ac·cel·er·om·e·ter

(ak-sel-er-om'ĕ-ter),
An instrument for measuring the rate of change of velocity per unit of time.

accelerometer

Any instrument used to measure acceleration.

Typically, accelerometers contain a small mass, connected to a stiff spring, with some electrical means of measuring the spring deflection when the mass is accelerated; the type of accelerometer used in gait analysis is usually very small and measures acceleration in one direction, but can be clustered for two- and three-dimensional measurements.

accelerometer

(ak″sel-ĕ-rom′ĕ-tĕr) [ acceler(ation) + -meter]
An instrument that detects a change in the velocity of the object to which it is attached. The device may be designed to record the changes and indicate the direction(s) of the acceleration.

The future for such small accelerometers is promising, says Fan, who compares advances in nanotechnology to the evolution of smaller and smaller computers.
In contrast to a global navigation satellite system (GNSS) such as GPS, which receives signals from satellites orbiting the Earth, the quantum accelerometer is a self-contained system that does not rely on any external signals.
These two models join Model 357A63 to complete an accelerometer family with three models in similarly sized housings that withstand very high temperatures, each with a different mounting option: 357A63, up to 900[degrees]F (482[degrees]C) with stud mount; 357 A64, up to 1,200[degrees]F (649[degrees]C) with screw-tab mount; and 357-M168, up to 1,200[degrees]F (649[degrees]C) with weld-tab mount.
[7] have developed a fall detection system based on a barometric pressure sensor and a triaxial accelerometer located on the waist.
To our knowledge, six studies have validated methods for using two accelerometers in hospitalized patients for specifically measuring posture [12-14,18-20], including four in an acute ward setting [13,14,18,20].
Two types of the vibration sensors that employ the triple axis accelerometer sensor are MMA7361 and ADXL335, however only MMA7361 is applied to detect the leakage along the pipeline.
In these cases, it's very important to be able to measure the input forces from the stinger as well as the response at other places in the structure where the accelerometers are placed.
* The SCA10H-D01 solution, which is a solderable PCB module housing both the accelerometer and microcontroller with embedded algorithms
As far as specific applications of tilt measurement are concerned, accelerometers are embedded in such equipment as various portable digital devices (e.g., cellular phones, photo cameras, computer projectors, GPS receivers, and game consoles).
Theoretical Development of the Method for Multiple Accelerometers Case
These parameters are expected to be useful for interpreting the results of multiple-laboratory comparisons of three-axis-accelerometer calibration capability and are complementary to the cross-sensitivity matrix method widely used in applications of three-axis accelerometers. Understanding the relation of our work to the work cited in the references presupposes knowledge of our results, so it is postponed to the discussion at the end of the main text.
