kinemometer

plural kinemometers

1. medicineAn electromagnetic device, similar to the velocity ballistocardiograph, for measuring contraction and relaxation in a tendon reflex.

   Measurement of the ankle reflex time by means of a kinemometer has been shown to be a useful aid in the clinical diagnosis of hypothyroidism.

   He suggested that the Lawson kinemometer, a quantitative device for testing the Achilles' tendon jerks, might be a useful method for surveying families for hypothyroidism.

   Typical reflexes of hypothyroid and hyperthyroid children are described; the kinemometer proved useful in diagnosis and treatment of thyroid disorders.

   The development and a practical application of an electromagnetic device (kinemometer) for measuring the reflex speed of the Achilles' reflex also has merit in diagnosing thyroid dysfunction (24) .

2. A highly sensitive type of tachometer.

   M. Jacquemier, inventor of the kinemometer, dynamometer, and other useful appliances, gained the Plumey Prize; and M. Marcel Deprez the Fourneyron, for his ingenious electric experiments on the Chemin-de-fer du Nord.

   The bureau's researches in the war involving electrical principles covered many subjects—the location of enemy batteries by means of sound-recording mechanisms, the electrical control of airplane guns to fire between the propeller blades, time studies of gunfiring, variation of gun pressures, ejection-velocity studies by recoil meters, the development of kinemometers to measure the jumps and whip of a gun on firing, the measurement of projectile velocities inside the gun, and scientific studies of the gun blast.

   The data collection subsystem is a part of the pollution control facilities, and includes the pollutant exhaust supervising instruments installed at the scene of the pollution source (online monitoring and analysis instruments for COD, TOC, pH, water pollution, sulfur dioxide, smoke, dust, and air pollutants), flowmeters and kinemometers, running recording instruments at pollution control facilities (black box), and instruments for data collection and delivery (used for data saving, encrypting, displacement, and receiving, and for sounding alarms).

   Over a 5 days period beginning on November 21, 2011 and ending on November 26, 2011 we deployed an array of hydrodynamic and sediment dynamic sensors on a tripod frame, including two turbidity sensors, two pore water pressure sensors, one sea gauge wave tide recorder, one kinemometer, and one acoustic erosion measuring instrument (Fig. 21.2).
