Modular, self-reconfigurable robots show the promise of great versatility, robustness and low cost. Polybot is a modular, self-reconfigurable system that is being used to explore the hardware reality of a robot with a large number of interchangeable modules. Three generations of Polybot have been built over the last three years which include ever increasing levels of functionality and integration. Polybot has shown versatility, by demonstrating locomotion over a variety of terrain and manipulating a variety of objects.

A MODULAR FUEL CELL, MODULAR DC–DC CONVERTER CONCEPT FOR HIGH PERFORMANCE AND ENHANCED RELIABILITY
ABSTRACT
Fuel cells are electrochemical devices that process H2 and oxygen to generate electric power, having water vapor as their only by-product. The voltage resulting from the reaction of the fuel and oxygen varies with the load, and ranges from 0.8 V at no-load to about 0.4 V for full-load. Due to their low output voltage, it becomes necessary to stack many cells in series to realize a practical system. The propos ....etc

I T's Challenge

In the past three tears, the world has changed for information technology groups. In the late 1990s, the predominant problem was deploying equipment and software quickly enough to keep up with demand for computing. While the tech sector boomed on Wall Street, money was no object. IT budgets swelled and the numbers of computers in data centers grew exponentially.

Now, in the early 2000s, the picture is very different. IT budgets are flat down, yet business demand for IT services continues to escalate. This co ....etc

Modular Embedded Internet Software Support

The ever increasing penetration of micro processor-based embedded systems in now so many market areas and product types is leading to more and more attractive commercial opportunities. Moreover, the exponential growth of the internet in the last few years, and the consequent slump of the costs of internet services in general, made network connectivity more a must than a desirable feature in many commonly used embedded equipments. Mobile and smart phones, PDA's, Hand-held devices are today definitely ....etc

A modular hydro jetting tool for fracturing well formations the tool has a plurality of jetting modules. Each jetting module has a plurality of jetting nozzles therein. A sleeve disposed in each jetting module except the lowermost module, and each sleeve is moveable from a first position covering the jetting nozzles in the corresponding module to a second position covering the jetting nozzles in an adjacent module. Plugs may be pumped into the tool to move each sleeve sequentially, thereby operating the jetting modules sequentially ....etc

Modular Computing

As Janet Matsuda, SGI's director of Graphics Product Marketing, says: Modularity offers both savings and scalability so that customers don't waste their money on what they don't want and can spend it on what they do want. Debra Goldfarb, group vice president at analyst firm IDC, agrees: Modular computing empowers end users to build the kind of environment that they need not only today but over time.To keep up with computing demand while operating within restricted budgets, IT m ....etc
