Abstract: A system used by a technician for evaluating a Holter ECG tape having a signal representing a series of waveforms thereon and for generating a report reflecting the evaluation. A tape reader generates from the ECG tape an analog signal representative of the ECG waveforms recorded on the tape. An A/D converter converts the analog signal into a digital signal. A computer including a data bus, a memory, a processor controls the operation of the system. A display displays waveforms representing the ECG. A storage device is connected to the data bus. A direct memory access device moves the digital signals from the converter to the memory for storing the digital signal in the storage device. The converter provides at least a 12 bit a digital signal corresponding to the analog signal and includes means for converting the 12 bit digital signal to an 8 bit digital signal.

Abstract: Monopolar ECG signals are converted into the multichannel spectrum and autocorrelation domains, and different decision variables are identified from the autospectra. Statistically validated threshold levels are used for comparison with the decision variables to determine the probability of normal and ischemic conditions.

Abstract: A system and method for converting inoperative sentence elements into operative elements in which a set of grammar rules for substituting sentence elements with different elements is established. A sequential comparison between each grammar rule and the sentence elements is then accomplished to find a match between a grammar rule and one or more contiguous sentence elements. A substitution of the matched element for the different elements from the grammar rule is then accomplished. Such sequential comparison and substitution is continued for the entire series of sentence elements to fully convert the sentence to operative elements.

Abstract: A modular and portable system adapted to provide inventory control functions comprises a programmable master module including a display, a keypad, and processing electronics, and a scanning module for reading bar code symbols, where the master module is interconnectable with the scanning module to form a portable scanner for reading and analyzing bar code symbols, and the master module is adapted to interconnect to a plurality of other modules such as a printer module, an interface module, and a suitcase module.
