  • Publication number: 20220261297
    Abstract: Embodiments disclosed herein are related to implementing a near-real-time stream processing system using the same distributed file system as a batch processing system. A data container and partition files are generated according to a partition window that specifies a time range that controls when data is to be included in the partition files. The data container is scanned to determine if the partition files are within a partition lifetime window that specifies a time range that controls how long the partition files are active for processing. For each partition file within the lifetime window, processing tasks are created based on an amount of data included in the partition files. The data in the partition files is accessed and the processing tasks are performed. Information about the partition files is recorded in a configuration data store.

  • Patent number: 10416545
    Abstract: A laser projector includes a light-mixing module and a light-splitting module. The light-mixing module provides a laser beam which includes first polarized light and second polarized light. The light-splitting module includes a dichroic mirror, a half-wave plate, a phosphor wheel module, and a light-guiding rod. The dichroic mirror allows the first polarized light to pass and reflects the second polarized light. The half-wave plate receives the first polarized light which passes the dichroic mirror and converts the first polarized light into third polarized light. The phosphor wheel module receives the second polarized light reflected by the dichroic mirror, and provides a stimulated light which passes the dichroic mirror. The light-guiding rod receives the stimulated light and the third polarized light, thereby providing an illumination beam.

  • Patent number: 9614291
    Abstract: A two-dimensional antenna array has n rows of 1×m one-dimensional array and each one-dimensional array is composed of multiple single differential feeding antennas. Each single differential feeding antenna has a differential feeding structure and a microstrip antenna stripe. A longitudinal length of the microstrip antenna stripe is no longer than one wavelength in a dielectric medium, so the microstrip antenna stripe is not excited to a high-order mode. An angle of inclination of a main beam aligns with the broadside and a width of the main beam is further concentrated at elevation direction. The differential feeding structure can reduce an even mode to enhance an isolation. The one and two-dimensional antenna array is miniature by using the small single differential feeding antennas. Isolation and gain of a dual-antenna system using the two-dimensional or one-dimensional antenna arrays are further enhanced and increased if more feeding antenna arrays are used.
