International Classification:

G06F 1300

US Classification:

395750

Abstract:

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.

Abstract:

A RF data communications system for remotely collecting data and a method of developing applications for such a system are provided. The RF data communications system preferably has a first computer including at least a first microprocessor, a first screen display, and a first data screen file positioned representing a first predetermined screen display format. A first RF data transceiver is positioned in electrical communication with the first microprocessor of the first computer for transmitting and receiving RF data, and a second RF data transceiver is positioned remote from the first RF data transceiver and the first computer for transmitting RF data to and receiving RF data from the first RF data transceiver. A second computer is positioned in electrical communication with the second RF data transceiver and remote from the first computer. The second computer preferably is arranged for collecting data remote from the first computer and includes at least a data sensor, a second microprocessor, a second screen display, and a second data screen file representing a second predetermined screen display format.
