Publication number: 20230375766Abstract: A method of making a polarizer can include applying a liquid with solid inorganic nanoparticles dispersed throughout a continuous phase, then forming this into a different phase including a solid, interconnecting network of the inorganic nanoparticles. This method can improve manufacturability and reducing manufacturing cost. This method can be used to provide an antireflective coating, to provide a protective coating on polarization structures, to provide thin films for optical properties, or to form the polarization structures themselves.Type: ApplicationFiled: July 31, 2023Publication date: November 23, 2023Inventors: Bradley R.

Publication number: 20230333282Abstract: Optical metasurfaces can manipulate a light wavefront without traditional lenses. They can include pillars with subwavelength dimensions on a substrate. The pillars can vary in size, shape, and spacing across a surface of the substrate. Each pillar size and shape can diffract incident light and provide a unique electromagnetic response. The metasurface can provide desired light wavefront manipulation without the thickness of traditional lenses. The metasurface can overcome the aberration problem of traditional lenses. An overcoat layer can be located at a distal-end of the pillars. Pillar pitch can be adjusted for uniform spacing between pillars, and uniform overcoat coverage. The overcoat layer can protect the pillars. An alternative to the overcoat layer is a solid fill-material filling gaps between the pillars.Type: ApplicationFiled: February 21, 2023Publication date: October 19, 2023Inventors: Daniel Bacon-Brown, Bradley R. WILLIAMS

Patent number: 11010694Abstract: The disclosed embodiments relate to a system that facilitates deployment of utility repair crews to nodes in a utility network. During operation, the system determines a node criticality for each node in the utility network based on a network-reliability analysis, which considers interconnections among the nodes in the utility network. The system also determines a node failure probability for each node in the utility network based on historical weather data, historical node failure data and weather forecast information for the upcoming weather event. The system uses the determined node criticalities and the determined node failure probabilities to determine a deployment plan for deploying repair crews to nodes in the utility network in preparation for the upcoming weather event. The system then presents the deployment plan to a person who uses the deployment plan to deploy repair crews to be available to service nodes in the utility network.Type: GrantFiled: March 28, 2018Date of Patent: May 18, 2021Assignee: Oracle International CorporationInventors: Kenny C.

Patent number: 10937114Abstract: During operation, the system receives a set of input signals containing electrical usage data from a set of smart meters, which gather electrical usage data from customers of the utility system. The system uses the set of input signals and a projection technique to produce projected loadshapes, which are associated with electricity usage in the utility system. Next, the system identifies a closest time period in a database containing recent empirically obtained load-related parameters for the utility system, wherein the load-related parameters in the closest time period are closest to a present set of load-related parameters for the utility system. The system then iteratively adjusts the projected loadshapes based on changes indicated by the load-related parameters in the closest time period until a magnitude of adjustments falls below a threshold. Finally, the system predicts electricity demand for the utility system based on the projected loadshapes.Type: GrantFiled: March 15, 2019Date of Patent: March 2, 2021Assignee: Oracle International CorporationInventors: Benjamin P.
