put on a pair of airline-supplied headphones, only to find that the roar of the jet engines prevented him from enjoying the audio.He started making calculations right there on the plane to see if it was possible to use the headphones themselves as a noise-reducing agent.Boseintroduced the f...

NEXRAD relies on the Doppler effect to calculate the position and speed of rain, snow and weather fronts. First, a radar unit emits a pulse of energy, which travels through the air until it encounters an object, such as a raindrop. Then the unit listens for an echo -- energy reflected...
Police use dopler radars that only look for Doppler-shifted signals, and because the radar beam is a narrow beam, the radar detection only hits one car. Some police are now using a laser technique to measure the speed of cars. This technique is called lidar, and it uses short pulses of...
First, it is supposed to give an accurate representation of the internal organs of a human body, and second, through Doppler signal processing, it is to determine movement within the body (for example, blood flow). From this information a doctor can then make conclusions about the correct ...
The use of seatbelt elements to represent tendons and different combinations of sliprings allows the definition of complex paths, where each muscle is adjustable separately by individual activation curves [3]. This mechanism was implemented in the latest Total HUman Model for Safety (THUMS™) ...
Old-school X-ray machines use X-ray tubes to bombard your body with high-energy X-rays, which are a type of electromagnetic radiation. Like visible light, X-rays are made of photons, which are elementary particles that make up all electromagnetic radiation. For more detailed information on ...
After a mean round trip time \(\,\bar{T}\approx 300\,\mu s\), an ordered sequence of pulses returns to the first coupler and starts its journey again (see Fig. 1c). For any m round trips, the pulses arrive in the photodetectors at different arrival times as $${T}_{{\rm{...
This was not a new technique; astronomers have been measuring the Doppler shift of stars for almost two hundred years. But in 1995 Mayor and Queloz took it one step further, upping the precision of their instrument to new levels, staying on the lookout for even the most minute changes. ...
