Abstract
The present invention relates generally to signal processing and cell phones. One claim recites a method comprising: receiving a signal from a cell phone; determining, based at least in part on the signal, whether the cell phone is physically located in a predetermined home area; and if not in the predetermined home area, communicating a machine-readable code detector to the cell phone for use as its primary machine-readable code detector to detect machine-readable code while outside of its predetermined home area. Of course, other claims are provided too.

20. A cell phone comprising:
-
a radio-frequency transceiver; and an electronic processor programmed for; receiving information related to a current geographic area in which the cell phone is located; selecting, using at least a portion of the received information, a first detector that is associated with the current geographic area, a selected first detector being selected from a plurality of different detectors; and controlling the cell phone to employ the selected first detector to analyze a signal to obtain data there from, in which the selected first detector corresponds to the geographic area. - View Dependent Claims (22, 23, 24, 25, 26, 27)
