    Abstract: Systems and methods of increasing power converter efficiency are provided. A power converter includes a boost circuit configured to receive a DC input voltage ranging from a minimum input voltage value to a maximum voltage value, boost the DC input voltage to a predefined nominal voltage value when the DC input voltage has a value between the minimum input voltage value and the predefined nominal voltage value, and maintain the DC input voltage when the DC input voltage has a value that is greater than or equal to the predefined nominal voltage value and less than the maximum input voltage value. The unit also includes a DC-DC converter coupled to an output of the boost circuit, the DC-DC converter configured to convert the boosted DC voltage or the maintained DC voltage to a DC output voltage.

  • Patent number: 7886256
    Abstract: Approaches for determining a static timing analysis of a logic design are disclosed. Physical delay arcs of a plurality of physical elements of an integrated circuit specify respective propagation delays from inputs of the physical elements to outputs of the physical elements. Logic components of the logic design are mapped to selected ones of the physical components of the physical elements. For each of the logic components, the logic delay arcs are determined from the physical delay arcs. Each logic delay arc for each logic component specifies a propagation delay from an input of the logic component to an output of the logic component. A static timing analysis of the logic components is performed using the logic delay arc, and data from the timing analysis is output.

  • Patent number: 7523163
    Abstract: A distributed collaborative computer system is provided that comprises a plurality of server computers interconnected via a high-speed link. Client computers can connect to any available server computer and start or join a conference hosted on either the server computer to which the client computer is connected or any other server in the system. As a result, the system and method of the present invention is easily scalable to support an arbitrary number of participants to a conference by merely adding the appropriate number of server computers to the system. In addition, by replicating the conference information on more than one server computer, the single point of failure limitation is eliminated. In fact, if a server hosting or participating in a conference malfunctions, the failure is detected by other server computers and the client computer is able to reconnect to the conference through a new server computer.
