An apparatus includes one or more magnetic cores collectively having an inner leg located between two outer legs. The legs are coupled to one or more connecting portions. The apparatus also includes one or more conductive coils wound around the inner leg. The one or more magnetic cores and the one or more conductive coils are configured to generate substantially balanced magnetic fluxes when the conductive coil is energized. Also, the one or more magnetic cores and the one or more conductive coils are configured so that heat created by currents induced in the roll by the magnetic fluxes produces a steady state thermal profile on a surface of the roll. The steady state thermal profile has one peak that falls within a control zone associated with the roll. The one or more magnetic cores could include a single magnetic core or multiple magnetic cores.

System, apparatus, and method for induction heating using flux-balanced induction heating workcoil

A scanning system includes a scanner head that scans along a scan path back and forth across a web. The scanner head is wireless and gets its operating power from an on-board electrical energy storage device, such as a battery or a capacitor. The scanner head docks to a charging station that provides electrical energy to the scanner head for charging the electrical energy storage device. The electrical energy is transferred by an energy coupling relationship that is magnetic field, electric field or direct electrical connection. The magnetic field relationship uses a charging circuit coil and core that mates with scanner head coil and core when the scanner head is docked. The electric field relationship uses a charging side electrically conductive plate that mates with a scanner head electrically conductive plate when the scanner head is docked.
