Abstract:
An inflatable platform that is utilized on the ocean or other bodies of water for relaxation, entertainment, or other recreational purposes includes two floating bodies. The larger floating body has a recess with a mesh panel so the user may access water filtered by the mesh panel while relaxing on the larger floating body. The user may place the smaller floating body next to the larger floating body to create more space for another user or may put the smaller floating body into the recess and use the present invention as a swim platform, tanning deck, or other recreational purpose.
Abstract:
A filter package is provided with a support structure, a filter device having terminals, impedance matching circuits formed on the support structure and electrically connected to at least some of the terminals of the filter device, and at least one electrical ground structure electrically connected to the impedance matching circuits. Moreover, the filter package has an outer housing to contain the support structure, filter device, impedance matching circuits, and at least one ground structure.
Abstract:
A large mode field diameter optical fiber is disclosed. It is a single mode optical fiber which has a core and a cladding. The core of this fiber has two regions, an inner core region and an outer core region which has a refractive index lower than that of the inner core region. The inner core region is doped with a rare-earth element, such as Er2O3, and a co-dopant, such as Al2O3, and the outer core region is doped with a dopant such as GeO2. The types and amounts of the dopants and co-dopants are adjusted to obtain a fiber with a mode field diameter greater than 5.5 μm at a wavelength of 1550 nm.

Abstract:
An apparatus for opening and closing of a sliding door with a foot along a sliding axis, including: a base securable to the sliding door, the base defining base first and second ends and a base longitudinal axis extending therebetween, the base longitudinal axis being substantially parallel to the sliding axis when the apparatus is operatively secured to the sliding door, the base defining opposed base first and second surfaces each extending between the base first and second ends, the base second surface facing the sliding door when the apparatus is operatively secured to the sliding door; a first protuberance extending from the base first surface; and a second protuberance extending from the base first surface, the first and second protuberances being spaced apart from each other along the base longitudinal axis.
Abstract:
An optically active glass and an optical fiber comprising such glass, having reduced photodarkening properties are provided. The optically active glass is mainly composed of silica representing from about 50 to 98 mol % of the glass. It also includes at least one active ion, such as a rear-earth ion, which induces a photodarkening effect in optical properties of the glass. Moreover, the glass includes an effective amount of phosphorus oxide providing the photodarkening reducing effect, preferably in an amount of from about 1 to 30 mol %. A method for reducing a photodarkening effect in optical properties of an optically active glass including the step of introducing phosphorus oxide to the glass is also provided.
Abstract:
A light-emitting device is provided which includes a gain medium having an optically-active phosphosilicate glass, wherein the phosphosilicate glass includes at least one active ion dopant and from about 1 to 30 mol % of phosphorus oxide. The phosphorous oxide may be present in an effective amount for reducing any photodarkening effect and increasing the saturation energy of the system. The active ion dopant may be a rare earth dopant. The light-emitting device may include an optical waveguide, the optical waveguide including the gain medium. The optical waveguide may have a core and at least one cladding, and the gain medium having the phosphosilicate glass may be found in the core and/or in one of the cladding
