Radiated Electromagnetic Susceptibility (RES) testing is one of the mandatory international EMC Electromagnetic Compatibility (EMC) requirements for electronic products, such as computer systems, shipped to Europe and to some Asian countries. During RES testing of a smart card reader connected to a Trusted Key Entry (TKE) workstation for some computer systems, the security key must be continuously entered while the card reader and the link to the workstation are subjected to an electromagnetic field over a wide range of frequencies. Since test personnel should not be subjected to radiation continuously for a lengthy period of time, a programmable remote robotic key entry apparatus is desirable. The remote key entry apparatus must not be affected by the radiation, otherwise the failure mode during RES testing would be inconclusive.

Radio Frequency Immune Programmable Remote Robotic Key Entry Apparatus

Disclosed is an apparatus that provides remote key entry capability and is immune to radiated electromagnetic field testing. The programmable remote robotic key entry apparatus includes a control station, e.g. a personal computer, outside the RES (or EMC) chamber that transmits key stroke instructions over a fiber optic link to a robotic hand within the chamber that responds to the instructions by making corresponding key strokes on either a keypad or keyboard as shown in the Figure.

  As shown in the FIGURE, the apparatus includes a sender unit, e.g. a computer that transmits key stroke instructions over a fiber optic interface, a receiver unit (with an internal battery in this embodiment) that decodes the key stroke instructions transmitted via the fiber optic link and that activates at least one relay or at least one solenoid inside the robotic arm in response to the instructions, and a robotic hand that performs the actual key entries on the keypad or keyboard. In another embodiment, the same function can be achieved (without the use of a fiber optic interface) by using air hoses that feed into the RES chamber to activate air pistons in the robotic hand to perform key entries. In this embodiment, a control circuit will interface with the the sending unit to activate air solenoids or relays for the purpose of providing compressed air through the hoses in order to activate the hand in respons...
