Abstract

An EMI shielded isolation chamber is provided, having an integral manipulator for manipulating electronic devices such as cell phones within the chamber, whereby a probe can be precisely positioned to selectively and directly actuate controls, switches, and keypads upon the devices anywhere in the chamber upon rotation of a probe tip. Extensible collapsible shielding boots are coupled between wall portions of the shielded chamber, adjacent a wall mounted manipulator support gimbal, and forward or rearward portions of the mechanical manipulator for preventing EMI signals from entering or leaving the shielded chamber. Alternatively, the gimbal constitutes the shielding device whereby a metallic hollow ball, slidably and rotatably supporting and containing the elongated manipulator, is mechanically biased snugly against a concave metallic member to block radiation from entering or leaving the shielded chamber. The probe tip is self-illuminated by an LED, thus providing illumination for the portion of the device being actuated.

Claims

1. An EMI shielded chamber for containing devices to be tested or manipulated within the shielded chamber having

(a) a movable mechanical manipulator for manipulating said devices within said shielded chamber and having manipulator support means, coupled to a wall portion of said shielded chamber, for supporting a first manipulator portion positioned internally with respect to said shielded chamber for directly contacting selected portions of said devices within said shielded chamber and a second manipulator portion positioned externally with respect to said shielded chamber for moving said first manipulator portion;

and

(b) an extensible and collapsible EMI shielding means coupled between said wall portion of said shielded chamber and said movable mechanical manipulator for preventing EMI signals from entering said shielded chamber.

2. The shielded chamber of claim 1 wherein said extensible and collapsible shielding means surrounds an internal portion of the first manipulator portion for blocking external EMI signals from entering the shielded chamber as said mechanical manipulator slides back and forth within said support means and through said wall portion and tilts in orthogonal directions in response to actuation of said second manipulator portion.

3. The shielded chamber of claim 1 wherein said extensible and collapsible shielding means surrounds an external portion of the first mechanical manipulator portion for blocking external EMI signals from entering the shielded chamber as the mechanical manipulator slides back and forth within said support means and through said wall portion and tilts in orthogonal directions in response to actuation of said second manipulator portion.

4. The shielded chamber of claim 1 wherein said support means is a gimbal permitting a probe head of said first manipulator portion to move in any direction within said shielded chamber for directly contacting selected portions of said devices within said shielded chamber.

5. The shielded chamber of claim 2 wherein said support means is a gimbal permitting a probe head of said first manipulator portion to move in any direction within said shielded chamber for directly contacting selected portions of said devices within said shielded chamber.

6. The shielded chamber of claim 3 wherein said support means is a gimbal permitting a probe head of said first manipulator portion to move in any direction within said shielded chamber for directly contacting selected portions of said devices within said shielded chamber.

7. The shielded chamber of claim 4 wherein said probe head has an illumination device for directly illuminating portions of said devices in the vicinity of said probe head.

8. The shielded chamber of claim 5 wherein said probe head has an illumination device for directly illuminating portions of said devices in the vicinity of said probe head.

9. The shielded chamber of claim 6 wherein said probe head has an illumination device for directly illuminating portions of said devices in the vicinity of said probe head.

10. The shielded chamber of claim 4 wherein said manipulator support means rotatably supports said mechanical manipulator enabling said probe head to be rotated within said shielded chamber for directly contacting selected portions of said devices.

23. The shielded chamber of claim 1 including a shielding member detachably mounted over an apertured external wall portion of said shielded chamber to continue shielding of interior portions of the chamber having said devices therein, upon storage or transportation of the shielded chamber.

11. An EMI shielded chamber for containing devices to be manipulated therein having

(a) a movable mechanical manipulator for manipulating said devices within said shielded chamber and having manipulator support gimbal, coupled to a wall portion of said shielded chamber, for supporting a first elongated manipulator portion, slidably movable with respect to said shielded chamber, and having a probe head for directly contacting selected portions of said devices within said shielded chamber, and for supporting a second elongated manipulator portion positioned externally with respect to said shielded chamber for enabling actuation of said first manipulator portion and the probe head thereon upon actuation of said second manipulator portion, and wherein said manipulator support gimbal is configured to permit the probe head of said first manipulating portion to be moved in any of three orthogonal direction within said chamber for enabling said probe head to directly contact selected portions of said devices within said shielded chamber and

(b) an extensible and collapsible EMI shielding means coupled between said wall portion of said shielded chamber and a portion of said mechanical manipulator for preventing EMI signals from entering said shielded chamber and

(c) wherein said extendable and collapsible shielding means takes the form of a boot of EMI shielding material surrounding a manipulator portion.

12. The shielded chamber of claim 11 wherein said gimbal rotatably supports said mechanical manipulator enabling said probe head to be rotated within said shielded chamber for directly actuating portions of said devices.

13. The shielded chamber of claim 11 wherein said probe head has an illumination device for directly illuminating portions of said devices in the vicinity of said probe head.

14. The shielded chamber of claim 12 wherein said probe head has an illumination device for directly illuminating portions of said devices in the vicinity of said probe head.

15. The shielded chamber of claim 13 wherein a battery is positioned within a compartment of the second manipulator portion and is electrically coupled to said illumination device.

22. The shielded chamber of claim 13 wherein said illumination device comprises a light transmitting tapered probe tip for directing a narrow light beam through said probe tip precisely upon selected portions of said devices.

24. The shielded chamber of claim 11 including a shielding member detachably mounted over an apertured external wall portion of said shielded chamber to continue shielding of interior portions of the chamber having said devices therein, upon storage or transportation of the shielded chamber.

16. An EMI shielded chamber for containing devices to be tested or manipulated within said shielded chamber having

(a) a movable mechanical manipulator for manipulating said devices within said shielded chamber;

(b) manipulator support means coupled to a wall portion of said shielded chamber, for supporting a first manipulator portion positioned internally with respect to said shielded chamber for directly contacting said devices within said shielded chamber and a second manipulator portion positioned externally with respect to said shielded chamber for moving said first manipulator portion; and

(c) wherein said manipulator support means includes a rotatable metallic hollow ball containing a portion of said movable mechanical manipulator, said rotatable metallic hollow ball being mechanically biased snugly against a concave metallic member, for isolating interior portions of said shielded chamber from EMI radiation external of said shielded chamber.

17. The shielded chamber of claim 16 wherein said manipulator support means rotatably supports a portion of said mechanical manipulator, enabling a probe head at a terminal portion of the mechanical manipulator to be rotated within said shielded chamber for directly contacting portions of said devices.

18. The shielded chamber of claim 16 wherein a probe head positioned upon said first manipulator portion has an illumination device for directly illuminating portions of said devices in the vicinity of said probe head.
