Abstract: A control circuit operably couples to a plurality of network interfaces and receives, at least substantially in near real time, Internet Protocol (IP) flow content from a plurality of mobile communications (comprising at least voice communications). The control circuit analyzes that IP flow content to identify at least one mobile communications infrastructure cell that is underperforming with respect to voice quality and further identifies at least one cause for underperformance by that mobile communications infrastructure cell. The control circuit then enables voice optimization for that mobile communications infrastructure cell.

Abstract: The backflow valve of the present invention includes a valve housing having a cavity therein with an inlet and an outlet to the valve cavity. A switch is in communication with the valve cavity and is moveable from an off position to an on position in response to liquid filling the valve cavity. A valve is moveable in response to the movement of the switch to the on position. The valve moves to a closed position shutting off the fluid flow through the backflow valve.

Abstract: A method and apparatus is provided for automatically completing a directory assisted call connection from within a cellular system. The method includes the steps of requesting a telephone number of a communication target by a cellular communication unit from directory assistance and voice recognizing each digit of an audio representation of the telephone number of the communication target returned by directory assistance. The method further includes the step of completing the call connection from the cellular communication unit to the communication target based upon the voice recognized returned number.

Abstract: A sewer back flow valve having sensing means located at the top of the sewer line and an inflatable annular bladder responsive to a sensing means to permit passage of sewage through the annular bladder under normal water level conditions and operable to prevent back flow of sewage through the annular bladder under high water level conditions.
