Abstract

A system for providing electromagnetic interference (EMI) suppression for data processing devices includes a frame adapted to receive a data processing device of the data processing devices. The system further includes the data processing device that includes a payload module adapted to suppress EMI from an internal volume to an ambient environment by greater than 80 decibels. The data processing device further includes the internal volume adapted to house EMI emitting devices that generate EMI.

Claims (33)

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

a frame adapted to receive a data processing device of the data processing devices;

and the data processing device comprising:

a payload module adapted to suppress EMI from an internal volume to an ambient environment by greater than 80 decibels;

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

a front vent directly attached to a front of the payload module and adapted to suppress the EMI from the internal volume to the ambient environment by greater than 80 decibels;

a rear vent directly attached to a rear of the payload module and adapted to suppress the EMI from the internal volume to the ambient environment by greater than 80 decibels, wherein the rear vent is directly attached to the rear of the payload module at a first opening side of the rear vent;

a support module comprising a fan and adapted to regulate a flow of gasses within the internal volume of the data processing device, wherein the support module is disposed in the ambient environment and attached to a second opening side of the rear vent opposite to the first opening side, wherein the fan faces the rear vent and the front vent such that gases flowing into the front vent are pulled by the fan towards the rear vent in a straight line through the payload module and exhausted out of the rear vent; and

a computing device disposed on an internal surface of the data processing device that wirelessly communicates with each of the EMI emitting devices and that causes, when receiving an instruction to terminate EMI emission from a user of the data processing device, the EMI devices to terminate generation of the EMI.

2. The system of claim 1 , wherein the front vent and the rear vent define an airflow path through the internal volume.

3. The system of claim 1 , 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 EMI emitting devices.

4. The system of claim 1 , wherein the payload module comprises:

a top door adapted to suppress the electromagnetic interference from the internal volume to the ambient environment by greater than 80 decibels;

a first side adapted to suppress the electromagnetic interference from the internal volume to the ambient environment by greater than 80 decibels;

a second side adapted to suppress the electromagnetic interference from the internal volume to the ambient environment by greater than 80 decibels; and

a bottom adapted to suppress the electromagnetic interference from the internal volume to the ambient environment by greater than 80 decibels,

wherein the top door, the first side, the second side, and the bottom bound four sides of the internal volume.

5. The system of claim 4 , wherein:

the front vent, while in a first position, bounds a fifth side of the internal volume.

6. The system of claim 5 , wherein

the rear vent, while in a first position, bounds a sixth side of the internal volume.

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

8. The system of claim 7 , wherein the personal electronic devices comprise a cell phone.

9. The system of claim 7 , wherein the personal electronic devices comprise a tablet computer.

10. The system of claim 1 , further comprising:

a second data processing device comprising a second internal volume,

wherein the second internal volume is adapted to house second EMI emitting devices in an orientation that is different from an orientation in which the internal volume is adapted to house the EMI emitting devices.

11. The system of claim 1 , further comprising:

a second data processing device comprising a second internal volume,

wherein the second internal volume is adapted to house second EMI emitting devices of a first device type that is different from a second device type which the internal volume is adapted to house.

12. The system of claim 1 , wherein only the data processing devices of the system are adapted to provide EMI suppression.
