Patent number: 11378544Abstract: A biosensor for base calling is provided. The biosensor comprises a sampling device, which includes a sample surface that has an array of pixel areas and a solid-state imager that has an array of sensors. Each sensor generates pixel signals in each base calling cycle. Each pixel signal represents light gathered in one base calling cycle from one or more clusters in a corresponding pixel area of the sample surface. The biosensor further comprises a signal processor configured for connection to the sampling device. The signal processor receives and processes the pixel signals from the sensors for base calling in a base calling cycle, and uses the pixel signals from fewer sensors than a number of clusters base called in the base calling cycle. The pixel signals from the fewer sensors include at least one pixel signal representing light gathered from at least two clusters in the corresponding pixel area.Type: GrantFiled: January 7, 2019Date of Patent: July 5, 2022Assignee: Illumina, Inc.Inventors: Dietrich Dehlinger, Ali Agah, Tracy Helen Fung, Emrah Kostem

Patent number: 11294058Abstract: A flash LIDAR apparatus includes emitter units configured to emit optical signals over a field of view, and detector pixels configured to output detection signals responsive to light representing the optical signals incident thereon. The detection signals correspond to respective phase offsets relative to a frequency of the optical signals. A circuit is configured to determine component measurements corresponding to the respective phase offsets from the detection signals, and calculate a distance of a target from which the light was reflected based on the detection signals. The distance is corrected for motion of the target based on subsets of the component measurements.Type: GrantFiled: April 8, 2020Date of Patent: April 5, 2022Inventors: Dietrich Dehlinger, Hod Finkelstein
