This invention provides a circuit and a method for generating a bandgap reference voltage for integrated circuits. The inspection site clamps a flexible eddy current sensor array to the curved material surface, scans the array over the surface, records the sensor position. According to one aspect, tags are embedded into syndication feeds that may be made available for distribution by an online media store to facilitate the management of podcasts. The identified flow may be dynamically assigning to an available flow queue when it is determined that a flow queue has not been assigned to the identified flow.
