Abstract: We utilize high-quality-factor (high-Q) metasurfaces patterned either in or adjacent to electro-optical or thermo-optical materials such as lithium niobate, barium titanate, or thermally-sensitive polymers. The metasurface includes nanoantennas that act as dipole emitters; the particular structure and arrangement of nanoantennas can steer light to particular directions or focus light, The electromagnetic metasurface supports one or more guided mode resonances. The metasurface also includes a perturbation superposed on the metasurface features and configured to couple free-space radiation to the guided mode resonances.

Abstract: Self-isolated lasers are provided by using a chiral metasurface in combination with a spin-selective gain medium and symmetry-breaking (i.e., not linearly polarized) optical pumping. In preferred embodiments the chiral metasurface is resonant, thereby proving an integrated optical resonator to support lasing. The chiral metasurface can be the spin-selective gain medium, or it can be formed on a surface of the spin-selective gain medium, or it can be distinct from the spin-selective gain medium.

Abstract: Systems and methods for selective on-device latency reduction include receiving data requesting that an application associated with a user device be utilized and identifying on-device functionality enabled for the application. Data may be generated that includes a subset of content associated with the on-device functionality and is configured to be utilized by a device in the environment to perform the on-device functionality. This data may be sent to the device in question and may configure the device to process input data associated with the on-device functionality and utilize commands associated with the subset of content based at least in part on processing the input data with the on-device functionality.

Abstract: Techniques for enabling access in a multi-assistant speech processing system are described, where a first assistant system may use components of a second assistant system as data processing components. Runtime operational data and user input data related to the first assistant may be kept separate from the processing data and input data related to the second assistant by propagating a first account ID, for user inputs directed to the first assistant, through the processing pipeline, and using a second account for user inputs directed to the second assistant. A mapping between the first account ID and the second account ID may be accessible to a select number of system components. Handoffs between the two assistants are handled in a manner where data related to one assistant is not accessible by the other assistant.

Abstract: A device for detecting optical chirality includes a metasurface composed of a biperiodic array of nanodisks in the form of a checkerboard array [300], where the nanodisks have diameters d±?/2 such that adjacent nanodisks [302, 304] have diameters that differ by an offset ?. The nanodisks are composed of a dielectric material that is transparent and has a refractive index greater than 2 at a predetermined operational ultraviolet wavelength. The nanodisks have a width-to-height aspect ratio d/h tuned to produce spectral overlap of electric dipole and magnetic dipole modes of incident circularly polarized ultraviolet light.

Abstract: A multi-assistant speech-processing system that centrally determines multiple execution plans to respond to a user input. A central component determines whether a particular input should be processed using a requested assistant or a different assistant or should be terminated. Assistant handoff may be determined based on system policies as well as user input-specific data. A ranked list of execution options may be supplemented by augmented data corresponding to messages to a user. The system may attempt to execute plans in the ranked order until a plan succeeds.

Abstract: A method, a system, and a computer program product provide a method for managing a decentralized venture capital (“VC”) fund in a decentralized autonomous organization (“DAO”) configured to use a secure communication environment. The method includes securing authentication information, including user authentication information. The securing of the authentication information includes using a public key in the process to encrypt the authentication information and then decomposing the authentication information into subcomponents that are distributed randomly across a plurality of member computers. The method further includes recovering the authentication information by recombining the authentication information from its subcomponents then using a private key in the process to decrypt the authentication information.

Abstract: The invention teaches a value exchange for natural resources that is transparent and assured by a layer of distributed trust where tokenized inventory collateralizes derivative products, which enables the inventory to be monetized while located anywhere in the world including in major buying hubs, whereby suppliers, buyers and market makers can execute and settle authenticated transactions, both outright sales and derivative transactions, for natural resources in near real time.

A method of forming a triangular package includes bending side portions of stock material to form the sides of the triangular packaging and shrink wrapping the triangular package causing tabs to cover portions of the triangular package ends.

Abstract: The invention teaches a decentralized autonomous organization (“DAO”) that manages a network of micro home businesses via a secure communication environment. A service provider curates active and passive income opportunities and provides training courses for worker users. A worker user selects a home configured to enable their preferred income opportunities then applies for a mortgage. The mortgage is pre-approved then a bridge loan is provided for construction. After construction is completed, the mortgage retires the bridge loan. Then the worker user occupies the home business and generates active and passive income to pay off the mortgage. Each micro home business is a node in the DAO. The DAO is maintained through competitive bids from service provider users. Disputes are resolved by arbitrator users. The internet of things is used to enable proactive maintenance.

Abstract: Optical sensing of biological targets is provided using a metasurface having guided mode resonances with electric field profiles that extend out from the metasurface. Surface functionalization of such metasurfaces can be used to provide sensing for biological targets, such as nucleic acids, proteins, small molecules, extracellular vesicles, and whole cells. Binding of the target to the surface functionalization can affect the resonance wavelength of the guided mode resonances, thereby providing a sensitive assay for the biological targets.

Abstract: A metasurface optical device composed of three stacked dielectric layers which form an anti-reflective structure for wavelengths in a predetermined operational wavelength range within the visible spectrum. The anti-reflective structure contains a rectangular lattice of rhombohedral perturbations that produce guided-mode resonances within the predetermined operational wavelength range. The guided-mode-resonant dielectric metasurface device is capable of detecting by colorimetric readout the presence and orientation of a linearly birefringent anisotropic medium, such as a fibrous tissue, positioned above the stacked dielectric layers.

The method further includes determining a power level of the probe audio signal and determining a state of the display based on the power level of the probe audio signal.
