  • Patent number: 8892791
    Abstract: An apparatus and method for synchronous communications using a serial data stream employs a housing with a controller and a back plane. The housing accepts one or more modules for interconnection with the back plane. The back plane distributes power to the modules and provides a communication link from the controller to each module. Each communication link includes a data out line, a data in line and a clock line, where each clock line is derived from one clock source.
    Type: Grant

  • Patent number: 8037327
    Abstract: A system for improving dynamic response in a power supply includes a mainframe module having a memory and a mainframe microprocessor, the mainframe processor configured to calculate a plurality of tables in which each table represents a current/voltage (I/V) characteristic curve for the power supply, at least two power supply modules coupled to the mainframe module, each power supply module having a random access memory element, the random access memory element configured to receive and store a first table and a second table, wherein the mainframe microprocessor transfers the first table to each power supply module, and wherein each power supply module executes a respective first table while the mainframe processor calculates the second table for each power supply module and while the mainframe processor transfers the second table to each power supply module.
