Abstract

A method and apparatus for housing an electronic device are provided. The apparatus includes an environmentally sealed chamber to protect the electronic device from harsh environments. The environmental conditions of the chamber are controllable using environmental controls which are controlled by digital processor with a stored program coupled with sensors. The digital processor may also control the application of power from an external interface. The apparatus also includes a self-contained power source running from a primary fuel. A control system is provided for managing power production and energy storage to maintain continuity of environmental conditions.

Claims

1. A portable apparatus for housing an electronic device, comprising:

an environmentally sealed chamber having environmental conditions, wherein the chamber is adapted to receive the device so that the device is operable inside the chamber;

environmental controls that control the environmental conditions;

a digital controller for monitoring the environmental conditions of the chamber and for selectively activating and deactivationg the environmental controls to control the environmental conditions; and

a self contained-power source configured to provide power to the electronic device,

wherein the digital controller is further configured to regulate power generated by the self-contained power source.

2. The apparatus of claim 1, wherein the sealed chamber is adapted to house at least one of the group comprising electronic circuit boards, electronic modules, and electronic units.

3. The apparatus of claim 1, where the digital controller is further configured to regulate power received from an external power source.

4. The apparatus of claim 1, further comprising a plurality of sensors configured to detect environmental conditions and provide information regarding the environmental conditions to the digital controller.

5. The apparatus of claim 4, wherein the environmental controls include mechanical controls configured to alter environmental conditions inside the chamber, wherein the mechanical controls are operated under the control of the digital controller based, at least in part, on the information received from the plurality of sensors.

6. The apparatus of claim 1, wherein the digital controller is configured to control the environmental controls based, at least in part, on a standard operational profile which specifies desired environmental conditions.

7. The apparatus of claim 1, further comprising an operator interface configured to provide information from the digital controller to an operator through an input/output device and to allow an operator to monitor and control the apparatus.

8. The apparatus of claim 7, wherein the operator interface further comprises a data network interface configured to allow the operator to remotely monitor and control the apparatus.

9. A method for housing an electronic device in a portable apparatus, comprising acts of:

providing, in the portable apparatus, an environmentally sealed chamber having environmental conditions therein, wherein the chamber is adapted to receive the device so that the device is operable inside the chamber;

providing, in the portable apparatus, environmental controls that control the environmental conditions;

providing, in the portable apparatus, a digital controller for monitoring the environmental conditions of the chamber and for selectively activating and deactivating the environmental controls to control the environmental Conditions; and

providing a self-contained power source configured to generate power for controlling the environmental conditions of the chamber,

wherein the digital controller regulates power generated by the self-contained power source.

10. The method of claim 9, where the digital controller regulates power received from an external power source.

11. The method of claim 9, further comprising an act of providing a plurality of sensors configured to detect environmental conditions and provide information regarding the environmental conditions to the digital controller.

12. A method for housing an electronic device in a portable apparatus, comprising:

housing an electronic device in an environmentally sealed chamber of the portable apparatus, the chamber having environmental conditions therein, wherein the device is operable inside the chamber;

controlling the environmental conditions using environmental controls;

monitoring the environmental conditions and selectively activating and deactivating the environmental controls using a digital controller to control the environmental condition; and

providing a self-contained power source configured to generate power for controlling the environmental conditions of the chamber,

wherein the digital controller regulates power generated by the self-contained power source.

13. The method of claim 12, further comprising an act of using a self-contained fuel source to provide power for controlling the envirotmental controls and for powering the electronic device.

14. The method of claim 13, further comprising an act of regulating the power generated by the self-contained fuel source.

15. The method of claim 13, further comprising an act of storing unused power generated by self-contained fuel source.

16. The method of claim 12, further comprising an act of adjusting the environmental conditions inside the chamber based, at least in part, on input received from a plurality of sensors inside the chamber.
