An investigation was made of 8-hour EEG tracings of sleeping humans exposed to the electromagnetic field of a GSM-standard mobile phone. To analyze the EEG-patterns, manual scoring, nonlinear dynamics, and spectral analysis were employed. It was found that, when human beings were exposed to the electromagnetic field of a cellular phone, their cerebral cortex biopotentials revealed an increase i...

New multimedia smart phones for wireless voice and data communications are now available. In this paper, a new user interface for a Personal Communications Services (PCS) smart phone is described. The user interface is designed around the unique characteristics of mobile wireless applications. Both the physical characteristics of the phone and the way users interact with applications are unique...

The wide and growing use of cellular phones has raised questions about the possible health risks associated with radio frequency (RF) electromagnetic fields. It would be helpful for epidemiologists as well as cellular phone users to obtain the relative exposure levels, because the RF exposure level is very difficult to accurately measure and quantify for all individuals. In this study, a neural...

As the usage of cell phones is markedly increasing worldwide, accidental injuries and even lethal damages caused by cellular phone explosions have been reported lately. Although, cell phone charger explosion related scalding and tissue loss is extremely rare, they generally cause severe damage to tissues and cause severe complications, ending up in hospitalization. We are presenting a case of 9...

Employing electromagnetic waves in mobile communication networks has increased the level of human exposure to fields that may result concerns about health hazards associated involves soaking up cellular phone energy. The body is penetrated by emit from a cell phone. specific absorption rate (SAR) generated head and layers usually expresses thermal effect on tissue. main objective this paper inv...

Background Using cellular phone among adults, teenagers and children has rapidly increased all over the world. Also, the concern on the possible health hazards of Electromagnetic Fields (EMF) induced from cell phones on reproduction has been growing in many countries. The aim was to assess the morphological parameters, survival rate and development of mouse in-vitro embryos obtained by natural ...

The purpose of this paper is to clarify the mechanism of how 3D Information Technologies (3D-ITs) are effective on the improvement of quality, cost and delivery (QCD) in the development process of cellular phones. Investigating some real cases of the integral processes among the mechanical design, the electric design and the artistic design in detail, the results of this paper indicated that th...

Health hazards are of great concern to cellular phone users. One important measure of the effect of electromagnetic radiation into human body is the specific absorption rate (SAR). If the human body is exposed to electromagnetic radiation, the amount of power absorbed by its tissues per mass volume should be limited and not to exceed a maximum SAR value. The cellular phone radiated through its ...

Generally speaking, we could conveniently and directly operate ordinary user interface by hand controller. But along with the progressing techniques and increasing functions of communication equipment for family use, the operation and interaction styles between people and device have become more and more abundant. Most of the multimedia contents can be run and displayed on different kinds of pl...
