Abstract

A system for providing electromagnetic interference (EMI) suppression includes a data processing device. The data processing device includes a payload module that suppresses EMI from an internal volume to an ambient environment by greater than 90 decibels; the internal volume adapted to house EMI emitting devices that generate EMI; and an input control system disposed within the internal volume. The input control system includes a command input device translatable along axes and adapted to mechanically input commands into the EMI emitting devices.

Claims (51)

1. A system for providing electromagnetic interference (EMI) suppression, comprising:

a data processing device comprising:

a payload module adapted to suppress EMI from an internal volume to an ambient environment by greater than 90 decibels;

the internal volume adapted to house EMI emitting devices that generate EMI; and

an input control system, disposed within the internal volume, wherein the input control system comprises a command input device translatable along axes and adapted to mechanically input commands into the EMI emitting devices.

2. The system of claim 1 , wherein the input control system further comprises:

a plurality of rails aligned with the axes; and

at least two rails of the plurality of rails are slidably coupled to one another,

wherein the command input device is fixedly coupled to one of the rails of the plurality of rails.

3. The system of claim 1 , wherein the command input device comprises:

first and second surfaces facing opposite directions, and each of the first surface and the second surface is adapted to provide a tactile input into the EMI emitting devices.

4. The system of claim 3 , wherein the EMI emitting devices are disposed on opposing sides of the internal volume, and the input control system is disposed between the opposing sides, and each of the first surface and the second surface face one of the opposing sides.

5. The system of claim 1 , wherein the payload module is adapted to dispose the EMI emitting devices on opposing sides of the internal volume, and the input control system is disposed between the opposing sides.

6. The system of claim 1 , further comprising:

a support module separate from the internal volume; and

the input control system further comprises a controller, disposed within the support module, configured to control translation of the command input device to mechanically input the commands into the EMI emitting devices.

7. The system of claim 1 , wherein the data processing device further comprises:

a front vent adapted to suppress the EMI from the internal volume to the ambient environment by greater than 90 decibels.

8. The system of claim 6 , wherein the data processing device further comprises:

a rear vent adapted to suppress the EMI from the internal volume to the ambient environment by greater than 90 decibels.

9. The system of claim 6 , wherein the front vent is adapted to rotate from a first position that electromagnetically seals the internal volume to a second position that:

electromagnetically opens the internal volume; and

enables physical access to the internal volume.

10. The system of claim 1 , wherein the EMI emitting devices are personal electronic devices.

11. The system of claim 9 , wherein the personal electronic devices comprise a cell phone.

12. The system of claim 1 , further comprising at least one selected from a group consisting of a camera, a thermal sensor, and a strain gauge, wherein the at least one is coupled to the command input device.

13. The system of claim 1 , further comprising a controller programmed to:

automatically suspend operation of the EMI emitting devices in response to a determination that the internal volume will shift from an EMI suppressed state that suppresses the EMI from the internal volume to the ambient environment by greater than 90 decibels to an EMI compromised state that does not suppress the EMI from the internal volume to the ambient environment by greater than 90 decibels.

14. The system of claim 1 , further comprising a controller programmed to:

automatically suspend operation of the EMI emitting devices in response to a determination that the internal volume has shifted from an EMI suppressed state that suppresses the EMI from the internal volume to the ambient environment by greater than 90 decibels to an EMI compromised state that does not suppress the EMI from the internal volume to the ambient environment by greater than 90 decibels.

15. A method for managing electromagnetic interference (EMI), comprising:

operating EMI emitting devices that emit EMI during operation while disposed in an EMI suppressed internal volume of a data processing device;

making a determination that the internal volume is in an EMI suppressed state;

based on the determination, performing an action set comprising:

inputting commands into the EMI emitting devices via a command input device positioned in the EMI suppressed internal volume while the EMI emitting devices are emitting EMI,

wherein the command input device is adapted to input the commands via mechanical actuation.

16. The method of claim 15 , wherein the mechanical actuation comprises a tactile interaction between the command input device and an EMI emitting device of the EMI emitting devices.

17. The method of claim 15 , further comprising:

making a second determination, while performing the action set, that the EMI suppressed internal volume will shift from the EMI suppressed state to an EMI compromised state; and

in response to the second determination:

suspending the performance of the action set; and

suspending the operation of the EMI emitting devices to cause the EMI emitting devices to suspend emission of EMI.

18. The method of claim 15 , further comprising:

making a second determination, while performing the action set, that the EMI suppressed internal volume has shifted from the EMI suppressed state to an EMI compromised state; and

in response to the second determination:

suspending the performance of the action set; and

suspending the operation of the EMI emitting devices to cause the EMI emitting devices to suspend emission of EMI.

19. The method of claim 15 , wherein the mechanical actuation comprises translating the command input device along axes to input commands into the EMI emitting devices.

20. The method of claim 15 , further comprising:

making a second determination, while performing the action set, that the EMI suppressed internal volume remains in the EMI suppressed state; and

in response to the second determination, continuing the performance of the action set.
