ANALYTE MONITORING SYSTEM CAPABLE OF DETECTING AND PROVIDING PROTECTION AGAINST SIGNAL NOISE GENERATED BY EXTERNAL SYSTEMS THAT MAY AFFECT THE MONITORING SYSTEM

摘要

An analyte monitoring system includes a biosensor for detecting an analyte concentration in blood. The monitoring system includes a sensor for sensing whether a tool or other piece of equipment is producing electrical noise that may affect operation of the biosensor. If such electrical noise is detected, the system isolates the biosensor during the period of detected operation of the other tool or equipment. In some embodiments, the system measures both signal noise in and temperature of the environment surrounding the biosensor to determine whether another tool or other piece of equipment is currently in operation. The system may also include an auxiliary power source to maintain the biosensor in a biased state during the period when the biosensor is placed in isolation.
