Patent ID: 7157932

Claim:
An input/output (I/O) system for generating an output signal from an input signal, the I/O system comprising: an I/O device adapted to receive the input signal and generate the output signal based on the input signal, wherein: the generation of the output signal by the I/O device is affected by one or more environmental conditions associated with the I/O device; the I/O device is further adapted to receive an I/O-device control signal corresponding to the one or more environmental conditions; and the I/O device is adapted to adjust the generation of the output signal based on the I/O-device control signal; a condition sensor adapted to generate a sensed condition signal that characterizes the one or more environmental conditions; and a controller adapted to (i) receive the sensed condition signal from the condition sensor and a programmable offset value and (ii) modify the sensed condition signal based on the programmable offset value to generate and provide the I/O-device control signal to the I/O device, wherein the controller is adapted to; map the sensed condition signal to an index value; adjust the index value based on the programmable offset value to generate an adjusted index value; and map the adjusted index value to the I/O-device control signal.
