T here are few pieces of equipment that are common to virtually all healthcare facilities, but portable power devices or power strips (sometimes called portable power taps) are one of them. Whether it is in a hospital, surgery center, doctor's offi ce, or veterinarian's offi ce, power strips are pervasive as the expansion of electrical equipment continues. The eternal problem appears to be eith...

Classification, essential properties, important applications and developement of power semiconductor devices will be explained. Some common power semiconductor devices, power metal oxide semiconductor field-effect transistor (MOSFET), thyristor and some new power devices will be described and discussed.

Field Programmable Gate Arrays (FPGAs) are widely used for implementation of dig ital system design due to their flexibility, low time-to-market, growing density and speed. But the Power consumption, especially leakage and dynamic power has become a major concern for semiconductor industries. FPGAs are less power-efficient than custom ASICs, due to the overhead required to provide programmabili...

This paper mainly deals with the regulation of voltage at wind farm (WF) terminals and the improvement of power quality and WF stability in a WF to Weak-Grid connection. In facilities with moderated power generation, the WF are connected through medium voltage (MV) distribution headlines. A situation commonly found in such scheme is that the power generated is comparable to the transport capaci...

The renewable energy resources rule the world of power generation. Now-a-days wind farms are encouraged for up gradation of energy production, as the wind power is dirt free, readily available renewable alternative. The integration of wind farms with power grid leads to Power Quality (PQ) issues such as voltage sag, swell, flicker, harmonics etc. Most of the industrial and commercial loads are ...

In any digital circuit surface area and power both are very important parameters. In this paper 4bit full adder using transmission gate is designed. To design 4bit full adder two methods are used. First is semi custom design method and second is full custom design method. In first semi custom design method a layout of 4-bit full adder is designed with available width and length of the transisto...

As increasing the clock frequency leads to unmanageable heat and power dissipation the search is on for another way to get more power efficient and faster embedded systems. Given that chip area is also a constraint, we investigate the addition of a custom instruction to the processor instruction set which enables the execution of an efficient complex division. We have implemented software for c...

Smartphones and tablet devices have been rapidly proliferating, and multi-touch interaction, powerful processors and rich array of sensors make these devices an attractive service platform for older users. While there is an increasing number of work investigating the issues that elderly users experience through their interaction with mobile devices, most have focused either on evaluation of low...
