  • Patent number: 11844724
    Abstract: A surgical method of cataract fragmentation and extraction via microbubble cavitation is described. In particular, gas-filled microbubbles are injected into a lens capsule of a subject's eye, and cavitation of the microbubbles is activated by applied ultrasound energy. The ultrasound energy can be applied from an external device. The cavitation fragments cataract tissues without damaging other tissue, such as the lens capsule. Fragmented lens material is then aspirated from the lens capsule. The method can be used alone or in conjunction with other methods, such as phacoemulsification.

  • Patent number: 11835733
    Abstract: Optical wavefront shaping has been the standard technique to control light through scattering media. Implicit in this dominance is the assumption that knowledge of the optical phase is a necessity for optical control through scattering media. In this paper, we challenge this assumption by reporting on an intensity-only approach for light control through (or reflected from) a disordered scattering medium—optical-channel-based intensity streaming (OCIS). Instead of actively tuning the interference between the optical paths via wavefront shaping, OCIS can control light and transmit information through or from scattering media with linear intensity operation, which not only simplifies and speeds up the system but also enables new applications. We experimentally created focus patterns through scattering media in a sub-millisecond timescale with a phase-manipulation-free setup. We also demonstrate that, unlike wavefront shaping, OCIS can readily generate distinct energy null points through scattering media.

  • Publication number: 20230380744
    Abstract: Medical diagnostic devices and related methods of use are described in which one or multiple coils in a sensor, each coil connected with an RLC circuit and frequency counter, are held against a patient's head at predetermined cranial locations. Frequencies of the RLC circuit are measured and compared against those taken from known, control heads, to determine whether there is a medical problem and what type of problem. In some instances, too high of frequencies can reveal pooled blood in the head, a sign of hemorrhagic stroke, while too low of frequencies imply lack of blood supply, a sign of ischemic stroke. A head-mountable frame can assist a first responder in securing and guiding the coils and, along with fiducials, allow for automatic comparison of frequencies with the correct control data.

  • Patent number: 11830983
    Abstract: Electrolyte solutions including at least one anhydrous fluoride salt and at least one non-aqueous solvent are presented. The fluoride salt includes an organic cation having a charge center (e.g., N, P, S, or O) that does not possess a carbon in the ?-position or does not possess a carbon in the ?-position having a bound hydrogen. This salt structure facilitates its ability to be made anhydrous without decomposition. Example anhydrous fluoride salts include (2,2-dimethylpropyl)trimethylammonium fluoride and bis(2,2-dimethylpropyl)dimethylammonium fluoride. Combining these fluoride salts with at least one fluorine-containing non-aqueous solvent (e.g., bis(2,2,2-trifluoroethyl)ether; (BTFE)) promotes solubility of the salt within the non-aqueous solvents. The solvent may be a mixture of at least one non-aqueous, fluorine-containing solvent and at least one other non-aqueous, fluorine or non-fluorine containing solvent (e.g., BTFE and propionitrile or dimethoxyethane).
