  • Publication number: 20080006678
    Abstract: A friction stir tool is provided to perform friction stir riveting using a partially consumable pin, wherein the pin includes a cutting edge on a bottom surface thereof, wherein the tool is rotated at a first speed to enable cutting by the pin into a first material that is overlapping a second material, wherein after the pin has cut to a sufficient depth, the rotational speed of the tool is increased to thereby enable plasticization of the consumable pin, the first material, and the second material, wherein the tool is then rapidly decelerated until stopped, enabling diffusion bonding between the pin, the first material and the second material.

  • Patent number: 5847578
    Abstract: A programmable logic circuit includes a programmable logic array which generates a plurality of output signals for output from a single port on the programmable logic circuit, and which processes a plurality of input signals received from a single port on the programmable logic circuit. The programmable logic circuit also includes multiplexing means for receiving the plurality of output signals generated by the programmable logic array and for multiplexing the plurality of output signals. An output port outputs, from the programmable logic circuit, the multiplexed plurality of output signals generated by the programmable logic array. An input port receives a multiplexed plurality of input signals, and a demultiplexing means demultiplexes the multiplexed plurality of input signals and configurably communicates the demultiplexed plurality of input signals to the programmable logic array.

  • Patent number: 5761484
    Abstract: A compilation technique overcomes device pin limitations using virtual interconnections. Virtual interconnections overcome pin limitations by intelligently multiplexing each physical wire among multiple logical wires and pipelining these connections at the maximum clocking frequency. Virtual interconnections increase usable bandwidth and relax the absolute limits imposed on gate utilization in logic emulation systems employing Field Programmable Gate Arrays (FPGAs). A "softwire" compiler utilizes static routing and relies on minimal hardware support. The technique can be applied to any topology and FPGA device.
