Publication number: 20220261297Abstract: 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.Type: ApplicationFiled: February 12, 2021Publication date: August 18, 2022Inventors: Xu LIU, Steve Chun-Hao HU, Abhishank SAHU, Yingji JU, Gunter LEEB, Jose FERNANDEZ, Swadhin Ajay THAKKAR, William Edward MIAO, Sravanthi PEREDDY, Jordan Robert FITZGIBBON, Raveena DAYANI

Two-dimensional antenna array, one-dimensional antenna array and single differential feeding antenna
Patent number: 9614291Abstract: 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.Type: GrantFiled: September 4, 2015Date of Patent: April 4, 2017Assignee: U&U ENGINEERING INC.Inventors: Chun-Hao Hu, Chi-Ho Chang, Yo-Sheng Lin, Ping-Chang Tsao -
