  • Patent number: 11567234
    Abstract: Structured beams, Bessel beams, Laguerre Gaussian beams, and focused Gaussian are used as a natural waveguide and its group velocity can be subluminal (slower than the speed of light) as compared to a Gaussian beam in free space. A free space dispersion relation for a Bessel beam, i.e., the dependence of its wavenumber on its angular frequency, is outlined from which the Bessel beam's subliminal group velocity is derived. For reasonable conditions a Bessel light beam has associated parameters that allow slowing near a critical frequency. The application of Bessel beams for a natural optical buffer in free space is presented. Optical transitions and selection rules in materials are altered by structured light carrying orbital angular momentum (OAM). Nano antennas are used to enhance the interactions of structured light.

  • Patent number: 10087087
    Abstract: A water distribution system having a dual use water treatment unit. The same water treatment unit can be used to treat water supplied from a fill port to a storage tank during a fill operation, as well as water leaving the storage tank for supply to one or more points of water use during a supply operation. When a diverter valve is in a fill position, water supplied to the fill port can flow through the diverter valve and to the water treatment unit for treatment then to the storage tank for storage. When the diverter valve is in a supply position, the water from the storage tank can be delivered using means for pressurizing water to the same treatment unit for treatment, then through the diverter valve and to a point of water use device.

  • Patent number: 8568585
    Abstract: A water distribution system including a water storage tank, a water treatment unit, a diverter valve, and interconnecting water conduits arranged so that the same water treatment unit can be used to treat water supplied from a fill port to the storage tank during a fill operation, as well as water leaving the storage tank for supply to one or more points of water use during a supply operation. A diverter valve is provided which is movable between a fill position wherein the water treatment unit is in fluid communication with the fill port and not the point of water use device, and a supply position wherein the water treatment unit is in fluid communication with the at least one point of water use device and not the fill port. When the diverter valve is in the fill position, water supplied to the fill port can thus flow through the diverter valve and to the water treatment unit for treatment then to the storage tank for storage.
