  • Patent number: 8412877
    Abstract: A method is provided for managing errors in a virtualized information handling system that includes an error detection system and a hypervisor allowing multiple virtual machines to run on the information handling system. The hypervisor may assign at least one memory region to each of multiple virtual machines. The error detection system may detect an error, determine a physical memory address associated with the error, and report that address to the hypervisor. Additionally, the hypervisor may determine whether the memory region assigned to each virtual machine includes the physical memory address associated with the error. The hypervisor may shut down each virtual machine for which a memory region assigned to that virtual machine includes the physical memory address associated with the error, and not shut down each virtual machine for which the memory regions assigned to that virtual machine do not include the physical memory address associated with the error.

  • Publication number: 20090095660
    Abstract: A process is described for the separation of fluorinated plastic particles from a mixture of solid particles of similar specific gravity. The process comprises mixing the particles with water, adding air to create bubbles, and generating two or more product streams, one of which floats and the other which sinks. The floating stream is enriched in fluoropolymer particles. Per pass yield and selectivity of fluorinated plastics are enhanced by the addition of a carboxylic acid to the froth flotation medium.

  • Publication number: 20090065404
    Abstract: A process for the separation of a multiple domain solid feedstock such as that derived from ASR, WSR, and/or ESR is disclosed which comprises granulating the feedstock to produce particles each of substantially a single domain, with each type of particle having a different density. The particles are introduced into a suitable aqueous salt solution. Aqueous salt solutions containing cations comprising sodium, calcium and ammonium, and anions comprising nitrate, bromide, and chloride are useful. A dispersion mixer having a high shear and/or turbulent zone is utilized to disperse agglomerated particles and a quiescent hydrogravity tank is utilized to effect binary separation of the mixture of particles into a stream with a higher average specific gravity, and a stream with a lower average specific gravity. A higher degree of product purity can be obtained by subjecting either of the product streams from the first hydrogravity stage to additional stages of hydrogravity separation.

  • Publication number: 20050173310
    Abstract: The hydrogravity separation of a multiple component solid feedstock comprises granulating the feedstock to produce particles substantially of individual components having different densities. A dispersion mixer having a high shear and/or turbulent zone is utilized to disperse agglomerated particles and a quiescent hydrogravity tank is utilized to effect binary separation of one or more of the heaviest or one or more of the lightest feedstock components by utilizing an aqueous solution having a specific gravity intermediate of the various components. A high degree of purity is obtained by feeding particles of a selected component to a plurality of sequential dispersion mixers and hydrogravity separation tanks. In a similar manner, remaining thermoplastic particle components can be selectively removed and purified.

    Abstract: In a preferred embodiment, the invention provides a fiber optic pressure sensor apparatus which includes a light source, a reflective sensor diaphragm movable in accordance with pressure in a medium and an optical fiber coupled to the light source for delivering a first wavefront of light to the reflective sensor diaphragm. The optical fiber has an endface which is separated from the reflective sensor diaphragm by a gap, the endface receiving a second wavefront of light reflected from the reflective sensor diaphragm. The first and second wavefronts constructively and destructively interfere to create a modulated optical signal. A spectrometer is coupled to the optical fiber for converting the optical signal into a series of digital values, and means for analyzing the digital values is provided for obtaining a measurement of the pressure in the medium. An optical coupler is preferably provided for coupling the light source, the optical fiber, and the spectrometer.

  • Patent number: 6756781
    Abstract: Described are improved transmissive magneto-optical sensors that may be used to determine the magnitude and phase of a magnetic field surrounding a conductor, and when in contact with the conductor, the surface temperature of the conductor. The magneto-optical sensor may be made to be symmetric around the direction of propagation of the internal light, enabling ease of manufacturing as well as automated assembly and calibration. The magneto-optical sensor may also be made to be symmetric about the plane determined by the Faraday rotator material, thus enabling reciprocating optical paths for increased vibration and birefringence immunity. The disclosed sensors preferably include cylindrically symmetrical components, thereby making the sensor readily mass-producible.
