Abstract
A mobile electronic device includes an earphone/microphone port, an I/O circuit to receive a modulated data signal from data input devices via the earphone/microphone port, and a processor unit programmed to extract data from the modulated data signal. The processor unit (or the I/O circuit) detects connection of a device to an earphone/microphone connector of the mobile electronic device and determines whether the connected device is a data input device. If the connected device is a data input device, the processor unit is programmed to extract data from modulated data signals generated by data input device.
Claims39
A method for receiving data in a mobile electronic device from a data input device, the method comprising:
- detecting connection of a device to an earphone/microphone connector of the mobile electronic device;
- determining whether the connected device is a data input device;
- and
- extracting data from a modulated data signal generated by data input device in response to determining the connected device is a data input device.
A machine-readable medium having instructions for performing operations comprising:
- detecting connection of a device to an earphone/microphone connector of a mobile electronic device;
- determining whether the connected device is a data input device;
- and
- extracting data from a modulated data signal generated by data input device in response to determining the connected device is a data input device.
An apparatus for receiving data in a mobile electronic device from an external data input device, the apparatus comprising:
- an earphone/microphone port coupleable to a data input device;
- an input circuit to receive a modulated data signal from the data input device via the earphone/microphone port;
- and
- a processor unit programmed to extract data from the modulated data signal.
An apparatus for receiving data in a mobile electronic device from an external data input device via an earphone/microphone port, the apparatus comprising:
- means for receiving a modulated data signal from the data input device via the earphone/microphone port;
- means for extracting data from the modulated data signal.
A system for receiving data in a mobile electronic device from an external data input device via an earphone/microphone port of the mobile electronic device, the system comprising:
