One of the mysteries of the English language finally explained.
An instrument for measuring acceleration, typically that of an automobile, ship, aircraft, or spacecraft, or that involved in the vibration of a machine, building, or other structure.
- ‘The physical activity tests were validated using electronic accelerometers to measure levels of activity minute by minute.’
- ‘An accelerometer was placed on one arm to measure gross body movements.’
- ‘For example, sensors called accelerometers - which are used to cue airbags to deploy - can detect changes in speed and direction.’
- ‘The accelerometer is used to measure shocks and vibration caused by road roughness while the GPS unit records the truck position.’
- ‘More recently, physical activity has been objectively measured through the deployment of accelerometers that are calibrated to monitor activity levels by the minute.’
- ‘One unit malfunctioned due to failure of one of the three internal accelerometers during a measurement period at home, and the subject was retested with another device.’
- ‘The researchers then attached motion recorders - small accelerometers measuring how often and vigorously a limb moves - to the dominant leg and arm of each child.’
- ‘A small sensor, the accelerometer, placed nearby then detects the sound waves and analyses their acoustic signature.’
- ‘Other devices include oxygen sensors to check exhaust gases, accelerometers to detect any sudden sharp braking, and a range of pressure and temperature monitors.’
- ‘In addition, NASA's second redesigned tank has been outfitted with temperature sensors and accelerometers, used to measure vibration.’
- ‘For more rigorous demonstration of the forces involved, Dial also used two accelerometers to measure the acceleration in the forward and vertical directions.’
- ‘Additional accelerometers can measure the vehicle's linear accelerations and angular acceleration about the spin axis.’
- ‘In a passenger car, a linear accelerometer located near the front axle measures higher lateral acceleration than in the center or rear side.’
- ‘The IMU consists of two main sensor types: gyroscopes or ‘gyros’ to measure angular rates and accelerometers to measure velocity rates.’
- ‘They were instructed to wear the accelerometer during all waking hours, to carry out their usual activities, and not to remove the device except for bathing and sleep.’
- ‘After vibration data is measured using the accelerometer and converted into digital format, they are then stored in a computer.’
- ‘The speed and force pattern of the club head was measured by a miniature accelerometer attached to the club head.’
- ‘A monitoring system, including tension sensors, accelerometers, and deformation gauges, will be put in place for purposes of bridge maintenance.’
- ‘Accelerations were measured using accelerometers mounted rigidly to the vehicle and connected to a data logger.’
- ‘To detect hard braking or cornering, the system uses an accelerometer that detects high g-forces on the vehicle.’
