  • Patent number: 9642385
    Abstract: Various embodiments of processing systems and components for sterilization or pasteurization and associated methods of operation are described herein. For example, a method of sterilization or pasteurization includes immersing an item in an immersion fluid, and the immersed item is subject to a hydrostatic pressure of the immersion fluid. The method also includes applying microwave energy to the item while the item is immersed in the immersion fluid and subject to the hydrostatic pressure of the immersion fluid. The hydrostatic pressure of the immersion fluid prevents the water content of the item from causing steam explosion in the item while the microwave energy is applied. The method further includes heating the item immersed in the immersion fluid to a target temperature with the applied microwave energy, the target temperature being sufficient to achieve sterilization or pasteurization of the item.

  • Patent number: 9589719
    Abstract: Technologies are generally described for switchable patterned metal shield inductance structures. In some examples, an inductance structure on a substrate may include an inductor and a metal shield, where the metal shield separates and shields the inductor from the substrate. The configuration of the metal shield and the inductor may facilitate reduction in the overall inductance of the inductance structure. In particular, the metal shield may be configured to develop one or more eddy currents in response to an inductor-generated magnetic field. The eddy currents may then result in a magnetic field opposing the inductor-generated magnetic field, which may result in a reduction in the overall magnetic field and the overall inductance of the inductance structure. The metal shield may be switchable between multiple modes, where each mode may be effective to reduce the overall inductance by a different amount.

  • Patent number: 9567611
    Abstract: Low cost, efficient two-stage anaerobic digestion systems for the production of biogas (e.g. methane) are provided. During the first stage, biogas is produced in a first reactor by anaerobic microbes cultured in two phases: a high solids phase and a low solids phase. During the second stage, biogas is produced in a second reactor by a methanogen-rich anaerobic culture cultured in low solids medium. Removal of effluent comprising pH lowering reaction products assists in maintaining a suitable pH in the high solids phase. The transfer of effluent from the second reactor to the first reactor assists in maintaining a suitable pH in the high solids phase, in mixing of the high solids phase, and in reseeding the high solids phase with methanogens. Methane is produced in and recovered from both reactors.

  • Patent number: 9554512
    Abstract: Robotic systems and specialized end-effectors provide for automated harvesting of produce such as fresh market apples. An underactuated design using tendons and flexure joints with passive compliance increases robustness to position error, overcoming a significant limitation of previous fruit harvesting end-effectors. Some devices use open-loop control, provide a shape-adaptive grasp, and produce contact forces similar to those used during optimal hand picking patterns. Other benefits include relatively low weight, low cost, and simplicity.

  • Patent number: 9539359
    Abstract: Mesoporous calcium silicate compositions for controlled release of bioactive agents and methods for producing such compositions are disclosed herein. In one embodiment, mesoporous calcium silicate is synthesized by acid modification of wollastonite particles using hydrochloric acid. A hydrated silica gel layer having abundant Si—OH functional groups can be formed on the surface of wollastonite after acid modification. Bruhauer-Emmett-Teller (BET) surface area increased significantly due to acid modification and, in one arrangement, reached over 350 m2/g. Acid modified mesoporous calcium silicate compositions show a higher ability to adsorb protein compared to unmodified particles and demonstrate controlled release kinetics of these proteins.

  • Publication number: 20160377423
    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.
