Methods comprising applying a first analyte point measurement filter comprising: receiving, from an in vivo analyte sensor, at least a first, second, and third uncompensated analyte measurement at a first, second and third reference time; determining a first scaled rate-of-change by multiplying a first weighting coefficient and a first rate-of-change, the first rate-of-change computed between the first uncompensated analyte measurement at the first initial reference time to the second uncompensated analyte measurement at the first prior reference time; determining a second scaled rate-of-change by multiplying a second weighting coefficient and a second rate-of-change, the second rate-of-change computed between the first uncompensated analyte measurement at the first initial reference time to the third uncompensated analyte measurement at the second prior reference time; and calculating a first filter lag-compensated point measurement based on the sum of the first uncompensated analyte measurement, the first scaled rate-of-change, and the second scaled rate-of-change.

Methods of lag-compensation for analyte measurements, and devices related thereto

Methods of compensating for ambient temperature using temperature sensors, the method comprising: sampling at a first sampling rate, with a processor, first temperature measurements from a first temperature sensor on an on-body sensor. Then determining, with a processor, first ambient-compensated temperatures from the first temperature measurements; and determining, with a processor, final ambient-compensated temperatures by applying a correction gain or factor to the first ambient-compensated temperatures. Wherein the correction gain or factor changes value at a slower rate than the sampling rate.

Temperature-compensated analyte monitoring devices, systems, and methods thereof

In some aspects, methods of lag compensation of analyte measurements are provided. Methods of lag-compensation are provided for analyte point measurements and/or for analyte rate-of-change measurements. The methods include receiving a series of uncompensated analyte measurements and determining parameter values for analyte point and/or rate-of-change estimates based on reference analyte measurements. The analyte rate-of-change estimate is based on a sum of a plurality of scaled rates-of-changes. The analyte point estimate is based on a sum of an analyte point and a sum of a plurality of scaled rates-of-changes. Devices related to the methods are also provided.

Methods of compensating for ambient temperature using a single temperature sensor, the method comprising detecting a first temperature measurement from a temperature sensor; and determining, with a processor, an ambient-compensated temperature from the first temperature measurement using an offset term. The method may also include receiving a sensor signal from an in vivo analyte sensor; and determining, with a processor, a temperature-compensated analyte sensor signal with the ambient-compensated temperature.

Methods, devices and systems related providing accurate glucose levels in view of temperatures that may adversely affect glucose value.
