Abstract: In one embodiment, a coupler includes a glass tube having a refractive index n3 and a passageway, a first optical waveguide and a second optical waveguide positioned within the passageway, each of the first optical waveguide and the second optical waveguide comprising a core surrounded by a cladding. The glass tube further includes a tapered region having a taper length. A coupling region is present between the first optical waveguide and the second optical waveguide within the tapered region. A refractive index of the cladding is less than a refractive index of the core, and a lowest refractive index of the cladding of the first optical waveguide and the second optical waveguide is n2. Additionally, n3 is lower than n2 such that a value of ?2-3 is 0.07%??2-3?0.125, where ?2-3 equals (n22?n32)/2n22.

Abstract: An extraction cleaner having a cleanout tool for use with a surface cleaning apparatus such as an extraction cleaner or vacuum cleaner includes a nozzle cleaning implement and a brush cleaning implement.

Abstract: A cargo barrier for use in a vehicle, the cargo barrier broadly comprising a cargo guard, a guard frame, an elongated connector member, left and right seat mounting brackets, left and right lower extension legs, and left and right lower mounting brackets for mounting the cargo barrier in a first configuration in which the passenger seats are lowered and a second configuration in which the passenger seats are in an upright position.
