Compact Vision for Development and Control of Unmanned Underwater Vehicles

The Mobile & Marine Robotics Research Centre (MMRRC) at the University of Limerick in Ireland created a generic solution for underwater development. During research cruises in February and June of 2005 with the RV Celtic Explorer, MMRRC researchers identified weak points of the overall system integration to address with a virtual underwater lab (VUL). The VUL is a mixed hardware/software tool designed to overcome identified problems; make overall system integration easier; and provide a framework for researchers to develop, implement, and test advanced control algorithms in a combined real-world/simulated environment.

Open Innovation Model Helps P&G “Connect and Develop”

By Ed Getty Research Fellow Procter & Gamble Cincinnati, OH For almost 165 of Procter & Gamble’s 170-year history, nearly all growth came from innovating within the walls of our own R&D organization. In 2000, our newly appointed CEO, A.G. Lafley, realized that P&G’s “invent it ourselves” model was not capable of sustaining high levels of top-line growth. The picture was becoming clear:

2007: The Year in Technology

In 2007, we focused on the global climate, and as gas prices soared, more novel technologies emerged in the development of alternative fuel and power sources. Once again, electronics and computers became smaller, faster, and cheaper, thanks to advances in nano-engineering and alternative battery technologies. Homeland security continued to be a focus of research and development in new ways to protect ourselves and our soldiers. And a number of breakthroughs in the medical field brought the promise of revolutionary new diagnostic and treatment options.

Ultra-Wideband Recording Stretches to Keep Up With Digitizers

Systems designers are always pressing for faster and faster real-time performance, and data acquisition technology continues to evolve to meet that need. Currently available high-performance digitizers perform in the range of 2 to 5 GS/sec, and some new instruments are featuring 7 GS/sec digitizers for transient capture.

Understanding the Unique Requirements of Portable Data Acquisition Systems

Portable data acquisition applications have to meet a number of stringent requirements not present in traditional laboratory systems. Environmental conditions such as extremes in temperature, humidity, shock and vibration, are all factors that must be considered when selecting portable data acquisition equipment. Other concerns include whether the data acquisition equipment is capable of supporting the mix of particular sensors that will be used, as well as if there is adequate memory/storage to support the test.

Virtual Memory

A Very Real Advantage For Embedded Systems Software developers face constant challenges. Not only must their code be functionally correct, it must also be reliable. In addition, competition among software vendors has taken software quality to significantly higher levels. Producing high-quality code has become one of the core requirements in the software industry today as it differentiates leading software vendors from the rest of the field.

Image Sensors Decades Old But Not Yet Mature

There’s no rule that says when a technology becomes mature, but one might think that image sensors would be by now, 40 years after their conception. Nothing could be further from the truth. After decades of use in fax machines, scanners, and camcorders, image sensors are now in the largest growth period in their history, and much of the innovation is still happening.
