  • Patent number: 7372949
    Abstract: Disclosed are systems and methods in which call intelligence, such as may be disposed in communication with signaling systems utilized in controlling calls, is used to provide information for making determinations with respect to the treatment of calls. Call intelligence may be coupled to or disposed within such networks to receive signaling therefrom and/or transmit signaling thereto for determining the appropriate treatment of a call and, preferably, controlling the treatment of a call in accordance with such determination. Signaling messages received by call intelligence may be utilized to determine that a particular calling activity (e.g., enhanced calling service such as call redirecting or three-way calling) is being employed, to collect data with respect to a call, and the like.

  • Publication number: 20080108198
    Abstract: Enhancement mode, field effect transistors wherein at least a portion of the transistor structure may be substantially transparent. One variant of the transistor includes a channel layer comprising a substantially insulating, substantially transparent, material selected from ZnO, SnO2, or In2O3. A gate insulator layer comprising a substantially transparent material is located adjacent to the channel layer so as to define a channel layer/gate insulator layer interface. A second variant of the transistor includes a channel layer comprising a substantially transparent material selected from substantially insulating ZnO, SnO2 or In2O3, the substantially insulating ZnO, SnO2, or In2O3 being produced by annealing. Devices that include the transistors and methods for making the transistors are also disclosed.
