The Japanese mobile phone markets proved in the late 1990's by selling a great number of attachable intelligent devices with i-mode phone that mobile devices have a market driven need to serve as a gateway to the Internet for devices that are lacking a radio module such as PDA equipment and lap top computers. They are referred to as terminal equipment and when attached to a mobile phone's servi...

This project deals with the problems of utilization of mobile equipment working in the biomedicine field, particularly telemedicine. This field is relatively new; it focuses on the observation of life functions from a distance. Practically developing system works with an ECG sensor connected to mobile equipment, such as PDA/Embedded device, based on Microsoft Windows CE class operating system. ...

It is a very important and to be worthy of research issue which elucidates that how to provide mobile users for roaming among different access technology networks through seamless handoff mechanism. IPv6 will play an important role in the future wireless access networks, each of equipment has its unique IP address. For mobile equipment, IPv6 have mobility support (Mobile IPv6). Therefore, in or...

In our days, interactive multimedia based client equipment (desktop), a palmtop or an equipment capable of mobile sound transmission (mobile phone, communicator) are all, though in different ways, suitable for interactive (multimedia based) knowledge transfer. The aim of developers is to pass the same knowledge no matter through what kind of medium. The practical realization of such multifuncti...

A major part of the study of coupling paths between mobile communication systems and electronic equipment is the prediction of the level of EMI incident of equipment ports due to external cables. At mobile radio frequencies external cables are generally greater than a wavelength in length and may be the dominant coupling path of EMI into equipment electronics. A two year work package was undert...

Wireless communications have revolutionized the way the world communicates. An important process used to secure that communication is authentication. As flaws in the security of a wireless network are discovered new protocols and algorithms are required to meet those security issues. When creating new algorithms and systems it is possible that the existing equipment may not be able to implement...

Paraformaldehyde powder, depolymerized by heat, produced formaldehyde gas that was effective in sterilizing laboratory rooms, a mobile laboratory trailer, various surfaces, fiberglass filter medium, and specialized laboratory equipment. A sporulating and nonsporulating strain of bacteria, a virus, and a bacterial toxin were used as test agents. The dissemination procedures and equipment, the as...
