  • Patent number: 9023216
    Abstract: Apparatus is disclosed for substantially reducing the momentum, velocity, or both of a first liquid that is flowing into a second liquid. The device allows one to substantially reduce or even eliminate large-scale turbulent eddies that could otherwise be produced by liquid flowing into or within a vessel, for example in a clarifier. Suitably-sized and positioned plates and baffles induce changes of flow direction in a limited volume. By the time the fluid leaves this volume, the fluid velocity is low, and turbulence is nearly or entirely eliminated. Several of the devices may be placed at different inputs within a single clarifier, and thus increase efficiency further.

  • Patent number: 9023478
    Abstract: Methods involve a combination of polyelectrolyte multilayer (PEM) coating or silane self assembly on a substrate; microcontact printing; and conductive graphite particles, especially size controlled highly conductive exfoliated graphite nanoplatelets. The conductive graphite particles are coated with a charged polymer such as sulfonated polystyrene. The graphite particles are patterned using microcontact printing and intact pattern transfer on a substrate that has an oppositely-charged surface. The method allows for conductive organic patterning on both flat and curved surfaces and can be used in microelectronic device fabrication.

  • Patent number: 9018002
    Abstract: A method to generate siRNAs in vivo is described, as are constructs and compositions useful in the method. The method does not depend on the use of DNA or synthetic constructs that contain inverted duplications or dual promoters so as to form perfect or largely double-stranded RNA. Rather, the method depends on constructs that yield single-stranded RNA transcripts, and exploits endogenous or in vivo-produced miRNAs or siRNAs to initiate production of siRNAs. The miRNAs or siRNAs guide cleavage of the transcript and set the register for production of siRNAs (usually 21 nucleotides in length) encoded adjacent to the initiation cleavage site within the construct. The method results in specific formation of siRNAs of predictable size and register (phase) relative to the initiation cleavage site. The method can be used to produce specific siRNAs in vivo for inactivation or suppression of one or more target genes or other entities, such as pathogens.

  • Patent number: 9016124
    Abstract: An acceleration-triggered or shock-triggered, smart, tunable MEMS switch that may function as both a classic accelerometer and an acceleration threshold detector. A parallel element MEMS device has a stationary and a movable element forming a capacitor. Varying acceleration moves the movable member with respect to the stationary member, thereby changing the capacitance of the device. The capacitance varying may be used, in cooperation with appropriate circuitry, to provide a signal representative of instantaneous acceleration. By applying a biasing voltage, the movable element may be positioned in a predetermined fashion such that acceleration of a predetermined magnitude causes the movable element to pull in (snap down). The movable and stationary elements may function as a switch such that when the predetermined acceleration or shock level occurs, electrodes close, a current flows between the elements so that an external device such as an air bag may be activated.
