  • Publication number: 20080080385
    Abstract: Systems and methods for analyzing communication sessions using fragments are provided. In this regard, a representative method includes: delineating fragments of an audio component of a communication session, each of the fragments being attributable to a party of the communication session and representing a contiguous period of time during which that party was speaking; and automatically assessing quality of at least some of the fragments such that a quality assessment of the communication session is determined.

  • Publication number: 20080082341
    Abstract: A speech analyzer is integrated or otherwise coupled to an audio player. The speech analyzer is used to identify recorded communication sessions in accordance with a search criterion. A search criterion may be spoken or otherwise communicated to the speech analyzer. Results generated by the speech analyzer are converted into visual information that is presented to a user of the speech analyzer. Results generated by the speech analyzer can be cached for real-time user review while the speech analyzer processes additional stored conversations.

  • Patent number: 7342227
    Abstract: A plasma sprayed TiO2 coating is used to remove effluents produced during an electrical charging step using a corona charging device. The plasma spray allows for the application of TiO2 ceramic to an aluminum dicorotron housing. Plasma spray also increases the electrical conductivity of the TiO2 (which is necessary for the dicorotron operation). Plasma sprayed coatings are also porous which aids in the capture and reduction of effluents.

  • Publication number: 20070297578
    Abstract: Systems and methods for recording communications are provided. In this regard, a representative system incorporates recording resources and a recording controller. The recording resources are operative to record information corresponding to communications, with the communications being provided in multiple communication formats and/or involving devices and paths with varying characteristics and capabilities. The recording controller is communicatively coupled to each of the recording resources. The recording controller is operative to: monitor the communications; determine suitability and availability of the recording resources for recording the communications; analyze a recording hierarchy; and allocate at least an available one of the recording resources for recording a designated one of the communications based on the suitability and availability determined and the recording hierarchy.

  • Patent number: 7178780
    Abstract: A mold used to form a magnetic member includes a mold body having a mold opening, a mold support that supports the mold cavity, and a mold insert. The mold insert is disposed in the mold opening of the mold body to form a mold cavity. The mold insert is coated with a coating to protect the mold body from chemical attack and abrasive wear of the mold material. The coating comprises an electroless nickel layer formed on or over the mold insert, and a chromium nitride layer formed on or over the electroless nickel layer. The mold insert can be formed of beryllium-copper (Be—Cu).

  • Patent number: 5432798
    Abstract: A method of multipoint communications utilizes a protocol in which data messages (10) sent by a primary source are multicast to a plurality of secondary receiving stations (S.sub.1 . . . S.sub.n). Each message packet contains a control field comprising a station identifier code (14) and an instruction for the specified station to acknowledge a predetermined number of messages. Each successive message packet comprises a station identifier code which differs in an alterable set cyclical sequence. Thus, acknowledgements of correct receipt of data are taken in a cycle of length L such that in a space of L messages each receiver must acknowledge at least once. In this way the primary source need only keep the L latest messages because all the stations have acknowledged correct receipt of at least up to the current message minus L. The multipoint communications method uses a protocol which can be applied to existing communications networks.
