  • Publication number: 20180216278
    Abstract: The present invention provides an attachable cup holder for a laundry detergent container. The attachable cup holder includes a first receiving portion affixed perpendicularly in relation to a second receiving portion via a pair of connection rods. The first receiving portion includes an open loop having a first end and a second end, wherein the open loop removable secures to a spout of a laundry detergent container. The second receiving portion includes a pair of opposing arcuate rod members that receive a cup. The pair of connection rods are affixed to the ends of the open loop and extend downwardly therefrom, wherein a bottom end of each connection rod is affixed to a distal end of an arcuate rod member of the second receiving portion. The opposing arcuate members are disconnected such that they can move away from one another to receive cups having varying diameters.

  • Patent number: 8755647
    Abstract: A frequency-chirped nano-antenna provides efficient sub-wavelength vertical emission from a dielectric waveguide. In one example, this nano-antenna includes a set of plasmonic dipoles on the opposite side of a SiYV4 waveguide from a ground plane. The resulting structure, which is less than half a wavelength long, emits a broadband beam (e.g., >300 nm) that can be coupled into an optical fiber. In some embodiments, a diffractive optical element with unevenly shaped regions of high- and low-index dielectric material collimates the broadband beam for higher coupling efficiency. In some cases, a negative lens element between the nano-antenna and the diffractive optical element accelerates the emitted beam's divergence (and improves coupling efficiency), allowing for more compact packaging.
