System and apparatus for determining ambient temperatures for a fluid analyte system
First Claim
1. A portable meter configured to rapidly determine ambient temperature, the portable meter comprising:
- a housing defining an interior space and an area for receiving a fluid sample;
a first processing unit and a first temperature sensor disposed within said interior space of said housing; and
a second temperature sensor disposed on said housing; and
said first processing unit or another processing unit being configured to;
determine a first temperature value from temperature data received from said first temperature sensor,apply a variable current to a temperature-adjustment source such that said second temperature sensor is adjusted to a predetermined steady-state temperature value different from said first temperature value, anddetermine an ambient temperature of an exterior space of said housing based on said applied variable current, said pre-determined steady-state temperature value, and said received first temperature value.

Abstract
A system and method for rapidly determining ambient temperature in a fluid-analyte meter. The meter includes a housing defining an interior space and an area for receiving a fluid sample. A processor and a first temperature sensor are disposed within the interior space of said the housing. A second temperature sensor is disposed on the housing. One or more processors are configured to determine a first temperature value from temperature data received from the first temperature sensor. The processor(s) are also configured to apply a variable current to a temperature-adjustment source such that the second temperature sensor is adjusted to a predetermined steady-state temperature value different from the first temperature value. The processor(s) are further configured to determine an ambient temperature of an exterior space of the housing based on the applied variable current, pre-determined steady-state temperature, and received first temperature values.
