  • Patent number: 12019625
    Abstract: Various embodiments are generally directed to techniques for automated generation of database queries. Techniques described herein may provide an automated database query generation method and system that provides a graphical user interface with one or more user interface items representing records within a database stored on a non-transitory computer-readable storage medium of a server. The server may receive an input from a graphical user interface, the input selecting one or more of the user interface elements. A processor of the server may configure the display of an indication within the graphical user interface that the one or more of the user interface elements has been selected. The processor of the server may automatically generate one or more queries to the database based upon the received input.

  • Patent number: 11733098
    Abstract: A silicon Fourier transform spectrometer and an optical spectrum reconstruction method are disclosed. The spectrometer includes a waveguide input coupler, cascaded optical switches, unbalanced subwavelength grating (SWG) waveguide pairs, and a germanium silicon detector, where the cascaded optical switches are connected through unbalanced SWG waveguide pairs. The state of the optical switches are adjusted to digitally configure the optical path, so as to constitute a series of unbalanced Mach-Zehnder interferometer (MZI) arrays with different optical path differences, to realize a Fourier transform spectrometer based on spatial heterodyne. The optical spectrum is reconstructed by using a compressed sensing algorithm.
