  • Patent number: 5226141
    Abstract: A variable length cache system keeps track of the amount of available space on an output device. The capacity of the cache system is continuously increased so long as it is less than the available output space on the output unit. Once the size of the cache system exceeds the available output space on the output unit, which is less than the total space available on the output unit by a predetermined amount, the contents of the cache memory are flushed or written to the output device and the size of the cache memory is reduced to zero.

  • Patent number: 5226129
    Abstract: A processor capable of processing a variable word length instruction has a program counter controlled to indicate the head of an instruction by the value of the program counter. There are provided an adder for summing the length of decoded portions in the variable word length instruction in accordance with the progress of the instruction decoding, and another adder for adding the length of the decoded instruction portions to the program counter so as to update the program counter. Further, there is provided a circuit for calculating an operand effective address by using the value of the program counter in the course of the variable word length instruction decoding. Thus, the updating of the program counter and the generation of the effective address are concurrently executed.

  • Patent number: 5224206
    Abstract: A case-based retrieval system and method for using same for retrieving justifiably relevant cases from a case library in which past problem solving experiences (cases) are stored. The system obtains the symptoms of a new problem. A set of cases are initially retrieved from the case library based on the symptoms of the new problem. It is then determined for each initially retrieved case using a casual explanation for the case whether the case is justifiably relevant to the new problem, with only justifiably relevant cases being returned to the user of the system.

  • Patent number: 5222220
    Abstract: The present invention is a method for a microprocessor such that when a call is made to a subroutine or an interrupt, a return address is stored in a "stack" memory (RAM) and also that a particular piece of hardware write the return address to an additional register (latches) within the microprocessor. The method enables a comparison to be made at the end of the subroutine or interrupt such that the address to which the subroutine tries to return is compared to the address as latched into the hardware portion of the microprocessor to detect whether any human error has occurred in the programming of the interrupt program or the subroutine.

  • Patent number: 5222197
    Abstract: A rule invocation mechanism in an inductive learning engine employing symbolic rules for characterizing a sequence of time-related events. The rules to be tested as hypotheses against new events in the sequence are ranked according to their information content or "quality" value. The efficiency of the rule-to-event pattern matching process for characterizing the new events is increased by not testing a hypothesis if a much better hypothesis already exists. Those hypotheses that characterize events in the sequence are tagged to the event.

  • Patent number: 5222188
    Abstract: In a digital computer, there is provided a method of recognizing speech, comprising the steps of: entering a cohesive speech segment; determining gross acoustic attributes of the entered segment; determining fine acoustic attributes of the entered segment; assigning at least one subsyllable to the entered segment based on the gross and fine acoustic attributes determined; repeating the foregoing steps on successive cohesive speech segments to generate at least one sequence of subsyllables; converting the sequence of subsyllables into a sequence of syllables by finding the sequence of subsyllables in a table in which predetermined subsyllable sequences correspond with respective syllables and syllable sequences; combining the converted sequence of syllables into words; and verifying the conformance of the words to a first predetermined set of grammatical rules. An apparatus implementing the method is also disclosed.

  • Patent number: 5222193
    Abstract: A means and method for training an electronic network of analog cells. A generic universal programmer interface (GUPI) is provided to enable connection of an adaptor to a host computer via a personal computer personal programmer (PCPP) for training an ETANN chip. An opening in the top of the GUPI provides for installation of the adaptor. The adaptor of the present invention plugs into the GUPI module to provide for connecting either an ETANN chip or a Confidence Test Module (CTM) for access by the user via the host computer. A target socket located on the top surface of the adaptor allows the user to physically connect the ETANN chip or the CTM to adapter of the present invention.

  • Patent number: 5222231
    Abstract: A data processing method and apparatus have a resume function and use a password. When a power switch of a data processing system is turned on while it is selected that the resume function is to be enabled and the password is to be collated, the data processing system displays a message prompting an operator to input a password. When a predetermined password is input from a keyboard or the like, the data processing system executes resume processing, i.e., executes data processing to be continued to data processing executed immediately before the power switch was turned off. When the predetermined password is not input, the resume operation is inhibited, and a content saved by the resume function can be prevented from being disclosed to or destroyed by a third party.

  • Patent number: 5222187
    Abstract: A speech system recognizes words from a spoken phrase that conform to checksum constraints. Grammar rules are applied to hypothesize words according to the checksum constraints. The checksum associated with the phrase is thus inherent in the grammar. Sentences which do not meet a predetermined checksum constraint are not valid under the grammar rules and are therefore inherently rejected. The checksum constraints result in increased recognition accuracy.

  • Patent number: 5220640
    Abstract: A neural net architecture provides for the recognition of an input signal which is a rate variant of a learned signal pattern, reducing the neural net training requirements. The duration of a digital sampling of the input signal is scaled by a time-scaling network, creating a multiplicity of scaled signals which are then compared to memorized signal patterns contained in a self-organizing feature map. The feature map outputs values which indicate how well the scaled input signals match various learned signal patterns. A comparator determines which one of the values is greatest, thus indicating a best match between the input signal and one of the learned signal patterns.
