Abstract

Systems and methods for operating mobile devices having one or more environmental sensing systems for disrupting battery power.

Claims

1. A mobile data collection device comprising:

a housing adapted for hand held operation;

a data collection system for capturing and processing data associated with RFIDs or images containing data, the data collection system disposed at least partially within the housing;

a battery disposed in the housing for providing power to the mobile device;

an environmentally sealed chamber disposed within the housing;

a controller disposed in the environmentally sealed chamber for controlling the mobile device, the controller comprising volatile memory for storing data;

a sensor disposed within the environmentally sealed chamber for detecting a change in the environment of the environmentally sealed chamber;

wherein power is disrupted only from the battery to the volatile memory when a predetermined change detected by the sensor occurs in the environment; and

whereby the disruption of the power from the battery to the volatile memory erases security credential information from the volatile memory rendering certain functions of the mobile device unusable until the security credential information is re-entered.

2. A mobile device in accordance with claim 1, wherein the controller controls the disruption in the power.

3. A mobile device in accordance with claim 1, further comprising a battery control circuit that controls the disruption in the power.

4. A mobile device in accordance with claim 1, wherein the environmental sensor comprises at least one of the following:

an oxygen sensor;

a humidity sensor;

a temperature sensor;

a gas sensor and a particulate matter sensor.

5. A mobile device in accordance with claim 1, wherein the environmentally sealed chamber is purged with an inert gas.

6. A mobile device in accordance with claim 1, wherein the change in environment is the result of the chamber seal being breached.

7. A mobile data collection device comprising:

a housing adapted for hand held operation;

a data collection system for capturing and processing data associated with RFIDs or images containing data, the data collection system disposed at least partially within the housing;

a battery disposed in the housing for providing power to volatile memory disposed in the housing;

an environmentally sealed chamber disposed within the housing;

a sensor disposed within the environmentally sealed chamber for detecting changes in the environment of the environmentally sealed chamber;

a circuit to disrupt power only from the battery to the volatile memory based on a predetermined environment change detected by the sensor;

whereby the disruption of the power from the battery to the volatile memory erases security credential information from the volatile memory rendering certain functions of the mobile device unusable until the security credential information is re-entered.

8. A mobile device in accordance with claim 7, wherein the environmental sensor comprises at least one of the following:

an oxygen sensor;

a humidity sensor;

a temperature sensor;

a gas sensor and a particulate matter sensor.

9. A mobile device in accordance with claim 7, wherein the environmentally sealed chamber is purged with an inert gas.

10. A mobile device in accordance with claim 7, wherein the environmental sensor comprises an oxygen sensor.

11. A mobile device in accordance with claim 7, wherein the change in environment is the result of the chamber seal being breached.

12. A method of operating a mobile data collection device comprising:

disposing a battery in a housing adapted for hand held operation for providing power to volatile memory disposed in the housing;

disposing a data collection system for capturing and processing data associated with RFIDs or images containing data at least partially within the housing;

disposing an environmentally sealed chamber within the housing;

disposing a sensor within the environmentally sealed chamber;

utilizing the sensor to detect a change in the environment of the environmentally sealed chamber;

utilizing a circuit to disrupt power only from the battery to the volatile memory based on an environment change detected by the sensor;

whereby the disruption of the power from the battery to the volatile memory erases security credential information from the volatile memory rendering certain functions of the mobile device unusable until the security credential information is re-entered.

13. A method of operating a mobile device in accordance with claim 12, wherein the environmental sensor comprises at least one of the following:

an oxygen sensor;

a humidity sensor;

a temperature sensor;

a gas sensor and a particulate matter sensor.

14. A method of operating a mobile device in accordance with claim 12, wherein the environmentally sealed chamber is purged with an inert gas.

15. A method of operating a mobile device in accordance with claim 12, wherein the environmental sensor comprises an oxygen sensor.
