  • Publication number: 20240120661
    Abstract: A modular radio frequency (RF) device includes N base units, each including a differential segmented array (DSA) tile with a support board and a two-dimensional (2D) array of electrically conductive tapered projections disposed on the support board. Neighboring pairs of the electrically conductive tapered projections form RF pixels. The N DSA tiles are arranged to form an RF aperture. The N base units are programmed to switch the RF aperture between a first operating mode and a second operating mode. In the first operating mode, the N base units are operated as at least two independent subsets with each subset operating as an RF transmitter or receiver independently of the other subsets. In the second operating mode all N base units coherently combine as a single phased array RF transmitter or receiver.

  • Patent number: 11947506
    Abstract: A computer-implemented method is disclosed for mapping a dataset from a Hilbert space of a given dimension to a Hilbert space of a different dimension, the method comprising obtaining a dataset, for each data sample of the dataset, for a plurality of episodes, generating an encoded sample; configuring an adiabatic quantum device by embedding each encoded sample into a q-body Hamiltonian H representative of an adiabatic quantum device, causing the adiabatic quantum device to evolve from an initial state to a final state; and performing a projective measurement along z axis at the final state to determine the value of each qubit; generating a corresponding binary vector representative of the given data sample in a transformed Hilbert space using the determined value of each qubit at each episode and providing a mapped dataset comprising each of the generated corresponding binary vectors.

  • Publication number: 20210279260
    Abstract: A method and a system are disclosed for identifying at least one community, the method comprising providing an indication of a graph, the graph comprising a plurality of nodes and edges, wherein each node is representative of a given element and each edge is representative of a relationship between two given elements; providing a metric indicative of an underlying community detection algorithm; obtaining an indication of an upper bound value for a given maximum number of communities to identify; encoding each node using a one-hot encoding method and the indication of an upper bound value; generating a quadratic unconstrained binary optimization problem using the metric and the encoded nodes; providing the generated quadratic unconstrained binary optimization problem to an optimization oracle and obtaining a solution.

  • Patent number: 4918652
    Abstract: The invention is a Clock for synchronizing operations within a high-speed, distributed data processing network. The clock is actually a distributed system comprising a Central Clock and multiple Site Clock Interface Units (SCIU's) which are connected by means of a fiber optic star network and which operate under control of separate clock software. The presently preferred embodiment is as a part of the flight simulation system now in current use at the National Aeronautics and Space Administration (NASA) Langley Research Center (LaRC), Hampton, Va.
