Patent ID: 8788077

Claim:
A control device configurable to couple to a plurality of devices having different control functions comprising: a touch sensitive display reconfigurable for the different control functions of the plurality of devices; and a processor coupled to the touch sensitive display, the processor including a plurality of processing algorithms, the processor configured to receive at least one of the control functions and additional information from among the plurality of devices, the processor configured to selectably process the additional information using at least one of the processing algorithms based on the respective device and to control the touch sensitive display such that the at least one control function and the selectably processed additional information peculiar to the respective device of the plurality of devices are presented on the touch sensitive display, where the processor, responsive to an indication by the touch sensitive display, generates at least one control signal, where the processor sends the at least one control signal to the corresponding device among the plurality of devices being controlled and sends the selectably processed additional information to at least one of the plurality of devices, and where the additional information received from among the plurality of devices includes a signal generated from at least one of the plurality of processing algorithms including an audio signal processing algorithm to analyze an audio signal to determine a sound pressure level dosage as a percentage of an accumulated dose or as a time remaining value before a threshold shift occurs.
