Abstract

An accessory for a mobile communication device such as a mobile telephone (1) comprises a shield (12) adapted to provide an attenuating effect to radiation from the mobile communication device (1), and means (11) to mount the shield on the device so that, in use, the shield is located between the antenna on the device and a person using the device. The shield (12) may form part of a case (11) for a communication device such as a mobile telephone.

Claims

AMENDED CLAIMS[received by the International Bureau on 5 October 1994 (05.10.94); original claims 1-20 replaced by amended claims 1-12 (2 pages)]
1.. An accessory for a mobile communication device, said accessory comprising a casing to receive the housing of the communication device, the casing incorporating a shield to provide an attenuating effect to radiation emanating from the housing of the device, the arrangement being such that, in use, the shield is located between the device and a person using the device.
2. An accessory according to Claim 1 wherein the case incorporates an electrically conducting layer to attenuate the radiation from the device.
3. An accessory according to Claim 2 wherein the case is formed of a laminate including said electrically conducting layer.
4. An accessory according to Claim 2 or 3 wherein the electrically conducting layer is in the form of a metallic foil.
5. An accessory according to Claim 4 wherein the metallic foil is perforated to form a micro-screen.
6. An accessory according to Claim 2 or 3 wherein the conductive layer is metallic scrim.
7. An accessory according to any one of the preceding Claims wherein part of the shield is movable from an operative position to a collapsed position.
8. An accessory according to Claim 7 wherein the said part of the shield is adapted to be moved to the collapsed position by folding the shield about a substantially central line and then folding back two protruding portions of the said part of the shield.
9. An accessory according to Claim 7 or 8 wherein the said part of the shield is provided with elements of hook and/or loop material to retain the said part of the shield in the collapsed condition.
10. An accessory according to any one of the preceding Claims wherein the said communication device is a mobile telephone and a region of the shield intended to be adjacent the ear-piece of the telephone is such that sound waves may pass through the shield in that region.
11. An accessory according to Claim 10 wherein the shield incorporates an electrically conducting micro- screen, the micro-screen being exposed in the said region so that sound waves may pass through the apertures in the micro-screen.
12. A mobile communication device in combination with an accessory according to any one of the preceding Claims.
STATEMENT UNDER ARTICLE 19
The Claims have been amended in order to clarify that the invention is an accessory which comprises a casing, which casing incorporates a shield to provide an attenuating effect to radiation emanating from the housing of the device.
CA 2,022,958 shows a screening plate which is mounted on a hand-set by means of a retaining clip. This Specification does not show a casing which incorporates a shield to provide an attenuating effect.
EP-A-0,348,187 shows a casing for a hand-held portable radio telephone, the casing itself incorporating an antenna.
It is to be appreciated that the device of European Publication 0, 348,187 does not provide any shielding effect whatsoever, but instead places the antenna at a position immediately adjacent the person using the device.
A person seeking to combine the teaching of EP-A-0,348,187 and CA 2,022,958 would not be led to the subject matter of the present main Claim.
