  • Patent number: 11014359
    Abstract: A system and apparatus includes a nozzle formed on a first surface of a substrate, and a fluid passage in the substrate and fluidically connected to the nozzle, the fluid passage being nonlinear along at least a portion of its length and having a cross section that varies along its length, wherein the fluid passage has a width near a second surface of the substrate that is different from a width near a bottom of the fluid passage. A system and apparatus includes a nozzle formed on a surface of a substrate, and a fluid passage defined in the substrate and fluidically connected to the nozzle, the fluid passage having a first portion that substantially lies on a first plane, a second portion that substantially lies on a second plane different from the first plane, and a connecting passage fluidically connecting the first portion to the second portion.

  • Patent number: 9670351
    Abstract: A flexible tubing material includes a radiation crosslinked blend of a first elastomeric polymer including a styrenic thermoplastic elastomer, an ethylene vinyl acetate elastomer, a polylefin elastomer with a second elastomeric polymer including a polyolefin elastomer, a diene elastomer, or combination thereof, with the proviso that the first elastomeric polymer and the second elastomeric polymer are different. In an embodiment, a method of making a material includes providing the first elastomeric polymer, providing the second elastomeric polymer, blending the first elastomeric polymer and the second elastomeric polymer, extruding or injection molding the blend, and crosslinking the blend with radiation.

  • Patent number: 9511598
    Abstract: An apparatus includes an inkjet assembly having inkjet nozzles through each of which ink flows at a nominal flow rate as it is ejected from the nozzle onto a substrate. Ink is held under a nominal negative pressure associated with a characteristic of a meniscus of the ink in the nozzle when ejection of ink from the nozzle is not occurring. The apparatus includes recirculation flow paths, each flow path having a nozzle end at which it opens into one of the nozzles and another location spaced from the nozzle end that is to be subjected to a recirculation pressure lower than the nominal negative pressure so that ink is recirculated from the nozzle through the flow path at a recirculation flow rate.

  • Publication number: 20100190686
    Abstract: The present invention relates to the discovery of polypeptide biomarkers excreted into the blood stream (serum or plasma) and/or urine from adipocytes and their use to determine the existence of metabolic syndrome (prediabetic) and/or diabetic conditions (including type 2 diabetes) including insulin resistance and/or glucose intolerance, their use to monitor the state of metabolic syndrome or diabetes toward a state of control and/or cure of the disease state or condition and their use to monitor the long-term health of the patient by determining the existence of metabolic syndrome (prediabetic conditions insulin resistance and/or glucose intolerance) or the existence of type 2 diabetes and to identify potential antidiabetes agents. Methods of identifying potential agents to be used in the treatment of metabolic syndrome and/or type2 diabetes and assays for assisting in the diagnosis of metabolic syndrome and/or type 2 diabetes are additional aspects of the invention.
