Wind Turbine Research and Nanosychronization

New forms of instrumentation can have a significant impact on reliability engineering of wind turbines.  By using techniques for synchronized measurements on wind turbines, their subsystems, as well as on the wind field in front of turbines, makes it possible … Continue reading

Sherlock Holmes in the Cloud

The launch of Apple’s iCloud gives an opportunity to stop up and reflect on cloud computing, and its relationship to nanosynchronization. At one level, the Cloud is just a return to centralized computing (mainframes) from the 1970’s, where airline reservations systems were, … Continue reading

No time lost…portable precision time in your pocket.

Nanosynchronization of multiple transducers requires a common clock source, such as the time signal from GPS.  But when no GPS signal is available, synchronization is still possible, assuming you have a very stable clock, where an atomic clock is as … Continue reading

Up, Up and Away: nanosync takes off

  The maiden flight of the nano-synchronized Aerial Sensor   Can flying transducers be used to map the turbulence field behind wind tubines? This feasibility study shows the instrumentation pod attached to the tethered balloon.  And what does it measure? 3D Windspeed, … Continue reading

The impossible dream made possible

The above photograph shows the turbulence field behind the Horns Rev 1 offshore wind turbines.  Unique meteorological conditions on 12 February 2008 at 1300 hours resulted in the wind turbines creating condensation (i.e. clouds) of the very humid air, thus … Continue reading

Earthquakes and precision timing

The tragic March 11, 2011 earthquake in Japan gives an opportunity to explain how timing technologies play an important role in earthquake detection, monitoring and prediction. News reports tell us about the physical location of the earthquake, including its depth … Continue reading

Bootleg video of the DELTA Aerial Sensor

In Denmark we have a tradition of making movies with crummy, shaking handheld cameras, called the “Dogme” rules. Our paparazzi photographer caught this footage of the product using an iPhone 4  . . . but got thrown out before he had … Continue reading

The world on time, the same time

A key technology necessary to permit globally synchronized sensors is a well-defined global clock.  There are multiple ways to synchronize clocks (see Time Transfer entry in Wikipedia) where the best uses GPS technology. While GPS is widely recognized as giving position … Continue reading
