This recording frequency is sufficiently high when using measures of acceleration primarily as a proxy for energy expenditure [17].
Curiosity's rover inertial measurement units (RIMUs), which are typically used to measure acceleration during navigation, were instead used to measure the force of gravity being exerted in a specific location while the rover was in one place.
The six dice devices measured acceleration using an ADXL330 3-axis MEMS accelerometer sampled by a TI MSP430F1611 microcontroller running at 8 MHz and providing 10 kB RAM.
That atom interferometer can be used to measure acceleration or gravity or rotations with very high accuracy -- in fact, in terms of acceleration or gravity, better than any other way of doing it.
Vibratory power can be estimated experimentally by measuring accelerations.
The frequency responses of the acceleration estimated by NP, KF and NPEKF are compared with those of the measured acceleration via linear accelerometer.
Main Outcome Measures: Shocks were examined by using peak acceleration and the frequency at which peak acceleration occurs for the seat and footrest.
It is necessary to measure accelerations by accelerometers or other devices in model tests for the accurate prediction of vertical accelerations in real ships.
Two electrodes are placed above the ulnar nerve and the response to the nerve stimulation is measured by using a small piezoelectrode acceleration transducer distally placed on the volar side of the thumb.
Spectra were collected at 295 K, 77 K and 5 K by using a constant acceleration drive system (WissEL) in transmission mode with a 57Co/Rh source and calibrated against a 7 μm thick α-57Fe foil measured at room temperature.
