Last week I posted an article on a simple C++ template class, XYDataArray, I used in my system development tool. The main purpose of this template class is to store and sort general data types. I needed to implement the same thing in Java, since the tool I developed has a compatible Java version. I checked the Java SDK documentation before writing my own code, and found that almost everything I needed is already there, like the C++ case.

Some time ago, I stated in another article that I d take the idea of location broadcasting and develop a mobile solution as a follow-up. The problem back then was I had no means to get location data off of a cell phone, or a way to make it useful. My, how times have changed since then! In this article, I ll demonstrate how to get your phone s GPS coordinates…

Over the past ten years there has been a revolution in the devel- opment and acceptance of mobile products. In that period, cel- lular telephony and consumer electronics have moved from the realm of science fiction to everyday reality. Much of that revolu- tion is unremarkable – we use wireless, in its broadest sense, for TV remote controls, car keyfobs, travel tickets and credit card transactions every day. At the same time, we have increased the number of mobile devices that we carry around with us. However, in many cases the design and function of these and other static products are still constrained by the wired connections that they use to transfer and share data.

Without doubt, the age of information communications is upon 11s. The rapid pace of technological advancement in digital data communications can be wit- nessed in a multitude of applications in our day-to-day existence. In recent years, the widespread proliferation of wireless digital cornmunications hass been readily accepted by the general population worldwide; this is nearly unpa~rallcled in few other human scientific achievements in terms of scope and speed of devel- opment.

The outcome of the 3GPP SAE (system architecture evolution) technical study and specification work is a set of standards that specifies the evolution of the packet core network for GSM/GPRS and WCDMA/HSPA to an all-IP architec- ture and enables a feature-rich ‘common packet core’ for radio accesses devel- oped within 3GPP and also by other standardization fora.

This paper presents a new type of electromagnetic damper with rotating inertial mass that has been devel oped to control the vibrations of structures subjected to earthquakes. The electromagnetic inertial mass damper (EIMD) consists of a ball screw that converts axial oscillation of the rod end into rotational motion of the internal flflywheel and an electric generator that is turned by the rotation of the inner rod. The EIMD is able to generate a large inertial force created by the rotating flflywheel and a variable damping force devel oped by the electric generator. Device performance tests of reduced-scale and full-scale EIMDs were under taken to verify the basic characteristics of the damper and the validity of the derived theoretical formulae. Shaking table tests of a three-story structure with EIMDs and earthquake response analyses of a building with EIMDs were conducted to demonstrate the seismic response control performance of the EIMD. The EIMD is able to reduce story drifts as well as accelerations and surpasses conventional types of dampers in reducing acceleration responses.
