Free Seminar: Nanosynchronization and IoT (Internet of Things)


IoT is booming as the next hot thing, and “nanosynchronization” will set off an avalanche of new, mind-blowing applications.

Join us on 26 May, 2016 from 10.00 to 14.30 for a look deep into the crystal ball of the Internet of Things (IoT), and how it is impacted by nanosynchronization. Come and hear about the vision of the future, along with real, down-to-earth discussions and technology demonstrations.

Using GPS time, it is possible to synchronize sensors and actuators anywhere on earth with 50 to 100 ns precision.

This has amazing potential applications:

  • Where? Source determination
    • Synthetic directional arrays to determine location of
      • noise sources
      • explosions/gun shots
      • Lightning strikes
      • Electromagnetic pulses
      • Ground tremors caused by avalanches, volcanic activity, mud slides, earthquakes
  • When and Why? Causality
    • Measuring the precise sequence of events makes it possible to determine what came first and which events followed.
      • Sequence of events in accident determination
      • “Who shot first” in crime investigation
      • What triggered a building collapse?
      • How does a lightning strike propagate through the grid and causes damage
      • Physiological and neurological responses in humans and animals.
  • How: Advanced scientific experiments
    • Building and bridge stability
    • Earthquake and geophysical event monitoring
    • Wind Turbine system analysis: From wind in to power out.
    • Smart grid characterization
    • Modal analysis of aircraft, ships, structures
  • Control: Synchronously Controlling the world
    • Precision Controlled demolition
    • Synchronized traffic flow: cars, planes, trains.
    • Synchronized dynamic feedback to reduce vibration of large structures.

Fact: Light travels 30 cm in one nanosecond.  This means that you can differentiate between events in the time it takes light to travel 15 meters in 50 nanoseconds.

Fact: Sound travels about 300 nm in one nanosecond. So you can determine different acoustic events in the time it takes sound to travel 15 µm (=0.015 mm) in 50 nanoseconds.  For example this means you can acoustically measure the motion of an object that only moves 15 µm!

This seminar marks the conclusion of our 3,5 year EUDP sponsored demonstration project investigating the potential of energy efficiencies made possible by nano synchronization.

Not only will you hear about the project’s history and demonstrated applications, but also enjoy a “ride” into the not too far future, where exciting, but perhaps also “scary” scenarios will show you a world of global, real time synchronized internet of things sensors.

Successful Wind Turbine Demo

Nordtank 500 (36 of 87)

Thursday, December 17, 2015 saw the successful “flight” of the nanosync board (Developed by DELTA) on a Nordtank 500 Wind Turbine (37 m wingspan)  at the Department of Wind Energy test center at Risø, Denmark. (It has a “hot” winter day in Denmark with temperatures of 10 degrees C).

The board, which is the size of a large smartphone, provides 8 DC channels (sampled at 1 kS/s) and up to 4 microphone/accelerometer channels sampled at 48 kS/s.


The demonstration, which ran without interference from Murphy’s law, demonstrated

  • Successful GPS signal lock despite the rotational speed and unfavorable antenna mounting. (Tip speed about 170 km/h), lower at the mounting position.
  • Proper operation of the circuit board in a high G force environment
  • High quality data acquisition
  • Real time Bluetooth monitoring of GPS status to a smart phone while the wings were rotating

Nordtank 500 (34 of 87)

The Status Value (Ox)04 indicates GPS Acquired.

Data from the on board 3D accelerometer showed values along 3 axes


and the corresponding FFT Spectrum (with 0.04 Hz Resolution) showing a rotational frequency of 0.44 Hz or 2.64 RPM. (the amplitude of the plots is uncalibrated)


Long-term ground based measurements have demonstrated less than 20µs time difference between two boards sampling at 48 kS/s facing different groups of satellites.

The project is funded by the Danish EUDP research fund and the participating partners.

Nanosync Symposium December 4, 2013: It’s about time

ATV, the Danish Academy of Technical Sciences will host a half day symposium  about “Nanosynchronization: Technology and Applications” on Wednesday afternoon, December 4, from 13.00-16.30 at DELTA in Hørsholm, Denmark. The seminar targets technology professionals in a wide range of applications with a broad, inter-disciplinary approach.

You can register here.

Professor Charles Curry, Managing Director of Chronos Technology Ltd. UK, will be the keynote speaker with the presentation:

From Nanoseconds to Light Years – A Review of How “Time” Drives Our World

 “Time” plays a vital part in our World today.  We never have enough of it and yet, without it, nothing would get done. Charles will take the audience on a journey through “Time” where the audience will be encouraged to interact with the speaker. Case studies, photos and video clips will help to illustrate key points.

The journey will begin with a wide ranging review of the components of “Time” and time scales. These include the three essential components: Time of Day, Timing and Phase. Then more aspects of “Time” will be explored including clocks, UTC (Universal Coordinated Time), nanoseconds & light years, the speed of Light, frequency, the electromagnetic spectrum, leap seconds, bending time, relativity, gravity, time transport and more.

The journey will continue by exploring why accurate “Time” is vital in everyday life including a review of industries and applications that just would not work without “Time”. These include Telecoms, Power, Computing, Navigation, Transport, and Broadcasting.

Finally what happens when time goes wrong or gets damaged? Can we interfere with SatNav? What would happen if the Sun got “wind”? Can we make time go backwards? Does time change when we go into space?

Technologies to be discussed in the seminar

The symposium will cover broad spectrum of technologies for timing including

Applications discussed will include

  • Localization
  • Synthetic aperture imaging for acoustics, geophysical exploration, and radar
  • Telecom
  • Synchronized transportation systems
  • Structural analysis and wind turbines.
  • Smart Grid applications
  • Homeland security
  • Test and Measurement and control systems
  • Internet of things, “intelligent dust”

Presentation Schedule

Ample time will also be provided for networking and brainstorming.

You can register here.

Nanosync comes to Wind Turbine noise Measurements

DELTA recently released the “noiseLAB Wind” noise measurement system for wind turbines. One or more microphone nodes communicate via Wi-Fi to a central data collection computer, where data is analyzed using FFT and 1/3 octave analysis.

Precision timing is not critical for the mainstream applications of the system, but for detailed research applications, it is possible to synchronize the various A/D converters in the system using National Instruments PXI-based system fronts-end with GPS synchronization. 

On a parallel track, the nanosync sensor board under development in the EUDP sponsored reseach project is now going into board layout, and we expect prototypes to be available for project partners near the end of 2013. This small battery-power unit will provide multiple input channels for microphones and other analog transducers, and support 24 bit A/D converters that are GPS synchronized. Acquired data will be streamed to the on-board 32 GByte flash memory.

Additional partners may still have the opportunity to join the project.  For more information, contact Carsten Thomsen at

nanosync at the Wind Turbine Research Conference

  • Logo

DELTA will present several papers at the Danish Wind Power Research Conference 2013 on May 27 and May 28, 2013. One of the papers will feature applications of nanosynchronization:

“The Wind Farm as a System”: Total system analysis and modelling using synchronized sensors.

The future perspectives of nanosynchronization for instrumentation of a complete wind farm, including its interfaces to the grid, as well as arbitrary nodes anywhere on the grid will be presented by Carsten Thomsen, Director of Engineering, DELTA May 27 in the afternoon. By using synchronized measurements, cause/effect relationships can be explored between any components in the system.  For example, the effect of a particular wind gust can be related to the wind blade deflection, the associated tower load, the instantaneous impact of the power generation, the effect of shadowing on downwind turbines, and ultimately to potential flicker in the home of Mr. and Mrs. Larsen 15 km away.

Thus when all instrumentation is on a common time base, it also becomes possible to explore interdisciplinary effects, not only from a measurement standpoint, but also from a modeling standpoint using CFD, FEM, and other models.

The link to the conference is here and the link to the program is here.

The official name of the paper is

“The Wind Farm as a System”. Total system analysis and modelling using synchronized sensors. Carsten Thomsen, DELTA.

Additional papers related to wind turbine noise presented by DELTA include:

  • Impact of noise from Wind Turbines, Torben Holm Pedersen, Senior Technology Specialist DELTA. (May 27 morning). This paper will also include an overview of current state of the art in low frequency measurement and annoyance evaluation.
  • Wind Turbine noise at night: Consultant Lars Sommer Søndergaard. DELTA (May 27, late afternoon)
  • Wind Turbine Noise Measurements and prediction: Techniques and challenges, Carsten Thomsen, Director of Engineering, DELTA (May 27, late afternoon)
  • Tonality in Wind Turbine noise, Consultant Lars Sommer Søndergaard, DELTA (May 27, late afternoon)

Demonstration Project Approved

The Danish Energy Agency (energistyrelsen) has approved the funding  (EUDP) of a demonstration project “Improved wind turbine efficiency using synchronized sensors” with the following goals:

To improve the efficiency of wind turbine and wind turbine farms using synchronized sensors on wind turbines, their wings, and in wind fields. The technology is used in development, test, modeling, and active control of both wind turbines and wind turbine farms, thus optimizing their efficiency, life span, durability, and noise emissions while lowering production costs and increasing reliability.

The project includes the development of a nano-synchronized data acquisition front end and an inflow sensor to mount on the leading edge of the turbine blade.

Participants in the project are


DTU Wind Energy (Danish Technical University)

Siemens Windpower A/S



This project is part of the long term goal of miniaturizing the synchronized front end to the size of a golf ball.

What wrong with this picture?


 Picture Courtesy of EAS/Hubble.

What can be wrong with such a beautiful picture take by the Hubble Telescope.  As a picture, nothing, but from an instrumentation standpoint the various objects in the picture do not have a common time base due to the thousands of light years difference in distance between them, thus giving different time time axes for each star/galaxy.

This would correspond to taking a family picture on which Adam and Eve, your great grandfather, and great great great great grandmother showed up on the same picture as you and your children.

Yes, the Hubble camera did indeed  capture the light arriving at its camera at the same time, but each of the light sources are on a different time scale.   Obviously, this is hard to correct 😉 but points out the importance of being aware of potential synchronizations issues between transducers in distributed sensor systems for more down-to-earth applications.

You may also be interested in reading about light in space getting bounced around, in this case with a 170 year old reflection.

How “long” is a nanosecond?

The ruler below from Chronos gives the answer:  about 30 cm, or 12 inches!  What a handy “rule of thumb”;-)

And in case you didn’t notice, the board next to the ruler is the DELTA nanosync Aerial Sensor board, it’s about 1 ns squared.
