Abstract
Official abstract text for this publication.
In a method for operating a portable electronic device a recharge process for recharging a rechargeable energy storage of the portable electronic device is detected. A heater is activated for heating a sensitive layer of a chemical sensor contained in the portable electronic device subject to the detection of the recharge process.
First claim
Opening claim text (preview).
The invention claimed is: 1. Method for operating a portable electronic device, comprising detecting a recharge process for recharging a rechargeable energy storage of the portable electronic device, and activating a heater for heating a sensitive layer of a chemical sensor contained in the portable electronic device, wherein the heater is activated subject to the detection of the recharge process and subject to a period of time elapsed since the last time the heater has been activated in response to a recharge process. 2. Method according to claim 1 , wherein the heater is deactivated in response to a termination of the recharge process. 3. Method according to claim 1 , wherein the heater is activated in response to the detection of the recharge process if the period of time elapsed since the last time the heater has been activated in response to a recharge process exceeds a first threshold. 4. Method according to claim 1 , wherein readings are taken by the chemical sensor while the heater is activated in response to the detection of a recharge process, wherein a deviation is determined between a current sensor reading and one or more of previous sensor readings, and wherein the heater is deactivated if the deviation is below a first threshold. 5. Method according to claim 4 , wherein the readings are taken periodically. 6. Computer-readable storage medium having stored thereon instructions for implementing a method according to claim 1 when being executed on a control unit. 7. Method for operating a portable electronic device, comprising detecting a recharge process for recharging a rechargeable energy storage of the portable electronic device, and activating a heater for heating a sensitive layer of a chemical sensor contained in the portable electronic device, wherein the heater is activated subject to the detection of the recharge process and subject to a period of time elapsed since the last time the heater has been activated for conducting a measurement. 8. Method according to claim 7 , wherein the heater is activated in response to the detection of the recharge process if the period of time elapsed since the last time the heater has been activated for conducting a measurement exceeds a first threshold. 9. Method according to claim 7 , wherein the heater is deactivated in response to a termination of the recharge process. 10. Method according to claim 7 , wherein readings are taken by the chemical sensor while the heater is activated in response to the detection of a recharge process, wherein a deviation is determined between a current sensor reading and one or more of previous sensor readings, and wherein the heater is deactivated if the deviation is below a first threshold. 11. Method according to claim 10 , wherein the readings are taken periodically.
