Methods and Systems for Communicating Data on an Electronic Device
A method of receiving data from a first component of an imaging device, by a second component of the imaging device, comprising: determining, by the second component, indirect data from a feature of a communication between the first and second components of the imaging device, wherein the communication is a data line communication. A supply item for an imaging device configured to receive data from a first component of the imaging device by determining indirect data from a feature of a communication between the first component of the imaging device and the supply item, wherein the communication is a data line. Alternatively, the supply item is configured to send data to the first component of the imaging device by converting indirect data into a feature of a communication and causing the communication to occur between the first component and the supply item, wherein the communication is a data line.

9 . The method of claim 2 , wherein measuring the property of the feature comprises timing.
10 . The method of claim 9 , wherein the property is a time period between receiving two transmissions and timing comprises measuring the length of the time period.
11 . The method of claim 9 , wherein the property is a time period over which a type of transmission is received and timing comprises measuring the length of the time period.
12 . The method of claim 1 , wherein receiving data further comprises using the indirect data to determine functionality to be performed by the second component.
13 . The method of claim 12 , wherein the functionality to be performed by the second component is an algorithm and the method further comprises determining a property of the algorithm via a look-up table.
14 . The method of claim 12 , wherein using the indirect data to determine functionality to be performed by the second component comprises using the indirect data as an index into direct data sent in the communication.
15 . The method of claim 12 , wherein using the indirect data to determine functionality to be performed by the second component comprises using the indirect data as an input to a computation on direct data sent in the communication.
16 . A method of communicating data between a first and a second component of an imaging device comprising:
sending the data by the first component of the imaging device, to the second component of the imaging device by converting, by the first component, the data into a feature of a communication and causing the communication to occur between the first and second components, wherein the communication is a data line communication, and
receiving the data from the first component of the imaging device, by the second component of the imaging device according to the method of claim 1 .
17 . A supply item for an imaging device, the supply item configured to, when installed in the imaging device:
receive data from a first component of the imaging device by:
determining indirect data from a feature of a communication between the first component of the imaging device and the supply item, wherein the communication is a data line communication, and/or
send data to the first component of the imaging device by:
