Power Sharing Methods and Systems for Use With a Capture Device

Abstract:

Systems and methods for charging a rechargeable battery of a barcode reader are provided. In one example, two connectors of an interface device are connected to two corresponding host-provided power sources, each with limited output current capacity. The output currents of the host-provided power sources are combined to provide a combined current to a power storage unit of the interface device, which provides power to a wireless power transmitter of the interface device. The wireless power transmitter wirelessly transmits the power received from the power storage unit to a wireless power receiver of the barcode reader that provides power to a rechargeable battery of the barcode reader. In other examples, the interface device does not include a power storage unit, and the battery chargers are replaced with current limiters (e.g., current limited switches with reverse protection).
