Wireless scanner system, head and method
First Claim
1. A scanning system for a web comprising:
- a scanner head that scans along a scanning path back and forth across said web and that comprises at least one electronic unit and an electrical energy storage device that provides operating power to said electronic unit; and
a charging station disposed to provide electrical energy to charge said electrical energy storage device with enough energy to provide said operating power to said electronic unit for at least one trip of said scanner head across said web, wherein said scanner head docks with said charging station to receive said electrical energy to charge said electrical energy storage device at an end of said scanning path.

Abstract
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.
