Patent • #US9465274B1. The various technologies presented herein relate to utilizing photons at respective idler and signal frequencies to facilitate generation of photons at a pump frequency. A strong pump field can be applied at the ωi and the ωs frequencies, with the generated idler and signal pulses being utilized to generate...

Patent • #US7943116B1. A method for forming non-agglomerated brookite TiO2 nanoparticles without the use of expensive organic surfactants or high temperature processing. Embodiments of this invention use titanium isopropoxide as the titanium precursor and isopropanol as both the solvent and ligand for ligand-stabilized brookite-phase titania. Isopropanol molecules serve as the ligands interacting...

Patent • #US7745315B1. A method for forming vertically oriented, crystallographically aligned nanowires (nanocolumns) using monolayer or submonolayer quantities of metal atoms to form uniformly sized metal islands that serve as catalysts for MOCVD growth of Group III nitride nanowires.

Patent • #US8987754B1. A highly directional thermal emitter device comprises a two-dimensional periodic array of heavily doped semiconductor structures on a surface of a substrate. The array provides a highly directional thermal emission at a peak wavelength between 3 and 15 microns when the array is heated. For example, highly doped silicon...

Patent • #US11557019B1. A method for efficient image registration between two images in the presence of inlier-poor domains includes receiving a set of candidate correspondences between the two images. An approximate homography between the two images is generated based upon a first correspondence in the correspondences. The set of candidate correspondences is...

Patent • #US10214415B1. A silicon carbide based MOS integrated circuit is monolithically integrated with a suspended piezoelectric aluminum nitride member to form a high-temperature-capable hybrid MEMS-over-MOS structure. In the integrated structure, a post-MOS passivation layer of silicon carbide is deposited over the MOS passivation and overlain by a structural layer of the...

Patent • #US12038285B1. A hybrid inertial navigation system and method are provided. The system includes a conventional inertial measurement unit (with a three-axis accelerometer and a three-axis gyroscope operating at a high data rate and low sensitivity), light pulse atom interferometer accelerometer and gyroscope (operating at a low data rate and high...

Patent • #US7875101B2. A portable, non-cryogenic, oxygen generation system capable of delivering oxygen gas at purities greater than 98% and flow rates of 15 L/min or more is described. The system consists of two major components. The first component is a high efficiency membrane capable of separating argon and a portion of...

Patent • #US7985868B1. We describe the preparation and characterization of two zinc hybrid luminescent structures based on the flexible and emissive linker molecule, trans-(4-R,4′-R′) stilbene, where R and R′ are mono- or poly-coordinating groups, which retain their luminescence within these solid materials. For example, reaction of trans-4,4′-stilbenedicarboxylic acid and zinc nitrate in...

Patent • #US9556528B2. Hybrid thermochemical water splitting systems are disclosed that thermally reduces metal oxides particles to displace some but not all of the electrical requirements in a water splitting electrolytic cell. In these hybrid systems, the thermal reduction temperature is significantly reduced compared to two-step metal-oxide thermochemical cycles in which only...

Patent • #US9279188B2.

Patent • #US11387802B1. A hybrid ferroelectric/non-ferroelectric piezoelectric microresonator is disclosed. The hybrid microresonator uses a ferroelectric layer as the actuator as ferroelectric materials typically have higher actuation coefficients than non-ferroelectric piezoelectric materials. The hybrid microresonator uses a non-ferroelectric piezoelectric layer as the sensor layer as non-ferroelectric piezoelectric materials typically have higher sensing...

Patent • #US10666222B1. An amplifying radiofrequency device includes a piezoelectric film and a semiconductor amplifier layer. The piezoelectric film is conformed as an acoustic waveguide. The piezoelectric film has a principal acoustic propagation direction parallel to the principal conduction direction of the amplifier layer. Interdigitated transducers are positioned on the piezoelectric film...
