  • Publication number: 20200379058
    Abstract: Disclosed are devices, systems and methods for assessing the integrity of electrical connections between elements of interfacing electronic devices. In some aspects, a system includes an analysis device having electronics that interface with an assay cartridge inserted into the analysis device, wherein the analysis device is configured to conduct a preflight test in which impedance values for each circuit between the assay cartridge and analysis device are rearranged and assessed to determine the electrical connection integrity of the assay cartridge to the analysis device prior to implementing the assay.

  • Patent number: 10737800
    Abstract: A catalytic inerting system (CIS) architecture includes a fuel tank including a fuel tank inlet and a fuel tank outlet, the fuel tank defining a space for containing a liquid fuel and an ullage space above the liquid fuel containing an ullage gas. A catalytic reactor is in fluid communication with the fuel tank, the catalytic reactor having a catalytic inlet and a catalytic outlet, wherein the catalytic reactor receives an ullage gas flow from the fuel tank outlet and performs a catalytic reaction on the ullage gas to produce a more inert flow from the catalytic outlet to the fuel tank inlet. A bypass line provides a flow pathway between the fuel tank inlet and the fuel tank outlet, thereby bypassing the fuel tank, and a flow control mechanism controls relative flows of the inert flow from the catalytic outlet to the fuel tank inlet versus through the bypass line.

  • Publication number: 20200248302
    Abstract: A method includes depositing a layer of alumina over a silicon substrate, providing a patterned photoresist over the layer of alumina, providing an iron catalyst layer over the patterned photoresist, providing the iron catalyst layer over an exposed portion of the alumina, providing a first iron catalyst site over a first portion of the alumina, providing a second iron catalyst site over a second portion of the alumina, growing a first carbon nanotube on the first iron catalyst site, growing a second carbon nanotube on the second iron catalyst site, infiltrating the first carbon nanotube and the second carbon nanotube with carbon, and cooling both the first carbon nanotube and the second carbon nanotube. The infiltrating strengthens the first carbon nanotube and the second carbon nanotube to not delaminate from the substrate when the first carbon nanotube and the second carbon nanotube are cooled.

  • Publication number: 20200116265
    Abstract: A valve member having a first flow path and a second flow path, and configured to control both flow paths through a filter assembly. The valve member allows control of the two flow streams in a compact space compared to traditional valves. The valve member may require less space to operate due to its compact nature as compared to traditional external valves with multiple handles that each require space to rotate. The valve member may also be used to easily shut-off flow to a filter of a filter assembly without limiting use of another filtration assembly in the same filtration system. Alternatively, the valve member may shut off flow to a corresponding filter of a stand-alone filter assembly that is not connected to another filter assembly. Also, the valve member allows less expensive and more lightweight filtration systems.

  • Publication number: 20190232279
    Abstract: The present disclosure relates to methods and devices for displacing a liquid, gas or solid from a compressible pouch. The compressible pouch is housed in an external housing with holes over the compressible pouch and a label over the external housing/holes and compressible pouch. The label comprises perforations configured to allow a chad to separate but not detach from the label. When a compressive force is applied to the label, the chad separates (but does not detach) from the label allowing the compressive force to be applied to the compressible pouch below and force the fluid, gas or solid from the compressible pouch.

  • Publication number: 20190099623
    Abstract: A radiation therapy system includes a treatment couch positioning assembly that is directly coupled to a fixed structure supporting the linear accelerator of the radiation therapy system. The radiation therapy system can be installed in a radiation therapy facility without the floor of the facility being excavated and a sub-floor structure, such as a base frame, being installed. To laterally position a patient relative to the linear accelerator, the treatment couch positioning assembly of the radiation therapy system is laterally translated via a linear motor, and laterally translates with the treatment couch, rather than cantilevering the treatment couch to either side of the couch positioning assembly.

  • Publication number: 20180237720
    Abstract: Silicone oil-in-water emulsions containing a polysiloxane containing polymer is prepared by first preparing a polysiloxane containing polymer by the polymerisation of siloxane containing monomers and/or oligomers in the presence of an inert organopoly siloxane and/or an organic fluid, a suitable catalyst and optionally an end-blocking agent; and quenching the reaction if required. If required one or more surfactants may be introduced into the polysiloxane containing polymer to form a homogenous oil phase. Water is then added (in an amount of 0.1-10 percent by weight based on total oil phase weight) to the homogenous oil phase to form a water-in-oil emulsion. Shear is applied to the water-in-oil emulsion to cause inversion of the water-in-oil emulsion to an oil-in-water emulsion. Finally, if required the oil-in-water emulsion can be diluted by adding more water.
