Problems solved by technology

This priming technique worked well for older phones, but has proven unreliable for newer phones, which have false triggers that demand power from the battery (thereby causing current to flow) and cause noise and possibly Applications with unacceptable reduction in battery life, such as games and other entertainment applications

Embodiment Construction

[0029] All electromagnetic radiation consists of oscillating electric and magnetic fields, and the frequency (the number of times the wave oscillates per second) determines the nature of the oscillating electric and magnetic fields and the applications that can be made of them. Frequency is measured in Hertz or Hz, 1Hz is one oscillation per second, 1kHz is one thousand oscillations per second, 1MHz is one million oscillations per second, and GHz is one billion oscillations per second. Frequencies from 30KHz to 300GHz are widely used in telecommunications (including radio broadcasting and television broadcasting) and include radio frequency bands.

[0030] Cellular mobile services operate on government-approved frequencies, generally within the frequency ranges 872-960MHz, 1710-1875MHz and 1920-2170MHz. These frequencies are in the microwave frequency band encompassing the range 300MHz-300GHz. Other applications in this range include radar, telecommunication links, satellite ...

Abstract

A device adapted to fit within, or to be positioned adjacent to, a cellular handset or other personal communication device, for remedying the potentially harmful effect on humans or animal life of RF transmissions, and including an antenna responsive to the presence of RF radiation generated by the handset, signal analysis means for identifying the type of RF transmissions detected which is coupled to activate remedial signal generation means, which is arranged to provide a noise signal to a coil for providing an electromagnetic field in the vicinity of the handset, to disrupt the potentially harmful effects of the RF transmissions.

Description

technical field [0001] The present invention relates to methods and devices for protecting living systems from the potentially adverse effects of electric, magnetic and electromagnetic fields on them. Background technique [0002] There are many conflicting views on the effects of electric, magnetic and electromagnetic fields on living systems. However, the evidence that certain fields can be harmful to living systems, including humans, is considerable. It is also possible that the adverse effects are long-term and their full impact has not yet been recognized. [0003] The use of electric equipment has increased significantly globally. All electrically powered devices have associated with them electromagnetic field emissions that, to varying degrees, have the potential to affect human health. Of particular concern are devices that emit radio frequency (RF) signals and are used in close proximity to the human body, such as cellular telephones and other personal communicat...
