Abstract

A mobile device has one or more sensors that are configured to detect the presence of fog or frost on a surface of the mobile device. A battery provides power to the mobile device. An energy transfer element, when activated, removes fog or frost from a surface of the mobile device. A programmed processor, within the mobile device, is programmed to: read one or more sensors disposed in the mobile device to determine if there is a fog or frost condition; upon detecting a fog or frost condition, activating the energy transfer element to remove fog or frost; and upon detecting an absence of the fog or frost condition, deactivating the heater energy transfer element.

Claims

1. A method of controlling fog or frost on a mobile device, comprising:

providing a programmed processor, one or more sensors, and an energy transfer element that when activated removes fog or frost within the mobile device;

the processor reading the one or more sensors disposed in the mobile device to determine if there is a fog or frost condition;

the processor, upon detecting a fog or frost condition, activating the energy transfer element to remove fog or frost; and

the processor, upon detecting an absence of the fog or frost condition, deactivating the energy transfer element.

2. The method according to claim 1, where the one or more sensors comprises a temperature sensor, and where the processor determines that there is a fog or frost condition if the temperature rises by more than a threshold Δ

T over a prescribed period of time.

3. The method according to claim 2, where the processor determines that a fog or frost condition has passed when the temperature sensor detects a temperature of a prescribed temperature T_Clear.

4. The method according to claim 2, where the value of Δ

T is adjustable.

5. The method according to claim 2, where the temperature sensor measures a temperature of a window covering a display or an imaging optics system.

6. The method according to claim 1, where the one or more sensors comprises a sensor that directly examines a surface of the mobile device to detect the presence of fog or frost.

7. The method according to claim 6, where the sensor comprises an optical sensor, and where the processor determines that fog or frost is present by analysis of an image captured by the optical sensor.

8. The method according to claim 6, where the sensor comprises an ultrasound sensor, and where the processor determines that fog or frost is present by analysis of ultrasound signals that change in the presence of fog or frost.

9. The method according to claim 1, where activating the energy transfer element comprises activating the heater element by less than 100%.

10. A mobile device, comprising:

one or more sensors that are configured to detect the presence of fog or frost on a surface of the mobile device;

a battery that provides power to the mobile device;

an energy transfer element that, when activated, removes fog or frost from the surface of the mobile device;

a programmed processor, within the mobile device, the programmed processor being programmed to;

read one or more sensors disposed in the mobile device to determine if there is a fog or frost condition;

upon detecting a fog or frost condition, activating the heater element to remove fog or frost; and

upon detecting an absence of the fog or frost condition, deactivating the energy transfer element.

11. The mobile device according to claim 10, where the one or more sensors comprises a temperature sensor, and where the processor determines that there is a fog or frost condition if the temperature rises by more than a threshold Δ

T over a prescribed period of time.

12. The mobile device according to claim 11, where the processor determines that a fog or frost condition has passed when the temperature sensor detects a temperature of a prescribed temperature T_Clear.

13. The mobile device according to claim 11, where the value of Δ

T is user adjustable.

14. The mobile device according to claim 11, where the temperature sensor measures a temperature of a window covering a display or an imaging optics system.

15. The mobile device according to claim 10, where the one or more sensors comprises a sensor that directly examines a surface of the mobile device to detect the presence of fog or frost.

16. The mobile device according to claim 15, where the sensor comprises an optical sensor, and where the processor determines that fog or frost is present by analysis of an image captured by the optical sensor.

17. The mobile device according to claim 15, where the sensor comprises an ultrasound sensor, and where the processor determines that fog or frost is present by analysis of ultrasound signals that change in the presence of fog or frost.

18. The mobile device according to claim 10, where the energy transfer element comprises a heater element and where activating the energy transfer element comprises activating the heater element by less than 100%.

19. The mobile device according to claim 10, where activation of the energy transfer element is determined by a state of the battery.

20. The mobile device according to claim 10, where the surface comprises at least one of a window covering a display of the mobile device, or a window covering an imager of the mobile device.
