Systems and Methods for Predicting Ambient Temperature in a Fluid Analyte Meter
First Claim
1. A meter configured to determine an analyte concentration of a fluid sample, the meter comprising:
- a housing;
a temperature sensor disposed within the housing;
a processor configured to predict a temperature value that approximates an ambient temperature outside of the housing, the predicted temperature value based on a preceding predicted temperature value and received prior temperature data that is at least partially associated with the temperature sensor such that the predicted temperature value is set equal to the preceding predicted temperature value if a recently received prior temperature value (i) is within predetermined upper and lower temperature thresholds, and (ii) exceeds the preceding predicted temperature value.

Abstract
A system for a meter configured to determine an analyte concentration of a fluid sample includes a housing and a temperature sensor disposed within the housing. The system also includes a processor configured to receive temperature data from the temperature sensor upon the meter entering one of a charge state and a discharge state. The processor is further configured to predict a temperature value that approximates the ambient temperature outside of the housing. The predicted temperature value is based on historical temperature data received from the temperature sensor such that the predicted temperature value remains constant if a recently received temperature value remains within predetermined upper and lower temperature thresholds and the recently received temperature value exceeds the at least one predicted temperature value.

57. A method for predicting a temperature value in a meter configured for determining an analyte concentration of a fluid sample, the method comprising:
-
receiving temperature data obtained from one or more temperature sensors; storing the temperature data in one or more memories associated with a processor; upon the meter entering at least one of a charge state or a discharge state, predicting via the processor a temperature value that approximates an ambient temperature outside of a housing associated with the meter, the predicted temperature value based on a preceding predicted temperature value and the received temperature data, wherein the predicted temperature value is equal to one of the following; (i) the preceding predicted temperature value if a recently received temperature value is within predetermined upper and lower temperature thresholds and if the recently received temperature value exceeds the preceding predicted temperature value, (ii) the recently received temperature value if the recently received temperature value is outside the predetermined upper and lower temperature thresholds, and (iii) the recently received temperature value if the recently received temperature value is less than the preceding predicted temperature value. - View Dependent Claims (58, 59, 60, 61, 62)
