  • Patent number: 11961533
    Abstract: Disclosed are devices, systems, apparatus, methods, products, and other implementations, including a method comprising obtaining, by a device, a combined sound signal for signals combined from multiple sound sources in an area in which a person is located, and applying, by the device, speech-separation processing (e.g., deep attractor network (DAN) processing, online DAN processing, LSTM-TasNet processing, Conv-TasNet processing), to the combined sound signal from the multiple sound sources to derive a plurality of separated signals that each contains signals corresponding to different groups of the multiple sound sources. The method further includes obtaining, by the device, neural signals for the person, the neural signals being indicative of one or more of the multiple sound sources the person is attentive to, and selecting one of the plurality of separated signals based on the obtained neural signals. The selected signal may then be processed (amplified, attenuated).

  • Publication number: 20240115987
    Abstract: A dual function material is provided that captures carbon dioxide from ambient air, i.e., direct air capture, and converts the CO2 to a desired product such as methane. The material includes a high surface area carrier such as Al2O3 upon which catalysts and alkaline adsorbents are positioned proximate each other. In the presence of reactive gas such as hydrogen, the catalysts reduce the adjacent adsorbents to generate additional active sites and enhance the amount of CO2 captured by the material. Once the material becomes saturated with CO2, hydrogen is reintroduced to reduce the catalyst, such as ruthenium, at which time the adsorbed CO2 can migrate from the adsorbent to the catalyst for catalytic conversion to methane. The materials can be employed in isothermal, cyclic reactor systems where target species are bound and then desorbed to reactivate the material, e.g., bind more target species for desorption and/or conversion to additional product.

  • Patent number: 11940616
    Abstract: A switchable light transmission module is disclosed that includes a substrate having a first surface defining at least part of an enclosed volume, a porous layer disposed on the first surface and in fluid communication with the enclosed volume, and a reservoir in fluid communication with the enclosed volume. The reservoir is configured to supply a fluid to the sealed volume such that the fluid contacts the porous layer. The fluid has a refractive index that is close to the refractive index of the porous layer, has a high wettability for the porous layer, and does not dissolve the porous layer. When in a dry state, voids in the porous layer are filled with air which has a much different refractive index than the porous layer itself, resulting in a surface that is reflective and not very transmissive.

  • Publication number: 20240085681
    Abstract: This application describes Swept, Confocally-Aligned Planar Excitation (SCAPE) microscopy systems that incorporate a gradient index (GRIN) lens to relay images from their distal tip to their proximal tip so that 3D images of deep tissue can be captured, without undue loss of light. A zero working distance feature can be designed into the third objective to ensure that the light that exits the second objective in the SCAPE system is not lost. Alternatively, a tapered fiber bundle may be positioned between the second objective and the third objective in the SCAPE system to ensure that the light that exits the second objective is not lost. As yet another alternative, direct detection at the intermediate image plane without using a third objective can ensure that the light that exits the second objective in the SCAPE system is not lost.
