Publication number: 20220028615Abstract: Methods of processing a capacitor device with high energy density and high extraction efficiency based on sol-gel films. The films can be formed by use of a single precursor, including siloxane precursors bearing a polar group on a flexible tethering group. The sol-gel compositions used in the formation of films can have high dielectric permittivity, low dielectric loss, high breakdown strength and high-energy storage properties. The methods can be well suited for both high energy density and high power density to provide enhanced energy storage capabilities for discrete, embedded or on-chip integrated capacitor applications, gate dielectrics for transistors and displays, capacitive touch screens, light weight mobile defibrillators, filters for cellular devices, electric propulsion, electric vehicles, power invertors for microgrid storage, load leveling of transients on a wide range of timescales for medium voltage electric grids.Type: ApplicationFiled: October 5, 2021Publication date: January 27, 2022Inventors: Joseph W. Perry, Mohanalingam Kathaperumal, Yun Sang Kim

Patent number: 8597549Abstract: Disclosed are highly efficient multiphoton absorbing compounds and methods of their use. The compounds generally include a bridge of pi-conjugated bonds connecting electron donating groups or electron accepting groups. The bridge may be substituted with a variety of substituents as well. Solubility, lipophilicity, absorption maxima and other characteristics of the compounds may be tailored by changing the electron donating groups or electron accepting groups, the substituents attached to or the length of the pi-conjugated bridge. Numerous photophysical and photochemical methods are enabled by converting these compounds to electronically excited states upon simultaneous absorption of at least two photons of radiation. The compounds have large two-photon or higher-order absorptivities such that upon absorption, one or more Lewis acidic species, Lewis basic species, radical species or ionic species are formed.Type: GrantFiled: June 26, 2007Date of Patent: December 3, 2013Assignee: The California Institute of TechnologyInventors: Brian Cumpston, Matthew Lipson, Seth R.

Patent number: 6322931Abstract: The present invention comprises an optical data storage system utilizing a host material and molecules that exhibit non-linear absorption dissolved therein. The non-linear absorbing molecules allow for energy in the form of heat to be generated during the optical data storage process. This heat provides for localized alterations to occur in the pre-formatted holographic grating. The non-linear feature of these molecules allow for alterations to occur at specific depths and locations within the storage medium while limiting the secondary effects on other locations within the storage medium. The molecules exhibiting non-linear absorption may be selected from the group of molecules exhibiting two-photon absorption or reverse saturable absorption. The invention also comprises a method for preparing the optical storage medium, an optical data storage device comprising the optical data storage medium and having a format hologram stored within the medium.Type: GrantFiled: July 29, 1999Date of Patent: November 27, 2001Assignee: Siros Technologies, Inc.Inventors: Brian H.

Patent number: 5255428Abstract: An optical voltage sensor utilizing an electrooptic polymer is disclosed for application to electric power distribution systems. The sensor, which can be manufactured at low cost in accordance with a disclosed method, measures voltages across a greater range than prior art sensors. The electrooptic polymer, which replaces the optical crystal used in prior art sensors, is sandwiched directly between two high voltage electrodes. Voltage is measured by fiber optical means, and no voltage division is required. The sample of electrooptic polymer is fabricated in a special mold and later mounted in a sensor housing. Alternatively, mold and sensor housing may be identical. The sensor housing is made out of a machinable polymeric material and is equipped with two opposing optical windows. The optical windows are mounted in the bottom of machined holes in the wall of the mold. These holes provide for mounting of the polarizing optical components and for mounting of the fiber optic connectors.Type: GrantFiled: April 3, 1991Date of Patent: October 26, 1993Assignee: California Institute of TechnologyInventors: Allan Gottsche, Joseph W.

Patent number: 5062693Abstract: A single material (not a multi-element structure) spatial light modulator (50) may be written to (30), as well as read out from (80), using light (20). The device has tailorable rise and hold times dependent on the composition and concentration of the molecular species used as the active components. The spatial resolution of this device is limited only by light diffraction as in volume holograms. The device may function as a two-dimensional mask (transmission or reflection) or as a three-dimensional volume holographic medium. This device, based on optically-induced electron transfer, is able to perform incoherent to coherent image conversion or wavelength conversion over a wide spectral range (ultraviolet, visible, or near-infrared regions).Type: GrantFiled: February 15, 1990Date of Patent: November 5, 1991Assignee: The United States of America as represented by the Administrator of the National Aeronautics and AdministrationInventors: David N.

Apparatus and method for removing and burning hydrocarbon vapors using an internal combustion engine
Patent number: 4846134Abstract: An apparatus and method are disclosed for accumulating hydrocarbon vapor and rendering the vapor environmentally safe by combustion. An internal combustion engine is attached to an interface which accumulates hydrocarbon vapor present in the soil after a spill or leakage from a storage tank or transfer lines. The vacuum of the internal combustion engine present in the intake manifold is used to draw the hydrocarbon vapors from the soil into the interface and then into the engine where they are burned. A catalytic converter of conventional design cleans the end exhaust removing any remaining hydrocarbon pollutants.Type: GrantFiled: March 30, 1988Date of Patent: July 11, 1989Assignee: V. R.
