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.
Claims27
A method comprising:
- receiving information indicating a geographical area;
- with reference to at least a portion of the information indicating a geographical area, selecting a machine-readable indicia detector that corresponds to the information indicating a geographical area;
- using one or more electronic processors, processing machine-readable indicia with the selected machine-readable indicia detector to obtain a plural-bit message;
- and
- carrying out an action using the plural-bit message.
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.
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.
The cell phone of 20 in which the different detectors are distinguished from one another based on different detection keys.
