Abstract

A portable secure-telephone communication module (Figs. 1-4) including a collapsible enclosure (4) for holding a person desiring to perform secure remote telephone communications, a secure telephone remote communication device (166) in the enclosure (4), and RF shielding for the enclosure to inhibit RF leakage for preventing eavesdropping from outside the enclosure (4).

Claims

[received by the International Bureau on 25 April 1995 (25.04.95); original claim 19 amended; new claim 29 added; remaining claims unchanged (3 pages)] modulated non-visible light waves from the enclosure.
18. The portable secure communications module of claim 11 further including mean for inhibiting sound leakage to the outside of said enclosure.
19. The portable secure communications module of claim 18 in which said means fo inhibiting includes means for modulating said cover for disrupting laser interception an inhibiting noise.
20. The portable secure communications module of claim 19 in which said mean for modulating includes means for directing noise at said cover.
21. The portable secure communications module of claim 1 further including mean for projecting noise out from said enclosure to mask voice leakage from said enclosure.
22. The portable secure communications module of claim 21 further including mean for determining when the person in said enclosure is using said communication device.
23. The portable secure communications module of claim 22 in which said means fo projecting noise is responsive to said means for determining when a person is using sai communication device to mask noise leakage when the person is using the communicatio device.
24. The portable secure communications module of claim 1 further including mean for providing power to the on-board electronic systems and means for filtering said power t prevent power line signal interception.
25. The portable secure communications module of claim 1 further including mean for ventilating said enclosure. communication means for off site signalling of module status.
36. The portable secure communications module of claim 1 further including motion detection means communicating with the enclosure outside for detecting motion in an area outside the module.
37. The portable secure communications module of claim 15 further including metallic zipper means electrically communicating with said metallic substance for providing an RF shielded opening in said flexible cover.
38. A portable secure telephone communications module, comprising: a collapsible enclosure including a collapsing pantograph-type frame covered with an RF shielded flexible cover for collapsing with said frame into at least one or both rigid base and top members; means for ventilating said enclosure, including RF shielded ventilation ports; means for projecting wide-band noise from said enclosure to mask voice audio leakage from said enclosure; means for vibrating said flexible cover, and rigid top/bottom cabinet sections to inhibit external monitoring of said cover and cabinet sections; and a secure remote telephone communication device in said enclosure for providing for secure communications from said enclosure.
39. A portable secure-telephone communications module, comprising: a collapsible enclosure for holding a person desiring to perform secure remote telephone communications, said collapsible enclosure including a collapsing frame and a flexible cover for collapsing with said frame; a secure remote telephone communication device in said enclosure; means for RF shielding said enclosure to inhibit RF leakage for preventing eavesdropping fram outside the enclosure including a metallic substance in said flexible cover; and metallic zipper means electrically communicating with said metallic substance for providing an RF shielded opening in said flexible cover.
STATEMENT UNDER ARTICLE 19
Applicant submits Replacement Sheet 34 of 4/20/95 with claims 18-25, and Replacement Sheets 36-1 and 36-2 of 4/20/95 with claims 36-39.
Original sheet 34 contained claims 18-25, all being dependent from different independent claims. Applicant has only redrafted lines 2 and 3 of claim 19 to more exactly claim the means for modulating feature of applicant's invention.
Original sheet 36 contained claims 36-38 with claims 36 and 37 being dependent from independent claims 1 and 15, respectively. Claim 38 was an independent claim. Applicant has only added new independent claim 39 to incorporate dependent claim 37 into an independent form. However, due to the length of new claim 39 it has caused applicant to submit Replacement Sheets 36-1 and 36-2 of 4/20/95.
Therefore, applicant submits that these amendments, which were allowed in the companion U.S. case, do not go beyond the disclosure in this international application as filed on October 6, 1994, and amended for certain informalities on November 29, 1994.
