Portable Electromagnetic Interference Shield

Abstract

An electromagnetic interference shield having a main enclosure and optionally at least one auxiliary enclosure. The auxiliary enclosure and the main enclosure have an interior that is continuous with each other. The auxiliary enclosure is made of elastic Faraday material. The outer layer and inner layer may be transparent to view the electronic device. An auxiliary cable with filtering mechanisms may be provided inside a sleeve to allow access and transfer of data from the electronic device while still in the main enclosure.

         5 . The EMI shield of  claim 1 , wherein the main enclosure further comprises a hole through which the electronic device can transmit data to an external device. 
     
     
         6 . The EMI shield of  claim 1 , wherein the inner layer comprises a transparent portion to view the electronic device inside. 
     
     
         7 . The EMI shield of  claim 1 , wherein the main enclosure has a triangular cross-section defined by a front side, a back side opposite the front side, a bottom side adjacent and attached to the front side and the back side, and two sides opposite each other and attached to the front side, the back side, and the bottom side, wherein one side is the auxiliary enclosure. 
     
     
         8 . The EMI shield of  claim 7 , where in the two sides are made of elastic Faraday material. 
     
     
         9 . A method of using an electromagnetic interference (EMI) shield, comprising
 (a) being provided with the EMI shield, the EMI shield comprising a flexible main enclosure to shield the electronic device from electromagnetic interference; and an auxiliary pouch attached to the main enclosure, wherein the main enclosure comprises:
 i. an outer layer; 
 ii. an inner layer enveloped by the outer layer; 
 iii. a first opening to receive the electronic device into the inner layer; and 
 iv. a second opening through which the auxiliary pouch is attached to the main enclosure; 
   (b) placing the electronic device through the first opening into the main enclosure of the EMI shield; and   (c) sealing the first opening.   
     
     
         10 . The method of  claim 9 , further comprising:
 (a) bunching the auxiliary pouch into a user's hand;   (b) inserting the user's hand with the auxiliary pouch into the main enclosure while keeping the auxiliary pouch taut;   (c) performing an action on the electronic device via the auxiliary pouch.   
     
     
         11 . The method of  claim 10 , further comprising slowly releasing portions of the auxiliary pouch to reach deeper into the main enclosure. 
     
     
         12 . The method of  claim 10 , further comprising
 (a) extending a finger of the user to stretch a portion of the auxiliary pouch to maintain tautness; and   (b) performing the action on the electronic device with the finger without compromising the shielding and without allowing any other portion of the auxiliary pouch from touching the electronic device.   
     
     
         13 . The method of  claim 10 , further comprising:
 (a) grasping a secondary device inside the main enclosure with the auxiliary pouch while maintaining tautness of the auxiliary pouch; and   (b) performing the action on the electronic device with the secondary device without compromising the shielding and without allowing any other portion of the auxiliary pouch from touching the electronic device.   
     
     
         14 . The method of  claim 9 , further comprising:
 (a) inserting a user's hand into the main enclosure through the second opening;   (b) grasping the electronic device with the auxiliary pouch; and   (c) removing the electronic device from the main enclosure while keeping the electronic device enveloped in the auxiliary pouch sufficiently to keep the electronic device shielded from the main enclosure.   
     
     
         15 . The method of  claim 14 , further comprising:
 (a) opening the main enclosure at the first opening to insert or remove a second device;   (b) inserting or removing a second device into or from the main enclosure, respectively;   (c) closing and sealing the first opening;   (d) inserting the auxiliary pouch back into the main enclosure; and   (e) releasing the electronic device from the auxiliary pouch.   
     
     
         16 . An electromagnetic interference (EMI) shield, comprising:
 (a) a main enclosure to shield an electronic device from electromagnetic interference, the enclosure, comprising:
 i. a protective layer having a transparent window, 
 ii. a shielding layer having a transparent portion overlapping the transparent window, 
 iii. a first opening to receive the electronic device, and 
 iv. an orifice through which a device cable connectable to the electronic device can exit; and 
   (b) a sleeve having a first end and a second end opposite the first end, the first end of the sleeve operatively associated with the enclosure for accessing and connecting to the electronic device while the electronic device is inside the enclosure, without compromising shielding from the electromagnetic interference, the sleeve, comprising an inner layer for shielding.
