Abstract: A voltage regulator for a charge pump includes a capacitor divider and a reset circuit. The capacitor divider produces, based on an input voltage (VPP), a sample voltage at a sampling node. The sampling node and a reference voltage VREF are connected to respective inputs of a comparator that generates an enable signal for the charge pump. The reset circuit connects to the divider and includes a first transistor connected between the sampling node and a biasing node. During a sampling mode, the reset circuit biases VDS of the first transistor to approximately zero at the regulation point to minimize sub-threshold IDS. During reset intervals, the reset circuit applies VREF to the biasing node. The reset circuit may include a second transistor connected between the biasing node and a known level (e.g., ground) and a biasing transistor connected between the biasing node and VREF.

Abstract: A telecommunications system utilizes a central database to determine characteristics for international calls, to facilitate call routing for international calls, or both. The central database includes termination information for telephone numbers in multiple nations outside the North American Numbering Plan. In one aspect, an interexchange switch receives a termination number for an international call from a local exchange carrier and uses information from the central database to help complete the call. In another aspect, the central database receives a telephone number from a remote user such as interexchange carrier (IXC) and, in response, transmits termination information to the remote user to identify whether the telephone number uses wireless termination. The remote user may then charge a customer for wireless termination, if appropriate, possibly even before the remote user receives an invoice that reflects wireless termination charges from a foreign wireless carrier.

Abstract: The present invention provides a method for distributing Internet Protocol Television (IPTV) content over a national IP backbone using GRE tunneling in a point-to-point ring topology. A logical path is defined that connects multiple hub offices, each including at least two routers, in a ring network topology. Generic Routing Encapsulation (GRE) tunnels are used over an existing Internet Protocol (IP) backbone to establish connectivity between adjacent hub offices. A direction for content flow is defined. The direction of flow may be determined by selecting a designated router. The routers of the hub offices selectively join to upstream routers. This direction may be reversed by changing the direction of in which routers join. IPTV content is distributed over the defined path using the GRE tunnels. The necessity of forwarding the content is determined at each hub office.

Abstract: A method and system for allowing users to control the operation of hyperlinks includes a graphical user interface that displays Internet and intranet hyperlinks from web sites. The graphical user interface includes a selectable button that accepts user settings. The user settings allow the users to determine the operation of the hyperlinks so that the hyperlinks either open in a new browser window or in an existing browser window when selected by the user. An interface engine generates the selectable button on the graphical user interface, examines the selectable button for any user settings, and controls the operation of the hyperlinks based upon the user settings.

Abstract: A system and method for designing a broadband tuner such that VCO pulling is minimized and gaps in frequency coverage are avoided, while total power consumption is reduced, is disclosed. A broadband spectrum is divided into sub-bands and various multipliers to a local oscillator output are introduced. In this fashion, the present invention allows a local oscillator within the broadband tuner to always generate signals that lie outside of the broadband spectrum for a particular broadband application. Additionally, a modulus ratio for a dual modulus prescaler with the local oscillator is maximized, thereby reducing power consumption.

Abstract: The invention provides a system and a method display incoming and outgoing call log data associated with telephone calls to and from a plurality of subscriber telephone numbers from one or more telephone networks. The system includes a switch in one network that receives a telephone call from the subscriber's telephone and launches a query in response to an AIN trigger to a service control point. In response, the service control point forwards associated call data to a call log gateway that translates the message into an asynchronous message containing call log data. The call log gateway forwards the asynchronous message to a unified communication platform where it is placed in subscriber mailbox and made available as a call log to a subscriber via a graphic user interface over the internet. A web server retrieves the call log and displays it to the subscriber at a web client.
