  • Patent number: 11974139
    Abstract: Techniques for modelling a radio network in a geographic region utilizing shared spectra are disclosed. Population data is obtained for the geographic region. A number of radios per channel in the geographic region, N?, is determined. Candidate geographic location for radios in the geographic region are determined. For every channel in the shared spectra, at least one of a static dataset and a dynamic dataset is determined. At least one set of output data, that is a statistical characterization of the radio network, is generated using at least one of the static dataset and the dynamic dataset, to aid in design of the radio network.

  • Patent number: 8853932
    Abstract: Techniques described herein generally relate to methods of manufacturing devices and devices including a filament having therein or coated with a catalyst and carbon nanotubes. The device may be configured to produce light with a luminary characteristic having a value higher than a value of the luminary characteristic of a device having an uncoated filament at a same operating condition. The luminary characteristic may include one or more of device irradiance or light efficiency. The filament may be a tungsten filament, and the carbon nanotubes may include multiwall carbon nanotubes or single wall carbon nanotubes. The filament may be coated with the carbon nanotubes using one or more deposition techniques including electric arc discharge, laser ablation and chemical vapor deposition (CVD). The filament may be coated with the catalyst using a method including one or more of electroless plating, electroplating, dip coating, spin coating, and radio frequency (RF) sputtering.

  • Publication number: 20120132864
    Abstract: A composition includes a substrate and a carbon filament where the carbon filament has a first end in contact with the substrate and a second end that is distal to the substrate. The carbon filament may be a carbon nanofiber or carbon nanocoil. The substrate may be a glass fiber and the carbon filament may be radially attached to the glass fiber.
