  • Patent number: 10190067
    Abstract: A novel hydraulic (e.g., a biohydraulic) fluid which has high performance attributes is disclosed herein. Such a novel hydraulic fluid includes a contribution of a range of 10% up to about 85% by weight of at least one of: natural esters, synthetic esters, polyols, a vegetable oil, 1% up to about 40% by weight of polyalphaolefin (PAO), 1% up to about 40% by weight of polyalkylene glycol (PAG), and mixtures thereof, and wherein up to about 10% by weight quantity of one or more additives are introduced to provide desired properties that include at least one of: a high viscosity index, a low pour point, a hydrolytic stability, and an oxidative stability, as part of the hydraulic fluid contribution.
    Type: Grant
    Filed: February 24, 2017
    Date of Patent: January 29, 2019
    Assignee: Washington State University
    Inventors: Ray Gunawidjaja, Pranav Nawani, Hergen Eilers
  • Patent number: 9762565
    Abstract: Unique methods and systems are introduced herein for the determination of unique spatial light modulator based optical signatures of intrinsic and extrinsic scattering surface markers. These techniques can be used to authenticate semiconductor components and systems at various stages during the manufacturing process by measuring and cross correlating the surface marker's unique optical signature. In addition, these techniques can be used with extrinsic surface markers which are added to existing hardware (e.g. containers, locks, doors, etc.). These markers can then be measured for their unique optical signatures, which can be stored and used at a later time for cross-correlation to authenticate the surface marker and verify the hardware's provenance.
