  • Publication number: 20190137440
    Abstract: Apparatus and associated methods relate to a micro-electro-mechanical system (MEMS) based gas sensor including an electrolyte contacting one or more top electrode(s) arranged on the bottom surface of a top semiconductor substrate (TSS), and one or more bottom electrode(s) arranged on the top of a bottom semiconductor substrate (BSS), the TSS and BSS joined with an adhesive seal around the electrolyte, the sensor including one or more capillaries providing gaseous communication to the electrolyte from an external ambient environment. The electrodes may be electrically accessed by one or more vias to externally accessible bond pads. In some examples, an electrical connection may be made from an additional bond pad on top of the TSS to the electrolyte. Various embodiments may reduce the size of various gas sensors to advantageously allow their inclusion into portable electronic devices.

  • Publication number: 20190040274
    Abstract: The present disclosure relates to solutions for forming a fluoropolymer coatings, comprising: i) an organic solvent, and dissolved therein ii) a fluoropolymer comprising repeat units arising from specific fluoroolefin, alkyl or aryl vinyl ether and alkenyl silane monomers. The present fluoropolymer solutions have long shelf stability life, minimal to no formation of insoluble residue or gel over the period between their manufacture and use, are of a viscosity that allows for facile filtration and so are substantially free from undesirable submicron size particles, have a dissolved polymer content such that the solutions are of utility in commercial single-coat coating processes, and afford fluoropolymer coatings on substrates that have excellent adhesion to the substrate during use and over the lifetime of the electronic device.

  • Publication number: 20190003326
    Abstract: Compliant bellow seal may be axially disposed between first and second cooling plates bounding first and second cooling passages between cooling plates and first and second stage disks in turbine. Bellow seal includes two or more convolutions with oppositely facing forward and aft sealing surfaces, which may be flat, on forward and aft annular sealing walls and cylindrical annular outer and inner contact and sealing surfaces on and facing radially outwardly or inwardly from one of the convolutions. A snake bellow seal embodiment may have at least two of the convolutions being full convolutions of unequal width and a forwardmost partial convolution including the sealing wall. Bellow seal may allow turbine cooling flow from an inter-stage radial face spline to flow through inner openings of second cooling passage and block first stage disk cooling air from flowing through inner openings of first cooling passage.

  • Publication number: 20180046947
    Abstract: The system enables a data processing framework that polls for files using a listener, controls the workflow using event driven logic, processes financial transactions, and creates a business to business trading partner network. The listener ensures the reliability and data integrity of input files and performs archiving functions. The payment management functions automatically processes transactions, including payor (e.g., the buyer) initiated payments to a payee (e.g., a supplier) by utilizing a flexible, decoupled processing architecture. A payment management computer identifies a universal identifier for each entity and forms relationships and hierarchies in order to increase efficiency of the trading partner network. Metadata describes the format, validation and relationships for a wide variety of financial account data.

  • Publication number: 20170161896
    Abstract: Methods and systems for identifying optimized ablation targets for treating and preventing arrhythmias sustained by reentrant circuits are described. The methods comprise receiving at least one mesh generated from one or more images of a patient's heart, receiving activation data generated from one or more simulations of electrical-signal propagation over the at least one mesh, generating at least one flow graph based on the activation data and the at least one mesh, and applying a max-flow min-cut algorithm to the at least one flow graph to determine at least one of a number, one or more dimensions, and one or more locations of one or more ablation targets. Non-transitory computer-readable media storing a set of instructions for treating and preventing arrhythmias sustained by reentrant circuits are also described.

  • Publication number: 20170113935
    Abstract: Apparatus and method are disclosed for plasma synthesis of graphitic products including graphene. A plasma nozzle is coupled to a reaction chamber. A process gas is supplied to the plasma nozzle, the process gas comprising a carbon-containing species. Radio frequency radiation is supplied to the process gas within the plasma nozzle, so as to produce a plasma within the nozzle in use, and thereby cause cracking of the carbon-containing species. The plasma nozzle is arranged such that an afterglow of the plasma extends into the reaction chamber. The cracked carbon-containing species also passes into the reaction chamber, and the cracked carbon-containing species recombines within the afterglow, so as to form the graphitic products including graphene.

  • Patent number: 9567419
    Abstract: This invention pertains to a novel perfluoroalkyl-crosslinked fluoropolymer with perfluoroether pendant groups. The perfluoroalkyl-crosslinked fluoropolymer hereof is particularly well-suited for use in chemically and thermally aggressive environments, in part by virtue of the highly stable perfluoroalkyl crosslink. The perfluroalkyl-crosslinked fluoropolymer hereof can be prepared by crosslinking in situ a crosslinkable precursor in the form of a shaped article. A crosslinkable precursor is a fluoropolymer having a dichloroamino-functionalized functionalized perfluoroether pendant group.
