Abstract
A glove box enclosing a volume shielded from electromagnetic radiation by the glove box wherein the gloves are formed from conductive material such as chain mail and are conductively and shieldingly attached around apertures in the walls of the glove box, permitting an operator to manipulate directly a device under test within the glove box while maintaining the shielding continuity of the box. A shielded window and an interior light can be included to facilitate viewing of a device within the box during manipulation of the device. The glove box provides an inexpensive, fully-shielded environment for the testing, tuning, adjusting, or repair of RF transmitting or receiving devices such as pagers, electronic notebooks, and cellular telephones.
Claims13
An electromagnetic isolation chamber containing a volume of space electromagnetically isolated from the surrounding environment, comprising:
- a) a wall enclosing said volume, said wall having first electromagnetic shielding surrounding said volume and having an aperture therethrough wherein said first shielding is disrupted;
- and
- b) a flexible, conductive second electromagnetic shielding disposed within said chamber and covering said aperture in said wall and being conductively and shieldingly attached to said first electromagnetic shielding of said wall around the periphery of said aperture, said second shielding being deformable and of sufficient size to enclose objects which may be inserted into said chamber through said aperture and to permit tactile feel and manipulation of said objects within said chamber, so that continuity of electromagnetic isolation of said volume is maintained through said insertion.
