  • Publication number: 20230304945
    Abstract: A compact, low-power, high image rejection sideband separation receiver is provided. The receiver observes an input radio frequency (RF) signal of multiple spectral lines (spectral observation), then downconverts the signals to intermediate frequency (IF), and then separates the signals to be observed simultaneously in multiple channels. An embodiment is used to observe a signal (G-band) with two spectral lines and utilizes a two stage Weaver architecture to downconvert the signal's frequency, including a combination of mixers in the second stage that achieves the separation of two different channels.

  • Publication number: 20230277976
    Abstract: A carbon dioxide collection system having a release enclosure, a capture structure, and a chimney is disclosed. The release enclosure includes a sorbent regeneration system. The capture structure includes a sorbent material, and is movable between collection and release configurations. The chimney is shaped such that an airflow upward through the chimney is created. The chimney is positioned above the release enclosure such that the airflow passes through the capture structure while in the collection configuration. The collection configuration includes the capture structure being elevated above the release enclosure so the sorbent material is exposed to the airflow generated by the chimney, allowing the sorbent material to capture CO2 from the airflow.

  • Publication number: 20230269377
    Abstract: A system defining a visual sensing pipeline architecture flexibly allows application developers to dynamically adapt the spatial resolution and update rate of different “rhythmic pixel encoding regions” in a scene. The system ingests pixel streams with raster-scan pixel read-out patterns, but only encodes relevant pixels prior to storing them in memory. The system includes streaming hardware to decode the stored rhythmic pixel encoding region stream into traditional frame-based representations to feed into standard computer vision algorithms.

  • Publication number: 20230215961
    Abstract: Contacts for solar cells and other optoelectronic devices are provided. Embodiments described herein take advantage of the surface Fermi level pinning effect to build an electrical field inside of a semiconductor to extract or inject carriers for solar cells, photodetectors, and light-emitting device applications. For example, n-type or p-type two-dimensional (2D) materials can be used in contact with an n-type semiconductor to form a “p-region” so that a p-n junction, or an i-n or n-n+ junction can be constructed. Similarly, n-type or p-type 2D materials can be used in contact with a p-type semiconductor to form an “n-region” so that an n-p junction, or an i-p or p-p+ junction can be constructed. These structures can provide sufficiently high electrical field inside the semiconductor to extract photogenerated carriers in solar cells and photodetectors or inject minority carriers for light-emitting devices.
