  • Patent number: 9057563
    Abstract: A heat exchange apparatus is provided with an indirect evaporative heat exchange section and a direct evaporative heat exchange section. The indirect evaporative heat exchange section is usually located above the direct evaporative heat exchange section, and an evaporative liquid is passed downwardly onto the indirect heat exchange section. The evaporative liquid that exits the indirect evaporative heat exchange section then passes downwardly across and through the direct heat exchange section. The evaporative liquid is collected in a sump and then pumped upwardly to be distributed again across the indirect heat exchange section. The indirect heat exchange section is comprised of a plate type heat exchanger.

  • Patent number: 9054666
    Abstract: A method for improving the performance of a noise cancellation device, the method includes determining whether one or more noise making objects (NMO) are near an audible range of the noise cancellation device and receiving a signal from the one or more NMOs indicative of a kind of noise the one or more NMOs is generating. The method also includes selecting a specific noise cancellation model to reduce an expected noise in response to the received kind of noise the one or more NMOs is generating.

  • Publication number: 20140209279
    Abstract: A heat exchange apparatus is provided with an indirect evaporative heat exchange section. An evaporative liquid is downwardly distributed onto the indirect section to indirectly exchange sensible heat with a hot fluid stream flowing within a series of enclosed circuits which comprise the indirect evaporative heat exchange section. An ideal flow rate for such evaporative liquid is between 2.5 and 3.5 gallons per minute per square foot of top surface area of the indirect heat exchange section.

  • Patent number: 7487084
    Abstract: A testing arrangement provided for speech recognition systems in vehicles. Preferably included are a “mobile client” secured in the vehicle and driven around at a desired speed, an audio system and speaker which plays back a set of prerecorded utterances stored digitally in a computer arrangement such that the speech of a human being is simulated, transmission of the speech signal to a server, followed by speech recognition and signal-to-noise ratio (SNR) computation. Here, the acceptability of the vehicular speech recognition system is preferably determined via comparison with pre-specified standards of recognition accuracy and SNR values.

  • Publication number: 20060229876
    Abstract: A method, apparatus and a computer program product to generate an audible speech word that corresponds to text. The method includes providing a text word and, in response to the text word, processing pre-recorded speech segments that are derived from a plurality of speakers to selectively concatenate together speech segments based on at least one cost function to form audio data for generating an audible speech word that corresponds to the text word. A data structure is also provided for use in a concatenative text-to-speech system that includes a plurality of speech segments derived from a plurality of speakers, where each speech segment includes an associated attribute vector each of which is comprised of at least one attribute vector element that identifies the speaker from which the speech segment was derived.

  • Publication number: 20050273338
    Abstract: Examples of paralinguistic events (e.g., breaths, coughs, sighs, etc.) are recorded. A text-to-speech (“TTS”) engine may insert the examples into a stream of synthetic speech using, for example, markup. The synthetic speech may include a combination of normal text and paralinguistic text.

  • Publication number: 20050234724
    Abstract: Disclosed is a system and method for improving the intelligibility of speech output by a speech synthesizer by determining if uncommon words exist in the text, and if it is determined that an uncommon word exists in the text, pausing the output of the synthesized speech of the uncommon word to offset the uncommon word from its surrounding speech.
