated rate. The rate is calculated by accumulating a batch of pulses and measuring the time it takes to accumulate such number of pulses. The batch size for a given calculation is a function of the event pulse rate, and a different batch size is automatically selected if the event pulse rate increases or decreases within a certain range. The rate is calculated once per second by averaging sixteen pulses for high speed inputs, four pulses for intermediate rates, and using a single pulse for low speed inputs.

    摘要: A pulse height counter for counting the number of excursions of an incoming analog signal through each of a plurality of amplitude ranges. The pulse height counter automatically records not only the number of excursions through each amplitude level, but also records the number of amplitude excursions for each of a plurality of intervals. An analog input signal to be analyzed is synchronously applied to each of a plurality of comparators (VCO - VCF), which have reference voltages that are related so as to define predetermined amplitude ranges. During a count cycle, a counting circuit (CO - CF) receives the output signals from each of the comparators and produces a set of count data that indicates the number of occurrences of the analog input signal within each of the amplitude ranges. The count cycle is followed by a write cycle, during which the count values are stored in separate data bins, or event memories (MO - MF). The addresses of the memories are related to separate intervals during which count data for individual input signals can be stored. The addresses are shared by the memories so that, for a given interval, the count data for each of the amplitude ranges are stored at the same address but in a separate one of the memories. Thus, the count data for each of the amplitude ranges recorded during a predetermined interval may be recalled and displayed (18, 20, 22) during a readout mode of operation. The timing of the counting and writing cycles of operation is controlled by a count timer (32), a write timer (34), and an address counter (38) included in a timing and control circuit (10). Upon receipt of the analog input signal, the count timer is triggered to enable transfer of the outputs of the comparators to the counters. At the conclusion of the count cycle, the comparator outputs are disabled and the memories are enabled so that the count data may be transferred thereto. At the conclusion of the write cycle, the memories are disabled from receiving further count data and the counters are automatically reset so that new count data can be created upon receipt of a subsequent input signal. Substantially simultaneously with the resetting of the counters, the commonly shared address is incremented by 1 so that the count data for the next-received input signal is stored in the respective memories at the next successive storage location.

    摘要: A portable data recorder for recording time-related information on tape cassettes. The recorder includes a briefcase shell in which the other components are mounted, a keyboard having a plurality of keys each of which, when depressed, produces a signal, and a plurality of key lines each coupled to a different one of the keys for carrying the signals produced thereby. A multiplexer, under control of a microprocessor, sequentially samples the key lines and transfers to the microprocessor any signals present on the key lines. The microprocessor then records on a cassette recorder data indicating whether or not a signal was present on each of the key lines sampled, and the time of sampling the key lines. The multiplexer successively samples the plurality of key lines so that both the identity of the keys depressed and the time duration of depression of the keys are recorded.
