Flywheel energy storage (FES) provides high density storage. Traditional systems relied on mechanical bearings. Bearings can be replaced by electromagnetic variations. Modern FES systems levitate inertial mass on electromagnetic cushions. Levitation consumes energy, so FES systems are confined to short-term power quality applications. An FES system that uses passive levitation is presented. Passive...
Dynamic programming is a powerful method for solving energy minimisation problems in computer vision, for example stereo disparity computations. While it may be desirable to implement this algorithm in hardware to achieve frame-rate processing, a naı¨ve implementation may fail to meet timing requirements. In this paper, the structure of the cost matrix is examined to provide improved methods of hardware...
