Self-contained secured work station
First Claim
1. Security apparatus comprisingwork table means providing a substantially horizontal surface for supporting first electronic equipment;
- a cabinet for receiving and shielding second electronic equipment, said cabinet having first shielding means for substantially preventing the passage of electromagnetic energy whereby coupling between said energy and said electronic equipment is precluded;
signal transmission means for electrically connecting said first electronic equipment to said second electronic equipment;
second shielding means on said signal transmission means for substantially preventing the passage of electromagnetic radiation; and
wherein said work table means, said cabinet, and said signal transmission means are physically connected to form a single unit.

Abstract
A work station is designed for use with electronic equipment whereby the placement of the equipment in the work station prevents undesired electromagnetic coupling between various pieces of the electronic equipment. A substantially horizontal work surface is provided between a cabinet at one end and a safe at the other end. The cabinet provides a Faraday cage for receiving a MODEM and for preventing the passage of electromagnetic radiation, whereby undesired coupling between the MODEM and other pieces of electronic equipment is substantially precluded. The safe is designed to house an encryption device. A horizontal work surface supports electronic input equipment, such as a word processor, in position for convenient use by an operator. The electronic equipment on the work surface is connected to the encryption device in the safe which is, in turn, connected to a modulator-demodulator (MODEM) in the cabinet. All of the electrical connections between these pieces of equipment are shielded to prevent undesired coupling. The work station is self-contained and is designed to comply with standards relating to secured work areas. The work station itself complies with the standards so that an appropriate environment may be easily secured by simply employing the self-contained work station in accordance with the invention.
