Patent Searching and Data


Title:
検体センサと関連付けられている温度を決定するべく構成されたセンサシステム
Document Type and Number:
Japanese Patent JP6466506
Kind Code:
B2
Abstract:
Systems and methods for processing sensor data and self-calibration are provided. In some embodiments, systems and methods are provided which are capable of calibrating a continuous analyte sensor based on an initial sensitivity, and then continuously performing self-calibration without using, or with reduced use of, reference measurements. In certain embodiments, a sensitivity 110 of the analyte sensor is determined by applying an estimative algorithm 120 that is a function of certain parameters. Also described herein are systems and methods for determining a property of an analyte sensor using a stimulus signal. The sensor property can be used to compensate sensor data for sensitivity drift, or determine another property associated with the sensor, such as temperature, sensor membrane damage, moisture ingress in sensor electronics, and scaling factors.
