  • Patent number: 9753219
    Abstract: A device and system for coupling light into and out of a photonic integrated circuit. The forked grating coupler device applies a forked grating structure to the design of the diffracting lines in an integrated optics grating coupler to make the device compatible with vortex light beams to or from free space, bulk optics, or special optical fiber that can propagate vortex modes. These diffracting lines, which can be grooves, or ridges, or a photonic metamaterial discontinuity arranged in a continuous or intermittent curve, follow the forked diffraction pattern lobes over a two-dimensional surface. The resulting device can therefore absorb or radiate a vortex beam mode at near-normal incidence to a PIC and transform that vortex mode to a transverse electric (TE) or transverse magnetic (TM) waveguide mode traveling along a slab or strip optical waveguide parallel to the surface of the IC.

  • Publication number: 20170138337
    Abstract: A wind energy extraction apparatus utilizing a separate surface enclosing the turbine rotor is disclosed. An embodiment of the present invention includes a slotted and un-slotted duct of specified geometry enclosing a wind turbine rotor in such a manner as to provide acceleration of the ambient air though the rotor at a velocity above that which an open rotor exposed to the freestream would experience, thereby resulting in an increased amount of energy extraction relative to a comparable open rotor. In one aspect, the wind turbine rotor is positioned in the duct at a location downstream of the smallest cross-sectional area of the duct as this will provide the maximum power output. According to another aspect, the rotor geometry is such as to incorporate the effect of the duct on the incoming wind velocity profile.

  • Patent number: 9511655
    Abstract: Specific elements of the Urb&GO ecosystem include a battery electric vehicle (BEV) that is convertible between a driveable mode and a stowable mode where the height of the roof area of the vehicle is lowered when the vehicle is stowed. The stowable mode reduces the volume of the BEV allowing for the storage of more vehicles per cubic feet of storage or parking space. The infrastructure for the BEV includes various configurations for charging and storage facilities. The charging facilities may include wind turbines; solar polar of other renewable power. The proposed Urb&GO concept reduces traffic and congestion and eliminates exhaust fumes reducing greenhouse gas emissions. The “Park & Ride” idea can be used to allow people to use Urb&GO Vehicles to commute to the city. Customer and public ownership and leasing study options are possible with this concept.

  • Publication number: 20160276109
    Abstract: Solid, or highly viscous, organic electrolytes consisting of alkylimidazolium cation with alkyl, PEGylated and fluorinated side chains of different molecular weights were synthesized and characterized (cf. chemical structures in Schemes 1 and 2). The PEGylated/fluorinated imidazolium iodide is a solid organic electrolyte that has a conductivity of about 2×10?5 S/cm at 30° C. The ionic conductivity could be significantly increased (1.11×10?4 S/cm at 30° C. and S/cm at 2.88×10?3 at 90° C.) by blending the PEGylated/fluorinated imidazolium iodide with another solid electrolyte, 1-ethyl-3-methylimidazolium iodide (EtMlml). The PEGylated imidazolium iodides synthesized in the present work have conductivities in the range 1.6×10?4 S/cm to 2×10?4 S/cm at 30° C. and viscosities in the range 620 cP to 720 cP at 30° C. The iodide counter ion in the present electrolytes supplies the anion for the I?/I3? redox mediators for DSSCs.

A modifying compound comprised of an imidazole reactive group, a linker, and a ligating group is contacted with the recombinant protein, and a cooperative bond forms between the ligating group and the oligohistidine tag in the presence of a metal cation, and a covalent bond forms between the imidazole reactive group and an imidazole ring of the oligohistidine tag followed by the concomitant separation of the imidazole reactive group from the linker. Addition of a metal chelator results in the dissociation of the ligating group and the oligohistidine tag.
