Accessory interface system
First Claim
1. An accessory and a wireless communication device configured to detect the type of accessory connected to the wireless communication device comprising:
- an accessory comprising;
two or more outputs configured to connect to the wireless communication device;
a signal source configured to connect to at least one of the two or more outputs, the two or more outputs arranged to generate a line voltage pattern; and
a memory configured to store more than about 1 kilobits of predefined control data, the control data including software code, software patches, or software updates;
a wireless communication device comprising;
two or more inputs configured to receive the line voltage pattern from the accessory;
a processor configured to;
analyze the line voltage pattern to determine a type of accessory connected to the wireless communication device;
initiate accessory interaction based on the analysis; and
use the control data to operate the accessory.

Abstract
A method and apparatus for interfacing an electronic device and an accessory is disclosed. In one embodiment the accessory comprises a communication device. To achieve desired operation of the accessory with the communication device the accessory includes memory configured to store control data or other interface data. Storing the control data in the accessory insures that the communication device has access to the control data tailored to the accessory hardware. Storing the control data on the accessory also creates independence between the accessory an the electronic device such that accessory may be introduced to market after the communication device is purchased. In one embodiment the control data is downloaded to the communication device for use by the communication device. The communication device may permanently store the control data such that the download process may be avoided during subsequent use of the accessory with the communication device.

13. A method for detecting a category of an accessory connected to a wireless communication device:
-
storing predefined control data in the accessory, the control data being software code, software patches, or software updates; providing a wireless communication device with two or more inputs; monitoring the two or more inputs for a line voltage pattern; comparing the line voltage pattern to a predetermined pattern; determining, responsive to the comparing, that the accessory has the software code, the software update, or the software patch in the accessory memory; and transferring the control data to the wireless communications device for operating the accessory by the wireless communication device. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)
