Publication number: 20100142822Abstract: A method and system for detecting flames are provided. The flame detection method based on image processing techniques performs the following steps to detecting flames. It first finds one or more bright objects in the images that are captured from videos. A flickering state of a bright object is then determined. To verify the existence of a flame, additionally subsequent images from the instant that a bright object first appears are utilized and the similar steps are applied to them. Finally a flame could be detected if the analyzed results are positive after the aforementioned steps have been performed.Type: ApplicationFiled: November 17, 2009Publication date: June 10, 2010Applicant: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Hsin-Sen CHU, Chung-Hsien LU, Shen-Kuen CHANG, Hao-Ting CHAO, Cheng-Wei WANG, Kun-Lin HUANG

Publication number: 20070142886Abstract: Disclosed is a means and method for the treatment of migraine headaches and other disorders of the human body by the application of one or more intense magnetic pulses. By placing an intense magnetic field pulse(s) onto a certain region of the brain, an electrical current can be generated in the cerebral cortex that can stop a migraine headache in some patients or at least decrease its severity. The device to perform this function can be called a “magnetic pulser system.” This system can be made in one piece and powered by plugging into a household or automobile receptacle or from a battery. The pulser system uses capacitors that are first charged to a high voltage and then discharged into a coil that creates the intense magnetic pulse. Both visual and auditory signals can be provided by the pulser system to assist the patient in using the device.Type: ApplicationFiled: December 19, 2005Publication date: June 21, 2007Inventors: Robert Fischell, Scott Fischell, David Fischell, Emily Ma, Kuen Chang, Dave Vondle, Benjamin Pless
