Abstract

The shield is made of a radiation absorbing material such as lead or other comparably functioning substances in a L-shaped configuration. In use the shield is wrapped or folded around the display and antenna portions of the radiotelephone, leaving the keyboard free for easy operation. A viewing mirror B or mirrors allow the user to view the display without compromising the shield's effectiveness.

A LEAD RADIATION ABSORBING DIRECTIONAL SHIELD FOR MOBILE

PHONE USERS

PURPOSE: Devices used by this inventor and which are small button like adhesive backed objects purported to protect the mobile phone user have proved ineffective, headaches and dizziness kept him from using mobile phones for many years.

Even with a speaker phone at arms length the problems still persisted.

Disquieting gauoping increases in brain tumor incidence among children and heavy long term mobile phone users testify to the serious nature of the problem.

About 3% of persons are electro-sensitive to any form of electromagnetic radiation.

DESCRIPTION:

Ideally to be safe the mobile phone should be kept in a lead box but then it could not receive signals or be operated. The center screen and antenna portion Figs 1-4 G which emits radiation needs to be shielded Figs 1-4 E between the user both laterally and below to protect the genitals. The keyboard on the model tested did not emit any significant radiation through the lead shield Fig IS. So that it appears that the keyboard needs no shielding.

The drawings 1-4 illustrate the embodiment of a shield which has solved the inventors radiation symptoms. The disadvantage has been an increased weight problem of about 7 ounces but this can be solved by reducing the shield size to cover only the antenna portion or building it closer in to the battery in the mobile phone. It is preferably made of lead sheeting bent into an approximate L shape with the upright portion leaning over the mobile phone 10-30 degrees from vertical as shown in Figure 1 forming a 70-80 degree enclosure of the mobile phone. Since the lead is opaque the user cannot see the screen so as hinged mirror A reflects the screen details to the viewers eye C which must be read in reverse. The reversal is offset by a second mirror B on the mobile phone side of the shield Figs 1A and 4A. Silvered mirrors have no effect on the mobile phone function or reception of the EMRs. The user is shielded in the area above and below Area D which is protected by the radiation absorptive lead shield which must be covered or encapsulated by plastic or rubbery material to prevent any skin contact with the toxic lead. Possible future alternatives to lead could solve this problem.

Tests with a EMR meter show a 70% to 95% radiation protection in the shielded area "A" depending on the lead thickness or comparably protective material which may be discovered. The lead shield thickness may be from about two to four mm thick depending on the extent of protection required. Speaker phone mobile phones are necessary since the user's ears are one to two feet away and the mobile phone cannot be held next to the head. The mobile phone may be secured from below to the shield with Velcro or other practical means.

The shield as shown will add to the weight substantially in the area of 6-10 ounces if it is made of lead. However if it were built in the mobile phone being closer to the battery radiation source and subtending the same angle the same protection would be afforded with about � as much weight. Technology being ongoing a lighter alternative to lead could be used and still provide the directional protective principles herein revealed.

Claims

CLAIMS: 1. An approximately L shaped lead or other equally protective material device as described and as shown in figures to protect and shield the entire body of mobile phone users from the high levels electromagnetic radiation inherent in mobile phones.
2. Claim 1 above working in cooperation with a protective shield as described and shown in figures which by its configuration will not in any way interfere with normal mobile phone functions or usage by being open on all sides, forward and above so that incoming and outgoing signals are in no way attenuated except in the direction of the user and the earth below.
3. CJaims I and 2 above working in combination with a mirror viewing system which may be used to view the screen thus shielding the user's head and eyes while the mobile phone is receiving or emitting radiation and which will not simultaneously interfere with or weaken those functions in as much as mirrors are transparent to such electromagnetic radiations.Amendments to the Claims have been filed as follows: 5 Claims 1. A shield for protecting a user from electromagnetic radiation produced by a mobile phone the shield being a generally L shaped body composed of lead or a material comparably protective against electromagnetic radiation where, in use, one leg of the L shaped body extends to wrap around the back and one side of the mobile phone and the other leg extends generally upwardly with respect to the front of the mobile phone.2. A shield as in claim 1 wherein the shield body extends to shield the display and antenna portions of the mobile phone. 0*S 0** S. * * * 3. A shield as in claim I or claim 2 wherein the generally L Shaped body of * claim I is modified to a generally U shaped body in order to add the second -mirror so that display may be viewed by the user by way of two mirrors, with * each mirror mounted on a respective leg of the shield body.i.. ,** *
