  • Patent number: 10859212
    Abstract: Methods, systems, and techniques for determining whether an acoustic event has occurred along a fluid conduit having acoustic sensors positioned therealong. The method uses a processor to, for each of the sensors, determine a predicted acoustic signal using one or more past acoustic signals measured prior to measuring a measured acoustic signal using the sensor; determine a prediction error between the measured acoustic signal and the predicted acoustic signal; from the prediction error, determine a power estimate of an acoustic source located along a longitudinal segment of the fluid conduit overlapping the sensor; and determine whether the power estimate of the acoustic source exceeds an event threshold for the sensor. When the power estimate of at least one of the acoustic sources exceeds the event threshold, the processor attributes the acoustic event to one of the sensors for which the power estimate of the acoustic source exceeds the event threshold.

  • Patent number: 10838155
    Abstract: The optical fiber coupler array can be capable of providing a low-loss, high-coupling coefficient interface with high accuracy and easy alignment between a plurality of optical fibers (or other optical devices) with a first channel-to-channel spacing, and an optical device having a plurality of closely-spaced waveguide interfaces with a second channel-to-channel spacing, where each end of the optical fiber coupler array can be configurable to have different channel-to-channel spacing, each matched to a corresponding one of the first and second channel-to-channel spacing. Advantageously, the refractive indices and sizes of both inner and outer core, and/or other characteristics of vanishing core waveguides in the optical coupler array can be configured to reduce the back reflection for light propagating from the plurality of the optical fibers at the coupler first end to the optical device at the coupler second end, and/or vice versa.

  • Patent number: 10768371
    Abstract: A display assembly presented herein includes an inset display, a peripheral display, and a multiplexing optical assembly (MOA). The inset display has a first resolution and emits image light of a first polarization. The peripheral display has a second resolution and emits image light of a second polarization. The MOA receives the image light of the first polarization and the image light of the second polarization. The MOA then transforms the image light of the first polarization into a first portion of image light of a third polarization, and transforms the image light of the second polarization into a second portion of image light of the third polarization. The MOA directs the first portion of image light and the second portion of image light toward an eye-box. The display assembly can be implemented as a component of a head-mounted display of an artificial reality system.
