Abstract: Electronic stethoscopes may have various accessories, modular components, and various configurations for powering the various components and accessories of the electronic stethoscope. In one embodiment, an electronic stethoscope apparatus includes a microphone configured to generate an electrical signal in response to received sound from a living subject; amplification circuitry; a speaker operably coupled to the amplification circuitry to output the electric signal after amplification; and a power supply configured to power the amplification circuitry. Circuitry for advanced signal processing may also be included, such as noise cancelling circuitry. The electronic stethoscope may also include removable electronic modules for wired or wireless headphones, battery packs, lights, and/or an electronic device for implementing the percussive method.

Abstract: Mechanisms for generating a set of one or more elements of a fingerprint for a document, the document comprising a semantic construct having one or more ordered words, are provided. With these mechanisms, a range of sizes for a fingerprint element is defined and ordered words of the semantic construct are divided into a set of one or more mutually exclusive fingerprint elements. Each of the one or more mutually exclusive fingerprint elements includes a number of adjacent words, the number being within the range of sizes for a fingerprint element. Responsive to a determination that the set of mutually exclusive fingerprint elements excludes a word from the semantic construct, the excluded word is discarded.

Abstract: A method for generating a set of one or more elements of a fingerprint for a document, the document comprising a semantic construct having one or more ordered words, the method comprising the steps of: defining a range of sizes for a fingerprint element; dividing the ordered words of the semantic construct into a set of one or more mutually exclusive fingerprint elements, wherein each of the one or more mutually exclusive fingerprint elements includes a number of adjacent words, the number being within the range of sizes for a fingerprint element; and responsive to a determination that the set of mutually exclusive fingerprint elements excludes a word from the semantic construct, discarding the excluded word.
