Publication number: 20230384501Abstract: A wire grid polarizer (WGP) can include an array of support-ribs on a substrate. Sides of the support-ribs can be inclined to one side. A wire can be applied on an upper-side and distal end of each support-rib, each wire being separate from wires on adjacent support-ribs. The WGP can be made with reduced or no etching.Type: ApplicationFiled: August 9, 2023Publication date: November 30, 2023Inventors: R. Stewart NIELSON, Bradley R. WILLIAMS, Bob WEST

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. WILLIAMS, R. Stewart NIELSON, Anubhav DIWAN, Eric GARDNER, Shaun Patrick OGDEN, Bob WEST

Patent number: 11612047Abstract: It would be advantageous to reduce weight and size of high voltage power supplies, to increase frequency of pulses of high voltage, and to improve control of magnitude of high voltage. The embodiments of high voltage power supplies described herein can solve these problems. The high voltage power supply can be used with an x-ray tube. The high voltage power supply can comprise an array of planar transformers each defining a stage with an AC input and a DC output. Each stage can comprise a pair of flat, coil windings adjacent one another and including a primary winding electrically-coupled to the AC input and configured to induce a current in a secondary winding. At least two stages can be electrically-coupled together in series with the DC output of one stage electrically-coupled to an input of the other stage such that a voltage is amplified across the stages.Type: GrantFiled: March 15, 2021Date of Patent: March 21, 2023Assignee: Moxtek, Inc.Inventors: Sreeram Dhurjaty, David Hoffman, Bob West

Publication number: 20220408536Abstract: A high voltage power supply can be compact with shielded electronic components. The power supply can include multiple stages separated by circuit boards. Electronic components for each stage can be directly soldered to adjacent circuit boards. Traces can pass through and electrically couple electronic components on each side of the circuit board between them.Type: ApplicationFiled: May 25, 2022Publication date: December 22, 2022Inventors: Scott Howard Hardy, Vincent F. Jones, Bob West

Publication number: 20220291434Abstract: A wire grid polarizer can have a protective-layer PL on each wire 12 sidewall SW. The protective-layer PL can protect the sidewall SW from corrosion, oxidation, or both. The protective-layer PL can be absent from or thinner at a distal-end DE of the wire 12, farther from the substrate. Polarizer performance degradation, from the protective-layer PL, can be minimized or eliminated by removing the protective-layer PL from the distal-end DE. The invention is particularly applicable to a wire grid polarizer with multiple layers UL and LL, and the upper-layer UL at the distal-end DE is more resistant to corrosion and oxidation than the embedded lower-layer LL.Type: ApplicationFiled: February 14, 2022Publication date: September 15, 2022Inventors: Bob West, R. Stewart Nielson

Publication number: 20220177078Abstract: A modular boat can be adapted to meet various desired shapes and uses, and can be transportable. The modular boat can include multiple sections configured to be joined together by rod-connection(s), by interlock-connection(s), or both. Each section can be joined to other section(s) to form and use the modular boat, and can be separated from the other section(s) for transportation. Each section can extend from bow to stern and can be joined to the other section(s) at a junction extending from bow to stern. Each rod-connection can include a hole extending perpendicular to the junction, through the sections across the modular boat, and a rod extending through the hole. Each interlock-connection can include a a key inserted into a slot of an adjacent section at the junction.Type: ApplicationFiled: November 26, 2021Publication date: June 9, 2022Inventors: Vincent F. Jones, Matt Free, Bob West
