Abstract: A flame detection system is disclosed. The flame detection system comprises one or more sensors to detect one or more targets within a field of view (FOV). Further, at least one imaging device is installed based on a distance between one or more sensors, one or more targets, and the FOV. The at least one imaging device is configured to capture one or more real time images of one or more targets within the FOV. Further, one or more processors are communicatively coupled to one or more sensors and at least one imaging device. The one or more processors are configured to receive one or more real time images, compare one or more real time images with at least one reference image and determine a misalignment information, obstacle information, or misalignment and obstacle information within the FOV based at least on comparison.

Abstract: An imaging-based flame detection system is disclosed. The imaging-based flame detection system comprises at least one image capturing device to capture one or more images in a field of view (FOV). Each of the one or more images comprises an array of pixels. Further, one or more sensors are communicatively coupled to the at least one image capturing device and configured to analyze the FOV of captured one or more images. Further, the one or more processors are communicatively coupled to at least one image capturing device and one or more sensors. The one or more processors are configured to receive the one or more captured images; associate at least a portion of the array of pixels with a corresponding one or more zones; associate the corresponding one or more zones with a criticality level and determine a status based at least on the analyzed FOV and the criticality level.

Abstract: A flame detection system is disclosed. The flame detection system comprises at least one monitoring device comprising at least one primary flame detector configured to detect one or more infrared (IR) signals from a monitoring zone, and at least one secondary flame detector configured to detect one or more IR signals from a flame zone. Further, one or more processors are communicatively coupled to the at least one monitoring device. The one or more processors are configured to receive the detected one or more IR signals from the monitoring zone and the flame zone, correlate the one or more IR signals from the monitoring zone with the one or more IR signals from the flame zone based at least on time and frequency domain of the detected one or more IR signals, and determine a status of flame within the monitoring zone based at least on the correlation.

Abstract: An edge coupler for coupling a light beam (e.g., a laser beam) into a waveguide comprises a first waveguide section characterized by a first thickness and a first constant width, a second waveguide section physically coupled to the first waveguide section and characterized by the first thickness and a gradually decreasing width, and a third waveguide section partially overlapping with the second waveguide section at an overlap region, the third waveguide section characterized by a gradually increasing width and a second thickness different from (e.g., greater than) the first thickness. In some embodiments, a surface (e.g., the top or bottom surface) of the second waveguide section and a surface (e.g., the top or bottom surface) of the third waveguide section are on a same plane.
