Good memory, Rob! Yes, this does work, and in the future this will really give marine biologists a weapon to keep track of a number of sea creatures, sharks, of course, among them. But imagine the possibilities for tracking other types of fish and observing migration paths, depletion of fish in overfished areas and other patterns of behavior. Long-term these types of robots could prove to be valuable ecological and even economical tools. There also could be other applications for a wireless network in the sea.
That is funny, naperlou, but seriously, the implications of turning these tags into a network is a great idea. If the connections between enough sea creatures were initiated, a real-time 3D view of the enviromment and creature interaction could be invaluable for understanding the interrelationships of sea dwelling creatures, and their migration patterns. This could also give early warning to adverse environmental conditions.
Chuck, as you probably remember, Elizabeth did a story about great white tracking in the Pacific off San Francisco. If it works, it could be helpful on the East Coast. That is, if they could tag every great white.
It would be nice if OTIS could track some of the great whites that spotted on the East Coast this past summer. It's certainly better than a guy with binoculars standing in a shark tower.
Ann, if this is like a social network for sharks, the next step is letting them communicate with each other. With all the advances in robotics that should be something that is being researched. Then, Facebook could sell ads to them.
Ann, such real time tracing technologies will help to identify the moving pattern of shark. Moreover I think a small modification in the system may help to extend the study to other underwater specious too. but am not clear how long (range) the signals can be transmitted through under water, which can disintegrate on long distance under the acoustics conditions.
Andrew Morris designed a circuit that could detect a stroke victim's groan and convert the sound into a signal so caregivers would know when help was needed.
New disc magnet motors fit into the design trend of stepping up to closed loop performance while maintaining the cost advantage of stepper motor technology.

For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
