 High-speed imagers are required for industrial applications, traffic monitoring, robotics and unmanned vehicles, movie-making, etc. Many of these applications call also for large spatial resolution, high sensitivity and the ability to detect images with large intra-frame dynamic range. This paper reports a CIS intelligent digital image sensor with(More)
During circumferential pulmonary vein isolation, radiofrequency lesions are created in the transition zone between the left atrium and the pulmonary veins, outside the ostia, to avoid stenosis. Three-dimensional impedance maps were constructed for 25 patients with paroxysmal atrial fibrillation. In the first 15 patients, impedance was measured inside the(More)
This paper presents a survey of the characteristics of a vision system implemented in a reconfigurable/programmable chip (FPGA). System limitations and performance have been evaluated in order to derive specifications and constraints for further vision system synthesis. The system hereby reported has a conventional architecture. It consists in a central(More)
