EMI shielding containers

Abstract

Embodiments of electromagnetic interference (EMI) shielding containers are disclosed according to the present invention. The EMI shielding containers are especially useful for protecting sources of electronic evidence from EMI contamination prior to data extraction. However, the embodiments of EMI shielding containers of the present invention may be used in any context where a wireless device is to be shielded from transmitting or receiving electromagnetic signals. Embodiments of methods of using EMI shielding containers to extract data from electronic devices are also disclosed.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] This invention relates generally to electromagnetic interference (EMI) shields, and more specifically relates to pouches and tents for use in shielding electronics from EMI and wireless communication signals. [0003] 2. Description of Related Art [0004] It is well known that electromagnetic signals propagate through vacuum with little signal attenuation. It is also well known that electromagnetic radiation and signals attenuate when propagating through materials other than a vacuum. Electromagnetic signals rapidly attenuate in metal materials. For this reason, metal housings are commonly used to hold electronic equipment in order to minimize EMI caused by the electronics associated with the electronic equipment when operating. While metal housing are useful for shielding electronic objects, they are generally bulky, heavy, non-portable and not suitable for containing arbitrarily sized electronic objects. [0005] U.S. ...

AI Technical Summary

Problems solved by technology

While metal housing are useful for shielding electronic objects, they are generally bulky, heavy, non-portable and not suitable for containing arbitrarily sized electronic objects.

The Carbonneau and Piemonte et al. containers are not designed to provide for external connection to evidence gathering devices while shielding the portable wireless device containing the evidence of interest.

Furthermore, the Carbonneau bag includes a layer of bubble pack cushioning material for mechanical protection of electrical object inside which is generally unnecessary in the forensic evidence gathering context and adds cost to the EMI container.

Similarly, the Piemonte et al. container includes an unnecessary vapor barrier layer that ads cost.
