Patent ID: 8777852

Claim:
An implantable sensing system comprising: a sensor for sensing a biological parameter; a processor connected to the sensor for processing the parameter; and a drug delivery unit connected to the processor for responding to the processor based on the parameter; wherein the processor is programmed to adjust an output of the sensor by: adjusting a calibration curve, wherein the adjusting of the calibration curve includes: compiling an array of data relating to the sensor; adjusting a sensor parameter, wherein the sensor parameter affects the calibration curve, a first time based on data in the array, whereby the calibration curve is adjusted a first time; adjusting the shape of the calibration curve, whereby the calibration curve is adjusted a second time; and after adjusting the shape of the calibration curve, adjusting the sensor parameter a second time based on the data in the array, whereby the calibration curve is adjusted a third time; and calculating an adjusted sensor output based on the adjusted calibration curve, wherein the calculating of the adjusted sensor output is performed only after the calibration curve has been adjusted a third time.
