Abstract

The aerial screen would be pulled out of a slot when mobile phone is in use, and would lock into position when fully extended. After use it is eased back down into the slot and locked into storage position. Alternatively the aerial and the screen is springloaded by design, so that it can be either driven by a spring loaded device or an air damping device, to enable the screen and aerial to be released together and work together with use of a control button or applied top aerial screen pressure. The aerial screen remains connected to the slot throughout use and storage. Positioning the aerial screen in front of the aerial offers protection to the mobile phone user. The screen is earthed to the casing of the mobile phone. It can be made of anodized aluminium, or an alloy covered with a thin layer of lead.

Description

2353143 Mobile Phone Aerial Screening This invention relates to current
mobile phones and the concern of electromagnetic radiation on the human brain, and the possible hazards to mobile phone users due to the microwave radiation and absorption to the brain tissue and risks to the public.
The use of this screen would drastically reduce the possibility of risk and would provide some form of protection. Therefore, reducing the exposure to the head and delicate brain tissue by forming a screen between the transmitting aerial and mobile phone user's head.
The screen will be simple and easy to use. During manufacture of the mobile phone, the design would include a small slot added to the body of the phone as part of the design. The phone casing to be made of an electrically conductive metal.
Add a small screen of an electrically conductive material. This can be anodised al-uminium or an alloy with a thin coating of lead during manufacture to blend in with the design of the mobile phone. The screen is connected to the metal casing by a flexible static earthing connection or flexible electrical connection. Therefore, the screen will be electrically conductive to the metal casing. The screen and metal casing is totally isolated from the internal electronics of the mobile phone.
This small screen would be pulled out of the slot when the mobile phone is in use, and eased back into the slot in stored position when not in use. Internal side guide rails in position for ease of movement of the aerial screen up and down the slot.
z The dimensions of the aerial screen would depend on the length of the aerial and the design of the mobile phone. For example, if the aerial was 2cm long then the screen would be 3cm long and base at 3.5cm wide so that the screen does not slide out of the slot when pulled out for use, and locks into position at the top of the slot when extended and in use.
The aerial and screen could be spring loaded by design so that it can be either driven by a spring loaded device or an air damping device to enable the screen and aerial to be released together and to work together. The aerial screen remains connected to the slot and locks into position for use when extended.
After use, both eased back into the stored position. The screen eased back down the guide rails into the slot into the stored position and the spring or spring catch locks the screen into the stored position.
For release a control button or pressure is applied to the top of the aerial screen, allowing the spring loaded device or air damping device to be released, and the aerial screen and aerial is released and extended for use.
The aerial screen positioned to work in and out of the slot in front of the aerial but also connected to the metal casing.
The aerial must be positioned at the back of the screen. Thereby the aerial screen offers maximum protection to the head and brain during mobile phone use.
Referring to the aerial and screen in use with a mobile phone.
In figure I and figure 2, the aerial screen is positioned in a slot added to the mobile phone during manufacture of the new design. This screen is also connected to the metal casing by a flexible static earthing connection or flexible electrical connection internally.
The screen and metal casing is totally isolated from the internal electronics of the mobile phone.
No I is the slot added to the phone design. No 2 is the aerial screen added to the mobile phone. This screen is positioned in front of the mobile phone aerial No 3 during manufacture and design in order to protect the mobile phone user's head and brain during phone use.
This screen No 2 will comprise of an electronically conductive material, for example anodised aluminium. or an alloy with a thin coating of lead during manufacture to blend in with the mobile phone and design as in figure 3, 4, 5 and 7.
In figure I and figure 2, the aerial screen is not in use and eased into the slot for storage and locked into stored position.
In order to use the aerial screen as in figure 3, figure 4, figure 5 No 2, the aerial screen would be pulled out when the mobile phone is in use by sliding the aerial screen upwards, along the internal guide rails, up the slot until fully extended above the mobile phone aerial, and the base of the aerial screen locks into position for use at the top of the slot. After use the aerial screen is eased down the slot through the internal guide rails into stored position as in figure 1, 2, 6. The internal guide rails for ease of screen movement can be optional during manufacture.
The aerial screen extension could be spring loaded by design so that it can be either drive by a spring loaded device or an air damping device to enable the aerial and screen to be released together and to work together as shown in figure 3, 4, 5, No 2 and 3.
The aerial screen will slide up the guide rails and extend out of the slot above the mobile phone aerial for use. The aerial screen remains connected to the slot and guide rail and does not slide out of the slot completely due to the final lock position, and by design of the base of the screen which is wider at the base and screen is unable to slide out completely.
After use the screen is eased back down the guide rails into the slot into stored position, and the spring or spring catch locks into the stored position as in figure 1, 2, 6, with the aerial screen positioned into the slot and design of the mobile phone.
A control switch or pressure applied to the top of the aerial screen is used to allow the spring loaded device on an air damping device to be released and the aerial screen and aerial is released and extended for use. Alternatively, the above procedure can be replaced by motorisation.
In Figure 7, shows an example of the aerial screen as described in figure 3, 4, 5. The base of the screen is designed wider so that the screen does not slide out of the slot and locks into position when in use.
A specific embodiment of the invention is described by way of example with reference to the accompanying drawings in which:
Figure I shows a front view of the rounded aerial screen on the mobile phone, resting in the slot in stored position and not in use.
Figure 2 shows a front view of the aerial screen as a square screen on the mobile phone, resting in the slot and in stored position and not in use.
Figure 3 shows the front view of the mobile phone with the square aerial screen extended and in use.
Figure 4 shows the front view of the mobile phone with the rounded aerial screen extended and in use.
Figure 5 shows a side view of the mobile phone with the aerial screen extended and in use.
Figure 6 shows a side view of the mobile phone with the aerial screen eased back into the slot for storage and not in use.
Figure 7 shows the front view of the aerial screen as in figure 3 and in figure 4 on display.
Figure 8 shows the back view of the mobile phone with the aerial screen not in use.
