摘要： A data recognition apparatus of the invention preferably has a data communication apparatus and a portable data reader adapted to communicate therewith. The portable data reader is particularly adapted to substantially extend the time period required before replacing or recharging a portable power source connected thereto. The portable data reader preferably includes a data sensor, a central processor, a display, a user interface, a transceiver, a timer, a portable power source, and a power manager. The power manager is connected in electrical communication with the portable power source, the data sensor, the central processor, the display, the user interface, and the transceiver and the central processor is connected in electrical communication with the timer. The power manager manages the amount of and timing of power supplied to the data sensor, the central processor, the display, and the transmitter and receiver responsive to command signals received from the central processor and interaction of a user with the user interface. The power manager also preferably provides at least four modes of predetermined power operation of the central processor, the display, and the user interface. A method of managing power for such a portable data reader are also included.
