Latest Patents

William S. Chan holds a patent for an imaging flame detection system. This system is designed to detect flames of fires while minimizing false alarms. It utilizes continuous imaging and pattern recognition of infrared (IR) images from a protected area under surveillance. The system employs a Silicon (Si) Charge-Coupled-Device (CCD) array to capture IR images, which are filtered through a narrow band IR filter centered at 1,140 nm wavelength. This filtering process helps eliminate false alarms caused by background sources. The system then digitizes and thresholds these images into binarized forms for pattern recognition. By forming blobs of suspect flames and extracting characteristic parameters, the system can statistically evaluate these blobs. It matches the parameters with those stored in a database to determine whether to declare a flame or a false alarm. When a flame is confirmed, the system automatically activates a warning for suppressant release to extinguish the fire.
