  • Publication number: 20250099300
    Abstract: A device may include an image capturing component to obtain images of an environment of a user, and a light projection system. The light projection system may include a laser source and an optical imager. The device may process, in real-time, images captured by the image capturing component to derive signals for controlling the laser source, provide the signals to the laser source to enable the laser source to generate a laser beam pattern, cause the optical imager to raster scan the laser beam pattern to an absorptive element. The absorptive element may be disposed on or in the user, and positioned proximate to a region-of interest, of the user, that includes neuronal cells. The laser beam pattern may cause the absorptive element to produce acoustic energy that cause depolarization of the neuronal cells. The sensory stimulation may enable the user to visually and/or auditorily perceive the environment.

  • Patent number: 12257186
    Abstract: An aspiration device to be used with an irrigation-aspiration handpiece may comprise a curved body having a radius of curvature based on a human equatorial lens diameter, an interface adapted to attach the curved body to a first end of an aspiration lumen in the irrigation-aspiration handpiece, and multiple aspiration ports formed in the curved body. The multiple aspiration ports may be adapted to draw material into the aspiration lumen when a suction source is used to apply vacuum pressure at a second of the aspiration lumen while the aspiration lumen is attached to the aspiration device. The multiple aspiration ports may be arranged to distribute the vacuum pressure over an aggregate surface area of the multiple aspiration ports while the suction source applies the vacuum pressure.

  • Patent number: 12256970
    Abstract: An embodiment in accordance with the present invention provides a handheld cryoprobe for use in percutaneous cryotherapy of tumorous masses. It includes a probe attached to a CO2 gas dispensing backend. The probe has specifically optimized parameters designed for use with CO2 gas and is made out of a partially hollowed and threaded aluminum rod providing maximum heat exchange. The system backend regulates flow of compressed CO2 gas while throttling and cooling the gas coolant to the cytotoxically low temperatures necessary for targeted tumor cell death. Additionally, the incoming initial stream of CO2 gas is throttled by the Joule-Thomson nozzle on the backend. The low temperature exhaust gas is then used to pre-cool all subsequent incoming gas, resulting in an even lower temperature at the probe tip, which provides a positive feedback loop, continually decreasing the gas's temperature. The temperature drop is caused by the Joule-Thomson effect.

  • Patent number: 12252743
    Abstract: The identification of mutations that are present in a small fraction of DNA templates is essential for progress in several areas of biomedical research. Though massively parallel sequencing instruments are in principle well-suited to this task, the error rates in such instruments are generally too high to allow confident identification of rare variants. We here describe an approach that can substantially increase the sensitivity of massively parallel sequencing instruments for this purpose. One example of this approach, called “Safe-SeqS” for (Safe-Sequencing System) includes (i) assignment of a unique identifier (UID) to each template molecule; (ii) amplification of each uniquely tagged template molecule to create UID-families; and (iii) redundant sequencing of the amplification products. PCR fragments with the same UID are truly mutant (“super-mutants”) if ?95% of them contain the identical mutation.

  • Patent number: 12227854
    Abstract: The present invention is directed to methods for formation of refractory carbide, nitride, and boride coatings without use of a binding agent. The present invention is directed to methods of creating refractory coatings with controlled porosity. Refractory coatings can be formed from refractory metal, metal oxide, or metal/metal oxide composite refractory coating precursor of the 9 refractory metals encompassed by groups 4-6 and periods 4-6 of the periodic table; non-metallic elements (e.g. Si & B) and their oxides (i.e. SiO2 & B2O3) are also pertinent. The conversion of the refractory coating precursor to refractory carbide, nitride or boride is achieved via carburization, nitridization, or boridization in the presence of carbon-containing (e.g. CH4), nitrogen containing (e.g. NH3), and boron-containing (e.g. B2H6) gaseous species. Any known technique of applying the refractory coating precursor can be used.
