Blood Velocity Meter. A continuous ultrasonic wave in the megahertz region is scattered as it passes through blood. The back-scattered part of the signal can be collected by a receiving transducer next to the transducer emitting the continuous waves, and the returning signal will be shifted in frequency in proportion to the velocity of the blood in the vessel. This Doppler frequency shift can be detected and applied to a frequency meter(e. g. zero crossing detector) or frequency analyzer to produce a signal proportional to blood velocity.  2, record 7, English, - blood%20velocity%20meter

With the difference frequency between oscillators adjusted to zero with pure carrier gas flowing through the detector, the presence of a foreign vapor in the cell will produce a different frequency which is linearly related to the amount of material introduced through an injection port in the carrier gas stream and inversely proportional to the absolute temperature for a given component at a constant density or concentration in the cell and for a particular operating frequency.  2, record 8, English, - Clapp%20oscillator

(...), the MTD [Moving Target Detection] principle involves dividing up the entire radar coverage area into small range-azimuth cells-(...) called ’coherent processing intervals’(CPI). Eight pulses generated at a constant repetition frequency are assigned to each cell, and each return is subjected to Doppler filtering over a range of velocity values. The particular feature of MTD is its ability to measure the density of clutter and to detect the sudden presence of an additional element-such as an aircraft moving into a particular cell-even though it may have zero relative velocity on account of its tangential track.  1, record 20, English, - coherent%20processing%20interval

Le principe du MTD [Moving Target Detection] est de diviser la zone couverte par le radar en secteurs définis en distance et en azimut (...) et appelés «intervalles de traitement cohérent» (ITC). A chaque secteur sont affectées huit impulsions émises selon une fréquence de répétition constante et chaque écho est soumis à un filtrage Doppler couvrant toute une gamme de vitesses. La caractéristique essentielle du MTD est son aptitude à mesurer la densité des échos parasites et à y détecter la présence soudaine de tout élément nouveau - tel qu'un aéronef entrant dans un secteur donné - même si sa vitesse relative est nulle du fait que sa trajectoire est tangentielle.  1, record 20, French, - intervalle%20de%20traitement%20coh%C3%A9rent
