A computer system includes a plurality of interdependent processors. Each interdependent processor executes an independent operating system image without sharing file system state information, and each interdependent processor further has a network access card with a first network connection and a second network connection. The computer system has a first active backplane coupled to each first network connection of each processor; a second active backplane coupled to each second network connection of each processor, the second active backplane operating in lieu of the first active backplane in case of a fail-over; and one or more peripherals connected to each of the first and second active backplanes and responsive to data requests transmitted over the first and second active backplanes.

An interface for accessing data from one or more information systems using a wireless telephone or other user device. The interface is presented to a user as an abstraction of a unified mailbox and permits access by the user to messaging and other services from the wireless device. The interface is coupled to one or more converting modules to convert user inputs from the format in which they are received into a format that may be input to the desired information system.

A writing current circuit () supplies a controlled electrical current to a laser diode () for recording data swiftly onto a DVD (). A plurality of current sources () in the writing current circuit () supply electrical current directly to the laser diode (). Each current source () respectively receives a single output signal from a current control register () included in the writing current circuit () which activates or deactivates the current source () for supplying a particular quantity of current to the laser diode (). In one aspect, a pair of current reference signals received by the current source () control electrical current supply to the diode (). Incorporated into these controlling reference signals is a simulation of electrical characteristics of the diode (). In another aspect, each current source () responds to a logical inverse of the output signal from the current control register () for controlling overshoot in voltage applied across the diode ().

A method and apparatus for the evaluation and improvement of the mechanical and thermal properties of carbon-nanotube (CNT) and carbon nanofiber (CNF) arrays grown on a substrate is disclosed. The Young's modulus of a CNT/CNF material is measured by applying an axial compressive force on the CNT/CNF array and measuring the applied forces and the induced displacements. Also disclosed are the evaluation of the nonlinear stress-strain relationship of the CNT/CNF material, increasing of the Young's modulus and decreasing the thermal resistance by application of a compressive load, the application of rapid thermal annealing to improve the quality of the CNT/CNF material and to reduce the interfacial thermal resistance, improvement of the bonding strength of the CNT/CNF array to a substrate, evaluation of the bonding strength of the CNT/CNF array to a substrate, evaluation of the shearing force at failure, and an analytical stress model that enables one to predict the interfacial shearing stress from the measured force.
