  • Patent number: 11882023
    Abstract: Methods, and systems, for Multiagent Pathfinding for Non Dynamic Programming Problems, including a CE method which provides for sampling from a complex probability distribution that is not necessarily known in a closed form. The applications of this method include rare-event simulation, variance reduction for estimation problems, and stochastic optimization. The method iteratively searches for a probability distribution that is “close” to the intended distribution, where the closeness of distributions is measured using the Kullback-Liebler (KL) divergence between the distributions. At each step, the method generates samples according to a current candidate distribution from the family. Next, it uses those current candidate distribution samples to move the distribution toward a new candidate distribution that is closer in the sense of KL divergence to the target distribution.

  • Patent number: 11863994
    Abstract: In an example, a provider system receives from a client device a request for client sign-on access. The provider system sends to the client device a request for identification information of the client. The provider system receives client information associated with a first mobile identification credential (MIC) which the client device received from an authorizing party system (APS), the client having consented to release the client information to the provider system, and the client information having been verified by the APS. The provider system uses the verified client information associated with the first MIC to verify or not verify the identity of the client.

  • Patent number: 11862716
    Abstract: Heterostructures include a layer of a two-dimensional material placed on a multiferroic layer. An ordered array of differing polarization domains in the multiferroic layer produces corresponding domains having differing properties in the two-dimensional material. When the multiferroic layer is ferroelectric, the ferroelectric polarization domains in the layer produce local electric fields that penetrate the two-dimensional material. The local electric fields modulate the charge carriers and carrier density on a nanometer length scale, resulting in the formation of lateral p-n or p-i-n junctions, and variations thereof appropriate for device functions.

  • Patent number: 11860333
    Abstract: Examples are directed toward systems and methods relating to security screening. For example, a screening system includes a sensor array to sense a gravitational field caused by an item, and a conveyor to convey the item through sensing positions for scanning by the sensor array. A controller acquires weight measurement information from sensor elements, and gravitational measurement information from the sensor array. The conveyor incrementally advances the item through additional sensing positions to acquire weight measurement information and gravitational measurement information. The controller performs tomographic reconstruction to generate a tomographic image of the item, using a generated weight map as a static weight input vector and using a generated mass map as a static mass input vector for the tomographic reconstruction.

  • Publication number: 20230420539
    Abstract: A self-aligned lithography process for the fabrication of an electronic device having predefined areas of a second semiconductor material having a second conductivity type deposited into trenches formed in a first semiconductor material layer having a first conductivity type. A single lithography mask is used for etching trenches in the first semiconductor material, enabling cleaning of the trenches, and providing defined areas for the deposition of the second semiconductor material into the first semiconductor material. The presence of the areas of the second semiconductor material within the first semiconductor material creates a heterojunction beneath a metal for the formation of a first type of contact to the first semiconductor material and a second type of contact to the second type of material. By using a single mask for the etching, cleaning, and filling steps, misalignment issues plaguing devices having small (1-2 ?m) feature sizes is eliminated.
