  • Fly ash treatment by in situ ozone generation employing a venturi
    Patent number: 7416646
    Abstract: Disclosed is a method of treating, fly ash having an unacceptably high concentration of carbon, with ozone produced in situ by corona discharge. This method will allow high carbon-content fly ash to be used with air entrainment agents as an additive to cement. The corona discharge can be produced in the exhaust pipe with a venturi of various combustion systems. The device of this invention can be used in conjunction with a triboelectric carbon-fly ash separation system or in a conventional combustion system. The corona discharge is produced off of sharp-tipped metal devices. A venturi is used in the exhaust pipe in the exhaust pipe in conjunction with the sharp-tipped metal devices.

  • High performance RISC instruction set digital signal processor having circular buffer and looping controls
    Patent number: 7401205
    Abstract: A DSP superscalar architecture employing dual multiply accumulate pipelines. Dual MAC pipelines allow for a seem less transition between established RISC instruction sets and extended DSP instructions sets. Relocatable opcodes are provide to allow further extensions of RISC instruction sets. The DSP superscalar architecture also provides memory pointers with hardware circular buffer support, an interruptible and nested zero-overhead loop counter, and prioritized low-overhead interrupts.
