Publication number: 20240122080Abstract: A superconductor device includes a high superconductivity transition temperature enhanced from the raw material transition temperature. The superconductor device includes a matrix material and a core material. The enhancing matrix material and the core material together create a system of strongly coupled carriers. A plurality of low-dimensional conductive features can be embedded in the matrix. The low-dimensional conductive features (e.g., nanowires or nanoparticles) can be conductors or superconductors. An interaction between electrons of the low-dimensional conductive features and the enhancing matrix material can promote excitations that increase a superconductivity transition temperature of the superconductor device.Type: ApplicationFiled: October 9, 2023Publication date: April 11, 2024Inventors: Philipp Braeuninger-Weimer, Nathan P. Myhrvold, Conor L. Myhrvold, Cameron Myhrvold, Clarence T. Tegreene, Roderick A. Hyde, Lowell L. Wood, JR., Muriel Y. Ishikawa, Victoria Y.H. Wood, David R.

Publication number: 20230015425Abstract: Light extraction efficiency of existing semiconductor light emitting devices can be increased significantly by introducing a nanoparticle ‘meta-grid’ on top of a conventional light emitting diode (LED) chip, within its usual encapsulating packaging or casing. The ‘meta-grid’ is essentially a monolayer or a 2D array of sub-wavelength metallic nanoparticles (NPs) with sub-wavelength inter-particle separation. The local dielectric environment around the NPs and within the gaps between the NPs could be the same as the encapsulant, or any other optically transparent material with refractive index close to that of the encapsulant. Upon optical excitation, the collective oscillations of conduction electrons, or surface plasmon, of the metallic NPs give rise to localized surface plasmon resonances.Type: ApplicationFiled: July 11, 2022Publication date: January 19, 2023Inventors: Debabrata SIKDAR, Alexei KORNYSHEV, Joshua EDEL, John Brian PENDRY

Patent number: 10136437Abstract: An automatically adjustable radiofrequency link system includes a radiofrequency transmitter configured to transmit a signal at a frequency of transmission within an extremely high frequency (EHF) band. The system further includes a receiving device configured to receive the transmitted signal and provide feedback to a processing circuit communicatively coupled to the transmitter and the receiving device, wherein the feedback is related to the received signal. The processing circuit is configured to determine required signal properties based on the feedback and determine signal loss properties including an effect of atmospheric absorption, as a function of frequency; determine a modification to the transmitted signal using the signal loss properties and the required signal properties; and adjust the frequency of transmission to obtain a desired transmission signal using the modification.Type: GrantFiled: November 20, 2017Date of Patent: November 20, 2018Assignee: Elwha LLCInventors: Jeffrey A.

Patent number: 9691500Abstract: A digital memory device includes a moveable element that is configured to move between a first stable position and a second stable position, where the moveable element comprises a first conducting area. The digital memory device further includes a second conducting area on the surface of a substrate. At the first stable position of the moveable element, a first gap exists between the first conducting area and the second conducting area. At the second stable position of the moveable element, a second gap that is smaller than the first gap exists between the first conducting area and the second conducting area. In at least the second stable position, an attractive Casimir force between the moveable element and the substrate holds the moveable element in the stable position.Type: GrantFiled: September 14, 2015Date of Patent: June 27, 2017Assignee: Elwha LLCInventors: Kenneth G.
