  • Patent number: 10735886
    Abstract: A method of generating binaural headphone playback signals given multiple audio source signals with an associated metadata and binaural room impulse response (BRIR) database, wherein the multiple audio source signals can be channel-based, object-based, or a mixture of both signals. The method includes grouping the multiple audio source signals according to positions of the audio sources in a hierarchical manner, and parameterizing BRIR to be used for rendering. The method also includes dividing each audio source signal to be rendered into a number of blocks and frames, averaging the parameterized BRIR sequences identified with a hierarchically grouping result, and downmixing the divided audio source signals identified with the hierarchically grouping result.

  • Publication number: 20200166440
    Abstract: An embodiment of the invention relates to a device for detecting an analyte in a sample. The device comprises a fluidic network and an integrated circuitry component. The fluidic network comprises a sample zone, a cleaning zone and a detection zone. The fluidic network contains a magnetic particle and/or a signal particle. A sample containing an analyte is introduced, and the analyte interacts with the magnetic particle and/or the signal particle through affinity agents. A microcoil array or a mechanically movable permanent magnet is functionally coupled to the fluidic network, which are activatable to generate a magnetic field within a portion of the fluidic network, and move the magnetic particle from the sample zone to the detection zone. A detection element is present which detects optical or electrical signals from the signal particle, thus indicating the presence of the analyte.

  • Patent number: 10663633
    Abstract: A method for performing DBO measurements utilizing apertures having a single pole includes using a first aperture plate to measure X-axis diffraction of a composite grating. In some embodiments, the first aperture plate has a first pair of radiation-transmitting regions disposed along a first diametrical axis and on opposite sides of an optical axis that is aligned with a center of the first aperture plate. Thereafter, in some embodiments, a second aperture plate, which is complementary to the first aperture plate, is used to measure Y-axis diffraction of the composite grating. By way of example, the second aperture plate has a second pair of radiation-transmitting regions disposed along a second diametrical axis and on opposite sides of the optical axis. In some cases, the second diametrical axis is substantially perpendicular to the first diametrical axis.
