  • Patent number: 6999923
    Abstract: A system and method for detecting the presence of a particular source of audible content using an automatic speech recognizer component which is trained to recognize specific non-speech sounds. Training of the automatic speech recognizer component is accomplished by providing an appropriate model to be recognized and by tuning the automatic speech recognizer to the sounds created by the desired stimulus. The automatic speech recognizer can additionally be provided with processing means for distinguishing the desired stimulus from an irrelevant or unwanted stimulus which may have acoustic signatures with a high degree of similarity to that of the desired stimulus. The invention can be implemented in a portable detector to allow detection of a specific acoustic source at any location.

  • Patent number: 5627963
    Abstract: A cache memory architecture having a separate redundant read bus fully dedicated to redundancy and fed by a single spare sub-array common to all memory sub-arrays of the cache memory. Redundant sense amplifiers are dotted to the redundant read bus, and normal sense amplifiers are connected to a main read bus. Normal and redundant data are valid and available at the same time at the outputs of the normal and redundant sense amplifiers. When the late select address signals become valid, then the correct information can be selected via a multiplexer provided with an INHIBIT input. The multiplexer is normally controlled by decoded signals generated by a decoder, unless redundancy is required. If redundancy is required, the information generated by the bit address comparator forces the multiplexer, via the INHIBIT input, to select the redundant read bus, instead of one read bus of the main read bus, and to output the redundant byte as the selected one.
