Abstract

A method for managing electromagnetic interference (EMI) includes: obtaining a request; in response to the request: terminating EMI generation by EMI emitting devices in an EMI suppressed internal volume of a data processing device to place the EMI emitting devices in a quiet state; placing the EMI suppressed internal volume into an EMI suppression compromised state to obtain access to the EMI emitting devices in the quiet state; replacing one of the EMI emitting devices in the quiet state, to obtain updated EMI emitting devices, while: the EMI suppressed internal volume is in the EMI suppression compromised state, and the EMI emitting devices are in the quiet state; placing the EMI suppressed internal volume into an EMI suppressed state after replacing the one of the EMI emitting devices; and enabling EMI generation by the updated EMI emitting devices to place the updated EMI emitting devices into an active state.

First claim

1 - 14 . (canceled)

15 . A method for managing electromagnetic interference (EMI), comprising:
obtaining a device change request; in response to the device change request:
terminating EMI generation by EMI emitting devices in an EMI suppressed internal volume of a data processing device to place the EMI emitting devices in a quiet state;
placing, after the terminating, the EMI suppressed internal volume into an EMI suppression compromised state to obtain access to the EMI emitting devices in the quiet state;
replacing one of the EMI emitting devices in the quiet state, to obtain updated EMI emitting devices, while:
the EMI suppressed internal volume is in the EMI suppression compromised state, and the EMI emitting devices are in the quiet state;
placing the EMI suppressed internal volume into an EMI suppressed state after replacing the one of the EMI emitting devices; and
enabling EMI generation by the updated EMI emitting devices to place the updated EMI emitting devices into an active state.

16 . The method of claim 15 , wherein the EMI emitting devices are cell phones.

17 . The method of claim 15 , wherein the data processing device comprises a frame mountable chassis.

18 . The method of claim 17 , wherein the frame mountable chassis is mounted in a frame that does not provide EMI suppression for the data processing device.

19 - 20 . (canceled)

21 . The method of claim 17 , 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 80 decibels.

22 . The method of claim 21 , 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 80 decibels.

23 . The method of claim 22 , wherein the front vent and the rear vent define an airflow path through the internal volume.

24 . The method of claim 21 , 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.

25 . The method of claim 17 , 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 80 decibels, wherein the front vent, while in a first position, bounds a side of the internal volume.

26 . The method of claim 15 , wherein the EMI emitting devices are tablet computers.

27 . The method of claim 15 , wherein only the data processing device is adapted to provide EMI suppression.

28 . The method of claim 15 , wherein an electronics payload, disposed in the internal volume, adapted to provide communication services for the EMI emitting devices.
